This disclosure generally relates to textiles and garments, and methods for manufacturing the same, and more particularly relates to textiles and garments suitable for aquatic activities, and methods for manufacturing the same.
There are various types of garments that are commonly used for aquatic sports (e.g., surfing, sailing, paddling, swimming, diving, scuba diving, etc.) and other aquatic activities (collectively, “aquatic activities”).
It is known in the art to provide a garment having a knitted textile. Such garments can be constructed of a very high stretch knitted textile and configured to be form-fitting, or can be constructed of a less stretchable knitted textile and configured to fit more loosely. Garments with knitted textiles can have good breathability, drape, and stretch characteristics; however, when exposed to water, such garments can become heavy and cold due to the inherently high absorbent construction of knitted textiles. When a knitted textile becomes saturated with water, the thermal conductivity of the garment is significantly increased due to the high thermal conductivity of water and evaporative cooling effects of the wet knitted textile. Further, the stretch recovery of knitted textiles can be reduced when wet, causing the garment to stretch and sag, and thereby reducing wearer comfort.
It is known in the art to provide a garment having a knitted textile with a durable water repellent (DWR) coating or treatment. Although a DWR coating or treatment can provide some resistance to the absorbance of water, water can still be absorbed during the normal life of the garment. In addition, the effectiveness of a DWR coating or treatment reduces during the normal life of the garment due to washing and abrasion, allowing the garment to absorb more water, and stretch and sag during use.
It is also known in the art to provide a garment having a stretch-woven textile. Stretch-woven textiles can also be relatively light and thin, and can provide excellent coverage of the wearer's body. Stretch-woven textiles can be configured to have excellent stretch recovery compared to knitted textiles, due to reduced friction and movement between yarns when in their elongated state. Improved stretch recovery allows garments having stretch-woven textiles to return to their original shape and therefore provide improved fit and comfort to the wearer. This is particularly important when used in wet conditions.
Yarns within known stretch-woven textiles are typically arranged in a very close and tight structure, with very small gaps between adjacent yarns, as compared to the yarns in known knitted textiles. Stretch-woven textiles can be configured to absorb less water content than stretchable knitted textiles, due at least in part to smaller spaces between yarns. In addition, when a stretch-woven textile is comprised of a hydrophobic material, or is provided with a DWR coating or treatment, the stretch-woven textile can exhibit excellent hydrophobicity compared to knitted textiles, due at least in part to smaller spaces between yarns and/or the relatively smooth surface texture of the stretch-woven textile.
It is known in the art to use a stretch-woven textile to produce a loose-fitting water short for use in aquatic activities. For example, U.S. Pat. No. 7,849,518 discloses a loose-fitting water short that includes a stretch-woven textile.
It is known in the art to use a stretch-woven textile to produce a tight-fitting, high-performance swimsuit. Such swimsuits are known to provide improved hydrodynamic performance and reduced drag. For example, International Patent Publication No. 2009/125438 discloses a stretch-woven textile having a polytetraflouroethylene-based (PTFE-based) coating to provide hydrophobic function for use in high-performance swimsuits. Although such textiles can provide good hydrodynamics for high-performance use, the high modulus of elasticity and the touch of the textile has generally been uncomfortable for use in other garments. Also, the construction of the textile provides good hydrophobic performance when the PTFE-based coating is applied, but the durability of the PTFE-based coating is not adequate to provide continuous water repellency to the garments during normal use.
It is known in the art to provide a substantially waterproof garment. Such garments typically include a substantially waterproof composite material, such as a textile laminated with a neoprene foam or another waterproof film or coating. Such garments are commonly configured to be form-fitting, and include a high stretch knitted textile to allow high stretch and freedom of movement to the wearer. For example, U.S. Pat. No. 7,395,553 discloses a wetsuit material having a wool inner layer attached to neoprene foam. U.S. Patent Publication No. 2012/0023631 discloses another substantially waterproof garment. Substantially waterproof garments can provide good thermal insulation to the wearer, but can have poor breathability. Also, substantially waterproof garments are not suitable for high metabolic activity or warm weather conditions.
Several methods for providing hydrophobic functional layers to textiles are known in the art. The most common methods involve the application of fluorocarbon-based chemicals via a bath or dipping process, pad treatment process, and/or spray or other processes. Other methods known in the art include deposition or polymerization of thin organic or inorganic layers via a process of vacuum vapor deposition. For example, International Patent Publication No. 2014/056966 discloses a method of coating a textile via a process of contacting a fabric with a monomer and subjecting it to low power plasma polymerization in a low pressure vacuum. The monomer can be selected to provide hydrophobicity and/or oleophobicity.

These and other aspects of the present invention will become apparent in light of the drawings and detailed description provided below.
Referring now to the drawings, the present disclosure describes a textile 10 (see
The textile 10 includes a plurality of warp yarns 14 and a plurality of weft yarns 16 that are woven together. The warp yarns 14 include one or more elastic warp filaments 18 and one or more non-elastic warp filaments 20 (collectively, the “warp filaments 18, 20”). Similarly, the weft yarns 16 include one or more elastic weft filaments 22 and one or more non-elastic weft filaments 24 (collectively, the “weft filaments 22, 24”). The respective materials of the filaments 18, 20, 22, 24 are selected such that the textile 10 has a high elastic stretchability in one or both of a weft direction and a warp direction. Also, at least one of the elastic warp filaments 18, the non-elastic warp filaments 20, the elastic weft filaments 22, and the non-elastic weft filaments 24 includes (e.g., are formed of, are coated with, are treated with) at least one hydrophobic material. The inclusion of the hydrophobic material increases the hydrophobicity of the textile 10, and thus increases the ability of the textile 10 to repel water during wet conditions.
Referring to
The textile 10 (see
The textile 10 can include a predetermined number of warp yarn 14 threads per inch and/or a predetermined number of weft yarn 16 threads per inch. In some embodiments, for example, the number of warp yarn 14 threads per inch, and/or the number of weft yarns 16 per inch, can be: (i) between 130 and 200 threads per inch; (ii) between 130 and 180 threads per inch; or (iii) between 150 and 250 threads per inch.
The textile 10 defines a surface density (e.g., a mass per square meter) that can vary depending on one or more design considerations. In some embodiments, the surface density of the textile 10 can be between 80 and 250 grams per square meter (gsm).
The warp filaments 18, 20 can be configured relative to one another in several different ways. The weft filaments 22, 24 can be configured in a same or different manner as the warp filaments 18, 20. In some embodiments (see
The warp yarns 14 and the weft yarns 16 can each include a predetermined number of filaments 18, 20, 22, 24. Also, the relative numbers of elastic filaments 18, 22 and non-elastic filaments 20, 24 included in each of the warp yarns 14 and the weft yarns 16 can be predetermined. The respective numbers of warp filaments 18, 20 can be the same as or different than the respective numbers of weft filaments 22, 24. In some embodiments, the warp yarns 14, for example, can each include: (i) between ten percent and forty percent (10-40%) elastic warp filaments 18 and between sixty percent and ninety percent (60-90%) non-elastic warp filaments 20; and/or (ii) between fifteen percent and twenty-five percent (15-25%) elastic warp filaments 18 and between seventy-five percent and eighty-five percent (75-85%) non-elastic warp filaments 20. Further, in some embodiments, the warp yarns 14 can each include: (i) only one elastic warp filament 18; and/or (ii) between five and eighty (5-80) non-elastic warp filaments 20.
The warp yarns 14 and the weft yarns 16 each have a linear mass density that can vary depending, at least in part, on the respective numbers of filaments 18, 20, 22, 24 included therein. The linear mass density of the warp yarns 14 can be the same as or different than the linear mass density of the weft yarns 16. The respective linear mass densities of the warp yarns 14 and/or the weft yarn 16 can be: (i) between 5 and 80 denier; (ii) between 5 and 30 denier; (iii) between 20 and 30 denier; (iv) between 30 and 60 denier; or (v) between 20 and 80 denier.
The warp yarns 14 each define a warp yarn surface area, and the weft yarns 16 each define a weft yarn surface area. The warp filaments 18, 20 can have one or more predetermined cross-sectional shapes that can be selected at least in part to achieve a desired warp yarn surface area, which in turn can aid in preventing the textile 10 from absorbing water during wet conditions. Similarly, the weft filaments 22, 24 can have one or more predetermined cross-sectional shapes that can be selected at least in part to achieve a desired weft yarn surface area, which in turn can aid in achieving a desired water absorbency of the textile 10. In some embodiments, for example, the non-elastic warp filaments 20 and the non-elastic weft filaments 24 each have round cross-sectional shapes that allow for reduced warp yarn surface areas and reduced weft yarn surface areas, respectively, and in turn aid in preventing the textile 10 from absorbing water during wet conditions.
The warp yarns 14 and/or the weft yarns 16 can be texturized using one or more known texturizing techniques (e.g., draw texturizing, air texturizing). Such texturing can be advantageous in that it can provide the textile 10 with a soft hand feel.
The elastic warp filaments 18 and the elastic weft filaments 22 can be made of various different elastic materials. Acceptable materials for the elastic warp filaments 18 and the elastic weft filaments 22 include, but are not limited to, an elastic polyurethane and an elastane.
The non-elastic warp filaments 20 and the non-elastic weft filaments 24 can be made of various different non-elastic materials. In some embodiments, the non-elastic warp filaments 20 and/or the non-elastic weft filaments 24 include at least one filament made of a synthetic material, and/or at least one filament made of a natural material. In other embodiments, the non-elastic warp filaments 20 and/or the non-elastic weft filaments 24 are all made of a synthetic material. Acceptable synthetic materials for the non-elastic warp filaments 20 and the non-elastic weft filaments 24 include, but are not limited to, a polyester, a polyamide (e.g., nylon), and a polypropylene. Acceptable natural materials include, but are not limited to, wool and cotton.
As indicated above, at least one of the elastic warp filaments 18, the non-elastic warp filaments 20, the elastic weft filaments 22, and the non-elastic weft filaments 24 includes at least one hydrophobic material. In some embodiments, at least one of the filaments 18, 20, 22, 24 is formed of the hydrophobic material. In other embodiments, at least one of the filaments 18, 20, 22, 24 is coated with or treated with the hydrophobic material. In such embodiments, the filaments 18, 20, 22, 24 can be coated or treated with the hydrophobic material before and/or after the warp and weft yarns 14, 16 are woven together to form the textile 10, before and/or after any dyeing of the textile 10, and/or before and/or after any finishing of the textile 10. In still other embodiments, a treatment (e.g., a corona treatment) can be performed on at least one of the filaments 18, 20, 22, 24 to render one or more materials of the filaments 18, 20, 22, 24 hydrophobic.
In some embodiments, the hydrophobic material is a DWR material. The DWR material can include various different chemicals or combinations of chemicals, including, for example, fluorinated polymers, polyurethanes, silicones, paraffins, stearic acic-melamine, dendrimers, nano-materials, and/or other chemicals that are suitable to repel water. The DWR material can be coated onto at least one of the filaments 18, 20, 22, 24 using one or more known techniques (e.g., a pad/cure/dry technique, a bath technique, screen printing, ink jet printing, dip coating, spray coating, foam coating, blade coating, exhaustion, chemical vapor deposition, PECVD, etc.).
In some embodiments, the at least one hydrophobic material is an organic material and/or an inorganic material. The organic material and/or the inorganic material can include various different chemicals or combinations of chemicals, as described below. The organic material and/or the inorganic material can be coated onto at least one of the filaments 18, 20, 22, 24 using one or more techniques, as described below.
In some embodiments, the organic material and/or the inorganic material includes an acrylate. Fluorinated acrylates, which exhibit very low intermolecular interactions, can be particularly useful in some embodiments, and can have weight average molecular weights up to approximately 6000. Some acrylates have at least one double bond, and in some instances at least two double bonds within the molecule, to provide high-speed polymerization. Examples of acrylates that can be particularly useful here are described in U.S. Pat. No. 6,083,628 and International Patent Publication No. 1998/18852.
In some embodiments, the inorganic material includes organosilanes and/or metal alkoxides (e.g., titanium, tungsten, and/or zinc). In other embodiments, the organic material and/or the inorganic material includes a methacrylate polymer or oligomer. Vacuum compatible oligomers or low molecular weight polymers include diacrylates, triacrylates, higher molecular weight acrylates functionalized as described below; aliphatic, alicyclic, or aromatic oligomers or polymers; and fluorinated acrylate oligomers or polymers.
In some embodiments, the organic material and/or the inorganic material includes one or more functional materials that provide additional functionality, including, for example: (i) antimicrobial materials formed from monomers and/or sol-gels with antimicrobial functional groups and/or encapsulated antimicrobial agents (including chlorinated aromatic compounds and naturally occurring antimicrobials); (ii) fire retardant materials formed from monomers and/or sol-gels with a brominated functional group; (iii) self-cleaning materials formed from monomers and/or sol gels with photo-catalytically active chemicals present (including zinc oxide, titanium dioxide, tungsten dioxide and other metal oxides); and (iv) ultraviolet (UV) protective materials formed from monomers and/or sol-gels that contain UV absorbing agents (including highly conjugated organic compounds and metal oxide compounds).
The organic material and/or the inorganic material can be coated on at least one of the filaments 18, 20, 22, 24 by a process of chemical vapor deposition, PECVD, plasma polymerization, glow discharge deposition, a sol-gel process, and/or other known techniques. In some embodiments, the filaments 18, 20, 22, 24 to be coated can be pre-treated by a cleaning, etching, and/or activation step (e.g., a corona pre-treatment step) using a plasma. In such embodiments, the pre-treatment can aid in improving adhesion of the hydrophobic material to the respective filaments 18, 20, 22, 24. In some embodiments, the organic material and/or the inorganic material can be coated on at least one of the filaments 18, 20, 22, 24 in two or more steps, in which a coating is first applied on a first surface, and then applied on a second surface. In some embodiments, the organic material and/or the inorganic material can be coated on the filaments 18, 20, 22, 24 that are exposed after the warp and weft yarns 14, 16 have been woven together. In such embodiments, the organic material and/or the inorganic material can be applied in a manner that does not significantly reduce the air permeability of the textile 10 by blocking pores within the textile 10.
In some embodiments, the organic material and/or the inorganic material can be rendered hydrophobic and/or oleophobic by the inclusion of a functional component such as a monomer and/or sol-gel that contains fluorinated functional groups and/or monomers that create a nanostructure on the surface of the textile 10. In such embodiments, the monomer can include the following general formula
CnF2n+1CmX2mCR1Y—OCO—C(R2)═CH2
where n is 2 to 6, m is 0 to 9, X and Y are H, F, Cl, Br or I, Ri is H or alkyl or a substituted alkyl (e.g., an at least partially halo-substituted alkyl), and R2 is H or alkyl or a substituted alkyl (e.g., an at least partially halo-substituted alkyl). In other embodiments, R1 is H, R2 is H, Y is H, and m is 1 to 9. In some embodiments, the monomer include acrylates and methacrylates having perfluorocarbon backbones comprising two to six carbon atoms, such as IH, IH, 2H, 2H-Perfluorooctyl methacrylate or IH, IH, 2H, 2H-Perfluorooctyl acrylate. In some embodiments, the monomer is an organosilane.
In some embodiments in which a PECVD technique is used, the technique can be performed using a roll-to-roll system. In such embodiments, the textile 10 can be guided between first and second rollers and are passed between a plurality of electrode layers used to activate a plasma. The plasma polymerization can be done with relatively low power (e.g., between 5 W to 5000 W) and/or low pressure (e.g., between 10 mTorr and 500 mTorr). The electrode layers can be configured so that both sides of the textile 10 are coated with the organic material and/or the inorganic material. The textile 10 can be degassed by winding the textile 10 from a first roller to a second roller within a vacuum chamber at least one time to remove any moisture content of the textile 10. The degassing process can take place within the same vacuum chamber and roll handling system that is used for plasma polymerization. The degassing process can be done in a separate chamber and then transferred into a polymerization chamber.
In some embodiments in which a PECVD technique is used, the textile 10 can be pre-treated in the form of an activation, cleaning, and/or etching step to improve the adhesion and cross-linking of the coating. The pre-treatment process can be used to remove residues that could reduce the durability of the coating. The pre-treatment can done by passing the textile 10 through a plasma zone. The plasma zone can be formed by introducing an inert gas or a reactive and/or etching gas into the plasma zone, causing a plasma to form in the plasma zone. The out-gassing and pre-treatment steps can be conducted in the same process in the same vacuum chamber.
In some such embodiments, a monomer can be distributed evenly across the chamber and stabilized before the plasma is activated by switching on one or more radiofrequency electrodes. The monomer flow direction can be controlled and switched between different flow directions during a single process. The monomer can be used to strike the plasma to form the deposited polymer coating which thereby substantially obviates the need to use an inert gas, such as helium, nitrogen or argon, as a carrier gas. A carrier gas such as helium or argon can be used to provide stability of the plasma inside the plasma chamber, thereby providing a more uniform thickness of the coating.
As indicated above, in some embodiments, at least one of the filaments 18, 20, 22, 24 can be coated or treated with the hydrophobic material after the warp and weft yarns 14, 16 are woven together to form the textile 10, after any dyeing of the textile 10, and after any finishing of the textile 10. That is, in some embodiments, the finished textile 10 can be coated or treated with the hydrophobic material. Further, the coating or treatment of the hydrophobic material can be applied to the garment 12 or a portion thereof, as described below. In some such embodiments, a PECVD and/or plasma polymerization technique can be used to apply a coating of the hydrophobic material. In other embodiments, one or more of the other techniques described herein can additionally or alternatively be used. In some instances, it can be advantageous to coat or treat the finished textile 10 and/or the garment 12, as opposed to coating or treating the pre-woven filaments 18, 20, 22, 24, because doing so can permit simultaneous application of the coating or treatment to the filaments 18, 20, 22, 24 as well as any seam construction components and/or trim included in the finished textile 10 and/or the garment 12.
The hydrophobicity of the textile 10 can be tested by a spray test according to the AATCC 22 standard of the American Association of Textile Chemists and Colorists (AATCC). In some embodiments, the textile 10 is configured to achieve: (i) a score of at least 80 after 20 sprays; (ii) a score of at least 80 after 30 sprays; and/or (iii) a score of at least 80 after 50 sprays. In some embodiments, the textile 10 has a contact angle for water that is at least 100°, and/or the textile 10 has an oil repellency level of at least 3 according to the ISO 14419 standard of the International Organization for Standardization (ISO).

The padding 50 can be positioned on the garment 12 such that, when the garment 12 is worn, the padding 50 is located proximate an area of the wearer's body where padding is desired or required (e.g., seat, knee, elbow, shin, shoulder, spine, or other area). The padding 50 can be made of various different materials, including, for example, open and/or closed cell foam (e.g., neoprene), EVA, a polyurethane, a polystyrene, and/or another foam. The padding 50 can include a dilatant material to improve impact absorption. The padding 50 can be attached to the inside and/or outside of the garment 12 using one or more known techniques, including, for example, gluing, stitching, welding, and/or ultrasonic welding.
