Polyester hospitality fabrics

Abstract

A fabric is constructed by weaving on a loom, with a loom setting of between about 78%-88% of firm setting in the greige, using false twist textured polyester warp yarn with about 57-75 ends per inch and air textured polyester weft yarn with about 36-54 picks per inch, and finishing the fabric by scouring (on a jet or on a continuous scouring range) and printing or jet dyeing, and then heat setting at temperature of at least about 350° F. The yarns may be fire resistant (FR), or finished with a durable FR finish. The fabric scores between 4.5 and 5.0 on each of random tumble pilling, brush pilling, and Klopman method roughing and pilling, tests. The fabric also has a surface SMD of at least about 4.3, a bending rigidity 2HB of about 0.1 or less, a compressibility EMC % of less than about 28, a shearing stiffness G value of about 2 or less, and an extensibility EMT % of at least about 3.0. The fabric is especially suitable in the hospitality trade, e.g. for curtains and bedspreads.

Description

BACKGROUND AND SUMMARY OF THE INVENTION

[0002] In the hospitality market, it is highly desirable to be able to make curtains and bedspreads which have good aesthetic values, yet has no pilling or snagging, and overall excellent performance characteristics. Cotton and spun polyester fabrics have good hand but during wear produce fuzzing and pilling. One hundred percent false twist filament polyester products do not significantly pill or fuzz, but do cause snagging (picking) in continued usage. The polyester filament products according to the invention, on the other hand, produce a surface effect that combines the best of the above mentioned products, with no pilling or snagging, as well as having pleasing aesthetics and overall excellent performance. Products according to the invention have been tested through 50 commercial launderings without showing any wear or deterioration. The finished fabric according to the present invention when tested on a Kawabata testing system for aesthetic values, compared to 100% spun and 100% filament polyester fabrics, has more suppleness and drape, a higher co-efficient of friction and a much rougher surface (enhancing in bedspreads reduction in slippage when on a bed, and improving seam slippage in fabricating either bedspreads or curtains), a vast increase in pliability, resulting in better draping of curtains and forming of bedspreads, and excellent bending characteristics, emphasizing softness of hand and pliability.

DETAILED DESCRIPTION OF THE DRAWINGS

[0023] An exemplary method for providing a useful fabric according to the present invention is schematically illustrated in FIG. 1. The fabric is preferably made from false twist textured warp yarn and air textured filling (weft) yarn. The warp yarn is about 140-160 denier, preferably about 150 denier yarn with about 55-65 filaments in either single or 2-ply form. The warp yarn is about 140-160 denier, preferably about 150 denier yarn with about 90-110 filaments, preferably about 100 filaments, in either 2-ply or 3-ply form. Both the warp and weft are preferably 100% polyester yarns, and preferably commercially available Trevira FR (fire resistant) yarns (available from Trevira of Shelby, N.C.), which are known to produce fabrics that have desired properties when they are constructed according to the invention.

[0024] Several specific examples of warp or weft yarns that may be utilized according to the invention are set forth below. While all the yarns are indicated as FR, it is understood that only one of the warp and weft may be FR, or both may be non-FR and the fabric may be FR finished.

[0025] Style A

[0026] Warp ends per inch 65-69

[0027] Filling picks per inch 50-53

[0028] Warp-1/150/60 S.D. FR Polyester—False twist textured

[0029] Filling-2/150/100 S.D. FR Polyester—Air textured

[0030] In most cases a finished ends per inch count of 63-71 and a finished picks per inch count of 49-54 is acceptable.

[0031] Style B

[0032] Warp ends per inch 59-63

[0033] Filling picks per inch 48-50

[0034] Warp-2/150/60 S.D. FR Polyester—False twist textured

[0035] Filling-2/150/100 S.D. FR Polyester—Air Textured

[0036] In most cases a finished ends per inch count of 57-65 and a finished picks per inch count of 47-51 is acceptable.

[0037] Style C

[0038] Warp ends per inch 69-73

[0039] Filling picks per inch 37-40

[0040] Warp-2/150/60 S.D. FR Polyester—False twist textured

[0041] Filling-3/150/100 S.D. FR Polyester—Air Textured

[0042] In most cases a finished ends per inch count of 67-75 and a finished picks per inch count of 36-41 is acceptable.

[0043] The first step in the practice of the method according to the present invention is to weave the fabric on a loom as indicated schematically at 10 in FIG. 1. The fabric is constructed with a minimum loom setting of about 78% of firm setting in the greige based on the Ashenhurst Rule, and a maximum of about 88% of firm setting. This range allows for outstanding performance while still preserving aesthetics.

[0044] The resultant greige fabric produced on the loom 10 is either processed in a prepared for print form, or dyed, after scouring at 11. The print embodiment is illustrated schematically at 12 in FIG. 1 while the dyed embodiment is illustrated schematically at 13. For the print 12 routing, scouring at box 11 can be practiced on a jet, or on a continuous scouring range, the deciding factor being the desired suppleness. For maximum suppleness the fabric is processed on a jet at 11. If the fabric is processed in the dye routing 13, the fabric is preferably scoured at 11 on a continuous scouring range, and dyed at 13 using a conventional jet dyeing machine or the like. Regardless which of the details of the options 11-13 are selected, the fabric is heat set—as indicated at 14 in FIG. 1—utilizing conventional equipment at a minimum temperature of about 350° F. For the print option 12, heat setting at 14 preferably precedes printing, and for the dye option 13 preferably dyeing precedes heat setting at 14.

[0045] After the formation of the fabric is completed, as indicated by steps 10 through 14 (with optional additional processing steps being provided if desired), the fabric is then cut at 15, using conventional cutting equipment (either manual or automatic), and then is desirably formed into useful products for the hospitality market, such as curtains or bedspreads, as illustrated schematically at 16 in FIG. 1. Formation of the fabric into curtains or bedspreads is also conventional per se, conventional sewing machines and the like being utilized to form appropriate hems, pleats, stitching, or the like. The method also typically includes suggesting that the curtains be hung or the bedspreads be spread, as indicated at 17, and ultimately the end users will hang the curtains and spread the bedspreads, as indicated schematically at 18 in FIG. 1.

[0046] If the yarns are non-FR yarns and passage of NFPA701-96 is required, then the fabric produced from the yarns can be finished in a conventional manner with a conventional durable FR finish.

[0047] FIGS. 2 through 7 are microphotographs of various constructions of fabric according to the prior art, other attempts, and the invention. FIG. 2 shows the typical appearance of prior art all cotton staple spun yarn, having a degree of hairiness and non-uniformity, as illustrated schematically at 22. [The construction of FIG. 2 will hereinafter be referred to as style “III”.] FIG. 3 illustrates, as generally indicated by reference numeral 23, spun polyester (Trevira F/S), again a staple spun yarn with a certain degree of hairiness and non-uniformity.

[0048] FIG. 4 illustrates a 100% false twist filament product produced from Trevira FR, and illustrated schematically at reference numeral 24, and will be hereinafter referred to as style “V”. FIG. 5 illustrates schematically at reference numeral 25 another 100% false twist filament product and will be hereinafter referred to as style “VI”.

[0049] The 100% filament products produced with a combination of false twist and air textured yarns, as according to the present invention, are illustrated generally by reference numerals 26 and 27, respectively, in FIGS. 6 and 7. The particular construction 26 of FIG. 6 will be hereinafter referred to as style “I”, while the fabric 27 in FIG. 7 will be hereinafter referred to as style “II”.

[0050] FIG. 8 illustrates, schematically, a bedspread 31 made from a fabric like the fabric 26, 27, being formed in stages 15, 16 of FIG. 1 into a bedspread having hems 32 and stitching 33, and the like. FIG. 8 illustrates the bedspread 31 spread over a mattress 34, or other bed structure (e.g. box spring, bed board, etc.), the bedspread 31 being ideal for use in the hospitality market.

[0051] FIG. 9 schematically illustrates a curtain 40 produced from the fabric 26, 27. The curtain 40 is produced in steps 15, 16 of FIG. 1, and include appropriate stitching 41, pleats 42, and the like, and are hung by conventional mounting hardware illustrated schematically at 43 in FIG. 9. The curtains 40 cover, or are adjacent a transparent or translucent structural element, such as the window pane 44.

[0052] The fabrics 26, 27 according to the invention, and the bedspread 31 and curtains 40 constructed therefrom, may easily survive 50 commercial launderings with no wear or deterioration. These fabrics do not experience fuzzing and pilling during wear, like the staple spun yarn fabrics (such as the fabric 22, style III). While the fabrics 24, 25 (styles V and VI) have uniformly parallel orientation of the continuous filaments which do not significantly pill or fuzz, they do cause snagging (picking) in continued usage. The fabrics 26, 27 according to the present invention have none of the fuzzing, pilling, or snagging problems associated with the prior art constructions, and therefore are as close to indestructible as presently technically feasible, while still retaining excellent aesthetic properties.

[0053] The fabrics 26, 27, and the products 31, 40 made therefrom, according to the present invention score between about 4.5 and 5.0 on each of random tumble pilling, brush pilling, and Klopman method roughing and pilling, tests. Despite this excellent performance, the products have a surface SMD of at least about 4.3 microns (e.g. at least about 4.5 microns), a bending rigidity 2HB of about 0.1 or less (preferably about 0.09 or less), a compressibility EMC % of less than about 28 (e.g. about 25 or less), a shearing stiffness G value of about 2 or less (preferably about 1.5 or less), and an extensibility EMT % of at least about 3.0 (e.g. at least about 3.2).

[0054] For the purposes of understanding the tables which follow, and which indicate actual testing of the fabrics according to the invention compared to the prior art fabrics, yarn diameters, calculated pursuant to

	Yarn Diameter	1/150/60	:	156.0

		2/150/100	:	110.3
		2/150/100	:	90.1

[0055] Styles I, II, and VII in the following tables are pursuant to the invention, while styles III-VI are not according to the invention. The details of these styles (some of which have already been illustrated in FIGS. 2 through 7, as indicated above) are as follows:

[0056] The following table I illustrates the actual test results for the fabric styles according to the invention, compared with styles III-VI, using three different pilling tests. The random tumble pilling and brush pilling tests are standard industry tests. The brush pilling test, pursuant to ASTM D3511, determines the tendency of fabrics to form pills of fuzz under test conditions intended to simulate normal wear and utilizes a testing machine including two rotation platforms, nylon brushes mounted on a brush holder, and fabric specimens mounted on fabric specimen holders. The details of the test procedure are well known in the art.

[0057] The random tumble pilling test causes fabrics to form pills by a random rubbing motion produced by tumbling specimens in a cylindrical chamber lined with cork. Again the test procedures are well known.

[0058] The Klopman method roughing and pilling test is similar to the other tests only it adds sand paper to simulate maximum wear. Pills are formed on fabric by random rubbing motions produced by tumbling a sample in a cylindrical chamber lined with cork and flint paper, such as a Norton-Mohawk extra coarse flint paper 3 inches×5¾ inches and placed over a fresh cork liner.

[0059] In all of the test reports in table I, a score of 5.0 indicates excellent resistance (no pilling), a score of 4.0 indicates good resistance (slight pilling), a score of 3.0 medium resistance (moderate pilling), a score of 2.0 poor resistance (heavy pilling), and a score of 1.0 very poor resistance (very severe pilling). If a rating for a test specimen falls between two ratings a half value is assigned. Typically an average of three tests/ratings is given, although in some cases in table I all three test results are given rather than averaged. In the tests reported in table I all of the fabric styles were tested in the same way, with the same equipment, pursuant to the standard procedures for each of the tests involved.

[0060] Styles I through VI were also tested for aesthetic values (quantified values) using the Kawabata Evaluation System (KES). The KES is used for measuring mechanical hand properties. The KES instruments measure the mechanical properties that correspond to the fundamental deformation of fabrics in hand manipulation. Five different tests may be performed using KES, generating eighteen different mechanical characteristics. The details of all of the tests, for compression, surface, tensile, shearing stiffness, and bending rigidity, are standard, and the tests reported in table II were obtained by the North Carolina State University College of Textiles in Raleigh, N.C. using the KES equipment located there in 1997.

[0061] Styles A-C also are expected to have values substantially the same as those for styles I and III if similarly tested.

[0062] The test results reported in table II indicate that spun fabrics need up to twice the force to be compressed as do the fabrics according to the invention, resulting in more suppleness and drape of the fabrics according to the invention.

[0063] As far as surface roughness is concerned, the fabrics according to the present invention showed a slightly higher co-efficient of friction than the spun products and over a 100% rougher surface. This enhances bedspreads in reducing the movement (slippage) when on a bed, and improves seam slippage in fabricating either bedspreads or curtains.

[0064] The shearing tests provide a measure of stiffness and pliability. Products according to the invention are approximately three times more pliable than spun products, resulting in better draping of curtains and forming of bedspreads.

[0065] With respect to bending, the products according to the invention required one-third to 100% less force to bend. This further emphasizes the softness of hand and pliability of the fabrics according to the present invention compared to spun products.
