The present invention relates to fabricating fabrics; more particularly, relates to uniformly mixing a pigment and an antimicrobial agent into yarns to fabricate iodine-based-antimicrobial colored fabrics for significantly reducing waste water pollution from dyeing and processing and avoiding skin allergies.
Fabrics made of antimicrobial fiber yarns can prevent skin diseases with antibacterial, antiseptic, deodorant and anti-mildew functions in a very comfortable wear. For providing the antimicrobial function in the yarns, an antimicrobial agent can be mixed into solution for spinning; pores can be narrowed; physical and/or chemical characteristics can be modified; fibers mixed for making fabrics can be changed; or, methods for dyeing and coating can be refined. Therein, the most common choice is to mix an antimicrobial agent into solution for spinning, where silver-based antimicrobial agent is the most commonly used. However, silver element contained in the silver-based antimicrobial agent can cause skin irritation, tissue damage and other issues. Hence, the prior art does not fulfill all users' requests on actual use.
The main purpose of the present invention is to provide an apparatus for binding a pigment, an antimicrobial agent (comprising an iodine-containing compound and zinc oxide), a dispersant and a related polymer substrate carrier to fabricate iodine-based-antimicrobial colored masterbatches; and spinning the masterbatches into yarns for uniformly mixing the pigment and the antimicrobial agent into fabric to fabricate iodine-based-antimicrobial odor-absorbing colored fabrics, where waste water pollution from dyeing and processing is significantly reduced and skin allergies are avoided.
To achieve the above purpose, the present invention is an apparatus of fabricating iodine-based-antimicrobial colored fabrics, comprising a masterbatch generator, a plurality of masterbatches, a drying device, a yarn spinner, a first fabric generator and a second fabric generator, where the masterbatch generator melt-kneads a raw material to be extruded into masterbatches through cooling and granulating; the masterbatches are fabricated from the masterbatch generator; the masterbatches are iodine-based-antimicrobial and colored; the drying device is connected to the masterbatch generator; the drying device hot-dries the masterbatches to form a plurality of dried masterbatches; the yarn spinner is connected to the drying device to fabricate yarns by spinning; the yarns are iodine-based-antimicrobial, odor-absorbing and colored; the first fabric generator is connected to the yarn spinner to fabricate an iodine-based-antimicrobial colored fabric, like a knitted fabric, a woven fabric or a plush fabric; and the second fabric generator is connected to the drying device to fabricate an iodine-based-antimicrobial colored non-woven fabric. Accordingly, a novel apparatus of fabricating iodine-based-antimicrobial colored fabrics is obtained.
The present invention will be better understood from the following detailed description of the preferred embodiment according to the present invention, taken in conjunction with the accompanying drawing, in which
The following description of the preferred embodiment is provided to understand the features and the structures of the present invention.
Please refer to
The masterbatch generator 1 comprises a mixing unit 11; a high-speed powder kneading device 12 communicated with the mixing unit 11; a driving unit 13 located at a side of and connected to the powder kneading device 12; a cooling tank 14 located at another side of and connected to the powder kneading device 12; a granulator 15 located at a side of and connected to the cooling tank 14; and a collecting trough 16 located at another side of and connected to the cooling tank 14. The masterbatch generator 1 processes kneading and melt-blowing to a raw material; and, after being melted and kneaded, the raw material is extruded to fabricate a plurality of iodine-based-antimicrobial colored masterbatches 6a through cooling and granulating.
The drying device 2 is connected to the collecting trough 16 of the masterbatch generator 1 to hot-dry the masterbatches 6a for forming a plurality of dried masterbatches 6.
The yarn spinner 3 is connected to the drying device 2 and comprises a yarn-making device 31; a winding device 32 corresponding to the yarn-making device 31 at an end; and a plurality of rollers 33 located between the yarn-making device 31 and the winding device 32. The yarn spinner 3 fabricates iodine-based-antimicrobial odor-absorbing colored yarns through spinning.
The first fabric generator 4 is connected to the yarn spinner 3 to fabricate an iodine-based-antimicrobial colored fabric, such as a knitted fabric, a woven fabric, a plush fabric, etc.
The second fabric generator 5 is connected to the drying device 2 to fabricate an iodine-based-antimicrobial colored non-woven fabric.
Thus, a novel apparatus of fabricating iodine-based-antimicrobial colored fabrics is obtained.
Each of the masterbatches 6 comprises 40˜69.5 weight percents (wt %) of a polymer substrate carrier 61; 0.01˜6 wt % of a dispersant 62; 1˜30 wt % of a antimicrobial agent 63; and 1˜30 wt % of a pigment 64. The polymer substrate carrier 61 is made of poly(trimethylene terephthalate) (PTT), polybutylene terephthalate (PBT), polyethylene terephthalate (PET), polypropylene (PP), polyethylene (PE), Nylon 6, Nylon 6,12, Nylon 6,6 or a mixture thereof. The antimicrobial agent comprises an iodine-containing compound and zinc oxide and the iodine-containing compound is povidone-iodine.
On fabricating the masterbatches 6, the polymer substrate carrier 61, the dispersant 62, the antimicrobial agent 63 and the pigment 64 are put in the mixing unit 11 of the masterbatch generator 1 to be mixed by a high-speed powder kneading device 12 at a rotational speed of 1000 rotations per minute (RPM)˜3000 RPM for a time of 10˜90 minutes. Thus, the antimicrobial agent 63 is quickly and uniformly dispersed in a polymer-substrate-carrier mixture for forming a polymer-substrate powder having the antimicrobial agent 63 and the pigment 64 uniformly dispersed. Therein, the polymer-substrate powder is kneaded and granulated at a temperature of 220 Celsius degrees (° C.)˜300° C. by a twin-screw kneading device having a screwing speed of 300 RPM˜400 RPM with coordination of the cooling tank 14 and the granulator 15 for fabricating iodine-based-antimicrobial colored masterbatches 6a having the antimicrobial agent 63 uniformly dispersed. Then, the fabricated iodine-based-antimicrobial colored masterbatches 6a are collected in the collecting trough 16 to be hot-dried by the drying device 2 at a temperature of 110° C.˜140° for 6˜30 hours for forming the dried masterbatches 6.
On fabricating the iodine-based-antimicrobial colored yarns, 1˜20 wt % of the dried masterbatches 6 are put into the yarn-making device 31 of the yarn spinner 3 to be spun with coordination of spinning nozzle 7 for fabricating the iodine-based-antimicrobial colored yarns 8a having yarn finenesses of 1˜100 deniers; and, then, the iodine-based-antimicrobial colored yarns 8a are winded by the winding device 32 through the rollers 33. Furthermore, by using the iodine-based-antimicrobial colored yarns 8a for fabricating a fabric (i.e. a cloth), an iodine-based-antimicrobial colored fabric 8 like a knitted fabric, a woven fabric or a plush fabric is fabricated through the first fabric generator 4.
Or, the second fabric generator 5 can melt-knead the 1˜20 wt % dried masterbatches 6 to fabricate an iodine-based-antimicrobial colored fabric non-woven fabric 9.
Hence, the present invention binds a pigment, an antimicrobial agent (comprising an iodine-containing compound and zinc oxide), a dispersant and a related polymer substrate carrier to fabricate iodine-based-antimicrobial colored masterbatches. Then, the masterbatches are spun into yarns for uniformly mixing the pigment and the antimicrobial agent into fabric to fabricate iodine-based-antimicrobial odor-absorbing colored fabrics, where waste water pollution from dyeing and processing is significantly reduced and skin allergies are avoided.
To sum up, the present invention is an apparatus of fabricating iodine-based-antimicrobial colored fabrics, where a pigment, an antimicrobial agent, a dispersant and a related polymer substrate carrier are bond to fabricate iodine-based-antimicrobial colored masterbatches; the masterbatches are spun into yarns for uniformly mixing the pigment and the antimicrobial agent into fabric; and, thus, iodine-based-antimicrobial odor-absorbing colored fabrics are fabricated for significantly reducing waste water pollution from dyeing and processing and avoiding skin allergies.
