The present invention relates to a self-fastening fabric, especially to a fabric having a first surface and a second surface being provided with a mutual fastening function.
Taiwan Pat. No. 1388291 (equivalent to U.S. Pat. No. 8,551,596) granted to the applicant of the present invention has disclosed a conventional self-sticking fabric; the self-sticking fabric comprises a hook fabric structure and a loop fabric structure, the loop fabric structure is formed through a composite yarn being woven then processed with a splitting treatment for being decomposed so as to form more ultra microfibers, and loop-like fastening elements are respectively formed between two interlacing points of the yarn; and the hook fabric structure is composed of a heat melting synthetic short yarns, and formed as a mixed fabric through being mixed with micro-fiber yarn by utilizing a shuttle loom or a knitting machine, and processed by a singeing treatment to make the fine hairs of the synthetic short fibers formed with bead distal ends, and thereby form hook-like fastening elements corresponding to the loop-like fastening elements for the purpose of fastening.
However, in actual practice, as the loop fabric structure is used for being tangled with the corresponding hook fabric structure to generate a fastening effect, the fluffy status of the loop-like fastening elements of the loop fabric structure will greatly determine the fastening effect of the sticking fabric. If there is no other fibers with different heat shrinking rates being formed after the composite yarn being processed with the splitting treatment, the surface of the loop fabric structure will be only formed as a flat compact fabric without fluffy loop-like fastening elements thereon, and the fastening effect will be quite limited.
Moreover, if the weight of the heat melting short yarn contained in the hook fabric structure is less than 50%, the restraining fibers remained after the non-heat melting fibers burn out in the singeing treatment can only offer a poor fastening effect.

The fibriform hook-like fabric structure 11 is treated with a singeing process, so that restraining fibers 112 having the thermoplastic staple fiber are respectively formed in a curved shape 113 and/or formed with a bead distal end 114. The natural fibers would be burn out during the singeing process, and only the restraining fibers 112 formed by the thermoplastic staple fibers are remained, thus the weight of thermoplastic staple fibers is preferably to be more than 50% of the fibriform hook-like fabric structure 11, such as the blended spun yarn, so sufficient amount of the restraining fibers 112 can be provided. The thermoplastic staple fiber can be selected from polyester, polyamide, polyolefin or polyacrylonitrile. According to this embodiment, the surface of the fibriform hook-like fabric structure 11 is formed with hairiness, the hairiness would be naturally protruded from the surface of the thermoplastic-fiber yarn 111 by ring spinning process, wherein in actual practice, the thermoplastic-fiber yarn 111 is preferably to be a ring spun yarn, the reason is that the amount of hairiness of the ring spun yarn is relatively greater, so that the fibriform hook-like fabric structure 11 made of the ring spun yarn is provided with a better fastening effect. The thermoplastic-fiber yarn 111 can also be selected from textured filament yarn, for example 75de/72f, 150de/48f, 150de/36f or 450de/96f. The fiber size of the textured filament yarn is between 1.04de/f to 4.69de/f, or smaller than 5de/f. The textured filament yarn can be selected from polyester, polyamide, polyolefin or polyacrylonitrile.
Because the textured filament yarn without hairiness on the surface, the first surface 1a where the fibriform hook-like fabric structure 11 occupying a greater area is treat with a peach finishing for being peached, so that a part of the fibers on the surface of the fibriform hook-like fabric structure 11 are worn out for generating the plural restraining fibers 112 in a thick hairiness status, thus the restraining fibers 112 are all shown on the first surface 1a, then the singeing process is processed for enabling the restraining fibers 112 having the thermoplastic-fiber to be respectively formed in the curved shape 113 and/or formed with the bead distal end 114.
According to this embodiment, the hairiness is formed by the peach finishing, so the hairiness is only shown on the surface of the fibriform hook-like fabric structure 11 where the peach finishing is processed, therefore the amount and the length of the hairiness can be selected through adjusting the duration of the peach finishing, the types of brushes or sandpapers, and the fibriform hook-like fabric structure 11 having different fastening strength can be formed for satisfying various product requirements .
The fiber size of the thermoplastic-fiber is selected from 1.04de/f to 4.69de/f, or smaller than 5de/f, for being corresponding to the dimension of micro-fibriform loops 122 of the micro-fibriform loop fabric structure 12, thereby enabling an optimal mutual tangling function to be generated, but what shall be addressed is that the fiber size is not limited to the above-mentioned arrangement. Wherein, the thermoplastic-fiber can be formed with plural micro pores and/or having hollow inner chamber for enlarging the surface area, so that the fibriform hook-like fabric structure 11 is provided with functions of moisture wicking and quick drying. In addition, the thermoplastic-fiber yarn 111 can be further treated with a hygiene finishing or blended with a silver-coated fiber, so that the fibriform hook-like fabric structure 11 is provided with an antibacterial function. Moreover, the thermoplastic-fiber yarn 111 can be further blended with a metal fiber, such as silver-coated fiber, copper fiber or grapheme fiber, so that functions of antistatic and electrically conducting are provided. Furthermore, the thermoplastic-fiber yarn 111 can be added with the above-mentioned elastic fibers for being provided with elasticity.

According to this embodiment, the self-fastening fabric is shrunk due to the heat in the dyeing process, then the weft width of the self-fastening fabric 1 is stretched in a following heat setting process, thereby allowing the proper differentiation of the shrinking rates between the first fiber 123 and the second fiber 124 to be adjusted then to be set, so that the fluffy level of the micro-fibriform loops 122 can be adjusted again. The first heat shrinking rate of the first fiber 123 is provided with a high heat shrinking rate through modifying the crystalized polyester, the modifying means is a prior art in the field of the present invention, therefore no further illustration is provided. If the 50de/114f polyester fiber is adopted as the second fiber 124, the fiber size is about 0.347de/f, which is thicker than the fiber formed through a complex conjugate fiber being processed with a splitting process, the second fiber 124 is not required to be processed with a complex conjugate spinning process, so that a splitting process is also not required, thereby simplifying the production procedure and increasing the durability.
The second fiber 124 of the mixed-shrinkage yarn 121 can be selected from polyester complex conjugate fibers such as segmented pie 80de/72x12f (PET/Co-PET) or sea-island 75de/24x37f. The first fiber 123 is for example selected from fibers 30de/12f having a high heat shrinking rate, and the second fibers 124 are selected from complex conjugate fibers processed with a chemical splitting process with alkaline solution, so that the polyester complex conjugate fiber yarn is split from 1.11de/f to 0.09de/f micro-fibers theory, and the fiber numbers of the micro-fiber is 12 times the complex conjugate fiber before splitting; and the mixed-shrinkage yarn 121 generates different heat shrinking rates through the high temperature in the chemical splitting process and/or the dyeing process, thus the second fiber 124 is longer than the first fiber 123, and the micro-fibriform loop fabric structure 12 is formed with the plural micro-fibriform loops 122 in the fluffy status. As such, with the thinner yarn, for example the polyester complex conjugate fiber yarn, being adopted as the micro-fibriform loop fabric structure 12, the fabric is suitable to be applied in thin and soft fabric structure. Thus, if the complex conjugate fiber is adopted as the second fiber 124, the fiber size is smaller than 0.3 denier, and the chemical splitting process can be processed if necessary, so that the complex conjugate fiber can be split for forming more microfibers in numbers.
According to the self-fastening fabric disposed in the first embodiment, the size of the restraining fiber 112 is selected from 1 de to 5 de, and the size of the micro-fibriform loop 122 is selected from 0.08 de to 2.0 de; the size difference between the above two fibers becomes greater, the mutual fastening effect becomes easier to be achieved, however the durability is in a reverse ratio relative to the fiber fineness, for example the preferable combination is that the restraining fiber 112 with 150de/48f matching with the micro-fibriform loop 122 with 50de/144f, or the restraining fiber 112 with 75de/36f matching with the micro-fibriform loop 122 with 80de/72x12f, but what shall be addressed is that the scope of the present invention is not limited to the above-mentioned arrangement. Moreover, the mixed-shrinkage yarn 121 can also be added with the above-mentioned elastic fibers, so that the mixed-shrinkage yarn 121 is provided with elasticity.
Because the first fiber 123 is able to generate a greater shrinkage during the dyeing process, and the distance defined between two adjacent interlacing points can be shortened, the heat shrinkage of the second fiber 124 is relatively much smaller, so that a loosened floating yarn is formed between two adjacent interlacing points of the weft yarn 12a of the second fiber 124, thereby allowing the micro-fibriform loops 122 in the fluffy status to be formed. The complex conjugate yarn can also be processed with an co-extruding spinning means with polyester and polyamide (PET/PA6), so that the polyester and the polyamide can coexist in the fiber after being processed with the splitting process; the difference between the heat shrinking rates of the first fiber 123 and the second fiber 124 having two different heat shrinking rates is preferably to be greater than 7%. If the mixed-shrinkage yarn 121 of the micro-fibriform loop fabric structure 12 is added with the first fiber 123 having a higher heat shrinking rate, the self-fastening fabric 1 would become thicker which can be applied as a scarf having a self-fastening function for the purpose of keeping warm.
Referring to
In actual practice, a 2/1 warp-faced twill structure, 4/1 warp-faced twill structure and 5-end warp-flush satin structure can be adopted as the self-fastening fabric 1, the floating point ratios of the above-mentioned structures are respectively two times, four times and five times, the occupied areas are respectively two times, four times and five times; the floating point ratio becomes greater, the crossing distance of the floating yarn becomes larger, so that the fabric 1 is softer, the micro-fibriform loops 122 are longer, but the restraining fibers 112 of the fibriform hook-like fabric structure 11 would become relatively soft and fluffy. As such, the 2/1 warp-faced twill structure having smaller floating points not only has floating yarn with smaller crossing distance, there are more of the warp yarns 11a being shown on the second surface 1b, meanwhile there are more of the weft yarns 12a being shown on the first surface 1a. In other words, the amount of the fibriform hook-like fabric structure 11 on the first surface 1a is decreased, and the amount of the micro-fibriform loop fabric structure 12 on the second surface 1b is also decreased, thus the mutual fastening function is lowered. Accordingly, the 3/1 warp twill structure, the 4/1 warp twill structure and the 5-end satin structure are preferably to be adopted. Referring to

After a heat shrinking process, the micro-fibriform loop fabric structure 12 composed of the mixed-shrinkage yarn 121 of the second surface 1b is formed with plural micro-fibriform loops 122, so that the first surface 1a and the second surface 1b of the self-fastening fabric 1 are respectively formed as the fibriform hook-like fabric structure 11 and the micro-fibriform loop fabric structure 12 so as to be provided with a mutual fastening effect.
