2. Description of Related Art

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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIG. 1, according to a first embodiment, a self-fastening fabric 1 is provided by the present invention, the self-fastening fabric 1 is a woven 3/1 warp-faced twill structure, warp yarns 11 a of the self-fastening fabric 1 at least include one thermoplastic-fiber yarn 111, weft yarns 12 a at least include one differential heat melting yarn 121. Wherein, a first surface 1 a of the 3/1 warp-faced twill structure is defined as a fibriform hook-like fabric structure 11, and a second surface 1 b thereof is defined as a micro-fibriform loop fabric structure 12. When being viewed from the first surface 1 a of the self-fastening fabric 1, the 3/1 warp-faced twill structure is shown, and the floating points of the warp yarns 11 a is three times the floating points of the weft yarns 12 a ; in this arrangement, the first surface 1 a is served as a fibriform hook-like fabric structure surface. As such, the area of the fibriform hook-like fabric structure 11 occupying the first surface 1 a is three times the area of the micro-fibriform loop fabric structure 12. Thus, after the 3/1 warp-faced twill structure is produced, most of the thermoplastic-fiber yarns 111 are shown on the first surface 1 a.
Referring to FIG. 2, which shows a rear surface of the self-fastening fabric shown in FIG. 1, in other words the second surface 1 b is shown; the second surface 1 b is a 3/1 weft-faced twill structure, the floating points of the weft yarns 12 a is three times the floating points of the warp yarns 11 a, the area where the micro-fibriform loop fabric structure 12 occupying the second surface 1 b is three times the area of the fibriform hook-like fabric structure 11; at this moment the second surface 1 b is served as a micro-fibriform loop fabric structure surface. Thus, after the 3/1 weft-faced twill structure is produced, most of the differential heat melting yarns 121 are shown on the second surface 1 b, so that the first surface 1 a and the second surface 1 b of the self-fastening fabric 1 are provided with an excellent mutual fastening function. Wherein, elastic fibers, for example polyurethane elastic fibers with the brand name of “LYCRA” or “OPELON” can be added in the warp yarn 11 a and the weft yarn 12 a, so that the self-fastening fabric 1 is provided with elasticity in the warp direction and/or weft direction.
Referring to FIG. 3, the warp yarn 11 a of the fibriform hook-like fabric structure 11 is made of the thermoplastic-fiber yarn 111. The thermoplastic-fiber yarn 111 can be selected from spun yarn from 10's to 80's, the thermoplastic staple fiber is cut from a polyester filament fiber having a proper length, the polyester filament fiber can be selected from 75de/72f, 150de/48f, 150de/36f or 450de/96f, the fiber size of the thermoplastic-fiber yarn 111 is between 1.04de/f to 4.69de/f, or smaller than 5de/f. As such, the thermoplastic staple fiber can be blended with a natural fiber for forming a blended spun yarn so as to provide various functions. In actual practice, the thermoplastic-fiber yarn 111 can be selected from polyester yarn, polyethylene yarn, polypropylene yarn, nylon yarn or polymethyl methacrylate yarn.
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 1 a 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 1 a, 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.
Referring to FIG. 4, the weft yarn 12 a of the micro-fibriform loop fabric structure 12 at least include one differential heat shrinking yarn 121, the differential heat shrinking yarn 121 includes a first fiber 123 having a first heat shrinking rate, for example selected from 30de/12f polyester having a heat shrinking rate greater than 15%, and a second fiber 124 having a second heat shrinking rate, for example selected from 50de/114f polyester having a heat shrinking rate at about 3%, the first heat shrinking rate is greater than the second heat shrinking rate, so the difference between the heat shrinking rates of the first fiber 123 and the second fiber 124 is preferably to be greater than 7%. The mixed-shrinkage yarn 121 is processed with a heat shrinking process, for example the high temperature during a dyeing process, thus the mixed-shrinkage yarn 121 would generate different heat shrinking rates which causes the second fiber 124 to be longer than the first fiber 123, thereby enabling the micro-fibriform loop fabric structure 12 to be formed with the plural micro-fibriform loops in the fluffy status.
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 12 a 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 FIG. 5, the self-fastening fabric 1 is applied as a rectangular wrapping fabric; when being used for wrapping an object, the first surface 1 a and the second surface 1 b of the self-fastening fabric 1 are mutually fastened, so the means for tying knots for a convention wrapping fabric is not required so as to avoid the existence of the knots, thus effects of being more convenient in use and increasing the wrapping space of the wrapping fabric are provided. In addition, with the mutual fastening function provided by the first surface 1 a and the second surface 1 b of the self-fastening fabric 1, a wrapping tape used in boxing can be prevent from being loosened while being wrapped so as to provide a better efficiency, or the length of the wrapping tape can be shortened for greatly improving the wrapping speed and quality.
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 11 a being shown on the second surface 1 b, meanwhile there are more of the weft yarns 12 a being shown on the first surface 1 a. In other words, the amount of the fibriform hook-like fabric structure 11 on the first surface 1 a is decreased, and the amount of the micro-fibriform loop fabric structure 12 on the second surface 1 b 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 FIG. 6, the 5-end warp-flush satin is adopted for forming the self-fastening fabric 1.
As mentioned above and what has been shown from FIG. 1 to FIG. 4 and FIG. 6, the self-fastening fabric 1 is at least formed by one micro-fibriform loop fabric structure 12 and one fibriform hook-like fabric structure 11, the self-fastening fabric 1 has the first surface 1 a and the second surface 1 b, both of the first surface 1 a and the second surface 1 b have the micro-fibriform loop fabric structure 12 and the fibriform hook-like fabric structure 11, the area of the micro-fibriform loop fabric structure 12 on the first surface 1 a is set to be a determined multiple of the area of the fibriform hook-like fabric structure 11, and the area of the fibriform hook-like fabric structure 11 on the second surface 1 b is the above-mentioned determined multiple of the micro-fibriform loop fabric structure 12, and the determined multiple is greater than or equal to two.
Fibers contained in the micro-fibriform loop fabric structure 12 includes at least one kind of the mixed-shrinkage yarn 121, and the micro-fibriform loop fabric structure 12 is processed with a heat shrinking process for forming the plural micro-fibriform loops 122. Fibers contained in the fibriform hook-like fabric structure 11 includes at least one kind of the thermoplastic-fiber yarn 111, and if the fibriform hook-like fabric structure 11 is composed of the thermoplastic filament yarn, a peach finishing is required to be processed for allowing the surface of the fibriform hook-like fabric structure 11 to be formed with hairiness, then a singeing process is processed for forming the plural restraining fibers 112 respectively having the curved shape 113 and/or the bead distal end 114. If the fibriform hook-like fabric structure 11 is composed of the thermoplastic-fiber spun yam, the surface of the fibriform hook-like fabric structure 11 has already been formed with the hairiness, thus only the singeing process is required for forming the plural restraining fibers 112 respectively having the curved shape 113 and/or the bead distal end 114.
When the micro-fibriform loop fabric structure 12 on the first surface 1 a and the fibriform hook-like fabric structure 11 on the second surface 1 b are in contact, the micro-fibriform loops 122 and the restraining fibers 112 are mutually hooked or tangled, so that a fastening effect is formed between the first surface 1 a and the second surface 1 b.
Referring to FIG. 7, which discloses a second embodiment of the self-fastening fabric provided by the present invention, the self-fastening fabric 1 is a variation of the interlock double-face based structure, a first surface 1 a of the self-fastening fabric 1 is served as a fibriform hook-like fabric structure 11 and includes a thermoplastic-fiber yarns 111. A second surface 1 b of the self-fastening fabric 1 is served as a micro-fibriform loop fabric structure 12 and includes mixed-shrinkage yams 121.
A plurality of connection points of the first surface 1 a and the second surface 1 b are formed for fabricating the self-fastening fabric 1. The connection points are respectively formed with a recess on the first surface 1 a, and the connection points are hidden in the recesses, so that the first surface 1 a is fully provided with the fibriform hook-like fabric structure 11, and the second surface 1 b is fully provided with the micro-fibriform loop fabric structure 12, or vice versa. With the variation of the interlock double-face based structure, the first surface 1 a can be fully provided with the fibriform hook-like fabric structure 11, and the second surface 1 b can be fully provided with the micro-fibriform loop fabric structure 12.
According to the second embodiment, the fibriform pile fabric structure 11 can be composed of the thermoplastic-fiber spun yarn or the thermoplastic filament yarn, if the fiber contained in the fibriform hook-like fabric structure 11 is the thermoplastic-fiber spun yarn, only a singeing process is required for allowing the restraining fibers 112 having the thermoplastic-fiber spun yarn to be respectively formed in the curved shape 113 and/or formed with the bead distal end 114. If the fiber contained in the fibriform thermoplastic-fiber fabric structure 11 is selected from the thermoplastic filament yarn, the first surface 1 a is required to be processed with a peach finishing and a singeing process for allowing the plural restraining fibers 112 having the curved shape 113 and/or the bead distal end 114 to be formed. After a heat shrinking process, the micro-fibriform loop fabric structure 12 composed of the mixed-shrinkage yarn 121 of the second surface 1 b is formed with plural micro-fibriform loops 122, so that the first surface 1 a and the second surface 1 b 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.
Referring to FIG. 8, which disclosed a third embodiment of the self-fastening fabric provided by the present invention, the self-fastening fabric 1 is a plated jersey fabric, the knitted fabric is formed through stacking a mixed-shrinkage yarn 121 and a thermoplastic-fiber yarn 111 then being knitted by a single jersey knitting machine. If the thermoplastic-fiber yarns 111 of the fibriform hook-like fabric structure 11 are shown in the first surface 1 a, the mixed-shrinkage yarns 121 of the micro-fibriform loop fabric structure 12 are shown on the second surface 1 b, or vice versa. According to this embodiment, the first surface 1 a is fully provided with the micro-fibriform loop fabric structure 12, and the second surface 1 b is fully provided with the fibriform hook-like fabric structure 11.
As mentioned above, the fiber contained in the fibriform hook-like fabric structure 11 of the first surface 1 a can be the thermoplastic-fiber spun yarn or the thermoplastic filament yarn, if the thermoplastic-fiber spun yarn is adopted, only the singeing process is required for allowing 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. If the fiber contained in the fibriform hook-like fabric structure 11 is selected from the thermoplastic filament yarn, the first surface 1 a is required to be processed with the peach finishing and the singeing process for forming the plural restraining fibers 112 having the curved shape 113 and/or the bead distal end 114. After the heat shrinking process, the micro-fibriform loop fabric structure 12 composed of the mixed-shrinkage yarn 121 of the second surface 1 b is formed with the plural micro-fibriform loops 122, so that the first surface 1 a and the second surface 1 b 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 for being provided with the mutual fastening effect.
Referring to FIG. 9, which discloses a fourth embodiment of the self-fastening fabric provided by the present invention, the self-fastening fabric 1 is a spacer fabric. The fiber contained in the fibriform hook-like fabric structure 11 of the first surface 1 a of the spacer fabric include a thermoplastic-fiber spun yarn or a thermoplastic filament yarn. The fiber contained in the micro-fibriform loop fabric structure 12 of the second surface 1 b is a mixed-shrinkage yarn 121. The first surface 1 a and the second surface 1 b are connected by a connection yarn 125 for forming the spacer fabric. The connection yarn 125 is selected from mono-filament, filament yarn or spun yarn. The composed yarns of the first surface 1 a and the composed yarns of the second surface 1 b of the spacer fabric formed by the above-mentioned means do not have direct connections points, thus the first surface 1 a can be fully provided with the fibriform hook-like fabric structure 11, and the second surface 1 b can be fully provided with the micro-fibriform loop fabric structure 12; with the above-mentioned treatment process, the first surface 1 a and the second surface 1 b of the self-fastening fabric 1 are respectively served as the fibriform hook-like fabric structure 11 and the micro-fibriform loop fabric structure 12, and a mutual fastening function is provided.
The connection yarn of the spacer fabric can be selected from nylon mono-filament with 30de/1f, so that a space is formed between the first surface 1 a and the second surface 1 b of the spacer fabric, thereby providing functions of insulation and shock absorption. In addition, it is known that the connection yarn can be a conventional textured filament yarn for reducing thickness.
Moreover, the first surface and the second surface of the self-fastening fabric 1 is a single-faced structure, or single-faced jacquard structure for allowing the self-fastening fabric 1 to be provided with patterns and colors.
