TITLE: STRUCTURE OF TOUCH-FASTENING ANTI-SKIDDING rot III (a) Technical Field of the Invention I OF
The present invention generally relates to a novel design of structure of oo touch-fastening anti-skidding material, which has the features of being fit for mass production and manufacture of large width surface area, flexibility, resiliency, and light weight, and also offers the advantages of high air permeability and low manufacturing costs, and is fit for combination with other materials and suitable for being bonded to various felts/rugs, flannelette, loop cloth (terrycloth) to realize touch-fastening and anti-skidding. (b) Description of the Prior Art
The commonly known touch-fastener straps or hook-and-loop (Velcro) straps have the features of touch-fastening and anti-skidding. The known hook-and-loop strap is often composed of a male hook band and a female loop band. The male hook band has a surface forming a felt-like face on which a plurality of projecting hooks that has ends forming hooks is uniformly distributed. The female loop band has a surface forming a velvet-like face on which curled and entangling yarns are uniformly distributed. When the male and female bands are put together to have the felt-like face and the velvet-like faces thereof touching each other, the hooks of the felt-like face largely engage the curled and entangling yarns so as to fix the bands together. The known structure of the touch-fastener strap is effective in fixing articles to be fastened together, but the conventional touch-fastener strap suffers high manufacturing costs and difficulty in making large width products, and is only fit for a continuous manufacture of small-surface-area elongate straps, making the "production performance very poor. Further, the conventional touch-fastener strap is generally not pliable, making it difficult to bond to articles or materials showing a three-dimensional configuration. To overcome such problems, the present invention aims to provide a unique touch-fastening material, which can be manufactured by weaving synthetic fibers/yams of different characteristics or synthetic fibers/yarns of different diameter sizes in order to suit the needs of different applications, wherein the length of the synthetic fibers/yarns used can be set according to the processing needed. The yarns are woven to form a foundation layer that can be a net cloth having hollow opening sections (see FIG 1 of the attached drawings) or a net cloth having no hollow opening sections (see FIG 7). When the net cloth so woven having hollow opening sections, the hollow opening sections can assume various shapes, such as circle, honeycomb, quadrangle, and other geometric shapes.
The formation of the hollow opening sections provides the anti-skidding material with enhanced resiliency for stretchability and deformation in both length and width and improved air permeability. This also offers an advantageous feature of enhanced shapeability for forming a three-dimensional configuration for surface-bonding to other materials that may show three-dimensional configurations. Since the synthetic fibers/yams are woven in the foundation layer, all the synthetic yarns are tightly secured together without undesired separation off and thus additional adhesive layer applied to the bottom thereof for bonding purposes is not necessary. This makes the material of the present invention advantageous in view of manufacturing costs. The touch-fastening material of the present invention : may also be subjected to additional processing by passing through a tunnel-shape oven, in which ends of the fibers/yarns are melt and form hooks with rounded end. The touch-fastening material of the present invention provides excellent resistance against skidding and thus offers extremely wide applications for anti-skidding material in various industries.
Thus, the present invention aims to provide a mass-productive, light-weighted, air-permeable, resiliently expandable, and structure simplified anti-skidding material that provides effective skidding resistance for various material, including felts/rugs, flannelette, and loop cloth (terrycloth).
The primary objective of the present invention is to provide a structure of touch-fastening material, which provides an anti-skidding formed by weaving, whereby the anti-skidding material is flexible and resilient, and which is formed by weaving two types of fibers/yarns of different materials and synthetic fibers/yams together so that a woven foundation layer is formed and comprises a great number of synthetic fibers/yarns extending therein and the anti-skidding material can be manufactured in a mass production manner with excellent features of light-weight, air permeability, resilience, and processability.
Another objective of the present invention is to provide an anti-skidding material, which possesses excellent stretchability and flexibility that offers excellent characteristics of being easily applied to a three-dimensional surface so that the anti-skidding material can be easily shaped for forming an excellent bonding surface for three-dimensional configuration.
A further objective of the present invention is to provide a touch-fastening anti-skidding material that is applicable to felts/rugs, flannelette, and loop cloth (terrycloth) for anti-skidding purposes.
To achieve the above objectives, the present invention provides a touch-fastening anti-skidding material, which comprises a woven foundation layer and a plurality of synthetic fibers/yarns that is collectively woven in the foundation layer and secured together. The woven foundation layer is formed by collectively weaving two strands of pliable base yarns and synthetic yarns and allowing the synthetic yarns to extend beyond the woven foundation layer by a given distance. The synthetic yarns possess predetermined rigidity strength, which makes the foundation layer an underside cloth that is flexible, resilient, and light-weighted, whereby when bonded to felts/rugs, flannelette, and loop cloth (terrycloth), the anti-skidding material of the present invention provides excellent resistance against skidding,
The foregoing objectives and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings.

Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
Reference is now made to FIGS. 1, 1A, and 2, in which FIG 1 isa perspective view of a touch-fastening anti-skidding material in accordance with the present invention, FIG 1A is an enlarged view of a portion of the touch-fastening anti-skidding material, and FIG 2 is a schematic view showing a foundation layer and synthetic yarns woven together in accordance with the present invention. As shown, the touch-fastening anti-skidding material in accordance with the present invention, generally designated at 10, comprises a plurality of synthetic yams 20a, 20b and pliable base yarns 30a, 30b.
C
Also referring to FIGS. 3-5, each synthetic yarn 20a, 20b is bent to form a U-shaped configuration, having a loop 21 (see FIG 3) and two outward-extending short legs 22 (see FIG 3). Each rear loop 21 loops around each front loop 21 so that the loops 21 are linked together with the short legs 22 that are located at ends of the loops 21 and of a predetermined length extending outside a foundation layer 40. The synthetic yarns 20a, 20b are accompanied by the pliable base yarns 30a, 30b in an alternate manner in the front-rear direction (see FIGS. 3 and 4) so that the first synthetic yarns 20a is combined with the base yarn 30a, while the second synthetic yarn 20a that is linked to the first synthetic yarn 20a is combined with the base yarn 30b.
Similarly, the first synthetic yarn 20b is combined with the base yarn 30b, while the second synthetic yarn 20b that is linked to the first synthetic yarn 20b is combined with the base yarn 30a. In this way, two strands are collectively woven in a dual yarn manner to form a woven strand A (as shown inFIG 1A). The synthetic yarns 20a, 20b and the base yarns 30a, 30b are collectively woven on a common horizontal plane and form a foundation layer 40. The base yarns 30a, 30b that are arranged to parallel accompany the synthetic yarns 20a, 20b are arranged in such a way that the base yarns 30a, 30b, after co-bent with the synthetic yarn to form the loops 21, are allowed to individually and transversely extend to and subsequently parallel accompany the synthetic yarn 20a, 20b of an adjacent strand (see FIGS. 3 and 4). The synthetic yarns 20a, 20b can be made of nylon plastics, or polyesters, or polypropylene (PP) plastics, or polyethylene (PE) plastics.
® 22010700454
As shown in FIGS. 3-6, the base yarn 30a, which is arranged to co-extend with the synthetic yarn 20a form a loop, is allowed to extend transversely to the synthetic yarn 20b of the adjacent strand for subsequently co-extending with the synthetic yarn 20b for dual yarn weaving, so that the synthetic yams 20a, 20b and the base yarns 30a, 30b are woven in a common horizontal plane to form the foundation layer 40. The foundation layer fabric comprises loops 21 of the synthetic yarns 20a, 20b linked to each other in the front-rear direction, so that the rear one of the loops is set to loop around the front one of the loops and each of the linked loops 21 has ends that form short legs 22 of predetermined length extending outside the foundation layer 40.
When the transversely extending base yarns are of great lengths, the lengths of the base yarns allows for formation of gaps X that define hollow openings, whereby the foundation layer 40 is provided with hollow opening sections, which can be of any desired shape, such as circle, honeycomb, quadrangle, and other geometric shapes. The presence of the hollow opening sections helps improving stretchability and deformability in the longitudinal direction and the transversely direction.
As shown in FIG 7, the present invention provides a touch-fastening anti-skidding material 10a, which comprises a large area cloth formed by weaving of the foundation layer 40 in an expanded manner, wherein the base yarns 30a, 30b that are woven in the foundation layer to extend transversely in the planar surface of the cloth are arranged in a tightened manner so that no gaps X that form hollow openings are formed by excessive length of the base yarns 30a, 30b. And, in this way, a planar touch-fastening anti-skidding material 10a is formed.
Further referring to FIGS. 8 and 9, a further feature of the present invention is provided, wherein the touch-fastening material of the present invention, after being formed by collectively weaving the synthetic yarns 20a, 20b and the base yarns 30a, 30b, is further processed by passing through a tunnel-type oven for heating, whereby free ends of the legs 22 of each synthetic yam 20a, 20b are fused to form rounded ends 23 (see FIG 8).
Alternatively, the free ends of the legs of each synthetic yarn 20a, 20b is subjected to heating and compressed to form hooks 24 (see FIG. 9). The short legs 22 of synthetic yarns extending beyond the surface of cloth so formed by weaving are set to project outside the foundation layer and the distance or length of the legs 22 of the synthetic yarns 20a, 20b can be adjusted as desired, and the synthetic yarns shows rigidity strength.
Thus, the touch-fastening anti-skidding material in accordance with the present invention possesses advantages of light weight, high air permeability, and flexibility and is fit for mass production of large width products.
To summarize, the present invention provides a touch-fastening anti-skidding material that is structured by having synthetic yarns of short lengths woven together with the cloth that forms a foundation layer to provide the effect of anti-skidding when touching felts/rugs, flannelette, and loop cloth (terrycloth). Further, the synthetic yarns are tightly woven together so that the synthetic yams do not drive the yams/velvets that make the felts/rugs, flannelette, and loop cloth (terrycloth) out and thus damage the yarns/velvets when being separated. The present invention has excellent touch-fastening characteristics and better resistance against skidding.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
