Description

Title: Structure of touch-fastening anti-skidding material (a) Technical Field of the Invention

The present invention generally relates to a novel designof structure of touch-fastening anti-skidding material, whichhas the features of being fit for mass production andmanufacture of large width surface area, flexibility,resiliency, and light weight, and also offers the advantagesof high air permeability and low manufacturing costs, and isfit for combination with other materials and suitable forbeing 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 bandhas a surface forming a felt-like face on which a plurality ofprojecting hooks that has ends forming hooks is uniformlydistributed. The female loop band has a surface forming avelvet-like face on which curled and entangling yarns areuniformly distributed. When the male and female bands are puttogether to have the felt-like face and the velvet-like facesthereof touching each other, the hooks of the felt-like facelargely engage the curled and entangling yarns so as to fixthe bands together. The known structure of the touch-fastenerstrap is effective in fixing articles to be fastened together,but the conventional touch-fastener strap suffers highmanufacturing costs and difficulty in making large widthproducts, and is only fit for 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 difficultto bond to articles or materials showing a three-dimensionalconfiguration. To overcqme such problems, the presentinvention aims to provide a unique touch-fastening material,which can be manufactured by weaving synthetic fibers/yarns ofdifferent characteristics or synthetic fibers/yarns ofdifferent diameter sizes in order to suit the needs ofdifferent applications, wherein the length of the · syntheticfibers/yarns used can be set according to the processingneeded. The yarns are woven to form a foundation layer thatcan be a net cloth having. hollow opening sections (see FIG. 1of the attached drawings) or a net cloth having no hollowopening sections (see FIG. 7). When the net cloth so wovenhaving hollow opening sections, the hollow opening sectionscan assume various shapes, such as circle, honeycomb,quadrangle, and other geometric shapes. The formation of thehollow opening sections provides the anti-skidding materialwith enhanced resiliency for stretchability and deformation inboth length and width and improved air permeability. Thisalso offers an advantageous feature of enhanced shapeabilityfor forming a three-dimensional configuration for surface¬bonding to other materials that may show three-dimensionalconfigurations. Since the synthetic fibers/yarns are woven inthe foundation layer, all the synthetic yarns are tightlysecured together without undesired separation off and thusadditional adhesive layer applied to the bottom thereof forbonding purposes is not necessary. This makes the material ofthe present invention advantageous in view of manufacturingcosts. The touch-fastening material of the present inventionmay·also be subjected to additional processing by passingthrough a tunnel-shape oven, in which ends of the fibers/yarnsare melt and form hooks with rounded end. The touch-fasteningmaterial of the present invention provides excellent resistance against skidding and thus offers extremely wideapplications for anti-skidding material in various industries.Thus, the present invention aims to provide a mass-productive,light-weighted, air-permeable, resiliently expandable, andstructure simplified anti-skidding material that provideseffective skidding resistance for various material, includingfelts/rugs, flannelette, and loop cloth (terrycloth).

As shown,the touch-fastening anti-skidding material in accordance withthe present invention, generally designated at 10, comprises aplurality of synthetic yarns 20a, 20b and pliable base yarns30a, 30b.

Also referring to FIGS. 3-5, each synthetic yarn 20a, 20bis 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 thatthe loops 21 are linked together with the short legs 22 thatare located at ends of the loops 21 and of a predeterminedlength extending outside a foundation layer 40. The syntheticyarns 20a, 20b are accompanied by the pliable base yarns 30a,30b in an alternate manner in the front-rear direction (seeFIGS. 3 and 4) so that the first synthetic yarns 20a iscombined with the base yarn 30a, while the second syntheticyarn 20a that is linked to the first synthetic yarn 20a iscombined with the base yarn 30b. Similarly, the firstsynthetic yarn 20b is combined with the base yarn 30b, whilethe second synthetic yarn 20b that is linked to the firstsynthetic yarn 20b is combined with the base yarn 30a. Inthis way, two strands are collectively woven in a dual yarnmanner to form a woven strand A (as shown in FIG. 1A). Thesynthetic yarns 20a, 20b and the base yarns 30a, 30b arecollectively woven on a common horizontal plane and form afoundation layer 40. The base yarns 30a, 30b that arearranged to parallel accompany the synthetic yarns 20a, 20bare arranged in such a way that the base yarns 30a, 30b, afterco-bent with the synthetic yarn to form the loops 21, are allowed to individually and transversely extend to andsubsequently parallel accompany the synthetic yarn 20a·, 20b ofan adjacent strand (see FIGS. 3 and 4). The synthetic yarns20a, 20b can be made of nylon plastics, or polyesters, orpolypropylene (PP) plastics, or polyethylene (PE) plastics.

As shown in FIGS. 3-6, the base yarn 30a, which isarranged to co-extend with the synthetic yarn 20a form a loop,is allowed to extend transversely to the synthetic yarn 20b ofthe adjacent stranjd for subsequently co-extending with thesynthetic yarn 20b for dual yarn weaving, so that thesynthetic yarns 20a, 20b and the base yarns 30a, 30b are wovenin a common horizontal plane to form the foundation layer 40.The foundation layer fabric comprises loops 21 of thesynthetic yarns 20a, 20b linked to each other in the front-rear direction, so that the rear one of the loops is set toloop around the front one of the loops and each of the linkedloops 21 has ends that form short legs 22 of predeterminedlength extending outside the foundation layer 40. When thetransversely extending base yarns are of great lengths, thelengths of the base yarns allows for formation of gaps X thatdefine hollow openings, whereby the foundation layer 40 isprovided with hollow opening sections, which can be of. anydesired shape, such as circle, honeycomb, quadrangle, andother geometric shapes. The presence of the hollow openingsections helps improving stretchability and deformability inthe longitudinal direction and the transversely direction.

As shown in FIG. 7, the present invention provides atouch-fastening anti-skidding material 10a, which comprises alarge area cloth formed by weaving of the foundation layer 40in an expanded manner, wherein the base yarns 30a, 30b thatare woven in the foundation layer to extend transversely inthe planar surface of the cloth are arranged in a tightenedmanner so that no gaps X that form hollow openings are formedby 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 ofthe present invention is provided, wherein the touch-fasteningmaterial of the present invention, after being formed bycollectively weaving the synthetic yarns 20a, 20b and the baseyarns 30a, 30b, is further processed by passing through atunnel-type oven for heating, whereby free ends of the legs 22of each synthetic yarn 20a, 20b are fused to form rounded ends23 (see FIG. 8). Alternatively, the free ends of the legs ofeach synthetic yarn 20a, 20b is subjected to heating andcompressed to form hooks 24 (see FIG. 9). The short legs 22of synthetic yarns extending beyond the surface of cloth soformed by weaving are set to project outside the foundationlayer and the distance or length of the legs 22 of thesynthetic yarns 20a, 20b can be adjusted as desired, and thesynthetic yarns shows rigidity strength.

Thus, the touch-fastening anti-skidding material inaccordance with the present invention possesses advantages oflight weight, high air permeability, and flexibility and isfit for mass production of large width products.

To summarize, the present invention provides, a touch¬fastening anti-skidding material that is structured by havingsynthetic yarns of short lengths woven together with the cloththat forms a foundation layer to provide the effect of anti¬skidding when touching felts/rugs, flannelette, and loop cloth(terrycloth).
