Description

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

The present invention generally relates to a novel design of structure of touch-fastening anti-skidding material, which 5 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 10 being bonded to various felts/rugs, flannelette, loop cloth (terrycloth) to realize touch-fastening and anti-skidding.

(b) Description of the Prior Art 15 The commonly known touch-fastener straps or hook-and-loop (Velcro) straps 'have the features of touch-fastening and antiskidding. 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 20 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 25 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 30 manufacturing costs and difficulty in making large width products, and is only fit for continuous manufacture of small-surface-area elongate straps, making the production 1037664 2 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 overcqme such problems, the present 5 invention aims to provide a unique touch-fastening material, which can be manufactured by weaving synthetic fibers/yarns 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 10 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 15 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 20 both length and width and improved air permeability. This also offers an advantageous feature of enhanced shapeability for forming a three-dimensional configuration for surfacebonding to other materials that may show three-dimensional configurations. Since the synthetic fibers/yarns are woven in 25 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 30 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 3 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 5 structure simplified anti-skidding material that provides effective skidding resistance for various material, including felts/rugs, flannelette, and loop cloth (terrycloth).

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

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. 15 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, 20 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 25 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 in FIG. 1A). The 30 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 35 co-bent with the synthetic yarn to form the loops 21, are 7 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 5 polypropylene (PP) plastics, or polyethylene (PE) plastics.

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 stranjd for subsequently co-extending with the 10 synthetic yarn 20b for dual yarn weaving, so that the synthetic yarns 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-15 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 20 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 25 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 30 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 8 , 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 . 5 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 yarn 20a, 20b are fused to form rounded ends 10 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 15 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 20 light weight, high air permeability, and flexibility and is fit for mass production of large width products.
