STRUCTURE OF TOUCH-FASTENING ANTI-SKIDDING MATERIAL
A touch-fastening anti-skidding material includes a knitted foundation layer and a plurality of synthetic yarns that is secured together by being collectively knitted in the foundation layer. The foundation layer is formed by knitting of pliable base yarns and synthetic yarns. The synthetic yarns are knitted in U-shaped loops and the base yarns are knitted between adjacent strands of the knitted synthetic yarns to make a large area cloth. The cloth may be in a planar form without hollow opening sections or it includes open sections to facilitate air permeability. The loops of the synthetic yarns have legs extending beyond the foundation layer by a predetermined length and the synthetic yarns show rigidity strength, whereby a flexible, resilient, light-weighted, and low-cost touch-fastening anti-skidding material is formed.

TECHNICAL FIELD OF THE INVENTIONThe present invention generally relates to a novel design of structure of 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.
DESCRIPTION OF THE PRIOR ARTThe 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 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 knitting 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 fibers/yarns used can be set according to the processing needed. The yarns are knitted to form a foundation layer that can be a net cloth having hollow opening sections (see
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).
SUMMARY OF THE INVENTIONThe primary objective of the present invention is to provide a structure of touch-fastening material, which provides an anti-skidding formed by knitting, whereby the anti-skidding material is flexible and resilient, and which is formed by knitting two types of fibers/yarns of different materials and synthetic fibers/yarns together so that a knitted 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 knitted foundation layer and a plurality of synthetic fibers/yarns that is collectively knitted in the foundation layer and secured together. The knitted foundation layer is formed by collectively knitting two strands of pliable base yarns and synthetic yarns and allowing the synthetic yarns to extend beyond the knitted 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. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.

Further, for adjacent loops, which may be referred to as a rear loop and a front loop, the rear loop 21 is arranged to loop around the front loop 21 and this looping arrangement is repeated 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

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 knitted 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 knitted together so that the synthetic yarns do not drive the yarns/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.
