Rather, the following description is intended to provide a convenient example for implementing an exemplary embodiment of the invention. Various modifications to the embodiments described below may be made in the function and arrangement of the described components without departing from the scope of the invention as set forth in the appended claims.

Referring to FIGS. 1 and 2, each of the fabrics 10, 10a includes one base layer 40 and has a plurality of hooks 22 protruding from the plane of the base layer 40. . In use, the fabrics 10, 10a are in contact with other fabrics or surfaces (not shown), which can be used to form looped or intertwined structures, such as felt, rugs, flannelettes and looped fabrics (terry fabrics). And the hooks 22 engage and intertwine with the other fabric or surface and pick it up, thereby pulling each other together to form a detachable contact fixture.

The difference between the fabric shown in FIG. 1 and the fabric shown in FIG. 2 is that the edited base layer of the fabric shown in FIG. 1 has a network of holes “X”, which is formed during the knitting process, but FIG. The fabric of 2 is not so.

For simplicity of explanation, in the following description relating to FIGS. 3 to 10, only some of the valleys and columns are shown extending along the length of the fabrics 10, 10a. Such valleys are marked with the symbols "A" and "B". It should be noted that the pattern of stitches shown in the reference figures is repeated along the width and length of the fabrics 10, 10a to allow fabrics of various widths and expandability to be produced.

Both fabrics of FIGS. 1 and 2 are made of warp knit on a warp knitting device of one double needle bed, in which two base layers 40 are simultaneously knitted as one structure (each One layer 40 in the needle bed), stitches 20a, 20b knitted across the two needle beds. Once the knitted structure is removed from the needle beds of the knitting device, the stitches 20a, 20b extending between the base layers 40 are cut to separate the base layers 40, and two The same fabric 10 or fabrics 10a are formed as shown in Figs. 1 or 2, respectively, while the legs 22 of the cut stitch are used to form hooks of the fabric. By varying the tension of the stitches 20, 20b across the needle beds, it is possible to form longer or shorter legs 22.

In order to form the double knit structure which is cut to form the two fabrics 10 or 10a of the present invention, two types of textile yarns or filaments of continuous length are knitted simultaneously. The two types of filaments and yarns used are used for the fibers 20a, 20b to form legs 22 to form the "hooks" of the fabric 10, the flexible yarns 30a, 30b respectively being fabrics. Base layers 40 of 10 are formed and legs 22 are fixed in place within base layer 40.

The fibers 20a, 20b are preferably monofilaments (often also called "Drawn Textile Yarns (DTY)" or injection filaments), and the following artificial plastic materials, i.e. polyamide (e.g. nylon) , Du-Pont Corporation), polyester, polypropylene and polyethylene. Preferably, the monofilaments have a diameter in the range of 0.02 mm to 0.5 mm and have a Shore hardness of 35 A to 90 A or 40 D to 90 D.

The flexible yarns 30a, 30b are preferably made of natural or artificial spun yarns, such as acrylic, cotton yarn, cellulose or polyester cotton yarn blend yarns, and are much more flexible than the fibers 20a, 20b.

3 and 4, two adjacent valleys A and B of the base layer 40 of the fabric shown in FIG. 2 are shown. The alternately formed valleys A are initiated by simultaneously knitting a pair of continuous fibers 20a and 20b and yarns 30a, and each of the valleys A1, in each of the two base layers 40. A2, A3, etc.). At the same time, alternately formed valleys B1, B2, B3, etc. in each base layer are initiated by knitting together a pair of continuous fibers 20a, 20b and yarns 30b.

As described above, when the two base layers 40 are separated, the stitches 20a or stitches 20b extending between the two base layers 40 are cut to form a filament 20a of discontinuous length or Leaving the filaments 20b, each of which comprises a ring 21 coupled to the previous stitch and two legs 22 protruding from the base layer 40, which are shown in FIGS. 9 and 10. The hooks of the fabric 10 or the fabric 10a are formed in a different structure from the one shown.

For clarity, FIG. 3 shows only fibers 20a and 20b and yarn 30a and FIG. 4 only shows fibers 20a and 20b and yarn 30b. In practice, the valleys A1, A2, A3 and B1, B3 of the fabric 10a shown in FIG. 2 are knitted together, with the flexible yarns 30a, 30b crossing between adjacent valleys A, B. Passing through and knitting them with the stitches of the fibers 20a, 20b, as described below.

In Fig. 3, the rings 21 of stitches (second, fourth, sixth, etc.) alternately formed along the valleys of each base layer 40 are of continuous length yarn 30a and fibers 20b. ), But loops 21 of stitches (third, fifth, seventh, etc.) alternately formed along the valleys B of the base layers 40 are fibers 20a of continuous length. ) And the yarns 30a.

In FIG. 4, the rings 21 of stitches (2nd, 4th, 6th, etc.) alternately formed along the valleys B of the base layers 40 are formed of the yarn 30b and the fiber 20a. Loops 21 of stitches (third, fifth, seventh, etc.) alternately formed along the valleys B of the foundation layers, using fibers 20a and yarns 30a Is formed. A cross section cut along each bone length is schematically illustrated in FIG. 5.

The stitch pattern shown in FIGS. 3 and 4 uses a plurality of yarns 30a, 30b and a plurality of filaments 20a, 20b for all the valleys of the base layers 40, and the base layer 40. Repeated transversely on the needles of the two needle beds along the length of the), and thus the stitches 20a, 20b are cut, so as to show any desired two fabrics 10, as shown in FIG. It is possible to knit.

6-8 illustrate a method of knitting the fabric of FIG. 1, in which a hole or gap “X” is formed in the base layer 40 of the fabric 10. The hole "X" may be of any desired geometry, for example round, honeycomb, hexagonal or square or other geometry. The presence of the hole X improves the longitudinal and transverse expandability and deformability of the fabric 10 compared to the fabric 10a shown in FIG.

With reference to FIG. 6, the knitting process seals the first pair of sets of bones A1, B1, A2, B2, and A3, B3 spaced across the width of each base layer 40. It is disclosed by knitting along the stitch patterns as shown in Figs. 3-5, using 30a, 30b) and fibers 20a, 20b.

Initially the alternating pairs of bone sets of the first pair are not joined to the next adjacent pair of bones in the base layer 40. Instead, as shown at the bottom of FIGS. 7 and 6, each of the combined pairs of bone sets of the first pair may have stitch patterns as shown in FIGS. 3 and 4 for a short distance in each of the base layers. Are knitted using.

After knitting a short distance along the pair of valleys, each pair of sets of the first pair of bones A1, B1, A2, B2 and (A3, B3) are in the base layer 40. , Divided into two separate bones, knitted with any one of the adjacent pairs of bones (shown in the top of FIG. 6 and in FIG. 8), and the second pair of bones (B1, A2) and (B2, A3) And so on). The paired valleys (B1, A2) and (B2, A3, etc.) are knitted within each base layer 40 at regular intervals along the length of the base layer 10, which is a yarn 30a. 30b) into adjacent valleys and knit together with stitches of thread 20a, 20b over a short distance along the length of the foundation layer 40.

Subsequently, the paired bones in the second pair of bone sets are each divided into two bones, and the divided bones A1, B1, A2, B2 and A3, B3 are shown in FIG. Knitting each other as shown in the lower portion reassembles the first set of bones. The pattern of stitches is repeated along the length and width of the base layers 40 to produce a fabric 10 of the desired size, thus forming holes “X” in the two layers 40.

As described above, the knitted structure is removed from the needle beds of the knitting device, and the two foundation layers 40 are separated by cutting the stitches of the filament 20a or filaments 20b extending therebetween. To leave two fabrics, which include the discontinuous length of the filament 20a or the filaments 20b, the loop 21 coupled to the previous stitch, and the two legs 22 knitted into the base layer 40. ), And the two legs of each stitch are used to make a hook of the fabric 10 or the fabrics 10a to protrude from the base layer 40.

As the knitting process, the flexible base yarns 30a, 30b are allowed to extend laterally toward adjacent valleys of the base layers 40, and simultaneously knit alternately with the stitches 20a, 20b to form the base layer 40. However, the loops 21 of the artificial threads 20a and 20b are joined to each other along the length of the valleys of the base layers 40 so that the loops 21 of each previous stitch are the next stitch ring ( It will be appreciated that a ring is formed around the peripherys 21, and the tip ends to form short legs 22 of a predetermined length protruding from the base layer 40.

With reference to FIGS. 9 and 10, further features of the present invention are shown, where the filaments 20a, 20b are cut, forming two separate fabrics 10 or fabrics 10a, wherein The fabric 10 or fabrics 10a heat and melt the free ends of the legs 22 of each artificial thread 20a, 20b by passing the fabrics through a tunnel type oven (not shown) to " hook " It is further processed to form rounded ends 23 forming the teeth (see FIG. 9). Alternatively, the free ends of the legs 22 of the respective man-made threads 20a, 20b are pressed to deform the ends upon being heated to form hooks 24, as shown in FIG.

In connection with the fabrics 10, 10a of FIGS. 1 and 2, the short length legs 22 of artificial filaments extend beyond the surface of the base layer 40, protrude out of the base layer 40, and The distance or length of the legs 22 of the artificial thread 20a, 20b can be adjusted as desired, which during the knitting step knits the loops of the fibers 20a, 20b extending across the needle beds. By adjusting the tension to be made into a looser or tighter knit fabric. Shore hardness of the filaments 20a and 20b determines the firmness and rigidity of the legs 22.
