Description

The invention dilutes the widening of the weave structures of knitted woven fabrics, which offer the possibility of creating new exemplary structural designs and at the same time creating fabrics in which the face and back sides differ substantially in appearance and properties.

It is known fabric semi-woven and semi-knit, which is made on a rasp with a simple needle bed from French pat. No. 2,176,179 · The fabric has alternately chain groups and warp yarn groups, wherein the pillar strands bounding from each side of the warp yarn group are interconnected by weft yarns running from one side to the other side of the warp group and in one case they lie on and under the warp threads and in the second case the weft threads are interwoven with the warp threads in a weaving weave · The warp threads are located between a knitting weave formed by pillars of chains *

A weave formed from warp yarns and stitch connecting loops is also included in the fabric of the USSR description of the invention to Patent No. 427,519. The warp yarns lie between two adjacent stitches, alternately stitching the stitches of each post with the stitches in adjacent right and left post . The loops of stitches run alternately below and above the warp threads.

- 2 NSR OS No. 3 016 270 contain · knitted fabric, which consists of warp yarn areas and double weft yarns forming woven weaves, between which the stitch pillars are located, where the double weft yarns always run over one or more areas; that the fabric comprises knitted areas formed from a plurality of adjacent stitch pillars adjacent to the woven regions, and the stitches may be interconnected or interconnected with each other · The machine for manufacturing the fabric is arranged such that the needles and their associated needles are in those places a needle bed or a laying device, on which the stitch columns are to be formed.

The knitted fabric is constructed to contain a knitting warp in the form of stitch columns whose pairs of tie loops tie together with groups of warp yarns in a weave and form flow woven strips located between the stitch pillars of knitting weave · Pairs of tie loops run parallel to most · In the case of the bond shown in the description of the invention to the USSR patent No. 427 519, the pairs of connecting loops are not parallel to one another.

The invention is directed to expanding the range of these knitted fabrics by providing at least one retractable loop or retracting loop on one arm of the pair of looping loops. These retracting loops or loops are located in the woven fabric web between the return warp knitting loops. pair of connecting loops parallel to each other · One thread of the pair of connecting loops runs under the formed loops or stitches of the other thread belonging to the pair of connecting loops of the stitches of the knitting warp binding ·

The eyelets formed on the same arms of the pair of connecting loops interconnect in columns · «3 230 768

According to another variant of the embodiment of the knitted fabric, the stitching loops interweave the knitting warp links in the columns with the return warp loops. Such two adjacent stitch columns have mutually offset stitching eyes and restoring warp stitches, with stitching stitches alternating with stitching stitches in each stitch post.

The 'aox' design of the knitted fabric creates free-flowing loose plush pillars. There are warp threads between the columns of pulling loops or between the columns of pulling loops, which bind by some loom with pairs of connecting loops ·

The creation of one or more stitching loops on one of the pair of stitches forming the split weft is possible for all previously known knitting weaves in knitted fabrics, for example according to АО No. 162 119 or 162 120. Newly formed stitching loops can tie in the fabric in three basic ways with each other to form a pile of retractable loops or alternately with restoring warp loops, to form a pillar combined of retractable and warp return loops, or non-tie loops, and to form a stack of loose plush loops in a knitted fabric.

This method of forming a pulling eyelet, possibly plush loops, is theoretically possible in all known methods of interconnecting the loops of warp knitting ties with a group of warp yarns. It brings the possibility of structurally new fabrics with a predominantly knitted character. the nature of the fabric on the other side of the fabric, whereby the finished fabric on the face side of the fabric and on the reverse side of the knitted fabric properties is achieved, and vice versa

Another possibility resulting from the proposed method of interweaving yarns is the possibility of producing knitted woven fabric with a loop and / or dia. hair surface made of weft material ·

At the same time, the structural difference between the fabric and the woven fabric is accompanied by the fact that on the one hand the weft fabric and the warp material predominate, which can be advantageously used for the construction of physiologically suitable fabrics or technical fabrics with different properties. the opposite sides of the fabric, given the warp and weft material used.

All these described uses of pull lugs offer the possibility of a substantial extension of the assortment and usability of knitted woven fabrics, as they significantly affect the properties and appearance of these fabrics.

The knitted fabrics according to the invention are specified in more detail in the drawings, in which Figs. 1, 5 and 6 indicate the bonding of the columns formed from the pulling eyelets, Figs. 9A, 10A, 11A and 12A exemplary weave variants of fabrics, FIGS. 9B, 10B, 11B and 12B schematically show the method of laying weft yarns corresponding to the respective weave structures of the fabrics of FIGS. 9A, 10A, 11A and 12A, Figs. 13A, 13В, 13C, 130, 131 cross-sections of a woven strip of knitted fabric with an added pulling eyelet or loop formed from one arm of the stitch tie loops and Figs. 14A, 14В; 14C, 140, 14E modification of the machine or needle bed for the production of the knitted fabric according to the invention ·

Figs. 9A, 10A, 11A, 12A show some examples of newly formed weave structures in which the known laying of weft threads 15, namely carp, catch carp, leotard and skirt, is used in combination and in various ways of interlocking the pull loops. Fig. 9B, 1OB, 11B and 12B show schematically a method of laying a weft yarn 15 corresponding to the respective weave structures.

Giant. 9A shows the weave structure using the basic leotard lay 16 of the weft yarn 15 (FIG. 9B). The pulling loops 1b do not interact with each other, on the side of the eyelets there are plush columns 2 of loosely lying loops 1b. the spacing of which corresponds to the position of the auxiliary needles 10 not shown so that the shoulder of the working needles 11 is offset against the needles 12 and is filled with the auxiliary needles 10 (cf. FIGS. 14A to 14E). The plush posts 2 correspond to the arrangement according to FIG.

The warp threads 8 lie to the left and right of the plush column 2 with loops 1b and interweave in a weave with pairs of connecting loops 2 of the return warp stitches 6 of the knitting linkage. The weft yarns 15 form the connecting loops 2resp. weft loops 6 which are parallel to each other in the width of the woven strips.

In an alternative embodiment, the plush posts 2 of Figure 9A may be replaced by the arrangement of Figure 4 or Figure 7.

Giant. 10A shows a weave structure using a basic twill lay with a grip 12. The retraction loops 1 interconnect and form columns 2 that correspond to the exemplary layout of the auxiliary needles 10 of FIG. 14E. The stitches 1a in section 13a lie side-by-side (according to Fig. 5), the position of the stitches 13a (Fig. 14B) corresponds to their position.

Giant. 1OB shows twill laying β by grip 17 of weft yarn 12 *

Giant. 11A represents the weave structure using the basic dill laying 18 of the weft yarn 15 threaded in even laying needles 12. On the auxiliary needles 10, the stitching eyes 1a are formed from these yarns. Odd laying needles 12 have half the length of laying. The stitching of these stitches results in a stitching column alternating between the pulling la and the restoring warp stitches 6 of FIG. 2. The position of this stitching post 2 corresponds to the positioning of the auxiliary needles 10 of FIG. 14A using different laying lengths.

Fig. 11B shows the weft yarn 15 in the dill laying 18 as shown in the previous Fig. 11A.

Fig. 12A shows the weave structure using the weft threading 19 of the weft yarn 15.

Fig. 12B illustrates the weft yarn laying 19 of the weft yarn 15;

13A to 13B are cross-sectional views of a woven strip of knitted fabric with an additional stitch loop 1a, respectively. 13A, 13В, 13C, 130, 13E, it can be seen that the weaving process affects the shape, inclination and fixation of the eyelet 1a (Figs. 13A and 13B) respectively. plush loops 1b (Figs. 130, 130, 13E) in a knitted fabric.

The modification of the machinery for the production of the above-described fabric consists in the retrofitting of the needle bed 2 of the basic knitting machine according to the art. No. 153,246, further auxiliary needles 10 disposed between the working needles 11 of the machine. One or more of these auxiliary

Depending on the fabric structure being formed, the needles can be positioned arbitrarily within the section 13 between the two working needles 11. Because of this arbitrary arrangement of the auxiliary needles 10, which is not dependent on existing working bodies, the range of newly formed weave structures is very wide. Examples of needle locations are shown in FIGS. 14A, 14B, 14C, 14D, 14E. Giant. 14A shows one or more auxiliary needles 10 in the middle of section 13. FIG. 14B two or more auxiliary needles 10 symmetrically in section 13. FIG. 140 one auxiliary needle 10 unsymmetrically in section 12 »FIG. As shown in Figure 13B, the pattern of the auxiliary needles 10 in the sections 13, including the combination with the empty sections 14, i.e. without the auxiliary needles 10, can be repeated.

When using several auxiliary needles 10 in one section 13, the pulling eyes 1a may lie either side by side (FIG. 5) or they may tie the warp threads 8 in a weave between them (FIG. 6). The plush loops 1b must be secured from both sides by a weave, ie warp threads 8 (Fig. 7).

The number of new weave structures is further expanded considerably using two sets of weft yarns, since the weft yarns of each set can be used to form the pull loops 1b or stitches 1a. Advantageously, variable lengths of laying can also be used, which provides additional possibilities for creating new structures in combination with auxiliary needles 10, for example alternating the pulling eyes a with the return warp eyelets 6 in the same line of fabric (FIG. 8).
