Textile goods with a knitted chain

The invention relates to a textile product with in loops laid chain for corsetry with a satin-like surface effect, as well as a method of production such a product by interweaving an elastic yarn such that at least two strands under the Outer leg of a non-elastic base yarn of two pass through adjacent wefts, this weaving after every third consecutive row of stitches, of the basic yarn is repeated *

Corsetry requires a fabric with many special characteristics, especially durability, Strength, elasticity and attractive appearance * In conjunction with the latter, which actually the sine qua non in terms of saleability represents the grip of the fabric ο This relates to the feel of the grip the fabric surface that is on the outside the corsetry lies. The ideal is a satin-like grip, which is pleasant in the air and allows the outerwear to move freely »

The prior art knows a large number of arrangements of intertwined warp threads in textile goods, which serve a wide variety of purposes, such as strength, elasticity, stability, etc. 199 449, 3 071 95V 3 183 685, 2 996 906, 2,356 819, 3 011 325, 2 263 and British patent specification 985 666. However , none of these patents describes a fabric for corsetry with a satin-like surface effect of the type described or contains a

XIIe explained at the outset, it is the underlying task of the invention to produce a textile product with intertwined warp threads for low-ware goods, which has a satin-like side or surface of the type described.

A further object of the invention is to produce a new type of textile product and to use a new type of strap formation technology _{or the like}

The invention is illustrated in the following with reference to the drawings explained in more detail using an exemplary embodiment

The fabric according to the invention is made on a warp knitting machine. In the present = ■. The description herein assumes that a Raschel warp knitting machine of any type such as that sold by the Mayer Company _{ZoB 0 is used}

In this embodiment, the front yarn guide tree carries the non-elastic yarn 20, which is used to form the basic or basic network of the goods · B, 40-50 denier. The rear yarn guide tree carries the elastic yarn 30, which is preferably spandex. The latter can be Z ₀ B. HO - 280 denier »

As shown in the drawings, the nylon thread 20 is pulled into hooks while the spandex thread 30 is only inserted into the goods. The payment C 1 to C 10 on the left * edge of the figures in the drawings denote the courses of stitches., while the loading

The same effect can be achieved by using the same pattern for the back tree as listed above, but by changing the direction of the stitching movement by the Needles during stitches 1, 2, 3, 6, 7 »8 can be reached at the front tree as follows «

The goods produced according to the process according to Table A are in the. Drawings. This is shown in a hurry, especially in Figo 2, which shows a repetition of the goods between the rows C 1 and C 10 and the hashes Yi-"1 Ms-IV 6 ₀ The satin-like effect is due to the special way in which the Spandex 30 is inserted into the fabric while the bow-shaped pattern of the G-anies 20. It can be seen that each of the legs 21 of the non-linear yarn, which lie between the rows C 3 and C 4, has two spandex yarns 3tj 32 extends as shown in Fig. 2. It should be noted that Pigo 2 represents only a portion of the Y / are and, if the total values were shown, the other transverse non-elastic yarn sections which are between rows C 3 and C 4 are also underlaid by spandex threads, such as threads 31 and 32, which are under the special yarn thread 21, which is shown running between the IJashen-pure Y / 3 and Y7 4. Of course, the passage of the spandex threads u nter the transversely running non-elastic yarn, s «, B ₀ the threads 31 and 32, which are connected under the legs 21 in FIG.

run to the fact that the legs 21 from the matrix the goods are lifted off while at the same time exerting a pull acting in the opposite direction on each of the legs 21

Similarly, the thread leg 22 (Pig _a 2), which forms the closest stitch in the stitch W 4 of the row C 2, is underlaid by the yarns 31 and 32. These latter have the same effect on the leg 22 as on the leg 21, doho the legs 22 v / ground raised and stretched The spandex yarns 31 and 32 go laterally in a Riohtung under the legs 21 and then run laterally in the opposite direction under the legs 22 o

The spandex yarns 31> 32 pull the adjacent rows of stitches of the inelastic yarns 20 together so that the raised tensioned legs 21, 22 are brought substantially into contact with each other when the tissue is in a relieved state ο

The same positional relationship, as described above, is repeated after a predetermined number of rows, preferably after every three borrowings, as shown in the drawings. So there are the non-elastic thread legs, which run between the rows C 8 and C 9, Z ₀ B, the legs

layer thread or combinations of these can be solved.

The repetitive structure of the y / are like the one above is described, has the strength and durability required for corsetry and as a result of itself

repetitively raised, stretched and brought together inelastic surface yarns 21, 22 and 21a and 22a, the goods are given a satin-like handle. «This smooth satin-like handle is, however, like explained above, 'extremely desirable'

In addition to the grip and appearance benefits described above, the V / are also very easy to manufacture according to the invention <> Dar-

Moreover, in contrast to known processes which knit elastic yarns in, the product according to the invention has no tendency to curl or pucker stay flat _o

Another practical advantage of the invention is that the spandex is spared in that ' Loops in the formed stitches, as with known goods, are avoided «''

The purpose of the above-mentioned known method of loop formation was to fix the spander filaments in tissue to prevent these filaments from slipping in the pusher; au prevent ο In the structure according to the invention, the spandex yarns are also fixed in the fabric and slipping is avoided, but without the liotwendiglreit use additional Spandesf.ad.en for the periodic formation of spandex knitting stitches o The inserted spandex thread is repeated in the structure according to the invention in at least three consecutive stitches of a row of flaps and then in two stitches of the row of flaps next to it.
