Abstract

FIELD: manufacture of knitted product. SUBSTANCE: method involves forming fabric by means of single-loop and double-loop combs, with combs being partially drawn in, combs offsets being oriented in opposite directions and both combs knitting similar weave - woolen cloth and satin-like cloth with open loops; laying threads on needles of one needle box; providing knitting by three-loop and four-loop combs on needles of first and second needle boxes; providing parallel laying by five-loop comb and six-loop comb of thread on needles of one needle box. Five-loop comb effects loop weaving by laying thread on the same needle and six-loop comb provides five-needle "charmeur" weaving, where thread is laid alternatively in one row on first needle and other row on fifth needle. Method allows increased bulk knitted fabric with high physicomechanical properties to be produced. Said fabric may be used as covering material. EFFECT: simplified method, wider range of employment and improved quality of bulk knitted fabric. 5 dwg

Description

 The invention relates to the field of knitwear production, and in particular to a technology for the production of bulk warp knitwear, which can be used as a substitute for triply material.

 A known method of producing a single warp knit, according to which the filament is tucked into the first comb, the pile into the second comb, and the comb is considered to be the first comb located closer to the backs of the needles. First, soil and pile threads are laid on the needles, while the needles are pressed. In the next cycle of movement of the loop-forming organs, only pile threads are laid on the needles and in this cycle the threads are not pressed. Further, the process is repeated in the described sequence [1]. The disadvantage of this method is that the increased volume of the resulting fabric due to the presence of pile, which excludes its use as a substitute for triply materials.

 Closest to the claimed one is a method of obtaining a pile knit on a warp knitting machine [2], which consists in the fact that the threads of two combs are laid on the needles to form loops of soil with fillet weaving so that each needle that receives the thread knits one loop of soil, and for the formation pile broaches use additional threads tucked into other combs with a partial parting, moreover, for the formation of pile broaches without knitting between the looped posts of the comb with additional threads p rock and slide behind the needles one needle step in the direction of the shift of the soil combs. This method is selected for the prototype.

 The disadvantage of this method is that the resulting fabric has an increased volume only due to the pile surface, which excludes its use as a substitute for triply materials.

 The problem to which the invention is directed, is to obtain a knitted fabric of increased volume with high physical and mechanical properties, suitable for use as upholstery material, for example, instead of triple artificial leather.

 The problem is solved in that in the method of obtaining three-dimensional knitwear on a warp knitting machine, including forming a web by fillet weaving, using the I and II ear combs, in which, unlike the prototype, the shifts of the I and II ear combs are directed in opposite directions, and both they knit the same weave - cloth - satin with open loops, and the parting of these combs is partial, lay the threads on the needles of one needle bar, III and IV combs are knitted on the needles of the first and second needle bar, combs V and VI are parallel masonry, laying the thread on the needles of one needle bar, with comb V weaving the chain, laying the thread on the same needle, and comb VI weaving the five-needle charm, where the thread is laid alternately in the same row on the 1st needle, in the other on the 5th.

 Figure 1 shows a record of the work of I and II of the ear combs, figure 2 shows a record of the work of III and IV of the ear combs. Figure 3 shows a record of the work of V and VI combs. Figure 4 shows an analytical record of the patterned chains for the production of three-dimensional knitted loin (a) and three-dimensional smooth knitted (b).

The technological process for the production of three-dimensional knitted fabric in accordance with the claimed method is as follows. For knitting a three-dimensional knitted fabric at the applicant enterprise, the following is used:
- polyamide monofilament 3.3-4.3 tex;
- polyester textured dyed yarn 9.3 tex;
- polyester complex thread 5.0-8.4 tex.

 First, raw materials are prepared by warping synthetic complex textured yarns and monofilaments, which are carried out on sectional warping machines of the model DS N 21-30 by K. Mayer. Knitting of a knitted fabric is carried out on warp knitting double-knit machines of the type RD6 DPL V.12 - 3 22 class of the company K. Mayer of Germany. In the process of knitting I and II, duck combs form a fillet weave. The shifts of the combs are directed in opposite directions. Both combs knit the same combined weave - cloth - satin with open loops. Parting part I and II of combs is partial, lay the threads on the needles of one needle bar. The rapport of the figure is 16 looped rows. Combs III and IV are seasoned with monofilament with a partial parting. Combs III and IV are knitted on the needles of the first and second needle beds, thereby combining two sheets - fillet and smooth. The distance between the needle bars will determine the thickness of the three-dimensional fabric. To improve the processing ability of monofilament, it is recommended to install two additional combs of positions KB-X-2-1 and KN-X-6-7.

 Obtained by the claimed method, the material has good physico-mechanical and aesthetic indicators and approaches triplicated materials, which makes them interchangeable. The raw materials used are also new - monofilament and colored textured thread instead of harsh. This makes it possible to obtain material of various colors with high strength characteristics. The change of chains on the 1st and 2nd combs allows you to get both a smooth and loin surface of the material.
