Description

The invention relates to the field of knitwear production technology, namely to the production of culinary two-elastic knitwear, and can be used in the knitwear industry for the production of household and technical products.

Known two-elastic or interlock culinary knitwear 1 + 1, which is a derivative of the eraser and is a combination of two erasers 1 + 1, nested in such a way that between the looped posts of one eraser are looped posts of the other eraser [1] // Dalidovich A.S. . Fundamentals of the theory of knitting. - M.: Light Industry, 1970, p. 219, Fig. 104 - analogue //. This knitwear is double-faced, i.e. it has only front loops on both sides and has a number of valuable properties: reduced bloatability, lack of curl, high elasticity, good stretchability, almost like an eraser. A significant disadvantage of the two-plastics is the low dimensional stability, expressed in the increase in its width while decreasing the length during operation.

Known purl interlock knit with high dimensional stability, on both sides of which all the loops are purl [2]. Its disadvantage is the technological impracticability of obtaining such a structure on knitting equipment of a modern technical level. // RF patent No. 2156840, MKI D04B 1/00. Wrong interlock knit.

Knitwear is also known from the prior art, which the authors called a two-layer derivative eraser by weaving and containing only front loops with elongated broaches on both sides of the fabric, each row being connected with at least two threads that alternately form loops with an offset of one needle step [ 3]. This technical solution is the closest analogue of the claimed invention. // RF patent No. 2209261, MKI D04B 1/00. Knitwear weave two-layer derivative eraser.

This interlacing is a combination of incomplete erasers sequentially formed with a one-needle offset, can be complete and incomplete in the presence of loop stitches, contains elongated broaches of the erasers connecting the loops of the front and back sides in the structure, and has high dimensional stability. The disadvantage of this well-known weaving is a certain imbalance in the structure, due to the sequential knitting of the erasers with a shift of one needle step and expressed in the fact that in its structure the loops of the incomplete erasers that form it are not located opposite each other, they can have a different number of loops on the front and back sides. The observed unevenness in the structure leads to undesirable unevenness of the physico-mechanical and other operational properties.

Another drawback of this interweaving is the limited amount of displacement of the partial erasers that form it, which sufficiently limits the possibilities of structure formation and the creation of various patterned effects.

The objective of the invention is the creation of a basic weave having a balanced structure and having high shape stability, and expanding the range of two-piece (interlock) knitwear.

The problem is solved due to the fact that the derivative two-elastic knitwear contains at least two two-plastics, nested in such a way that between the loop columns of one two-elastic are looped columns of the other or other two-elastic, and each row is formed by the sequential formation of one, two or more two-plastics of filaments forming loops with an offset of one or more needle steps.

The advantages of the proposed derivative of bilastic (interlock) knitwear are the presence of a form-stable two-face balanced structure in which on each side the loops of one two-elastic are opposite the loops of the other two-elastic and have elongated broaches of the same length, the length of which is determined by the displacement of the loops when knitting the incomplete erasers that form them.

An additional advantage of the inventive knitwear is the possibility of obtaining balanced lightweight structures with reduced material consumption on its basis by forming incomplete structures with missing looped posts in place of one or more two-plastics.

Another advantageous feature of a bilastic jersey derivative is the increased ability to achieve structural and color patterned effects when using materials of different color, composition and properties due to the presence in the structure of the invented jersey of two or more two-laced weaves, each of which is two incomplete erasers, and more threads in one loop - for complete structures, at least four threads.

The inventive derivative bilastic knitwear is produced on modern double-circuit multi-system double-bladed machines having a multi-level selection of needles in the disk and cylinder, i.e. needles with different heel levels and multi-channel locks. Its development does not represent technological complexity and does not require additional devices and operations with loops.

Preferred variants of the structures of the claimed weave are produced by interlocking the needles in the fonts of a two-blade machine. Fundamentally, a proposal for an application does not exclude its development even with an elastic arrangement of needles, it also allows one to obtain knitwear with the claimed distinguishing features, however, the degree of balance in the structure of knitwear will be slightly lower than that developed during interlock arrangement, due to the displacement of the two plastics in a row relative to each other by half needle pitch.

Figure 1 presents a variant of the structure of the claimed derivative of two-knitted knitwear, which is a combination of two two-plastics and which can be called a doubled full derivative two-elastic with a needle-like displacement with the following parameters: rapport across the width Rb = 2 and completeness (number of systems) for generating one row of weaving K, determined by the number of knitted threads and equal to the vertical rapport K = Rh = 4, the amount of displacement is one needle step.

On figa presents a graphical record of one loop series of this structure on the needles 1-8 of one side (cylinder) and on the needles 1'-8 'of the other side (disk) of four threads: H1, H2, H3, and H4, each of which forms a loop of an incomplete eraser with an offset of one needle step relative to the loop of the previous side. So the first thread H1 forms loops on the front side in columns 1.5 and on the wrong side in columns 3 ', 7', connected by elongated broaches. Thread H2 forms loops in the same columns on the opposite side, namely in columns 3, 7 of the front side and 1 ', 5' of the wrong side. Thread 3 forms loops in columns 2, 6 and 4 ', 8', and thread H4 in columns 4, 8 and 2 ', 6', respectively, of the front and wrong sides. The constant displacement of the elastic loops determines the same length of the broach P. Fig. 1b summarizes the graphical representation of the first DL1 and second DL2 two-plastics, formed by the corresponding pair of threads H1, H2 and a pair of threads H3, H4. The loop structure of doubled incomplete two-layer with the loop offset by one needle step, shown in Fig.1c, clearly demonstrates its two-sided double-faced balanced full structure: all the loops from the front and the wrong sides are front and have the same structure, there are no missing loop bars, the number of loops one by one the side is equal to the number of loops on the other side of the weave, the front loops of one dvolastic from the threads H1 and H2 are located opposite the loops of the other dvolastic from the threads H3 and H4, the broaches are the same in tench. Elongated broaches are located inside between the loops, limit the elongation of the knitwear, therefore, increase its shape stability.

The invention is also illustrated in figure 2 by a variant of the structure, which is a combination of three two-plastics with a two-needle displacement of elastic loops with parameters Rb = 2, K = Rh = 6. It can be called a triple full two-needle with a two-needle offset. On figa presents a graphical record of one row of weaving, on figb is an explanatory graphical record of all three dlastikov DL1, DL2 and DL3, formed respectively by a pair of threads H1, H2, then a pair of H3, H4 and finally a pair of threads H5, H6 . Figure 2c depicts the loop structure of this embodiment of the inventive knitwear having broaches greater than the doubled derivative two-length length and, as a consequence, greater dimensional stability.

A further increase in the displacement of the loops of incomplete erasers in the structures of the claimed derivative of two-knitted knitwear to three, four or more will further increase the dimensional stability due to the length of the broaches, however, it is ineffective from the point of view of increasing material consumption and reducing the productivity of knitting equipment.

In any full structure of the proposed knitwear, adjacent loop stitches represent different two-plastics, knitted from different threads, therefore, using for the first and second pairs of threads yarns of different colors, thicknesses, types, or differing in other, for example, elastic and stretchable properties, creates color, relief, tint and others, including compression, effects. This circumstance, as well as the large number of elongated broaches located between the sides of the knitwear, increasing its shape stability and increasing thickness and breathability, makes the claimed weave preferable for use in the production of fabrics for both household and technical knitwear for various purposes.

To obtain lightweight structures as variants of the inventive knitwear, incomplete structures of derivatives of bilastic weaves are preferred, in the structure of which, on the site of one or more bilastics, there are missing looped posts.

Figure 3 presents the derivative of an incomplete bilastic knit with an offset of one needle step, a graphical record (figa) and a loop structure (figb). This incomplete structure at the site of one of the two plastics contains even (2, 4, 6, 8, and 2 ', 4', 6 ', 8') looped columns missing on both sides. The structure is also double-faced, has reduced material consumption and open elongated broaches, which creates an additional delicate effect in the form of longitudinal stripes.

The derivative incomplete bilastic knit depicted in FIG. 4 with a two-needle offset contains loops of only one bilastic produced on the needles 1, 4, 7 of the front, on the needles 1 ', 4', 7 'of the wrong side, and instead of two other nested two-plastics there are missing columns 2, 3, 5, 6 of the front and columns 2 ', 3', 5 ', 6' of the wrong side (figa). The loop structure of this incomplete derivative of a two-needle with a two-needle offset in Fig.4b is also lightweight, leads to significant savings in raw materials and demonstrates the presence of a significant and clearly visible openwork effect.

The proposal on the application does not exclude the possibility of producing press, plated, lined, plush, incomplete and other patterned weaves based on the claimed derivative of two-knitted knitwear.

The considered options for the structures of the inventive knitwear allow us to talk about a significant expansion of the assortment of bilastic (interlock) knitwear when using the inventive weave.
