RU2403329C1 - Knocking-over single knitted fabric of plating structure - Google Patents

Abstract

FIELD: textile, paper.

SUBSTANCE: knocking-over single knitted fabric of plating structure has openings formed with plating elastomeric thread that holds cores of thrown off purls, angled to the face of fabric. At that the thrown off knit stitches are loose. The upper edge of the hole consists of sketches, broaches and unclosed stitches of plating structure.

EFFECT: invention expands the range of knitted fabrics used in manufacture of hosiery, underwear and sports products.

Description

The invention relates to the technology of knitwear production.

A single culinary knitwear of uneven (eye) weaves is known, in which the discarded elastic loops open and enlarged smooth loops are formed in the form of holes (1).

The disadvantages of this interweaving is the loosening of the loops of the surface and in this regard, the insufficient degree of dimensional stability of delicate effects in the canvas, as a result of the hauling of threads from the dropped loops.

The technical result of the invention is to obtain a single culinary knitwear with discarded loops that form non-spreading holes without hauling threads, which makes it possible to expand the scope of this type of knitwear.

The technical result is achieved by the fact that only the discarded facial loops dissolve and the inclined cores of the discarded purl loops hang on the straightened portion of the elastomeric thread of the thread.

Thus, the dropped plated loops form a kind of lock, which provides tightening of the loops of the lower edge, the hole formed without the waist, and the upper edge of the hole is formed by sketches, broaches and open loops of the looped rows of earning cloths of the plaited weave. The number of loops dropped and earned determines the size and shape of the holes in the knitwear.

Figure 1 presents a graphical record of the interweaving of a plated surface with discarded and open loops, as well as drafts and broaches; figure 2 is a diagram of the loop structure of a single culinary knitwear with a plated weave with the loops, holes and straightened elastomeric thread; figure 3 is a diagram of the formation of holes with non-blooming lower and upper edges.

The proposed structure of the knitwear with knitted loops is formed in the process of knitting on a single-loop multi-system machine with individual selection of working bodies and elastomeric yarn feeders, the use of which allows you to produce a fabric with non-expanding holes and make needles after dropping the paid loops from them.

The weave of the plated smooth surface, Fig. 1, with group discharges of loops P _sat in the II and VI loop rows and, respectively, in 2-5 loop columns, purl loops P _{and are} formed from soil thread H ₁ , and the front loops P _l from the plating thread H ₂ . In the III-IV and VII-VIII loop rows, discontinuous loop bars 2-5 contain the outline H _b , broaches P _r and open loops P _n , and the full loop columns 1 and 6 define the boundaries of the group discharge of loops.

Figure 2 illustrates the diagram of the loop structure of a single culinary knitwear with the loops dropped, which form the holes after a group discharge in the II and VI loop rows, loops П _{п of the} plated smooth surface from soil filaments H ₁ and plating elastomeric Н ₂ , elastic force P of the stretched elastomeric thread Н ₂ dissolving facial loops and form straightened thread portion which tightens purl loops _and n and prevents constriction yarns in III-IV and VII-VIII hinge discontinuous rows looped columns 2-5 contain outline H _b, broaches _EXAMPLE n closed loop P _n.

The hole forming is carried out in a four-cycle knitting process, shown in figure 3.

In the first knitting cycle, plated smooth loops P _{n are formed} , the front loops of which are formed from an elastomeric thread, and the wrong ones from a less elastic ground thread.

In the second knitting cycle in the dumping system, the platen loops are dropped from the selected needles, the elastic forces P of the stretched elastomeric thread H ₂ open the front loops, form a straightened section of the OO thread, the skeins of the purl loops P _and, under the influence of the internal weaving forces F, the surface is bowed to the front side and form a kind of lock, hang on the O-O thread in the form of a non-blooming fringe, this state of the loop structure is considered as the “clothesline” effect.

In the third cycle of knitting needles without loops are included in the work for the formation of the upper edge of the hole from the outline H _b and broaches P _r when laying the ground and plating threads, respectively, on the needles and needles.

In the fourth knitting cycle, the needles are fully earned, on which loops of the paid surface are formed.

As a result of four knitting cycles, the lower and upper edges of the non-expanding hole are formed, which is bounded on two other sides by continuous loop columns 1, 6 of the proposed structure of the knitted single knitwear with the loops dropped.

Claims (1)

A single crocheted plain knitwear in which the discarded front loops are dissolved and the skeletons of the discarded back loops are inclined to the front side of the fabric and hang on the elastomeric thread of the fabric, together with which the loops of the lower edge of the formed hole are prevented from dissolving, while the upper edge of the hole consists of drafts , broaches and open loops of a paid weave.
