RU2367732C1 - Method of knitting brushed and weft knitted fabric - Google Patents

Abstract

FIELD: textile, paper.

SUBSTANCE: invention relates to textile production. The method of knitting weft knitted fabric is realised as follows. When ground loops are transferred from needles of one needle bed of seamless loop-forming sinker web machine to needles of another needle bed, a fleece yarn is stretched on the needles and at the same time loops of the fleece yarn is knitted on the needles from which the transfer is carried out, overcast of fleece yarn is stretched on the needles on which transfer to transferred loop of the ground is carried out. Thereafter the ground loops with overcast of fleece yarn are transferred backward to the same needles from which they were taken off. Thereafter, further course of the ground is knitted extending the ground loops through the ground loop of the previous course and overcast of the fleece yarn.

EFFECT: reliability of mechanical process of stretching fleece yarn on the needles of seamless loop-forming sinker web machine with forming double wrap of needle shank from the side of a hook.

Description

The invention relates to the technology of knitwear production.

A known method of knitting a knitwear knitwear, in which during the operation of laying the thread and forming a thread, the thread is laid behind the back of the needle, and then wraps around the needle, forming a loop. [1] The disadvantage of this method is the complex movement of the yarn guide around the needle shaft, which cannot be achieved mechanically on the flat knitting cooler machines of existing structures.

There is a known method of knitting knitwear knitwear, in which the threads are laid on the needles of the front and rear needle beds, forming sketches, then the sketches are transferred from the needles of one needle box to the sketches of the needles of the other needle bed, as a result of which the thread is formed on the needles with double twisting of the needle shaft from the hook side . [2]

The disadvantage of this method is the unreliability of the process of transferring one sketch to another, because the draft force of the web does not act on the drafts, and to keep the drafts at a certain level when the needles are raised during transfer, the action of the bar pull mechanism is not always effective.

The technical result of the invention is to ensure the reliability of the mechanical process of laying the lining thread on the needles of a flat knitting cooler with the formation of a loop with double wrap of the needle shaft from the hook side.

The technical result is achieved by the fact that the lining thread is laid on the needles during the operation of transferring loops of soil from the needles of one needle box of a flat knitting culinary machine to the needles of another needle box according to a predetermined pattern repeat, while loops from the lining thread are knitted on the needles from which to transfer, and on the needles on which the transfer is carried out, a sketch of the footer thread is laid to the transferred soil loop, then the soil loops with the outline of the footer thread are transferred back to the same needles from which they were removed.

Then the next looped row of soil is knitted, stretching the soil loops through the soil loop of the previous loop row and a sketch of the lining thread. As a result, a loop of soil and a turn of the lining thread with double winding of the needle shaft from the hook side are placed on these needles. In this case, all the elements of the loop structure involved in the transfer process are fixed on the needle shaft by the pulling force of the web. The invention is illustrated in the drawing, which shows a method of laying a lining thread in the process of performing the following process cycles.

In the first knitting cycle form a looped row of soil from the thread N _G1 on the needles And ₁ ,

And ₂ , And ₃ , etc. the rear needle bar of a double-circuit cooking machine.

In the second cycle, the loops of soil are transferred from the needles of the rear needle bar to the needles of the front needle bar according to a given pattern repeat with the simultaneous laying of the foot thread H _f . In this case, the transfer is carried out from every second needle of the rear needle bar And ₂ , And ₄ , etc. on the even needles of the front needle bar AND ₂ ', AND ₄ ', etc. Because when transferring the loops, the needle with which the transfer is carried out rises above the complete conclusion, and the needle to which the transfer is carried out rises to an incomplete conclusion, laid at the time of the loop transfer, the lining thread H _f forms on even needles And ₂ , And ₄ , etc. hinges, stretched through the transferred skeletons of soil loops, and on even needles And ₂ ', And ₄ ', etc. to the transferred skeleton of the soil loop lay a sketch of the lining thread H _f .

In the third cycle, the soil loop is transferred with the outline of the lining thread

N _f with even needles of the front needle bar And ₂ ', And ₄ ', etc. back to the same even needles And ₂ , And ₄ , etc. the rear needle bar with which they were removed.

In the fourth cycle of knitting on needles And ₁ , And ₂ , And ₃ , etc. the back of the needle bar form a new looped row of soil from the thread N _G2 , fixing the turn of the footer thread in the soil structure in the form of a sketch.

The reliability of this transfer process is ensured by the fact that all the elements of the loop structure involved in the transfer process are fixed on the needle shaft by the pulling force of the web, whether it be loops formed from a foot thread and hanging on the receiving needle, or outline of the foot loop transferred to these needles alone, but with a loop of soil. As a result of such a transfer on even needles And ₂ , And ₄ , etc. loops of the ground and a loop of the lining thread with double wrap of the needle shaft from the hook side will be located on the rear needle bar.
