Abstract

Disclosed is a method for using a computerized two-needle flat-bed knitting machine to knit a two-sided ridged jacquard knitted fabric. A computerized two-needle flat-bed knitting machine is used to knit a two-sided ridged jacquard pattern having two colors A and B. A yarn (A) and a yarn (B) have different diameters. The yarn (A) of the color A has a large yarn count, and the yarn (B) of the color B has a small yarn count. Knitting density is configured. A two stage stitch employs tight and loose kinking, and kink depths of the yarn (A) and the yarn (B) are respectively controlled by means of a needle cam, so as to respectively adjust knitting rows corresponding to the yarn (A) and the yarn (B) to fall within different kink value ranges. Different knitting row numbers of the yarn (A) and the yarn (B) are configured. The invention forms two-sided ridged jacquard knitted fabric, and ridges on both sides are formed in a single knitting action.

Application number: 202010559168.1, application date: June 18, 2020;

It also claims the priority of the above-mentioned Chinese patent application, and the entire content of the above-mentioned Chinese patent application is hereby incorporated into this application as a reference.

Technical field

The invention relates to a knitting technology, in particular to a method for knitting a double-sided foam jacquard knitting structure on a double-needle bed computerized flat knitting machine.

Background technique

At present, the jacquard organization on the market is divided into two categories, one is single-sided jacquard or double-sided jacquard, but the appearance of both sides is flat. The other type is single-sided foamed jacquard weave. The foam wrinkles are mostly compressed by machine molds to obtain wrinkles, but small foam wrinkles are easy to disperse; or weave it on a double needle bed computerized flat knitting machine. Two kinds of yarns with different elasticity, namely elastic yarn with high shrinkage performance or thermal welding yarn and ordinary yarn are alternately woven to form single-sided creases; or single-sided creases can be woven by expensive four-needle-bed computerized flat knitting machine. However, the four-needle bed computerized flat knitting machine is expensive, and most companies cannot afford the expensive costs.

Summary of the invention

The technical problem solved by the present invention is to provide a double-needle bed computerized flat knitting machine knitting double-sided foam jacquard knitting structure, forming a double-sided foam jacquard knitting structure, and the foam wrinkles on both sides are knitted and formed at one time.

The technical solutions are as follows:

The double-needle computerized flat knitting machine is used to knit double-sided foam jacquard knitting. When the double-needle computer flat knitting machine is used to knit the AB two-color double-sided foam jacquard pattern, the thickness of yarn A and yarn B are different, A Colored yarn A uses a thicker yarn count, and B-color yarn B uses a finer yarn count; set the knitting density; the two-stage mesh uses one loose and one tight, and the yarns are controlled separately by the pressure needle triangle For the bending depth of A and yarn B, adjust the knitting rows corresponding to yarn A and yarn B to different mesh values; set the number of different knitting rows for yarn A and yarn B.

Furthermore, the yarn count, knitting density, and number of knitting rows of yarn A and yarn B are different.

Further, the knitting of the yarn A is smooth on the front and back sides with 4 needle positions on the left and right sides, the middle circulating needle position forms a wrinkle, and the yarn B is smooth on both sides.

Furthermore, the yarn A corresponds to the knitting row size of 55-60, and the yarn B corresponds to the knitting row size of 27-32.

Furthermore, when knitting, 12 strokes in the longitudinal direction constitute 1 cycle, and 12 needle positions in the transverse direction.

Further, the front needle bed of the double needle bed computerized flat knitting machine knits positive stitches, but is not connected with the back needle bed for knitting back stitches.

Furthermore, the double-needle-bed computerized flat knitting machine includes at least a pair of needle beds in front and rear opposite directions, and the yarn guide includes at least two, adopting a single system or a double system.

Compared with the prior art, the technical effects of the present invention include:

The invention utilizes an ordinary double-needle-bed computerized flat knitting machine to form a double-sided foam jacquard knitting structure through three different technical treatments of yarn count, knitting density, and knitting row number of A and B yarns , The foam wrinkles on the front and back sides are woven at one time and do not need to be processed in the subsequent process. It is not easy to disperse in the later period. It not only has a sense of fashion and three-dimensionality, but also because the double-sided foam formed by the A color yarn locks the air inside. The flow of layers, the material has a warmth-keeping effect, and can be used to make knitted jacquard cotton clothes for outer wear in cold winter, filling the gap of knitted cotton clothes in the current market.
