Problems solved by technology

Wool yarns in the prior art generally use each yarn to be arranged in one or two coils in a course, and then transferred to the next course to form coils, and are arranged in the weft direction or radial direction to form a weaving structure, but because the wool yarn is spun The twist direction of single yarn or ply yarn, the tensile strength of wool yarn is small, and the weaving is loose at the same time, and it is easy to be pulled by accident to transfer the coil. As the strength increases, the wool yarn fiber becomes stiff, resulting in insufficient stretch and elasticity of the finished product. It is difficult to obtain wool knitted fabric products with suitable linear density, strength and extensibility only by twisting, which affects the comfort and durability of wool knitted fabrics.

Abstract

The invention relates to a knitting process of elastic wool knitted fabrics. The knitting process is as follows: yarn soaking, yarn feeding, loop removal, needle narrowing, yarn lapping, yarn bending, looping, and 1 to 3 stitches between adjacent knitting needles. Needle selection does not participate in knitting, and repeat steps to form a single-pass knitting. 3*N single-pass stitches are used as a complete weave for circular knitting. The odd-numbered routes that are divided by 3 times are knitted with wool yarn front loops, and the even-numbered routes that are divided by 3 multiples are knitted with wool yarn reverse loops. , a multiple of 3 is woven with high-elastic fibers, N is an integer above 1, and a knitted fabric is formed. The knitted fabric is soaked in warm water, dehydrated and dried for relaxation treatment, and then placed on a heat setting machine to expand and set. Finally, Knitted fabrics are stitched or woven to obtain cap knitted fabrics. The laying positions of the wool yarn and the high-elastic fiber are different, so that the coil sinker arc is stretched into a loop. The high-elastic fiber bound wool yarn has good covering weaving performance, stable tension, and no breaks Hair phenomenon, high dimensional stability, can improve the elongation and elasticity of wool knitted fabrics.

Description

technical field [0001] The invention relates to a knitting process of elastic wool knitted fabric, which belongs to the technical field of wool knitted fabric production. Background technique [0002] Wool knitted fabrics are weft-knitted or warp-knitted fabrics formed by using knitting needles to form wool yarn or wool-containing blended yarn into loops, and then passing the loops together, including sweaters, gloves, coats, scarves, etc. , Widely used in production and life convenience. Wool yarns in the prior art generally use each yarn to be arranged in one or two coils in a course, and then transferred to the next course to form coils, and are arranged in the weft direction or radial direction to form a weaving structure, but because the wool yarn is spun The twist direction of single yarn or ply yarn, the tensile strength of wool yarn is small, and the weaving is loose at the same time, and it is easy to be pulled by accident to transfer the coil. As the strength incr...
