Preparation method of knitted collar with anti-curling characteristic

Abstract

The invention relates to a preparation method of a knitted collar with an anti-curling characteristic. The preparation method comprises the following steps: firstly, knitting a collar with thermoplastic elastomer yarn introduced into a collar corner area, then paving the collar, and carrying out compression heat setting on the whole collar; and adopting at least three yarn nozzles A (main yarn isthreaded), B1 and B2 (thermoplastic elastomer yarn is threaded in both B1 and B2) for knitting. The knitting process is as follows: A is used for knitting rib stitch, when a first transverse row is knitted, B1 and A are controlled to jointly knit 1st to a1st knitting needles from the left; when an i-th transverse row is knitted, B1 and A are controlled to jointly knit 1st to ai-th knitting needlesfrom the left, and B2 and A are controlled to jointly knit the 1st to aj-th knitting needles from the right, wherein i is part or all positive integers in the range of [2,v], v / w (overall transverserow number) is less than or equal to 50%, j is the serial number of the transverse row in which B1 participates in knitting the last time before the i-th transverse row is knitted, ai is smaller thanor equal to aj; and when the (v+1)-th transverse row to the w-th transverse row are knitted, A is adopted for continuously knitting the rib stitch, and meanwhile B1 and B2 are controlled to retreat from a knitting area. The method is simple, and the manufactured collar is excellent in comfort and edge curling resistance.

Description

technical field [0001] The invention belongs to the technical field of collars, and relates to a method for locally introducing thermoplastic elastomer yarns to realize the curling resistance of collars. Background technique [0002] The collar is a clothing part that is attached to the neck of the human body and plays a role of protection and decoration. At present, there are two main requirements for the performance of knitted collars: one is the contact comfort when wearing, keeping warm in winter and smooth in summer; Holds its shape well without curling or wrinkling, keeping its shape beautiful. The collar corners of the collar in the prior art tend to curl up, so the shape of the collar becomes worse after wearing for a period of time. [0003] Knitted collars have been able to achieve good contact comfort, such as collars made of cotton, regenerated cellulose fibers and other materials. However, the collars made of raw materials such as cotton and regenerated cellu...

Problems solved by technology

However, the collars made of raw materials such as cotton and regenerated cellulose fibers generally have curls and wrinkles after about 5 to 10 washes on the market, which cannot keep the original smoothness and stiffness of the collars. Curl occurs at the collar corners of collars, so if the curl can be addressed from the collar corners, then the appearance of the collar will directly improve

[0004] In the prior art, another part of the fabric with memory function is usually directly sewed on the collar corner of the collar, or inserts are added to reinforce the collar corner, so as to achieve the function of anti-curling of the collar corner, so that the collar fabric is stiff and shape-retaining, such as the patent Document 1 (publication number CN209314981U) sews memory collar corners on the front side of the lapel. The memory collar corners are composed of PTT and memory foam, both of which have the function of shape memory, which can solve the problem that the collar corners of the collar are easy to collapse and make the shape of the collar Poor problem, although this method can strengthen the shape-preserving effect at the collar corner, it affects the uniformity and consistency of the appearance of the collar; A pad is set near the collar tip, the shape of the pad matches the shape of the collar tip, and the shirt collar is kept in shape, preventing the collar corner from curling outward; Patent Document 3 (publication number CN203353746U) adds an iron sheet outside the collar tip The method makes the collar stronger and more stylish, easy and quick to install, and can withstand multiple washings without deformation; Patent Document 4 (publication number CN 203505594U) adds reinforcing parts to the collar corner so that the collar corner cannot be bent and wrinkled, so as to maintain the collar. Shape effect; Patent Document 5 (publication number CN202949976U) sets inserts on the back of the lapel along the corner bisector of the collar tip, and the addition of the inserts ensures that the collar corners are stiff and smooth; The shape of the collar angle is more suitable for sewing collars of woven fabrics, while knitted collars are integrally formed, the steps of adding reinforcement pieces are cumbersome, and the reinforcement parts are easy to be exposed, which not only increases the cost but also affects the appearance of the fabric

[0005] In the prior art, elastic memory filaments are usually interwoven with other yarns to form memory elastic knitted fabrics, so as to achieve the anti-curling function of the collar corners, making the collar fabric stiff and good in shape retention, for example, patent document 6 (CN110438634A) Adopt the technique of plaiting to weave ribbed fabric, this technology needs to introduce elastomeric yarn such as TPU with the mode of plaiting in the whole collar of collar, then carry out tense heat setting to it again, TPU plays in the whole collar Skeleton support can make a high-conformity knitted collar, but the use of elastomer yarn for the entire collar will make the collar poor in air permeability, high in bending stiffness, and poor in wearing comfort, and because the elastomer yarn is expensive, the cost of the collar is relatively high
