Method for manufacturing seamless knitted dress employing PTT fiber

Abstract

The invention relates to a production method of seamless knitted garments adopting polytrimethylene terephthalate fibre, including the steps of (1) selecting raw materials according to product purposes, requirement of style and performance and characteristics of the raw materials; (2) establishing textile technology and weaving garment blank by a knitting machine; (3) according to colored woven garment and grey garment sorting and making a finishing process flow; (4) confirming key finishing process parameter. The finished PTT seamless knitted garments by adopting the invention have soft texture, good extensibility, good rebound elasticity, and are comfortable and beautiful; the elasticity in particular lasts long; compared with the existing products made of nylon and spandex, the product has incomparable advantage in chlorine fastness, sun fastness and high-temperature processing resistance, etc., which leads possible extended application of the seamless knitted garments to high grade swimwear, sportswear, high temperature printing, etc.

Description

technical field [0001] The invention belongs to the field of textiles, and relates to the application technology of a new type of polyester (polytrimethylene terephthalate, PTT for short) fiber in seamless knitted garments, especially fiber raw material matching and specification selection, knitting process and finishing Process technology, as well as the design technology of finished product elasticity, hand feeling, chlorine bleaching resistance, light resistance and other properties. Background technique [0002] Seamless knitted garments are knitted garments with a three-dimensional surface shape made of fixed warps and needles, changing tissues, raw materials and knitting processes. The torso is generally not cut and stitched and provincial stitches, commonly known as one-time forming clothing. Compared with the three-dimensional surface garments cut and sewn from ordinary knitted fabrics or woven fabrics, seamless knitted garments have almost no seams, and are more fi...

Problems solved by technology

However, the application of this new fiber is not a simple replacement of raw materials, and a series of technical problems need to be solved, otherwise it will not be possible to produce products with excellent performance and accepted by the market

For example, when weaving seamless knitted garments with PTT DTY filaments instead of nylon DTY filaments, the phenomenon of weft skew appears, and the PTT seamless knitted garments made by the existing finishing process are generally insufficient in elasticity and hard to the touch. and many more

The former is caused by the residual torsional stress on the PTT DTY filament, which is the embodiment of the shape memory function of the PTT polymer; the latter is caused by the failure of the finishing process and the insufficient recovery of the residual deformation in the PTT fiber.
