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 kni

Embodiment 1

[0051] The PTT / PET two-component side-by-side composite filament with a specification of 83dtex / 32F is used as the ground yarn, accounting for 35.0% by weight of the raw material; the modal cotton yarn with a count of 40 English is used as the veil, accounting for 65% of the total weight of the raw material. The chest, waist, and abdomen are woven with different tissues into a waist dress blank. Finishing process: pot steaming-soaping, washing-dyeing-softening-ironing. Key finishing process: ①Pot steaming temperature: 90°C, time 60 minutes; ②Dyeing temperature: 98°C, heat preservation for 30 minutes.

Embodiment 2

[0053] The PTT / PET two-component side-by-side composite filament with a specification of 44dtex / 32F is used as the ground yarn, accounting for 30% of the weight of the raw material; the nylon elastic yarn of 78dtex / 68F is used as the veil, accounting for 70% of the weight of the raw material. All the other are woven into boxer garment blanks according to the existing technology. Finishing process: pot steaming-soaping, washing-dyeing-softening-ironing. The key finishing process is the same as in Example 1.

Embodiment 3

[0055] 55dtex / 32F PTT / PET two-component side-by-side composite filaments, accounting for 23% of the weight of raw materials; brown colored cotton yarns of 40 British counts and white cotton yarns of the same count are arranged at intervals as veils, each accounting for 38.5% of the total weight %. The rest are woven into colored cotton underwear blanks according to the existing technology. Finishing process: pot steaming-soaping, washing-shrinking-softening-ironing. Key finishing process: ①Pot steaming temperature: 75°C, time 40 minutes; ②Shrinking process: from normal temperature to 75°C, constant temperature for 30 minutes.

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...
