Problems solved by technology

For the development of PTT fibers, many of them are currently blending short fibers with short fibers such as cotton into yarns. Unfortunately, this processing method cannot give full play to the excellent elasticity of PTT. Compared with the previous polyester / Cotton blended fabrics have no obvious advantages; at the same time, in the dyeing and finishing of PTT filament and other fiber composite fabrics, if the processing technology cannot be effectively designed, or the dyeing and finishing process of

Example Embodiment

[0032] Example 1

[0033] Design and preparation method of PTT filament / tencel staple fiber single yarn covered composite weft fabric

[0034] Raw material combination: warp yarn: 9.8×2tex G100 Tencel yarn, weft yarn: 83.3dtex PTT DTY filament and 9.8tex A100 / G100(50 / 50) Tencel single yarn hollow spindle covered composite yarn;

[0035] Weaving parameter design: Calculated according to the wet heat shrinkage rate of 22% in the pre-scouring process, the change of the density is: the upper machine passes through 402 roots / 10cm, the lower machine passes through the density 410 roots / 10cm, and the wet heat shrinks through the density 525 roots / 10cm , The warp density after 4% heat setting is 502 pieces / 10cm; the width of the fabric is changed: the width of the upper machine is 183.5cm, the width of the lower machine is 180cm, the wet heat shrinks 140cm, and the 4% heat sets 145.6cm.

[0036] Therefore, for the finished fabric with a warp density of 500 pieces / 10cm and a width of 150cm, th...

Abstract

The invention provides a method for designing and manufacturing a textile fabric. Polytrimethylene terephthalate (PTT) filament/staple single yarns are manufactured into a novel fiber composite garment fabric by various composite modes such as wrapping, networking and the like, wherein the fabric can exert excellent elasticity of the PTT filaments, has excellent properties of luster, softness, comfortableness and the like of staple single yarns such as mercerized cotton, tencel and the like, has the special effects of wrapped and networked composite yarns, and has excellent performance and novel style; and the method combines weaving parameter design and pretreatment shrinkage, stretching and heat setting process control and the like, and comprises proper raw material preparation, weaving parameter selection, dyeing and after treatment process.

Description

【Technical field】 [0001] The invention relates to the technical field of composite yarn fabrics, in particular to a design and preparation method of PTT filament / short fiber single yarn composite yarn fabrics, including fabric design and dyeing and finishing processing. 【Background technique】 [0002] At present, the various textile fibers used each have their own excellent characteristics, such as PTT filament with good elasticity, tencel short fiber and mercerized cotton fiber with soft, fluffy feel and excellent luster. If their excellent characteristics are effectively Combined together, we can develop textile fabrics that have both the excellent properties of various fibers and even exhibit better performance. For the development of PTT fibers, many of them are currently blending short fibers with short fibers such as cotton into yarns. Unfortunately, this processing method cannot give full play to the excellent elasticity of PTT. Compared with the previous polyester / ...
