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 conventional polyester fabrics is used, the PTT filament and other fiber Composite fabrics cannot meet the expected style requirements such as elasticity and feel; the design of a fabric with excellent performance, especially the design of composite fabrics with new fibers, must fully consider its dyeing and finishing performance, or take dyeing and finishing performance as a fabric design In order to give full play to the excellent properties of various fibers, we can design and produce ideal novel fabrics

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 / ...
