Description
Technical Field
The invention relates to the technical field of textiles, in particular to terylene/sea-island fiber non-elastic core spun yarn and fabric thereof.
Background
The core spun yarn, also called composite yarn or cladding yarn, is a yarn composed of two or more kinds of fibers. The composite fiber is generally twisted and spun by taking the synthetic fiber filaments as core filaments and the short-covered fibers, and has the excellent properties of the synthetic fiber filaments and the short-covered fibers. The polyester filament yarn has the characteristics of high strength, good heat resistance and good wear resistance, and is often used as a core yarn of the core spun yarn. However, the moisture absorption of the polyester filament yarn is very poor, and the moisture regain is only about 0.4%, so that the polyester textile has stuffiness when in use, is easy to be charged with static electricity, and is close-fitting and uncomfortable to wear.
In order to improve the hygroscopicity of the polyester filaments, the polyester filaments can be selected to be physically modified or can be selected to be chemically modified. Wherein, the physical modification means that short fibers with high hygroscopicity are selected to be coated on polyester filaments, for example, cotton fibers are selected to be coated on the polyester filaments, so as to obtain core spun yarns with good hygroscopicity; the chemical modification refers to introducing hydrophilic groups by adopting a graft copolymerization method, and the hygroscopicity of the polyester filaments is directly improved.

The core-spun yarns obtained in examples 1 to 5 and comparative example 1 were made into fabrics according to the same weaving process, and the fabrics in examples 1 to 5 and comparative example 1 were subjected to a moisture regain test according to "GB/T9995-1997 determination of moisture regain of textile material oven drying method"; meanwhile, according to the section 3 of evaluation of the antibacterial property of the textile of GB/T20994.3-2008: the fabrics in examples 1 to 5 and comparative example 1 were tested for antibacterial property by the shaking method, and the antibacterial rate of the fabrics after washing 20 times was tested by the washing method using a washing fastness tester.
