Problems solved by technology

However, due to the long length of apocynum fiber, it is difficult to degumming. Even after chemical degumming, it still contains a small amount of residual glue, which also includes a certain amount of pectin, hemicellulose and lignin, which makes spinning difficult. yarn quality is relatively poor
[0004] Now commonly used environmentally friendly and comfortable yarns also include colored cotton, viscose fiber, bamboo fiber, Tencel, modal fiber, etc., and most of these fibers have low strength and cannot be degraded

Abstract

The invention discloses a multi-component yarn. The multi-component yarn comprises the following components in percentage by weight: 15 to 45 percent of polyterephthalate-1,3-propylene glycol ester fiber, 15 to 45 percent of polylactic acid fiber and 15 to 45 percent of viscose. The multi-component yarn has high moisture absorption, air permeability, elasticity, fluffy and soft handfeel, high comfortability when contacting with skin, bright color and rich luster in cloth and excellent heat resistance and ultraviolet resistance, is easy to dye, and can be widely applied to textiles, in particular to the textiles for clothes. The invention also discloses a method for preparing the multi-component yarn. By the method, the conventional spinning equipment is fully utilized and a spinning machine does not need to be researched singly, so the spinning difficulty is reduced, the product quality is improved and the method is suitable for industrialized production.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a multi-component yarn and a preparation method thereof. Background technique [0002] Textile is a traditional advantageous industry in my country. In recent years, people have carried out various developments and researches on new textiles from raw materials and processing technologies, and various yarns and fabrics with good comprehensive properties have emerged. Environmental protection, comfort and appearance have always been the focus of people's pursuit. [0003] Environmental protection commonly used at present, comfortable yarn mostly are imitation cotton yarn, apocynum yarn etc., disclose a kind of apocynum yarn that textile is used as in Chinese patent ZL 00129365.6, and it comprises fiber and apocynum fiber, wherein the fiber The mass percent composition is 65%-95%, and the mass percent composition of apocynum fiber is 5%-35%, and described fiber comprises cotton fi...
