Problems solved by technology

[0004] In recent years, the application range of the full-dull network elastic yarn made of PET has gradually increased. However, the glossiness of the fully-dull network elastic yarn prepared by the prior art is still high, and it is difficult to achieve the daily required matting effect. The oil agent used in the process volatilizes quickly and is easy to bond on the surface of the fiber, resulting in a high unevenness of the fiber and affecting the performance of the fiber

Abstract

The invention relates to a complete-extinction network stretch yarn and a preparation method thereof. The preparation method comprises the following steps: metering, extruding, cooling, oiling and winding polyester melt to obtain POY yarns, enabling the POY yarns to pass through a yarn guide pipe and a network, heating and stretching the POY yarns, false twisting the POY yarns, thermosetting, winding molding the POY yarns to obtain DTY yarns, thus obtaining the complete-extinction network stretch yarns, wherein oil for oiling comprises crown ether, the content of the crown ether is 67.30 to 85.58 percent by weight, a matt agent is dispersed in the polyester melt, the matt agent is a mixture of amorphous titanium dioxide and amorphous silicon dioxide or a mixture of calcium carbonate and amorphous silicon dioxide. The gloss of the prepared complete-extinction network stretch yarn is less than 20 percent, a curling shrinkage rate is greater than or equal to 35 percent, and the curling stability is 75 to 85 percent. The method is simple and reasonable, and the prepared complete-extinction network stretch yarn has the advantages of complete extinction and good performance and is high in popularization value.

Description

technical field [0001] The invention belongs to the field of fiber preparation, and relates to a full-dull network elastic yarn and a preparation method thereof. Background technique [0002] Since the appearance of polyethylene terephthalate (PET) fiber, it has developed rapidly because of its excellent performance, and its output has become the crown of synthetic fiber in the world. Polyester fiber has a series of excellent properties such as high breaking strength, high elastic modulus, moderate resilience, excellent heat setting performance, good heat resistance and light resistance, acid resistance, alkali resistance and corrosion resistance, and the fabric prepared from it has wrinkle resistance. And crispness and other advantages, so polyester fiber is widely used in clothing and home textiles and other fields. [0003] Due to the small dielectric constant, low moisture regain and high friction coefficient of most PET fibers, spinning oil must be used in the spinning...
