Problems solved by technology

The consumption of polyester fiber in clothing is the largest among all kinds of synthetic fibers, but its hygroscopicity is the worst. Under the condition of temperature of 20°C and relative humidity of 65%, polyester fiber absorbs moisture in a balanced manner. The moisture absorption rate is only 0.4%. Ordinary polyester clothes often make people feel stuffy when worn. Therefore, the research on the moisture absorption and perspiration function of polyester has become one of the hot spots of differential fibers today.

Abstract

The invention relates to a cross-section fiber containing a metal-modified cross-shaped ester compound and a preparation method thereof. The preparation method is: melt-spinning a spinning melt prepared by melting and blending functional masterbatches and polyester chips. Cross-section fibers containing metal-modified cross-shaped ester compounds are obtained. The functional masterbatch contains metal-modified cross-shaped ester compounds. The metal-modified cross-shaped ester compounds are network polymers formed by cross-linking cross-shaped ester compounds and metal ions. , The metal-modified cruciform ester compound is insoluble and infusible, insoluble in organic solvent I below 80°C, and does not melt in the range from room temperature to T, and T≥380°C. The wicking height of the fabric made from the cross-section fiber containing the metal-modified cross-shaped ester compound is 150-250 mm within 10 minutes. The method of the invention is simple to operate, and the finally prepared fiber has excellent functions of flame retardancy, antibacterial and moisture absorption and perspiration.

Description

technical field [0001] The invention belongs to the technical field of functional fibers, and relates to a cross-section fiber containing a metal-modified cross-shaped ester compound and a preparation method thereof. Background technique [0002] Functional fibers, differential fibers and high-performance fibers are the main development directions of technological innovation in the traditional textile industry. Functional fiber refers to a new type of fiber that has some special function in addition to the physical and mechanical properties of ordinary fibers. In daily life, fire accidents caused by burning textiles will bring casualties and property losses to people. Therefore, the use of flame-retardant work clothes and home textiles has become an urgent need for people. [0003] Moisture-absorbing and sweat-wicking fibers generally use the capillary phenomenon produced by the micro-grooves on the surface of the fibers to make sweat quickly migrate to the surface of the f...
