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 ester and a preparation method of the cross section fiber. The preparation method comprises the following steps: performing melt blending on a functional master batch and a polyester chip to prepare spinning melt, and performing melt spinning, thereby obtaining the cross section fiber containing the metal modified cross ester. The functional master batch contains the metal modified cross ester; the metal modified cross ester is a network polymer formed by cross-linking a cross ester and a metal ion; and the metalmodified cross ester has insoluble and non-melting characteristics, cannot be dissolved into an organic solvent I at a temperature of 80 DEG C or below, and is not melted in a range from room temperature to T, wherein the temperature T is more than or equal to 380 DEG C. A fabric prepared from the cross section fiber containing the metal modified cross ester has a wicking height of 150-250mm within 10 minutes. The method disclosed by the invention is simple in operation, and the finally prepared fiber has excellent flame-retardant, antibacterial and moisture absorption and sweat releasing functions.

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...
