Method for preparing high-strength silver-ion antibacterial blended yarns

Abstract

The invention provides a method for preparing high-strength silver-ion antibacterial blended yarns. The method includes the following steps that PTT fibers are subjected to heating pretreatment, then the PTT fibers and silver-ion aramid fibers are doubled to form yarn cores, in the process that the PTT fibers and the silver-ion aramid fibers are doubled and twisted to form the yarn cores, the twist direction of the yarn cores and the twist direction of the yarn cores in the following coating process is opposite, and the twist degree of the yarn cores is equal to that of the yarn cores in the following coating process; the friction spinning coating technology is adopted, outer layers are coated with yarns, coating is carried out in the axis direction of the yarn cores in a spiral mode, and the coating degree is controlled 1,000 circles / meter. The good coating effect is achieved, the fuzz ball phenomenon generated in the fiber using process can be prevented, and the tensile strength, the toughness and the antibacterial performance of the yarns can be improved.

Description

technical field [0001] The invention belongs to the field of textile technology, and in particular relates to a preparation method of high-strength silver ion antibacterial blended yarn. Background technique [0002] Covered yarn is an excellent textile material with the characteristics of good elasticity, no pressure, stable size, good recovery, soft texture, comfortable movement, etc. It provides high-grade raw materials for textile, knitting, hosiery, clothing and other fields. Its production process is to twist and wrap the fiber on the yarn core. However, in the process of wrapping and twisting, it will also play a certain twisting effect on the yarn core. In order to prevent the yarn core from returning to its original state after twisting and causing the covered yarn to shrink, most of the covered yarns are treated with heat preservation and setting technology, but this treatment method only sets the yarn shape, and the fibers inside are still in a twisted state. sta...

Problems solved by technology

In order to prevent the yarn core from returning to its original state after twisting and causing the covered yarn to shrink, most of the covered yarns are treated with heat preservation and setting technology, but this treatment method only sets the yarn shape, and the fibers inside are still in a twisted state. state, so that the tensile strength and toughness of the yarn are greatly affected, and because the existing covered yarn has a small covering degree, the phenomenon that the core of the yarn is often exposed, resulting in the inner core of the yarn being affected Wear and tear will easily cause the performance of the internal yarn core to be lost too quickly; in addition, with the improvement of material living standards, people's requirements for textiles are no longer limited to the original basic characteristics such as warmth and comfort. People also hope that they have health care, Safety and other special functions, such as antibacterial, anti-concealment, negative ions, far infrared, anti-ultraviolet, anti-virus, flame retardant, anti-electromagnetic radiation, magnetic therapy, fragrance, moisture absorption and perspiration, oil-proof and waterproof, etc. Among them, anti-bacterial fabrics can be widely used in hospitals. , hotels, family sheets, quilt covers, blankets, napkins, towels, shoe linings, sofa releases, curtains, medical professional wear, food and service industry work clothes, military clothing, bandages, gauze, etc., have great social significance
