Problems solved by technology

In recent years, it has been reported that inorganic nanomaterials with high thermal conductivity are introduced into polyester fibers with special-shaped cross-sections. The thermal conductivity of organic polymers is poor. The introduction of materials with high thermal conductivity can increase the heat conduction rate of fibers, but the thermal conductivity of the fibers Ability cannot surpass the thermal conductivity of inorganic nanomaterials

Abstract

The invention discloses a polyester fiber with heat-conduction and moisture-conduction functions and a production method of the polyester fiber. The polyester fiber is prepared from following raw materials in percentage by weight: 0.5-5% of modified nano inorganic silicate and 95-99.5% of polyester. The production method comprises the following steps: crushing the inorganic silicate and sieving to obtain powder with nano size; carrying out surface organic treatment on the powder; and drying the organically-treated silicate nano powder and the polyester and then carrying out fusing and spinning to obtain the polyester fiber with an abnormal section and the heat-conduction and moisture-conduction functions. According to the polyester fiber, the modified nano inorganic silicate is adopted to be used as a main additive with a cooling function and an abnormal section spinning technology is combined to prepare the polyester fiber with the heat-conduction and moisture-conduction functions; the synergistic effect of the modified nano inorganic silicate and the abnormal section spinning technology enables the heat-conduction capability of the polyester fiber to be higher than that of spherical nano materials, so that the good cooling, sweat absorption and quick drying effects are realized; the polyester fiber has a wide application in the aspects of summer clothes, sports wears and the like.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a polyester fiber with heat and moisture conduction functions and a manufacturing method thereof. Background technique [0002] With the change of consumption concepts, people's requirements for clothing are not only fashionable, but also pay more attention to the inner comfort and functionality of clothing. For cool comfort, the fibers of woven clothing are usually required to have good thermal conductivity and moisture conductivity, which can quickly dissipate body heat and sweat, and keep the fabric in contact with the skin dry, giving people a comfortable feeling. Polyester fiber (polyester) has almost no hydrophilic groups, and sweat is not easily absorbed by the fiber but remains between the skin and the fiber, causing sticky and stuffy feeling when worn. Therefore, the research on improving the cool comfort of polyester fiber has attracted much attention from the scientific and in...
