Light absorption heating blended yarn

Abstract

The invention discloses a light absorption heating blended yarn which is prepared from, in weight percent, 20-30% of cotton fibers, 30-40% of nano-heating acrylic fiber blended short fibers, 15-25% ofhollow polyester fibers and 5-35% of spandex fibers. The preparation process of the nano-heating acrylic fiber blended short fibers includes the steps: blending nano-ceramic particles, nano-volcanicrock powder and acrylic fiber spinning liquid to prepare the short fibers, and then blending the short fibers with the cotton fibers and polypropylene fibers to obtain nano-ceramic acrylic fiber blended short fibers; interweaving and blending the nano-ceramic acrylic fiber blended short fibers, the cotton fibers, the hollow polyester fibers and the spandex fibers according to the weight ratio (g / g) to obtain the light absorption heating blended yarn. The prepared light absorption heating blended yarn is gradually heated under illumination, the temperature of the yarn is 4-5 DEG C higher than that of a general fabric after illumination for 30 minutes, the yarn fabric has good light absorption heating performances, warmth retention ratio reaches 19%-21%, heat transfer coefficient is within 40.35-54.23, and the warmth retention property of the yarn fabric is superior to that of the general fabric.

Description

technical field [0001] The invention relates to the technical field of yarns, in particular to a light-absorbing and heat-generating blended yarn. Background technique [0002] With the rapid development of domestic and foreign fabric markets in recent years, the traditional demand for fabrics can no longer meet the diversified needs of consumers, and more and more functional fabrics have been favored by consumers. For fabrics with heating function, the most studied ones are mainly divided into moisture-absorbing and heating fabrics and light-absorbing and heating fabrics. Among them, the moisture absorption and heating function is through the design of the fabric structure, so that the water molecules after the moisture absorption of the fabric move violently inside the fabric and convert kinetic energy into heat energy to play a heating role. As for light-absorbing and heat-generating fabrics, it is mainly divided into the following situations: the first one uses light-ab...

Problems solved by technology

As for light-absorbing and heat-generating fabrics, it is mainly divided into the following situations: the first one uses light-absorbing and heat-emitting fibers for weaving. Absorb visible light and infrared rays in solar radiation and convert them into heat energy. Polyacrylonitrile fibers are obtained by adding far-infrared ceramic powder and zirconium carbide particles to obtain polyacrylonitrile-based solar energy storage heating fibers. The currently developed ones have light-absorbing and heating properties. The yarns are all prepared by adding particles with infrared absorption properties into the matrix fiber solution. The temperature of the woven fabric is 2-8°C higher than that of ordinary fabrics on sunny days. However, this method has seriously affected the breathability and moisture permeability of the fabric, and the quality of the fabric has also declined with the increase in the number of washings. The light-absorbing and heating effect and thermal insulation performance of the light-absorbing and heating blended yarn still need to be further improved
