Abstract

The invention discloses a method for producing cool sense honeycomb fibers. The method comprises the following steps: adding high-thermal-conductivity nano silicon carbide powder into master batch or pulp of honeycomb fibers according to a weight ratio of 1-2 percent, uniformly stirring, performing steam explosion on yarns, and preparing the honeycomb fibers. The invention discloses a technical method for improving a cool effect of the honeycomb fibers by changing heat-conducting property of thermal resistance enhanced fibers of the honeycomb fibers by using silicon carbide and the like, and the high-thermal-conductivity nano silicon carbide powder is added into the honeycomb fibers according to a ratio being about 1-2 percent, so that the thermal conductivity of the fibers can be improved from the original 0.1 to 2.0-3.8, and the thermal conductivity is improved by 20-40 times. The method has the characteristics that the addition amount is low, an effect of obviously improving the mechanical property of the product is achieved, the heat-conducting effect is obviously improved, and the like. Moreover, the original excellent performance of the honeycomb fibers is not changed. The clothing made of the fibers has obvious low thermal resistance and low damp obstruction characteristics, and the fiber is a special cool fiber.

Description

technical field [0001] The invention specifically relates to a production method of cool-feeling honeycomb fiber. Background technique [0002] The fabric made of honeycomb structure fiber does not need to be finished (that is, it does not need to use any chemical additives to finish the fabric to achieve the purpose of moisture absorption and quick drying, anti-pilling and soft and lubricating), and the more it is used, the softer it is. Very good dimensional stability, no shrinkage and deformation. Therefore, it can not only greatly reduce the pollution to the environment caused by the discharge of a large number of chemical additives due to the need for finishing, but more importantly, it can protect the human skin from the direct damage of chemical substances attached to the clothes. High safety performance. According to the actual operation test, the fabric made of honeycomb structure fiber is compared with the cotton fabric, the moisture absorption speed is 1~2 times...
