Abstract

The invention provides micro-nano-scale regenerated fiber non-woven fabric with moisture conducting and rapid drying properties and a preparation method of the non-woven fabric. The preparation method comprises steps as follows: bamboo strips are soaked in a degumming solution and subjected to steaming, water washing, dividing, reduction, softening and fiber combing under heating and pressurizing conditions, and long natural bamboo fiber and short natural bamboo fiber are obtained; the short natural bamboo fiber is subjected to enzymolysis in cellulase, and bamboo fiber nanowhiskers are obtained; a first absorption layer is formed by the long natural bamboo fiber, the bamboo fiber nanowhiskers are added to a regenerated silk protein solution to form a spinning solution, a transition layer is formed on the surface of the first absorption layer through spinning, long natural bamboo fiber is uniformly laid on the transition layer to form a second absorption layer, gray fabric formed by the first absorption layer, the transition layer and the second absorption layer is subjected to needling reinforcement and hot press forming, and the micro-nano-scale regenerated fiber non-woven fabric with moisture conducting and rapid drying properties is obtained.

Description

technical field [0001] The invention belongs to the technical field of textile materials, and in particular relates to a method for preparing moisture-conducting and quick-drying micro-nano regenerated fiber non-woven fabrics. Background technique [0002] Thermal comfort is the most important reference factor for summer fabrics, and thermal comfort mainly depends on the balance of energy exchange between the heat generated by the human body itself and the heat emitted to the environment. The human body maintains the thermal balance of the body through its own body temperature regulation mechanism, which is Necessary to maintain normal life activities. The loss of moisture on the surface of the human skin is divided into gaseous sweat and liquid sweat. Gaseous sweat refers to the water evaporated from the skin surface by the human body every moment. The conduction of gaseous sweat is mainly through the pores of the fabric, which is closely related to the air permeability of ...
