Description
Technical Field
The invention relates to the field of textile fabrics, in particular to a moisture absorption heating fabric based on functional polyester and a preparation process thereof.
Background
The moisture-absorbing and moisture-permeable fiber is also called high-moisture-absorbing fiber, and generally refers to a fiber which is formed by soaking hydrophobic synthetic fiber into terylene, polypropylene and the like in water and can keep more than 15% of moisture after centrifugal dehydration under certain conditions after physical deformation and chemical modification, so that the high-moisture-absorbing fiber is formed; the fiber can absorb gas phase moisture under the conditions of standard temperature and humidity, and the moisture regain of the fiber is more than 6 percent, so the fiber is called as high moisture absorption fiber. Sweat and sweat discharged from a human body can be rapidly diffused through clothes to keep the skin dry and comfortable. In the discharged sweat, a small part of the sweat is directly discharged from the fabric gaps, which is called as moisture permeation diffusion; most of the fiber is directly absorbed by the fabric fiber, and the fiber is diffused to the surface layer of the fabric and enters the atmosphere through evaporation, which is called moisture absorption and diffusion. The traditional fiber has good moisture absorption and water absorption performance, the synthetic fiber has poor water absorption due to the fact that polymer molecules of the synthetic fiber lack hydrophilic groups, when a human body sweats in a large amount, the comfort of the human body is weakened due to the fact that the moisture absorption speed, the moisture diffusion speed and the evaporation speed of a polymer fiber fabric of the synthetic fiber are not ideal, the traditional method for improving the moisture absorption and the moisture absorption of the synthetic fiber comprises the methods of copolymerization with hydrophilic units, fiber microporosity and the like, the air permeability of the synthetic fiber fabric can be improved to a certain extent, and still some defects exist: due to the increase of porosity, the air permeability is improved, and the heat insulation performance is reduced; the existing improvement for improving the air permeability only aims at single-layer fabric improvement, when the multilayer structure of the fabric is used for improving the heat insulation performance or adding other functions, the thickness and the structure are increased, the fabric structure lacks moisture diffusion gradient, and the air permeability, moisture permeability and drainage performance are reduced; how to research and develop a novel surface fabric for the surface fabric can have perspire and thermal insulation performance concurrently when not moving, can promote the perspire when strenuous exercise, increase the metabolism and get rid of sweat fast, has good actual demand and market prospect.
