Description

Preparation method of water-absorbing and breathable fabric
Technical Field
The invention relates to the field of garment materials, in particular to a preparation method of a water-absorbing breathable fabric.
Background
With the progress of scientific and technological technology and the improvement of life quality of people, the consumption idea of wearing clothes is changed into health and comfort, so that the water absorption and air permeability of the fabric are one of the performances of ideal clothes fabrics, and the fabric becomes a hot point of common attention of consumers and manufacturers. The garment fabric with water absorption and air permeability can absorb moisture and sweat emitted by a human body to the maximum extent, and quickly transmit and diffuse the moisture and sweat, so that the skin is kept clean and dry, and the wearing comfort performance of the garment is improved. Particularly, under the weather conditions of high temperature and high humidity in summer, a large amount of sweat can be produced when people take strenuous exercise, so that the sweat on the surface of the skin is difficult to discharge, and the stuffy feeling is caused; when the human body stops sweating, the fabric is slower in moisture release, and the moisture in the fabric squeezes away the air in the fabric, so that the heat preservation of the fabric is reduced, the skin surface is wet and cold, and the wearing comfort of the fabric is greatly reduced. Therefore, garment materials with good water absorption and air permeability have become a common demand in the garment consumer market. It is well known that cotton fiber is an important natural fiber with a long history and has a place that other products cannot replace. In recent years, although cotton fibers are highly attractive because of their advantages such as good moisture absorption, soft hand, and comfortable wearing, they are significantly weaker than most chemical fibers in moisture permeability, and thus have limited application to high-performance fabrics such as water-absorbent and air-permeable fabrics. At present, most of researches on water-absorbing and air-permeable fabrics at home and abroad are focused on developing functional synthetic fibers and application of the developed functional synthetic fibers, most of the developed new fabrics are focused on synthetic fiber fabrics, and the researches on water-absorbing and air-permeable performances of pure natural fiber fabrics are less touched.
In the prior art, as a chinese patent with an issued publication number of CN 104118162B, a water-absorbing breathable fabric is disclosed, which comprises a fabric body woven by warps and wefts to form a plain weave structure, wherein the warps are hollow PET polyester filaments, the surface of the PET polyester filaments is provided with a plurality of through holes communicated to the hollow cavities inside the PET polyester filaments, zeolite particles are embedded in the wall body of the PET polyester filaments, the wefts are bamboo fiber filaments, and the side portions of the bamboo fiber filaments are provided with a plurality of grooves extending along the extending direction of the bamboo fiber filaments. The fabric has good water absorption and air permeability, can ensure that water attached to the surface of warp threads is quickly absorbed into the fibers to keep the human body fresh and comfortable, but the fabric has insufficient softness and insufficient wearing comfort.
