Problems solved by technology

Among them, high-density fabrics are made of microfibers and other synthetic fibers, which have high water vapor permeability, and have certain water resistance after water-repellent finishing. Its advantages are high moisture permeability, softness and suspense. Good durability, but its water pressure resistance is low, dyeing and finishing processing is difficult, and the fabric is also poor in tear resistance and abrasion resistance
[0005] Coated fabric is a layer of hydrophilic coating on the surface of traditional fabrics. Since the coating covers all the gaps in the fabric, it has a certain degree of water resistance, but because of the poor durability of the coating, the coating will be damaged as the number of washings increases. fall off, thus losing the corresponding waterproof performance

Abstract

The invention discloses a waterproof fabric material and a preparation method thereof. The waterproof fabric material is prepared from components in parts by weight as follows: 65-80 parts of polylactic acid, 28-38 parts of natural fiber, 2-4 parts of polyethylene wax, 1-2 parts of diethyl phthalate, 0.2-1.8 parts of sodium sulfate, 0.5-1.2 parts of octadecyl bis-quaternary ammonium salt and 0.5-1 part of polyvinylpyrrolidone. The invention further provides a preparation method of the waterproof fabric material. The method comprises steps as follows: the components are added to a shearing machine to be mixed, an acidity regulator is added to adjust the pH, the mixture is uniformly mixed, melt at the temperature of 195-220 DEG C under the airtight condition, subjected to spinning at the spinning speed of 1,500-2,000 m / min and subjected to drawing treatment, and the waterproof fabric material is prepared.

Description

Technical field [0001] The invention belongs to the field of textile materials, and particularly relates to a waterproof fabric material and a preparation method thereof. Background technique [0002] Textile fibers can be divided into natural fibers and chemical fibers. Among them, chemical fibers include regenerated fibers, synthetic fibers and inorganic fibers. [0003] With the continuous improvement of people’s living standards, new requirements for clothes for different occasions have been put forward, especially outdoor sports, as a healthy and fashionable way of leisure, are becoming more and more popular with more people. At the same time, the performance of outdoor clothing is also improved. In order to meet higher requirements, such as waterproof, moisture permeability, windproof, warmth and so on. [0004] Waterproof and moisture-permeable fabric, also called breathable fabric, is a product that integrates waterproof, moisture-permeable, windproof and warmth. Waterproo...
