Abstract

The invention relates to high-strength hot air seaweed membrane cloth and further relates to a preparation method of the high-strength hot air seaweed membrane cloth. The preparation method of the high-strength hot air seaweed membrane cloth comprises the following steps that (1) a sodium alginate spinning solution is prepared; (2) the spinning solution is introduced into a first coagulating bathand drafted to obtain a nascent fiber; (3) the nascent fiber is washed through distilled water, introduced into a second coagulating bath and drafted; (4) washing is conducted through a water bath; (5) the fiber obtained in the fourth step is soaked in a chitosan solution, then moisture is extruded out, drying is conducted until the constant weight is achieved, and a sodium alginate fiber is obtained; (6) the sodium alginate fiber obtained in the fifth step is mixed with an ES fiber and a silk fiber according to the mass ratio of (70-80):(10-12):(5-6), and then through hot air gluing and cooling formation, the cloth is obtained. The hot air seaweed membrane cloth has the advantages of the sodium alginate fiber, the silk fiber and a hot air gluing product, is high in strength and does not easily deform.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a high-strength hot-air seaweed membrane cloth, and also relates to a preparation method of the above-mentioned high-strength hot-air seaweed membrane cloth. Background technique [0002] Hot-air non-woven fabric belongs to one of hot-air bonded (hot-rolled, hot-air) non-woven fabrics. After the fibers are carded, the hot air on the drying equipment is used to penetrate the fiber web to make it bonded by heating. of non-woven fabrics. Hot rolling bonding refers to a thermal bonding method in which a pair of hot rollers are used to heat the fiber web and a certain pressure is applied at the same time; hot air bonding refers to the use of hot air to penetrate the fiber web on the drying equipment to heat and melt it to form a bond. combined production methods. Hot air bonded products have the characteristics of high bulkiness, good elasticity, soft hand feeling, strong warmth retention, g...
