Problems solved by technology

With the advancement of science and technology, the requirements of the working environment and the continuous development of society, people's requirements for cleaning cloth products in the process of use have been continuously improved, and wood pulp composite spunlace cloth has also begun to penetrate into civilian fields such as disposable towels and household cleaning. , the traditional wood pulp composite spunlace cloth has poor performance due to its high surface density, unfull hand feel, smooth cloth surface structure, and low dust holding capacity. The technology of mechanical embossing and wrinkling has appeared on the market
Mechanical embossing wrinkling is obtained by first producing wood pulp composite spunlace cloth, and then destroying the original fabric surface structure by mechanical embossing wrinkling roller rolling. The strength and wear resistance of the product are much lost, and there is a need Problems such as more energy consumption and a decrease in product strength, swarf rate and other indicators

Abstract

The invention discloses a high-efficiency and energy-saving creped wood pulp composite spunlace cloth and a preparation method thereof. The method includes the following steps: fiber feeding→mixing→coarse opening→fine opening→carding into a web→fiber web spunlace→wood pulp spunlace compounding→hot air penetrating through the cylinder, drying and wrinkling→coiling→slitting Package. The invention combines the spunlace forming technology with the high-efficiency rotary screen drying and wrinkling technology, and the produced high-efficiency and energy-saving wrinkled wood pulp composite spunlace cloth can effectively increase the softness and wrinkling feeling of the cloth surface, and the hand feel is thicker when used. , Increase the friction between it and the object to be wiped, can better wipe the surface of the object, and it has good water and oil absorption, easy to use, excellent performance and so on.

Description

technical field [0001] The invention relates to a high-efficiency and energy-saving creped wood pulp composite spunlace cloth and a preparation method thereof, belonging to the field of spunlace non-woven fabrics.
