A composite cloth of ultrafine denier viscose fiber and lyocell fiber and its preparation process

Abstract

The invention relates to a composite cloth of ultrafine denier viscose fiber and lyocell fiber. The composite cloth is made of a reticular fiber layer and a base cloth, and the mass ratio of the reticular fiber layer to the base cloth is 55:45. The reticular fiber layer is formed by wet method of superfine denier viscose fiber slurry; the base cloth is a nonwoven cloth made of lyocell fiber. In the first step, the ultrafine viscose fiber is processed into dry paper. This process step is transferred to the wet papermaking process to speed up the forming step, and the formed ultrafine viscose fiber is uniform and smooth as a whole. Combined with the spunlace composite process, the two main raw material parts can be fully composited and linked. Composite cloth finished product grammage 33-35g / m prepared by the present invention 2 , Thickness 0.21~0.24mm, fine and dense surface style, soft and strong cotton, translucent after soaking in water, only showing the characteristics of yarn, at the same time, it has fast water absorption, good anti-mildew and anti-moth effects, excellent breathable and hygroscopicity, keeps Good moisture, thick cotton texture and other properties.

Description

technical field [0001] The invention relates to an ultra-fine denier viscose fiber and rayon fiber with simple and easy process, low energy consumption, low production cost, firm and smooth composite fiber and base cloth, soft hand feeling, delicate surface style, and transparent after being soaked in water. Composite cloth of Cell fiber and its preparation process. Background technique [0002] Viscose viscose fiber is a cellulose fiber obtained by extracting and reshaping fiber molecules from natural wood cellulose with "wood" as the raw material. The hygroscopicity of viscose fiber meets the physiological requirements of human skin. It is smooth, cool, breathable, Antistatic, anti-ultraviolet and other characteristics. It has the essence of cotton and the quality of silk. It is an authentic plant fiber, derived from nature and superior to nature. [0003] Viscose fiber is a cellulose fiber. It is made of natural fibers (wood fibers, cotton linters) as raw materials, t...

Problems solved by technology

[0008] The purpose of the present invention is to solve the problem that the composite cloth product prepared by the existing dry composite process is relatively rough, the composite of the fiber and the base cloth is not firm, and the overall surface style is not dense; the quality of the wet composite cloth such as smoothness, flatness, peeling, etc. Intensity, wear resistance, etc., along the width direction produce the phenomenon of poor consistency, and provide a simple and easy process, less energy consumption, low production cost, fiber and base fabric composite firm, smooth, soft hand feeling, and Laisai Combination of superfine viscose fiber and lyocell fiber composite cloth with the characteristics of water absorption and water retention, fine surface style and its preparation process
