Abstract

The invention discloses a production process of environment-friendly colored non-woven fabric, and relates to the technical field of non-woven fabric production. The preparation method comprises the following steps of: preparing raw materials, specifically, preparing 20-25 parts by weight of polypropylene, 2-3 parts by weight of bamboo fiber, 1-3 parts by weight of flax, 2-5 parts by weight of coconut fiber, 1-2 parts by weight of kapok fiber, 5-7 parts by weight of sisal hemp, 3-4 parts by weight of sawdust and 1.5-3 parts by weight of silk; performing scutching and mixing, bisecting the polypropylene, respectively mixing and scutching the bisected polypropylene and the other raw materials in the step 1; performing carding to form a screen, carding all the raw materials except the polypropylene into a base layer, then carding the bisected polypropyleneinto covering layers respectively; and adhering the two covering layers to the upper surface and the lower surface of the base layer respectively by using an adhesive to form a fiber screen. The soft degree of the outer layer of the non-woven fabric can be improved, and the comfort level can be improved conveniently; the toughness of the base layer in the non-woven fabric can be improved, and the overall bending strength and breaking strength of the non-woven fabric can be improved.

Description

technical field [0001] The invention relates to the technical field of production of non-woven fabrics, in particular to a production process of environmentally friendly colored non-woven fabrics. Background technique [0002] Non-woven fabric is composed of oriented or random fibers; it is called cloth because of its appearance and certain properties. Non-woven fabrics can be divided into seven categories according to different production processes: 1. Spunlace non-woven fabrics are sprayed with high-pressure fine water onto one or more layers of fiber webs to entangle the fibers with each other, thereby strengthening the fiber webs. And have a certain strength; 2. Heat-bonded non-woven fabric refers to adding fibrous or powdery hot-melt adhesive reinforcement materials to the fiber web, and the fiber web is then heated, melted and cooled to reinforce it into a cloth; 3. Pulp air-laid non-woven fabric Cloth can also be called dust-free paper, dry-laid papermaking non-woven...
