Embodiment Construction

[0016] The process of the present invention will be further described below in conjunction with specific examples.

[0017] A non-woven fabric wet-laid process, using natural fibers and synthetic fibers as the main raw materials, opening the fiber raw materials placed in the water medium into single fibers, and at the same time mixing different fiber raw materials to make fiber suspension slurry, suspending The pulp is transported to the web forming mechanism, and the fibers are formed into a web in a wet state and then reinforced into a cloth. The specific steps are as follows:

[0018] (1) Raw material inspection: The raw material fibers are screened by a vibrating screen, and the vibration frequency of the vibrating screen is controlled at 200-600 times / min;

[0019] (2) Soaking: Soak the raw material fibers in deionized water, the water temperature is controlled at about 30°C, add a polyamide-based hydrophilic fiber treatment agent accounting for 0.5% to 5% of the deionize...

Abstract

Provided is a non-woven fabric wet process net forming technology. Natural fibers and synthetic fibers are taken as main raw materials, the fiber raw materials arranged in a water medium are opened into single fibers, different fiber raw materials are used for being mixed to form fiber suspension pulp, the suspension pulp is conveyed to a net forming mechanism, and a net is formed by the fibers in a wet state and then is strengthened into fabric. According to the non-woven fabric wet process net forming technology, the wet state opening and wet method net forming technologies are adopted, and the fibers in the manufactured fiber net are arranged disorderly and are almost isotropic; the fiber net is good in evenness, high in evenness degree, superior in filtering function, high in strength, modulus and elasticity, resistant to abrasion and good in temperature resistance and heat insulation effect and fire resistance, and has the functions of heat absorption, moisture absorption, deodorization, odor resistance, bacteria resistance and prevention, freshness preservation and the like and the function of electrical insulation.

Description

technical field [0001] The invention relates to the technical field of non-woven material production, in particular to a non-woven fabric wet-laid web-forming process. [0002] Background technique [0003] Nonwovens are also known as nonwovens, nonwovens, nonwovens, nonwovens or nonwovens. Nonwoven technology is a material processing technology that originates from textiles but surpasses textiles. Different nonwoven process technologies have their own corresponding process principles. But from a macro point of view, the basic principles of nonwoven technology are consistent, which can be described by its process, which can generally be divided into the following four processes: (1) fiber preparation; (2) web formation; (3) reinforcement; ( 4) Finishing. [0004] The current non-woven fabric production process has the following deficiencies: [0005] (1) Low product strength: due to short wood pulp fibers, spunlace non-woven fabrics use short fibers to go through the pr...
