Problems solved by technology

Since it is composed of two layers of different materials instead of two kinds of fibers mixed together, the performance and feel of the front and back of the non-woven fabric will be quite different, which will cause inconvenience to the user; Consisting of a cellulose fiber web up to 17 mm, which will significantly reduce the flushability of the non-woven fabric, and does not have antistatic and antibacterial effects

Embodiment 1

[0061] A flushable and degradable mixed fiber water-punched nonwoven fabric and a preparation method thereof, comprising the following steps (all raw material ratios and processes refer to the contents shown in Table 3):

[0062]A) Raw material preparation, select 50-95% of natural cellulose fibers and 5-50% of man-made cellulose fibers by mass %, and the natural cellulose fibers are wood fibers, cotton fibers, bamboo fibers, grass fibers and plant straws Any one or more combinations in the fibers formed by cellulose, the man-made cellulose fibers are any one or more combinations in lyocell fiber, cupro fiber, viscose fiber and polylactic acid fiber, obtain raw material;

[0063] B) pulping, first pulverize the natural cellulose fibers in step A) with a hydropulper, and then successively refine them with a large taper refiner and a double-disc refiner to obtain a slurry, which is sent to the slurry for pulping. front pool reserve;

[0064] C) disperse fibers, decompose the m...

Abstract

The invention discloses a dispersible and degradable synthetic fiber spunlace nonwoven fabric and a preparation method thereof and belongs to the technical field of nonwoven products and preparation thereof. According to the preparation method, 50-95% of natural cellulose fibers and 5-50% of artificial cellulose fibers are selected; the natural cellulose fibers are smashed through a hydraulic smashing machine and then ground through a large-taper refiner and a double-disk grinder to obtain natural cellulose fiber paste; the artificial cellulose fibers are decomposed into artificial cellulose fiber suspension liquid for use; the natural cellulose fiber paste is sent into a primary flushing tank and a secondary flushing tank; the artificial cellulose fiber suspension liquid is sent into an inclined wire flow box to form a uniform fiber net; after water on the fiber net is absorbed, the fiber net is transferred into a pre-spunlace area on the lower portion of the flow box for pre-spunlace; the fiber net is punctured by high-pressure squirt cutters and rebounds, and fibers are entangled. Pollution to a human body and the environment is not caused; fracture resistance and tear resistance of the spunlace nonwoven fabric are improved; better anti-static performance and anti-microbial performance are achieved; water dispersibility is good; the fibers are distributed uniformly.

Description

technical field [0001] The invention belongs to the technical field of non-woven products and preparations thereof, in particular to a flushable and degradable mixed fiber hydrophobic nonwoven fabric, and also to a preparation method thereof. Background technique [0002] The mixed fiber spunlace non-woven fabric mentioned above refers to a kind of non-woven fabric that is obtained by mixing different fibers in a specific weight ratio and spunlacing by a spunlace machine belonging to the category of non-woven machinery, which is suitable for toilet or other cleaning and wiping. Non-woven fabrics for occasions. The above-mentioned flushable and degradable can be understood from its literal meaning: the desired flushability and degradable effects can be exhibited after being discarded, for example, thrown into a toilet bowl. [0003] As the flushable and degradable mixed fiber water-punched nonwoven fabric used in the above-mentioned occasions, in addition to the flushability...
