Problems solved by technology

[0005] The disadvantages of the above-mentioned background technology: because the value ratio of regenerated viscose fiber is equal to or greater than 15%, and the length of regenerated viscose fiber is 4-20 mm, the non-woven fabric formed by spunlace with wood pulp fiber is due to water flushing. High dispersibility, but low entanglement strength, easy to break during use, resulting in inconvenient extraction of finished products and embarrassing use

Embodiment 1

[0013] Embodiment 1: with reference to attached figure 1 . A kind of fully degradable spunlace non-woven fabric for water flushing, which consists of 15%-85% by weight of regenerated cellulose fibers pretreated by pressing, milling and sorting, and 85%-15% of 4±0.5% wood pulp concentration discs The wood pulp fiber after milling is made into a fully degradable recycled non-woven fabric with a weight of 30g-120g / ㎡. Regenerated cellulose fiber refers to viscose fiber, tencel fiber, bamboo fiber, etc., and its structure is flat fiber structure, sawtooth fiber structure, round fiber structure, oval fiber structure and other irregular structures. The wet transverse breaking strength of the product is 350-750g / in, and the wet longitudinal breaking strength is 550-1200g / in.

[0014] The length of the regenerated cellulose fiber is 5.1-19.9mm, among the regenerated cellulose fibers, the fiber length is greater than or equal to 10.0mm and less than or equal to 19.9mm, accounting for ...

Embodiment 2

[0033] Embodiment 2: On the basis of embodiment 1, there are cuts on the regenerated cellulose fiber surface of flat fiber structure, sawtooth fiber structure, round fiber structure, ellipse fiber structure and other irregular structures, and its cut is to throw and cut forming .

Embodiment 3

[0034] Embodiment 3: On the basis of Example 1, 15% regenerated cellulose fibers and 85% wood pulp fibers are made into regenerated non-woven fabrics with a grammage of 30 g-120 g / ㎡ and the length of the wood pulp fibers is greater than 3.5 mm and 90-80% are less than or equal to 6.0mm, and 71-89% are regenerated cellulose fibers whose length is greater than 10.0mm and less than or equal to 19.9mm.

Abstract

The invention relates to water dispersing full-degradable spunlaced non-woven cloth which can meet the requirement for regenerative non-woven cloth entanglement performance strength and can be quickly dispersed and fully degraded under the action of water impact. The water dispersing full-degradable spunlaced non-woven cloth with the gram weight being 30-120 g / m<2> is prepared from, by weight, 15-85% of regenerative cellulose fibers and 85-15% of wood pulp fibers. The cloth has the advantages that the requirement of regenerative non-woven cloth entanglement performance strength can be met, the cloth can be quickly dispersed and fully degraded under the action of water impact, and environmental protection is facilitated.

Description

technical field [0001] The invention relates to a kind of fully degradable spunlace non-woven fabric which can not only meet the requirements of the entanglement strength of the recycled non-woven fabric, but also can be quickly dispersed and fully degraded under the action of water force. Degradable recycled non-woven fabric manufacturing field. Background technique [0002] Patent No. 3129192, name "water collapse non-woven fabric", fiber length 4-20mm regenerated viscose fiber weight 40-85% and pulp fiber weight 15-60% water collapse non-woven fabric, The non-woven fabric is treated with high-pressure water column to intertwine fibers, and it is a water-collapse non-woven fabric mainly characterized by a wet strength of 100-800gf / 25mm as tested by JIS P 8135. The weight of regenerated viscose fiber with a fiber length of 4-20mm is 40-85%, mixed with 15-60% of the weight of wood pulp fiber that has passed the Canadian standard freeness of 100-550ml CSF in the JIS P 8121 s...
