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 spunlacing with wood pulp fiber is due to entanglement. The strength is high, and it cannot be dispersed instantly when water is flushed, causing the sewer pipe to be blocked, and due to the large amount of recycled viscose fiber, it not only leads to high manufacturing costs, but also poor environmental protection

Embodiment 1

[0012] Embodiment 1: with reference to attached figure 1 . A water flushing fully degradable recycled non-woven fabric, which is made of 1%-14% regenerated cellulose fiber and 99%-86% wood pulp fiber by weight, and has a weight of 30g-120g / ㎡ Fully degradable recycled non-woven fabric. 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.

[0013] 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 71-89%, and the fiber length is greater than or equal to 5.1mm and less than or equal to 9 . 9mm accounts for 11-29%.

[0014] Wood pulp fiber length 1.5-6.0mm, 99%-85% of the wood pulp fibers have a fiber length greater than or equal to 1.5mm and less than o...

Embodiment 2

[0015] 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

[0016] Example 3: On the basis of Example 1, 1% regenerated cellulose fiber and 99% wood pulp fiber are made into a water flushing dispersion fully degradable regenerated non-woven fabric with a gram weight of 30 g-120 g / ㎡ and wood pulp fiber The length of the regenerated cellulose fiber is greater than or equal to 10.0mm and less than or equal to 19.9mm, accounting for 90-80% of the length is greater than 3.5mm and less than or equal to 6.0mm, accounting for 71-89%.

Abstract

The invention relates to a water-dispersed full-degradable regenerated non-woven fabric capable of meeting the entanglement strength requirement and achieving quick dispersing and full degradation under the effect of water impact and consists of, by weight, 1%-14% of regenerated cellulose fiber and 99%-86% of wood pulp fiber which are manufactured into 30 g-120 g / <m> water-dispersed full-degradable regenerated non-woven fabric. The water-dispersed full-degradable regenerated non-woven fabric has the advantages that the entanglement strength requirement of the regenerated non-woven fabric can be met, quick dispersing and full degradation can be achieved under the effect of water impact, the using amount of the regenerated cellulose fiber is greatly reduced, the self energy of the regenerated cellulose fiber is greatly released under the cut effect to play the purpose of using few materials to obtain more energy, the manufacturing demand of the regenerated non-woven fabric is met, the using amount of the regenerated cellulose fiber is reduced, materials and energy balance design is achieved, raw material consumption is reduced, and environmental protection is facilitated.

Description

technical field [0001] The invention relates to a kind of fully degradable regenerated non-woven fabric which can not only meet the requirement of entanglement strength of recycled non-woven fabric, but also can be quickly dispersed and completely degraded under the action of water force, which belongs to fully degradable The field of recycled non-woven fabric manufacturing. 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-...
