Problems solved by technology

[0005] Its shortcomings: First, the multi-layer non-woven fabric has poor flushability; second, the material composition cannot be fully degraded, causing secondary pollution to the environment; third, because the raw materials have not been pretreated, the material itself The characteristics of the non-woven fabric are not released, so that the strength of the non-woven fabric formed in the necessary dry and wet state is weak

Embodiment 1

[0017] Embodiment 1: with reference to attached figure 1 and 2 . A flushable and fully degradable spunlaced nonwoven fabric, which is composed of 35-50% zigzag flat viscose fiber 9 and 65-50% wood pulp. The zigzag flat viscose fiber 9 is a deformed viscose fiber 10 after being spun and cut. The zigzag flat viscose fiber (deformed viscose fiber 10) has a length of 5-20 mm. Of the 35-50% zigzag flat viscose fibers (deformed viscose fibers 10), 70-80% have a fiber length greater than 10 mm and less than or equal to 20 mm, and 70-80% have a fiber length greater than or equal to 5 mm and less than or equal to 10 mm. 20-30%. The length of the wood pulp fiber is 1-5mm. Among the 65-50% wood pulp, 20-30% of the fiber length is greater than or equal to 1mm and less than or equal to 3mm, and 80-70% of the fiber length is greater than 3mm and less than or equal to 5mm. The technical indicators of the fully degradable spunlace non-woven fabric that can be washed away are as follows:...

Embodiment 1-1

[0020] Example 1-1: On the basis of Example 1, a fully degradable spunlaced nonwoven fabric that can be flushed is composed of 35% zigzag flat viscose fiber 9 and 65% wood pulp. The zigzag flat viscose fiber 9 is a deformed viscose fiber 10 after being cut off (see figure 1 mid-swing tangent). Among the 35-50% zigzag flat deformed viscose fibers, 70-80% have a fiber length greater than 10 mm and less than or equal to 20 mm, and 20-30% have a fiber length greater than or equal to 5 mm and less than or equal to 10 mm. Among the 65-50% wood pulp, 20% of the fiber length is greater than or equal to 1mm and less than or equal to 3mm, and 80% of the fiber length is greater than 3mm and less than or equal to 5mm.

Embodiment 1-2

[0021] Example 1-2: On the basis of Example 1, a fully degradable spunlaced nonwoven fabric that can be flushed is composed of 50% zigzag flat viscose fiber 9 and 50% wood pulp. The zigzag flat viscose fiber 9 is a deformed viscose fiber 10 after being spun and cut. Among the 35-50% zigzag flat deformed viscose fibers, 70-80% have a fiber length greater than 10 mm and less than or equal to 20 mm, and 20-30% have a fiber length greater than or equal to 5 mm and less than or equal to 10 mm. Among the 65-50% wood pulp, 30% of the fiber length is greater than or equal to 1mm and less than or equal to 3mm, and 70% of the fiber length is greater than 3mm and less than or equal to 5mm.

Abstract

The invention relates to a nonwoven fabric which can be quickly dispersed and fully degraded, in particular to the dispersible fully-degradable spunlace nonwoven fabric, a preparation method and a production line. The dispersible fully-degradable spunlace nonwoven fabric is composed of 35-50% of zigzag flat viscose and 65-50% of wood pulp. The dispersible fully-degradable spunlace nonwoven fabric has the advantages that the dispersibility is good; the viscose of the nonwoven fabric which is dispersed is fully degraded, so that secondary pollution to the environment is avoided; raw materials are pre-processed, so that the characteristics of the materials themselves are greatly released, and therefore the forming strength of the nonwoven fabric under the dry state and the wet state is good.

Description

technical field [0001] The invention relates to a flushable fully degradable spunlaced nonwoven fabric capable of fast flushing and complete degradation, a production method and a production line, and belongs to the field of flushable degradable nonwoven fabric manufacturing. Background technique [0002] US2013004552A1, entitled "Water Dispersible Nonwoven Fabric Material", provides a multi-layer nonwoven material, including continuous filaments of water-soluble or water-dispersible polymers with two outer layers as the inner water-absorbing layer. The continuous filaments of said nonwoven fabric material have a water content of less than about 10% by weight, and further comprise dry matter selected from the group consisting of household or personal care products, subject medical Substance and / or microcapsules of one or more such substances for sustained release, characterized in that the water-absorbing material comprises cellulose pulp fibers, characterized in that the no...
