Abstract

The invention relates to a hot-melt enhanced type flushable full-degradable non-woven material and a manufacturing method thereof. The hot-melt enhanced type flushable full-degradable non-woven material can achieve flushable and full-degradable effects with the percentage being 100% and has good strength. PVA hot-melt fiber accounts for 1%-5%, and end values are included; regenerated fiber accounts for 1%-50%, and end values are included; wood pulp accounts for 45%-98%, and end values are included. The hot-melt enhanced type flushable full-degradable non-woven material has the advantages that the hot-melt enhanced type flushable full-degradable non-woven material can satisfy the requirement for entanglement intensity of regenerated non-woven materials and can be flushed quickly under the action of water impact; after hot-melt PVA is added, 100% biodegradation can be achieved while product strength is enhanced by using bonding fiber; due to the design that the surface of regenerated cellulose fiber is napped, the junction surface of the surface of the regenerated non-woven material is increased, the purposes of solving the problem of small entanglement force and being high in entanglement intensity are achieved, and the hot-melt enhanced type flushable full-degradable non-woven material can be flushed quickly under the action of water impact.

Description

technical field

[0001] The invention relates to a heat-melt reinforced type flushable fully degradable non-woven material that can realize 100% flushable and fully degradable and has good strength and a production method, belonging to the field of non-woven material manufacturing. Background technique

[0002] Finland's Ahlstrom manufactures dispersible non-woven materials. In terms of the formulation of non-woven materials (1) PP / PE / : a mixture of PP or PE; structure: PP-coated core fiber on the outer layer of PE , PP has a high melting point and PE has a low melting point; its disadvantages: poor water absorption, significantly reduced dispersion, and full degradation cannot be achieved. Contents of the invention

[0003] Design purpose: To avoid the shortcomings in the background technology, to design a water flushing that can not only meet the requirements of the entanglement strength of recycled non-woven materials, but also quickly disperse and 100% fully degrade und...
