Problems solved by technology

[0005] However, in the production process, there are still certain technical problems to be overcome. For example, 1. How to reduce the friction and entanglement between the regenerated fibers and reduce the static electricity of the fibers during the pretreatment of the leftover fibers; Fiber cohesion of regenerated fibers in the subsequent processing; 3. How to reduce the linters and dust of regenerated fibers as much as possible, and reduce the neps generated during the opening and regeneration process; 4. How to avoid or reduce the shedding generated during use 5. Since the regenerated fiber has a large difference in fiber length, the average length is short (between 2m

Abstract

The invention discloses a 100% regenerated fiber spunlace non-woven fabric which uses recycled spunlace non-woven fabric leftover material as a raw material. The production method of the 100% regenerated fiber spunlace non-woven fabric includes raw material pretreatment, raw material retreatment, opening, mixing and impurity removing, carding and netting, spunlace and primary drying, and drying and product finishing. Opening adopts a non-holding manner; a carding machine is additionally provided with a fiber cohesion roller and uses air flow to assist stripping; spunlace water is recycled water which is circularly supplied by a multilevel water circulation processing system, and filtering manners including an air flotation filtering manner, a sand filtering manner, a metal filtering manner and a bag refined filtering manner are used to filter out impurities in water; a novel safe emulsion is used to treat a spunlace fiber net by adoption of an impregnation method or a foam method; the cohesion and the combination among the regenerated fiber can be effectively improved, and the physical performance of the spunlace non-woven fabric finished product is improved; hair falling and bit falling can be avoid during use of the spunlace non-woven fabric, the service life of the spunlace non-woven fabric is prolonged, or the use times of the spunlace non-woven fabric are increased; and the spunlace non-woven fabric has excellent water absorbing performance, is durable and laundering-resistant, and can be used with most of cationic type antibacterial agents.

Description

Technical field [0001] The invention relates to the field of spunlace non-woven fabric regeneration production, in particular to a spunlace non-woven fabric using 100% recycled fiber as raw material. Background technique [0002] Spunlace non-woven fabrics are sprayed with high-pressure fine water jets onto one or more layers of fiber webs to entangle the fibers, so that the webs can be reinforced and have a certain strength. The fabric made is the spunlace non-woven fabric . Its fiber raw materials have a wide range of sources, such as polyester, nylon, polypropylene, viscose fiber, chitin fiber, superfine fiber, tencel, silk, bamboo fiber, wood pulp fiber, seaweed fiber, etc. [0003] Traditional spunlace nonwovens (commonly known as: spunlace nonwovens) use short fibers such as polyester, viscose or cotton as the main raw materials, and the fiber length is between 30mm-40mm, which requires high fiber length. [0004] Through more than 10 years of research and exploration, throug...
