Description

Anti-pilling spunlaced composite non-woven fabric

Technical Field

The utility model relates to the technical field of non-woven fabrics, in particular to a fuzzing and pilling resistant spunlaced composite non-woven fabric.

Background

The non-woven fabric is a non-woven fabric, which is a novel fiber product with soft, breathable and planar structure, and is formed by directly using polymer slices, short fibers or filaments to form a net by air flow or machinery, then performing hydroentanglement, needling or hot rolling reinforcement, and finally performing after-treatment. When the surface of the article is wiped in the dry state of the non-woven fabric, the spun-laced non-woven fabric is formed by reinforcing short fibers through spun-laced water, so that the phenomena of fluff falling or pilling of floating fibers are unavoidable. Under the condition of high requirements of wiping, the hair is removed, so that short fiber scraps can fall on the surface of an article, and the subsequent use can be influenced. If the short fibers are fluffed and pilled, the wiping effect is affected, and in the wiping process, the fiber balls formed by the short fibers in a gathering way can fall off, so that the subsequent use of the article is affected. How to avoid the phenomenon that the non-woven fabric used as wiping does not fall off hair or become pilled when being used is a problem to be solved.
