Abstract

The invention provides a processing technology and film modification method for a film-compounded non-woven fabric. The processing technology for the non-woven fabric comprises the following steps: S01, material preparation; S02, preparation of a base non-woven fabric; S03, preparation of a surface non-woven fabric; and S04, hot-press gluing. With the processing design of the nonwoven fabric in the invention, the structural strength of the nonwoven fabric produced by the invention can be improved, the flexibility and ductility of the nonwoven fabric can be enhanced, and the healthiness and functionality of the non-woven fabric are improved, so various needs of people on the non-woven fabric are satisfied.

Description

technical field [0001] The invention mainly relates to the technical field of composite non-woven fabrics, in particular to a processing technology of coated composite non-woven fabrics and a coating modification method. Background technique [0002] Non-woven fabrics have been widely used in many fields. There are also many types of non-woven fabrics, such as spunlace, acupuncture, thermal bonding and so on. Some non-woven fabrics can be used directly without post-finishing, and most non-woven fabrics can only be used after finishing or functional finishing, such as leather, filter materials, cleaning cloths, wallpapers, etc. There are many methods of non-woven fabric finishing, such as dipping, printing, coating, laminating, foam printing, coating foam and so on. There are also cooperative finishing, such as dipping and then printing, coating first and then printing, etc. In short, in the practice of non-woven fabric production, people have summarized and explored more ...
