Problems solved by technology

It cannot have excellent heat sealing properties like non-woven fabrics prepared by other commonly used plastic synthetic resins, so it is subject to certain restrictions in the application field, such as the second processing of non-woven fabrics: edge sealing, sealing, bag making, etc. etc., only traditional manual stitching can be performed instead of the process of automatic heat-sealing processing machinery
This leads to inefficiency in the product processing process of polyvinyl alcohol non-woven fabrics and high processing costs

Abstract

The invention discloses a preparation method and an application of a polyvinyl alcohol nonwoven fabric finishing agent. The finishing agent comprises, by weight, 10-20 parts of polyvinyl alcohol, 3-8parts of hydroxypropyl cellulose (HPC), 5-20 parts of amide modified polyol, 3-15 parts of alkyl glycosides, 5-10 parts of an inorganic filler, 1-5 parts of hydroxyethyl urea, 0.3-1.0 part of a penetrant, 0.3-1.0 part of imidazolidinyl urea, 0.1-0.3 part of p-hydroxybenzoate and 100 parts of water. The raw materials are mixed and heated to obtain the finishing agent. The finishing agent is suitable for the processes of padding finishing, sizing finishing, coating finishing and the like of a polyvinyl alcohol nonwoven fabric; and the polyvinyl alcohol nonwoven fabric is dipped in or coated withthe finishing agent, and then is dried, set and embossed. The nonwoven fabric finished with the finishing agent has improved heat-sealing performance and enhanced mechanical properties, so the hand feeling of the finished nonwoven fabric is also improved.

Description

technical field [0001] The invention relates to the field of post-treatment of non-woven fabrics, in particular to a preparation method and application of a polyvinyl alcohol non-woven fabric finishing agent. Background technique [0002] As an environmentally friendly material, polyvinyl alcohol (PVA) has been rapidly developed and applied in many fields in recent years. As a country with a large production capacity of vinylon, China has abundant sources of raw materials and application markets. In the pre-production process of vinylon, the polyvinyl alcohol (PVA) fiber formed by wet spinning coagulation bath is directly processed without acetal treatment. It is used to produce polyvinyl alcohol non-woven fabrics, and it has also developed rapidly in recent years. Due to the water-soluble and environmentally friendly properties of polyvinyl alcohol non-woven fabrics, it has begun to replace non-woven fabrics made of plastic synthetic resins in many fields, such as shoemaki...
