Polyvinyl alcohol non-woven fabric finishing agent-Textile finishing chemicals used in processing, giving textile more stiff, anti-wrinkle, anti-shrinking, or other specific properties.
Polyvinyl alcohol (PVA), as an environmentally friendly material, 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, polyvinyl alcohol (PVA) fibers formed by wet spinning and coagulation bath are directly used to produce polyvinyl alcohol non-woven fabrics without further acetal treatment, and have also experienced rapid development in recent years. Due to the water-soluble and environmentally friendly properties of polyvinyl alcohol non-woven fabrics, they have begun to replace non-woven fabrics made from plastic synthetic resins in many fields, such as shoe making, leather making, mattresses, mother and child comforters, decoration, chemical industry, printing, automotive, building materials, furniture, as well as clothing lining fabrics, medical and health disposable surgical gowns, masks, hats, bed sheets, hotel disposable tablecloths, beauty, sauna, and even today's fashionable gift bags, In the fields of boutique bags, shopping bags, advertising bags, etc. Especially in the field of disposable applications, it can replace traditional resin non-woven fabrics synthesized from plastics, making the product more environmentally friendly.
From the preparation technology and process of polyvinyl alcohol fibers, it can be seen that the polyvinyl alcohol solution is wet spun, and the resulting primary fibers solidify in an alkaline coagulation bath. After neutralization, water washing, multi-stage high magnification stretching, and heat treatment, they form fibers, resulting in polyvinyl alcohol fibers with excellent mechanical properties. Not only do they have high strength and modulus, but they also have excellent dispersibility. This fiber can produce various specifications of polyvinyl alcohol non-woven fabrics.
