Stiffening agents are designed to improve the appearance of the fabric, increase the elasticity and fullness of the fabric, and give the material used for stiffening. Such substances shall be non yellowing and resistant to hot water washing. Commonly used are polyacrylate, polyvinyl acetate and their copolymers (perapret F50, K, VA, VW; stiffing agent 855), etc. Stiffening agent is applied to all kinds of fabrics. Its main function is to increase the stiffness of the fabric. The stiffening agent produced is not only of high stiffness, but also of strong durability. It is widely used in the later finishing of polyester, polyester cotton and other fabrics.

Stiffening agent, as the name suggests, is a kind of textile auxiliaries used to improve the handle and smoothness of the fabric, and make the fabric full, thick and flat friction resistant. At the same time, it can also improve the elasticity and tear strength of the fabric. It mainly includes: (1) the stiffening finishing of cellulose fiber and its blended fabric, most of which have direct contact with human body, such as clothing, bed sheet or bedspread, should choose aldehyde free stiffening agent; (2) the stiffening finishing of polyester, nylon and acrylic fiber fabrics, mainly for tents, bags, advertising cloth, curtains, etc.

Give the fabric a soft and full feel or a stiff feel. For example, soft finishing is a process to make up for the defects of stiff and rough handle of fabric and make it soft. Including mechanical softening finishing, chemical softening finishing and stiffening finishing. Mechanical softening finishing is mainly to use mechanical method to knead and bend the fabric for many times in tension state, so as to reduce the rigidity of the fabric and restore it to proper softness. Stiff finish is to make the fabric feel smooth, stiff, thick and plump, improve the strength and wear resistance, and also improve the drapery and appearance. Stiffening finishing is usually carried out in combination with sizing. Softener is added to the slurry to improve the comprehensive handle. Similarly, for simple softening finishing, stiffening agent is added to enhance the body bone. Application of Shanghai imported stiffening agent formaldehyde free fabric stiffening agent
