The invention relates to a continuous processing technology for non-shrink treatment of chlorine-free wool tops and wool products. The continuous processing technology comprises the following steps: non-shrink treatment, washing, inactivation of protease, softening, dehydration, and drying. On the basis of the characteristic that wool fiber is protein fiber, the processing technology employs a high-efficiency integrated catalysis system composed of protease, a water-soluble aliphatic tri-substituted organic phosphine structured activator, a metal salt and a nonionic surfactant to efficiently and partially remove scales on the surface of the wool fiber so as to realize modification of the scales; thus, the felting performance of wool products is improved, dimensional stability of wool products is enhanced, and the requirement for machine washability is met. The continuous processing technology provided by the invention can replace chlorination anti-shrinkage methods in the prior art, avoids environmental pollution caused by the chlorination methods and is a clean treatment process according with environmental requirements. The continuous processing technology is small in usage amounts of reagents, low in cost, simple in process, low requirements on equipment and capable of realizing continuous operation and industrial production.

The invention relates to a method for preparing an antistatic anti-felting wool fabric with good dyeing property. The method comprise the following steps: pre-treating wool fabric with tris(2-carboxyethyl) phosphine (TCEP) to break disulfide bonds in wool fabric keratin to form sulphydryl with higher activity, and then grafting molecular chains containing acrylate in the presence of triethylamine through the thiol-ene click chemical reaction to obtain the wool fabric. The method disclosed by the invention not only has remarkable effect but also is safe and environment-friendly, has no harm to human bodies and environments, and is simple and effective as the groups of the wool are directly used as the active groups.
