Abstract

The invention discloses an Australian wool top complete-easy-care finishing technique which comprises the following steps: 1) water washing; 2) water-based organic silicon polyurethane padding treatment: the water-based organic silicon polyurethane care solution comprises the following components in percentage by mass: 65-75% of water-based organic silicon polyurethane, 2-5% of anti-shrinking agent, 1-4% of softener, 2-4% of film forming aid and 20-25% of water; 3) predrying; and 4) drying. The technique is simple, controllable, safe and environment-friendly. The Australian wool top is subjected to padding treatment by using the water-based organic silicon polyurethane care solution, and dried to form a durable water-based organic silicon polyurethane film on the Australian wool top surface, thereby wrapping the Australian wool top, and enhancing the elasticity and felting resistance of the Australian wool top; and thus, the Australian wool top can achieve the complete easy care effect.

Description

technical field [0001] The invention relates to the technical field of processing Australian wool tops, in particular to a completely easy-care finishing process for Australian wool tops. Background technique [0002] The surface of the wool fiber has a scale layer with a special structure. Under the friction of the external force, the scale layer moves in a directional way and the phenomenon of felting occurs. Therefore, the wool fiber strip must be finished and processed to meet the machine washable standard stipulated by the International Wool Bureau. , At the same time, the post-finishing process can improve the hand comfort of wool fiber strips. [0003] For a long time, most enterprises have used chlorine-containing oxidants to finish the wool fiber strips in order to achieve a good anti-felting effect. However, during the finishing process, chlorine-containing oxidants will produce a large amount of AOX (adsorbable organic halides), which seriously pollute the enviro...
