Abstract

The invention discloses a finishing method for imparting negative ion health care functions to fabrics, comprising: taking 10 to 12 parts of water-based polyurethane in a container, adding 90 to 98 parts of deionized water and 7 to 9 parts of Toma in sequence Lin powder, 3-5 parts of opal powder, 5-6 parts of La 2 o 3 , 6-8 Ce 3 (PO 3 ) 4 and 2 to 3 parts of TiO 2 , stirring and reacting; adding 2-4 parts of dipropylene glycol, stirring for a certain period of time, ultrasonic treatment for 10-20 minutes; adding 1-2 parts of polyvinyl alcohol Z-200 and 1-2 parts of sodium polyacrylate, stirring for a certain period of time, and Ultrasonic treatment for 10-20 minutes to obtain negative ion finishing agent; soak the textile in the prepared finishing agent for 25 minutes, take it out and dry it in an oven at 15°C for 60 minutes, the finishing agent can be better adsorbed on the fabric, and can give the fabric a long-term The performance of releasing negative ions, and the number of negative oxygen ions in textiles reaches 6494 / cm 3 , can endow textiles with health care functions such as sterilization and enhancing human immunity.

Description

technical field [0001] The invention belongs to the field of post-finishing of clothing products, and in particular relates to a finishing method for endowing fabrics with negative ion health care functions. Background technique [0002] With the continuous development of the economy and society, the people are not only satisfied with the needs of textiles to cover their bodies and keep warm, but also require them to be multi-functional. Most of the free electrons generated by the ionization of air molecules under the action of high pressure or strong rays are obtained by oxygen. Therefore, negative air ions are often collectively referred to as "negative oxygen ions". Finishing agent, finishing textiles with negative oxygen ion finishing agent, makes textiles have negative ion health care function, which not only meets consumers' requirements for clothing functionalization, but also conforms to the trend of social development, so it is loved by people. [0003] Negative io...
