Antibacterial functional finishing of nano-printing and dyeing technology
In recent years, the application of nanomaterials and nanotechnology in the field of fabrics has good technical reserves, and specific products have been continuously developed in production. The content here not only includes the preparation of nanomaterials, functional application methods on fiber and fabric products, and the formation and manipulation of nanostructures, but also must have reliable industrial manufacturing prospects. The focus of industrialization is mainly on the feasibility of mass production processes and equipment, as well as appropriate cost requirements.
In printing and dyeing, antibacterial fabrics have to go through multiple processes such as spinning, weaving, bleaching, dyeing, and finishing. Therefore, in addition to the fact that the fiber raw materials must have antibacterial properties as the basis, the fabric production and finishing process , especially the selection of process conditions such as bleaching, dyeing, and finishing chemicals, temperature, and time, must be carefully selected based on the type and nature of the bacteriostatic agent.
At present, antibacterial finishing fabrics are mainly made of natural fiber products. In the past, they were mainly manufactured using quaternary ammonium salt type silicone antibacterial finishing technology. Antibacterial finishing using nanotechnology is a newly developed antibacterial finishing technology in recent years, which is applied to inorganic nanobacteriostatic agents and organic and inorganic combined bacteriostatic agents.
In actual production, when the proportion of antibacterial fibers in the blended chemical fiber fabric yarn is relatively high (such as more than 50%), the blended chemical fiber fabric yarn and its fabrics still have good antibacterial properties. . Therefore, the dual technology of antibacterial fiber and antibacterial finishing can be used to obtain antibacterial blended chemical fiber fabrics with excellent performance.
Currently, antibacterial finishing fabrics have been used in knitted underwear and bedding. Antibacterial fiber and its blended chemical fiber fabrics can also be used in shirts, train bedding, nurse uniforms, taxi seat covers, etc.
