Exploring How Non-woven Fabrics Have UV Protection

Method for producing anti-ultraviolet nonwoven fabric

The UV-resistant nonwoven fabric is mainly produced by the following two methods.

1. Anti-UV fiber pile production anti-UV non-woven fabric(Anti-UV Non-woven Fabric Factory)

In general, a metal oxide such as titanium oxide or zinc oxide can be added to the spinning solution to produce an ultraviolet shielding fiber. Since the organic anti-UV agent decomposes when subjected to a large dose and a long-term ultraviolet irradiation, the inorganic ultraviolet shielding agent is applied more. In the polymer, a mother liquor of 5% concentration of ultrafine titanium dioxide particles is used to obtain a fabric having a long-lasting ultraviolet protection ability.

2. Anti-UV finishing of non-woven fabrics(UV Resistant Nonwoven Vendor) Anti-UV finishing of non-woven fabrics, the most important thing is to use anti-UV shielding agent. It uses high refractive index metal oxides to make fine particles and ultrafine particles, and then selects a suitable dispersant and other additives to form an anti-UV finishing agent to finish the nonwoven fabric. For example, a nonwoven cover material requires a coating treatment, and the function and life of the coated nonwoven depends on the extent to which it is blocked by ultraviolet light. Common coating materials are polyvinyl chloride (PVC), polyurethane (PU), polyacrylic acid, and polytetrafluoroethylene (PTFE). Anti-ultraviolet finishing of the agricultural non-woven(Biodegradable Nonwoven Fabric On Sales) insulation curtain can ensure the transmittance of sunlight during the day, and at the same time ensure that the curtain is not aging by the radiation of sunlight.
