Abstract

The invention discloses a treatment method for antibacterial and anti-ultraviolet cotton fabrics. The treatment method comprises the following steps: step 1, soaking the cotton fabrics with a nonionic surfactant; step 2, modifying the cotton fabrics with chitosan quaternary ammonium salt; step 3, dipping the cotton fabrics with antibacterial finishing liquid prepared by mixing 5-15 parts of a natural antibacterial agent composed of extracts of grape seeds, persimmon leaves, ginkgo leaves and licorice roots, 0.3-1 part of polyoxyethylene-40 hydrogenated castor oil and 1000 parts of water; step 4, soaking the cotton fabrics in a mixed aqueous solution containing 0.001-0.005mol/L of silver nitrate or silver sulfate or silver acetate and 1-3 g/L of soluble starch or hydroxyethyl cellulose to prepare the nano-silver attached antibacterial cotton fabrics. The prepared cotton fabrics not only have good antibacterial performance and anti-ultraviolet performance, but also have performance of resisting oxidation and scavenging free radicals, and have improved anti-wrinkle performance and good washing durability.

Description

technical field [0001] The invention relates to the finishing technology of textiles, in particular to an antibacterial and anti-ultraviolet treatment method for cotton fabrics. Background technique [0002] Cotton fabric has good moisture absorption and breathability properties, good warmth retention, comfortable and soft, and is very suitable for use as clothing fabrics. [0003] However, cotton fabric itself does not have special functions such as anti-ultraviolet and antibacterial. In addition, cotton fabrics have the problem of being easy to wrinkle. [0004] Cotton fabric is a natural fiber with good hygroscopicity, which is easy to become a medium for microbial proliferation. Endowing cotton fabric with antibacterial function and preventing the spread and proliferation of pathogenic microorganisms on the fiber is very important for protecting health and improving fabric performance. [0005] Ultraviolet radiation can cause acute and chronic reactions and damage, su...
