Cotton fabric anti-ultraviolet finishing application of ionic liquid metal complex and its finishing method and anti-ultraviolet cotton fabric

Abstract

The invention provides an ultraviolet resistant finishing application and ultraviolet resistant finishing method of a baffeta of an ionic liquid metal complex, and an ultraviolet resistant baffeta. The finishing method comprises the steps that immersing the baffeta into aqueous solution containing ferrite, then adding imidazolyl ionic liquid salt, and stirring at 20 to 80 DEG C for 2 to 10 hours; afterwards, adding alkali, reacting at 20 to 80 DEG C for 2 to 10 hours, and washing and drying the baffeta. According to the technical scheme, a full-wave band ultraviolet resistant barrier property is achieved, an ultraviolet resistant finishing technique is simple, in-situ generation reaction conditions are mild, and the realization is easy.

Description

technical field [0001] The invention relates to the application of fabric functional finishing of ionic liquid metal complexes, in particular to the new application of functional finishing of ionic liquid metal complexes to anti-ultraviolet cotton fabrics. Background technique [0002] The current fabric anti-ultraviolet finishing agents mainly contain two categories, one is anti-ultraviolet shielding agent, and the other is anti-ultraviolet absorbing agent. Anti-ultraviolet shielding agents mainly use reflection, refraction or scattering to reduce the transmittance of ultraviolet light to achieve the purpose of anti-ultraviolet, such as nano-inorganic materials such as zinc oxide, titanium dioxide, iron oxide, and silicon dioxide. When equivalent, it will scatter or reflect the ultraviolet rays of the corresponding wavelengths to achieve the anti-ultraviolet effect of the fabric. Therefore, if the anti-ultraviolet particles on the fabric have a single diameter, they can on...

AI Technical Summary

Problems solved by technology

Therefore, if the anti-ultraviolet particles on the fabric have a single diameter, they can only have a shielding effect on the corresponding one-band ultraviolet light, and cannot achieve full-band ultraviolet light shielding protection; Technical Problems of Low Washing Fastness of Finished Fabrics

The patent scheme of patent No. CN200410054186.5 discloses an anti-ultraviolet finishing solution. After finishing, titanium dioxide nanogel particles are formed on the surface of the fabric, which endows the fabric with excellent anti-ultraviolet performance, but the wash fastness is low; the patent number is: 200410053059.3 Titanium-containing nano-sol was prepared with tetrabutyl titanate as a precursor, and the cotton fabric was treated with anti-ultraviolet through rolling, drying and baking processes, which endowed the cotton fabric with anti-ultraviolet performance, but the hand feeling and mechanical strength of the finished fabric were affected to a certain extent
