Description
Technical Field
The invention relates to a durable uvioresistant finishing process for light and thin real silk or silk-containing fabric, which has obvious uvioresistant effect after finishing light and thin real silk or silk-containing fabric and still has good uvioresistant performance after being washed for many times.
Background
Ultraviolet rays are electromagnetic waves with the wavelength range of 200-400 nm, human skin is very sensitive to the ultraviolet rays, and the human skin can be seriously damaged and even cause skin cancer after long-time sunlight irradiation without any protection. Therefore, the harm of ultraviolet radiation to human body is more and more paid attention.
The ultraviolet rays can be divided into three sections of UVC (200 nm-280 nm), UVB (280 nm-320 nm) and UVA (320 nm-400 nm) according to the wavelength, wherein the UVC is almost completely blocked by the atmosphere and hardly causes damage to human bodies. The ultraviolet rays which really penetrate through the barrier of the atmospheric ozone layer and reach the earth surface account for 1% of UVB and 99% of UVA. UVB is the main factor causing erythema in sunburn of the skin, and UVA has strong penetrating power and can penetrate the surface layer of the skin to directly reach the dermis, so that serious tissue damage can be caused, and skin cancer can be caused. Therefore, with the growing awareness of human health protection, the demand for various sunscreens and sun-blocking textiles is also rapidly increasing.
Currently, there are two main types of finishing agents used for textiles to resist ultraviolet radiation: one is ultraviolet absorbent, which is organic compound, such as cinnamic acid, salicylic acid, benzophenone, and diphenyl alkane. They generally absorb ultraviolet rays in the wavelength range of 290-320 nm, and have insufficient protection on ultraviolet rays in UVA wave bands; moreover, the skin-care product has certain irritation to the skin and is easy to cause skin allergy; the other is ultraviolet screening agent which is nano-sized or micro-sized TiO 2 、ZnO、SiO 2 、A1 2 O 3 Inorganic materials with good reflection, scattering or absorption effects on ultraviolet rays, such as Chinese patent with publication number CN102433602A, publication number of 2012 05 month 02 day, and publication number of 2012 month 2012, the method for producing durable ultraviolet-proof nylon-6 fiber uses nanometer ZnO and nanometer CeO 2 。

2) The padding mode is as follows: the concentration of the uvioresistant finishing agent in the finishing liquid is 30-50g/L, the concentration of the PU finishing agent is 20-40 g/L, and the light and thin real silk or silk-containing fabric passes through a mangle filled with the finishing liquid to ensure that the liquid carrying rate is 75-90%; the light and thin real silk or silk-containing fabric needs to be soaked and rolled for a plurality of times, so that the soaking and rolling are uniform and effective, and the finishing liquid fully permeates into the light and thin real silk or silk-containing fabric;
the impregnation method is specifically as follows: the concentration of the uvioresistant finishing agent in the finishing liquid is 10-20g/L, the concentration of the PU finishing agent is 5-10 g/L, and the light and thin real silk or silk-containing fabric is put into a rotating cage washing machine or a dyeing machine filled with the finishing liquid and is soaked for 10-20 minutes at the temperature of 30 ℃ so that the finishing liquid can be uniformly permeated into the light and thin real silk or silk-containing fabric;
3) Baking the dipped or padded light and thin real silk or silk-containing fabric by a setting machine at the baking temperature of 140-150 ℃ for 90-110 s to obtain a finished fabric;
4) Overfeeding the finished fabric on a pre-shrinking machine according to the proportion of 5-10 percent, and pre-shrinking the finished fabric;
the durable uvioresistant finishing process for the light and thin real silk or silk-containing fabric is applied to the gram weight of 50 to 100g/m 2 The real silk and the fabric containing the real silk are subjected to ultraviolet-resistant finishing; the uvioresistant finishing agent is one or two of transmissible 6160, UVR of Ludoufu and HTUV100 of Hertt uvioresistant finishing agent; the PU finishing agent is one or two of a tropina finishing agent BAYPRET NANO-PU, a transfer multifunctional finishing agent 6220 and an Ohio finishing agent RPU.
