In the solar spectrum, ultraviolet rays account for about 6%. Ultraviolet rays not only fade and embrittle textiles, but also produce melanin and stains on human skin. What's more serious is that it can also induce cancer. It is necessary to protect it. The principle of ultraviolet protection is to use ultraviolet absorbers and reflectors to treat fibers or fabrics. The ultraviolet absorbers absorb high-energy ultraviolet rays and convert them to low-energy, turning them into low-energy heat or short-wavelength electromagnetic waves. To eliminate the harm of ultraviolet rays to the human body and fabrics, ultraviolet reflectors can increase the reflection and scattering of ultraviolet rays by fabrics, and prevent penetration of fabrics.
 
Product traits and technical indicators
 
anti-ultraviolet finishing agent SCJ-965 contains ultraviolet absorber and reflector. SCJ-965 is suitable for the anti-ultraviolet finishing of cotton, silk, linen, polyester cotton and other fabrics. The treated fabric has good absorption of ultraviolet rays in the 180-400nm band, especially UV-A and UV-B. SCJ-965 finishing The UPF value of T/C 45X45 110X76 plain cloth is still 50+ after 40 times of washing.
 
Anti-ultraviolet finishing agent SCJ-965 is non-toxic, non-flammable, non-explosive, safe to the human body, non-irritating to the skin, no allergic reaction, and does not affect the color and strength of the fabric. The appearance of SCJ-965 is milky white liquid, the solid content is 35%, the PH value is about 7, the ionicity is non-ionic, and it is miscible with water.
  Instructions for use
 
1. Process formula: (Take 75% rolling rate as an example)
 
Anti-ultraviolet finishing agent SCJ-965 80-120 g/L
 
Silicone softener SCG 10-25 g/L
2. Chemical operation: (take the preparation of 500 liters of solution as an example)
 
First add about 300 liters of water into the chemical tank, stir and add SCJ-965, then add SCG, mix well, finally add water to 500 liters, and continue to stir.
 

3. Process flow: bleached and dyed fabric —> padding anti-ultraviolet solution —> drying (80-110℃) —> tentering (160-170℃, 30 seconds).
4. Points to note:
 
1) After padding the anti-ultraviolet solution, attention should be paid to prevent migration. It is best to use infrared rays or hot air to pre-dry, and then dry in a drying cylinder.
 
2) The processing method of knitwear, etc. can be: dipping -> dehydration -> drying (80-110 ℃ 6-10 minutes). (The solution thrown out by centrifugal dehydration can be reused).
Packaging and storage: 25Kg plastic bucket packaging. Stored in a cool warehouse above 0℃, the storage stability period is one year. Product price: anti-ultraviolet finishing agent SCJ-965 95 yuan/Kg
