Ultraviolet rays in the solar spectrum not only fade and embrittle textiles, but also cause sunburn and aging of human skin, producing melanin and stains, and even more serious, it can induce cancer and endanger human health. The protection principle of AU-120 anti-ultraviolet fabric is that AU-120 absorbs high-energy ultraviolet rays, transforms it into low-energy through the jump of molecular energy level, and turns it into low-energy heat or electromagnetic waves with shorter wavelengths, thereby reducing the intensity of sunlight. , To eliminate the harm of ultraviolet rays to the human body and fabrics; at the same time, AU-120 can also increase the reflection and scattering of ultraviolet rays from the fabric, and prevent ultraviolet rays from penetrating the fabric.
 
Beijing Jiershuang High-Tech Company is a manufacturer of anti-ultraviolet finishing agent. The anti-ultraviolet AU-100 anti-ultraviolet finishing agent has been put on the market in large quantities for 20 years. JLSUN® anti-ultraviolet finishing fabric meets the Chinese standard "GB/T18830-2009 Evaluation of Textile Anti-ultraviolet Performance", Australian/New Zealand standard AS/NZS 4399:1996, European Union standard EN13758-1:2001 and EN13758-2:2003, American AATCC183 -2004, ASTMD 6544 and ASTMD 6603, British Standards BS8466-2006, BS7914-1998 and BS7949-1999, International Certification Association Standard UV Standard 801 and other domestic and foreign standards. Jiershuang laboratory provides customers with free testing of the anti-ultraviolet effect of fabric.
 
Product performance technical indicators
 
Anti-ultraviolet finishing agent AU-120 is suitable for the anti-ultraviolet finishing of cotton, linen, silk, wool, nylon and their blended fabrics, especially suitable for knitted fabric dipping method. The product can improve the anti-ultraviolet properties of fabrics, eliminate the harm of ultraviolet rays to the human body and fabrics, and can improve the light fastness of some dyed fabrics.
 
AU-120 is a new generation of environmentally friendly anti-ultraviolet finishing agent, which does not contain harmful substances such as formaldehyde and heavy metal ions, and meets environmental protection requirements. It has a strong absorption effect on ultraviolet rays with a wavelength of 180-400nm, and converts it into light energy and heat energy to release. AU-120 mainly contains ultraviolet absorbers and has reactive groups, which can bond with the hydroxyl and amine groups on the fiber, and has excellent washing resistance. The treated ordinary fabric has a good absorption, conversion, reflection and scattering effect on the ultraviolet (especially UV-A and UV-B) in the 180-400nm band. Tests by authoritative organizations at home and abroad have proved: JLSUN® anti-ultraviolet JC40×40 110/ The UPF value of 90-color plain cloth is as high as 50+, and the UPF value is still 40+ after 40 washings, and it has no adverse effect on the color and feel of the fabric.
 
Appearance of anti-ultraviolet finishing agent AU-120: milky white viscous liquid, pH value: 7-8, ionicity: anion, water solubility: miscible with water in any ratio.
 
Usage and dosage
 
AU-120 can be used to finish fabrics by padding, dipping, coating or spraying. The dosage is usually 2-3% (o.w.f.). The specific dosage and usage depends on the type, specification and purpose of the fabric. UV-120 is particularly suitable for the same-bath dipping process of knitted fabrics anti-ultraviolet finishing and reactive dye dyeing.
 
Dyeing and anti-ultraviolet finishing in the same bath: the amount of anti-ultraviolet finishing agent AU-120 is 1-4% (o.w.f). AU-120 can be added to the dyeing vat together with reactive dyes or direct dyes and used in accordance with the corresponding dyeing process.
Soft, anti-ultraviolet finishing in the same bath: bleached and dyed fabric → padding with anti-ultraviolet solution (AU-120 20-40 g/L, appropriate amount of softener) → drying (80-110℃, 3-5min) → tentering ( 150-170℃, 30s).

Chemical material operation: first add warm water (40-60℃) into chemical material tank, then add AU-120, stir, and finally add anionic or non-ionic softener, and stir evenly.
 
anti-ultraviolet finishing agent AU-120 can also be used to produce anti-ultraviolet viscose fiber, adding 1-3% AU-120 to the viscose liquid.

Package and storage: 25Kg plastic bucket, stored in a cool warehouse above 0℃, storage period is one year.
