anti-ultraviolet finishing agent HTUV100：Anti-UV finishing agent HTUV100 is manufactured by Herst International Group, which can be used for efficient and durable UV finishing of cotton, silk, wool, polyester, nylon and blended fabrics and to improve the fastness of some dyes. Clothing, beachwear, bath suits, casual clothes (T-shirts, shirts, hats, etc.), professional wear and tents, umbrellas, curtains and other UV shielding performance. The basic traits of HTUV100: Component: Triazepine Derivatives High Efficiency UV Absorbent Materials Appearance: light yellow liquid：Ionicity: Nonionic：PH: about 7：Solubility: miscible with water： Stability: in hard water, in the pH of 5 ~ 8 acid, alkali solution stability, easy to use Compatibility:
Safe use of anionic or cationic products The HTUV100 has the following characteristics:①, the polymer of the UV absorber, with excellent durability of the UV absorption and UV blocking shielding effect, the 180 ~ 400 nm band of ultraviolet absorption has a good absorption, reflection and scattering.
②, the amount of small, efficient and lasting effect, in the appropriate structure of the textile has a high UPF value.
③, and fiber affinity, thermal stability, suitable for a variety of processes, to the greatest degree of shielding UV
④, reactive products can be linked with the fiber, a very high resistance to washing and light stability, repeated washing and strong ultraviolet radiation effects are not decreased.
⑤, product versatility is good, easy to use. Applicable to finishing, coating, printing, spraying and high temperature suction method, padding process.
Property anti-ultraviolet finishing process screening：①, process recipe：
The test showed that the following formulation was used for the T40 / C60 45 * 45 110 * 76 fabric to achieve good UV protection.
Prescription (g / L): anti - UV finishing agent HTUV100 30
Crosslinking agent AF6900 30
②, process flow(90 ~ 80%) → drying (90 ~ 110 ℃) → high temperature tenter (170 ~ 190 ℃, 30 s). test results and discussion：
①, anti-ultraviolet performance test；
② Determination of formaldehyde content：
The use of GB / T2912.1 textile formaldehyde determination, anti-ultraviolet finishing agent HTUV100 finishing fabric formaldehyde content is 10 mg / kg, in full compliance with GBl8401 - 2001 "textile formaldehyde content limit" national mandatory standards.
③, irritating to the skin：
10% of the Japanese ear standard experimental rabbits with both sides of the spine were cut off, the 4% UV finishing agent HTUV100 application solution coated on the gauze, applied to the right side of the exposed skin.
24 h after the observation of the application of skin parts, no erythema and edema and other symptoms, according to the skin irritation strength grading standards, the anti-ultraviolet finishing agent application of the skin is a non-stimulating substance.acute oral toxicity：4% anti-ultraviolet finishing agent HTUV100 dose of l0000 mg / kg, the daily observation of animal poisoning performance, 10% of the anti-ultraviolet finishing agent HTUV100 application 40 pairs of fasting 16 h Kunming standard mice one-time oral administration, Day end of the experiment, each group of experimental animals throughout the course of the experiment, without any poisoning performance, diet and exercise were normal, no animal died. According to the acute toxicity classification standard, the 4% anti-ultraviolet finishing agent application liquid is the actual non-toxic substances.
