Anti-ultraviolet additives for cotton
ClariantLei o ShanC with tag
Reactive ultraviolet absorbent for cellulose and nylon fabrics.
Operating as an ultraviolet absorbent, it reacts with cellulose fibers containing hydroxyl group and nylon fibers containing amino group. It produces the absorption effect of ultraviolet rays and has excellent fastness to sunshine and washing. It is suitable for dipping and rail dyeing.
The anti-ultraviolet finishing agent Leoshan C can be used in various cellulose and nylon fabrics (yarn, woven fabrics, knitted fabrics).
In the same bath with dyeing, the product may affect the dyeing properties of the fibers. Especially when dyeing with high concentration anionic dyes in the same bath, (active, direct and acidic), it may affect the color ratio. In fact, for dyed textiles (from medium to dark), it is recommended to use Leoshan C solution after dyeing.
The product absorbs ultraviolet radiation in the range of UV-B and has little or no effect on the fluorescent whitening agent. It does not change the color of the fabric.
Because it has covalent bonds with cellulose and nylon, Leoshan C liquid shows excellent durability. Ultraviolet absorption properties of fabric treated with Leo Shan C solution after repeated washing and consolation (ISO 105 E2 S, 9)5The temperature, 5 times, remained unchanged after chlorine washing (M S C37) and 200 hours of exposure (Xenon lamp). The colour fastness of dyed fabrics to sunshine and washing is not changed by the treatment of Leo Mountain C solution.

1. Application methods of nylon fabrics:
1.Immersion method
X% Leo Shan C Solution
40 - 60gram/ Salt (salt or sodium bicarbonate)
From room temperature to 98In order to maintain good absorption and leveling property, the temperature should be increased by 1.5-2 C per minute. Treat at 98 C for 15-30 minutes, then wash cold after hot washing.
2.Rolling and steaming process
Rolling bath Xg/Shenglioshan C liquid
20 grams /Salt (salt or sodium bicarbonate)
Rolling rate 60-80%, steaming for 5-7 minutes, 100-102 C (saturated steam), hot washing and cold washing
Two.Use methods of cellulose fibre fabrics:
1.Dip dyeing
5-10 minutes 30-40 minutes hot washing
25Temperature
Cold-washed salt X% Leoshan C(2+X%) soda ash
Bath ratio: Leo Mountain C has medium directness, so low bath ratio can obtain high fixation rate.
Salt 60-80gram/ Shengyuan Mineral Powder or Salt (Mineral Mineral Powder Can Have Better Fixation Rate)
Soda soda 2% more than Leo Mountain C solution (recommended several times)
Three.Continuous dyeing
Pad batch method
Rolling bath Xg/Shenglioshan C liquid
(5+0.25X) g/l soda ash
Rolling liquid rate is 60-80%, stacked at room temperature for 1-2 hours, hot washed and cold washed.
After mixing, Mount Leo C becomes active. Keep the temperature between 20 and 2 as far as possible.5Temperature, but it can also be slightly higher due to climate.
In order to ensure the stability of the dipping solution (avoid premature hydrolysis of the product), alkali and Leoshan C solution should be dissolved separately. After cooling the padding bath, the mixture of the two should be added to the dipping bath.
Hot melt method
Rolling bath Xg/Shenglioshan C liquid
(3.75+0). 125X) g/l baking soda or soda
YG/l urea
Baking soda makes the soaking solution stable. Adding 50-80 g/l urea in the soaking bath can improve the fixation rate, especially when the dosage of Leo Mountain C liquid is 30 g/l or higher, urea is recommended.
Rolling rate 60-80%, bake at 130 C for 2-3 minutes (1-2 minutes if first drying and then baking), hot wash and then cold wash.
