Dilute Dilute with warm water available, added to treatment bath Stir

Security No stimulation to skin, comply with environmental requirements. Storage and use of product should comply with chemical safety, and shall not swallow

【Features and Benefits】

The advantages of characteristics

Reaction type ultraviolet absorber and hydroxy groups, amine groups forming covalent bond, and having excellent durability of ultraviolet absorbing conversion performance, and ultraviolet blocking shielding effect

Do not affect shade, strength and moisture permeability of fluorescent brightener has little effect, will not change color of fabric. To guarantee fabric fresh and clean and comfortable to wear

High affinity with fiber product versatility applies to good padding, dipping, such as printing process can shield ultraviolet

The amount is small, role of durable and efficient with excellent durability, high washable and light stability, and results are not decreased after repeated laundry and strong ultraviolet radiation

【Application methods】

Padding fabric varieties and processing equipment, impregnated, cold pad printing process. UV-108 is fully bleached fabric may use alone, simultaneously with anionic dyes (reactive, direct, acid) can also dye or print, process conditions the same as with use of dye. The general dosage is 1 ~ 4% (o.w.f). The actual amount differs depends on purpose of different of processing technology and type of object to be processed, shape, organization, density and processing must test before use.

Cellulose fiber fabric to use as follows:

Padding process:

1. Formulation Process:

Anti UV finishing agent UV-108 10 ~ 40g/L

2. Process:

Padding UV protection solution (rolling rate 70 to 80%) →steam (saturated steam 100 ~ 105 ℃×60 ~ 90 seconds) or curing (130 ℃×2 ~ 3min) →hot water washing →cold water

3. Operation of material:

It should add trough first water and HTUV150, to ensure stability of padding solution to avoid UV-108 premature hydrolysis.

Second, impregnation process (with dye and bath):

1. Formulation Process:

Anti UV finishing agent UV-108 1 ~~ 4% (owf)

Bathratio 1:10 to 15

2. Process:

Per minute warming from room temperature to 80 ℃, 1 ~ 2 ℃, 30 ~~ 40min at 70 ~ 80 ℃, processing, hot water, and finally with cold water.


1. UV-108 and dye-bath, there may dye competing transfection problems, suggest in dark textiles after staining with UV-108.

2. UPF values ​​are varieties of fiber, fineness, cut surface and type of fabric, specifications, etc., and amount of ultraviolet absorber. The chosen fabric need to meet certain physical parameters in order to guarantee sufficient ultraviolet shielding effect. To minimize sunlight to penetrate fabric from exposure to skin, and porosity (the number of pores per unit area) should be less than 2%. It must test before use.
