Anti-UV Finishing Agent EMP UV-P Ultraviolet absorbent used for polyester textile
Uses:
EMP UV-P is the anti-UV finishing agent to treat polyester fabric to decrease transmission of ultraviolet ray into polyester fabric. EMP UV-P has excellent anti-UV effect and good wash-resistance.
Properties:
Appearance | Light yellow dispersion |
Composition | Benzotriazole derivatives |
pH value | 5.0-7.0 |
Desity(20ºC) | 1.02-1.05 |
Solubility | Can be diluted with cold water |
Application:
EMP UV-P can be used singly or in combination with disperse dyes. Application quantity: 1-3%(owf).
(1): High temperature dyeing process
Disperse dyes: X%; EMP UV-P: 1-3%;
Levelling agent: 0.5~1.5%; Acetic acid: pH=4.5-5;
Liquor ratio: 1:10 ~ 1:20
Heating up to 130ºC, and keeping at 130ºC for 30-60min.
Dyeing temperature and heating rate can be adjusted according to types of disperse dyes. If EMP UV-P is used singly, treating time can be shorted to 10 min. after heating to 130ºC.
(2): Thermosol dyeing process
Disperse dyes: X g/L; EMP UV-P: 25-50 g/L;
Migration inhibitor: 10-30 g/L;Penetrating agent: 0.5-2 g/L;
Pick-up rate: 60-80%; Dry:110-130ºC;
Cure: 190-210ºC
If EMP UV-P is used singly, cure conditions are:temperature:180ºC,time:30min.
(3):Padding process
EMP UV-P: 10-30g/L
Wash-resisting agent EMP FIX-ET: 10~30g/L
Padding EMP UV-P (pick-up rate:70%-80%)→ dry(90-110ºC)→ high-temperature heat-setting (170-190ºC×30s-90s or 120~130ºC×3~6min).
