Wet Rubbing Fastness Improving Agent Ht-818

[Main composition]
-- Special water-based polyurethane.

[General properties]
-- Ionicity: weakly cationic
-- pH: 3.5+0.5i 50g/Li

[Properties and fields of application]
-- Free of formaldehyde and APEO that belongs to environmental products and complies with EU OEKO-TEX Standard 100 requirements.
-- Use for fixing after cellulose fiber dyeing. Excellent wet rubbing fastness improving performance that can meet above Grade 3 by improving 1- 1.5 grades.
-- No influence on shade and light fastness.
-- It is obviously to improve the stability, such as resist to salt and hard water.

[Application]
Based on different kind and concentration of dyes, different kind and pattern of treated fabric, Dosage as below:
-- Dipping (washing only)

HT-818: 2-4% (O.W.F) (Adjustment base on color)
Bath ratio: 1: 10 a 20
Dyed fabrics (pH a 7) a Dip at 40a A 20 a 30 min a Dry

-- Padding:

HT-818: 30 a 50 g/L
Dyed fabrics (pH <= 7) a One dip & pad with water retention 80 a 85% a Dry

[Notice:]

-- Prepared solution should be used immediately.Please test before using.The above process is for reference only.
-- Only use alone, can not use for one bath with silicone oil, fixing agent and anionic agent.
-- The working liquid can achieve the best performance at 25-35a .
-- Please clean up the alkali (pH less than 7), salt and soaping agent of the fabric before using wet rubbing fastness improving agent 818.
-- Please clear away foaming or groove and change the working liquid because it will have a lot of foam when it use for a long time.
-- Make sure pH at 4.5-5 as possible.
-- The water use for liquid water should be less than 100ppm of the tap water.

[ Packing and storage ]
-- Packing: 125 kg/polyethylene drum
-- Storage: Keep it cool and dry, 6 months in sealed container at room temperature.
