Specifications

Alkaline agent is a cold pad batch dyeing agent for reactive dyes. It can efficient inhibit the aggregation of dyes .

Alkaline agent for CPB Reactive dyeing DA-GS711

Alkaline agent DA-GS711 is a cold pad batch dyeing agent for reactive dyes. It can efficient inhibit the aggregation of dyes with its solubilizing and dispersing property. Therefore the color spots and stains are reduced greatly. And because of its excellent penetrability, it can decrease the shade variation between inside and outside of the batching fabrics, also the selvedge and center variation. It is a good substitute for sodium silicate. For in traditional process, silicate will stain on rollers and then being transferred onto the fabrics form color spots. Property

• Appearance white particle
• pH value 11-12(1% solution)
• Solubility freely soluble in water

Characteristic

• Excellent dispersion, suspension effect, can effectively inhibit the aggregation of dyes, so reduce color spots and stains.
• Contribute to improve the stability of the working liquor.
• Increase color depth of the CPB dyed fabrics
• Good permeability, thus level dyeing and improving internal and external shade consistency.

Application Recommended dosage: 10-20g/L, pick-up: 70%~80%

Table 1. Dosage of Dyes and Chemicals
Materials Name	Dosage(g/L)
Dyes	≤10	10~40	≥40
Caustic Soda	2.8	4	6
DA-GS711	10	15	20

Note: the dosage in table 1 is with respect to the final liquor, so calculate again when separately dissolve the chemicals. Application method: first, dissolve the dyes and chemicals respectively and thoroughly, then the dye and alkali liquor are mixed at a convenient volume ratio (generally 4:1) by metering pump just before padding. For example, when the dosage of dye is 40g/L, caustic soda is 6g/L and the DA-GS710 is 20g/L, the volume ratio of dye and alkali is 4:1. Prepare 100L padding liquor, then need 80L dye liquor (dye 50g/L) and 20L alkali liquor (caustic soda 30g/L+DA-GS710 100g/L) Recommend ed process: preparation of padding liquor→ padding → uniformly roll up → covered with plastic sheet → batching for certain time( adjust the batch time according to the color depth) → warm washing → cold washing → soaping →warm washing → cold washing → drying. Notification:

1. The preparation of working liquor: must dissolve the dyes and DA-GS710 respectively, then mix the two liquor before padding in proportion.

2. Washing cycles: adjust the times of warm washing, cold washing and soaping according to the color depth
