Nature

appearance is light yellow liquid, pH value is neutral, cloud point 40~50 ℃, belongs to non-ionic surfactant. It has good stability, strong acid, strong alkali, sodium hypochlorite, hard water and heavy metal salts. Good water solubility. 5% of the aqueous solution was cloudy when heated above 45 °c. For all kinds of fiber without affinity, can be mixed with all kinds of surfactants. Non-toxic, non-flammable. Soluble in water, with excellent permeability, cloud point above does not affect the penetration.

Preparation Method

The C7 to C9 fatty alcohol was dehydrated in vacuo under base catalysis, and then reacted by adding ethylene oxide.

Introduction

Sodium alkyl sulfate surfactant.

Use

It is mainly used as wetting agent and penetrating agent in textile printing and dyeing industry, and can be used in various processes of fabric bleaching, scouring, dyeing and finishing, such as sizing, Desizing (especially biological enzyme Desizing), scouring, bleaching, carbonization, chlorination, dyeing, Resin finishing and other processes. With the help of the osmotic agent JFC {penetration, the dosage is 1-4g/L. Has a strong ability to wash hair. The fiber is soft, whether in acid, neutral or alkaline can be used, the general amount of wool washing is 1% to 2% of the gross weight. In biological enzyme Desizing (starch slurry), add penetrant JFC to accelerate Desizing, the general dosage is 0. 1%~ 0.5%, wool carbonization liquid can add penetrant JFC, so as to shorten the carbonization time, reduce the amount of acid, improve the carbonization effect, the amount of 0.5~2G/L. The scouring effect can be improved by adding penetrant jfc2-5 g/L to the scouring of acetate fiber and other synthetic fibers.
