Product Description

RUISOFT 8063M is a linear block silicone copolymer, with quat, polyether functional groups and other traditional chemical entities. RUISOFT 8063M is virtually 100% active, delivers a smooth and silky softness to cotton knits and all kinds of cellulosic and their blends. After the treatment of RUISOFT 8063M, the fabric still maintain their original hand characteristics and quick water absorption.

Features and Advantages

● Provides smooth, silk, rich and in-depth softness with dry/cool feel on virtually all types of cellulosic fabrics

● Help preserve natural feel on cotton knits and sheets

● Due to excellent exhaustibility and affinity with cellulosic fibers, helps provide unusually softness effect with low use levels

● Minimal impact on the hydrophilic nature of cotton and cotton blends; typically provides quick absorption

● High cost performance because of 100% active content

● Easily emulsified by using simple mixing devices and procedure and typically generates emulsions that possess high shear and pH stability

● Good chemical stability, can resist high temperature, salt, pH and high shearing

● Easy to emulsify

● Lower dosage

● Virtually no yellowing of white or light color fabrics

RUISOFT 8063M can be used for all kinds of cellulose fabrics, including regenerated cellulosic and cellulosic blends. RUISOFT 8063M should be emulsified before applying in textile finish process. It is easier to be emulsified than other traditional silicone oil for textile softener. Normal equipment and emulsifier can meet the requirement.

The emulsion of RUISOFT 8063M is extremely stable in a wide pH range, high temperature or high concentrations of salts. As a result, RUISOFT 8063M can be used in most types of finishing equipment, such as exhaustion, high-speed padding, jet finishing, kiss-roll, spraying and others.

Because of its cationic structure, RUISOFT 8063M has limited compatibility with anionic auxiliaries. Compatibility tests should be carried out before it is used together with other chemicals.
