In the textile dyeing industry, the pursuit of fabrics with deeper and richer colors is an eternal theme. In recent years, a new type of additive called deepening silicone oil has emerged as a rising star in this field, contributing to the textile industry

Printing and dyeing enterprises have brought revolutionary solutions. This article will delve into the principles, advantages, and applications of deepening silicone oil in modern textile industry.

1. Definition and function of deepening silicone oil

Deepening silicone oil, scientifically known as polysiloxane deepening agent, is a synthetic inorganic polymer composed of silicon and oxygen atoms. It changes by forming a dense, uneven film on the surface of the fabric

The direction of light reflection reduces the amount of reflected light, thereby achieving a visual effect of increasing depth. Compared with traditional dyeing methods, darkening silicone oil can not only enhance the color depth of fabrics, but also save dye usage and reduce production costs.

2. Preparation method of deepening silicone oil

The preparation of deepening silicone oil is a delicate chemical process. Firstly, mix the organic silicon linear body with a specific silane coupling agent (such as γ - piperazinopropylmethoxysilane) in a certain proportion,

Then the reaction is carried out under heating conditions. Subsequently, an alkaline catalyst aqueous solution was added to continue the reaction, and finally neutralized by adding acid to produce a deep silica crude oil. This crude oil has been emulsified and stabilized

Processing, ultimately forming a deepening silicone oil product with hydrophilic, smooth, and deepening effects.

3. Advantages of deepening silicone oil

Environmental friendliness: New deepening silicone oils such as GRISEX? G-4798 does not contain harmful substances such as formaldehyde and meets environmental standards such as OEKO-TEX 100, reducing harm to the environment and human health.

Economy: By using darkening silicone oil, companies can reduce the amount of dye used while maintaining color depth, significantly reducing production costs.

Multifunctionality: Deepening silicone oil not only increases color depth, but also improves the texture of fabrics, providing a soft and fluffy touch.

Stability: High quality deepening silicone oil has good thermal stability and shear resistance, suitable for use in various dyeing and finishing equipment.

4. Application of Deepening Silicone Oil

Deepening silicone oil is widely used in the post-treatment of various fiber fabrics, including polyester, cotton, polyester cotton blends, etc. It can be used in various dyeing processes such as reactive dyes, dispersed dyes, and sulfide dyes.

Fabrics made with deepened silicone oil not only have deeper and more vibrant colors, but also have a softer and more comfortable feel.

Deepening silicone oil, as an innovative textile additive, not only enhances the aesthetics and added value of textiles, but also promotes the green development of the textile industry. With the continuous advancement of technology and market demand

Growth and deepening of silicone oil are expected to play a more important role in the future textile dyeing field.
