Organic silicon modified fabric softener is an important textile additive, and its raw materials mainly include polydimethylsiloxane (PDMS) and its modified derivatives.
The following is a detailed explanation of the raw materials for organic silicon modified fabric softeners:
1. Basic raw materials
Polydimethylsiloxane (PDMS): As the main component of organic silicon modified fabric softeners, PDMS is widely used in the textile industry due to its excellent softness, smoothness, and chemical stability. It can form an ordered arrangement through cross-linking reaction with fibers, effectively improving the softness and flexibility of fabrics.
2. Modified raw materials
In order to endow fabrics with more functionality and improve their performance, PDMS is usually modified. Common modified raw materials include:
Polyether: Through polyether modification, hydrophilic polyether segments can be introduced, greatly enhancing the hydrophilicity of silicone softeners. This modified softener not only gives the fabric better softness and smoothness, but also enhances its anti staining and anti-static properties.
Amino: Amino modified fabric softeners play an important role in fabric softening finishing, with a wide range of applications and large usage. The introduction of amino groups enables the softener to interact with the hydroxyl and carboxyl groups of fibers, giving the fabric better softness, smoothness, and fullness, while enhancing the fabric's drape, wrinkle recovery, and sewing properties.
Epoxy based: Epoxy based modified fabric softeners are favored for their non yellowing properties. It can maintain the softness of the fabric while avoiding yellowing during the finishing process.
Carboxyl group: Carboxyl group modified fabric softeners can give finished fabrics a unique silky feel and are widely used in the processing and finishing of synthetic fibers, silk, and linen fabrics.
3. Other auxiliary materials
In the process of preparing organic silicon modified fabric softeners, auxiliary materials such as emulsifiers, catalysts, stabilizers, etc. may also be required. The addition of these raw materials helps to improve the dispersibility, stability, and processing performance of the softener, thereby ensuring the quality and effectiveness of the final product.
In summary, the raw materials for organic silicon modified fabric softeners mainly include polydimethylsiloxane and its modified derivatives (such as polyether, amino, epoxy, carboxyl, etc.), as well as auxiliary materials such as emulsifiers, catalysts, stabilizers, etc. The synergistic effect of these raw materials makes organosilicon modified fabric softeners play an increasingly important role in the textile industry.
