Finishing Chemicals
Textile finishing provides fabrics, yarns and fibers with special properties. This includes water and oil repellency, antistatic behaviour and flame retardancy but also soft handle, luster, wrinkle resistance and anti-slipping properties can be achieved.
Today, textiles need to meet demanding requirements which fibers, yarns, knitted and woven fabrics usually cannot fulfil. By optimizing textile-chemical or mechanical finishing after pretreatment, dyeing or printing, the goods can be provided with new properties and features.
For example, textile-chemical finishing includes the resin finishing of cellulosic fibers in order to reduce the creasing and shrinking tendency of fabrics. With this treatment, also called easy-care finishing, natural or regenerated cellulosic fibers are crosslinked by means of resins. These resin finished textiles are crease resistant and dimensionally stable. Furthermore, chemical finishing can provide textiles with antistatic, flame retardant, and oil or water repellent properties. Mechanical and thermal finishing include processes such as calendering, napping, sanforizing, shearing, emerizing, singeing or heat setting . Textile fabrics are often refined by both textile-chemical as well as by mechanical or thermal finishing processes.
The following is a selection of our textile auxiliaries for finishing:
1) Anticrease Agents
2) Antislip and Antisnag Agents, Lustering Agents
3) Water and Oil Repellents, Soil Release Products, Flame Retardants
Antistatic Agents
4) Optical Brighteners
Pretreatment Chemicals
A proper pretreatment of textiles is the basis for even and reproducible results in all subsequent finishing processes, such as dyeing and printing. When pretreating textiles, it is important to remove all interfering and accompanying substances from the fibers.
The area of pretreatment includes, among others, the following process steps:
- Washing and Scouring
- Desizing
- Bleaching
- Mercerising, alkalizing, and caustisizing
- Optical brightening
A high degree of whiteness on white fabrics can be achieved by applying the proper bleaching process and the addition of optical brighteners. Even dyeing and even effects in printing, coating, and finishing can be obtained only on suitably prepared, absorbent textiles, which have been cleaned from all interfering substances.
For the textile pretreatment of natural and synthetic fibers we offer the following product groups:
1) Defoamers
2) Washing Agents, Detergents
3) Complexing Agents
4) Sequestering Agents
5) Stabilizers
6) Wetting Agents, Deaerating Agents
7) Optical Brighteners
8) Enzymes
