Through an antistatic treatment, the effect of which can be temporary or permanent. EXOstat W is an agent with very good antistatic properties. In addition, it is also an effective softener and is used as a lubricant for raw materials in their natural state as well as those subjected to dyeing or printing processes. Other applications of surfactants in the textile production cycle Textile processing includes many stages. Different requirements arise in the production process. Due to the large-scale use of auxiliary agents, a large amount of foam is generated during wet dyeing and finishing of textiles, which reduces production capacity, makes work difficult, and has a negative impact on quality. There is a solution to this problem in the form of low foaming agents that prevent rapid and excessive foam growth. Antifoaming properties are often presented as one of the many properties of surfactants, along with wetting or emulsifying. An example is a condensed mixture of nonionic surfactants with a broad spectrum of properties: EXOdet W , which can be used as an effective low-foaming agent in the textile industry. Plus, it works well as a detergent. A specialized preparation based on cationic and nonionic surfactants Roksol AZR is good for similar applications.
Dedicated equipment, which must be clean and tidy, is an important part of the smooth running of textile processes. In the case of industrial washing machines, the perfect choice will be surfactants that play a key role in dissolving dirt, emulsifying fats and oils and removing them from the surface. The selection of appropriate washing agents affects the quality of future textile processing cycles and the CZ Leads maintenance CZ Leads of production machinery and equipment. It is therefore worth choosing recommended preparations, such as CZ Leads Rokanole IT , available in the PCC Group portfolio, which are intended for professional industrial cleaning . Groups of chemical compounds and their properties. Different groups of surfactants are used in the textile industry, depending on the desired effect. Ethoxylates are one of the most used groups of compounds . They have a wide spectrum of properties and applications while maintaining a high specificity of effects. Among the ethoxylates there are the following groups: Fatty alcohol ethoxylates that are an important factor in the textile industry. Its main function is emulsification. They are also used for cleaning, color matching, and as wetting agents. Fatty acid ethoxylates are used as emulsifiers, water softeners, wetting agents, and yarn coloring agents. Fatty amine ethoxylates are good oil emulsifiers and dye dispersants.
Types of plastics and their properties: duroplasts, thermoplasts and elastomers All plastics react to high temperatures in a certain way. When exposed to heat, some types of plastic shrink and deteriorate faster than others. Other types easily tolerate even very high temperatures and change their state of matter. Due to the reaction to heat, polymeric materials are classified into three groups: DUROPLASTS They are high quality thermosetting materials that do not melt and harden by heat treatment or by the action of a suitable hardener. Examples of duroplasts include: synthetic resins and polyacrylonitrile polymers. Duroplasts are used by laminate manufacturers and chemical, electrical, automotive, interior design and injection mold companies. THERMOPLASTS (also known as thermoplastics) are materials that change shape and become malleable under the influence of increasing temperature. Unlike duroplasts, thermoplasts can be reshaped many times and retain their shape when cooled. Examples of thermoplastics are: polyethylene and polystyrene. Thermoplastics are used, for example, in the production of packaging, films, toys, footwear or insulating materials. ELASTOMERS They are synthetic organic materials with the ability to stretch and return to their original shape. The elastomers category includes both synthetic and natural rubber, as well as other materials: polyurethane elastomers and silicones . The material is used on a large scale by manufacturers in the construction and finishing, medical, electrotechnical and automotive industries. Classification and use of plastics. Today, there are many applications for plastics and we are still discovering new ways to use them in everyday life.
