The textile defoamer is mainly designed for the foaming characteristics of textile size and printing and dyeing process (below 80 ℃) in the textile industry. The defoamer has good dilution stability. The 30% defoamer solution can meet the requirements of six months of storage without layering. It is resistant to acid and alkali flooding and can be made into weak anionic lotion according to customer requirements. Widely used in the production of ordinary textile pulp, high-speed textile pulp, medium temperature printing and dyeing, adhesives, cutting fluids, and other water-based industrial production processes for defoaming. Next, the editor of Jianyi Chemical will give you a detailed introduction to the use of defoamers in textile technology production!
1. Textile dyeing defoamer
The outstanding advantage of using defoamers in the entire dyeing process of textile high-temperature systems is that they can be used stably under strong acid and alkali conditions at high temperatures (130 degrees) without breaking the emulsion and causing oil bleaching failure. High product content, low viscosity, and long foam suppression time; The product has good temperature resistance and stability, and is not easy to break or float oil. It is an excellent defoamer and defoamer. It has better defoaming performance in high temperature and high pressure environments, and can be effective at a very low dosage, reducing the time required for the process and thus increasing production.
2. Textile high-temperature defoamer
High temperature resistant self emulsifying defoamer is a non silicone defoamer designed for the entire dyeing process of textiles at high, medium, and high temperatures. Its outstanding advantage is that it can be used stably under strong acid and alkali conditions at high temperatures (60-130 degrees) without breaking the emulsion and causing oil bleaching failure. High product content, low viscosity, and long foam suppression time; Good temperature stability, not easy to break emulsion, not float oil. This product is an excellent defoamer and defoamer. It has better defoaming performance in high temperature and high pressure environments, and can be effective with very low dosage, reducing the time required for the process and thus increasing production. Applied in various high-temperature dyeing processes (such as polyester and cotton dyeing), aqueous systems at 60-150 ℃, strong acid systems, metal cleaning agents, lubricants, printing, high-temperature strong alkali systems, calcium silicate boards, and other high-temperature requirements for silicon free aqueous systems for defoaming.
3. Low viscosity textile pulp defoamer
Hydrophilic defoamers for textile pulp are developed based on the production processes of textile pulp, printing and dyeing pigments, and printing coatings and pastes, and have high molecular weight properties as organic silicon defoamers. Good compatibility with textile acrylic pulp; Outstanding defoaming effect in textile acrylic pulp; It can not only have a good defoaming and foam suppression effect in the size production process, but also have a good role in controlling foam in textile sizing. The characteristics are low dosage, easy dispersion in water, non floating, long-lasting foam inhibition, acid and alkali resistance, suitable for high and medium temperatures, and will not affect the quality of the slurry due to emulsion breaking or reaction with the slurry. Dilute with water before adding during textile sizing, which helps with dispersion and saves on usage.
4. Defoamer for textile pretreatment
The textile pretreatment process is a specialized silicone polyether foam inhibitor developed for the characteristics of textile pretreatment silk penetrant/low viscosity refining agent. Easy to disperse in the system, self emulsifying, resistant to strong alkali, fast defoaming, long-lasting foam inhibition, wide application, and low dosage; Has good compatibility; No side effects, non stick to rollers; The advantages of odorless and non floating.
5. Defoamers for textile dyes
Defoamers are used in textile dye production and throughout the entire dyeing process at medium, high, and medium temperatures. Their outstanding advantage is that they can be used stably under high temperature (130 degrees) strong acid and alkali conditions without breaking the emulsion and causing oil bleaching failure. High product content, low viscosity, and long foam suppression time; The product has good temperature resistance and stability, and is not easy to break or float oil. It is an excellent defoamer and defoamer. It has better defoaming performance in high temperature and high pressure environments, and can be effective at a very low dosage, reducing the time required for the process and thus increasing production. The dosage is small. The dosage is 0.1% -0.5%. An appropriate amount of defoamer can effectively prevent and eliminate foam. Do not use too much. Before use, it should be stirred appropriately and diluted with water or thickening water to obtain the desired defoamer solution before use. Defoamer shall be added before foaming liquid is foamed, so as to prevent foam and eliminate foam more effectively.
6. Defoamer for printing paste
Used in the production process of printing paste, soft oil production, and other high-temperature systems; It has the advantages of convenient use, good compatibility, and small amount of addition. A small amount of addition can significantly improve the foam performance of film products. The defoamer is used throughout the entire dyeing process at medium to high temperatures, and its outstanding advantage is that it can be used stably under strong acid and alkali conditions at high temperatures (130 degrees) without breaking the emulsion and causing oil bleaching failure. High product content, low viscosity, and long foam suppression time; The product has good temperature resistance and stability, and is not easy to break or float oil. It is an excellent defoamer and defoamer. It has better defoaming performance in high temperature and high pressure environments, and can be effective at a very low dosage, reducing the time required for the process and thus increasing production.
