composition analysis of textile printing and dyeing auxiliaries

textile printing and dyeing auxiliaries are chemicals necessary in the production and processing of textiles. textile printing and dyeing auxiliaries play an indispensable and important role in improving the product quality and added value of textiles. they not only can give textiles various special functions and styles, such as softness, anti-wrinkle, anti-shrinkage, waterproof, anti-bacterial, anti-static, flame retardant, etc., but also can improve the dyeing and finishing process and play the role of saving energy and reducing processing costs. printing and dyeing auxiliaries are auxiliaries used in the process of printing and dyeing fabrics, which can improve the effect of printing and dyeing, including printing auxiliaries and dyeing auxiliaries, printing auxiliaries include binders, thickeners, crosslinkers, emulsifiers, softeners, diffusers and defoamers, etc. dyeing auxiliaries include leveling agents, color fixing agents, dispersants, fluorescent brighteners and softeners, etc.

china's printing and dyeing auxiliaries production is progressing with the development of the textile printing and dyeing industry. 90s since the development of new fibers, innovation in textile technology, the increase in consumption levels and exports have forced the textile industry to seek new auxiliaries, a new business model. from the beginning of imports to national development and production, gradually formed the chemical and textile industries cross each other in the printing and dyeing auxiliaries production industry prototype. today's rapid changes in the product towards high-grade, comfortable, healthy and ecological green direction.

the development trend of textile printing and dyeing auxiliaries have four major aspects: the development of new fibers according to the corresponding supporting auxiliaries; the use of compounding technology to increase the multi-functionality and high functionality of the auxiliaries; the use of high-tech products to complement and improve the traditional textile printing and dyeing auxiliaries products; the development of environmentally friendly auxiliaries. to meet the new development trend, the textile printing and dyeing industry needs to continuously inject fresh blood to maintain the diversified development of production and operation. in short, the development of printing and dyeing auxiliaries to take a high-tech information technology diversified business road, we need to continue to explore and discover in the way forward, in order to higher and better development.

q&a

polypropylene oil agent is commonly used in the production process of polypropylene, what is its role and mechanism of action?

polypropylene is hydrophobic fiber, no polar groups in the molecule, its moisture absorption and electrical conductivity are very poor. in the spinning process, the fiber and fiber and fiber and spinning equipment is very easy to generate static electricity, and the generation of static electricity is difficult to channel out in a timely manner, so that the production process is easy to produce hairy silk, broken head phenomenon, affecting the normal production. therefore, it is necessary to apply a layer of oil on the fiber surface to protect the surface of the fiber and to channel the static electricity to ensure the smooth operation of the production processes.

textile dyeing and printing need to go through a certain cooking process before, the process is often added to the refining agent, what is the purpose?

the purpose is to let the refining agent penetrate inside the fiber, promote the emulsification and dispersion of waxes and greasy substances, and further emulsify and disperse the impurities that have been separated from the fiber in the refining bath to prevent re-attachment to the fiber.

what are the basic ingredients of refining agents, which are crucial in the textile printing and dyeing industry?

according to the classification in the textile industry, cotton, linen, silk, wool, man-made fiber, synthetic fiber fabrics are different, the components and ratios of the refining agent are also different. but the basic components are no more than alkali agent, penetrating agent, emulsifier, detergent, dispersant, metal ion complexing agent and appropriate neutral salt.

what is noa's solution to the problem of uneven staining during the staining process?

during the dyeing process, the proportion of homogenizing agent can be adjusted appropriately according to the situation, the homogenizing property of polyoxyethylene ether type surfactant is worse than that of polyoxyethylene ester type surfactant, and the homogenizing property of surfactant with benzene ring type is better than that of aliphatic hydrocarbon surfactant, which can also be solved by adjusting the homogenizing agent. optimization, raw material recommendation, process guidance and other technical services to help enterprises achieve product performance improvement and reduce production costs.
