HT Fine Textile Chemical Auxiliary Agent

  Introduction for the functions of all kinds of soaping agent   Surfactant is the core part in the formulation of soaping agent. It has the function as dispersion, emulsification and solubilization. Anionic surfactants commonly used are sulfonate, sulphate, carboxylate and phosphate. Nonionic surfactant has polyethylene glycol group, polyoxyethylene fatty acid, polyol ester and polyoxyethylene sorbitan fatty acid esters on its surface.   Through so many years of research and sales experience, Ke Feng Textile auxiliaries Industrial Co., Ltd.now have soaping agents like white prevent soaping agent for reactive dyes, low temperature soaping agent, natural polymer modified soaping agent and soaping agent for acid dyes.   1. Soaping agent for acid dyes   Soaping agent for acid dyes with polymer compound have strong incompactness and chelating ability and strong affinity of the hydrolysis  reactive dyes and reactive unfixed dyes,and can reduce the production pro...

  Definition of Silicone Softeners Softener is a compound of organic polysiloxane and polymer, which is suitable for soft finishing of natural fibers such as cotton, wool, silk, hemp and human hair. Silicone textile finishing auxiliaries have a wide application in textile finishing. The auxiliary can not only deal with natural fabrics, but also deal with polyester, nylon and other synthetic fibers. After treatment, fabric is anti-wrinkle, anti-fouling, anti-static, anti-pilling and plump, soft, elastic and glossy, with a smooth, cool and strong style. Silicone softening finishing can also improve the strength of fiber and reduce abrasion. Silicone softener is a promising fabric softener, which is also an important additives to improve product quality and add value in textile dyeing and finishing processing.   Silicone Softeners features Soluble in water, aqueous solution is very stable and in good compatibility; The fabric feels soft, smooth and full, and has good drape and pu...

  Definition of sequestering agent Sequestering agent, also known as chelating agent, is a complex forming auxiliary chemical with metals such as Iron, Copper, Nickel, Zinc and Magnesium that are present in water and affects the textile processing in many way.   Functions of sequestering agent in textile process 1. Applications of sequestering agent in textile industry 1) Desizing Adding sequestering agent into whatever kind of desizing agent can improve the efficiency of desizing. This is because it complexes metal ion that reacts with size, improving swelling capacity of size membrane and reactivity of  size and sequestering agent. Thus it is easy to be removed from fabrics.   2) Pretreatment Mainly use stabilizing agent for hydrogen peroxide bleaching to make hydrogen peroxide resolve smoothly and then improve usage rate of it; at the same time cause the fracture of fabric fiber and form holes. 3) Dyeing Water, glauber salt, sodium carbonate, sodium chloride and e...

  Definition of scouring agent in textile   Scouring agent in textile refers to a large number of auxiliaries with functions of emulsifying, penetrating, washing, dispersing and wetting in the scouring process before dyeing and printing, in order to remove oil stains and impurities from the textile fibers. The common scouring agents include sizing agent, lubricating agent, oil stains agent, alkali-resistant agent, mercerizing agent, wax removing agent, penetrating agent and so on. The required property of scouring agent varies depending on materials, fabric structure, stains and applications.   Scouring agent is a non-toxic, tasteless, pollution-free white powder, soluble in water whose aqueous solution is alkaline, capable of cleaning, emulsification, dispersion, wetting, penetration and the pH buffering. It belongs to the inorganic alkali products, easily hygroscopic when placed in the air, sometimes there existing a little bit block, which is a normal phenomenon with n...

  polyethylene wax emulsion is a soft finishing agent with special function in textile processing. Its main components are low molecular weight polyethylene (molecular weight of 1000 ~ 3000), which is also known as polyethylene wax.   Making proper oxidation of polyethylene wax under certain conditions and introducing a certain amount of carboxyl, hydroxyl and other oxygen-containing functional groups in the molecule will improve its hydrophilic, make it into stable emulsion and reduce the dosage of emulsifier. The oxidation-modified polyethylene wax is called oxidized polyethylene wax.   Suitable emulsifier can be used to transform the oxidized polyethylene wax into white emulsion and polyethylene wax emulsion can be made after further process. Characteristics and Application of Polyethylene Wax Emulsion   ( 1 ) Characteristics It is compatible with other auxiliaries and can be used in bath with different ionic auxiliaries.   Polyethylene wax is of high tempera...

  Definition of non formaldehyde dye fixing agent At present, color fixing agent can be divided into cationic fixing agent, resin type fixing agent (containing formaldehyde resin type fixing agent containing polyamine resin type fixing agent) and cross linking reaction type fixing agent.   The mechanism of color fixing agent which can improve the dyeing fastness of dye solution on the fiber is through   (1) the quaternary ammonium salt or tertiary amine salt in color fixing agent molecules, when in acidic medium, relying on a combination of anionic ionic bond strength of cationic and anionic dyes in the structure and form insoluble fiber deposition in the inside and outside the lake;   (2) reactive binding groups in color fixing agent molecules covalently links active group covalent bond in fibers and dyes;   (3) Fabric which is treated by color fixing agent  in the drying process, the reactive binding group on the color fixing agent molecules associate gro...

  Mercerizing agent  is used to deal with wool and cashmere, it can stop textile from being yellowish and is good at removing scale of wool. It is harmless to human body. Mercerizing The process of using concentrated caustic soda solution to deal with Cotton goods ( yarn or fabric) under the condition of remaining its tension and then wash the caustic soda solution away. Alkali shrinkage The process of using concentrated caustic soda solution to deal with cotton goods when it is slack to make fibers shrink at random and then wash the caustic soda solution away. This process also called free tension mercerizing and is mainly used for the process of cotton goods. Traits of fabric with mercerizing and alkali shrinkage Fabric have the following traits after the process of mercerizing 1.High smoothness 2.High adsorb capacity and chemical reaction capacity. 3.Shrinkage rate,dimensional stability and flatness improved 4.Strength, extensibility and other mechanical property changed Al...
