Oligomer inhibitor

Image
Oligomer inhibitor is one type of dyeing auxiliaries, especially produced in order to prevent polyester oligomer in case of bad effect to dyeing process. Here is the details: [Main composition]  Surfactant compound with content. [General properties] Appearance: Pale transparent liquid Ionicity: Anionic Solubility: Easily soluble in water. [Oligomer Inhibitor  Features] Can prevent deposit of oligomer and Gel dyeing on machinery and fabric,can be used to remove polyester processing produce deposition oligomer and dye. [Application] Suitable for polyester fibre dye processing and reduction cleaning process. 1. Remove the deciduous polyester after treatment of caustic soda reduces weight. Recommended usage 1~3g/l. 2. Oligomer removal: used for scouring or reduction detergent washing. A) Use simultaneously with scouring agent, remove oligomer when spinning: 0.5 ~ 1 g/L. B) Used for reduction detergent washing (caustic soda, soda ash, sodium hydrosulfite), remove oligomer when d...

Fixing Agent for Acid Dyes SP

Image
[ Fixing Agent for Acid Dyes  General Information] Fixing agent for acid dyes will be deposited on the surface of the fiber, plugging the pores of acidic dyes dissolved again, thus reducing the possibility of fading, and generally improving the color fastness 1 ~ 1.5. Based on this, the solid color of the impregnation method is used. The appearance is generally brown liquid, pH value (1% water solution) 2.0-4.0, anionic, odorless, slightly special smell, taste astringent, deeper color while exposed under light and in air. Soluble in water, soluble in ethanol, acetone and glycerin, almost insoluble in ether, benzene, chloroform and petroleum ether. It has strong hygroscopicity. Decompose in 210 ~ 215 ℃, It can produce insoluble salt with copper, aluminum, iron, tin, chromium and metal salts, and each has its own special color. It is best to use soft water or add 1 g/L 6 sodium phosphate when used. [Main composition]  Sulphonate condensation polymer. [General properties...

Auxiliaries for Acrylic

Image
Brief introduction of chemicals for acrylic Dyeing auxiliaries  is mainly included auxiliary for cotton, auxiliaries for polyester, auxiliaries for wool and nylon, auxiliaries for acrylic etc. Properties of acrylic fiber is wool, so called "synthetic wool". With good thermal elastic acrylic (acrylic bulked yarn processing), low density, smaller than the wool fabric, warm and good. Sunlight resistance and weather resistance is very good (ranking first), poor moisture absorption, dyeing difficult. Mainly used for civilian, pure spinning can also be made into a variety of blended wool, wool, blanket, sportswear or artificial fur, plush, yarn, hose, umbrella cloth and so on. Acrylic fiber artificial wool. With a soft, bulky, easy to dye, bright color, light, antibacterial, not afraid of insects and other advantages, according to the requirements of different applications can be pure spinning or with natural fiber, the textile is widely used in clothing, decorat...

The Types Of Dye-Fixing Agent

1. Reactive dye-fixing agent Reactive fixing agent is usually introduced reactive group in the fixing agent molecules,the commonly used reactive group here is the epoxy group. This dye-fixing agent will combine some groups in fiber dye molecules and form covalent bond, which is helpful to the fastness. The commonly used reactive dye-fixing agent is as follows: (1)The reactive cationic resin type fixing agent is usually produced by the reaction of diethylenetriamine , dicyandiamide and the epichlorohydrin (the introduction of epoxy group). It can not only improve the color fastness of direct dyes and acid dyes, but also does not change the color. (2)Polyether reactive fixing agent, is a kind of non-ionic polyether fixing agent produced by the reaction of polyether and epichlorrohydrin. This agent has a certain solubility in water. It can be cross-linked into macromolecular network structure in itself. Combining with dye, it will form large molecular compounds. the dye and fiber comb...

Part II: Influence Of Dye Fixing Agent For Cotton Reactive Dyes Brightness

Experimental result andconclusion 1.The   fixing agent ' s influence on the glossiness of dark green dye textile When we dye the dark blue textile with RemazolRR as color matching, the textile’s glossiness changes largest dealt by 1# dye fixing agent, and smallest by dealt by 4# dye fixing agent. All 4 types of dye fixing agent make the glossiness of textile  reddish and bluish to varying degrees. The changes is smaller for Remazon RGB than for remazonlRR, but dealt with the RemazonlRR will cause a little bit greenish. When we use Sumifix matching color, the color glossiness change for dye fixing agent 1# is largest compared with other 3 dye fixing agent. The dye is yellowish compared with RemazolRR, RemazolRGB, that means the shortage of blue light. 2.The fixing agent's influence on the glossiness of garnet textile When we dye the garnet textile with RemazolRR as color matching, the textile’s glossiness is bluish obviously. ...
