Composition, character and use of Peregal

Periga is a natural admixture of fatty alcohols and ethylene oxide. Structural formula: RO (CH2CH2O) nH.

Fatty alcohol polyoxyethylene ether, levelling agent O, also known as flat plus O, is a non-ionic surfactant, the appearance of milky white or beige paste, high molecular weight, solid (can be made into flake solid according to requirements), easily soluble in water, ethanol, ethylene glycol, etc., there is a turbidity point,1% aqueous solution PH value is neutral. It can resist acid, alkali, hard water, heat and heavy metal salt. It has strong levelling, slow dyeing, permeability and diffusivity for all kinds of dyes, and can be used with all kinds of surfactants and dyes in the same solution.

Product index implementation standard: HG/T 2672-2005

Appearance Milky white, beige paste or solid PH 6-8 turbidity point 91-96

Levelling agent O is widely used in various processes of textile printing and dyeing industry. Levelling agent O is used as a diffuser to prevent the decomposition of certain naftol dyes from accumulating on the fabric and contaminating the color. As a levelling agent for direct dyeing cotton, adding about 0.2-0.5g /L to the solution can obtain good levelling and permeability. Used as a levelling agent when returning dyes dye cotton, the general dosage is 0.02-0.1g /L, levelling agent O can aggregate with dye molecules, thus reducing the dyeing speed of the dye, so that the dye gradually transfer to the fiber, so as to achieve the purpose of levelling. It is used as levelling agent for dyeing wool products with acid complexing dyes. When the acid complex dye (Bertin dye) dyes the fabric, adding the levelling agent O 1-3%, the amount of sulfuric acid can be reduced from 4.7-9.2% to 4.3-5.8%, and the PH value (dye bath) can be increased from 1.9-2.1 to 2.2-2.4, which can ensure that the strength of the fabric is not damaged, and make the feel soft and have the levelling effect. As a dispersive dye dyeing elastic nylon yarn levelling agent, the general dosage is 1-4%.
