Description
Technical Field
The invention relates to the technical field of textile yarn dyeing, in particular to a polyester dyeing additive suitable for children clothing fabric.
Background
From the view of the composition of terylene molecules, the terylene is composed of short aliphatic hydrocarbon chains, ester groups, benzene rings and terminal alcoholic hydroxyl groups. Except two terminal alcoholic hydroxyl groups, the terylene fibers have no other polar groups, so the hydrophilicity of the terylene fibers is very poor. The terylene molecule contains about 46 percent of ester groups, the ester groups can be hydrolyzed and thermally cracked at the temperature of more than 200 ℃, the ester groups can be saponified when meeting strong alkali, so that the polymerization degree is reduced, and the common detergent powder with the dosage of less than 100 ℃ has no influence on the terylene; the terylene molecules also contain aliphatic hydrocarbon chains, which can make the terylene molecules have certain flexibility, but because the terylene molecules also contain benzene rings which can not rotate, the terylene macromolecules are basically rigid molecules, and the molecular chains are easy to keep linear. Therefore, the polyester macromolecules are easy to form crystals under the condition, so that the crystallinity and the orientation of the polyester are high. Due to the structural characteristics of terylene, the terylene has poor dyeing property, good color fastness and difficult fading. The terylene molecular chain has no specific dyeing group and has small polarity, so the terylene molecular chain is difficult to dye and has poor dyeability, and dye molecules are difficult to enter fibers.
The traditional polyester fabric needs to be subjected to high-temperature pretreatment before dyeing to remove spinning oil, stains, sizing agents and the like, the polyester fabric can be dyed in a high-temperature and high-pressure dyeing machine after pretreatment processing through washing and neutralization procedures, the fabric is dyed at the high temperature and the high pressure of 150 ℃ by adopting 100-plus-material high-temperature dyeing in the high-temperature and high-pressure dyeing machine, and the middle-depth fabric needs to be subjected to reduction cleaning processing after dyeing is finished to remove loose colors and improve washing fastness. The traditional pretreatment and dyeing process has long working procedures, uses a large amount of water, electricity and steam, and simultaneously discharges a large amount of sewage and pollutants.
In order to improve the environmental protection performance of the polyester yarn dyeing process, reduce pollution and ensure that the prepared polyester yarn is safer and healthier, the invention provides the polyester dyeing additive suitable for the children clothing fabric.
