Description
Technical field
The present invention relates to the processing technique of a kind of same plate double-colored superfine composite polyester fiber, belong to long filament generation technique
Field.
Background technology
Sea-island composite fiber, compared with general fibre, has minimum line density and high-specific surface area, is made into
Fabric has the characteristics such as high spreadability, soft, comfortable and easy to wear, tone is soft, be widely used in suede nap,
Imitative peach face, superfine fiber leather base fabric, highly dense waterproof fabric, high-performance cleaning cloth, high-performance suction strainer material
Deng production, become the product that added value is higher.Island superfine fiber has above-mentioned numerous premium properties and use
While Tu, there is also following deficiency: be 1. difficult to dye dark color: sea-island composite fiber, due to fiber finer, compares table
Area is big, and the colour developing efficiency of dyestuff is low, i.e. color rendering properties is poor.In order to obtain the same color degree of depth, superfine fibre contaminates
Color often wants several times higher than general fibre by amount of dye, obtains dark product surely even if so also differing, as deeply
Black, dark blue etc.；2. dyefastness is poor: the dyefastness of superfine fibre textile is typically poor than conventional fibre, bag
Include sun-proof, washable and fastness to sublimation.The main still fiber finer of its reason, specific surface area are big, therefore to select
The dyeing that color fastness is good, and the dye species that really can promote island-in-sea fabric color fastness at present is little.
Application number 201310146982.0 discloses " preparation method of a kind of atrous island polyester fully drawn yarn ",
By adding the original liquid coloring technology of black agglomerate, it is achieved that the production of atrous island superfine fiber.But mesh
During road application front and back, often by black island and white sea-island fibre network again plying, to produce, there is special color
Color effect and the fabric of style.This two step method plying the method for silk, need to through debatching, network combined, roll up again
Around process, there is the drawback such as technological process length, impaired, the cost increase of product quality.
Based on this, make the application.
Summary of the invention
For the deficiencies in the prior art, it is provided that the processing technique of a kind of double-colored polyester fiber of same plate, this technique is adopted
