Problems solved by technology

[0005] The above method is still only a one-step production technology for two-color fibers. For multi-color fibers with more than or equal to three colors, a two-step method of plying is still required in the subsequent process.
[0006] However, existing technologies such as application number 032345356 and application number 2008100636505 form fibers with different cross-sectional shapes or different color combinations by means of sea-island silk spinning or water-soluble material properties. However, this method has special requirements for raw materials, and its products The variety is limited, the microstructure of the fiber itself is destroyed, and the mechanical properties cannot meet the needs of use

Abstract

The invention relates to a processing technology of a veneer multi-difference polyester fiber. The processing technology of the veneer multi-difference polyester fiber belongs to the technical field of filament yarn generation. The processing technology comprises the following steps of adopting a normal polyester as a raw material; after melting and extruding through different screw extruders respectively, entering a three-component spinning component; spraying out from a same spinneret plate; carrying out a one-step spinning method including cooling, oiling, drafting, heat setting and winding to obtain the multi-difference polyester fiber. The processing technology of the veneer multi-difference polyester fiber provided by the invention can be applied to the processing of fiber forming and fabric processing, and has the advantages of short technological process, high product quality, low cost, and no need of post-dyeing.

Description

technical field [0001] The invention relates to a processing technology of veneer polyisopolyester fiber, which belongs to the technical field of filament production. Background technique [0002] While polyester has many excellent properties, it also has the disadvantage of poor dyeability. Generally, it can only be dyed with disperse dyes at high temperature (120-135°C) and high pressure or in the presence of carriers, and the dyeing cost is high and wastewater treatment is difficult. Therefore, the direct production of dope-dyed yarn by adding pigments or color masterbatches in the melt spinning stage has been increasingly adopted by fiber manufacturers, and has also become an object of national encouragement and development. Dope dyed fiber has the advantages of high color fastness, uniform color and bright color. For example, taking advantage of the advantages of high color fastness, it is widely used in automotive interior fabrics, curtains, etc.; therefore, the socia...
