Spinning additive capable of effectively improving spinnability of color spinning and colorizing quality

Abstract

The invention provides a tackifying spinning promoter and an adding method which are used to improve the defects of the poorer spinnability and the poor colorizing quality of color filament caused by adding master batch during the color wire production. Liquid or solid tackifying promoter is added in mixed melt body for the spinning to obtain a finished product according to the general color wire production process. The adding of the promoter can effectively regulate the viscosity of polymer within the process requirement. Therefore, the melt body obtains good spinnability. And the finished product has the advantages of non broken filament, good dyeing evenness, beautiful color and softer touch feeling.

Description

technical field [0001] The invention relates to an auxiliary agent for chemical fiber spinning, which belongs to the technical field of textile chemical industry. Background technique [0002] Color masterbatch is an aggregate made by uniformly loading super-normal pigments in resin. Color masterbatch is generally composed of three parts: colorant, carrier, and dispersant. These components are mixed by a high-speed mixer, crushed, extruded and drawn into granules. In the process of plastic processing, masterbatch has significant advantages such as high concentration, good dispersibility, and cleanliness. [0003] 1. Make the pigment have better dispersibility in the product [0004] During the production of color masterbatches, the pigments must be refined to improve the dispersion and tinting strength of the pigments. The carrier of the special color masterbatch is the same as the plastic of the product, and has good matching. After heating and melting, the pigment parti...

Problems solved by technology

[0015] We know that in the production process of spinning colored silk by adding color masterbatches, due to the addition of color masterbatches, the color difference agent plays a plasticizing role in the melt, reducing the internal density of the melt macromolecules. Mocha force greatly reduces the intrinsic viscosity of the melt, which is between 0.65g / dl of the original melt such as polyester and 0.35g / dl of the masterbatch, especially for spinning bright red, indigo and other color masterbatches For the color system with large content, the viscosity of the melt will decrease more, and the excessive decrease of viscosity will affect the spinnability of the melt, resulting in a great decrease in the tension of the finished yarn
