Ultra-black large-melt-index high-dispersity black master batch special for direct spun fine-denier filaments

Abstract

The invention discloses an ultra-black large-melt-index high-dispersity black master batch special for direct spun fine-denier filaments. The ultra-black large-melt-index high-dispersity black masterbatch is composed of the following components by weight: 25-30 parts of ultra-black carbon black, 74-67 parts of a polyester carrier and 1-3 parts of a dispersing agent. The black master batch provided by the invention is special for direct spun fine-denier filaments, and has ultra black, large melt index, and high dispersity performance.

Description

technical field [0001] The invention relates to an ultra-black large-melt finger high-dispersibility black masterbatch specially used for direct-spinning fine denier yarns. Background technique [0002] With the wide application of on-line dope coloring technology in melt direct spinning production lines, the requirements of spinning mills for black masterbatch no longer only stay in the aspects of less spinning breakage and long component cycle, but "more Black is more blue and better to use" as the main goal. This infinite pursuit of "there is no blackest but darker" puts forward higher requirements for the production and preparation of masterbatches, and also increases the difficulty of masterbatch production. Contents of the invention [0003] The object of the present invention is to provide a kind of black masterbatch, which is specially used for direct spinning fine denier yarn, and has super black big melt finger and high dispersion performance. [0004] In order...
