Example Embodiment

[0019] The specific implementation of the present invention will be further described below in conjunction with examples. The following embodiments are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.

[0020] The technical scheme of the present invention is:

[0021] An ultra-black large melt index high-dispersion black masterbatch special for direct spinning fine denier yarn, which is composed of the following components in parts by weight: 25-30 parts of special black carbon black, 74-67 parts of polyester carrier, 1-3 Parts of dispersant.

[0022] The model of the special black carbon black is 26#black, 89#black or 534#black.

[0023] The primary particle size of the special black carbon black is 19-20 nm.

[0024] When preparing the special black carbon black, a carbon black coating agent is added during the carbon black granulation process.

[0025] The polyester carri...

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...
