The present invention relates to a process for producing nylon-6,6 by a) providing a muconic acid starting material selected from muconic acid, esters of muconic acid, lactones of muconic acid and mixtures thereof, b) subjecting the muconic acid starting material provided in step a) at least...
Process for making nylon 6 in which a feed stream containing a major portion of caprolactam and/or nylon 6 prepolymer and a minor portion of aminocapronitrile is fed to a multistage reactive distillation column in which the feed stream flows countercurrently to a steam stream....
A production process is characterized by including the steps of 1, after parallel combining, thermally drafting a nylon 6-6 as-spun fiber UDY (undrawn yarn) product and the nylon 6-6 and carbon black combined conductive fiber on a hot drafting roller; and 2, feeding the drafted combined ...
Process for the production of a multifilament texturized yarn A process for the production of a multifilament textured yarn by melt- spinning different polymers (for example a polyamide and a polyester) or copolymers (for example copolymers of nylon-6 and nylon-6,6) to form a highly preoriented...

that can wear off over time. The yarn has a bicomponent structure featuring one-part nylon 6,6, and one-part conductive carbon. These two components are joined together during the high-temperature yarn extrusion process to produce a fiber that, among other attributes, eliminates static ...
The method aims to solve the problem in the production of the prior dulling agent solvent. The method has the technical scheme that (1) a proper TiO2 and TiO2 solution collocation method is selected; (2) proper formulation and process are selected; and (3) a stirring device for dispersing...
Investigation of the composite recycling process for nylon 66. As environmental awareness increases around the world, the concept of recycling used materials has been widely accepted and implemented. Polyamides, specif... MJ Wright - Queen's University at Kingston (Canada). 被引量: 0发表: 2005年...
