The production method of the nylon-6 elastic filament yarn, disclosed by the invention, has the following technical effect that a product made from the produced nylon-6 elastic filament yarn has the advantages of good elasticity, comfortable and soft handfeel, good air permeability and low ...
A process for producing polyamides from the corresponding monomers and/or prepolymers comprises the steps of (a) reacting the monomers and/or prepolymers and optionally further components under polyamide-forming reaction conditions to form polyamide, (b) treating the polyamide obtained in step (a) ...
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....
摘要: Nylon 6 chip is obtainable by hydrolytic polymerization of caprolactam in the presence of dicarboxylic acids as chain regulators, subsequent processing of the polymer melt into chip, extraction of the low molecular weight portions from the chip with water and subsequent drying of the chip....
The production of nylon-6,6 on the contrary requires two monomers and is much less simple; consequently the uneconomical batch process for the production of nylon-6,6 is still in use today. A one-step process is also discussed for the production of nylon-6 filaments. 被引量: 1 年份: ...
