Abstract

The invention discloses a dissolved air type spinneret. The spinneret comprises a main pipe body (10), wherein the main pipe body (10) comprises a feeding segment (11), an air inlet segment (12), a slow flow segment (13) and a spinning segment (14) which are sequentially disposed; the air inlet segment (12) is connected to air pipes (20); the inner diameter of the slow flow segment (13) is greaterthan those of the air inlet segment (12) and spinning segment (14). The spinneret has the advantages that spun silk is easy to twist, and the elasticity and the water absorption performance are good.

Description

technical field [0001] The invention relates to a spinneret of a melt spinning fiber spinner in the textile industry, in particular to a dissolved air spinneret. Background technique [0002] Chemical fibers are fibers with textile properties that are made from natural polymer compounds or artificially synthesized polymer compounds through the processes of preparing spinning dope, spinning and post-treatment. The spinning methods of chemical fibers mainly include melt spinning, wet spinning and dry spinning. The main process of melt spinning is that the melt is extruded through the spinneret hole to form a melt stream, and the melt stream is cooled and solidified to form a primary fiber. . The surface of the filaments ejected from the existing melt-spinning spinneret holes is continuous and smooth. The adhesion of this silk thread is low when twisted, and the yarn after twisting is easy to be fluffy, which affects the appearance effect of the product. At the same time, the...
