Abstract

The invention relates to a method for preparing a drafted filament, in particular to a sizing-free method for preparing the drafted filament and a special device. The method mainly solves the technical problems that excessive twisting damages the appearance of fabric and sizing causes environmental pollution and increases the processing cost and the like of the prior art. The preparation method comprises that: a pre-oriented polyester yarn passes through a hot disc, a hotplate and a lower hot disc sequentially; the drafted polyester filament is prepared in a parallel drawing machine; the drafted filament is sent into an airflow tow collecting device to obtain the network drafted filament with high density; and then, a tow collecting agent and an anlistatig are added into the network drafted filament to obtain the sizing-free drafted polyester filament.

Description

technical field [0001] The invention relates to a preparation method of drawn filaments, in particular to a sizing-free preparation method and a special device for drawn filaments. Background technique [0002] When polyester filaments are used as warp yarns for weaving, in order to improve weaving efficiency and ensure fabric quality, the weavability of warp yarns is usually improved by twisting, sizing or network bundling. [0003] The network method is a more practical method for processing medium-thick polyester low-elastic wool-like fabrics. This is because medium-thick wool-like fabrics can be weaved without sizing through traditional network methods. China Jinan Chemical Fiber Corporation has studied the process parameters of producing DTY network yarn on SDS-400 equipment, and discussed the production process of DTY network yarn without sizing during weaving. Sizing achieves the purpose of not needing desizing before dyeing, reduces production cost and improves eff...
