Description

Polyester fully drawn yarn device capable of reducing waste yarn

Technical Field

The utility model belongs to the technical field of the dacron chemical fibre spinning production and specifically relates to a dacron that reduces waste silk draws silk device entirely.

Background

The yield of the polyester filament yarns in China reaches 4500 ten thousand tons in 2021 years, the price of the polyester filament yarns is greatly reduced since 2014, a large number of small and medium-sized enterprises break down the halts and sink sands in price wars, and part of manufacturers quit the market. Whether the enterprise has advantages in fierce market competition or not depends on product quality competition, namely competition of continuous potential digging, technology improvement and production cost reduction of the enterprise. The enterprise only through constantly inside digging latent, equipment transformation, the technique promotes, reduces production operation cost, just can constantly promote profit margin, is in the leading advantage in the competition in market.

The terylene Fully Drawn Yarn (FDY) is prepared by a spinning and drawing one-step method, the spinning speed is higher, and the production speed is basically in the range of 4000-6000m/min according to the process requirements of different production varieties. In this high-speed operation state, the problem of threading up is limited by technical equipment and cost, and is a problem that is difficult to solve. The current practice at home and abroad is to adopt a two-step spinning method, namely, spinning at a low speed (2000-3000 m/min), then climbing to a normal spinning speed (4000-6000 m/min), switching a waste silk package after reaching the spinning speed, and entering a high-speed normal spinning package state.

In the production process of the polyester Fully Drawn Yarn (FDY), a large amount of oligomers and silicone oil are generated and condensed around a spinneret orifice, and gradually hardened at a high temperature along with the passage of time to cause damage or breakage of monofilaments, so that a large amount of broken filaments are generated, the spinning condition is deteriorated, and the product quality is reduced. In order to improve the production conditions, the spinneret plate must be periodically cleaned. In the periodic plate cleaning process, the filament bundle needs to be broken to carry out repiece operation, and the repiece operation is a main source of waste filament consumption of chemical fiber enterprises and a main factor of cost increase.

For example, a "yarn winding machine" disclosed in chinese patent document, which is referred to as CN104816984B, has a bobbin holder, and a plurality of bobbins are mounted in line in an axial direction thereof, and a plurality of yarns are wound around the plurality of bobbins, respectively; and a plurality of yarn distributing fulcrum thread guides arranged along the axial direction of the bobbin holder and respectively hooked with a plurality of yarns wound on a plurality of bobbins, wherein when spinning-in is performed on the plurality of yarn distributing fulcrum thread guides, a spinning-in assisting tool holding the plurality of yarns is moved to the plurality of yarn distributing fulcrum thread guides, and spinning-in is performed on the plurality of yarn distributing fulcrum thread guides, respectively.

SUMMERY OF THE UTILITY MODEL
