Preparation method of high-elasticity warm-keeping polyester composite filament

Abstract

The invention relates to a preparation method of a high-elasticity warm-keeping polyester composite filament. Oiling equipment is used comprises a bottom plate, a mounting plate, an oiling device and a recovery box. The specific method for preparing the high-elasticity warm-keeping polyester composite yarn by adopting the oiling equipment comprises the following steps of forming nascent fibers, oiling the nascent fibers, post-processing the nascent fibers, and winding and forming. An oiling device comprises a fixing rod, a rotating cylinder, an auxiliary mechanism, a driving mechanism, an oil storage cylinder, an oiling sponge sleeve, an oil absorption column, a sliding block, an oil baffle plate, a limiting cylinder, a connecting rod, a moving rod and a fixing ring. The oiling device is matched with existing traction equipment to complete oiling work of the nascent fibers, and the oil absorption column and the limiting cylinder are driven to stir lubricating oil through relative movement between the moving rod and the fixing ring in the oiling process; and meanwhile, the attaching tightness between the nascent fibers and the oiling sponge sleeve is increased through the auxiliary mechanism, and the oiling uniformity is improved.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a method for preparing a high-elasticity warm-keeping polyester composite yarn. Background technique [0002] Composite yarn refers to the yarn made of composite fiber. Compared with the yarn made of a single fiber, the composite yarn can combine the advantages of multiple fibers and has better performance. Among them, polyester composite yarn is a new type of yarn. Its good elasticity and warmth retention are favored by people. [0003] The preparation method of polyester composite yarn mainly includes several steps such as spun fiber forming, spun fiber oiling, post-processing, and winding, among which there are some problems in the spun fiber oiling process: [0004] (1) The lubricating oil in the oil storage container is in a static state most of the time, and the lubricating oil is prone to sedimentation, resulting in a large difference between the lubricating oil at the upper posit...

AI Technical Summary

Problems solved by technology

[0004] (1) The lubricating oil in the oil storage container is in a static state most of the time, and the lubricating oil is prone to sedimentation, resulting in a large difference between the lubricating oil at the upper position and the lubricating oil at the lower position. Therefore, the performance of the primary fiber lubricated by lubricating oil cannot be guaranteed to be consistent;

[0005] (2) When oiling the nascent fibers, oil tankers are mostly used to complete the oiling action. Under the traction of the traction equipment, the contact area between the nascent fibers and the oil tanker is small, and the bonding tightness is low, causing the oil tanker to Only a small part of the primary fiber can be oiled, the oiling efficiency is low, and it is prone to uneven oiling
