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 virgin fibers, oil tankers are mostly used to complete the oiling action. Under the traction of the traction equipment, the contact area between the virgin fibers and the oil tankers is small, and the bonding tightness is low, causing the oil tankers to Only a small part of the primary fiber can be oiled, the oiling efficiency is low, and it is prone to uneven oiling

Abstract

The present invention relates to a method for preparing high-elasticity warm-keeping polyester composite yarn, which uses an oiling equipment, the oiling equipment includes a bottom plate, a mounting plate, an oiling device and a recovery box, and the above-mentioned oiling equipment is used to prepare high-elasticity warm-keeping polyester The specific process of the composite yarn is as follows: spun fiber forming, spun fiber oiling, spun fiber post-processing and winding molding, the oiling device includes a fixed rod, a rotating drum, an auxiliary mechanism, a driving mechanism, an oil storage cylinder, and an oiling sponge sleeve, oil suction column, sliding block, oil baffle, limit tube, connecting rod, moving rod and fixed ring. The invention uses the oiling device to cooperate with the existing traction equipment to complete the oiling work of the primary fiber. During the oiling process, the relative movement between the moving rod and the fixed ring drives the oil absorption column and the limit cylinder to stir the lubricating oil, and at the same time The bonding tightness between the primary fiber and the oiling sponge cover is increased through the auxiliary mechanism to improve the uniformity of oiling.

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...
