Preparation method of super-soft and super-fine polyester filament yarn

Abstract

The invention discloses a preparation method of a super-soft and super-fine polyester filament yarn. The preparation method comprises the following steps: preparation of POY protofilaments, pre-interlacing, processing with a first thread feeding roller, processing with a first deformation heat box, processing with a cooling plate, processing with a false twister, processing with a second thread feeding roller, medium interlacing, processing with a second heat box, processing with a third thread feeding roller, processing with a finish application roller, winding formation of DTYs and inspection of a spinning cake. In the preparation method, the process of pre-interlacing is added between the preparation of the POY protofilaments and the step of processing with the first thread feeding roller, so that the cohesive property and the draping property of fibers can be effectively improved, the processed polyester filament yarn is upright in strands and good in bundling and is favorable fornaps of subsequently woven fabric to be upright, and the super-soft and super-fine style is met; the temperature of the second heat box is controlled to 160-180 DEG C, so that the strands are set by high temperature more fully, are not dispersed easily and do not have the phenomena of hair adhesion and nap collapse, and the style of flannel fabric is met; cotton fabric is substituted easily, so that the super-soft and super-fine polyester filament yarn has wide market prospect and remarkable economic benefit.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a preparation method for supersoft and superfine polyester filaments. Background technique [0002] At present, the ordinary polyester DTY products on the market are not soft enough to weave, easy to fall or stick to the wool, and fail to meet the comfort and hand feeling required by the market. The cotton fabrics on the market are not comfortable, hand-feeling Sensitivity and visual or tactile effects can meet people's requirements, but because of its limited resources and high price, it has not been widely used. [0003] Patent No. CN101270503 "A Bright Polyester Filament Production Technology That Can Replace Nylon" discloses the production technology of bright polyester filament instead of nylon, mainly to make the glossy polyester filament elongation higher than 40 %, to achieve the effect of nylon, there is no way to make polyester filaments more supple, strai...

[0002] At present, the ordinary polyester DTY products on the market are not soft enough to weave, easy to fall or stick to the wool, and fail to meet the comfort and hand feeling required by the market. The cotton fabrics on the market are not comfortable, hand-feeling Sensitivity and visual or tactile effects can meet people's requirements, but due to its limited resources and high price, it has not been widely used

[0003] Patent No. CN101270503 "A Bright Polyester Filament Production Technology That Can Replace Nylon" discloses the production technology of bright polyester filament instead of nylon, mainly to make the glossy polyester filament elongation higher than 40 %, to achieve the effect of nylon, and did not give a method to make polyester filaments more supple, straight and non-linting
