Embodiment 1

[0040] A preparation method for thermal underwear fabric, comprising the following steps:

[0041] (1) Preparation of hollow warm and lightweight composite fiber:

[0042] Extrude the PET melt with an intrinsic viscosity of 0.6dL / g from the spinneret holes on the spinneret and cool it with ring blowing, and make FDY filaments according to the FDY process, which is the hollow, warm and lightweight composite fiber;

[0043] Among them, the spinneret hole is a C-shaped spinneret hole, and the cross-section of the C-shaped spinneret hole is surrounded by an outer arc M, an inner arc N, and two line segments. The equivalent diameter of the C-shaped spinneret hole is 0.2mm, and the diameter of M The two ends are A and B respectively; M is divided into four sections AE, EJ, JD and DB connected in sequence, the central angles of AE, EJ, JD and DB are equal, and all C-shaped spinneret holes are divided into four categories, with The first point of contact with the cooling air is the f...

Abstract

The invention relates to a method for preparing thermal underwear fabrics. After interweaving hollow thermal insulation lightweight composite fiber yarns, cotton yarns and fine denier PET fiber yarns into knitted gray fabrics, the thermal underwear fabrics are sequentially dyed, brushed and shaped; hollow thermal insulation The lightweight composite fiber is produced by extruding PET melt from the spinneret holes on the spinneret and cooling it with ring air, according to the FDY process, wherein the arrangement of the spinneret holes on the spinneret meets specific conditions; The thread hole is a C-shaped spinneret hole. The cross-section of the C-shaped spinneret hole is surrounded by an outer arc M, an inner arc N and two line segments. The two ends of M are A and B respectively. The preparation method of the thermal underwear fabric of the present invention has simple process and low cost, and can simultaneously endow the underwear fabric with better lightness, comfort and warmth retention.

Description

technical field [0001] The invention belongs to the technical field of textile fabrics, and relates to a preparation method of thermal underwear fabrics. Background technique [0002] Underwear refers to clothing worn next to the body, including vests, undershirts, shorts, bras, etc. Underwear refers to clothes worn under other clothes, usually in direct contact with the skin, and is one of the indispensable clothing of modern people. [0003] With the development of the market and the continuous improvement of living standards, people have higher and higher requirements for various fabrics. Not only are underwear fabrics required to have better warmth retention, but also a relatively high lightness and comfort. Traditional thermal underwear fabrics are generally made of wool, kapok fiber, etc., and usually adopt a thicker design. Although the warmth retention is good, there are problems such as too heavy clothes, poor comfort and breathability. [0004] Therefore, it is o...
