Problems solved by technology

[0003] Polyimide fiber is a high-performance flame-retardant fiber with a limiting oxygen index of 38%. It is a non-combustible fiber, and the long-term use temperature of polyimide fiber is 260°C. Generally: guide cylinder→warping→drawing-in heald→on machine→weaving→finishing (washing, heat setting, etc.)→piece inspection→finished product, etc. In the traditional setting process, the setting temperature generally does not exceed 200°C. The time is about a few seconds. The time for the fabric to pass through the sizing machine is very short, and the contact temperature is relatively low, which cannot meet the sizing requirements of polyimide fabrics. Therefore, a new sizing process is designed, which is suitable for polyimide fabrics. The shaping process is an indispensable step, which has certain guiding significance for the development of polyimide downstream products in the future

Abstract

The invention provides a highly protective polyimide flame-retardant garment fabric and a heat setting method thereof and relates to the technical field of flame-retardant fabrics. The highly protective polyimide flame-retardant garment fabric is prepared from an inner layer and an outer layer through sewing. The inner layer is prepared from polyimide fiber yarn and flame-retardant filaments through weaving. The outer layer is a cloth surface with raised grids and is prepared from polyimide fiber yarn and flame-retardant filaments through weaving. The highly protective polyimide flame-retardant garment fabric has good fire resistance and heat-insulating functions, can be used at a high temperature for a long time, is comfortable, and reduces hair slip. Through heat setting, the fabric is smooth and flat and size stability.

Description

technical field [0001] The invention relates to the technical field of flame-retardant fabrics, in particular to a high-protection polyimide flame-retardant clothing fabric and a heat-setting process. Background technique [0002] With the progress of human society and the development of science and technology, people's living environment is surrounded by various high-rise buildings and high-tech products. In daily production and life, the form and frequency of fire are no longer single. The environment tests the rescuers, and the overweight fireproof clothing also limits the mobility of the rescuers, and the physical exertion of the rescuers is also relatively large. Therefore, it is of great value and significance to develop a fire-resistant clothing with high protective performance, comfortable wearing and light weight for the rescuers who shuttle on the front line of the fire scene. [0003] Polyimide fiber is a high-performance flame-retardant fiber with a limiting oxy...
