Flame-retardant fabric refers to a fabric that can be automatically extinguished within 12 seconds after leaving the open flame even if it is lit by an open flame. According to the processing sequence, it can be divided into two types of pre-treatment flame-retardant fabrics and post-treatment flame-retardant fabrics. However, the flame-retardant fabrics produced by using these two processing methods have little difference in flame-retardant properties.
What is width
Width refers to the effective width of the woven or knitted fabric in the zonal direction, generally used in inches or centimeters, common 36 inches, 44 inches, 56-60 inches, etc., respectively, referred to as narrow, medium and wide The width of the fabric, which is higher than 60 inches, is an extra width, which is often called a wide cloth. The width of an extra wide fabric in China can reach 360 centimeters.
Why does the width of cotton FR fabric become smaller
According to the different proportions of cotton-containing flame-retardant fabrics, it can be divided into cotton flame-retardant fabrics, C/N flame-retardant fabrics and CVC flame-retardant fabrics, and aramid flame-retardant fabrics, which are aramid flame-retardant fabric synthetic fabrics. A kind of natural flame-retardant fabric with the advantages of heat resistance, high strength, high wear resistance, good flexibility, low shrinkage, chemical structure stability, no droplets of combustion, no gas generation, etc., and the shrinkage rate of different materials after washing It will also be different. So what is the main factor affecting fabric shrinkage? To find out why this widening is smaller, we need to look for the flame retardant pretreatment process. So, let's review the basic processing steps of flame-retardant fabrics. They are "dyeing out - scouring - bleaching - mercerizing - dyeing - flame retardant processing - tentering - pre-shrinking". The last two steps in the procedure are the key steps to ensure the stability of the fabric washing.
Then the problem is in the last few steps. Here we first explain the concept of mercerizing. Mercer is the process of stabilizing the fabric structure, so there will be a width after the mercerizing, but the width of the fabric will increase after the tentering. The step of stenting is not able to meet water. Once it encounters water, it will return to the width of the mercerizing stage, and pre-shrinking is the last step to solve this problem. However, many small workshops and informal manufacturers sometimes save the last step in order to save costs. The width of the fabric is measured according to the width of the tenter, so that the fact that the width of the fabric after the washing is changed will be ignored. When choosing a flame-retardant fabric, it is the right way to choose a guaranteed company. Xinxiang Weis Textiles&Garments Co., Ltd. is undoubtedly your best choice.
