The development of flame retardant yarn and flame retardant filament

At present in the domestic application of flame-retardant fabric products are mainly flame-retardant fabrics, fire-retardant carpet. Flame retardant fabric raw materials are mainly cotton, polyester, wool and so on. Domestic use of flame-retardant fabric products according to the different ways to use the popular saying there are two: pre-treatment and post-processing flame-retardant fabric.
Pre-treated flame-retardant fabric Some domestic manufacturers also claim to be permanent flame retardant fabric. Pretreatment of flame-retardant fabric production process: adding flame retardants, change the molecular structure, to produce flame-retardant polyester chips, flame retardant fiber, and then in accordance with customer requirements to produce flame retardant yarn, and then plain, twill, satin Texture, knitting, weaving and other woven into a knitted fabric, and then by dyeing, printing, embossing and other special technology into a flame retardant fabric. This flame retardant fabric in accordance with the requirements of national regulations to wash more than 30 times still maintain the original flame retardant properties, basically in the end of its use cycle has been to maintain flame retardant performance, so some manufacturers claim to be permanent flame retardant fabric. For technical reasons, the current domestic production of pre-treated flame-retardant fabric is basically based on chemical fiber raw materials flame-retardant fabric.
Post-treated flame-retardant fabric refers to the ordinary fabric production is completed by adding a flame retardant properties of chemical substances soaked or flame retardant coating produced by the flame retardant fabric with flame retardant properties.
Pre-treated flame-retardant fabric is the advantage of soft, color and pattern and ordinary fabric is no different; long life cycle, burning a small amount of white smoke, very little toxic gas, environmentally friendly products. But in the process of domestic promotion also exposed a lot of shortcomings: compared with ordinary fabrics, manufacturers less, so the existing product color and pattern less, to meet the individual needs of customers inconvenience, according to customer orders to the manufacturers Custom, production cycle about two months.
Post-processing of flame-retardant fabric is the advantage of fabric patterns, more types of colors to meet the individual needs of customers. The price is lower than the pre-treated flame retardant fabric. But its shortcomings more obvious, the color dark, sticky, feel more hard, most of the fabric even when used more or less volatile toxic gas; after washing flame retardant performance, such as to maintain flame retardant performance, need Reprocessing. Most of the post-processing flame-retardant fabric in the combustion of more smoke, volatile toxic gases.
