A kind of high-strength flame-retardant protective yarn and its preparation method

Abstract

The invention discloses high-strength flame-retardant protection yarn which comprises a yarn body. The yarn body is provided with a long filament reinforcing layer, a fiber thermal insulating layer and a fiber protecting layer from inside to outside in sequence. Through the high-efficiency flame-retardant performance of the fiber protecting layer, the flame-retardant effect is greatly improved; through the excellent thermal insulating performance of the fiber thermal insulating layer, the yarn has an outstanding protecting effect; through the high-strength performance of the long filament reinforcing layer, the brute force of the yarn is remarkably improved. In addition, the fiber protecting layer has good moisture absorption performance, and the good wearing comfort level of a fabric woven from the yarn is ensured; the yarn is easy to dye, and the colors of the yarn, the fabric and clothes are enriched; the fiber protecting layer has good radiation resistant performance, and the radiation resistance performance of the yarn is stable.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a high-strength flame-retardant protective yarn. Background technique [0002] At present, the domestic yarns with flame retardant function mainly make the yarns have flame retardant function by performing flame retardant treatment on the yarn, but there are some problems in the use of this kind of flame retardant yarn: 1. The yarn will produce fire when it encounters fire. Toxic smoke and dust have harmful effects on human health and the environment; 2. The treated flame-retardant yarn is not resistant to washing, and the flame-retardant effect is greatly reduced after washing, so it cannot be used for a long time; 3. The yarn has low strength and cannot meet special purposes Therefore, the demand for high-efficiency flame-retardant, non-toxic and environmentally friendly, high-strength and durable flame-retardant protective yarns is increasing day by day.
