Technical Field

[0001] The utility model relates to the technical field of yarns, in particular to a flame-retardant yarn. Background Art

[0002] Yarn is a textile made of various textile fibers and processed into a certain fineness. It is used for weaving, rope making, thread making, knitting and embroidery. Flame-retardant yarn is a specially made yarn with good high temperature resistance and can prevent the spread of combustion. Flame-retardant yarn is widely used in the textile industry in places with high fire risks, such as aviation, automobiles and construction.

[0003] Chinese utility model patent CN215976220U discloses a multifunctional and efficient flame-retardant yarn structure, including a flame-retardant bobbin, the surface of which is provided with a yarn body, the yarn body including a core layer, the surface of which is wrapped with a heat-insulating layer, and the surface of which is wrapped with a flame-retardant layer. The utility model provides a wear-resistant layer so that the surface of the yarn body has a certain wear resistance, thereby preventing the flame-retardant layer on the yarn body from being worn due to friction when washing clothes made of the yarn body, thereby reducing the flame-retardant effect of the yarn body. At the same time, an indicator layer is provided on the wear-resistant layer, and the indicator layer is made of a coating with a different color from the wear-resistant layer. When the indicator layer is exposed, the color of the yarn body changes through the indicator layer, and the user can judge whether the wear-resistant layer is completely worn by observing the color of the yarn body.
