Abstract

The invention relates to a permanent antistatic flame-retardant polyamide-6 bulked continuous filament textured carpet yarn and a preparation method. The permanent antistatic flame-retardant polyamide-6 bulked continuous filament textured carpet yarn comprises a carpet yarn body, wherein the carpet yarn body consists of two tows of flame-retardant polyamide-6 bulked continuous filaments in different colors or the same color and a tow of antistatic polyamide-6 bulked continuous filaments; single fibers in the three tows of polyamide-6 bulked continuous filaments are random three-dimensional crimped fibers; different types of fibers are randomly mixed and intertwined; and periodical net knots are arranged on the surface of the carpet yarn body. The preparation method is implemented by one step through a tri-screw bulked continuous filament (BCF) spinning machine set. The product substantially maintains the characteristics of abrasion resistance, stain resistance, resilience and the like of polyamide-6, and also has a permanent antistatic function and a flame-retardant function. According to the preparation method, the characteristics of a production process of the tri-screw BCF spinning machine set are utilized, so that the aim of spinning the antistatic flame-retardant polyamide-6 textured carpet yarn by one step is fulfilled, and the production process is simple, practical and efficient.

Description

technical field [0001] The invention belongs to the technical field of carpet yarn processing, and in particular relates to a permanent antistatic and flame-retardant nylon 6 bulked filament color carpet yarn and a preparation method. Background technique [0002] Carpet is a flooring material for interior decoration with a long history. It can not only beautify the environment, relieve pressure, and make people feel comfortable, but also has the functions of heat preservation, air dust absorption, noise reduction and sound absorption, etc. It is widely used all over the world. . According to statistics, the sales of European and American fiber flooring materials account for about 70% of the total consumption of flooring materials, while other hard flooring materials such as ceramic tiles and floors only account for about 30%. Since the machine-made carpet replaced the traditional handmade carpet production method in our country in the early 1980s, it has been widely used i...
