Abstract

The invention belongs to the carpet yarn processing technical field, concretely relates to a preparation method of a permanent antistatic flame retardation multicolor polypropylene bulked filament. The method of the invention comprises the following steps: a), preparing antistatic flame retardation master batches: adding 5%-11% of high-molecular nonionic antistatic agent, 0.6%-1.5% of anionic surfactant and 0.5-1% of alkoxy hindered amine fire retardant in a high speed mixer, performing high speed dispersing and mixing, and heating to the temperature of 110 DEG C to obtain the antistatic flame retardation master batch; and b), spinning, by using a triple screw BCF spinning machine set, taking polypropylene fiber slices, antistatic flame retardation master batches, flame retardation master batches and color master batches as raw materials to prepare the permanent antistatic flame retardation multicolor polypropylene bulked filament. The quality index satisfies the carpet weaving and using requirements, the limit oxygen index is between 28-33, and the rate of the volume to the resistance is less than or equal to 1*1010ohm.cm.

Description

technical field

[0001] The invention belongs to the technical field of carpet yarn processing, and in particular relates to a method for preparing permanent antistatic and flame-retardant multicolor polypropylene bulked filaments. Background technique

[0002] Polypropylene bulked filament can be used in the production of carpets, car blankets, decorative cloths, sealing tops, etc., but it is mainly used in the carpet and car blanket industries. Compared with other conventional chemical fibers, polypropylene fiber has outstanding advantages, such as environmental protection and economy: the cheapest and easy to obtain, the lowest energy consumption and the lowest cost in the production and processing process, and the waste can be directly recycled, the three wastes and environmental pollution are the smallest; high coverage Resistance: Due to the smallest density, it has the strongest covering ability when used as a carpet veil, which is 19% larger than nylon and 33% larger t...
