Abstract

The invention relates to a diversified BCF (bulked continuous filament) spinning machine which can produce Dacron PET (polyethylene terephthalate), nylon PA (polyamide) and PP (polypropylene). The diversified BCF spinning machine comprises a dacron BCF continuous spinning machine, electric heating wires are uniformly arranged in a first drafting roller and a second drafting roller of the Dacron BCF continuous spinning machine, the first drafting roller is at the temperature of 70-90 DEG C, the second drafting roller is at the temperature of 120-180 DEG C, drafting multiple of the first drafting roller and an input roller ranges from 3.8 to 4.2, and drafting multiple of the second drafting roller and the input roller ranges from 2.7 to 3.3. The diversified BCF spinning machine has the advantages that the Dacron BCF continuous spinning machine can produce three kinds of yarns and production cost is greatly saved.
