Abstract

The invention discloses a system for producing stepped modularized acrylic filaments, comprising a power device. The system is characterized in that the power device is in driving connection with a plurality of acrylic filament production modules, wherein each acrylic filament production module at least comprises a rotary spinning apparatus, a solvent stretching device, a water washing device, a hot stretching device, a drying device and a coiler device which are arranged sequentially. The system has the advantages of low ground occupation, compact and reasonable structure, simple operation and high degree of automation, thereby effectively reducing the energy and material consumption and realizing the low-cost quantitative production.

Description

technical field [0001] The invention belongs to the technical field of acrylic filament production, and in particular relates to a modularized acrylic filament production line system. Background technique [0002] Acrylic fibers are usually called polyacrylonitrile fibers, but the first monomer of acrylonitrile only accounts for 90% to 94%, the second monomer accounts for 5% to 8%, and the third monomer accounts for 0.3% to 2.0%. Fibers made from a single acrylonitrile polymer lack flexibility, are brittle, and are very difficult to dye. In order to overcome the defects of polyacrylonitrile, people use the method of adding the second monomer to make the fiber soft; adding the third monomer to improve the dyeing ability. Therefore, when the first monomer of acrylonitrile>85%, it is called acrylic fiber. [0003] Acrylic fiber has the following characteristics: acrylic fiber has better elasticity, second only to polyester, and about 2 times higher than nylon. It has good...
