Abstract

The invention discloses equipment and a process for preparing a low-melting-point chinlon hot melt yarn. The process comprises the steps: putting polyamide slices into a heating extruder; pressing, melting, homogenizing and the like by a screw extrusion process to obtain a melt; and after being pressurized by the pressurizing device, the melt is filtered by a filter box. The problems of high meltviscosity and low filtering speed are solved; the filtered melt enters a heat preservation box to be subjected to heat preservation and is pressed out through a spinning assembly and a spinneret plateto form trickles and is cooled into filaments under cross air blowing and is subjected to drafting and heat setting through a first hot roller and a second hot roller and then is wound through a winding device to obtain the low-melting-point chinlon hot melt yarn, and the strength of the low-melting-point chinlon hot melt yarn is improved. The equipment and the process for preparing the low-melting-point chinlon hot melt yarn are reasonable in structure and convenient to use and can effectively solve the problem of low strength of the low-melting-point chinlon hot melt yarn.

Description

technical field [0001] The invention relates to the technical field of nylon hot-melt yarn preparation, in particular to equipment and a process for preparing low-melting-point nylon hot-melt yarn. Background technique [0002] In the known technology, low-melting point polyamide fiber is a high-grade adhesive material, and it is a relatively excellent thermal adhesive in thermal bonding fibers. It does not soften below the melting point, and has excellent oil resistance, wear resistance and solvent resistance. The Chinese patent number is ZL201410623473.7, and the patent name is a low-melting point thermally bonded polyamide fiber filament and its preparation method. The raw material adopts the one-step process of FDY spinning, drawing, and shaping, and the fiber filaments are obtained by spinning, drawing, and shaping through three pairs of hot rollers at different temperatures. However, this method also has the following disadvantages: the low-melting point nylon therma...
