Abstract

Purpose

The polymer air-drawing model of spunbonding nonwovens has been established. The influence of the density and the specific heat capacity of polymer melt at constant pressure changing with polymer temperature on the fiber diameter have also been studied. The paper aims to discuss these issues.

Design/methodology/approach

TDMA method is used to solve the difference equations.

Findings

It can be concluded that a lower polymer throughput rate, a higher polymer melt initial temperature, a higher air initial temperature, and a higher air initial velocity can all produce finer fibers.

Originality/value

The results also reveal the great potential for this research in the computer-assisted design of spunbonding technology.
