Knitted Fabric Preheating and Setting Tunnel Furnace
Category：Tunnel Oven Production Line
Introduction
The knitted fabric preheating and setting tunnel furnace is a continuous thermal processing equipment specially developed for knitted fabrics.The equipment uses precisely controlled high-temperature airflow to uniformly heat the fabric after width adjustment, eliminating residual stress inside the fibers.It can effectively prevent knitted fabrics from developing edge curling, deformation, and dimensional instability during subsequent processing. It is a key equipment for modern textile dyeing and finishing enterprises to improve product competitiveness.
Applications
Stress Elimination:
Smooths and stabilizes the internal fiber structure of knitted fabrics.
Dimensional Stability:
Controls fabric shrinkage rate to prevent deformation.
Edge Curling Prevention:
Solves the problem of edge curling in open-width knitted fabrics.
Baking and Color Fixing:
Used for functional finishing agent baking and fabric setting processes.
