DIFFERENT TYPES OF SINGEING PROBLEMS , CAUSES AND THEIR SOLUTION:-
Different types of Singeing Problems, Causes and their Solutions:-
Singeing is the process of burning of the fiber hairs projecting through the fabric surface. It is done to obtain a uniform and smooth fabric surface by removing hairiness. To ensure uniform optical reflectance throughout the fabric surface in subsequent fabric wet processing.
The natural fabrics are usually singed in grey form as there can be burned ashes and some sort of yellowing on the fabric which are cleared in the subsequent processes. On the other hand, synthetic fibers and their blends are to be singed after dyeing, otherwise molten amorphous beads take up more dyes making dark spots. Polyester melts at higher temperature and requires a powerful flame.
There are Various Methods of Singeing:-
1) Plate Singeing Machine,
2) Rotary cylinder or roller singeing machine,
3) Gas singeing machine.
The singeing is carried out in yarn or fabric form. In this article I will discuss different types of singeing problems, causes and their solutions.
