Developments in Textile Continuous Processing Machineries

• Closely singed fabric is essential for printing FME intricate patterns
• The singed fabric can be desized using the fabric surface temperature.
2.3.2 Major Disadvantages of Singeing
• Uneven singeing results in streak marks which appear prominent after dyeing
• Singeing of blended fabrics containing synthetic fibres may result in deposition of
small globules of melted synthetic fibres. This melt absorbs more dye which gives
fabric specky appearance post dyeing
• Temperature sensitive fibres like polyester can get thermally damaged if flame
intensity and distance is not managed properly
• Machine stoppages causes heat bar marks on fabrics
• Heat sensitive sizing agents when exposed to heat results in firmly binding of
sizing agents with fibres which makes desizing difficult
• When singeing operation is done after dyeing, heat in singeing causes colour loss
in case of low sublimation fast dyes
• It may result in loss of tear strength.
