Singeing is the process of removal of protruding fibres from the surface of fabric through the application of open flames while the fabric is in motion. The fuel typically used is LPG, with a defined ratio of gas to air. Singeing helps improve the fabric’s appearance and reduces its tendency to form pills; this also helps prevent the surface of the fabric from picking up dirt. The singeing process is performed in the grey stage itself, in order to take advantage of the dry state of the fabric. Also, singed fabric also can be dyed and processed better.
Singeing is a widely accepted process in the woven processing industry. However, in the knit processing industry, singeing is much less common as textile manufacturers have historically worked with tubular knits. Singeing is difficult to perform on fabrics in tubular form as the flame to fabric distance is hard to control accurately, which results in uneven singeing.
in order to impart to tubular knit fabrics the same kind of finish achieved through singeing in woven fabrics, the surface of the knitted fabric is cleaned in a soft flow dyeing machine through biopolishing. In this method, the fabric is treated with aggressive textile auxiliaries. However, biopolishing has several disadvantages:
To address these pain areas, Osthoff Senge – a leading German textile machine manufacturer – has introduced a singeing machine that can singe open width knit fabric. Through innovative German technology, Osthoff’s open width knit singeing machine solves a number of problems faced in tubular singeing machines. Open width singeing not only provides excellent value addition to the finished fabric, but it is also eco-friendly.
Osthoff’s open width knit singeing machine is a proven product. More than 70 open width knit singeing machines are in operation around the world, with more than 40 machines in Turkey, and two machines in operation in India.
While a few open width process houses have been established in India, the industry overall is yet to adopt at scale some of the established practises that are used in knit processing industries around the world. With the pronounced advantages of open width singeing over biopolishing, it is hoped that the industry would switch over to this best practice sooner rather than later.
