Knitted fabrics singeing

As with woven fabrics, hairiness of the face of knitted fabrics is seldom desirable. There are various ways to avoid this problem. The yam quality, uniform face appearance and proper yam count are important factors where the quality of knitted fabric is concerned. The quality can be further improved by additional process stage such as, for instance, singeing. 

The singeing machine for circular knit fabric differs from the well-known singeing machine for woven fabrics only in guiding and transport of the fabric. The real problem consists in properly opening out the tubular fabric. The distance between burner and fabric must be exactly the same at every point. The burner must be so designed that there is an uniform flame intensity over the entire tube circumfer-... 

Conditions for high repellency of finished fabrics inclnde a close-packed textile structnre with small inter-yam spaces (therefore better woven than knitted) with fine yams (preferably microfibres or microfilaments) and a uniform distribution of the repellent finish. This last condition is enhanced by the removal of protmding surface fibres by singeing or shearing. 

There are three methods to remove surface fibres from 100% cotton woven and knit goods, namely singeing in the greige state and bio-polishing. The third method is home laundering the fabrics using detergent that contains a cellulase enzyme.
