Abstract
Method for developing potential yarn bulk in knitted fabric by introducing the fabric into a turbulent flow of heated air.
Claims8
A process for developing yarn bulk in a knitted fabric article comprising yarn having potential bulk which is compatible with the time required to knit the article, said process comprising agitating and tumbling the fabric article in a chamber, directly after knitting in an automatic integrated process therewith and before said article is subjected to any wet treatment, by a turbulent stream of upwardly flowing heated air introduced into the chamber so as to support the fabric therein and removing the fabric in crease-free condition from the chamber after a period of time sufficient to develop the bulk.
