Study of the effects of dryer machine on knit fabric properties

Abstract

Dryer machine is a very important machine in textile finishing process. Dryer machine is commonly used in textile finishing sector because of having many advantages such as drying the fabric & controlling of fabric GSM, width, shrinkage, spirality and shade variation. Drying process is a mechanical process which is done by the dryer machine. It was very important to observe the effects of drying on knit fabric properties. The project title was hereby designed as “Effect of Dryer Machine on the knit fabric properties”. We have selected nine different knit fabric samples including single jersey, terry fleece, Lacoste, (1x1) rib, pique, stripe, interlock and collar fabric those were used in this research work. The aim of our work was to assess the effects of drying machine on knitted fabric properties. GSM and WPI, CPI, SL of those knit fabrics were calculated before and after drying and the effects have been observed. By this work it has been seen that after drying the fabric GSM is decreased because the fabric comes from squeezer machine and here the fabric carry some water and to dry the fabric by dryer machine the GSM decreased after drying. But some of the fabric WPI, CPI, & SL are increased after drying. The process of changing these parameters is related with the machine speed, temperature and overfeed (%) and that were studied very carefully.
