Migration of Crosslinking Reagents in Cotton/Terene Blended Fabric During Resin Finishing
1985
Pandey, S.N. | Raje, C.R.
The migration of a crosslinking reagent during resin finishing of cotton/terene blended fabric is reported using different softeners (a non-ionic polyethylene emulsion and an anionic sulfonated compound) and in the absence of a softener. The cross linking treatment was done with dimethyloldihydroxy-ethyleneurea. Resin finished fabrics were dried for varying periods (0-60 minutes) at 70°C and were analyzed for moisture content and nitrogen content, from which the percent of water evaporation and of agent migration could be calculated. The data analysis showed an increase in the rate of water evaporation in the beginning, followed by a gradual decrease thereafter, both with and without softeners. The percent of agent migration increased gradually during the initial drying period for the fabric treated with a polyethylene emulsion softener or an anionic sulfonated compound softener or without any softener, followed by a gradual decrease thereafter in the first two cases. The samples treated without softeners exhibited higher agent migration than those treated with softeners. The re lationship between the percent of water evaporation and the agent migration is dis cussed.
