Abstract
The present study deals with the reactions of dimethylolurea
and dimethyloldihydroxy ethylene urea (ARK NO) with
standard cotton cellulose under various drying conditions, padbath
pH, curing temperatures, swelling agents, deposited polymers
and added eleotrolyte.
It has been found that:
(a) Drying at room temperature and at 105oC produce
fabrics with identical crease recovery angles but the resin
add-on is higher with fabric dried at higher temperature.
(b) Curing at 140oC for 6 minutes is as effective as
curing at 1600C for 3 minutes using HC1 catalyst,
(c) Compared with magnesium chloride and zinc chloride,
sodium hydroxide preswelling produces fabrics with higher
crease recovery angles and moisture regain.
(d) Where pad-bath pH is high, the efficiency of the
latent acid catalyst is impaired.
(e) Fabrics treated in 10% sodium hydroxide have fairly
good tensile strength, crease recovery angles, and moisture
regain.
(f) Added electrolyte in the pad-bath facilitates
high resin add-on,
(g) Polymer deposition produces fabrics of low moisture
regain but high recovery angles.
