Deposición de impureza sólida en el lavado de tejidos de algodón suavizado con esterquat: influencia de los copolímeros acrílico/maléico

Francisco Javier Carrión Fité, Raúl Ricardo Díaz Contreras

Resum


This paper aims to show the influence of the acrylic acid - maleic acid (sodium salt) copolymers on deposition during washing of solid impurities, such as carbon black on cotton materials with and without use of softener. These polymers were studied under variations of their molecular weight and percentage proportional weight in the chain. The softeners used were compounds of the esterquat type. The surfactants used in washing were blends of sodium dodecylbenzene sulphonate and etoxilated alcohols with 6, 8, 10 and 20 m. OE.
