CTA EC50, a water and oil repellent organic fluorine is used in woolen fabric finishing. The influence of the concentration, curing time and temperature of CTA EC50 and its matching cross linking agent on the finishing result is investigated with optimized parameters obtained.
(2) By choosing the water-proof finishing oil and designing the coordination of oils for the spinning properly, the PP/PE low melting point heat-adhesive core-sheath composite fiber could be endured perfectly durable Water-repellent property.
