HERCOSETT 125 Synthetic Resin for the Textile Industry

HERCULES, INC. HERCOSETT 125 Synthetic Resin for the Textile Industry  

HERCOSETT 1 25 is a cationic, fiber-reactive, aqueous solution of a polyamide-epichlorohydrin resin. It is used by the textile industry for preventing felting shrinkage of wool, improving abrasion resistance of natural fibers, and as an antistat for synthetic fibers. 

HERCOSETT 125 provides a means of utilizing a highly effective, completely aqueous system for preventing felting shrinkage of wool. The process involves pretreatment of the wool with aqueous chlorine at low pH, followed by neutralization and application of HERCOSETT 125. This process can be used to treat wool sliver continuously, or fabrics and piece goods by a batch process. 

Standard suction drum backwash equipment, having perforated drums with positive liquor recycle, is required for continuous treatment of worsted sliver. Protection of felting shrinkage by batch treatment can be carried out successfully in standard side paddle or overhead paddle dyeing equipment. 

HERCOSETT 125 increases tensile strength, elongation, modulus, and abrasion resistance of wool. It also reduces the strength loss and abrasion loss that result when cotton is finished for crease resistance. When applied alone or in conjunction with a hydroxylic cationic monomer, HERCOSETT 125 is an effective antistat for synthetic fibers (see U.S. Patent 3,382,096).
