Range of Finishing Agents

The KAURIT types are either free or etherified N-methylol compounds of urea or of melamine. They are used mainly for the resin finishing of regenerated cellulose fibres, alone and in blends with synthetics. The term self-crosslinking agents characterizes their mode of reaction. 

The KAURIT types improve the crease-recovery and dimensional stability of cellulosic textiles. They reduce the swelling capacity of these textiles and produce permanent calender and plisse effects. 

Finally, the KAURIT types are also used for finishing special types of synthetic textiles. A typical example is the stiff finishing of polyamide and polyester fabrics. 

KAURIT S is a urea-formaldehyde compound its composition is roughly that of dimethylol urea. The product is supplied in the form of white, fine powder with almost 100% active substance. 

KAURIT S reacts under mild curing conditions, mainly with formation of crosslinkages with itself, and it imparts good crease-recovery and a firm and resilient handle to the goods.

Electrical Behavior. The resistivity of acetate varies significantly with humidity with typical values ranging from 10 ohm-cm at 45% rh to 10 ohm-cm at 95% rh (16). Because of the high resistivity both acetate and triacetate yams readily develop static charges and an antistatic finish is usually apphed to aid in fiber processing. Both yams have also been used for electrical insulation after lubricants and other finishing agents are removed.
