<p>A process for modifying fibrous materials, especially keratinous and cellulosic materials is provided. Polythiols which are polymers based on polybutadiene or poly(methylbutadiene), containing, on average, more than one thiol group per molecule, directly attached to carbon atoms of the polymer are used optionally in combination with an aminoplast. The polymers cure on the fiber. Keratinous materials are rendered resistant to shrinkage and durable press characteristics are imparted. Cellulosic fibers are rendered crease-resistant and durable press characteristic may be imparted too.</p> |
