The present invention relates to an ink applying method for obtaining desired sharp patterns while preventing bleeding and an ink composition therefor, in applying a low viscosity liquid to a polymer product such as fabric in the form of droplets according to the ink jet or spray process. As a treating solution there is used a solution incorporating a water-soluble or water-dispersible material which contains --OSO.sub.3 M group or --SO.sub.3 M group as a hydrophilic group in which M is a monovalent metal, ammonium or amine, and a fiber structure is pretreated with a chemical for coagulating the said hydrophilic group, whereby good bleeding preventing effect and deep shading effect even against markedly bleeding fiber structures such as thin fabrics as well as level dyeing effect of colored portions can be attained without impairing the injection characteristic. Sharp patterns equal or superior to conventional prints can be obtained.

Fabric treating method to give sharp colored patterns

Artificial leather and a dyeing method therefor; the leather includes ultrafine polyamide fibers and is particularly a grained artificial leather having bright, deep color, good color fastness to dry cleaning with charged soap, a delicate touch free from any undesirable rubber-like feeling, as well as high durability. A super-entangled fiber base is provided comprising ultrafine polyamide fibers and/or bundles thereof; polyurethane including polyoxyethylene of molecular weight of 500-5,000 is applied. The polyamide ultrafine fibers are dyed with a metal-dye complex and a fixing agent.

Pile fabric having excellent softness and high tear strength which has short fibers planted and adhered to a base with an adhesive, is obtained by applying an adhesive and planting the short fibers to the base, drying or curing the adhesive, and removing at least 5 weight % of the fibers of the base.

Pile fabric production process

A process for treating a fibrous structure is provided. The fibrous structure comprises at least two components at least one of which is a polyester containing an SO.sub.3 M group wherein M represents hydrogen or an alkali metal. The process is characterized in that the fibrous structure is treated with an agent which deteriorates the polyester prior to the alkali treatment for the removal of the polyester component.
