A waterproof fabric having a high moisture permeability and having an ultra-microporous continuous polymer coating having an average pore diameter in the range of between 50 .ANG. and 0.2.mu., said polymer having a monomer unit containing at least one acid radical selected from carboxyl group, sulfonic acid group, and alkali metal salts thereof.

Waterproof fabric having high moisture permeability and method of making

A fabric containing a cellulosic fiber and a polyester fiber having a carbonization burning mechanism, superior in flame-proofness and having a soft touch. The fabric contains a halogen- and/or phosphorus-based flame-proofing agent, and preferably also contains an amino resin.

Flame-proof fiber product

Inclined artifical fur and method of manufacturing the same

A process for producing modified polyester products by the graft polymerization of vinyl monomers having an acidic group and replacing the acidic group with an alkali metal salt, the replacing being carried out after dyeing. By this process, decrease in strength and color fastness of polyester fibers can be avoided while giving the polyesters characteristics similar to those of cotton.

Modification of polyester products

The production of pile fabric, comprising the use of a compound of two or more azilidine groups or two or more blocked isocyanate groups in one molecule, with a polyurethane solution as a binding agent is disclosed. The binding strength of the binding agent is not affected by high-temperature, high-pressure jet-dyeing or the solvent used in dry-cleaning. There is no loss of quality as a result of pile fall-out during such processes.

Pile fabric production method using polyurethane binding agent

Disclosed is a highly flame-retardant fiber of excellent color-fastness which is made from the mixture composition of 30 to 60 parts of an amino resin composed of a condensation product of formaldehyde with melamine and other amino compounds selected from, urea, dicyandiamide and benzoguanamine, and 70 to 40 parts of polyvinyl alcohol. The incorporation of 0.1 to 4.0% by weight of phosphorus by the addition of a reactive organic phosphorous compound to the spinning dope or to the wet filaments before drawing causes noticeable enhancement of the flame-retardance. Curing and crosslinking may be carried out during the yarn-making process of spinning, drawing and heat-setting or after the yarn-making process by treatment in an acidic formaldehyde environment.
