The heat retaining clothing of the invention comprising at least one inflatable envelope which is made of a polymer film. The film has a thickness of 50 to 150 .mu.m and an elastic modulus of extension of at least 90%.

Heat retaining clothing

The heat retaining article according to the invention comprises at least one inflatable envelope attached on a sheet material. The envelope is made of an air-impermeable sheet which is produced by treating a cloth with at least one synthetic or natural rubber. The heat retaining property of the article can be controlled by adjusting the amount of air filled in the envelope.

Heat retaining article

The moisture-permeable waterproof fabric according to the invention comprises a polyamino acid modified polyurethane film having a thickness of 2 to 20 microns and a fabric bonded on the polyurethane film by a polyurethane adhesive in an amount of at least 10 g/m.sup.2. The polyamino acid modification ratio of the polyurethane film is within the range of 2 to 20%. The total amount of the adhesive and the polyurethane film is not more than 50 g/m.sup.2.

Moisture-permeable waterproof fabric

Natural suede-like artificial leathers are manufactured by subjecting pile fibrous structures wherein at least the pile portion is composed of separatable composite filaments made by bonding different polymers having mutual low adhesive affinity with each other, the cross-section of which is constituted of a radial segment (A) and segments (B) complementing the radial segment or a radial segment (A), segments (B') corresponding to said radial segment and having wedge-shaped concave portions directing to the center and wedge-shaped segments (C) complementing said concave portions, to at least one of a heat treatment and a swelling treatment to shrink said fibrous structure at least 10% in the area, impregnating or coating said fibrous structures with a synthetic polymer solution or emulsion, coagulating said polymer solution or emulsion, drying the thus treated pile fibrous structure and then buffing said piles to raise naps.

Synthetic fibrous structures having a soft feel, an excellent luster and a silky feel are produced by forming composite filaments composed of a polyamide and a component having poor affinity to the polyamide selected from the group consisting of a polyester, polyolefin and polyacrylonitrile into a fibrous structure and treating the fibrous structure with an aqueous emulsion of 1.5-50% by weight of at least one of benzyl alcohol and phenylethyl alcohol and having a percent transmittancy of less than 20%, which is obtained by adding a surfactant to the emulsion, whereby to fibrillate the composite filaments.
