Provided is a temperature sensor film comprising a metal-thin film patterned on a resin film substrate, and having high temperature measurement accuracy. A conductive film () that is used for producing a temperature sensor film has a nickel thin film () on one principal surface of a resin film substrate (). It is preferable that the interplanar spacing of nickel (111) plane in the nickel thin-film is less than 0.2040 nm. The temperature sensor film is obtained by patterning the nickel thin film to form a temperature-measuring resistance part and a lead part connected to the temperature-measuring resistance part.

Temperature sensor film, conductive film and method for producing same

An electroconductive film () comprises a metal thin-film () on a first main surface of a flexible substrate () that includes a resin film (). The thickness of the flexible substrate is 1 mm or less. The absolute value |H−H| of the difference between the heating dimensional change rate Hof the electroconductive film and the heating dimensional change rate Hof a film obtained by removing the metal thin-film from the electroconductive film is preferably 0.10% or less. There is a tendency that undulation of a temperature sensor film after patterning of the metal thin-film is further suppressed as the value of |H−H| decreases.

An object of the invention is to provide a cloth having water absorbency, water repellency, and a tendency to float on water, and also a textile product using the cloth. A means of resolution is to obtain a cloth using a fiber A that is not water repellent and a fiber B that is water repellent in a weight ratio (fiber A:fiber B) within a range of 50:50 to 87:13.

Cloth and textile product

A conjugate fiber-containing yarn containing side-by-side or eccentric core-in-sheath conjugate fibers each composed of a polyester component and a polyamide component, that can be crimped by heating, and that has properties of increasing its crimp ratio when it absorbs moisture or water and is excellent in windbreaking and warmth-retaining properties, has a wool-like soft and bulky hand, and is capable of forming a fabric in which a see-through property is not increased even when wetted with water.

Conjugate fiber-containing yarn

A woven or knitted fabric, formed from two types of yarns different in self-elongating property upon absorbing water and capable of facilitating the air-permeability when wetted with water, is constituted so that a ratio A/B of a mean length A of yarns () having a high water-absorbing, self-elongating property to a mean length B of yarns () arranged in the same direction as that of the yarn () and having a lower water-absorbing, self-elongating property than that of the yarn () is adjusted to 0.9 or less.

Woven or knitted fabric containing two different yarns and clothing comprising the same

A composite fiber is described which comprises a polyester component and a polyamide component bound in a side-by-side or eccentric core-in-sheath structure, exhibiting a percentage of crimp DC of 1.3-15.0% after the composite fiber is treated in boiling water for 30 minutes under a load of 1.76&#xd7;10cN/dtex, and then dry heat treated for 30 minutes at 100&#xb0; C. under a load of 1.76&#xd7;10cN/dtex, for stabilization of the crimps and further dry heat treated for one minute at 160&#xb0; C. under a load of 1.76&#xd7;10cN/dtex, as well as a percentage of crimp HC of 0.5-10% after immersion in water at 20-30&#xb0; C. for 10 hours, and a difference &#x394;C of 0.5-7.0% between the percentage of crimps.
