摘要:
A composite textured yarn contains a component yarn A and a component yarn B each false twisted and crimped. The component yarn B is shorter in yarn length or larger in shrinkage at least after heat treatment. Single fibers of component B have thick portions and thin portions successively alternating in the longitudinal direction.

A method of recycling an image-deposited recording material having a surface portion which swells in contact with water and bears thereon deposited images containing an image-constituting material, include the steps of: (a) applying a water-containing image removal promoting liquid to the image-deposited surface portion of the recording material, (b) bringing an image release member into contact with the image-deposited surface portion of the recording material to transfer the images to the image release member to remove the images from the image-deposited recording material, and (c) applying heat to the image-deposited recording material at least after the step (a), with substantially retaining the water component of the image removal promoting liquid in the image-deposited surface portion. In addition, there is disclosed an apparatus for recycling the above-mentioned image-deposited recording material comprising an image removal promoting liquid application means, a water evaporation preventing means, a heat-application means for heating the image-deposited recording material in such a manner that the water component of the image removal promoting liquid is retained in the surface portion, and an image release means.

摘要:
A recording method by use of an ink is disclosed, in which images are formed by an aqueous ink comprising at least one dye selected from the group consisting of a pyrazolone azo dye, a phthalocyanine sulfonate dye, a xanthene dye and an azo dye on a recording medium containing at least one component selected from the group consisting of a water-soluble metal salt whose metal has an ion valence of 2 or more, an alkyl amine and a quaternary ammonium salt.
摘要:
An image removing method including heating a recording material having thereon an image to a temperature so that the image has a plasticity; pressure-contacting an uppermost stream peeling member with the recording material while the image maintains a plasticity; separating the uppermost stream peeling member from the recording material to transfer at least a portion of the image to the uppermost stream peeling member; and repeating the heating, pressure-contacting and separating steps at least one more time using at least one downstream peeling member, wherein the uppermost stream peeling member has a first outermost layer which does not have a plasticity when being pressure-contacted with the recording material, and at least one of the at least one downstream peeling member has a second outermost layer which has a plasticity when being pressure-contacted with the recording material.
摘要:
A disclosed image formation apparatus includes: a manual paper feed unit supplying a recording material; an image formation unit receiving the recording material from the manual paper feed unit; an image removal device removing an image recorded on the recording material; an installation unit detachably installing the image removal device on the image formation apparatus; and a switching unit switching whether the recording material fed from the manual paper feed unit is supplied to the image removal device installed using the installation unit or to the image formation unit.
摘要:
A method for reusing a recording medium forms an image on the recording medium by use of an image forming material, and removes the image forming material from the recording medium through thermal transfer by use of a peeling member. The recording medium is paper produced by applying a treatment liquid at a size pressing after paper making and then drying the treatment liquid. The treatment liquid includes a water-soluble or water-dispersible polymer having an alkyl group with carbon atoms at its side chain as an image-repellant substance. The image forming material includes a thermoplastic resin, and the adhesive strength between the peeling member and the image forming material is higher than the adhesive strength between the recording medium and the image forming material.
