    Abstract: PURPOSE:To simplify a complicate image-forming process comprising an ink-jet printing and a specific thermal transfer dyeing of a cloth and enable quick delivery of the printed cloth by carrying out the latter half of the above process in completely dry state using a sheet-formed dye absorbent. CONSTITUTION:A letter, image or identification mark is temporarily formed on a polyester fiber cloth such as woven, knit or nonwoven fabric by an ink-jet process or a special thermal transfer method using an ink composed mainly of a disperse dye, etc., having a sublimation temperature of 180-300 deg.C (preferably 200-250 deg.C) and high sublimation fastness. A sheet-formed dye-absorbent composed of a polyester or polyolefin film is placed on the above cloth and the laminate is heat-treated to effect the dyeing of the cloth-constituting fiber with the dye. The latter half process comprising the heat-treatment and the removal of excess dye in the conventional ink-jet dyeing and thermal transfer dyeing can be performed in dry state in one step.

    Abstract: PURPOSE:To produce an ultra-fine fiber suitable for obtaining dense ultra-fine fiber woven and knit fabric having soft and puffy handle and capable of readily removing a sea component. CONSTITUTION:The ultra-fine fiber is produced by dissolving and/or degrading and removing a sea component using a sea-island type conjugate fiber formed from an island component mainly consisting of two or more kinds of ultra-fine fiber components of 0.3-0.001 denier and a sea component consisting of at least copolyester component composed of sodium sulfoisophthalate/terephthalate to make the fiber ultra-fine.

    Abstract: PURPOSE:To obtain the subject fiber resistant to heat and chemicals, having high knot strength by oxidizing highly oriented polyphenylene sulfide fibers having specific structure using an organic peracid. CONSTITUTION:Polyphenylene sulfide fibers of >=20Angstrom crystal size and >=60% orientation degree pref. comprising ultrafine fibers is first produced by high- speed spinning at >=4000m/min of a polymer composed of structural unit of formula I. The fibers is then put to oxidation treatment using an organic peracid (pref. peracetic acid) to convert the structural unit to a new structural unit of formula II, thus obtaining the objective polyphenylene sulfone fibers comprising ultrafine fibers of >=20Angstrom crystal size and >=60% orientation degree. The fibers is highly resistant to heat and chemicals such as concentrated sulfuric or nitric acid and also rich in flexibility, and can be suitably used for filters, etc., in sectors being required for heat and chemical resistances.

    Abstract: PURPOSE:To provide a concrete form improved in strength, bending strength and heat insulating properties and excellent in the adhesiveness to concrete and a concrete casting method. CONSTITUTION:At least one surface of a foamed object composed of a synthetic resin is reinforced by cloth composed of a composite fiber and/or composite yarn constituted of an adhesive component and a reinforcing component holding high strength. The cloth and at least one surface of the foamed object are integrally bonded through the adhesive component of the composite fiber and/or composite yarn and a resin having properties bonded to concrete is held to the interior and surface of the cloth to constitute a concrete form. Concrete is cast using this form.

    Abstract: PURPOSE:To record e.g. printed images of good fastness on fabric by tentatively forming printed images on a fibrous sheet with a heat-sensitive transfer ribbon for a colorant consisting mainly of dye followed by setting the dye on the fibers through heating. CONSTITUTION:Firstly, printed images like characters, figures or identification marks are tentatively formed on a fibrous sheet with a heat-sensitive transfer ribbon for a colorant consisting mainly of dye. The dye forming the tentative images is then set on the fibers comprising the sheet by heating, thus accomplishing recording images, etc., resistant to washing or friction, etc.

    Abstract: PURPOSE:To ensure a satisfactory reading property in a bar code in a limited area by recording the bar code and a character, picture, identification mark or the like by overlapping them. CONSTITUTION:A character, picture, identification mark or the like is recorded in a part where the main bar code is recorded in a color which doesn't substantially affect the reading property of an optical reader which reads the bar code. At this time, the character, picture, or identification mark are recorded by overlapping them. Moreover, the main bar code is recorded in black or blue, and the character, picture, or identification mark or the like is recorded in red or yellow. Paper, dishcloth polymer film or the like is used for the recording carrier. The dishcloth is textiles, knitting, non-woven cloth constituted of a natural fiber such as silk or cotton, synthetic fiber of a polyester system, polyamide system, or polyacrylonitrile system, regenerative fiber of a cellulose type or protein system, and semi-synthetic fiber or the like.
