This invention relates to a method of manufacturing a fabric for ink jet printing and to an ink jet printing method for imparting to the fabric a clear and sharp image free from ink oozing in ink jet printing. Specifically, it relates to a method of manufacturing a fabric for ink jet printing which is characterized in that an aqueous treatment solution having a water-insoluble solvent dispersed or emulsified in an aqueous polymer solution is imparted to the fabric and dried; and to an ink jet printing method characterized in that the ink jet printing is made with the ink jet printing fabric used and that after developing, the pretreatment agent is removed by washing the fabric.

Manufacturing method of fabric for ink jet printing and ink jet printing

Method for dyeing a polyamide fabric in a grandrelle tone, and a dyed

A fiber of a polyester, in which 80% or more of the repeating units are composed of ethylene terephthalate, characterized in that it satisfies the following inequalities:

Polyester fiber, process for the production and process for the dyeing

The present invention relates to an ink applying method for obtaining desired sharp patterns while preventing bleeding and an ink composition therefor, in applying a low viscosity liquid to a polymer product such as fabric in the form of droplets according to the ink jet or spray process. As a treating solution there is used a solution incorporating a water-soluble or water-dispersible material which contains --OSO.sub.3 M group or --SO.sub.3 M group as a hydrophilic group in which M is a monovalent metal, ammonium or amine, and a fiber structure is pretreated with a chemical for coagulating the said hydrophilic group, whereby good bleeding preventing effect and deep shading effect even against markedly bleeding fiber structures such as thin fabrics as well as level dyeing effect of colored portions can be attained without impairing the injection characteristic. Sharp patterns equal or superior to conventional prints can be obtained.

Fabric treating method to give sharp colored patterns

Pile fabric having excellent softness and high tear strength which has short fibers planted and adhered to a base with an adhesive, is obtained by applying an adhesive and planting the short fibers to the base, drying or curing the adhesive, and removing at least 5 weight % of the fibers of the base.

Pile fabric production process

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

A fur-like napped fabric and process for manufacturing same are disclosed wherein a fiber layer comprising uncrimped short fibers or short fibers having a number of crimps of not greater than 10 crimps per inch are provided as a fiber layer on a base fabric. The fibers are then implanted into the base fabric by needle punching. Thereafter, the fibers are raised to form a nap. After needle punching, the base fabric and fibers may be bonded to each other by means of a backing treatment or the like which is carefully applied so as not to permeate the raised hair portion extending on the front surface of the fabric. Especially pleasing aesthetic effects are produced when the napped fibers have static frictional coefficients of less than 0.35 and wherein the bending recovery rate of said fibers is higher than 50%.

Fur-like napped fabric and process for manufacturing same

This invention relates to a liquid-retaining synthetic fiber having a substantially pointed free end and including a tapered portion having an acute ridgeline on its surface. It is prepared from a synthetic fiber having in section at least one concave portion and at least one convex portion which gradually taper off toward the outside from the center. These fibers are suitable for use in brushes, or for the manufacture of knitted or woven fabrics or flocked fabrics having an animal hair-like or fur-like touch or appearance.

Liquid retaining synthetic fiber, process for producing the same, and

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.
