Laser-Enhanced Fabric for Digital Finishing by Laser

A fabric has enhanced response characteristics for laser finishing. The fabric can be denim for denim apparel such as jeans. Software and lasers are used to finish apparel made of the fabric to produce a desired wear or distressing pattern or other design. The fabric allows for relatively fast color change in response to the laser, color changes in hue from indigo blue to white, many grayscale levels, and maintains strength and stretch properties. A method used to make the fabric includes spinning, dyeing, and weaving yarns in such a way to obtain the desired enhanced response characteristics for laser finishing.

11674262 · 2023-06-13 · ·

Methods are directed to the use of a supercritical fluid for performing a dyeing of a material such that dye from a first material is used to dye a second material. A supercritical fluid is passed through a first material in a pressurized vessel. The supercritical fluid transports the dye from the first material to at least a second material causing a dye profile of the second material to change as a result of dye from the first material perfusing the second material.

09797089 · 2017-10-24 · ·

A method for photocatalytic white discharge printing for achieving patterns on textiles includes closely integrating substrates with patterned printing plates or fixing patterned printing plates on one or both sides of a substrate, placing them in a reactor equipped with a light source and containing the photocatalytic white discharging formulation. The method has the characteristics of a simple process, short processing, easy controlling and wide adaptability. The process eliminates the need for printing plates and expensive printing apparatus used in complicated conventional printing methods. Additionally, the photocatalytic solution can be reused which avoids generous application of chemical agents and waste discharges that are present in conventional printing methods. The method is beneficial for cutting costs, saving energy, reducing emissions and has cleaner production.

Photocatalytic method of discharge printing for producing colorful patterns on previously dyed textiles
09797090 · 2017-10-24 · ·

A photocatalytic method of colored discharge printing for producing colorized patterns on textiles includes over dyeing textiles with illuminant dyes and ground shade dyes respectively, manufacturing patterned printing plates with hollow-out decorative patterns, applying a photocatalyst on the over-dyed textiles through the hollow-outs, using a photocatalytic method of colored discharge printing to produce localized discoloration of the ground shade while leaving the illuminant dyes on the textile which produces an effect of colorized patterns on the textiles. The method has the characteristics of being a simple process with a simple apparatus and has short processing, easy control and wide adaptability. The method eliminates the needs for printing pastes and expensive printing apparatus used in the complicated process in a conventional printing method.
