Abstract
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.
Claims20
A system comprising:
- a laser-enhanced garment template comprising a denim fabric of cotton yarn dyed using an indigo dye to have a cross section comprising an outer ring and an inner core, wherein a cross section of a ring-dyed yarn comprises a total ring-dye thickness of the outer ring that is from 15 percent to 25 percent of a total thickness of the yarn, and the outer ring is indigo colored due to being penetrated through by the indigo dye while the inner core is white or off-white colored due to not being penetrated to by the indigo dye;
- and
- a digital design tool, creating a finishing pattern to be burned onto the laser-enhanced garment template by a laser finishing machine, wherein the digital design tool generates a visualization in color on a computer screen of the finishing pattern on the laser-enhanced garment template after a postlaser wash and allows editing of the finishing pattern, and
- the editing allowed comprises at least one of altering the finishing pattern itself, altering a position of the finishing pattern relative to the laser-enhanced garment template on the computer screen, or altering a scaling of the finishing pattern relative to the laser-enhanced garment template on the computer screen.
A method comprising:
- providing a laser-enhanced garment made from fabric panels of a denim material, wherein the fabric panels are sewn together using thread,
- the denim material will be finished by using a laser according to a laser input file comprising a digital finishing pattern to remove selected amounts of material from a surface of the denim material at selected locations of the laser-enhanced garment,
- the denim material comprises an indigo ring-dyed cotton yarn having a cross section comprising an outer ring and an inner core, a cross-sectional profile comprises a total ring dye thickness of the outer ring that is from 15 percent to 25 percent of a total thickness of the yarn,
- the outer ring is indigo colored due to being penetrated through by an indigo dye while the inner core is white or off-white colored due to not being penetrated to by the indigo dye, and
- using a digital design tool, creating the digital finishing pattern to be burned onto the laser-enhanced garment by a laser, wherein the digital design tool generates a visualization in color on a computer screen of the finishing pattern on the laser-enhanced garment and allows editing of the finishing pattern, and
- the editing allowed comprises at least one of altering the finishing pattern itself, altering a position of the finishing pattern relative to the laser-enhanced garment on the computer screen, or altering a scaling of the finishing pattern relative to the laser-enhanced garment on the computer screen.
A system comprising:
- a laser-enhanced jeans template comprising a denim fabric of cotton yarn dyed using an indigo dye to have a cross section comprising an outer ring and an inner core, wherein a cross section of a ring-dyed yarn comprises a total ring-dye thickness of the outer ring that is from 15 percent to 25 percent of a total thickness of the yarn, and the outer ring is indigo colored due to being penetrated through by the indigo dye while the inner core is white or off-white colored due to not being penetrated to by the indigo dye;
- and
- a digital design tool, creating a finishing pattern to be burned onto the laser-enhanced jeans template by a laser finishing machine, wherein the digital design tool generates a visualization in color on a computer screen of the finishing pattern on the laser-enhanced jeans template after a postlaser wash and allows editing of the finishing pattern, and
- the editing allowed comprises at least one of altering the finishing pattern itself, altering a position of the finishing pattern relative to the laser-enhanced jeans template on the computer screen, or altering a scaling of the finishing pattern relative to the laser-enhanced jeans template on the computer screen.
