Garment with Finishing Pattern Created by Laser
A garment includes a finishing pattern created by a laser. The garment can be a pair of jeans or other denim garment. Software and lasers are used in finishing apparel to produce a desired wear pattern or other design. A technique includes determining a fabric's response to a laser, capturing an initial image of a wear pattern on a garment, and processing the initial image to obtain a working image in grayscale. The working image is further processed to obtain a difference image by comparing each pixel relative to a dark reference. The difference image is converted to a laser values image by using the previously determined fabric response to the laser.
1 . A garment comprising:
fabric panels made from a woven first material comprising a warp comprising dyed cotton yarn, wherein the fabric panels are sewn together using thread; and
an outer surface of the garment comprises a finishing pattern created by a laser based on a laser input file, wherein the laser input file comprises digital data that is representative of a finishing pattern from an existing garment made from a second material, the first material comprises a different fabric characteristic from the second material, and the laser input file is created by
capturing a target image of the finishing pattern from the existing garment of the second material, and
determining values for the laser input file that will result in a finishing pattern on the first material to obtain an appearance similar to the target image of the finishing pattern from the existing garment of the second material, wherein the determining values for the laser input file comprises
selecting a dark reference in the target image of the finishing pattern from the existing garment of the second material,
for a pixel in the target image, calculating a difference value between a pixel value and the dark reference, and
storing a difference value in the laser input file, wherein the laser input file comprises a reverse image compared to the target image.
2 . The garment of claim 1 wherein the warp is ring dyed using an indigo dye,
based on the laser input file, selected amounts of material have been removed by the laser from the surface of the first material at different pixel locations of the garment, and
for lighter pixel locations of the finishing pattern, a greater amount of the dyed cotton warp yarn is removed, while for darker pixel locations of the finishing pattern, a lesser amount of the dyed cotton warp yarn is removed.
3 . The garment of claim 1 wherein the finishing pattern created can extend across portions of the garment where two or more fabric panels are joined together by thread by exposing these portions to the laser.
4 . The garment of claim 1 wherein the first material comprises a weft comprising yarn that has not been dyed.
5 . The garment of claim 1 wherein for the portions of the garment exposed to the laser where the fabric panels are joined, the fabric panels are joined together using a thread comprising cotton.
6 . The garment of claim 1 wherein the finishing pattern on the outer surface of the garment was created by a single pass of a laser.
7 . The garment of claim 1 wherein the finishing pattern on the outer surface of the garment was created by multiple passes of a laser.
8 . The garment of claim 1 wherein the capturing a target image of the finishing pattern from the existing garment of the second material comprises using contrast limited adaptive histogram equalization image processing.
9 . The garment of claim 1 wherein to create the finishing pattern on the outer surface of the garment, different laser levels are obtained by varying an output of the laser beam by altering a characteristic of the laser comprising at least one of a frequency, period, pulse width, power, duty cycle, or burning speed.
10 . The garment of claim 1 wherein the first material comprises a first surface texture characteristic which is different from a second surface texture characteristic of the second material.
11 . The garment of claim 1 wherein the first material comprises a first dye characteristic which is different from a second dye characteristic of the second material.
12 . The garment of claim 1 wherein the first material comprises a first base fabric color characteristic which is different from a second base fabric color characteristic of the second material.
13 . The garment of claim 1 wherein the first material comprises a first yarn characteristic which is different from a second yarn characteristic of the second material.
14 . The garment of claim 1 wherein the first material comprises a first yarn weight characteristic which is different from a second yarn weight characteristic of the second material.
15 . The garment of claim 1 wherein the first material comprises a first yarn diameter characteristic which is different from a second yarn diameter characteristic of the second material.
16 . The garment of claim 1 wherein the first material comprises a first yarn twist characteristic which is different from a second yarn twist characteristic of the second material.
17 . The garment of claim 1 wherein the finishing pattern on the existing garment was not created by a laser.
18 . The garment of claim 1 wherein the finishing pattern created by the laser on the garment includes a wear pattern comprising at least one of combs or honeycombs, whiskers, stacks, or train tracks, or a combination.
19 . The garment of claim 1 wherein the first material comprises a denim.
20 . The garment of claim 1 wherein the second material comprises a denim.
21 . The garment of claim 1 wherein the first material comprises a cotton twill.
22 . The garment of claim 1 wherein the second material comprises a cotton twill.
23 . The garment of claim 1 wherein the first material comprises a denim, and the second material comprises a denim.
24 . The garment of claim 1 wherein the first material comprises a cotton twill, and the second material comprises a cotton twill.
25 . The garment of claim 1 wherein the garment comprises a pair of pants.
26 . The garment of claim 1 wherein the existing garment comprises a pair of pants.
27 . The garment of claim 1 wherein the garment comprises a pair of jeans.
28 . The garment of claim 1 wherein the existing garment comprises a pair of jeans.
29 . The garment of claim 1 wherein the garment comprises a pair of pants, and the existing garment comprises a pair of pants.
30 . The garment of claim 1 wherein the garment comprises a pair of jeans, and the existing garment comprises a pair of jeans.
