The following specification particularly describes the invention and the manner in which it is to be performed

ENVIRONMENTALLY SUSTAINABLE DENIM GARMENTS
BACKGROUND
[0001] The present invention relates generally to fabric treatments and more particularly to a process for minimizing the use of water while making denim garments.
[0002] The fashion industry is one of the most impactful industry worldwide in terms of consumption. However, it is also one of the foremost contributors of water pollution (approx. 1 trillion gallons). It is understood that the fashion industry contributes to about t 20% of the global water pollution.
[0003] Jeans or the denim garments, is an indispensable part of almost every person’s wardrobe. However, in order to produce the denim garments with the pre-washed look, the untreated garment goes through several chemical-heavy washes. Further, the printing and dyeing of the denim fabric involves the use of heavy metals like cadmium, Sulphur, lead and mercury. These by-products from washing with such metals, along with the blue dye which is used on a large scale (i.e. 2.5 million pairs of jeans a day) is often released into nearby water resources.
[0004] Further garment washing releases indigo dyes along with harsh chemicals used for washing which contaminates the nearby waterbody if effluent treatment is not done properly. The impact is huge considering present day denim garment washing in large scale across the world. The untreated water waste renders the waterbodies inhabitable for aquatic life.
[0005] Thus, there is a need for a process where denim fabrics are manufactured using more sustainable methods.

[0014] The present invention provides process of making a less water denim garments which eliminates the preproduction activity, shrinkage checking, pattern making and garment washing thereby no effluent treatment is required, no water pollution and environmental bad effect.
[0015] FIG. 1 schematically illustrates the process 100 of the present invention in which a less water denim fabric is prepared, where the garment washing process has been eliminated without effecting look and feel of the product. In one embodiment, the raw denim fabric is de-sized and mercerized in order to make the fabric ready for laser printing. Each step of the process in described in further detail below.
[0016] At step 110, the process forms at least one pattern on the fabric by using a laser to mark one or more patterns on the fabric. In one embodiment, each pattern represents one or more characteristics. In one embodiment, the patterns are marked by using the laser to change the denim fabric in a way that changes the physical appearance of the fabric. Examples of the patterns include combination of whiskers, Chevron, brushing effect at thigh, back knee, coin pocket, back yoke, high low effect of seams and outline, etc. In one embodiment, the actual pattern which is used for fabric cutting is incorporated in the laser program by uploading the pattern file in computer, with the outline of actual marker. It may be noted that the patterns are characterized by their corresponding parameters and by the fabric image.
[0017] At step 120, the process washes the printed fabric to remove one or more laser burn marks. In an embodiment, the fabric is taken for a wash to remove ashes generated on fabric surface and to give good handle of the fabric.
[0018] At step 130, t the printed fabric is treated with a resin mixture in order to provide dimensional stability and to control the shrinkage of the fabric. Further, the treatment also provides similar shade and look which is identical for a specific style. In one embodiment, the resin mixture comprises dimethylol dihydroxy ethylene urea, polysiloxane and water. The amount of dimethylol dihydroxy ethylene urea in the resin mixture is in the range of 60 -80 gram/liter, the amount of polysiloxane in the resin mixture is in the range of 30-40 gram/liter, and the amount of water in the resin mixture is in the range of 880-910 ml.
[0019] At step 140, the denim fabric is dried and subsequently cured at a temperature ranging from about 1500 C of about 5 minutes of dwell time. The fabric can then be cut as per predefined markers on the fabric and stitched all the parts to produce a ready to wear garment. Since the finished garment does not have to go through several rounds of washing, thus conserving water thus eliminating the need of effluent treatments that lead to water pollution. The product followed by the above-mentioned process will be cheaper by 15-20% as compared to the current processes. It is also noted that the time required to produce the garment is significantly reduced by about 50%.
