Benefits of technology

[0018]There are many advantages to the present invention. In particular, the present invention, the colored denim of the present invention is sharp, crisp and smooth and the color of the denim of the present invention is natural and brilliant. The denim using the coloring technique of this invention has higher quality (e.g. higher contrast, with washing effects, great hand feel, etc) as compared to denim prepared from conventional coloring techniques such as tainting and garment dyeing with. Further, this technique is environmentally friendly and safe with the use of less water and in absence of the use of resin. Application of this technique leads to more cost-efficient productivity, shorter lead time, and great savings in the overall garment process. Furthermore, the novelties of the present invention are listed as follow:

Embodiment Construction

[0031]As used herein and in the claims, “comprising” means including the following elements but not excluding others.

[0032]Now referring to FIG. 1, FIG. 2 and FIG. 3, the present invention, in one aspect is, a denim comprising a plurality of wrap threads 20 and a plurality of weft threads. Each of the wrap threads 20 further comprises a first yarn 22 and a dye coating that is disposed on the first yarn 22, in which the dye coating comprises a plurality of different dyes. At least one of the plurality of dyes in the dye coating (i.e. first dye 24) at least partially reveals and only partially covers another different dye immediately there-below (i.e. second dye 26); and the bottom most dye (i.e. second dye 26) only partially covers the first yarn 22, such that the dyes (i.e. both first dye 24 and second dye 26) are not disposed on at least a portion of the first yarn 22, thereby showing the wrap thread with a plurality of colors. Each weft thread only consists of a second yarn withou...

Abstract

Slasher machines and rope dyeing machines are the main dyeing machine that is used to continuously dye yarn fabrics for denim using indigo dyes. In denim dyeing, indigo (blue color VAT) and some sulfur dyes are mixed together to achieve blue / black / brown color denim fabrics. This invention is the achievement of dyeing reactive / direct / pigment / acid / disperse and other non VAT / sulfur OR its combinations of non VAT / sulfur dyes OR combinations between VAT / sulfur dyes and VAT / sulfur dyes on continuous yarn dyeing machines and relevant apparatus. Its products are also very distinguishable, especially its combinations, hence is a part of the invention.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the priority of U.S. Provisional Application No. 61 / 820,716 filed May 8, 2013, the whole of which is hereby incorporated by reference herein.FIELD OF INVENTION[0002]The present invention relates to a multi-colored yarns and a fabric made of the multi-colored yarns.BACKGROUND OF INVENTION[0003]Denim is a fabric in which the indigo dyed wrap threads are woven with white weft threads. Many techniques have been developed to color demin, for example, piece color coating, tainting / overdyeing and garment dye, etc. However, these coloring techniques cannot give natural and brilliant colors to denim. As a result, there is a need for a new technique for coloring denim which is also environmental friendly.SUMMARY OF INVENTION[0004]In the light of the foregoing background, it is an object of the present invention to provide an alternative and novel technique in coloring denim (also applies to other fabrics) while preserving th...
