Problems solved by technology

[0012] Another problem is that it is difficult to control the degree of fiber removal from fabrics during known finishing methods; conventional friction-based methods always significantly reduce the mechanical integrity of fabrics, thus reducing the tensile strength of treated fabrics and garments

Embodiment approach

[0098] According to an exemplary embodiment, the first weft yarn of the woven fabric has 118,2tex (5 / 1Ne) to 5,91tex (100 / 1Ne), preferably 19,7tex (30 / 1Ne) to 8,44tex (70 / 1Ne), More preferred is a defined density of 13,13 tex (45 / 1 Ne) to 10,754 tex (55 / 1 Ne); even more preferred, the first weft yarn has a linear density of 11,82 tex (50 / 1 Ne).

[0099] In a preferred embodiment, the linear density of the first weft yarn of the woven fabric ranges from 24,625 tex (24 / 1Ne) to over 11,82 tex (50 / 1Ne), or ranges from 49,25 tex (12 / 1Ne) to 14 , 775tex (40 / 1Ne), or the range is 73,875tex (8 / 1Ne) to 19,7tex (30 / 1Ne), or the range is 118,2tex (5 / 1Ne) to 24,625tex (24 / 1Ne).

[0100] According to an exemplary embodiment, the count or linear density range of the second weft yarn is 118,2tex (5 / 1Ne) to 5,91tex (100 / 1Ne), preferably 19,7tex (30 / 1Ne) to 8,44tex (70 / 1Ne), more preferably 13,13tex (45 / 1Ne) to 10,754tex (55 / 1Ne); even more preferably, the linear density of the second weft y...

Embodiment 1

[0165] Example 1 - Production of Fabric A.

[0166] according to Figure 9 The Weaving Report produces woven fabrics with the following characteristics:

[0167] Warp: 73,875tex (Ne 8 / 1) ring spun slub cotton

[0168] Weft 1: 84,43tex (Ne 7 / 1) ring spun cotton

[0169] Weft 2: 11, 82tex (Ne 50 / 1) combed cotton

[0170] Warp density: 29.5 threads / cm

[0171] Weft density: 42.0 picks / cm

Embodiment 2

[0173] Comparative Example 2 - Treatment with Pumice

[0174] A sample of the fabric of Example 1, measuring 30 cm x 20 cm, was subjected to the following stone:liquor ratio: 1:10, 150 g of pumice for 1 kg of fabric, at 30° C. for 15 minutes. The results are shown in Figure 8 The sample 4.

Abstract

Provided is a process for the production of a dyed fabric using enzyme aggregates. In particular, provided is a process that comprises a step of providing a woven fabric that comprises a base layer and an additional layer which is located on at least one side of the fabric, wherein the yarns of the additional layer comprise fibers that are at least partially dyed, and a step of contacting the woven fabric with enzyme aggregates such as cross-linked enzyme aggregates (CLEAs), to remove at least part of the dye from at least the yarns of said additional layer. The disclosure also provides a fabric obtained with the process and garments including the fabric.

Description

technical field [0001] The present invention relates to a method of producing a woven fabric having a worn appearance, a fabric obtained by said method and a garment comprising said fabric. In particular, the present invention relates to methods of producing fabrics and articles comprising fabrics having a "worn" or "worn" appearance. The method uses enzyme aggregates, preferably cross-linked enzyme aggregates (CLEA). Background technique [0002] Frayed fabrics, especially denim, have become popular in the fashion industry, particularly due to the different appearances that can be applied to fabrics and thus have different visible effects on the front of the fabric (i.e., when wearing an article made of the fabric Visible surface) finishing process. In fact, success in the denim industry relies heavily on the creativity that comes from various fabric finishing methods that give fabrics a unique look and feel. [0003] Fabrics, as well as the exterior appearance of articl...
