Problems solved by technology

[0025] However, it is difficult for most producers of denim fabrics to combine this new technology with traditional indigo dyeing techniques
This is not only because of the considerable financial commitment and the large space required, but also because of the difficulties that arise in the production management of the two different technologies

Embodiment Construction

[0052] Referring to the accompanying drawings, there is shown a multifunctional continuous dyeing device for yarn chains according to the invention, which is generally indicated by the reference numeral 10 . In particular, device 10 is configured to dye ropes or flat warp strands for fabrics, and device 10 is designed to use both indigo and other dyes.

[0053] The dyeing device 10 is provided with a main body 12 at the bottom. With reference to the feed direction F of the yarn 100, the following treatment groups consisting of such yarns 100 are successively obtained in the main body 12:

[0054] - at least one first dyeing group 14 for dyeing a yarn 100, the first dyeing group 14 being provided with a corresponding first pressing device 16 for pressing such a yarn 100; and

[0055] - Oxidation or diffusion / fixation group 18, which is placed downstream of the first dyeing group 14 and which is configured for: dyeing in the case of dyeing in air or to diffuse / fix the dye in t...

Abstract

A multifunctional continuous dyeing apparatus for a yarn is described. The dyeing apparatus is provided at the bottom with a main body (12) within which are formed in a sequence, with reference to thefeeding direction of the yarn, at least a first dyeing group (14) for the yarn (100), provided with a respective first squeezing device (16) of the yarn, an oxidation or diffusion / fixation group (18), placed downstream of the first dyeing group (14) and arranged for the oxidation of the dyed yarn or for the diffusion / fixation of the dye in the fibre of said dyed yarn, and at least a second dyeinggroup (20) of the yarn, arranged downstream of the oxidation or diffusion / fixation group (18) and in turn provided with a respective second squeezing device (22) of the yarn. At least the first dyeing group (14), the first squeezing device (16), the oxidation or diffusion / fixation group (18) and the second dyeing group (20) are hermetically sealing enclosed by at least one covering case (24), integral at the top with the main body (12), and provided with a plurality of doors (26) which are at least partially openable to perform the dyeing of the yarn in an environment exposed to air and whichare reclosable to perform the dyeing of the yarn in an inert environment under nitrogen.

Description

technical field [0001] The present invention relates generally to an apparatus for continuous dyeing of warp strands for fabrics, and in particular to a treatment method and multifunctional dyeing apparatus utilizing indigo and / or other dyes, wherein denim fabrics The yarn strands of the warp are continuously subjected to indigo and / or other dyes. More specifically, the present invention relates to a treatment method using a reducing bath and a multifunctional continuous dyeing device. Background technique [0002] A typical application of this device is the continuous dyeing of warp strands for denim fabrics with indigo or other dyes. Denim is the fabric commonly used to make jeans and "sportswear" articles, and is the most used fabric in the world in terms of volume. [0003] The Denim Blue Jeans Alliance owes its success precisely to the dyeing of the warp yarns of this fabric with indigo. Indigo is one of the oldest dyes and is not easily applied to cotton yarn due to...
