Embodiment Construction

[0061]The method of the present invention will be described below with reference to FIGS. 1-5 in sequence. According to the method of the invention, first, the pre-washing stage is carried out by feeding the yarn F forward from the delivery roller, on which the yarn will pass through the pre-washing device 1, which includes two or several Liquid 10, 15 for tank 2. The yarn is led by rollers 3 and 4 into a first tank 2 containing a pre-wash liquor, then, on leaving this wash liquor, the yarn passes between two squeeze rollers to remove excess liquor and then passes through the rollers 6, the yarn is again immersed in the pre-wash solution. On leaving the bath, the yarn passes between two squeeze rollers 7 . Guided by guide rollers 8 and 9 , the yarn is then dipped into the prewash liquor 15 contained in the second tank 2 . The yarn is conveyed through the second groove by a sequence of operations between the two squeeze rollers 12, between the guide roller 11 and then betwee...

Abstract

A method for dyeing textile material using indigo with the help of 3-indole-oxyl includes such steps as passing yarn through pre-washing unit, passing the yarn through 9 serially communicated tanks containing 3-indde-oxyl solution for dyeing, passing the yarn through the washing and pre-drying unit composed of a series of tanks, passing the yarn through sizing unit for sizing it with indigo dye, passing the yarn through dryer containing rollers, and winding yarn to obtain warp yarn.

Description

technical field [0001] The present invention relates to a method for dyeing textile materials by means of indigo using 3-indoxyl groups, and to an apparatus using the method. [0002] By means of this method, indigo-dyed textile yarns are produced from which so-called denim fabrics can subsequently be produced for the production of articles such as blue jeans. Background technique [0003] Indigo is one of the oldest known dyes and has been used for centuries to dye textiles such as cotton. [0004] EP-B-0692042 describes a process for the dyeing of cellulose-containing textiles with indigo, in which leuco (colorless) indigo prepared by catalytic hydrogenation is used, after its absorption into the textile After exposure, it will be converted to its pigmented form by air oxidation. [0005] US-A-4283198 describes a continuous process for dyeing cellulosic fibers with indigo in which the fibers are passed through a series of dipping tanks containing a dyebath comprising: le...
