Method and machine for treating textile materials by ammonia or other liquids

Abstract

The machine comprises: a path for the textile article (T); along the path impregnation means (11, 13) to impregnate the textile article with said product; means (23, 25) to remove the product from said textile article. The impregnation means may comprise one or more cooled rollers (11, 13) on which the product condenses and around which the textile article to be treated is driven.

Description

TECHNICAL FIELD

[0001] The present invention relates to a method for treating textile materials by ammonia, in particular bolts of fabric or yarns. This type of method is commonly known as mercerization. More generally, the invention relates to a method for treating textile articles or materials by liquids at low condensation temperature.

[0002] The invention also relates to a machine for treating textile materials. STATE OF THE ART

[0003] Mercerization is a typical treatment for fabrics and yarns made of all cellulosic fibers, particular for cotton, which allows the material to be given a series of advantages, such as:

[0004] increase in luster and hydrophilicity,

[0005] increased dimensional stability,

[0006] increased yield of the dye,

[0007] an improvement and intensification of subsequent finishing treatments (i.e. anti-crease treatments).

[0008] Currently, the mercerization process is performed with the use of alkalies, generally caustic soda, which determines:

[0009] shrinkag...
