Definitions

  • Shaped articles consisting of polyrolefines cannot be dyed satisfactorily by direct application of dyes by the normal techniques employed in the dyeing art.
  • a process for the treatment of shaped articles containing or consisting of polyolefines to increase their 'afiinity for dyes which comprises treating the said articles first in an acid bath containing an alkali metal bichromate and the in an acid bath containing a reducing agent, the temperature of each bath being at least 80 C.
  • the temperat-ure of the bath containing the bichromate should preferably not exceed 105 C.
  • this temperature should preferably not exceed 120 C.
  • the hexavalent chromium is reduced to trivalent chromium, which then fixed in the material.
  • the process of the invention makes it possible to improve the afiinity for dyes of all textile articles consisting of polyolefines, such as filaments, fibres, continuous filament and staple fibre yarns, tows, mono-filaments, cables or woven fabrics, as also of other shaped articles, as well as for non-textile articles such as films, sheets and profiled articles generally.
  • the first treatment bath preferably contains at least 25 .g./litre of the alkali metal b-ichrornate. It may be made acid by means of any strong acid, sulphuric acid or hydrochloric acid being preferred.
  • the duration of the first treatment may vary (eg from 5 to 30 minutes, and may even be prolonged for several hours without damage to the article to be treated.
  • the second acid treatment bath preferably contains up to 50 g./litre of a su-lphite or of another strong reducing agent, such as sodium formaldehyde sulphoxylate. Higher concentrations may be employed if desired.
  • Example I Various samples of polyethylene yam of high density (0.95) are treated at 100 C. for varying times in a bath containing, per litre:
  • the filaments are thereafter treated for one hour in a second bath at C. containing 5 cc. per litre of a sodium bisulphite solution (36 B.),
  • the various yarn specimens contain the following quantities of fixed trivalent chromium.
  • Example [I A jersey manufactured of high-density (0.96) polyethylene yarns is treated for half an hour in a. first bath as in Example I.
  • the chromium content is 0.157%.
  • Example I]! A woven fabric formed of continuous polypropylene ylarns is treated for one hour at 100 C. in a bath containing, per litre:
  • the fabric After rinsing, the fabric is treated for 1 /2 hours at C. in a bath containing, per litre:
  • Example IV A woven fabric consisting of polyethylene yarns (the polyethylene having been produced by high pressune polymerisation) is treated at 105 C. in a pressure-resistant stainless steel apparatus for minutes, in a bath containing, per litre:
  • the fabric is wrung out and treated for one hour in a second bath at 98 C. containing g./litre of sodium formaldehyde sulphoxylate.
  • the fabric is dyed without difficulty in one hour at 98 C. with the basic dye Orange Astrazon R (Colour 'IndeX No. 48040).
  • the fabric is dyed with a fine, very bright orange hue.
  • a process for the treatment of shaped aliphatic polyolefine articles to increase their affinity for dyes comprising contacting the said shaped articles first with a bath containing, per litre, to 55 grams of alkali metal bichromate and 100-250 cc. of concentrated sulphuric acid, for 5 to 120 minutes, and then with an acid bath containing a reducing agent, the temperature of each bath being at least 80 C.
  • a process for the treatment of filamentary aliphatic polyolefine material to increase its afiinity for dyes which comprises contacting the said filamentary material first with a bath containing, per litre, 25 to 55 grams of alkali metal bichromate and 100-250 cc. of concentrated sulphuric acid, for 5 to 120 minutes, and then with an acid bath containing a reducing agent, the temperature of each bath being at least 80 C.
  • a process for the treatment of filamentary aliphatic polyolefine material to increase its affinity for dyes which comprises contacting the said filamentary material first with a bath containing, per litre, 25 to 55 grams of alkali 4.- metal bichromate and 100-250 cc. of concentrated sulphuric acid, for 5 to 120 minutes, and then with an acid bath containing a sulphite reducing agent, the temperature of each bath being at least 80 C.
  • a process for the treatment of filamentary aliphatic polyolefine material to increase its atfinity for dyes which comprises contacting the said filamentary material first with a bath containing, per litre, 25 to grams of alkali metal bichromate and 100-250 cc. of concentrated sulphuric acid, for 5 to 120 minutes, and then with an acid bath containing sodium formaldehyde sulphoxylate, the temperature of each bath being at least C.
  • a process for the treatment of filamentary aliphatic polyolefine material to increase its affinity for dyes which comprises contacting the said filamentary material first with a bath containing, per litre, 25 to 55 grams of alkali metal bichromate and -250 cc. of concentrated sulphuric acid, for 5 to minutes, and then with an acid bath containing a reducing agent, the temperature of each bath being 80 to 120 C.
  • a process of the treatment of filamentary aliphatic polyolefine material to increase its afiinity for dyes which comprises contacting the said filamentary material first with a bath containing, per litre, 25 to 55 grams of alkali metal bichr-omate and 100-250 cc. of concentrated sulphuric acid, for 5 to 120 minutes, and then with a hydrochloric acid bath containing up to 50 g./litre of a sulphite, the temperature of each bath being at least 80 C.
  • a process for the treatment of filamentary aliphatic polyolefine material to increase its affinity for dyes which comprises cont-acting the said filamentary material first with a bath containing, per litre, 25 to 55 grams of alkali metal bichromate and 100-250 cc. of concentrated sulphuric acid, for 5 to 120 minutes, and then with a hydrochloric acid bath containing up to 50 g/litre of sodium formaldehyde sulphoxylate, the temperature of each bath being at least 80 C.
