Dyeing of Sisal and other Plant Fibres: A Handbook for Craft Instructors (NRI)

Appendices

1. Conversion tables

Figure Table A - Acetic acid: relationship between specific gravity and concentration at 15°C

Figure Table B - Formic acid: relationship between specific gravity and concentration 20°C

Figure Table C - Sulphuric acid: relationship between specific gravity, density and concentration

Figure Table D: Volume of liquor required with weights of fibre between 1 kilogram and 5 kilograms to obtain liquor ratios in the range of 10:1 to 50:1

Figure Table E: Weight of additive required with volumes of liquor between 20 litres and 100 litres to obtain concentrations in the range of 1 - 50 9/1

Figure Table F: Weight of dyestuff or additive required with vveights of fibre between 1 kilogram and S kilograms to obtain percentages on weight of fibre in the range of 0.1 - 9.0 per cent

2. Near equivalents of withdrawn dyes

New dyestuffs are continually being introduced to the market whilst others are withdrawn. Consequently some of the materials described are no longer available. However, close equivalents of many withdrawn dyes are available from other manufacturers. These near equivalent dyes have different trade names but share the same Colour Index Generic Name (e.g. Cl Reactive Yellow 22).

In this Appendix sources of dyes with the same Generic Name as the withdrawn dyes mentioned in the handbook are listed: full addresses for the manufacturers are given in Appendix 3.

It is emphasised that none of these near equivalents have been investigated by the Tropical Development and Research Institute and it is not certain that their properties and behaviour are identical to those dyes investigated.

Safety note: Two dyes in Table G are based on the chemical benzidine. This chemical is a suspected carcinogen and its use is now restricted. The actual dyestuffs, although allegedly safe, should be treated with care to ensure that they do not contaminate the person, the atmosphere, or the work area. If they are used, the working area should be washed down frequently and the dyers should wear protective clothing, inclusive of face masks, and wash themselves thoroughly after handling the dyes (see Safety precautions and first aid treatment).

3. Addresses of dyestuff and chemical manufacturers or their agents

Manufacturers of dyestuffs and chemicals are too numerous to be listed here. However, an extensive list of dyestuff manufacturers can be found in Volume 5 of the Colour Index together with trade names of dyes listed by their Colour Index Generic Name (Colour Index Number). Dyestuff manufacturers frequently also offer a range of dyebath assistants and after-treating agents. There are also companies which specialise in making textile processing chemicals. Only companies able to supply those dyes (or their near equivalents) and proprietary chemicals mentioned in this handbook are given. Sources of common chemicals such as salt and soda are not included. Abbreviations used in the text for the names of manufacturers are given before the full name and address.

Mention of a particular company or product does not imply recommendation by the Tropical Development and Research Institute to the exclusion of others.
