Résumé : |
Over the fast 25 years the demand for consistent leather dyeing has been growing. Consistency in shade from batch to batch, within a batch and across a single hide has become a must for quality assurance and a necessity for quality finishing. The demands of fashion have also Brown so that tanneries have to cover many more colours at one rime in their production.
In the early 1980s, some chemical companies introduced special liquid dyes for drum dyeing. These ranges offered certain advantages to tanners and have increased in use. The dyes are usually from a selected chemical clans, have similar and compatible dyeing properties, and some, enable a vide range of colours to be produced from a small product range.
This means economic benefits to the leather manufacturer, who is able to reduce the inventory of dyes, whilst covering most of the needs of his customer.
Other advantages offered by liquid dyes included the convenience of handling, transport in containers, and less exposure by the workforce to air borne dye particles. The residual content of dye in 'empty' containers was also avoided with all of these points making high contributions towards die Control of Substances Hazardous to Health (COSHH). |
