Abstract
A method for improving the colourfastness of a dyed textile is provided. The method comprises the steps of: conveying the dyed textile along an automated processing line and into a first chamber having a first controllable environment; temporarily storing the dyed textile in the first chamber for a first time period; conveying the dyed textile into a second chamber having a second controllable environment; and temporarily storing the dyed textile in the second chamber for a second time period.
Claims30
A method for improving the colourfastness of a dyed textile, the method comprising:
- conveying the dyed textile along an automated processing line and into a first chamber having a first controllable environment;
- temporarily storing the dyed textile in the first chamber for a first time period;
- conveying the dyed textile into a second chamber having a second controllable environment;
- and
- temporarily storing the dyed textile in the second chamber for a second time period.
The method according to any preceding claim, wherein the first internal temperature is between 140° C. and 230° C.
The method according to any preceding claim, wherein the second internal temperature is between 120° C. and 200° C.
The method according to any preceding claim, wherein the second time period is greater than the first time period.
The method according to any preceding claim, wherein the first time period is at least 10 minutes.
The method according to any preceding claim, wherein the second time period is at least 2 hours.
The method according to any preceding claim, further comprising:
- determining a cool down rate for the dyed textile, and
- adjusting the controllable environment of the first and/or second chamber based on the cool down rate.
The method according to any preceding claim, further comprising:
- temporarily storing the dyed textile at a plurality of different temperatures in the second chamber.
The method according to any preceding claim, further comprising:
- conveying the dyed textile through a plurality of different temperatures within the second chamber.
The method according to any preceding claim, further comprising:
- consolidating the dyed textile into a roll within the first chamber.
The method according to any preceding claim, further comprising:
- conveying the dyed textile through a fixation chamber having a third controllable environment.
The method according to any preceding claim, further comprising:
- transporting the second chamber to a new location whilst the dyed textile is temporarily stored therein.
The method according to any preceding claim, further comprising:
- applying a dyestuff comprising a colourless dispersant to an undyed textile.
The method according to any preceding claim, further comprising:
- dispensing dyestuff onto the textile via an array of flow channel dispensers.
Apparatus for improving the colourfastness of a dyed textile, the apparatus comprising:
- a processing line configured to convey dyed textile into a first chamber having a first controllable environment, wherein the first chamber is configured to temporarily store the dyed textile for a first time period;
- and
- a second chamber having a second controllable environment, wherein the second chamber is configured to temporarily store the dyed textile for a second time period.
