In a winch dyeing, the fabric remains in movement while the dye liquor stays stationary similar to a jigger but with lesser stress on the materials. Hence, suitable for delicate textures and fabric types such as knitted fabrics.
A jet mill grinds materials by using a high speed jet of compressed air or inert gas to impact particles into each other. [1] Jet mills can be designed to output particles below a certain size while continuing to mill particles above that size, resulting in a narrow size distribution of the resulting product. [ 2 ]
The pump laser can be seen entering the dye jet, beneath the yellow window. A dye laser is a laser that uses an organic dye as the lasing medium , usually as a liquid solution . Compared to gases and most solid state lasing media, a dye can usually be used for a much wider range of wavelengths , often spanning 50 to 100 nanometers or more.
