色付繊維を紡糸する装置および方法
Document Type and Number:
Japanese Patent JP2006514715
Kind Code:
A
Abstract:
An apparatus and a method for spinning dyed filaments from a dyed polymer melt, wherein an undyed polymer melt is produced by a melt producer. A liquid dye is added to the polymer melt by means of a dye metering device. To mix the liquid dye and dye the polymer melt, a mixing unit is provided. The dyed polymer is then spun to filaments by means of a spin unit. To obtain before the spinning step a uniform coloration of the polymer melt despite the short dwelling time of the liquid dye in the polymer melt, the liquid dye and the polymer melt are mixed in a plurality of successive mixing units which are formed by a mixer combination comprising at least one static mixer and at least one dynamic mixer.
