MOVABLE DYEING CONTAINER FOR SUPERCRITICAL FLUID WATERLESS DYEING

WIPO Patent Application WO/2017/201768

A1

The invention discloses a movable dyeing container for supercritical fluid waterless dyeing, replacing a conventional fixed supercritical fluid sample dyeing unit with a movable dyeing container, and achieving the goals of filling a medium into a plurality of dyeing units (dyeing containers) separately or simultaneously, and then increasing temperature and performing a sample dyeing process on all dyeing units together. A medium outlet (10) is disposed at a lowest part of a round container bottom. Polytetrafluoroethylene (PTFE) is coated on the entire inner surface of the dyeing container, effectively reducing dyes attaching to the inner wall and edges of the dyeing container, and increasing cleaning efficiency. A porous blocking plate (7) at the round container bottom effectively prevents blockage of a textile product at the medium outlet (10) at the dyeing container bottom during filling or exhausting a medium, thereby successfully discharging, via the medium outlet (10), the processing medium and remaining dyes. The invention can overcome the shortcomings of conventional fixed supercritical fluid sample dyeing devices and matching systems, including a low utilization rate, difficult cleaning, and inability to satisfy sample dyeing requirements in commercial production.
