Dying still in supercritical CO2 dyeing device

Abstract

This invention discloses a dyeing kettle of the over-critical carbon-dioxide dyeing device, which is to use for the dyeing of the textile, including arranging the barrel and the sealed convex shoulder flat that is on the upper part of the barrel; the center opening of the barrel's bottom connects with the first connector, the inside center opening of barrel connects with the inner barrel by the support cell; the wall of the inner barrel is arranged with the filter hole uniformly, the upper of the inner barrel connects with the second cover; the barrel wall opening of the barrel's upper connects with the second connector; the under part of the barrel connects with the nip cover, which has the ring space with the barrel, and the upper of the ring space is sealed in the protruding stage that outside the barrel, and the first cover is sealed in the under part, one side of the ring space's under part opening connects with the first adapter, and the other side of upper part opening connects with the second adapter. This invention realizes the combining of the technology of the textile internal dyeing and external dyeing, and the dynamic dyeing in the over-critical dyeing method.

Description

technical field [0001] The invention relates to a dyeing device in the field of textile dyeing, more specifically, to a container used in a supercritical carbon dioxide dyeing device for placing dyed fabrics and reacting dyes and fabrics under specific conditions to achieve dyeing. Background technique [0002] In recent years, countries all over the world are devoting themselves to the research of anhydrous dyeing technology. With the rapid development of modern science and technology, supercritical fluid technology is increasingly valued by many countries in the world, and is gradually applied to many industries such as chemical industry, biology, medicine, environmental protection, cosmetics, hygiene, food, printing and dyeing, and new materials. [0003] A Chinese invention patent (patent application number 200510047767.0) applied by Dalian Institute of Light Industry discloses a supercritical carbon dioxide dyeing device. In this dyeing device, the supercritical carbon ...
