Embodiment Construction

[0017] The structural representation of the dyeing still in the supercritical carbon dioxide dyeing device of the present invention as shown in Fig. 2 The process of dyeing in contact with textiles. The structure of the dyeing kettle includes a material cylinder 17 with a closed bottom and a shouldered flat cover 16 arranged on the top of the cylinder 17. The shouldered flat cover 16 can be disassembled and needs to be fixed and sealed during work. The top of the shoulder flat cover 16 is threadedly connected to the threaded sleeve 18, and the threaded sleeve 18 is threaded to the upper part of the cylinder body 17, and the upper end of the threaded sleeve 18 is fixed with a positioning nut 19; An O-ring 15 is provided. Wherein, the threaded sleeve 18 acts as a fixed shoulder flat cover 16 and achieves multi-layer sealing through the O-ring 15 . Because in the supercritical carbon dioxide dyeing process, higher pressure is required, so the sealing performance in the dyeing k...

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 ...
