[0026] Example 2 Alcoholysis Separation of Waste Polyester-Cotton Textiles
[0027] 1. Raw materials:
[0028] Alcoholysis agent: ethylene glycol;
[0029] Catalyst: sodium carbonate;
[0030] Waste polyester-cotton blended fabric: polyester 87 / cotton 13 (only waste polyester-cotton tops with fusible interlining and metal attachments removed);
[0031] The weight ratio of the alcoholysis agent to the waste polyester-cotton blended fabric is 6:1;
[0032] The amount of catalyst added is 0.4‰ of the weight of waste polyester-cotton blended fabric.
[0033] 2. Use the device described in Example 1 to carry out alcoholysis separation, and the specific steps are as follows:
[0034] I. Put the waste polyester-cotton blended fabric into the inner cylinder, add the alcoholysis agent and catalyst into the outer cylinder through the feed port, and close the cylinder cover;
[0035] II. Turn on the motor and heating device, so that the inner cylinder rotates forward and reverse, an...

Abstract
The invention relates to a device for separating components of waste polyester-cotton blended fabric. The device is a horizontal rotary alcoholysis separation device and consists of an outer barrel and an inner barrel; the outer barrel is connected with a vacuum reflux condensing device; heating elements and a heat insulation layer are arranged at the periphery of the barrel wall of the outer barrel; the inner barrel is horizontally arranged in the outer barrel along the axial direction; through holes or meshes are formed in the barrel wall of the inner barrel; the inner barrel is provided with a vacuum/micro-pressure dual-purpose mechanical seal rotating shaft, and the rotating shaft passes through the outer barrel and is connected with a motor; the rotating shaft is driven by the motor, so that the rotating action of the inner barrel can be realized in a micro-pressure or vacuum state; the tail end of the vacuum reflux condensing device is connected with a collecting tank; the collecting tank is connected with a vacuum apparatus. When the device is used for carrying out alcoholysis on the waste polyester-cotton blended fabric, the process of stirring is omitted, so that the problem of property damage caused by winding of rest cotton yarns during stirring can be solved; the problems that an alcoholysis agent is left over in the rest cotton yarns, discharge is difficult to realize, and the like are solved; therefore, after the device is adopted, the components of the waste polyester-cotton blended fabric are efficiently and conveniently separated and recovered.
Description
technical field [0001] The invention relates to a component separation device for polyester-cotton blended fabrics, in particular to a component separation device for polyester-cotton blended fabrics in a horizontal centrifugal alcoholysis kettle. Background technique [0002] my country is a large textile country, with a stock of waste textiles of 26 million tons per year, including 18 million tons of chemical fibers (12 million tons of polyester), and 8 million tons of natural fibers. Polyester is divided into pure polyester, polyester cotton, polyester and other blends. , while the proportion of polyester-cotton in polyester is as high as about 70%, that is, the stock is as high as 8.4 million tons / year. However, due to the difficulty in recycling polyester-cotton blended fabrics, most of them have not been effectively recycled, resulting in a huge amount of waste textiles , not only pollute the environment, occupy a large amount of storage space, but also cause a great was...
