Apparatus for processing fiber and yarn by liquid ammonia

Abstract

The invention provides a device for treating fibers and yarns with liquid ammonia, comprising a horizontal pressure tank and a set of rotary sarong mechanism, wherein the rotary sarong mechanism comprises an electric motor arranged at one end of a tank body, a rotating shaft connected with a driving shaft of the electric motor into a whole, a sarong bracket fixedly arranged on the rotating shaft,and a plurality of sarongs movably arranged inside the sarong bracket; the inside at the other end of the tank body is provided with a clapboard, and the front end of the rotating shaft is rotationally arranged on the clapboard. The device is adopted to treat fibers and yarns so that the liquid ammonia content on the fibers and the yarns before washed and dried is greatly reduced, the ammonia content on a hank yarn is reduced by 70 to 85 percent, and the ammonia content on a cone yarn is reduced by 50 to 75 percent. The device is capable of saving energy, shortening the treatment period and greatly lowers the treatment cost. In addition, the device ensures that the fibers and yarns are immersed in ammonia evenly, and solves the problem of dirty marks caused by removing ammonia by drying so that the quality is affected.

Description

technical field [0001] The invention relates to a fiber and yarn processing equipment, in particular to a device for treating fiber and yarn with liquid ammonia. Background technique [0002] In textiles, cellulose fiber fabrics have the advantages of good wearing comfort, good hygroscopicity, and no static electricity, but have problems such as easy wrinkling, shrinkage, and poor dyeing performance; on the contrary, synthetic fiber fabrics have poor wearing comfort. and the generation of static electricity. For the consideration of factors such as wearing comfort and health, people are still willing to wear cellulose fiber fabrics, especially pure cotton fabrics. Therefore, the textile industry has carried out research on the existing problems of cellulose fiber fabrics, and found that after the fabrics are treated with liquid ammonia, or the fibers and yarns are treated with liquid ammonia and then woven into fabrics, the above problems can be solved. However, the fibers...

AI Technical Summary

Problems solved by technology

At present, the pressure tank type liquid ammonia treatment equipment is generally used to process fibers and yarns. This equipment has the advantages of sealing the treatment process, no pollution, and adjustable treatment pressure. However, the liquid ammonia remaining on the fibers and yarns after impregnation More (accounting for more than 100% of the yarn weight), the commonly used washing and drying methods will greatly increase the energy used to recover liquid ammonia, and if it is not recycled, it will cause serious pollution

At the same time, fibers and yarns contain a large amount of ammonia, and direct drying and removal of ammonia will form stains; washing and removal of ammonia will increase the cost of recovering ammonia from ammonia water and the cost of re-drying yarn
