Abstract
A method and a fiber-treatment system dry wet or damp fibers. A fiber mat (13) including wet or damp fibers is formed on a treatment band (31) which is moved in a conveying direction (x). An air flow (36, 36a) composed of heated drying air is generated in the fiber dryer (30). The heated drying air is guided in an upward direction through the treatment band and the fibers contained in the fibre mat (13, 14) are loosened and dried. Linters (16) possibly produced by any moving fibers are captured by a filter band (32) arranged above the treatment band, which is also moved in the conveying direction (x). At the outlet of the fiber dryer, the fibers are detached from a support (17) formed on the filter band, in particular when guiding the detached fibers back towards the dried fibers guided to the treatment band (31, 31c).
Claims18
A drying process for drying damp or wet fibers, the drying process comprising:
- forming a fiber mat from wet or damp fibers on a treatment belt, which is moved in a conveying direction through a fiber dryer, which is essentially air-tight towards an outside;
- of generating an air stream in the fiber dryer from a heated drying air, wherein the air stream is sent in an upward direction through a flat drying zone section of the treatment belt and the air stream loosens and dries the fibers contained in the fiber mat;
- and
- capturing fly fibers moved by fly fiber movement in the air stream with a filter belt, which filter belt is arranged above the treatment belt and which filter belt is moved in the conveying direction;
- wherein a deposit of fibers formed on the filter belt is separated from the filter belt at an outlet of the fiber dryer, with the separated fibers being returned to the dried fibers on the treatment belt.
A fiber treatment plant for drying damp or wet textile fibers, the fiber treatment plant comprising a fiber dryer, which is essentially air-tight to an outside, the fiber dryer comprising:
- an air-permeable treatment belt, which can be moved in a conveying direction through the fiber dryer;
- a filter belt, which is arranged above the treatment belt and can be moved in the conveying direction;
- a middle chamber, which is formed between a drying zone section of the treatment belt and the filter belt, and
- an air circulating system, which is configured to form an air stream from a heated drying air, which flows in an upward direction through the middle chamber and a fiber mat, which can be laid on the treatment belt, so that the fibers in the fiber mat, are loosened and dried;
- wherein the fiber dryer has a return shaft, through which the fibers, which are separated from the filter belt, can be returned to the dried fiber mat.
