US 2019/0316839 A1 · TEXTILE FIBER DRYING

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).

Dependent claims

A drying process for drying damp or wet fibers, the drying process comprising the steps of:

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 the outside;
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.
