Problems solved by technology

In addition, the shrinkage process that occurs during drying is hindered in many cases, which leads to so-called loss of elongation during sizing, i.e. the elasticity of the warp yarn is greatly reduced

Embodiment Construction

[0023] Such as figure 1 As shown, the device for drying a yarn bundle 1 consists of a contact dryer 2 with a plurality of drying cylinders 10 and a convection dryer 3 . The warp beam frame 4 and the sizing device 6 for accommodating the warp beam 5 are placed in front of the contact dryer 2, the warp beam can unwind the yarn bundle 1, and the yarn bundle 1 is transported into the sizing device. Arranged downstream of the convection dryer 3 is a twisting device 7 and a warping machine 8 , where the yarn bundle 1 can be wound onto a warp beam 9 .

[0024] according to figure 2 , The contact dryer 2 is composed of five heatable drying cylinders 10, which are rotatably supported on the machine base. In this example the drying cylinders 10 are arranged on two levels such that they have a common horizontal tangent. The horizontal distance between two drying cylinders 10 is roughly equal to their radius. At the inlet of the contact dryer 2 a deflection guide roller 11 is arrange...

Abstract

The invention relates to a method for drying a bundle of yarns composed of fluffed yarns, comprising a pre-drying and a final drying, wherein the pre-drying is contact drying and the final drying is convection drying, in this method Produces smooth yarn with minimum fuzz and achieves optimal yarn shrinkage. The invention also relates to a device for carrying out this method, which device consists of a contact dryer and a convective dryer, the contact dryer and then the convective dryer as seen in the direction of movement of the yarn bundle, wherein The contact dryer consists of a plurality of heating cylinders to which a heat medium can be applied. The heating cylinders are respectively wound as far as possible by separate or integrally undivided continuous yarn bundles. The convection dryer is a cross-flow dryer.

Description

technical field [0001] The invention relates to a method for drying yarn bundles, in particular yarn bundles consisting of fluffed yarns, and to a device for implementing the method. [0002] Such devices are used, for example, in textile pretreatment after sizing of warp yarns, in order to evaporate the moisture applied by the sizing agent. Background technique [0003] DE-OS 1 914 231 describes a drum dryer for continuous warp threads, in front of which a pre-drying device is arranged. This device is made up of a discharge opening according to the overall width of the warp yarn and a feed opening arranged on the opposite side. The warp yarns move between two spouts. The hot gas flow leaving the discharge opening substantially perpendicular to the warp yarns is discharged from the feed opening after flowing through the warp yarns. The pre-drying device is supposed to prevent the warp threads from sticking to each other on the drums of the downstream drum dryer. A disadv...
