Why need the Fabric Drying Process?--ALIDO textile finishing machine
Fabric drying process is the frequency of textile finishing ,which requiring impregnation of the textile substrate (washing,impregnation in dyeing or finishing liquor, desizing and so on), consequently leads to the need of subsequent drying processes.With a high impact on processing costs, it depend on fabric properties of nature and structure,whether the textile fabrics absorb greater or lower quantities of water; the water absorbed by the textile material is partly retained between the fibres and in the pores of the fabric and partly more deeply in the fabric by the swollen fibres. The water between the fibres or on the fabric surface can be eliminated mechanically while the water in the swollen fibres can be eliminated with a drying processes.
Adjust the moisture content of fabric
The drying speed is determined by the difference between the tension of water steam on the textile surface and the tension of the water steam in the drying unit: it increases proportionally to the decrease of the moisture content in the air of the unit.In order to keep this content on low levels it is necessary to blow in the drying units huge quantities of heated air at the same temperature of the drying unit, which leads to huge energy consumption.When setting the desired moisture degree of the air in the drying unit, it is worth considering that the best degree results from a correct proportion between efficient output speed and cost-
effective energy consumption.
