Technical field
The utility model relates to a kind of flat wash trough without additional tension, belongs to textile dyeing and finishing equipment technology.
Background technology
Flat wash trough involved by the utility model is in textile dyeing and finishing technical process, be used for open width washing fabric a kind of plant equipment.
Fabric, in dyeing and finishing procedures, when being run by roller drawing Yi feeding, generally will form two kinds of tension force: one is initial tension, so-called initial tension, is the equilibrant force applied by straight displacement elastic devices (3 roller).Described initial tension, under the prerequisite meeting fabric corrugationless, steadily feeding, should be better less.Another kind is additional tension, on fabric feeding working line, generally all can arrange a lot of passive fabric guide roll (unpowered driving), is used for supports fabrics and guiding fabric feeding.And fabric feeding runs and will lead the passive fabric guide roll of Yi, this just must overcome frictional resistance moment and the additional tension that produces of gravity inertial moment of the rotation of passive fabric guide roll.This additional tension, the tension increment produced by the multiple upper and lower fabric guide roll of fabric flat wash trough is appreciable.
And in fabric open width dyeing and finishing Continuous maching, what fabric radial direction was born is the summation of initial tension and additional tension.When described tension force is large, the quality problems such as fabric pincher, looped weft and washing shrinkage be not up to standard can be formed, and directly affect the storage rate of finished textile product.
