Abstract:
Device for the wet treatment of packed and similar textile materials, comprising a hermetically locked enclosure, containing the treatment bath for the material, and the interior of which is divided into two chambers. One of these chambers communicates with the interior of the perforated cores which carry the packed material to be treated and their perforated tubular supports and the other chamber communicates with the outside of these cores. Both these chambers are separated by a volumetric alternating treatment bath impelling mechanism, this mechanism is of a type made up of a piston, a membrane pump or rotating pump. Said alternating treatment bath impelling mechanism impels, during every one of its to and fro strokes a part of the treatment bath and compels it to pass through the textile material or, respectively, from the inside of same towards the outside and from the outside towards the inside. The treatment bath volume which each time flows through the textile matter from the outside towards the inside of same is being kept enclosed in said chamber which communicates with the inside of the perforated tubular supports which support the textile material, and is at same time kept separated from the remainder of the total treatment bath volume which has not passed through the textile matter.
Abstract:
DEVICE FOR THE WET TREATMENT OF TEXTILE MATERIALS, SUCH AS FABRICS IN ROPE FORM, COMPRISING TWO VENTURI INJECTORS OF THE CENTRAL SUCTION TYPE, THEIR RELATIVE POSITION BEING SO THAT THEIR OUTLETS ARE POSITIONED OPPOSED TO EACH OTHER. THE TEXTILE MATERIAL TRAVELS IN A CONTINUOUS FROM THROUGH THE CENTRAL SUCTION CONDUITS OF THE TWO INJECTORS INTO THE OUTER CONDUITS OF THE SAME WHERE THE TREATMENT FLUID IS INJECTED THROUGH REGULATING DEVICES WHICH PERMIT VARIATION OF THE FLUID FLOW QUANTITY SUPPLIED TO EACH INJECTOR BETWEEN 0% AND 100% OF THE TOTAL FLUID FLOW, AND, IN THAT WAY, THE SUCTIONAL POWER OF EACH INJECTOR. THIS DETERMINES THE FORWARD FEEDING OF THE FABRIC IN THE DIRECTION WHICH CORRESPONDS TO THE INJECTOR WITH THE GREATER SUCTIONAL POWER, AND THE OPPOSITE INJECTOR WITH THE SMALLER DRAWING POWER PRODUCES A SLOWING DOWN AND COMPACTATION EFFECT ON THE FABRIC.
