VERTICAL YARN DYEING MACHINES MOD. GS

These vertical dyeing machines are the result of a continuos improvment working in straight contact with big dye-houses and big groups both in Italy and worldwide In these machines, working with air pad system, bobbins are charged completely submerged into water and air is never in contact with material, while air pad pressure is maintained perfectly constant and regulated by controller. Air pad is free volume to expand bath with temperature increasing, without using external expansion tank There are many advantages using air pad system. Bath is never in contact with external air and so is not...

Pump is designed to work with low flow and big prevalence to dye materials like rayon, cotton, linum and can work also with big flow and low prevalence to dye materials like wool, acrylic, polyester. This is obtained only changing inverter speed Pump is completely in stainless steel with carbon vidia seal and viton orings Pump volume and inversion device volume are keeped low allowing small liquor ratio also at minimum loads

Magnetic flow meter (see figure), allows to regulate pump speed keeping constant flow trough material; it can be setted in liters/min or liters /min*kg. This instrument is connected as input to controller Differential pressure electronic transmitter, DP, connected to controller, allows dyeing while keeping constant value of differential pressure In to OUT and OUT to In separately. It permits dyeing with constant flow , also when changing machine load from minimum to maximum or changing material density. Inverter speed is automatically varied to obtain constant differential pressure

Setting a value of differential pressure in controller, when bobbins density changes with temperature flow will increase causing mechanical deformation of winded material and dye centres mechanical deformations. To avoid this is necessary to limit flow with flow meter. So using together flow meter and differential pressure measurement machine can dye every kind of material in all load conditions. Also dyeing is done under optimal conditions to save electrical power because inverter power is always controlled to achieve desired flow values. Machines can be fitted also with air squeeze function...

Kind of carriers: CARRIES. 1 - for bicMik-a] bolibins 2 - for cylintiricaS bobbins 3 - for cheeses 4 - for fops 5 - for bum|is (5 - for looses fibres in overla|jpina modular basket

Machines can dye all kinds of materials, bobbins, hanks ,tow, top in bumps, zippers, ribbons, fabric, hairs changing kind of carriers. In all machines is present overflow rinsing function using a valve placed in top of the lid, water input in kier is opened from bottom and pump circulating from inside to outside. On this way perfect cleaning of machine is guaranteed and also complete washing of material after dyeing Automatic closing and open lid under 3 safety conditions (pressure, temperature and volume), so cycle is completely automatic from loading to unloading. Lid has interlock device which...

All tanks have analog level control so all products injected in machines are controlled in quantity and all dosing curves are present (linear progressive regressive). Each tank is equipped with water valve for rinsing, drain valve, transfer valve. All machines can be coupled, doubling loading capacity All kind of dyeing controllers or industrial PC can be fitted in electrical panel. Technical data Maximum temperature: 140 °C Maximum pressure: 5 bars Machine completely in stain steel AISI 316 L Max working pressure heat exchanger: 15 bars Motors: IP 55 insulating class H (210 °C) Heating gradient...
