Definitions

  • the invention relates to a "stenter machine”.
  • the stenter machine as described herein includes any textile machine such as tenter, dryer and the like machine in which a fabric in stretched and/or unstretched condition is dried and/or stabilized by heating. More particularly this invention relates to a stenter machine in which fabric is heated in the heating zone of the machine, by radiation, through hot plate(s) provided either below and/or above and below the fabric and heated by gas burner(s), without using any blowers, and heat of the exhaust gases is also utilized for direct heating of the fabric thereby reducing the length of the heating zone and drastically reducing the fuel cost and/or pollution, and high quality of stabilization of a fabric is achieved by providing fabric temperature sensor, measuring desired temperature of fabric at the exit end of the heating zone and signals of the said temperature sensor being utilized for controlling the fabric speed.
  • BACKGROUNDART Polymer like the polyester are thermoplastic, they soften when heated and harden when cooled.
  • synthetic or blended fabric is subjected to various strains which cause shrinkage during wet processing or washing and this shrinkage is called relaxation shrinkage.
  • the strains can be nullified by heat setting, i.e. by heating the fabric, while keeping it under dimensional control, to a temperature of about 30°C higher than the temperature used in wet processing or was ng.
  • heat setting of the fabric it is heated to the required temperature of about 180°C to 210°C through out its cross-section.
  • Such heat-setted fabric becomes dimensionally stable.
  • stenter has been developed, in which jets or streams of hot air come into contact with the fabric.
  • Stenter has two main features, a high intensity convection heating system and provision for fabric width control.
  • the latter is necessary because practically in all processing stages the fabric is subjected to longitudinal or warps wise tension to varying degrees and hence it shrinks widthwise to varying extent at different sections along its length.
  • Width control is effected in stenter with the help of a series of clips or pins mounted on a pair of endless chains. The clips or pins grip the selvedges of the wet fabric and adjust the fabric to the required width as it is dried in the stenter.
  • the heating section consists of a series of high velocity air jets. The air used is heated to temperature levels of the order of 180 ° C to 210° C, usually in heaters/radiators.
  • the stenter which is presently in use in the textile industries mainly comprises a fabric feeding system, a heat-setting system and a fabric receiving system.
  • the fabric feeding system consists of a set of rollers, which stretches the fabric widthwise and feeds it in to the heat setting system.
  • the heat-setting system consists of a plurality of heathig chambers and cooling chambers through which fabric passes in fully widthwise stretched condition with the help of a series of pins/clips mounted on a pair of endless chains which are moving in heat-setting system.
  • Each of heating chamber is provided with a pair of air blowers attached to a pair of air ducts having perforations for producing air jets, a pair of heaters/radiators/gas burners for heating the air, a pair of air filters for removing fumes and loose fibers, to prevent them from entering the heaters/radiators/gas burners and blowers.
  • An exhaust fan and a damper is also provided in an exhaust/out-let of the heating chamber for occasionally discharging the air in to the atmosphere in order to control the humidity and air volume and pressure inside the heating chamber. Air heated by the heaters/radiators/gas burners is blown by the blowers in to the perforated ducts and the hot air jets/streams strike the moving fabric from its top and bottom sides.
  • the hot air is recirculated in heating chamber continuously. After heating the fabric upto a required temperature of about 180° C to 210° C, in a number of heating chambers, the fabric passes in to the cooling chambers, where the cool air in the form of air jets/streams passes over the moving fabric from its top and bottom sides, there after the fabric is rolled or pleated in the fabric receiving system.
  • the main draw back of the existing stenter is that it is not thermal efficient and thereby is not economic. There is huge wastage of thermal/heat energy.
  • the heat is wasted in initial heating of the air, inside the heating chamber
  • the air as well as the fabric are heated by convection i.e., heaters/radiators which are generally thermic oil heaters or steam heaters are having heating media inside the tubes and air passes over the tubes, hence the heat transfer efficiency is very low.
  • a lot of heat is wasted when the hot air is exhausted out of the heating chamber. Due to a large volume of hot air being circulated continuously in heating chamber, there is a heat loss through the chamber walls. Outside air enters the heating chamber through the fabric inlet/entry and similarly hot air leaks out of the heating chamber through the fabric exit, which also adversely affects the thermal efficiency of the stenter. Due to low thermal efficiency a large number of heating chambers are required which increase the size of the stenter and thereby wastage of materials, and electric power used for operating blowers and larger endless chains.
  • This infrared electric heating stenter could not be commercially used, as it is very costly and expensive in terms of operational cost, electricity is also not readily available in many places or there is a heavy electric power cut or breakdown. Further drawback of this stenter is that, in this stenter speed of the fabric is kept constant and temperature is controlled by controlling the various heating panels, hence the productivity remains low.
  • the main object of this invention is to over come the above described draw backs of the existing stenters and to provide a gas heated stenter which is very economic, pollution free and in which there is no need of air circulation and in which heating of fabric takes place by radiation, through gas heating, there by completely eliminating the use of pollution generating fuel and at the same time dispensing with the filters, hot air blowers, perforated air ducts, exhaust fan and damper along with the typical heating chambers which are essentially used in the existing stenters.
  • a further objects of the present invention is to provide a gas heated stenter in which the fabric is heated to the desired temperature, uniformly through out its width/cross section, thereby resulting into better heat seating or better f shing of the fabric.
  • a further object of the present invention is to provide a gas heated stenter, which requires very less maintenance, as there is no hot air blower, air duct, air filter damper and exhaust fan and thus reducing break down time resulting into higher productivity.
  • a further object of this invention is to provide a gas heated stenter which is very easy to transport, easy to assemble and install, as there are comparatively less number of parts, and which requires simpler and cheaper frame work and foundation.
  • a further object of this invention is to provide a gas heated stenter hi which temperature is kept constant as desired for heat setting of a fabric and speed is controlled by using a sensor at the exit end of the fabric resulting into higher productivity for the same length and energy consumption of the stenter.
