Definitions

  • the present invention relates to an improved method and apparatus for aftertreatment of a printed textile sheet by application of microwaves, and more particularly to improvements in continual aftertreatment of a printed textile sheet under emanation of microwaves for obtaining a uniform and ideal colour fixation and development.
  • Colour fixation and development on a textile sheet has since a long time been carried out by firstly passing the textile sheet through a dryer and, thereafter, subjecting it to steam heating.
  • microwaves refers to electro--magnetic waves having frequencies in a range from 300 to 30,000 MHz.
  • Microwaves have a wide variety of advantages in particular when used for treatment of a wet textile sheet. Firstly, they permeate into and heat the textile sheet very swiftly. Secondly, they can be selectively absorbed in an object with large dielectric loss, thereby heating only requisite sections of the object, since their heat generation is caused by dielectric loss. There is almost no heating of unnecessary sections of the object, thereby well avoiding waste of thermal energy generated by microwave emanation. Thirdly, when an object is exposed to microwaves, the object also generates heat by itself and such heat naturally raises the temperature of the ambient atmosphere. As a consequence, the amount of the thermal energy otherwise needed for heating the ambient atmosphere for the treatment can be greatly reduced.
  • microwaves usually cause almost sim- ultaneou-s temperature rise at different sections of an object exposed thereto.
  • regional variations in temperature within the object can be significantly minimized and this leads to ideal and uniform heating of the object.
  • heating conditions can easily and swiftly be controlled in accordance with demands in the actual treatment merely by adjusting the output voltage for microwave generation.
  • Exposing a textile sheet material to emanation of microwaves causes ionic conduction and dipole rotation of the fibrous materials composing the textile sheet, and of water and aqueous agents contained in the textile sheet. This is believed to result in swift and uniform heating of the textile sheet exposed to microwaves.
  • a printed textile sheet is transported through a confined chamber by a circulating and flexible carrier belt in order to be subjected to contact with steam and emanation of microwaves.
  • contact with steam proceeds concurrently with emanation of microwaves.
  • the textile sheet is exposed to microwaves after full contact with steam.
  • steam for contact with the textile sheet is generated by microwave generation.
  • FIG. 1 The first embodiment of the apparatus in accordance with the present invention is shown in FIG. 1, in which the apparatus includes a housing 1 defining a substantially confined chamber C for aftertreatment of a printed textile sheet F.
  • the apparatus is used in combination with a screen printer (not shown).
  • a screen printer for introduction of the textile sheet F into the confined chamber C, an inlet 3 is formed at one longitudinal end of the housing 1.
  • an outlet 5 is formed at the other longitudinal end of the housing 1 for delivery of the textile sheet F from the confined chamber C.
  • the walls of the housing 1 preferably have a hollow double construction at least in the sections surrounding the confined chamber C, and a number of heating tubes 7 preferably running through the inner spaces.
  • the heating tube 7 allows passage of any proper heating medium such as steam therethrough in order to keep up the temperature within the confined chamber C, and prevent dewing on the wall surfaces.
  • a horizontal bulkhead 9 is arranged at a proper level within the confined chamber C and divides the latter into upper and lower rooms.
  • This horizontal bulkhead 9 also preferably has a double construction made up of a lower rigid base 9a and an upper shelter plate 9b which blocks free passage of microwaves through the bulkhead 9.
  • the bulkhead 9 is preferably provided with vertically extending sections for controlled running of the later described carrier belt.
  • At least one emanator 11 of microwaves is secured to the housing 1 whilst opening in the upper room of the confined chamber C.
  • supply and exhaust conduits 13 and 15 are mounted to the housing 1 whilst opening in the confined chamber C.
  • the supply conduit 13 opens at a position on the side of the outlet 5 whereas the exhaust conduit 15 opens at a position on the side of the inlet 3 for the textile sheet F.
  • the supply,t-onduit 13 is coupled to a given n supply source 17 of saturated or overheated steam.
  • the opening of the supply conduit 13 is preferably encompassed by a perforated plate 19 which allows free passage of steam but not microwaves. Use of such a perforated plate 19 well prevents wasteful dissipation and dangerous leakage of microwaves via the steam system.
  • An endless carrier belt B is arranged within the confined chamber C for continual circulation partly in sliding contact with the top surface of the horizontal bulkhead 9.
  • This carrier belt B is made of a flexible material such as felt which is absorptive of water or other liquid substance.
  • this carrier belt B advances through a wet bath 21 and a heater 23 in order to always be kept at prescribed temperature and humidity.
  • the carrier belt B further engages a tension adjuster 25 in order to be properly tensed during its circulation.
  • Guide rollers 27 and 29 are arranged in order to keep the fixed circulation course of the carrier belt B. Either of the guide rollers 27 and 29 may be coupled to a given drive motor (not shown) so that the circulation speed of the carrier belt B can be positively controlled.
  • the carrier belt B is further brought into contact with a size applicator 31 after heating.
  • a carrier belt 33 from the preceding printing station terminates near the inlet 3 into the confined chamber C and a carrier belt 35 to the next operational station starts near the outlet 5 from the confined chamber C.
  • the textile sheet F brought from the preceding screen printing station by the carrier belt 33 is introduced into the confined chamber C via the inlet 3 and entrained on the carrier belt B on the top surface of the horizontal bulkhead 9 in order to travel towards the outlet 5 in contact with steam under emanation of microwaves.
  • the size applied to the surface of the carrier belt B by the size applicator 31 enables tensionless but snug surface contact of the textile sheet F with the carrier belt B.
  • the textile sheet F is kept at moderate temperature and humidity during its travel through the confined chamber C due to contact with the carrier belt B which is soaked and heated during its running through the lower room of the confined chamber C. Emanation of microwaves fills the confined chamber C with hot steam of 100 to 200°C temperature.
  • the textile sheet F with the carrier belt B advances in the upper room of the confined chamber from the inlet to outlet side whereas steam flows in the upper room from the outlet to inlet side.
  • This counter-march of the textile sheet F raises thermal efficiency of the steam greatly.
  • the flowing direction of the steam may be the same as the advancing direction of the textile sheet F in the upper room of the confined chamber C.
  • the printed textile sheet F shall be continually unwound from a roll of the printed cloth in the printing station and led to the inlet 3 of the housing 1 in any known manner.
  • the printed textile sheet is advanced through the confined chamber C substantially without any tension while being kept in a state moderately soaked and heated.
  • the emanated microwaves instantly permeate into the structure of the textile sheet in order to effectively generate heat due to their dielectric loss.
  • Selective absorption of the microwaves by the textile sheet ends in efficient utilization of heat for the aftertreatment of the printed textile sheet. This concurs to bring about improved fixation and development of colours printed on the textile sheet.
  • the process is greatly streamlined due to removal of the separate drying operation.
  • the textile sheet F was exposed to the microwaves concurrently with contact with the steam in the confined chamber C.
  • this concurrent system is liable to cause uneven colour fixation and development on the textile sheet obtained. This is in particular significant when the present invention is applied to aftertreatment of a textile sheet printed by screen printing.
  • a printed textile sheet just arriving from the preceding printing station includes size patterns of different moisture contents. Heating effect by microwave emanation varies greatly depending on the moisture content of the object exposed to the microwaves. Therefore, when a printed textile sheet is directly subjected to microwave emanation concurrently with contact with steam, heating effect by microwave emanation varies from pattern to pattern on the textile sheet. This naturally results in uneven colour fixation and development on the textile sheet. In order to obviate such unevenness, moisture content of the textile sheet should be adjusted so as to be uniform over the entire area before exposure to microwaves.
  • a vertical bulkhead 41 extends from the housing 1 towards the top surface of the horizontal bulkhead 9 whilst allowing free passage of the textile sheet F with the carrier belt B.
  • This vertical bulkhead 41 divides the upper room of the confined chamber C further into upstream and downstream rooms along the travelling path of the textile sheet F.
  • the upstream room forms a sort of moisture adjusting room.
  • the steam supply and exhaust conduits 13 and 15 in this embodiment both open in the upstream room whereas the emanator 11 opens in the downstream room.
  • a further supply conduit 43 preferably opens in the downstream room and is selectively coupled, via a shifter valve 49, to a supply source of steam 45 and a supply source of dry air 47.
  • a shifter valve 49 to a supply source of steam 45 and a supply source of dry air 47.
  • either steam or dry air is supplied to the downstream room via the supply conduit 43 by operating the shift valve 49.
  • the textile sheet F from the printing station is first brought into the upstream moisture adjusting room replete with steam supplied via the conduit 13 so that moisture contents of different patterns on the textile sheet F should be substantially equalized and the textile sheet F should be soaked sufficiently.
  • the textile sheet F is exposed to microwaves in the downstream room for heating. Heating by microwave emanation can be carried out quite uniformly over the entire area of the textile sheet due to the equalized moisture content, thereby assuring ideally uniform colour fixation and development.
  • the steam for contacting the textile sheet is supplied into the confined chamber C by means of the steam circulation system 13 and 15.
  • the third embodiment of the apparatus in accordance with the present invention shown in FIG. 3 employs a different system for generation of the steam. That is, generation of the steam is caused by emanation of the microwaves. This system greatly simplifies the construction of the apparatus by omitting the steam supply system used for the foregoing embodiments. In addition, dissipation of the steam generated is well prevented in order to assure most efficient utilization of thermal energy.
  • a roll 53 of a flexible sheet S is placed over the carrier belt 33 from the preceding printing station.
  • this flexible sheet S takes the form of an elongated polyethylene film or densely woven cloth which allows free passage of microwaves but not steam.
  • the woven cloth may contain glass or ceramic fibers.
  • the flexible sheet S is delivered from the roll 53, led into the confined chamber C via a guide roller 51 arranged near the inlet 3, and superimposed on the textile sheet F for concurrent running. Since the carrier belt B is soaked before contact with the textile sheet F, the flexible sheet S absorbes moisture from the carrier belt B through the textile sheet F as soon as the three layers come in contact on the horizontal bulkhead 9.
