Definitions

  • the present invention relates to a process for the continuous finishing, especially bleaching and/or desizing of knitted fabrics and hosiery goods, particularly cellulose fibers such as for example cotton, wherein the knitted fabrics and hosiery goods are impregnated in the treatment liquor, steamed, washed and/or rinsed and dried.
  • the knitted fabrics and hosiery goods of cotton have been subjected to wet-finishing processes, for example desizing, kier-boiling, boiling-off, bleaching and optical brightening as well as dyeing in rope form.
  • Treatment is effected discontinuously on a winch beck or in a treatment vat, whereby the material is exposed to the influence of the treatment medium for a sufficiently long time by letting it dwell in the respective treatment liquor.
  • continuuous processes and devices have already been suggested and used especially for dyeing and bleaching.
  • An object of the present invention is to avoid the prior art disadvantage in processes for the finishing of knitted fabrics and hosiery goods.
  • Another object of the present invention is to provide an improved process for finishing knitted fabrics and hosiery goods and to improve the quality of the product.
  • a further object of the present invention is to provide an improved process for finishing, especially bleaching, dyeing and/or desizing knitted fabrics and hosiery goods continuously in open width.
  • cotton materials which are to be desized and bleached continuously to a desizing process, for example with sodium bromite and to a bleaching process, for example with a peroxide, without drying the material between these two treatment steps.
  • a desizing process for example with sodium bromite and to a bleaching process, for example with a peroxide
  • the washing process for desizing and bleaching is omitted. This can be accomplished by impregnating and steaming the cotton material first with the desizing liquor, 'by dehydrating the material as much as possible by squeezing and/or vacuum extraction, by impregnating the material with the bleaching liquor, by steaming, washing and/or neutralizing said material and finally by rinsing and drying the material. If necessary, the material may be finished in the last bowl before drying.
  • the present process is rendered more economical by applying the desizing and bleaching liquor simultaneously or in two steps, by permitting the material to dwell in a steam atmosphere and by subsequently washing and/or neutralizing, rinsing and drying the material.
  • the material is dyed with suitable dyestuffs, for example with indanthrene dyes in one single process.
  • the treatment can be effected just like the combination desizing and bleaching process, that is either in one or in two bowls with a common steaming treatment or alternatively withone steaming treatment each for desizing and for dyeing.
  • At least one impregnating device preferably a suction drum bowl with a squeezer or a vacuum extractor connected therebehind,
  • a steamer preferably a conveyor belt steamer, that is one which is provided with a conveyor belt as the conveyor means, which can be provided with a folding device arranged in the steaming chamber.
  • the steamer can also be provided with sieve drums subjected to a suction draft as the conveying elements,
  • a sieve drum dryer preferably provided with a folding device at the discharge end of the apparatus,
  • a belt steamer it is advantageous if the folding device is arranged in the steaming chamber and if a blower is correlated to the steam-permeable conveyor belt which passes the steam through the folded material. As a result of the steam penetration the material is heated up shock-like and very uniformly so that the material turnout is uniform and the steaming time is reduced.
  • a J-box as a steamer in which the material is stacked in a well known way in the long leg of the I-box and drawn out of the short leg of said box. If only short steaming times are required it is advantageous to use a sieve drum steamer with sieve drums subjected to a suction draft in order to obtain a good material guidance.
  • FIG. 1 is a schematic design of a continuous treatment apparatus for kinitted fabrics and hosiery goods
  • FIG. 2 is a cross-sectional view of the steamer of the apparatus according to FIG. 1.
  • the apparatus of the present invention comprises a tube or length of knitted fabric or hosiery goods 1 drawn out of a container 2 where it is stacked and passed via a spreading device 3 to a suction drum bowl 4 where it is impregnated with the treatment liquor.
  • a squeezer 5 is correlated to suction drum bowl 4.
  • the material 1 is then fed via an inclined lattice belt 6 to a steamer 7.
  • the steamer is provided with an antechamber 8 subjected to a suction draft and with a water seal 14 by means of which a substantially air-free steam atmosphere is produced and maintained in the steamer.
  • a folding device 9 the material 1 is folded onto a steam-permeable conveyor belt 10.
  • a cross-current blower 11 is correlated with a heating device 12 for superheating the steam which is circulated by the cross-current blower 11.
  • the steam is passed through the material twice.
  • a heated sump 13 which is provided at the bottom of the steamer serves for the generation of saturated steam.
  • the steamer may also be heated by means of live steam.
  • a trough 15 is correlated to the discharge end of the steamer.
  • the material dropping into the trough is drawn off by means of a draw-off assembly 16 and passed on to suction drum bowls 17 for neutralizing and rinsing and possibly for the application of a finishing agent.
  • a squeezer 5 is correlated to each suction drum bowl.
  • a sieve drum dryer 18 with sieve drums 19 subjected to a suction draft is provided.
  • the dried material is packed into a container 21 by means of a folding device 20.
  • the steamer is used for dyestutf setting it is expedient not to fold the material but rather to handle it as a material length.
  • a sieve drum steamer can be used with advantage.
  • a spraying device can be employed instead of a suction drum bowl.
  • a continuous process for treating knitted fabrics and hosiery goods in open width which comprises spreading the material, impregnating the material with a treatment liquor, folding the material in a spread-out state in slight undulations, steaming the impregnated and folded material for a period of time, said material being treated with superheated steam during the initial portion of the steaming stage of the process, washing the steam-treated material and drying the washed material, said material being conveyed substantially without tension during the various stages of the treatment process.
  • washing stage also includes neutralizing and rinsing.
  • a continuous process of desizing and bleaching cellulose fibers in open width which comprises spreading the fibers, impregnating the fibers with a desizing liquor, folding the material in a spread-out state in slight undulations, steaming said impregnated and folded fibers for a period of time, said material being treated with a superheated steam during the initial portion of the steaming stage of the process, dehydrating said fibers, impregnating the fibers with a bleaching liquor, steaming said impregnated fibers again, washing the steam-treated fibers and drying the Washed fibers, said fibers being conveyed substantially without tension during the various stages of the treatment process.
