Definitions

  • ABSTRACT OF THE DISCLOSURE A process for desizing, scouring and bleaching cotton and polyester fabrics in a continuous operation comprised of the steps of impregnating the fabric with a cold aqueous solution of hydrogen peroxide at a concentration of between 30 to 80 grams per liter, passing the fabric through a chamber filled with saturated steam at atmospheric pressure and at a temperature between 90 and 100 C. for a period of time not exceeding 20 minutes, immersing the fabric in water at about 90 C., steaming the fabric for about 2 to 3 minutes, washing the fabric in water at least 3 separate times each time for a very brief period and at a progressively lower temperature and squeezing the fabric to remove a high percentage of the moisture.
  • This invention relates to a bleaching process which. is particularly suitable for pure cotton fabrics or fabrics in which cotton is admixed with other natural, artificial or synthetic fibers.
  • the process according to the invention is, broadly speaking, characterized in that the operations of the desizing, scouring and bleaching are effected in a continuous manner on the full width of the piece of fabric, without any intermediate stops and in an ambient at atmospheric pressure, with only the help of non-acidic aqueous solutions, heat, hot water and steam.
  • Sodium hypochlorite process (NaClO), comprising the steps in a distinct operation sequence of: desizing, scouring in full-width piece, a treatment in an autoclave under superheated steam pressure-bleaching with sodium all 3,377,131 Patented Apr. 9, 1968 hypochlorite, acid antichlor treatment, neutralization of the acid e.g. with alkalies (Na CO)
  • NaClO Sodium hypochlorite process
  • steps desizing, scouring and impregnation with a chlorite solution, rolling up on rotatable drums and evolution of chlorine dioxide in a closed zone which is absolutely gastight, for a prolonged time period and at high temperatures, followed by repeated washings.
  • the impregnation of the fabric, in full width (the fabric could be dry or wet), in the cold, is made with an aqueous solution containing hydrogen peroxide at a concentration of from 30 to gms. per liter, e.g. 40 gms. per liter.
  • an aqueous solution containing hydrogen peroxide at a concentration of from 30 to gms. per liter, e.g. 40 gms. per liter.
  • ROCESA a solution available in the market under the registered trade mark ROCESA can be used.
  • the article is a Madapolam fabric, 70 pieces of 8,400 meters total length, width 90 cms., grams per square meter 130 approx, 100% cotton.
  • a process for desizing, scouring and bleaching cotton and polyester fabrics in a single continuous operation comprising impregnating the fabric with a cold aqueous solution of hydrogen peroxide at a concentration of 30 to 80 grams per liter, passing the fabric through a chamber filled with saturated steam at atmospheric pressure and at a temperature between 90 and 100 C. for a period of time not exceeding 20 minutes, immersing the fabric in water at about 90 C., steaming the fabric for about 2 to 3 minutes, washing the fabric in water at least three times at a lower temperature eachtime, and squeezing the fabric whereby all of the foregoing steps are carried out with the fabric at full width.
  • a process as set forth in claim 1, characterized in that the step of washing the fabric at least three times the first washing takes place with the water at 80 C, for a period of time of about two to three seconds, the second washing takes place with the water at a temperature of about 70 C. for a period of time of about two to three seconds and the third washing takes place in water
