Definitions

  • the present invention relates to a process for desizing and bleaching in a single operation of fabrics or similar compositions based on textile fibers.
  • the purpose of desizing is to eliminate the sizing products applied beforehand to the warp threads to promote their behavior on the loom, as well as the products possibly applied to the weft threads.
  • the sizing products of the threads before weaving can be based either on starch dispersions alone or in admixture with starches more or less chemically transformed, or polyvinyl alcohol derivatives, or polyacrylate derivatives, or etherified cellulose. .
  • the sizing products can be more or less retained in the fabric depending on the drying temperature, the twist of the thread and the texture of the fabric.
  • Desizing is generally carried out by impregnation in an enzyme and surfactant bath heated to a temperature between 60 ° C and 75 ° C.
  • the impregnated fabric can be either left in deposit or vaporized at a temperature of 100 ° C. It is then washed at 95 ° C then at 60 ° C and, possibly with running water.
  • the scouring which aims to saponify the cotton fats and to solubilize the woody residues, is carried out in caustic soda medium and at a temperature between 100 ° C and 140 ° C.
  • bleaching is to oxidize the impurities which are part of the unbleached or already boiled fiber of cotton, linen or any other cellulosic fibers. It is carried out in practically all cases with oxidants such as hydrogen peroxide, peroxides and alkaline persalts, peracetic acid, sodium hypochlorite, sodium chlorite, etc.
  • Desizing, scouring, bleaching operations are generally carried out in an aqueous medium and under hot conditions. Each of them is followed by hot and cold washes resulting in significant consumption of water and energy.
  • the object of the present invention is to reduce the number of operations for preparing tissue based on cellulosic fibers, alone or in admixture with one another or with other regenerated or chemical fibers, such as viscoses, polyamides and polyesters and provides a new process in which desizing and bleaching are combined in a single operation.
  • the single operation desizing-bleaching process of the present invention is carried out in a bath comprising hydrogen peroxide, a base such as sodium hydroxide, optionally a stabilizing agent such as sodium silicate, a sequestering agent such as sodium salt of diethylenetriamine pentacetic acid (DTPA), an enzyme preparation based on a starch degrading enzyme and a surfactant.
  • a base such as sodium hydroxide
  • a stabilizing agent such as sodium silicate
  • a sequestering agent such as sodium salt of diethylenetriamine pentacetic acid (DTPA)
  • DTPA diethylenetriamine pentacetic acid
  • the present invention relates to a process for desizing and simultaneous bleaching of fabrics, characterized in that the single operation of desizing and bleaching is carried out in a bath whose pH is between 10 and 10.5 and which comprises peroxide hydrogen, sodium hydroxide, a sequestering agent, an enzyme preparation based on a starch degrading enzyme and a surfactant.
  • An enzymatic preparation which can be used according to the invention is for example that which is the subject of German patent application DE-A-2909396.7, consisting of an intimate mixture of a starch degrading enzyme, such as an amylase. , and a nonionic surfactant belonging to the group of alkyl and alkyl oxalkylates in water.
  • a suitable enzyme preparation will, for example, consist of 10 to 40 parts by weight of an aqueous enzyme preparation and 10 to 60 parts by weight of a nonionic surfactant. Particularly satisfactory results are obtained using one of these enzymatic preparations marketed by the brand ENZYLASE C, by the company DIA-MALT.
  • a desizing-bleaching bath usable according to the invention can for example comprise:
  • the treatment is followed by washing at 90 ° C - 95 ° C, 60 ° C and cold.
  • the washing bath at 90 ° C - 95 ° C can advantageously include an addi tion of alkaline elements, caustic soda, sodium carbonate, trisodium phosphate as well as surfactant detergents.
  • One of the advantages of the process according to the invention is that it eliminates a wet desizing operation carried out at a minimum temperature of 60 ° C - 65 ° C, as well as several washing baths at temperatures of 90 ° C - 95 ° C.
  • the application of the method also removes a “wet on wet” impregnation, that is to say wet tissue entering a bath containing the bleaching products. It is known that this treatment causes a number of constraints: preparation of a more concentrated bath, maintenance of the impregnation bath at level and at constant concentrations, which involves either manual control or automatic regulation.
  • the characteristics of the fabric thus treated are excellent: high degree of whiteness, elimination of almost total sizing, instant hydrophilicity, degree of well-managed polymerization.
  • a 195 g / m 2 flea cotton fabric, 182 cm wide, 55.3% reflectance measured with an ELREPHO ZEISS filter n ° 8 filter, wavelength 457 nanometers, starch content 5.05% intended for the printing in reactive dyes was directly impregnated in ecru in a bath containing: The pH is between 10 and 10.5.
  • the impregnated fabric After spraying at 95 ° C, the impregnated fabric is rolled up in a heat-insulated chamber where it remains in reaction for 1 to 2 hours.
