Definitions

  • the present invention relates to a heterogeneous washing process in an aqueous medium of articles based on dyed cotton.
  • the stonewashing aspect is obtained by the action of stones in an aqueous medium, in the presence or not of bleaching chemicals depending on the degree of discoloration desired, at preferred temperatures of 20 to 70 ° C., while the stonewashing aspect snow is generally obtained by rubbing stones soaked in sodium hypochlorite or other powerful whitening agent, dry and at room temperature.
  • one of the conditions of the color enhancement is that no loss of dye accompanies the action of the cellulases during the washing, while a very significant release of the dye is an essential condition for the application of the cellulases in the present invention.
  • the aim sought by the addition of cellulases in detergents is to restore new appearance to aged clothing in use, while on the contrary that sought for cellulases in the present invention is to cause artificial aging of new articles. in cotton.
  • the object of the present invention is to provide a new method of washing articles made with fabrics made only of dyed cotton or based on dyed cotton associated with other textile fibers characterized in that said articles are brought into contact with '' an aqueous composition based on acid cellulases at a concentration of between 0.01 and 5 filter paper units per gram of dry tissue, at a pH below 6 and preferably between 4 and 5 and at a temperature ensuring heterogeneous washing rapid, whether or not pumice stones or amylases are present.
  • This method has several advantages, inter alia, of being compatible with the machines used for stonewashing, does not require a new reinvestment of the users in a new material, considerably increasing the longevity of these machines, to significantly simplify the tasks of the personnel assigned to these washing operations and finally to limit the problem of pollution of discharged water.
  • the cellulases enzymes of microbial origin
  • the washing water in which the articles based on dyed cotton are immersed and reacted with rotary stirring for a short time at their optimum temperature and pH condition, the latter being less than 6 and preferably between 4 and 5.
  • This is in fact the functional pH of most of the cellulases which can be used according to the invention.
  • Such a pH also makes it possible to avoid the resolubilization of certain dyes such as indigo.
  • a final acid wash can be carried out.
  • cellulases of fungal origin or of bacterial origin can be chosen in particular from those originating from the fungi Trichoderma reesei , Penicillium funiculosum , Humicola insolens and from various bacteria in particular, Cellulomonase firmi and Clostridium thermocellum .
  • the heterogeneous washing is obtained in industrial washing machines of different types in aqueous medium with cellulases in the absence of pumice stones.
  • cellulases can also be used as a stonewash activator according to at least two possible alternatives.
  • the cellulases are added to the aqueous media containing the articles to be washed and the usual amounts of stones, which results in a reduction of half or more of the time necessary to obtain the result of the process without the addition of enzymes.
  • the other possibility consists in adding the cellulases in an aqueous medium containing the articles to be washed out in the presence of stones but in greatly reduced quantities. In this case, the time of the washing operation is generally not reduced compared to the usual process with stones, the benefit being a lower consumption of the stones.
  • Trichoderma reesei cellulases must be used in the ratio of 0.5 to 4 filter paper units per gram of items to be washed by dry weight, depending on the texture of the fabric to obtain the best result and washing conditions (presence or absence of stones). A higher concentration is only justified when the reaction time must be reduced, a concentration below this range requires incubation times that are far too long for rational industrial exploitation. With regard to the other cellulases of bacterial and fungal origin, the most suitable concentrations of each of them are found in a significantly wider range of 0.01 to 5 units of filter paper per gram of dry article.
  • cellulases The action of cellulases is facilitated by a preliminary treatment of the raw articles with amylases to remove the starch finish and by the association with cationic, anionic or non-anionic detergents compatible with a given cellulase and with dispersing substances. and indigo antireposition in the case of very dark denim fabrics.
  • Another important aspect of the invention resides in the simultaneous use of amylases, enzymes for degrading starch and cellulases to carry out the deaerating and the washing in a single operation.
  • the simultaneous action of the two types of enzymes allows a simplification and a saving of time for the process implemented to obtain a faded article from the raw garment after making.
  • the optimal pH and temperature conditions used during the reaction of the cellulases with the articles to be bleached may depend on the enzyme used but are usually a pH between 4 and 5, preferably between 4.5 and 4.8 and a temperature of the order of 60 ° C.
  • the reaction time is approximately 1 hour.
  • the present invention generally relates to clothing or other manufactured articles made from dyed cotton fabrics which have been washed in a heterogeneous manner according to the invention.
  • Three denim fabric garments were purchased from a clothing store. The first was a denim canvas skirt, the second was a 501 blue jean by LEVI STRAUSS and the third was a blue jean in stretch fabric made of 98% cotton and 2% elastane Lycra. These three garments had been softened and shrunk by a simple wash. The same three types of stone washed clothing were also purchased to facilitate comparison with the first three items subject to the following processing:
  • the three items of clothing were placed in a household washing machine with front window (Miele Model W730). After putting in water and rotating the drum for 5 min. the machine is stopped, the pH of the water in the drum is brought to a value of 4.6-4.8 (measured with a pH indicator paper) with 10 ml of 100% acetic acid. Then 20 ml of a solution of CAYLASE 345 at 1.2 x 105 filter paper units per liter are added to the water (CAYLASE 345 is a cellulase from Trichoderma reesei sold by the company CAYLA). The enzyme concentration in this example is 2400 filter paper units for 1.7 kg of clothing.
  • the machine is restarted with a program of 60 minutes of alternating rotation of the drum with maintaining the water at 60 ° C followed by the emptying of the water which has turned dark blue and filling again.
  • the machine is stopped and the pH of the new water is brought to 11 with 10 ml of concentrated sodium hydroxide.
  • the machine is restarted with a program of 15 minutes of rotation at 60 ° C, emptying of the water again turned dark blue, rinsing, 2 washes, rinsing and spinning.
  • the three garments after drying in a rotary household tumble dryer (Philips, Model AMB508) are compared with the three equivalent garments washed in stones (stone-washed) purchased at the store.
  • the three garments have a characteristic aspect of stonewashing (more pronounced lightening at the level of belts, pockets and seams) with a brighter shine compared to the same stonewashed articles.
  • the two jackets have an aged appearance of the best effect, identical for the two garments and a perfect collar for the jacket whose collar was made with a fragile cotton fabric.
  • 60 raw canvas blue jeans are distributed in the two compartments of a used machine industrially for stonewashing (ATENOX, St Médars en Jalles, France) containing approximately 500 liters of water.
  • the temperature rose to 70 ° C by steam and the drum was rotated for 15 min.
  • the blue water is discharged and replaced by the same volume of water.
  • the pH is lowered to 4.5-4.8 with 500 ml of concentrated acetic acid and 1.5 l of Celluclast 1.5 L (9 x 104 units of filter paper / liter) (Novo) are distributed in the two compartments .
  • the concentration of enzymes in this example is 1.3 x 105 units of filter paper per 36 kg of pants.
  • the water temperature is brought to 60 ° C and the drum rotated for 45 min.
  • the appearance of the blue jeans was similar to that of pants of the same series washed in the same machine containing pumice stones, with however an improvement by an almost total absence of white mottling and a greater contrast of the white and blue colors.
  • 120 pants in raw denim fabric, thicker than in Example 2 are distributed in the two compartments of an industrial washing machine (MILNOR, New Jersey, United States).
  • the pH of the 500 liters of water is brought to 4.5-4.8 with 700 ml of acetic acid and after addition of 3 liters of CAYLASE P to 150 g / l of protein (1.35 x 105 units of filter paper per liter).
  • CAYLASE P is an enzyme preparation of Penicillium funiculosum containing cellulases and amylases, marketed by CAYLA), the temperature is brought to 60 ° C. After 10 minutes of rotation, 200 ml of acetic acid are added to bring the pH down to 4.5-4.8 and the washing is continued for 50 min.
  • the dark blue water is drained, and 500 ml of liquid detergent containing proteases (ARIEL) are added to the new water. After 15 minutes of rotation at 60 ° C. the rinsing operation is followed by two washes, a spin and drying.
  • ARIEL liquid detergent containing proteases
  • the quality of the washing of the clothes in this example was also higher than that of the pants of the same series washed by the stone method.
  • An ATENOX machine is loaded with 60 kg of raw jeans and 120 kg of pumice stone filled with approximately 500 liters of water heated to 60 ° C with steam.
  • the drum is rotated and 1 liter of CAYLASE 345 (2.4 x 104 filter paper units per liter) is added after the pH of the hot water has been adjusted to about 5 with 800 ml of acetic acid.
  • the machine is refilled with 500 liters of water and the drum is returned to spin for 30 min.
  • the water is drained and then washed with 2 kg of industrial detergent for 15 min. with cold water is followed by 2 rinses of 5 minutes.
  • the pants are removed from the machine, removed from the stones in the pockets, wrung out and dried.
  • the pants had a deep stone-washed appearance identical to those washed out by the same event sequences without the addition of enzyme.
  • the addition of the enzymes resulted in this example in time savings of 90 minutes out of a total of 3 hours for the proceeded only with stones.
  • a Milnor industrial washing machine is loaded with 60 casual jeans.
  • an industrial perborated detergent St Marc
  • the pants After drying, the pants presented a sought-after appearance characterized by a marked contrast between the white and blue parts.
