Definitions

  • This invention relates to methods for treating textiles, and, more particularly to treating textiles with enzymes.
  • Enzymes are widely used in textile treatments, for example in industrial processing such as desizing of cloth and stonewashing of denim, or to impart enhanced fabric properties such as pilling properties and hand. Enzymes are also used in domestic laundry products to assist in cleaning soiled and stained fabrics and to counter the appearance of surface fibre.
  • cellulases have been used to treat cellulosic, particularly cotton goods and specific enzyme activities can be tailored for producing specific effects, whilst reducing or avoiding deleterious effects.
  • Enzyme treatment is carried out on textiles using a variety of methods and machinery.
  • Rotary dyeing machines, winches, jet dyeing machines and drum washers are all in widespread use and have the common feature that the textile is subjected to a high degree of agitation over a prolonged period of time.
  • Many of the more desirable effects, such as defibrillation are only fully achievable when the textile is subject to significant mechanical action and even abrasion during processing.
  • Treatment conditions during enzyme treatment are carefully controlled, both as to pH and temperature. Generally, treatment is carried out at somewhat elevated temperature, around 45-55° C., in a solution of which the pH is in the range 4.8-5.5 for acid cellulase systems, or 4.8-8 for neutral enzymes.
  • Enzyme treatment of cellulosic goods invariably leads to a reduction, even if only a slight reduction, in fabric properties such as tensile or tear strength, and there is also a measurable weight loss involved, which is partly due to the mechanical agitation involved in the processing.
  • the present invention provides new processes for textiles, notably cellulosic textiles such as cotton and flax, which enhance their properties in ways not previously contemplated in the context of enzyme treatment, and which do not adversely affect textile properties to the same extent as conventional enzyme treatment.
  • the invention comprises, in one aspect, a method for treating textiles comprising applying to the textile an enzyme having a specific activity towards the textile under conditions such that there is substantially no mechanical agitation.
  • An enzyme-containing composition may be applied to the textile by soaking or by padding, for example.
  • the enzyme composition may be left in contact with the textile for an extended period of time under ambient conditions, for example, for five hours or more, even up to ten or twenty hours.
  • the textile may subsequently be washed to remove unreacted enzyme.
  • An important effect of this treatment is to improve the dimensional stability particularly of cotton and other cellulosic fabrics, such as flax, and viscose rayon.
  • Enzymes found to be particularly useful in this regard are cellulases such as Biotouch L, cellulase F or cellulase H, all commercially available from Rohm Enzyme Finland OY, or mixtures or any two or all three thereof.
  • Other enzymes, some yet to be developed, will be found useful, these, however, being the most advantageous investigated to date.
  • the enzyme may be applied at an add-on of 0.1 to 10 mg total protein per gram of textile.
  • the textile may comprise more than one fibre type, and may indeed comprise blends of cellulosic and non-cellulosic fibres, for example cotton-polyester blends.
  • the enzyme system may comprise more than one enzyme so as to have specific activities specific activity towards different fibres types.
  • Textiles which can be treated include woven and knitted fabrics as well as non-wovens and even yarns. Fabrics may be treated by cold batch padding, the treatment being carried out over prolonged periods, or simply by soaking. Yarns may be treated on hank or shein or even on the package, just being left to soak at room temperature for up to twenty hours or longer.
  • the cellulolytic reaction may be stopped by immersing the textile in a 5% solution of sodium carbonate, and the textile may then be rinsed, for example, three times, with agitation, then dried in whatever manner is appropriate.
  • the cellulases Biotouch L (a Trichderma reesei secreted cellulase, commercially available from Rohm Enzyme Finland OY), cellulase F and cellulase H (from the same supplier) were applied to a 100% cotton fabric woven from ring spun yarns (205 g/m) with a heavy-duty padder.
  • Each enzyme was applied in solution at three different add-ons, namely 0.2, 1.0 and 5.0 mg of total protein per g of fabric, and was buffered with 0.1M acetate buffer, pH adjusted to 5.0 with sodium hydroxide.
  • the pick-up rate was (65 ⁇ 5)% (percentage weight of enzyme liquor per weight of fabric).
  • the fabrics were then rolled up and kept rotating for 17 hours at ambient temperature (approx. 20° C.).
  • the cellulolytic reaction was then stopped by immersion in a 5% solution of sodium carbonate and the fabric rinsed in three consecutive cycles, without detergent, the first rinse in water at approximately 60° C., agitated for 10 minutes, the second in warm water (40° C.) agitated for five minutes, the third in cold water, agitated for five minutes, after which the fabrics were dried.
  • Example 1 On denim fabrics, the treatments according to Example 1 showed cellulase F, again, to give best results, a lighter denim fabric having an improvement in shrinkage of about 25% with a strength loss of only 4.5%, a heavier fabric registering an improvement in shrinkage of about 35% with a loss of strength of only 3.3%.
  • a 50% /50% cotton/polyester bed linen fabric treated as in Example 1 at 70% pick-up showed a 53% improvement in shrinkage on treatment with cellulase F (5.0 mg/g) with a loss of strength of 5%.
  • a 100% viscose fabric treated as in Example 1 showed a 30% improvement in shhrinkage with a strength loss of about 6.3% when treated with cellulase F at 50 mg/g.
  • cellulase F outperformed cellulases Biotouch L and H, though they too showed useful improvements in shrinkage with somewhat greater loss of strength.
  • cellulase F outperformed cellulases Biotouch L and H, though they too showed useful improvements in shrinkage with somewhat greater loss of strength.
  • different enzymes will have different effects on different fibres, and other enzymes may yet be discovered to outperform cellulase F.
  • Treatment with enzymes without agitation for the purpose of improving dimensional stability may be carried out as a pre- or post-treatment to treatment with other enzymes for improving other properties under the usual elevated temperature and agitation conditions.
  • the method may not be limited to cellulosic fibres. Enzymes exist that have effect on other matural fibres, such as wool, and enzymes may be found to have similar effects on synthetic fibres.
  • Bleached ecru cotton yarn ( ⁇ fraction (1/20) ⁇ Nm count) was wound onto a dye spindle for a Pegg yarn package sample dyeing machine.
  • Four spindles were prepared, three for treatment with enzyme, the other as a control.
  • the prepared control yarn package was loaded in the sample dyeing machine. Water containing sodium acetate buffer to give a pH value of 5.0-5.5 (prepared from acetic acid and sodium hydroxide) was circulated at 40° C. The machine was set to automatically reverse the flow through the package every five minutes, and the treatment was continued for eight hours. At the end of the treatment process, the yarn package was rinsed in a solution of sodium carbonate (at a concentration of 1 g/l) at 80° C. for ten minutes, then rinsed twice with warm (50° C.) water and cold water. The yarn package was removed and dried in a radio-frequency dryer.
  • Water containing sodium acetate buffer to give a pH value of 5.0-5.5 prepared from acetic acid and sodium hydroxide
  • the dried yarns were knitted on a hand-knitting machine to give suitable fabrics.
  • the dimensions of each fabric square were measured before and after washing and tumble drying in a domestic washing machine.
  • the treated fabrics showed a significant reduction in dimensional change (shrinkage) amounting to 10%, 15% and 32% respectively for the treatment levels 0.2, 1.0, 5.0 mg protein /g yarn.
