Definitions

  • This invention relates to the dyeing and finishing of lyocell and also polynosic fabrics.
  • Lyocell fibres are known. Lyocell is the generic name for shaped cellulosic articles made by dissolution of cellulose in a solvent without formation of a chemical derivative of cellulose, followed by extrusion of the resulting solution into a coagulating bath to form a shaped cellulosic article. Suitable known solvents include a variety of tertiary amine N-oxides, often in admixture with water. One such tertiary amine N-oxide is N-methylmorpholine N-oxide.
  • Polynosic fibres are also known. Polynosic is the generic name for regenerated cellulose fibres having a defined set of properties, made by the viscose process.
  • a lyocell yarn is a yarn which contains or consists of lyocell fibre
  • a lyocell fabric is a fabric which contains or consists of lyocell yarn.
  • Polynosic yarn and polynosic fabric are to be construed similarly.
  • lyocell fibre has a tendency to fibrillate.
  • Fibrillation is a phenomenon which may occur when lyocell fibre is subjected to mechanical stress in the wet state, notably during the fabric processing steps typically involved in dyeing and finishing operations.
  • the result of fibrillation is the partial detachment of fine fibrils from the body of the fibre, which can lead to a change in visual appearance and handle.
  • Considerable efforts have been made to reduce or control the fibrillation tendency of lyocell fibre, in particular by the use of suitably-chosen manufacturing conditions or by the application of cross-linking agents. Two types of fibrillation in lyocell fabric have been distinguished.
  • Primary fibrillation involves the formation of long fibrils, often 1 mm or longer and often unevenly distributed over the fabric. In severe cases, so-called white-line defects may be seen, where extensive fibrillation has occurred at creases in the fabric. Primary fibrillation confers an unsightly appearance on lyocell fabrics and is generally considered to be undesirable. Secondary fibrillation is the formation of short fibrils, a fraction of a millimetre in length, uniformly and densely distributed over the fabric. In contrast to primary fibrillation, secondary fibrillation can confer an attractive appearance and handle on a fabric, often aptly called a peach-touch finish.
  • a preferred route towards the attainment of a peach-touch finish involves: fibrillation (or prefibrillation) by subjecting wet fabric to mechanical stress, for example during processing in rope form, thereby inducing primary fibrillation; defibrillation, i.e. removal of primary fibrils, for example by treatment with an enzymatic preparation containing a cellulase,- and further fibrillation (or refibrillation) by subjecting the fabric to controlled mechanical stress in the wet state, thereby inducing secondary fibrillation and thus providing a peach-touch finish.
  • a conventional scheme for dyeing and finishing lyocell fabrics so as to provide a peach-touch finish involves the following steps in sequence. Scour the fabric, using an alkaline detergent solution, to remove sizes and other unwanted substances. Rinse with hot and cold water. Dye the fabric with a reactive dyestuff, if required in the presence of alkali (catalyst) . Rinse the fabric several times with hot - 3 - and cold water to remove unreacted dyestuff and to adjust fabric pH towards neutrality.
  • a typical rinsing sequence involves washing cold; washing at 70°C; washing at 40°C; boiling in detergent solution; washing at 70°C; washing at 40°C; and washing with cold water (seven steps).)
  • a method for dyeing and finishing a lyocell fabric or a polynosic fabric characterised in that it includes the steps of:
  • the fabric is often a woven fabric, although knitted fabrics may also be used.
  • the fabric may be prepared for dyeing in conventional manner. This typically involves scouring in open width with an alkaline detergent solution in order to remove sizes and suchlike materials from the fabric.
  • Equipment for the wet-processing of fabrics in rope form is known, for example jet-processing machines.
  • Suitable equipment for use in the method of the invention includes
  • the liquor used in dyeing step (1) may contain a salt such as sodium sulphate in known manner and as recommended by dyestuff manufacturers to assist the dyeing - 5 - process. If desired, the liquor used in dyeing step (1) may contain conventional fabric softening agents and/or lubricants .
  • the intermediate rinse which can precede step (2) is preferably omitted except in the case of deep and dark shades, obtainable by dyeing under alkaline conditions as more particularly described hereinafter.
  • the denaturing and refibrillation step (3) is conveniently performed by heating the liquor to a temperature in the range from 80 to 100°C and maintaining the liquor in contact with the fabric for sufficient time to achieve the specified effects.
  • the denaturing and refibrillation step (3) is succeeded by a rinsing step (3a) to remove salts, proteinaceous matter and fibrillar debris from the fabric.
  • the rinsing step (3a) may conveniently be performed using cold water.
  • a softening step in which a fabric softener is applied to the fabric is carried out immediately prior to the drying step (4) .
  • a conventional fabric softener is added to the bath containing the denatured cellulase at the end of the denaturing and refibrillation step (3) , and the fabric is subsequently dried without intermediate rinsing.
  • the softener is added to the rinsing water in the optional rinsing step (3a) .
  • the softener is padded onto the fabric after the optional rinsing step (3a) .
  • the drying step (4) may be performed in conventional manner. In suitable cases, it may conveniently be performed in the same equipment as used for the preceding wet-processing steps. In other cases, it may conveniently be performed on a tumbling machine. Continued tumbling of the fabric after - 6 - drying is complete serves to lift the pile of the fabric and to remove therefrom loose fibres remaining from the defibrillation step, and this is a preferred additional step in the method of the invention.
  • the pH of the dye liquor in step (i) may be controlled by addition of a pH buffer.
  • the amount of alkali added in step (iv) is preferably chosen in accordance with the recommendations of the dyestuff manufacturer .
  • the recommended dyeing temperature for many reactive dyestuffs is below 100 °C.
  • dyeing at a high temperature in the range from 100 to 150°C as in step (ii) has the advantages that primary fibrillation is more rapid and the handle of the fabric is softer.
  • Late addition of alkali in step (iv) to the cooled liquor has the advantage that alkaline hydrolysis of the dyestuff is minimised, thus increasing fixation efficiency.
  • step (1) when the exhausted liquor at the end of step (1) is alkaline, a preferred technique is to discard this liquor at the end of step (1) and to use in step (2) a solution of cellulase which contains a suitable pH buffering agent.
  • Reactive dyestuffs capable of reacting with cellulose in the absence of added alkali are also known.
  • dyestuffs include those made by reaction of a halotriazine with a tertiary amine to form a dyestuff containing a quaternary ammonium group.
  • An example of a suitable tertiary amine is nicotinic acid.
  • Dyestuffs of this kind are available commercially under the names Kayacelon React (Trade Mark of Nippon Kayaku Co. Ltd.) and Procion H-EG (Trade Mark of BASF AG) .
  • a method for dyeing and finishing a lyocell fabric or a polynosic fabric characterised in that it includes the steps of:
  • the dyeing step (A) is preferably performed at a temperature in the range from 100 to 150°C.
  • the pH of the dye liquor is typically slightly acid, for example in the range from 5 to 7, preferably 6 to 7, and accordingly contains no added alkali.
  • the pH of the dye liquor may be controlled by addition of a suitable pH buffer.
  • Dyeing at high temperature, for example at about 130 °C, has the advantages that the dyeing reaction is rapid, primary fibrillation is more rapid and the handle of the dyed fabric is softer.
  • Step (B) involves addition of a cellulase to the exhausted dyeing liquor from step (A) .
  • the cellulase is conveniently supplied and added in the form of a liquid cellulase preparation.
  • the liquor should if necessary be cooled to a sufficiently low temperature to avoid denaturing the enzyme upon addition to the liquor.
  • the pH of the liquor can be adjusted prior to addition of the cellulase.
  • a pH in the range from 4 to 6 and a temperature in the range from 20 to 70°C may often be found convenient, in accordance with the recommendations of the enzyme supplier.
  • the pH and temperature of the liquor during the defibrillation step (C) should be in accordance with the recommendations of the cellulase supplier. It was surprising to find that the defibrillation step (C) in the method of the invention proceeds normally, because it is often observed that the presence of extraneous substances can degrade enzyme activity.
  • the liquor may be made alkaline during step (D) in order to improve dye fixation.
  • a rinsing step and a softening step preferably follow the denaturing and refibrillation step (D) and precede the drying step (E) as described hereinabove.
  • the method of the invention occupies typically 8-9 hours and requires the use of two or three liquor baths. It thus offers considerable savings in both time and water usage compared with conventional techniques . - 10 -
  • the method of the invention may be used to dye blends of lyocell and polyester or of polynosic and polyester, in which case the dyebath will contain both reactive and disperse dyestuffs.
  • the method of the invention may also be used to dye blends of lyocell and polyamide or of polynosic and polyamide, in which case the dyebath will contain both reactive and acid dyestuffs; in the case of fixation under alkaline conditions, care should be taken to select acid dyestuffs with adequate fastness to alkali.
  • the method of the invention has the advantage that the number of cold-treatment steps is minimised. It has been found that rinsing or other treatment of lyocell fabrics with cold water during dyeing and finishing may lead to fabric damage
  • Fibrillation of lyocell fabrics may be measured by the following Test Method: -
  • Fibrillation Index (F.I.). Samples of fibre were arranged into a series showing increasing degrees of fibrillation. A - 11 - standard length of fibre from each sample was then measured and the number of fibrils (fine hairy spurs extending from the main body of the fibre) along the standard length was counted. The length of each fibril was measured, and an arbitrary number, being the number of fibrils multiplied by the average length of each fibril, was determined for each fibre. The fibre exhibiting the highest value of this product was identified as being the most fibrillated fibre and was assigned an arbitrary Fibrillation Index of 10. A wholly unfibrillated fibre was assigned a Fibrillation Index of zero, and the remaining fibres were evenly ranged from 0 to 10 based on the microscopically measured arbitrary numbers .
  • the measured fibres were then used to form a standard graded scale.
  • To determine the Fibrillation Index for any other sample of fibre five or ten fibres were visually compared under the microscope with the standard graded fibres . The visually determined numbers for each fibre were then averaged to give a Fibrillation Index for the sample under test. It will be appreciated that visual determination and averaging is many times quicker than measurement, and it has been found that skilled fibre technologists are consistent in their rating of fibres.
  • Fibrillation Index of fabrics can be assessed on fibres drawn from the surface of the fabric. Woven and knitted fabrics having F.I. of more than about 2.0 to 2.5 are normally found to exhibit an unsightly appearance.
