Definitions

  • the present invention relates to a method for the continuous treatment of a web of wool slivers to impart shrink-resistance.
  • the present invention relates to a shrink resist treatment of wool sliver which avoids chlorination and makes it possible to treat wool webs of wool sliver at high speeds and also to treat wool webs with slivers of weights of 20 ktex or above.
  • shrink-resist wool An increasing amount of wool is subject to shrink-resist treatments in order to impart machine washability or easy care properties and many such methods have been described.
  • the most common approach to shrink-resist wool involves first subjecting the wool to an oxidative treatment and then to a polymer treatment. This is discussed in detail by K.R. Makinson in "Shrinkproofing of Wool", Marcel Dekker Inc. New York 1979.
  • the most common type of oxidative treatment used to shrink resist wool involves chlorination, either with elemental chlorine as a gas or in aqueous solution, solutions of hypochlorous acid or its salts, or with organic chlorinating agents such as N, N'-dichloroisocyanuric acid or its salts. Bryne et al, Proc. 9 th Intern.
  • Shrink-resistance is not an absolute property.
  • the level of shrink-resistance (usually quantified by determining the amount of change in area or length of a piece of fabric after a defined wash test) will depend on the properties of the wool (mean fibre diameter and length, fibre strength etc.), the construction of the fabric (yarn count, yarn twist, knit or weave structure etc.) and the wash test method (type of washing machine type, duration of test, wash liquor pH, temperature, salt concentration, pass/fail criteria etc.).
  • Shrink resistance is now generally regarded as, and for the purpose of the present invention shrink-resistance is defined, according to the International Wool Secretariat Test Method 31 in which a swatch is knitted from a 2/22 count yarn at a cover factor of 1.1 and relaxed for one ISO 7 A wash cycle followed by 5 ISO 5 A wash cycles in a Wascator front loading machine and shows less than 10% area shrinkage.
  • shrink-resistance in the older literature may now be regarded as poor shrink-resistance or not shrink-resistant.
  • Different methods of treatment of wool with a chemical such as PMS result in different effects (eg. amount of reaction, type of reaction, or where on the fibre reaction occurs) and this then influences the shrink-resistance and other properties.
  • Three general types of treatment can be considered - batch, continuous and semi-continuous (or pad/store), and in each type further variations are possible by changing the type of equipment used or the method of operation of the equipment.
  • a batch treatment the wool is left in a vessel for a period typically from 10 minutes to one hour and the chemicals are added at once or slowly.
  • a feature of batch treatments is the long reaction time which may allow diffusion of small molecules into the fibre.
  • the wool In continuous treatments the wool is rapidly run through a bowl containing a solution of the chemical then after squeezing the wool immediately passes into another bowl or a series of bowls containing water or other chemicals. Such continuous reactions are characterized by short reaction times, typically around 15 seconds and this tends to confine reactions to the fibre surface.
  • the semi-continuous or pad/store method the wool is first passed through a solution of chemicals in the nip of a horizontal pad mangle and then stored for 1 -5 minutes before passing through a series of bowls as in the continuous method. In this approach the reaction time is intermediate between that of continuous and batch treatments.
  • the pumping action ensures 5 an even treatment throughout the web of wool, whereas in backwashing bowls the outer surfaces of the web may undergo a greater extent of chemical reaction than the centre of the web. Further control can be effected on the extent of reaction and the treatment process, for example in the continuous method the speed at which the wool is transported through the bowls may be varied or the rate at which liquid is pumped through the web in suction drum bowls may be varied.
  • PMS is known to impart shrink-resistance to wool, eg. British Patents 692,258, 716,806 and 1,084,716 which describe batch, pad/store or continuous treatments with backwashing bowls, however the level of shrink resistance was low.
  • D.L. Connell in Deutschen Wollabasinstitutes Reports, Nol 114, 1995, page 183 provides an example of the low
  • PCT application WO 92/00412 also describes the addition of polymers to further enhance the shrink-resistance.
  • Polymers suitable for use in enhancing shrink resistance have been described as containing amino groups and having a backbone comprising carbon atoms, some of which may be replaced by nitrogen or oxygen atoms (eg. US Patent 3,811,835, European patents 414,377 and 315,477).
  • a particular advantage of the present invention is the ability to treat a web of wool slivers with weights greater than 30 ktex and fibre diameters greater than 18 micron, at a speed in excess of 8 metres/min.
  • the wool for the purposes of the present invention may be in the form of slivers which may or may not have been combed.
  • the method is applicable to card sliver as well as to tops.
  • Slivers subjected to continuous treatments typically have a weight above 15 ktex.
  • slivers of around 20 ktex are commonly used and it is well known with chlorination treatments that heavier slivers particularly above 30 ktex, obtain uneven treatment and the shrink-resistance is poor.
  • the ability to treat slivers in accordance with the present invention of 30 ktex or higher, such as 40 ktex substantially increases productivity.
  • the method of the present invention may be carried out in any apparatus suitable for continuously processing a web of wool slivers such that the web is capable of treatment with a solution.
  • any apparatus suitable for continuously processing a web of wool slivers such that the web is capable of treatment with a solution.
  • Other types of apparatus such as immersion bowls or by conveying the web through bowls or under sprays between two continuous perforated belts, may be used but are not as effective at imparting shrink resistance as suction drum bowls.
  • the residence time of each of the four stages designated (i), (ii), (iii) and (iv) are from about 10 to about 20 seconds, preferably about 15 seconds.
  • a suction drum having a diameter of about 500 millimetres which for a 1 metre wide drum would typically be in a bowl of volume between 400 and 600 L and solution would be pumped through the drum at a rate of about 2-4 bowl volumes/minute, typically 3.
  • These residence times correspond to all web speeds of in excess of 8 metres per minute.
  • the bowls will not all operate at the same speed.
  • the first bowl is slightly slower than the second which in turn operates at a slightly slower speed than the third and so.
  • the wet web tends to draft slightly, i.e., the web extends and the weight per unit length is slightly reduced. Consequently when a speed of say 8 metres/minute is quoted this speed refers to the speed of the wool web as it passes out of the last bowl.
  • the present invention makes it possible to operate at speeds hithertofore unattainable of 8 metres/minute or greater, and particularly in the range 10-12 metres/minute and still impart a high level of shrink- resistance.
  • a series of suction drum bowls are operated so that, as the wool web leaves each suction drum bowl the web passes through a series of squeeze rollers to prevent excess liquid being removed from the bowl and the liquid removed from the web by the squeeze rollers is allowed to flow back into the suction drum bowl.
  • wetting agents are particularly important in continuous treatments because there is only a short time available for reaction; for example if a dry wool sliver is run into a PMS solution as described in the prior art in a suction drum bowl operating from 5 to 15 metres/minute the treatment will be uneven since the centres of slivers will not have wet out completely during immersion. Consequently in continuous PMS treatments it is usual practice to add a wetting agent, to the PMS treatment solution.
  • the amount of non-ionic ethoxylated detergent used in stage (i) will be dependent upon the web if wool slivers, the type of non-ionic ethoxylated detergent, and the residence time of the wool slivers in the detergent solution.
  • concentration of non- ionic ethoxylated detergent in stage (i) is in the range of from 4-10 g/L, more preferably 5 g/L.
  • the temperature of stage (i) is preferably in the range of from 40-70 °C, more preferably 50 °C.
  • the non-ionic ethoxylated detergent may be any such detergent which is used as a standard scouring agent in the industry.
  • the non-ionic ethoxylated detergent is preferably an alkylene oxide, more preferably an ethylene oxide, derivative of a fatty alcohol or an alkylphenol.
  • Preferred detergents are derivatives of fatty alcohols having from ten to twenty carbon atoms or mixtures thereof or alkylphenols with alkyl groups having from seven to twelve carbon atoms reacted with from five to fifteen moles of ethylene oxide.
  • the preferred method, for use in stage (i) includes suction drum bowls but may also include other types of apparatus, including the Fleissner split-pad chlorinator, and the Kroy deep irnmersion chlorinator which are used commercially in continuous chlorination shrink-resist treatments for wool. These types of apparatus are readily adapted for treatment of the web with non-ionic ethoxylated detergents.
  • stage (i) such as into a suction drum bowl, containing the non-ionic ethoxylated detergent and a wet web leaves the bowl
  • the volume of liquid in the bowl will decrease with time. Additionally dirt and grease will build up in the bowl.
  • the rate of addition of detergent solution is in the range of from 2 to 10 times, the weight of the dry wool web entering the bowl in that given time most preferably from 5 to 8 times.
  • the permonosulfuric acid or salts thereof is preferably in aqueous solution obtained by dissolving the triple salt 2KHSO 5 .KHSO 4 .K 2 SO 4 in water; this triple salt is available commercially as Caroat (Degussa) or Oxone (DuPont). It is to be appreciated by those skilled in the art that solutions of the PMS triple salt could be replaced by solutions containing equivalent concentrations of pure permonosulfuric acid, or by solutions of the sodium salt of permonosulfuric acid adjusted to pH 2 with sulfuric acid.
  • the permonosulfonic acid may also conveniently be produced by the reaction of hydrogen peroxide with sulfuric acid.
  • the preferred method of the present invention in the second suction drum bowl uses a solution of the permonosulfuric acid or salts thereof at a concentration preferably in the range of from 20 to 60 g/L in water at a temperature preferably in the range of from 20 to 60 °C.
  • two separate suction drum bowls containing the solution of permonosulfuric acid or salts thereof are used in stage (ii).
  • the sulfite solution used in stage (iii) is preferably a solution of sodium sulfite at a concentration from 20-50 g/L and at a temperature from 20-50 °C.
  • the sulfite solution is preferably maintained at a pH in the range 8-10, such as by the addition of sodium carbonate or sodium hydroxide. It is to be appreciated by those skilled in the art that the sulfite solution could be prepared potassium sulfite or that solutions of sodium bisulfite, sodium metabisulfite or sulfur dioxide adjusted to pH 8-10 with alkali.
  • the aminofunctional polydimethylsiloxones for use in the present invention may have a linear or branched backbone and the aminofunctional groups may grouped together in blocks or randomly distributed along the polydimethylsiloxane backbone.
  • the aminofunctional groups are preferably in the separated from the silicon atoms of the backbone by three or more carbon atoms and may be primary, secondary or tertiary aliphatic amines or a mixture thereof.
  • suitable commercially available aminofunctional polydimethylsiloxanes include SM 8709 (Toray Dow-Corning) CT 45e and NP 1445e (Wacker Chemie), and JG4008A and AR4136A (Flexichem).
  • the arninofunctional polydimethyl siloxane may be in the form of an emulsion, dispersion or microemulsion, conveniently prepared with the aid of cationic, non-ionic or anionic emulsifiers, preferably at a concentration in the range of from 2 to 20 g/L of the aminofunctional polydimethyl siloxane and more preferably in the range of from 5 to 15 g/L.
  • the pH is maintained in the range of from 4 to 7.
  • rinse bowls can be placed between stages (i) and (ii) between stages (ii) and (iii) or between stages (iii) and (iv), and this may conveniently be done with any combination of between one and three rinse bowls.
  • rinse bowls can be placed between stages (i) and (ii) between stages (ii) and (iii) or between stages (iii) and (iv), and this may conveniently be done with any combination of between one and three rinse bowls.
  • the wool is passed around the surface of perforated cylindrical drums through which hot air is drawn.
  • stage (iv) of the present invention can be performed in a suction drum between the two stages of the dryer.
  • the wool can be dried between stages (iii) and (iv).
  • Two stage dryers allows another variant of present invention that the other materials that can be applied in stage (iv) may be sprayed onto the wool between the dryer stages.
  • Wool treated by the methods of the prevention was found to have a high level of shrink- resistance as measured according to IWS TM31 and discussed above, to have a soft handle, to have a whiter colour than the untreated wool, to dye in a similar manner to untreated wool (unlike wool treated with commercial cationic polymers such as Hercosett 250 (Hercules Inc.), to dye under pressure in top form without hardening, to dye such that the dyed wool has good rub-fastness, and had a reduced tendency to form pills. From the environmental point of view the methods of the present invention do not release AOX either during the treatment or in subsequent dyeing or finishing.
  • a sample of treated wool sliver was spun to a 2/71 tex yarn with 370 tpm singles and 213 tpm twofold twist which was knitted into a single jersey swatch with cover factor 1.1. Swatches were washed in a Wascator FOM 7 IMP machine according to the International Wool Secretariat Test Method 31. A 1 kg load of samples and polyester weighting squares are relaxed by washing with one 7 A wash cycle, measured washed for five 5 A wash cycles, measured again and the area shrinkage (abbreviated below to AS) is then calculated. An area shrinkage in excess of 10% is considered a failure (and is shown as F in the results below).
  • Experiments 1-4 demonstrate that the methods of the present invention are superior to those in which the wetting agent is not in a separate bowl at the start but is omitted or is added to the PMS bowl.
  • Experiments 5-7 demonstrate the importance of the preferred conditions in the pre- scour stage 1, while experiments 16-18 demonstrate the use of alternative non-ionic detergents in stage (i).
  • Experiments 8-1 1 demonstrate the shrink-resistance is lost one of the PMS bowls, the sulfite bowl or the silicone is omitted.
  • Experiments 12-14 demonstrate that the omission of the lubricant Selbana 4611 has no effect and that another silicone can be used.
  • the polymer Hercosett 250 which is extensively used on chlorinated wools, gives no shrink- resistance.
  • Example 2 This example uses the same conditions as experiment 1 of Example 1 but wools of different average fibre diameters and/or sliver weights were treated at different line speeds.
  • Example 3 This example uses a two stage dryer rather than the one stage dryer used in example 1. Between the two stages there is an additional suction drum bowl designated bowl 7. In the following experiments bowls 1 to 5 inclusive were the same as in experiment 1 example 1.
