Definitions

  • This invention relates to the use of a compound undergoing photo yellowing for cancelling out the photo bleaching which wool and other similar natural fibres undergo when the wool and/or natural fibres are first exposed to sunlight, such as behind glass.
  • Photobleaching (sometimes called “first fade” or “red fade”) is seen as a rapid but limited on-tone fading of the natural creamy yellow of wool.
  • Yellowness induced from processing eg, dry-heat, hydrothermal or alkali yellowing is also photobleachable.
  • the bulk of the photobleaching occurs within 5-10 hours of the wool being exposed behind glass to midsummer sunlight and continues at a slower rate for another 40-50 hours.
  • the colour change caused by photobleaching is a cause of a significant number of consumer complaints particularly in the case of carpets. It is noticeable when furniture is moved revealing a colour difference between the areas of carpet which have been exposed to sunlight and those which have been unexposed.
  • the primary object of the present invention is to reduce or prevent this initial colour change in wool or wool blend furnishings which occurs on exposure to sunlight thus eliminating consumer complaints due to this cause.
  • a chemical compound for treating natural fibres for cancelling out the photo bleaching thereof the chemical compound undergoing photoyellowing at a similar rate to the rate at which the natural fibres undergo photobleaching, the chemical compound being applied in such an amount that the change in yellowness of the treated fibres, when exposed to sunlight, such as behind glass, is reduced or prevented in comparison to untreated fibres.
  • the preferred class of chemical compounds are known industrially as syntans and may consist of condensation products of aromatic sulphones and/or sulphonic acids.
  • Yellowness values were measured using a Hunterlab Spectrocolorimeter using a 2° observer and illuminant C before and after exposure to 40 hours midsummer sunlight (Christchurch, NZ).
  • the treatment was applied during the dyeing of a commercial production yarn batch of two tonnes.
  • the dyeing was carried out in a longclose single stick hank dyeing machine using Sandolan MF dyes (Sandoz) at 0.8%.
  • Sandolan MF dyes Sandolan MF dyes
  • HAS hydroylammonium sulphate
  • HAS hydroylammonium sulphate
  • the wool blend had a Y-Z value of 4.6. Samples from this treated batch as well as untreated samples from a previously dyed batch and the untreated, undyed wool were exposed behind 2 mm picture glass to mid-summer sunlight (Christchurch, NZ).
  • the treatment was applied during commercial loose stock dyeing to a 2.8 tonne batch of wool with an initial Y-Z value of 3.0.
  • Dyeings consisted of 12 lots each of 235 kg dyed with 2:1 premetallised dyes to a light beige shade (0.013% dye).
  • the treatment was applied with other dyeing auxiliaries included 1 % HAS.
  • the level of the aromatic sulphonic acid was 0.4%.
  • the 12 dyeings were blended and processed into yarn which received a scour in a 5 bowl tape scour. This was followed by another 5 bowl chemical setting treatment using 10 g/L of sodium metabisulphite.
  • the yarn was similarly exposed behind 2 mm picture glass to mid-summer sunlight for 40 hours. An untreated control sample and an undyed/untreated wool sample were also exposed.
  • This example shows the treatment is fast to tapescouring and chemical setting if applied during dyeing.
  • the wool can be treated during scouring, at the dyeing stage or on a continuous carpet processing line.
  • the treatment can be applied to loose wool, wool yarn, wool fabric or carpet.
  • the level of compound applied depends on the initial yellowness of the wool and the dyestuffs used but can be adjusted so that there is little or no colour change due to photobleaching behind glass.
  • HAS hydroxylammonium sulphate

Claims (8)

  1. Utilisation d'un composé subissant un photojaunissement, destinée à supprimer le photoblanchiment de fibres naturelles, caractérisée en ce que le composé subit un photojaunissement à un taux similaire au taux de photoblanchiment des fibres naturelles, et le composé est appliqué dans une quantité telle que la modification du jaunissement des fibres traitées, lorsqu'elles sont exposées au soleil, est réduite ou empêchée en comparaison à des fibres non traitées.
  2. Utilisation d'un composé selon la revendication 1, caractérisée en ce que le composé chimique comprend un produit de condensation de sulfones aromatiques.
  3. Utilisation d'un composé selon la revendication 1, caractérisée en ce que le composé chimique comprend un produit de condensation de l'acide sulfonique.
  4. Utilisation d'un composé selon la revendication 1, caractérisée en ce que le composé chimique comprend un azurant, un agent de tannage, ou des acides sulfoniques aromatiques.
  5. Utilisation d'un composé selon l'une quelconque des revendications précédentes, caractérisée en ce que le composé chimique est appliqué lors du dessuintage, de la teinture ou du traitement des fibres naturelles.
  6. Utilisation d'un composé selon l'une quelconque des revendications précédentes, caractérisée en ce que la fibre naturelle est la laine.
  7. Utilisation d'un composé selon la revendication 6, caractérisée en ce que le composé chimique est appliqué à de la laine en vrac, du fil de laine, un tissu ou un tapis de laine.
  8. Utilisation d'un composé selon l'une quelconque des revendications précédentes, caractérisée en ce que la quantité de composé chimique appliquée sur les fibres naturelles dépend du jaunissement initial de la laine.
