Definitions

  • wool fibers used in the present invention means dandruff fibers obtained from sheep, goats, llamas, alpaca and similar animals.
  • Wool fibers are composed of aggregates of prosenchymatic cortex cells, which form the cortex inside the fibers, and flat cuticle cells, which form the surface layers.
  • the cuticle cells are scaly, and the top ends of these cells are overlapping edges to protect the cortex.
  • the surface layer of wool fibers extends inwards from the outside and has an exocuticle, an endocuticle and an epicuticle surrounding this cuticle.
  • Polar groups are contained in large quantities in the endocuticle.
  • the endocuticle on the inside of the marginal areas of the cuticular cells forms a layer that swells slightly when water is absorbed and can easily be influenced by it.
  • the method for modifying wool fibers to increase their quality according to the present invention is to locally chlorinate edge areas which run in the form of scales on the surfaces of the wool fibers, to dissolve and remove the chlorinated edge areas by the reduction treatment in order to remove the surfaces smooth the wool fibers and reinforce the smoothed surfaces to obtain high quality wool fibers that have a smooth surface and good durability.
  • a method according to the preamble of claim 1 is already known (FR-A-1 271 349).
  • the wool fibers are immersed in an oxidation bath that contains chloride, hypochlorite and a cyanuric acid salt and has a neutral or weakly alkaline pH. After removal from the oxidation bath, the wool is washed, treated with a pyrosulfite solution for dechlorination, washed again and dried.
  • the known method is intended to prevent the wool from felting and shrinking.
  • the invention achieves the object of specifying a method for modifying wool fibers in order to increase their quality, in which the edge regions on the surfaces of the wool fibers are removed, in order to modify wool fibers with a smooth surface and good Get a grip.
  • the present invention provides a modification technique by which numerous properties of the wool fibers, such as gloss, softness, shrink resistance and dyeability, can be improved without degrading the basic properties of the starting wool fibers. For example, alpaca lamb fibers, merino wool fibers and teeswater wool fibers are modified into fine mohair-like fibers or cashmere-like fibers or mohair-like fibers according to the newly developed technique of the present invention.
  • a wool fiber material is first immersed in a saturated solution of a neutral salt, such as sodium chloride or Glauber's salt, which contains an acid such as hydrochloric acid, sulfuric acid, acetic acid, formic acid, phosphoric acid, monochloroacetic acid or dichloroacetic acid. Since the surface of the wool fiber is very water-repellent, a saturated solution is such a strong one Electrolytes are unable to dissolve the surface of the wool fiber. On the inside of the edge areas of the scales of the wool fiber, however, there is the endocuticular area which contains large amounts of polar groups and to which water is incorporated in the normal state, and the acid is contained in this area in a state dissolved in this water.
  • a neutral salt such as sodium chloride or Glauber's salt
  • the wool fiber is then immersed in a saturated solution of a neutral salt or in water, the saturated solution or water containing sodium hypochlorite, sodium chlorite or chlorocyanuric acid salt.
  • a neutral salt or in water containing sodium hypochlorite, sodium chlorite or chlorocyanuric acid salt.
  • sodium hypochlorite which is supplied in a strongly alkaline state with a pH of 12 for stabilization
  • an acid is added to neutralize just before immersion and the solution is used in the neutral state; however, this prior neutralization is not required in the case of the chlorocyanate salt, which is dissolved in water to form a neutral solution.
  • the wool fiber When the wool fiber is so immersed in the solution of a chlorinating agent such as sodium hypochlorite, sodium chlorite or chlorocyanuric acid salt, the chlorine of the chlorinating agent is activated in the acidic areas to bring about chlorination, whereas in other areas no chlorination is initiated because these areas of the saturated solution of sodium chloride or Glauber's salt. Then the wool fiber is immersed in water, causing the chlorinated area to swell. When the wool fiber is immersed in water containing the chlorinating agent, chlorination and swelling are accelerated simultaneously in the acidic region. In this case, the response is relatively stormy or vigorous.
  • a chlorinating agent such as sodium hypochlorite, sodium chlorite or chlorocyanuric acid salt
  • the wool fiber is treated with an alkaline solution containing a reducing agent such as sodium pyrosulfite and ammonia or the like, thereby reducing and dissolving the non-chlorinated remaining areas to smooth the surface of the wool fiber.
  • a reducing agent such as sodium pyrosulfite and ammonia or the like
  • the required amount of an acid is incorporated into the inside of the projection of the scaly edge areas of the wool fibers, where water is absorbed very uniformly, while the other areas are controlled by a saturated solution of a neutral salt, so that the acid is removed, to penetrate into these areas, whereupon chlorine is activated by the incorporated acid in a chlorination bath and the chlorination takes place only in precisely limited areas.
  • the present invention provides a chlorination process that eliminates all of the disadvantages of the conventional process.
  • the surfaces of the wool fibers are smoothed.
  • the wool fibers are thus modified in accordance with the present invention, and their grade of quality is increased by this specific method.
  • NaCIO sodium chloride
  • the acid incorporated in the surface layer causes chlorination, and the reaction proceeds very gradually in such a state that the chlorine gas hardly leaks from the surface layer.
  • the chlorination proceeds relatively vigorously through the acid contained in the wool fiber to form chlorine.
  • This treatment dissolves 95 to 100% of the edge area and the surface of the wool fiber is smoothed.
  • the wool fiber is then treated for 3 to 6 minutes in a solution which contains 3-10 ml / i formalin (37% solution), has a pH adjusted to a neutral value and is kept at 50-90 ° C., to reinforce the surface of the wool fiber, after which the wool fiber thus treated is washed. This completes the method according to the present invention.
  • the Lincoln wool hair is immersed in the above-mentioned solution containing sodium chloride and hydrochloric acid for six minutes. Then the wool fiber is squeezed out with a liquid removal ratio of almost 100% and immersed in the following solution, the pH of which is adjusted to 6.5 by adding hydrochloric acid:
  • the solution is circulated at 20-22 ° C for 10 minutes.
  • the liquid is removed, the edge area is swollen with cold water, and the treated wool fiber is washed with water.
  • the wool fiber is then treated in the following solution at 25 ° C. for 3 minutes:
  • the liquid is removed and the treated wool is washed with warm water kept at 35 ° C. Then the wool fiber is treated at 80 ° C for 30 minutes in the following solution, the pH of which is adjusted to 5 by adding acetic acid:
  • the treated wool fiber is washed with water and dried.
  • the treatment method according to the invention is thus completed.
  • the wool hair treated in this way has a wonderful shine, which is similar to that of mohair, and a very soft feel. When viewed with a microscope, the surface condition can hardly be distinguished from that of mohair.
  • Wool fibers previously used for blended products with mohair wool can be modified according to the present invention, and high quality wool fibers can be obtained which result in loop yarns, knitted fabrics and knitwear comparable to those made exclusively from mohair wool consist.
