Definitions
- the invention relates to a method for chlorine-free antifelting of wool.
- Wool is a protein fiber with a complex structure. Due to the growth and function of the hair, the fiber core (cortex) is covered by a relatively hydrophobic layer. This outer layer is called the cuticle and consists of a roof tile superimposed scales. As a result of this outer scale structure, a wool hair has a different mechanical frictional resistance depending on the fiber direction or direction of the flake structure.
- the sawtooth-like structure allows easy shifting in one direction while in the other direction the fibers tend to catch. This effect leads to a compaction of the textile wool structure, especially when exposed to moisture, temperature and mechanics; one speaks of felting. This process can be exploited in the targeted densification of nonwovens, fabrics and knitted fabrics to felts / W alkstoffen / loden.
- Chlor-Hercosett process uses a multi-stage treatment of wool fibers with chlorine, followed by a reductive treatment with sulfite and a deposition of polymeric substances.
- a "masking" of the scale structure by oxidative removal as a result of chlorine treatment, by reductive separation of products by the sulfite treatment (sulfitolysis) and by the deposition of polymer films is discussed.
- the treated products have excellent shrinkage values even after a multiple
- the working technique has serious disadvantages, which result from the use of chlorine as a treatment agent
- the process is carried out at room temperature, caused by the action of chlorine Critical Wastewater Content Substances (AOX, adsorbable organic halogen compounds) that can be reduced by optimization but which are unavoidable and in any case released from the process in high concentrations.
- AOX adsorbable organic halogen compounds
- hypochlorite or other chlorine-releasing compounds such as Na-dichloroisocyanurate (NaDCC).
- Na-dichloroisocyanurate Na-dichloroisocyanurate
- all of these methods share the disadvantage of the formation and release of the AOX products.
- the use of chlorine-free oxidants to substitute the chlorine compounds has been extensively studied.
- the use of mixtures of permanganate and hypochlorite has been described.
- potassium permanganate, peracetic acid, organic peroxides and inorganic peroxides, ozone as an oxidizing agent has been described.
- the use of plasma treatments or the application of proteolytic enzymes has been researched and described.
- these processes consist of an oxidative treatment with a solution containing peroxomonosulfate, followed by a reductive treatment. Frequently, a post-treatment with polymer is also described.
- the methods differ in the nature of the combination of the different methods and, accordingly, in the results resulting from the treatment.
- WO 92/00412 A1 describes a process for continuous oxidative felt-release treatment in which a mixture of hydrogen peroxide and potassium peroxo mono-sulfate are used for the treatment of wool by a squeeze application. After a short reaction time of 1 min, the wool is treated directly, without intermediate rinsing in a sulfite solution and provided after further rinsing with a polymer deposition. However, too high a washing shrinkage is observed.
- WO 93/13260 A shows a discontinuous treatment process of wool, since the pattern pieces are always inserted into treatment solutions. Apart from the impregnation step in Application Example 3, a stepwise treatment is provided for the remaining steps.
- EP 0 356 950 describes a batch process for treating wool knits.

- a padder capable of applying between 70% and 150% liquor is usually used, in a preferred form the device is adjusted so that the constant application rates are between 75% and 125% of net weight the wool in the reaction section b) are passed. In a particularly preferred form, the order is between 90% and 110%. Also, a liquor order by spraying, drops or other known fleet application techniques is possible.
- the speed of the continuous plant results from the generally known technical process parameters of the construction, for example length of the residence section in a treatment compartment and is in conventional engineering constructions between 5 - 12 m / min, which corresponds to a treatment time per machine compartment of about 10 s to 30 s.
- step b) allowing the solution to act on the wool to complete the oxidation process, the wool impregnated with the oxidizing agent solution is deposited on a suitable tray so that uniform temperature adjustment is possible and no sagging of the treating solution occurs.
