Definitions

  • the invention relates to a method for crimping synthetic hair from synthetic monofilament fibers in a warm, humid atmosphere for the production of hair replacement parts, in which the synthetic hair is treated at a temperature above its plastic deformation point.
  • Patent application no. DE-A-34 31 886.0-26 dated September 17, 1985 has recorded a way in which thermally resistant monofilament synthetic fibers can be adapted to natural hair in terms of its external appearance, that is to say in its glossy appearance.
  • This hair replacement material treated in this way can only be insufficiently processed into hairstyles with the previously used crimping methods.
  • Hot air treatments with the well-known hair dryer resulted in excessively long production times, and the handle of the material became hard and brittle. Treatment in boiling water does not sufficiently stabilize the shape of the waves and frills.
  • polyester monofilament hair must be broken down very strongly before dyeing in order to get a hair-like appearance. This is achieved by appropriately breaking down more than 30% of the fiber substance, preferably by hydrolysis. Such a strong change in the fiber suggests that the shape of the fiber is also significantly impaired in its long-term stability.
  • British Patent 664921 also points out that strong fiber degradation also leads to high strength losses. It had to be assumed that the mechanical influences, such as those present when washing and combing synthetic hair, are only possible through a subsequent heat setting which is optimal for polyester fiber at temperatures of 185 ° C. and more, and under at least slight tension after the surface treatment , permanently survives. To date, technology has assumed that permanent deformation on polyester fibers can only be achieved with hot air temperatures above 185 ° C. You would have to expect that from a polyester monofilament fiber that has been broken down by more than 30%.
  • polyester filament becomes brittle with increasing temperature and the sublimation of the dyes increases with increasing temperature, so that the coloring suffers.
  • polyacrylic fibers are crimped in a warm, moist atmosphere at temperatures of 55 to 80 ° C., temperatures outside this range being considered unsuitable. It is also recommended to use a humidity atmosphere of less than 100%.
  • the synthetic hair consisting of monofilament fibers is crimped at the specified higher temperatures in a pressurized steam atmosphere.
  • Steam conditioning of polyamide threads is also known from US Pat. No. 3,595,952 in order to improve their knot strength.
  • the polyamide thread is drawn through a saturated water vapor atmosphere within a very short period of 10 milliseconds to 5 seconds.
  • the goal of a smooth, knot-resistant thread is in contrast to the permanent crimping of monofilament fibers aimed at according to the invention.
  • the invention has for its object to curl monofilament fibers for a long time without embrittlement and disadvantageous sublimation of the dyes used for dyeing.
  • a particularly preferred design is that synthetic hair made of synthetic monofilament fibers, in particular polyester monofilament fibers, is mixed with a moisture-retaining agent at temperatures of 130 ° to 180 ° C. and crimped with hot air.
  • Monofilament fibers made of polyamide, polyurethane, polypropylene and especially polyester are preferred as synthetic hair.
  • the synthetic hair is treated with chemicals which act on the synthetic hair during the subsequent steam treatment.
  • the synthetic hair is first shaped with hot air without the addition of steam, in order to then be permanently fixed with the subsequent steam treatment.
  • a treatment with superheated steam is also possible, but due to the low moisture content of the steam, the fiber becomes brittle as the temperature increases.
  • Such a state diagram for vapors is characterized by the limit curves and the constant steam content curves in the wet steam area. All boiling points are on the boiling line and all saturated steam points are on the upper dew line. The two limit curves merge into one another at the critical point.
  • the boiling line separates the liquid area from the wet steam area
  • the dew line separates the wet steam area from the hot steam area. In the area between the boiling line and the dew line, all steam states are the preferred treatment agents for the hair fiber to be converted here.
  • the autoclave for treating the synthetic hair 15 consists of a boiler 2, at the lower part of which a steam feed line 7 opens, which is supplied with steam by a steam generator 1, not shown.
  • the steam feed line 7 opens into a pipe 19 arranged in the boiler 2 and provided with radial bores, on which the synthetic hair 15 is applied in the form of a coil.
  • the steam flowing through the bores 14 radially passes through the synthetic hair 15 in the direction of the arrow 13 and at the same time also treats the synthetic hair 15 from the outside.
  • the boiler 2 is connected to a cover 3 by means of a screw connection 4 and a water inflow 5 also opens into the boiler and a water outlet 6 starts at the bottom.
  • a vent 8 On the boiler wall a vent 8 as well as a thermometer 11 and a manometer 12 are also arranged.
  • the lid is provided with a steam tap 9 and a safety valve 10.
  • FIG. 2 shows, as a possible exemplary embodiment, the treatment of the synthetic hair 15 applied as a wrap on the tube 19 with a steam-saturated hot air stream.
  • a blower 16 generates a hot air stream, to which a steam stream 17 is mixed by a steam generator.
  • the synthetic hair 15 and the tube 19 are surrounded on the outside by an air and water vapor permeable sheathing 18, so that the steam generated in this way only flows slowly into the environment.
  • the synthetic hair 15 can also be moistened beforehand with water or a water-chemical mixture.
  • the chemicals described above can be added to the steam generator 1, 17 in order to achieve an additional chemical treatment of the synthetic hair 15 in addition to the steam treatment.
  • this also results in surface finishing and possibly also coloring.
  • a synthetic hair is used which has been mechanically or chemically degraded by at least 30% by weight.
  • moisture-retaining agents on the hair material makes it possible to carry out the crimping with hot air at temperatures lower than 180 ° C.
  • the moisture-retaining preparations can be designed both as a dispersion and as an emulsion, these agents binding 0.1 to 4% of water, based on the fiber weight.
  • the shaping takes place at hot air temperatures from 130 ° C., preferably at 150 ° to 180 ° C., in particular 150 ° to 160 ° C.
  • the dyes listed below can be used to dye the synthetic hair fibers, the dyeing not being damaged during the subsequent crimping treatment using moisturizing agents and hot air at up to 180 ° C.
  • the dyes mentioned sublimate so little at temperatures below 180 ° C that sufficient fastness to washing is ensured for hair parts.
  • color uniformity with different light sources such as. B. daylight, standard light, evening light
  • the dyes mentioned are particularly well suited especially in combinations for dyeing hair pieces made of polyester monofilament material. This has resulted in extensive dyeing tests and tests. If one were to treat the same dyes with hot air above 180 ° C, there would be considerable color shifts and, with strong colors, considerable bleeding during subsequent washing, which would make the use of the material for hairpieces impossible.
  • the synthetic fiber starting material is degraded by alkalization with caustic alkali lye by 30 to 40% by weight, so that the fiber is roughened, then washed, neutralized, rinsed, dried and dyed.
  • the dyeing is preferably carried out at 130 ° to 135 ° C under positive pressure.
  • the synthetic hair coming from the dye bath is rinsed and treated with a moisture-retaining agent in dispersion or emulsion.
  • a means is preferred that can be applied by rinsing in the bath, spraying or other application methods.
  • the fiber treated in this way is dried so that a residual moisture content of preferably 0.1 to 4% by weight of water remains on the fiber. Then the crimping takes place by means of heat conversion by means of hot air at temperatures up to 180 ° C.
  • the treatment with hot air takes place in the range of about 10 to 60 minutes.
  • the hair is then cooled in the sheath.
  • the hot air treatment can be carried out at relatively low temperatures because the hair has previously been chemically roughened by the alkali treatment and is therefore particularly easily accessible for shaping, and the embrittlement of the hair is avoided by the use of the humectant.
  • the finished curled hair can be treated further, e.g. B. by applying plasticizers and / or heat protection agents, for. B. aluminum salts.
  • the advantages of the invention are, therefore, that crimping of the synthetic hair is possible without embrittlement and that excellent dyeability and color stability are achieved, since the degraded, in particular alkalized, fiber absorbs and maintains the dyes very well and low forming temperatures are used.
  • Another embodiment of the present invention provides for the use of carriers.
  • the use of these carriers has the advantage that the polyester material can be colored and formed even at low temperatures, namely at cooking temperatures.
  • Examples of such carriers are orthophenylphenol, oxycarboxylic acid methyl ester, chlorobenzene compounds and other compounds which are known as so-called carriers.
