Definitions

  • the present invention relates to a process for garment dyeing of an article comprising a microfibrous non woven fabric .
  • Microfibrous non woven fabrics made from synthetic polymer microfibers, generally polyester or polyamide combined with a polyurethane matrix, are well known in the art. Such fabrics have the appearance of natural leather and are often even superior to it as regards some characteristics, such as feel, lightness, and fastness to light and atmospheric pollutants (in particular nitrogen oxides) . Such microfibrous non woven fabrics are thus of particularly fine quality and are widely used in the clothing and interior design industries, and for the interior upholstery of cars, boats and other means of transport.
  • microfibrous non woven fabric can be coupled, if necessary, with suitable substrates, such as canvas, knitted fabric or expanded plastic material, in order to impart the required mechanical strength and rigidity to the product.
  • suitable substrates such as canvas, knitted fabric or expanded plastic material
  • the garment dyeing process entails directly immersing the finished garment, manufactured from raw or so-called "ready-to-dye” fabrics, i.e. fabrics subjected to preliminary purging (elimination of oil or sizing solutions), bleaching, heat setting or other treatments, in the dyeing bath, in special machines.
  • This process was developed in particular for dyeing natural fibres such as wool and cotton, using, therefore, "open” dyeing machines, i.e. machines operating at atmospheric pressure and thus with a dyeing bath temperature lower than 100 °C.
  • the Applicant set itself the objective of realizing articles comprising a garment-dyed microfibrous non woven fabric, which exhibits aesthetic properties and a "feel" typical of microfiber non woven fabrics, and at the same time high colour fastness to dry cleaning or wet washing, and under prolonged exposure to light and/or sweat.
  • the Applicant has ascertained that directly subjecting an article comprising a microfibrous non woven fabric to a garment dyeing process with a bath temperature of over 100°C does not provide satisfactory results, in particular as regards the aesthetic properties, "feel” and colour fastness.
  • the article turns out to have an excessively rigid "feel", a flat (non-mottled) appearance, and shows an aesthetically inferior surface due to the evident presence of dirt and fluff.
  • the colour fastness is inadequate to satisfy the most common quality standards, in particular after repeated washing and contact with sweat.
  • garment dyeing a article comprising a microfibrous non woven fabric is capable of providing results meeting the above-described objectives if the microfibrous non woven fabric is first subjected to a pre-treatment with an aqueous solution containing dyeing auxiliaries devoid of dyes, at a temperature of from 100°C to 140°C, subsequent washing in order to remove the dyeing auxiliaries, manufacture of the article to be dyed and then the dyeing process itself at a temperature of from 100°C to 140°C, to be followed by at least a "stripping" step in order to remove the dye not fixed into the material.
  • the present invention thus relates to a process for garment dyeing of an article comprising a microfibrous non woven fabric, which comprises:
  • a dyeing bath comprising at least one dye and dyeing auxiliaries, at a temperature of from 100°C to 140°C;
  • this is preferably carried out by immersion in an aqueous solution containing dyeing auxiliaries at a temperature of from 100°C to 140°C, preferably from 110°C a 130°C.
  • the immersion time can vary within wide limits, and generally from 1 to 6 hours, more preferably from 3 to 5 hours with a maintenance time at the maximum temperature of from 30 to 90 minutes, more preferably from 45 to 75 min.
  • the pre-treatment step is generally carried out in a machine such as to impose stresses of a thermal- mechanical type on the raw material, in particular via agitation of the bath and contact of the piece with the nozzles normally present in jet dyeing machines.
  • the dyeing auxiliaries comprise an acid-base pair which acts as a buffer, preferably selected from among: a carboxylic acid/carboxylic salt mixture (e.g. an acetic acid/alkali metal acetate mixture, or a citric acid/alkali metal citrate mixture) .
  • the dyeing auxiliaries further comprise at least one ionic or non-ionic surfactant, e.g. polyglycols or modified polyalcohols , fatty amine esters, naphthalene sulfonic acids, fatty acids or derivates thereof.
  • the aqueous solution containing dyeing auxiliaries has a pH value ranging from 4.0 to 5.5, preferably from 4.4 to 5.0.
  • the dyeing auxiliaries are present in concentrations greater than 2 g/1 relative to the volume of the dyeing bath.
  • the subsequent washing step has the purpose of removing the dyeing auxiliaries in a substantially complete manner, and can be carried out with water, in particular water at room temperature, for example by overflow rinsing .
  • the non woven fabric thus pre-treated is generally subjected to drying.
  • this is carried out like the normal manufacture of an article of clothing, but with particular attention being paid to the tension with which the seams are sewn to prevent defects from occurring during the subsequent dyeing of the article thus realized, due either to a different shrinkage of the materials themselves and of the seams, with the formation of creases or folds, or poor penetration of the dye into the stitches, thus generating characteristic defects of inhomogeneous dyeing .
  • the dyeing step is generally carried out by immersing the manufactured article in a dyeing bath comprising at least one dye and dyeing auxiliaries, at a temperature of from 100°C to 140°C, preferably from 110°C to 130°C.
  • a dyeing bath comprising at least one dye and dyeing auxiliaries, at a temperature of from 100°C to 140°C, preferably from 110°C to 130°C.
  • the dyeing auxiliaries these can be selected from among the ones indicated above for the pre- treatment step.
  • the dyes these can be selected from the class of disperse dyes, e.g. azoic dyes, anthraquinone dyes, aminoketone or quinophthalone dyes, or leuco dyes.
  • the dyeing step is carried out in a garment dyeing machine having a closed bath, which makes it possible to dye at a pressure higher than the atmospheric pressure and with a bath temperature of up to 140°C, and at the same time to ricirculate the dyeing solution and if necessary reinject it into the bath via a high-pressure jet.
  • the dyeing step is carried out with a bath ratio ranging from 1:2 to 1:30, preferably from 1:4 and 1:20.
  • Said step preferably envisages a maintenance time at the maximum temperature of from 30 to 90 min, preferably from 45 to 60 min.
  • the basket speed is generally set at at least 20 rpm.
  • the subsequent stripping step mainly having the purpose of removing the non-fixed dye, is preferably carried out by treating the dyed article with a basic solution comprising at least one reducing agent.
  • a basic solution comprising at least one reducing agent.
  • the latter can be selected between, for example, sodium hydrosulfite and sulfinic acid derivatives.
  • the basic solution preferably has a pH value greater than 8, more preferably greater than 10. Such pH values can be obtained by adding an inorganic base, in particular an alkali metal hydroxide, for example an aqueous solution of NaOH and/or KOH.
  • the basic solution preferably includes at least one surfactant, preferably of the class of organic phosphorous compounds or mixtures of neutralized organic acids.
  • the stripping step is preferably carried out at a temperature of from 50°C to 100°C, more preferably from 70°c to 90°C.
  • the stripping step preferably has an overall duration of from 90 to 360 minutes, more preferably from 100 to 240 minutes, and can be subdivided if necessary into a plurality of sub-steps so as to obtain a better removal of the non-fixed dye. Between one sub-step and another, the basic solution is drained and replaced with fresh solution. It should be noted that in the stripping step, unlike the actual dyeing step, it is preferable not to carry out recirculation of the solution with air injection (for example with high-pressure jets), since the solution itself would tend to become exhausted more quickly, and it is thus advantageous to replace it cyclically with fresh solution. In fact, the Applicant believes that injecting air into the stripping bath would have the effect of accelerating the process of degradation of the reducing agent, which would react prevalently with the air rather than with the excess dyes.
  • the dyed article is washed and dried according to known techniques.
  • the raw microfibrous non woven fabric this can be produced according to techniques well known in the art, for example as described in patents EP 0 584 511, US 3 716 614, US 3 531 368 and EP 1 431 448, all in the Applicant's name.
  • the process generally envisages a step of producing of a flock fibre formed from microfibers of polyester, in particular polyethylene terephthalate, having an extremely fine titre, generally from 0.01 to 0.4 deniers, preferably from 0.08 to 0.15 deniers, coated with a texturing sheath, generally formed from polystyrene, a styrene copolymer, a copolyester or a polyvinyl alcohol.
  • the textured flock fibre generally has titre of from 1.4 to 10 deniers, preferably from 2.5 to 6 deniers, a length of from 30 to 150 mm, a stretching ratio of from 2/1 to 5/1 and curling of from 4 to 15 waves per centimetre.
  • the textured flock fibre generally comprises from 30 to 90% of polyester by weight and 10 to 70% of texturing sheath by weight.
  • the flock fibre thus produced is then used to prepare, according to known techniques, a raw felt, which is then subjected to needle punching so as to obtain a needle- punched felt generally having a density of from 0.15 to 0.35 g/cm 3 .
  • the needle-punched felt is then immersed in an aqueous solution of polyvinyl alcohol and then, after drying, in a solvent capable of solubilizing the matrix in a substantially complete manner.
  • the resulting product is subjected to drying so as to obtain the non woven microfiber fabric, which is impregnated, by immersion in a solution or dispersion, with an elastomeric matrix, preferably polyurethane .
  • the polyurethane generally consists of soft segments and hard segments.
  • the soft segments generally have an average molecular weight ranging from 500 to 5000, preferably 600 to 2000, and can be selected from among, for example:
