Definitions

  • This invention relates to improvements in the treatment of fibres, yarns or fabrics, particularly for delustrlng natural silk, artificial silk of all types including cellulose esters or ethers or regenerated cellulose such as viscose silk, and has for its object to provide a new or improved process for treating such material or for weighting and/or delustring natural, silk, linen or other materials.
  • Further objects of the invention are to avoid waste of reagents, to improve control, to allow higher concentrations of reagents to be employed and to obtain pattern eifects of a very varied character.
  • the invention is a continuation in part of our application No. 93,232.
  • the textile material is treated with the ingredients in two phases or stages. 1. e., with some of the ingredients in one fluid, either liquid or gaseous, and with the remaining ingredients in another fluid.
  • two diiferent liquid baths may be employed for successive treatment of the textile material.
  • One bath may contain a solution of two of the ingredients and a second bath the third, but if desired the first bath may contain some proportion of all the ingredients and the second bath the requisite proportion of on or more of them to effect rapid precipitation.
  • the precipitation of methylene urea is to some extent a time reaction and this is capable of more exact control in the case of the two-bath process.
  • the two-bath process it is possible to impregnate with the urea say and then apply the printing technique, plain resists, coloured resists, etc., before treating in the second bath which produces the local matt effect where desired.
  • This offers much more scope for the contrast of matt 1 components thereof and then bringing about precipitation of an insoluble product from the solution.
  • the material is impregnated with the solution containing a precipitant in sufiicient quantity to form on the textile material, after sulficient time of contact, a precipitate substantially fast to washing.
  • the material impregnated with the solution may alternatively be brought into contact with a precipitant such as an acid.
  • the material may be first treated with a precipitant such as an acid and then impregnated with the urea-formaldehyde solution.
  • the textile material may be treated with the components of a synthetic condensation product, separately and in any desired sequence, but it is preferred to impregnate with urea and formaldehyde simultaneously.
  • the impregnation is performed without materially distorting the materials.
  • Fibres, yarns or fabrics may be treated by the process and the material so treated will withstand washing without regaining its lustre.
  • the treated materials can be dyed.
  • Cellulosic materials treated by the present process will, withstand the mercerisation operation, and'can also be dyed with acid dyes.
  • Example 1 Urea I m 60 Formaldehyde (neutral 40% solution) cc 100 Water ems 100 j 3
  • Example 2 Urea gms Formaldehyde (neutral 40% solution) cc 100 Water gms 100 are mixed together without any heating, and the fabric, yarn or fibre in the form of silver or roving' well wetted with a solution, squeezed and then subjected to acid vapour until the delustring has occurred, then well washed'with soap and soda ash solution together with an oil, and finally washed and dried as in Example 1.
  • Example 3 Urea gms-- 100 Formaldehyde (neutral 40% solution) cc 200 are refluxed with 3% 'NHiOH (sp. gr. .880) for 3 mins. at the boil, cooled, 300 cc. water added and acidified with /2 to 1% tartaric acid. Fabric, yarns or fibres are immersed in this solution passed' through a mangle and :allowed to stand until the delustring'has taken place, and finally washed and dried as in Example 1.
  • Example 4 60 gms. urea are dissolved in 100 s, 0 maldehyde (solution 40%). A natural silk fabric is run through this solution and squeezed through rollers to ensure even penetration. The cloth is then passed quickly through 4% hydrochloric acid (spec. grav. 1.02) and the reaction allowed to proceed until precipitation takes place. The amount of weighting obtained will depend on the amount of liquor left on the cloth, on the nature of the cloth to be treated, on the time for which precipitation is allowed to take place and on the nature of the catalyst. After precipitation has taken place the fabric is well washed with soap and soda ash and oil, then washed in water and finally dried.
  • the whole process can then be repeatedly performed until the. requisite increase in weight is obtained.
  • the suitably thickened urea-formaldehyde solution may be applied by direct printing followed by precipitation; selected areas may be treated with a suitable resist (e. g., with the ethanolamines and other bases or with known resists and then the delustring process applied, or selected areas of the delustred material may have the lustre restored by discharging (printing with a thickened acid) and steaming, followed by washing).
  • the patterned fabric may be dyed or dyes may be incorporated in the resist.
  • Example 5 oured efiects can thus be obtained on a matt ground.
  • Example 6 4ll-over delustred efiect 25 lbs. of urea was dissolved in 10 gals. of water and 3 qts. of glycerine added. An all-viscose satin cloth was impregnated with this solution and excess liquid squeezed off by passing it between the bowls of a two-bowl mangle adjusted so as to leave a quantity of liquor on the cloth equivalent to about of its own weight.
  • the cloth was then dried at a moderate temperature and then impregnated with a solution of 60 parts by volume of commercial 40% formaldehyde and 4 parts by volume of sulphuric acid (specific gravity 1.72) in 40 parts by volume of water. The cloth was then allowed to stand exposed to the air for 6-7 mins. to allow the delustring effect to develop, after which time the cloth was Washed first in water, then in soap solution and finally rinsed in water and dried.
  • Example 7 Delustred coloured design with an undelustred background
  • vat dye ester for example, Soledon or Indigosol dyestufis
  • This mixture is added to 9 parts by volume of a paste made by mixing lbs. urea, 8 lbs. sodium chlorate, 6 lbs. ammonium chloride, 3 ozs.
  • a cotton viscose mixture fabric was printed with this colour, dried at a moderate temperature and passed through an ager fora-5 mins. to develop the colour.
  • the fabric was then impregnated with a cold solution containing 65 parts by volume of commercial 40% formaldehyde, 5 parts by volume of sulphuric acid (specific gravity 1.72) and 30 parts by volume of water and then passed face downwards through a two-bowl mangle.
  • the cloth was then allowed to stand exposed to the air for 6-7-mins. during which time the delustering effect developed.
  • the fabric was then washed in water and again in dilute soda ash solution and finally washed in boiling soap solution.
  • the fabric was then rinsed in water and finished in the usual way.
  • Components of synthetic condensation products other than those indicated may be used but those which will react rapidly in presence of a catalyst such as an acid are particularly suitable.
  • the process differs from that disclosed in German Patent 499,818 in that precipitation of an insoluble condensation product is designedly brought about to make resin formation dimcultz it is not necessary to dry the material and heat it to a high temperature since the intermediate compound can be made insoluble while the fabric is in the wet stateby the action of acid at room temperature.
  • the treatment is effected in such manner as to cause a large reduction of lustre.
  • the lustre of a fabric is due to the specular reflection (i. e., reflection as from a mirror) of light from the fibres.
  • the treatment should not be such as to deposit a coherent resinous layer.
  • the time of treatment must be sufliciently prolonged to allow of adequate precipitation, though this varies with acidity, dilution, temperature and ratio of formdrying the same. to remove therefrom'any substance or ingredient adapted to cause resin formation upon the drying of said material. Illustratively, this may be accomplished by washing the fabric with an aqueous solution pursuant to the various examples hereinabove disclosed.
  • a process for delustring textile material in aqueous solution which comprises impregnating said material with a solution containing urea and contacting the so treated material in another phase with another solution containing an aldehyde and an acid, whereby an insoluble, nonresinous, synthetic condensation product in particulate form is precipitated in situ on the material to delustre the same, and washing said wet textile material having the non-resinous product precipitated thereon to remove any ingredient adapted to cause resin formation upon drying said material.
  • a process for delustring textile material 1 which comprises impregnating said material with an aqueous solution containing urea, drying, printing with an acid-resisting agent, and contacting the so treated material in another phase with another aqueous solution containing an aldehyde and an acid, whereby an insoluble, nonresinous, synthetic condensation product in particulate form is precipitated in situ on the material to delustre the same, and washing the wet textile material with substances adapted to substantially completely remove any um'eacted ingredients prior to drying the same.
