Definitions

  • This invention relates to the use of a solvent consisting of propylene glycol monomethyl ether and water for dry cleaning.
  • 1,1,1-Trichloroethane and perchloroethylene which have been used in the prior art as solvents for dry cleaning, have the problem of polluting underground water, while some kinds of chlorofluorcarbons have the problem of destroying the ozone layer, and therefore there is currently a great need for rapid investigation of alternative substances.
  • US-A-3,701,627 discloses a process for chemical cleaning of textiles with a solvent mixture consisting essentially of a halogenated hydrocarbon, an alcohol (optionally ethyleneglycol monomethylether) and water.
  • JP-A-62 201977 reports a liquid for erasing a printing on a cloth, e.g., a hotel name, a hospital name etc. printed on various linens used in hospitals, hotels etc.
  • the liquid is propyleneglycol monomethylether in combination with a reductive or oxidative bleaching agent such as hypochlorite, oxalic acid or citric acid.
  • the present inventor has previously investigated the dry cleaning capabilities of 81 kinds of solvents (Journal of the Japan Research Association for textile End-use 27, 8 (1986), 352 - 359), but there was no solvent which met all requirements.
  • a solvent for dry cleaning must meet several requirements such as detergency, handleability, safety, etc. More specifically, detergency is measured according to "solubility" and "dispersibility" of various types of soil, including oil-soluble soils such as skin fat, fat and oil, oil mist, etc.; water-soluble soils such as sweat, water-soluble foods; dirts such as sludge, dust, etc., the degree of "counter-contamination", that is, soil washed from clothing migrating back from the cleaning liquid to the clothing, and the degree of small surface tension of the solvent penetrating into the clothing and between the soils.
  • oil-soluble soils such as skin fat, fat and oil, oil mist, etc.
  • water-soluble soils such as sweat, water-soluble foods
  • dirts such as sludge, dust, etc.
  • counter-contamination that is, soil washed from clothing migrating back from the cleaning liquid to the clothing, and the degree of small surface tension of the solvent penetrating into the clothing and between the
  • "handleability” is measured by easy drying of the article to be washed, long life, easy distillation and recovery of the solvent, suitability for machines with no corrosion of metals, easy workability and management with low odor, no remaining odor on the article to be washed, etc.
  • "Safety” is measured by the degree of collapse of form of the article to be washed, denaturation of the article to be washed such as by yellow discoloration, run-off of dye, dissolution of auxiliary items such as buttons, high ignition point and flash point, low toxicity, etc.
  • PM Propylene glycol monomethyl ether
  • the present invention relates to dry cleaning by using a solvent consisting of PM and water.
  • the water content is not more than 50 %, preferably 0.4 % to 25 % with respect to the total volume of the solvent for dry cleaning. It is preferable that the water content is not more than 25 %, since the shrinkage of a weft of a cotton remains by 5 %. It will be seen from the various test results described below that PM has vast possibilities.
  • PM has both oil solubility and water solubility, and therefore is as effective on oil-soluble soils as the solvent of the prior art, and exhibits relatively better solubility for water-soluble soils, although inferior to water.
  • the chlorine type solvents of the prior art use soap to aid in dissolving performance for water-soluble soils
  • PM exhibited good detergency for water-soluble soils on its own.
  • PM has a surface tension of 27.7, which is greater than that of petroleum (18 - 19) and CFC-113 (17.3), and comparable to perchloroethylene (32.3) and 1,1,1-trichloroethane (25.6).
  • a solvent with little counter-contamination is good in the finishing of dry cleaning, and can clean even with a liquid containing a great deal of contamination, and the number of distillations may be economically reduced.
  • Counter-contamination is determined in consideration of the type of contamination (solute), the solvent and the kind of clothing, and therefore, the following test was carried out: as the water-soluble solute soy sauce (0.5 ml) and coffee (0.5 g) were used; as the dispersible solute carbon black (0.04 g) was used; as the oil-soluble solute waste oil after prolonged usage of gear oil (2 g) was used and, as the miscible solute, distillation residue of cleaning (0.04g) was employed.
  • the test was conducted by immersing and stirring a cloth strip of 2.5 x 2.5 cm in 75 ml of a solvent containing each solute dissolved therein, and soaking it for 5 minutes. After air drying the reflectance of each cloth strip was measured by UV-200, and counter-contamination ratio was determined using the following formula. The results are shown in Table 2.
  • Soy sauce is precipitated with a chlorine type solvent to float as a sol.
  • the sol is hydrophilic, and therefore firmly adheres onto cotton, having a hydrophilic surface. It did not adhere to the wool or polyester, which have hydrophobic surfaces.
  • soy sauce was completely dissolved in water and PM, no dying or counter-contamination was exhibited.
  • Coffee In a chlorine type solvent and PM, the solute floats as solid fine particles. The particles adhered selectively with perchloroethylene and CFC-113. They did not adhere with trichloroethane and PM. On the other hand, dyeability was great with water.
  • Carbon black This was not dissolved, but rather dispersed in all of the solvents, and there was no significant difference depending on the solvent.
  • Waste oil This was completely dissolved in a chlorine type solvent, without counter-contamination. On the other hand, in water and PM the oil floated like a sol in the solution and since the sol is lipophilic it adhered onto the wool and polyester which have lipophilic surfaces.
  • Distillation residue This is a mixture of water-soluble, dispersible and oil-soluble residues and further contains a soap for charge and therefore may be considered to approximate the conditions of practical dry cleaning.
  • a chlorine type solvent counter-contamination on wool and cotton was marked, while the results with water were good. With PM, the results were between those of water and chlorine type solvents.
  • PM exhibits low counter-contamination for all kinds of contamination and clothing, and therefore can be evaluated as an excellent solvent for dry cleaning.
  • a specific feature of dry cleaning is that water absorptive fibres are prevented from form collapsing or shrinkage of washed products by swelling resulting from water washing. Shrinkage of the clothing when washed with PM or mixtures consisting of PM and water was tested.
  • the flash point of PM is 36 to 38 °C and readiness of combustion is approximately equal to that of petroleum solvents.
  • the flash point of a mixture with 50% water is 62 to 64 °C, showing that elevation of the flash point can be effected by mixing with water.
  • test strip 1 x 2 cm each of iron, aluminium, and stainless steel was dipped in the solvent at room temperature for one week and then taken out and left to stand in air for 3 months for judgement of the degree of oxidation. In PM no change was observed at all for any of the test strips.
