Definitions

  • the invention relates to the use of a fabric softening clay for control and prevention of fibre damage caused by washing and use of fabrics.
  • a typical wash will include some fabric containing cellulose based fibres. Abrasion of cellulose based fibres under wet conditions results in cotton fibre fibrillation whereby the cotton fibres are gradually broken down into their component fibrils and into fibrillar sheets. Such fibrillation is an important mechanism by which fabrics are damaged during wash processes. Alternatively abrasion of cellulose fibres occurs when a garment is dry. This abrasion or dry wear takes the form of the fibre cracking.
  • WO 89/04862 relates to a detergent composition for cleaning and softening fabrics in which cellulase granulates containing calcium carbonate are used in certain combinations with a fabric softening clay to wash cotton swatches.
  • a composition comprising cellulase and clay is said to improve the appearance of the cotton fabric by improved colour and anti-pilling performance. These improvements are probably due to the action of cellulase on cotton which is a cellulosic fibre.
  • GB 1 400 898 relates to the use of certain clays in detergent compositions for imparting a softening benefit to fabrics washed therewith. (No pilling prevention or control is mentioned.)
  • inhibitor includes a component which confers protective care or protection on a fibre.
  • it encompasses those materials which reduce the damage to the fibre which would otherwise occur during the course of wearing and washing a garment.
  • Suitable clays for use in the present invention include various heat treated kaolins and various multi-layer smectites eg. bentonites.
  • Preferred clays are softening clays such as smectite softener clays as described in GB 1 400 898, EP 350 288 and EP 0 297 673.
  • Montmorillonite clays are especially preferred eg. Volclay.
  • Softening clays are used in the preferred compositions at levels of at least 0.1%, generally 1-30%, preferably 2-10% by weight.
  • the invention further provides the use of a fabric softening clay in a fabric conditioning composition for the prevention of fibre damage and to protect fibres.
  • This aspect of the invention has the advantage that the use of the fabric softening clay can be carried out as part of a rinsing process giving a desirable overall effect of softening and fibre damage control or prevention. Further more the clay when deposited in this manner can protect the fibres after the rinsing process and during wear and use of articles and the protection conferred can be carried over to the next wash.
  • the fabric softening clays may be used in admixture with one or more fabric softening materials such as cationic fabric softeners or amine materials.
  • suitable cationic fabrics softeners include substantially water insoluble quaternary ammonium compounds such as for instance dihardened tallow dimethyl ammonium chloride, imidazolonium salts and similar di (long-chain) quaternaries and ester-linked quaternaries as for instance disclosed in EP 239 910, US 3 915 867 and US 4 137 180.
  • Examples of amine materials include tertiary amines and those disclosed in EP 0 199 383 and EP 0 345 842.
  • the fabric softening composition can also contain fatty acids for example C8-C24 alkyl or alkenyl monocarboxylic acids or polymers thereof.
  • fatty acids for example C8-C24 alkyl or alkenyl monocarboxylic acids or polymers thereof.
  • saturated fatty acids are used, in particular, hardened tallow C16-C18 fatty acids.
  • the fatty acid is non-saponified, more preferably the fatty acid is free; for example oleic acid, lauric acid or tallow fatty acid.
  • the level of cationic for use in the fabric softening composition according to the invention may constitute from 5 to 97 wt% of the total wt% of the composition.
  • compositions of the invention preferably have a pH of more than 2, more preferably between 2 and 5.
  • compositions can also contain one or more optional ingredients, selected from non-aqueous solvents, pH buffering agents, perfumes, perfume carriers, fluorescers, colorants, hydrotropes, anti-foaming agents, anti-redeposition agents, enzymes, freeze-thaw stabilisers, optical brightening agents, opacifiers, anti-shrinking agents, anti-wrinkle agents, anti-spotting agents, germicides, fungicides, anti-oxidants, anti-corrosion agents, drape imparting agents, antistatic agents and ironing aids.
  • optional ingredients selected from non-aqueous solvents, pH buffering agents, perfumes, perfume carriers, fluorescers, colorants, hydrotropes, anti-foaming agents, anti-redeposition agents, enzymes, freeze-thaw stabilisers, optical brightening agents, opacifiers, anti-shrinking agents, anti-wrinkle agents, anti-spotting agents, germicides, fungicides, anti-oxidants, anti-corrosion agents
  • composition may also contain nonionic fabric softening agents such as lanolin and derivatives thereof.
  • the invention further provides the use of a fabric softening clay in a composition comprising a detergent active for the prevention of fibre damage or to protect fibres.
  • a fabric softening clay in a composition comprising a detergent active for the prevention of fibre damage or to protect fibres.
  • the use of softening clays may further confer a softening benefit, in such detergent compositions.
  • the detergent active material may be selected from soaps, non-soap anionic, nonionic, zwitterionic and amphoteric synthetic detergent active materials and optionally one or more fabric softening materials.
  • Anionic surfactants useful in the present invention include: Linear alkyl sulphonates.
  • suitable synthetic anionic detergent compounds are sodium and potassium alkyl sulphates, especially those obtained by sulphating higher (C8-C18) alcohols produced for example from tallow or coconut oil, sodium and potassium alkyl (C9-C20) benzene sulphonates, particularly sodium linear secondary alkyl (C10-C15) benzene sulphonates; sodium alkyl glyceryl ether sulphates, especially those ethers of the higher alcohols derived from tallow or coconut oil and synthetic alcohols derived from petroleum; sodium coconut oil fatty monoglyceride sulphates and sulphonates; sodium and potassium salts of sulphuric acid esters of higher (C8-C18) fatty alcohol-alkylene oxides, particularly ethylene oxide, reaction products; the reaction products of fatty acids such as coconut fatty acids esterified with isethionic acid and neutralised with sodium hydro
  • Suitable nonionic compounds which may be used include in particular the reaction products of compounds having a hydrophobic group and a reactive hydrogen atom, for example aliphatic alcohols, acids, amides or alkyl phenols with alkylene oxides, especially ethylene oxide either alone or with propylene oxide.
  • Specific nonionic detergent compounds are alkyl (C6-C22) phenols-ethylene oxide condensates, generally up to 25 EO, i.e. up to 25 units of ethylene oxide per molecule, the condensation products of aliphatic (C8-C18) primary or secondary linear or branched alcohols with ethylene oxide, generally up to 40 EO, and products made by condensation of ethylene oxide with the reaction products of propylene oxide and ethylenediamide.
  • Other so-called nonionic detergent compounds include alkyl polyglycosides, long tertiary amide oxides, glucamines, long chain tertiary phosphine oxides and dialkyl sulphoxides.
  • Amounts of amphoteric or zwitterionic detergent compounds can also be used in the compositions of the invention but this is not normally desired due to their relatively high cost. If any amphoteric or zwitterionic detergent compounds are used it is generally in small amounts.
  • the effective amount of the detergent active or fabric softening compound or compounds used in the composition of the present invention is generally in the range of up to 50%, preferably up to 40% by weight, most preferably not more than 30% by weight of the composition. Preferably the level is above 1%, most preferably more than 2%.
  • compositions of the invention may include detergency builder to improve the efficiency of the detergent active, in particular to remove calcium hardness ions from the water.
  • the builder material may be selected from inorganic precipitating builders materials (such as alkali metal carbonates, bicarbonates, borates, orthophosphates and silicates), sequestering builder materials (such as alkali metal pyrophosphates, polyphosphates, amino polyacetates, phytates, polyphosphonates, aminopolymethylene phosphonates and polycarboxylates), ion-exchange builder materials (such as zeolites and amorphous alumino-silicates), organic precipitating builder materials (such as those having the formula (I): wherein: R1 is C10-C24 alkyl or alkenyl, or an arylalkyl or alkylaryl group of equivalent chain length; X is CH, CR2, N or CON; R2 is C1-C3 alkyl; Z is COO
  • builder materials include sodium tripolyphosphate, mixtures thereof with sodium orthophosphate, sodium carbonate, mixtures thereof with calcite as a seed crystal, citrates, zeolite and the sodium salt of nitrili- triacetic acid.
  • Zeolites that find application in the present invention there may be mentioned: Zeolite A and X and mixtures thereof, particularly Zeolite 4A. Also of interest is Zeolite P described and claimed in EP0384070.
  • the level of such builder material in the compositions of the invention may from 2 to 80% by weight, preferably from 7% to 70% by weight and most preferably from 14% to 60% by weight.
  • compositions comprising a detergent active according to the invention preferably are neutral or slightly alkaline when added to water at a concentration of 1% by weight at 25°C. Neutral compositions are especially preferred for wool wash use.
  • a composition of the invention can contain any of the conventional additives in the amount in which such additives are normally employed in fabric washing detergent compositions.
  • Optional additives include the lather boosters such as alkanolamides, particularly the monoethanolamides derivatives from palm kernel fatty acids and coconut fatty acids, lather depressants, oxygen-releasing bleaching agents such as sodium perborate and sodium percarbonate, peracid bleach precursors, chlorine-releasing bleaching agents such as trichloroisocyanuric acid, inorganic salts such as sodium sulphate, and, usually present in very minor amounts, fluorescent agents, perfumes including deodorant perfumes, enzymes such as cellulases, lipases, proteases and amylases, germicides and colourants.

  • Figure 1 is a diagrammatic representation of the fibre damage test apparatus used.
  • Figure 2 is a photograph of fibre damage caused by dry abrasion.
  • Figure 3 is a photograph of fibrillation caused by wet abrasion.
  • Figure 4 is a photograph of fibres washed without clay.
  • Figure 5 is a photograph of fibres washed with clay.
  • Figure 6 is a photograph of fibres rinsed with clay.
  • Figure 1 shows a yarn on yarn abrasion tester with a test yarn 1 comprising fibres.
  • the two ends of the yarn are attached to metal links 2 and 3.
  • Metal link 2 joins the yarn to a cord 4 which passes over a first upper yarn guide pulley 4A and is attached to a tensioning weight 5. Typically a 20g tensioning weight is used.
  • the other end of the yarn is attached to a second cord 6 by the metal link 3.
  • the yarn is twisted about itself in the test region 7 and is weighed down by passing the yarn around a lower yarn guide pulley 8.
  • the second cord 6 passes over a second upper yarn guide pulley 9 and is attached to an electrically driven reciprocating means 10.
  • a beaker 11 is provided for containing water or aqueous media used to test the yarn in wet conditions.
  • the test method consists of attaching the yarn to be tested to one of the metal links, passing the yarn around the lower yarn guide pulley 9 and then twisting the yarn around itself a predetermined number of times to form the region 7, before attaching it to the other metal link. If required, the beaker is filled with an aqueous test medium. The reciprocating means is then switched on. A record is kept of the number of oscillations of the reciprocating means before failure. In each of the following examples the test was repeated a number of times and very high or low results discarded before a statistical analysis was made of the remaining date. (Very high or low results are due to defective fibres).
  • Comparative examples are illustrated by a letter. Examples of the invention are illustrated by a number.
  • the yarns were then rinsed for 5 minutes at room temperature. Four rinses were applied.
  • Example 3 shows that further fibre damage is reduced if clay is present in both the wash and the final rinse.
  • Example 4 was treated with Na Montmerillonite clay and washed in New Persil Automatic Biological.
  • Example 5 was treated with Na Montmerillonite clay in an aqueous solution (tg washing powder per L). (This treatment simulates adding clay during the rinse).
  • Example D was not treated and washed with New Persil Automatic Biological
  • Example D A photograph of Example D is shown in Figure 4
  • Figure 5 is a photograph of Example 4
  • Figure 6 is a photograph of Example 5.
  • the photograph show that clay mitigates fibre damage when added in a rinse cycle or during the main wash. Furthermore it can be seen that clay can reduce fibre damage/fibrillation and thus increase yarn life time more effectively when it is applied to the last rinse.
