Definitions
- the invention relates to the use of a clay and especially 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-A-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-A-1400898 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).
- EP-A-585040 and EP-A-585039 disclose the use of fabric softening compositions containing quaternary ammonium compounds for the use as fabric damage inhibitors or reducers.
- EP-A-614966 published on 14 September 1994 discloses the use of a fabric softening clay as an additive to reduce or prevent wash damage, more specifically loss in weight and consequent weakening, of woollen articles in a fabric washing composition containing a proteolytic enzyme as well as surfactant.
- EP-A-612841 published 31 August 1994 discloses the use of a fabric softening clay on keratin-containing fibres such as wool for controlling and for preventing pilling.
- JP-A-91/0241391 discloses the treatment of synthetic fibre textiles to give a pilling resistant finish.
- the treatment is accomplished with inorganic fine particles, one possibility for which is kaolinite, followed by irradiation with ultraviolet light in an ozone atmosphere.
- JP-A-84/0048647 discloses the spinning of polyester yarn which incorporates a small percentage of kaolinite, a number of advantages are mentioned including resistance to pilling.
- 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.
- Damage of fibres can take place in several ways.
- the use of a fabric softening clay particularly addresses the problem of dry damage and fibrillation. Dry damage causes cracking of the fibres. Fibrillation is the splitting of the fibres to form fibrils.
- 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-A-1 400 898, EP-A-350 288 and EP-A-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, imidazolinium salts and similar di (long-chain) quaternaries and ester-linked quaternaries as for instance disclosed in EP-A-239 910, US-A-3 915 867 and US-A-4 137 180.
- amine materials include tertiary amines and those disclosed in EP-A-0 199 383 and EP-A-0 345 842.
- the fabric softening composition can also contain fatty acids for example C 8 -C 24 alkyl or alkenyl monocarboxylic acids or polymers thereof.
- fatty acids for example C 8 -C 24 alkyl or alkenyl monocarboxylic acids or polymers thereof.
- saturated fatty acids are used, in particular, hardened tallow C 16 -C 18 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.
- Fabric softening compositions used according to the invention include compositions containing 5 to 15% by weight of clay.

- Figure 1 is a diagrammatic representation of the fibre damage test apparatus used.
- 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 Montmorillonite clay and washed in New Persil Automatic Biological.
- Example 5 was treated with Na Montmorillonite 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 Example 4 and Example 5 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.
