Anti-pilling fabric softener compositions

The present article relates to the use of fabric softener compositions comprising selected additives for the antipilling treatment of textile materials in domestic applications. In particular it relates to textile softening compositions for use in a textile laundering operation to impart excellent antipilling benefits on the textile.

As it is well known, the pill formed on worn clothing markedly detracts from the appearance and feel of the clothing. The occurrence of pill is particularly a problem in the field of knitted materials, so that it has been greatly desired to seek measures for preventing the occurrence of pill on knitted fibre materials. Methods of improving the feel of worn clothing are known, such as rinse-added softener compositions. Typically, such compositions contain a water- insoluble quaternary-ammonium fabric softening agent. Nevertheless, such cationic softening compositions tend to increase the formation of pill at the fabric surface.

It has been found that the use of selected polyethylene or polysilicic acid, or mixtures thereof, in fabric softener compositions provide excellent antipilling effects when applied to fabrics during a textile laundry operation.

The fabric softener composition will be used after the textile fibre materials have been washed with a laundry detergent, which may be one of a broad range of detergent types.

The fabric softener composition preferably has a solids content of 3 to 25% at a temperature of 120oC and a pH value from 2 to 7.

The emulsifiable polyethylene (polyethylene wax) is known and is described in detail for example, in DE-C-2,359,966, DE-A-2,824,716 and DE-A-1,925,993. The polyethylene wax is employed in the form of dispersions.

The polysilicic acid dispersions are based on colloidal polysilicic acid.

The additives selected from the group consisting of a polyethylene and a polysilicic acid are used in an amount of 0.1 to 5 % by weight.

A highly preferred fabric softener composition comprises:

a) 2 to 25 % by weight, based on the total weight of the softener composition, of a cationic softening agent,
b) 0.1 to 5 % by weight, based on the total weight of the softener composition, of at least one polyethylene,
c) optionally perfume, preservative and/or dyestuff, and
d) water to 100 % by weight.

Another highly preferred fabric softener composition comprises:
a) 2 to 25 % by weight, based on the total weight of the softener composition, of a cationic softening agent,
b) 0.1 to 5 % by weight, based on the total weight of the softener composition, of at least one polysilicic acid,
c) optionally perfume, preservative and dyestuff, and
d) water to 100 % by weight.
