Linen treatment compositions and linen processes are disclosed which help to prevent iron deposition from wash water, and/or redeposition after iron containing stain (such as blood) removal by alkaline detergents. The linen treatment composition is a combination of a hydroxycarboxylic acid and an acid source, which may be organic or inorganic. The invention provides for effective iron control in a phosphorus-free formula that is also free of toxic or hazardous chemicals and includes sustainable, environmentally friendly ingredients, while still providing effective iron control.

The present invention relates to a process and a device for chlorine-free shrinkproof treatment of a wool raw material and an article thereof. In particular, the process of the present invention comprises the steps of a chlorine-free shrinkproof treatment, washing with water, protease inactivation, a softening treatment, dehydration, drying and the like, wherein a chlorine-free catalysis system consisting of a protease, a specific organic phosphine compound and the like is selected, removing the scale layer on the surface of wool fibres cooperatively and efficiently and modifying the scale layer so as to improve the shrinkproof performance of wool articles. The process of the present invention can completely replace the chloridisation shrinkproof method in the prior art, and is not only environmentally friendly, but also has low requirements for equipment, can be operated continuously and is suitable for large-scale industrial production.

A method of treating a fabric, the method comprising the step of: subjecting the fabric to a wash liquor comprising from 100 ppm to 600 ppm of a surfactant system; and rising the fabric with a rinse liquor comprising from about 110.sup.2 to about 110.sup.8 CFU/l of the aqueous liquor, of bacterial spores.

The present invention relates to a method of laundering fabric. The method subjects the fabric to be laundered to an acidic washing step. Following the acidic washing step, the fabric is removed from the acidic wash bath and subjected to a total abrasive force of from 1.5 kg to 10 kg. The fabric is then rinsed with water.
