Problems solved by technology

However, similar to modern wet cleaning, this still requires the clothes to be hung to dry, which often still causes fiber bonding and rough clothes surfaces
Use of softeners can cause residue and leave a "greasy" texture

Embodiment

[0077] Routine test

[0078] 1. Select 15 kg of different woolen garments from multiple manufacturers and place them in a 55 lb. commercial wet washing machine (Trademark: IMESA).

[0079] 2. In the first step, the laundry is washed with a solution of the washing composition at 25° C. for 7 minutes. The aqueous solution was drained and dehydrated at 500 rpm for 1 minute.

[0080] 3. In a second step, the laundry was rinsed with a solution of the preconditioning composition for 4 minutes at 25°C. The aqueous solution was drained and dehydrated at 500 rpm for 1 minute.

[0081] 4. In the third step, the laundry is rinsed with a solution of the conditioning composition for 7 minutes at 25°C. The aqueous solution was drained and dehydrated at 1000 rpm for 4 minutes.

[0082] 5. In the fourth step, the laundry was dried to 3% humidity in a 75 lb. commercial clothes dryer (trademark: IMESA).

[0083] Subsequent evaluation showed that the garment had no dimensional change, no ...

comparative test 1

[0085] Comparable (wet cleaning) products have no oil stain removal power and washing and subsequent drying of the garments is not recommended. Recommended drying is to tumble for 3 minutes and hang to dry overnight.

[0086] Comparative test 1 was limited to the cleaning process described.

[0087] Three different commercially available wet cleaning products were selected and the same type of laundry was cleaned based on the cleaning product manufacturer's recommendations.

[0088] The cleaned laundry was evaluated for cleaning effectiveness and effect on the fibers. All three cleaning products and methods produced visible surface and color changes.

comparative test 2

[0090] In Comparative Test 2, the laundry of Comparative Test 1 was subsequently dried.

[0091] The cleaned and dried laundry was evaluated for cleaning and drying effectiveness and effect on the fibers.

[0092] All three cleaning products and methods produced visible dimensional changes, shrinkage and felting, and color changes.

[0093] Household Washing Machine Test 1

[0094] 1. Select four different wool trousers from multiple manufacturers and place them in the hand wash / wool cycle of a Miele W 1926 (home washing machine).

[0095] 2. In the first step, the laundry is washed at 25°C with a solution of the washing composition. The aqueous solution is drained and dehydrated.

[0096] 3. In the second step, rinse the laundry with clean water only. The aqueous solution is drained and dehydrated.

[0097] 4. In the third step, the laundry is rinsed at 25°C with a solution of the conditioning composition. The aqueous solution is drained and dehydrated.

[0098] 5. I...

Abstract

The present invention relates to compositions and methods for wet-cleaning, in professional or household washing machine equipment, and subsequent drying in a tumbler dryer, of garments made of protein-fibers (animal based fibers) such as wool, cashmere, silk and other sensitive fibers. Using water and certain additives instead of organic solvents, these compositions enable the cleaning, including oil stains removal, and subsequent drying without incurring dimensional changes, shrinkage, surface damages, dye or color loss of dry clean only labeled garments or other delicate garments labeled for special care.

Description

Background technique [0001] The present invention relates to compositions and methods for the wet cleaning (including removal of oil stains) of sensitive garments and other fabrics made from water-sensitive protein fibers such as wool, cashmere or silk, and subsequent washing in the drum. Drying in the dryer without any dimensional changes, surface breakage and loss of dye or color. The compositions and methods of use thereof find application in professional or household cleaning processes. [0002] Sensitive clothing and other fabrics can be washed and dried in a variety of ways using professional wet or dry cleaning methods or modern household laundry equipment. Sensitive items including clothing and fabrics made of wool, silk, rayon, animal hair, animal skins and blends have a tendency to shrink when washed in water. To avoid shrinkage from washing, many of these sensitive garments and fabrics are often dry cleaned. [0003] dry cleaning [0004] By definition, the ter...
