Problems solved by technology

This is problematic with both colored and white fabrics, but may be particularly noticeable on white or light colored fabrics, such as around linings and cuffs where incomplete cleaning occurs
Since it can cause a bad smell, this could also be the problem

Embodiment 1

[0298] Example 1: Deposition test on model surface using DPI .

[0299] To illustrate the increased deposition of nucleases on hydrophobized surfaces, the following experiments were performed: Using a dual polarization interferometer (Farfield Analight Bio200), we recorded the deposition of nucleases (SEQ ID NO 1 ) on two model surfaces.

[0300] First pure quartz hydrophilic surface: use UV / Ozone Procleaner TM (BioforceNanosciences) Expose it to UV light for 30 minutes to process Anachip from Farfield TM Flakes. The surface is then highly hydrophilic.

[0301] The second surface is hydrophobically modified: Anachip treated with UV-O3 TM Immerse in a solution of 1% (chloromethyl)trimethylsilane (Sigma Aldrich) in toluene for 30 seconds and rinse with ethanol. This approach grafts silanes onto the silica surface, increasing the concentration of methyl groups on the surface, making it hydrophobic.

[0302] The treated flakes were then placed in the DPI instrument and expo...

Embodiment 1-7

[0308] Example 1-7 Heavy Duty Liquid Laundry Detergent Composition

[0309]

[0310]

[0311] Based on total cleaning and / or treatment composition weight. Enzyme content is reported as raw material.

Embodiment 8 to 16

[0312] Examples 8 to 16 unit dose composition

[0313] These examples provide various formulations for unit dose laundry detergents. Compositions 8 to 12 comprise a single unit dose compartment. This film is used to encapsulate the composition in PVA.

[0314]

[0315]

[0316] Based on total cleaning and / or treatment composition weight. Enzyme content is reported as raw material.

[0317] In the following examples, the unit dose has three compartments, but similar compositions can be prepared with two, four or five compartments. The membrane used to encapsulate the compartment is polyvinyl alcohol.

[0318]

[0319]

[0320]

[0321] Enzyme levels are reported as raw materials based on total cleaning and / or treatment composition weight.

Abstract

The invention discloses a method for treating a hydrophobically-modified textile with an aqueous solution of a nuclease enzyme, preferably a deoxyribonuclease or ribonuclease enzyme, rinsing and drying the textile. Use of the finishing step for improved cleaning with an aqueous solution of a nuclease enzyme, preferably a deoxyribonuclease or ribonuclease enzyme.

Description

technical field [0001] The present invention relates to a method for treating the surface of textiles. Background technique [0002] Fabric whitening is a constant challenge for laundry detergent manufacturers. The specific problem may be the accumulation of dirt over time. This is problematic with both colored and white fabrics, but can be especially noticeable on white or light colored fabrics, such as around linings and cuffs where incomplete cleaning occurs. Since it can cause a bad smell, that could also be the problem. Laundry detergent manufacturers can consider many options based on the different cleaning technologies available such as surfactants, bleaches and enzymes. Many different types of enzymes are available to detergent formulators for cleaning different types of soils such as lipase, protease, amylase, cellulase, peroxidase, aryl esterase, cutinase, pectinase, mannan carbohydrases and deoxyribonucleases. However, there remains a need for a cleaning or t...
