Abstract
The present invention relates to a method of cleaning fabrics in washing machines which have parts made of natural rubber using laundry detergents comprising amido-derived bleaching activators and a source of hydrogen peroxide, such that said natural rubber parts of said machines are substantially undamaged by products of the perhydrolysis reaction between the activator and hydrogen peroxide.
Description
Field of the present invention
The present invention relates to contain the detergent for washing clothes of activated bleaching system.
Background of the present invention
People know already peroxygen bleach for get on from fabric except that spot and/or dirt be effectively, but this SYNTHETIC OPTICAL WHITNER is a temperature dependent.In 60 ℃ the laundry aqueous solution, peroxygen bleach only part is effective.In temperature was lower than 60 ℃ the aqueous solution, peroxygen bleach became relative nullity.Therefore, people carried out a large amount of industry research with exploitation contain activator bleach systems so that peroxygen bleach in being lower than 60 ℃ the laundry aqueous solution effectively.
Open in the prior art as many materials of effective bleach-activating agent.Can widely used a kind of activator be tetraacetyl ethylene diamine (TAED).TAED especially provides effective hydrophilic cleaning to the beverage spot, but for dark yellow spot, as those spots that the grease by human secretory produces, the effect of TAED is limited.Another kind of type activator such as nonanoly acyloxy benzene sulfonate (NOBS) and to contain chain alkyl other activator partly usually be hydrophobic in essence and provide fabulous cleaning performance for dark spot.Yet many hydrophobic activation agent of being developed so far can cause damage for natural rubber parts used in some washing machine.Because to this negative interaction of part of washing machine, therefore the selection for the washing composition that adds bleach systems is restricted.Especially all the more so for the used washing composition/SYNTHETIC OPTICAL WHITNER in Europe, because many washing machines that make in Europe have been equipped with key part, as drainage tray flexible pipe and electronic packing ring, they are that natural rubber makes.Therefore need a kind of bleach system, it can be removed dark dirt and not damage the natural rubber parts that exist in the washing machine fully.
Now determined generally to contain hydrophobic bleach activator and hydroperoxide source in the conventional bleaching system, activator passed through hydrolysis reaction and formed peroxyacid bleach.The by product of crossing hydrolysis reaction between this bleach-activating agent and the hydrogen peroxide is diacyl peroxide (DAP) material.People also further find, the oily mater insoluble often by the DAP material that hydrophobic bleach activator produces, that difference is dispersed, and it has constituted the residue that can be deposited on the natural rubber machine part that contacts with the aqueous solution of doing washing.This oily DAP residue can form film on the natural rubber machine part, and rubber is produced free radical and superoxide damage, finally causes component failure.Especially for the rubber components that contacts with wash water solution for a long time, all the more so as the drainage tray flexible pipe.
According to the present invention, have now found that a class has formed hydrophobic amido peracid derived from the hydrophobic bleach activator of amic acid through hydrolysis reaction, and do not produce deleterious oily DAP class material.The present invention without limits here, it is believed that by derived from the bleach-activating agent of amic acid to cross the DAP class material that hydrolysis reaction produces be insoluble crystalline solid.This solid DAP material does not form mulch film; Therefore the natural rubber part of washing machine does not contact with DAP class material for a long time, and keeps not damaged by bleach system of the present invention substantially.
Therefore the invention solves for effective hydrophobic bleach agent system need problem for a long time, this hydrophobic bleach system does not produce free radical for the natural rubber parts in the washing machine and superoxide damages.The invention provides in washing machine method, and natural rubber is not damaged by bleach system substantially with the bleach system laundering of textile fabrics with parts that natural rubber makes.

Detailed description of the present invention
The present invention relates to the method for laundering of textile fabrics in the automatic washing machine of the parts that the rubber that has the oxidative degradation sensitivity makes.The bleach system that uses among the present invention comprises that to the natural rubber article that natural rubber part of washing machine and other contact with bleach system the fabric that contains natural rubber and natural rubber elastic material is safe.The bleach system that uses among the present invention can be effectively and the fabric face bleaching is provided fully, gets on except that spot and/or dirt from fabric thus, comprises " dead color " dirt.Dark-coloured dirt be repeatedly use with cycles of washing after still amass dirt on fabric, therefore, it causes that white fabrics becomes ash or yellow hue at last.These dirts may be the mixtures of particle and greasy material.Remove this type dirt and be sometimes referred to as " cleaning dark-coloured fabric ".
Other advantages that bleach system of the present invention and activator provide are, they are safe to fabric unexpectedly and cause fading still less than other activator when using by method provided by the invention.
Its bleaching mechanism, especially superficial bleaching mechanism is not fully by known to the people.Yet, it is generally acknowledged that bleach-activating agent has formed peroxycarboxylic acid through carrying out nucleophilic attack by superoxide anion (it is to be produced by the hydrogen peroxide that peroxygen bleach is emitted).This reaction was commonly referred to hydrolysis reaction.
It is also believed that the bleach-activating agent among the present invention can even more effectively emit peroxygen bleach under laundry aqueous temperature (wherein bleach-activating agent does not need the temperature of activated bleaching agent, promptly more than 60 ℃).Therefore, use bleach system of the present invention, only need a small amount of peroxygen bleach just to obtain obtaining the superficial bleaching performance of par with independent use peroxygen bleach.
