Description

Contain laundry detergent composition to the outward appearance of the fabric that washed and whole favourable cellulosic polymer

Technical field

The present invention relates to liquid or granular heavy duty type laundry detergent composition, it contains the ether of cellulose material of the modification of some kinds, helps the fabric that washs in the washing soln of being made by said composition and the outward appearance and the whole structure of textiles.

Background of the present invention

As everyone knows, use and laundering of textile fabrics and textiles, for example the alternate cycles of Mo Sun clothing item inevitably to the fabric that uses and wash and textiles outward appearance and produce adverse influence on the whole.Fabric and textiles only will be damaged with use through after a while.Laundering of textile fabrics and textiles must be removed in daily use and assemble thereon and dirt wherein and stain.But washing operation itself can accelerate and promote the destruction to the integral body and the outward appearance of these fabrics and textiles through repeatedly circulating.

Fabric destruction whole and outward appearance itself can illustrate in several ways.The mechanical effect of washing can make staple fibre fall down from the fabric/textile structure with braiding of weaving.These fibers that fall down form fiber flock, fine hair or " balling-ups ", can fabric see them outwardly, and influence the new and old of appearance of fabrics.In addition, repeated washing fabric and textiles, particularly employing contain the laundry product of SYNTHETIC OPTICAL WHITNER, can remove the dyestuff on fabric and the textiles, reduced the density of color, the result cause fade, worn appearance, and be to cause in many cases by the color harmony light and shade that changes color.

As previously mentioned, obviously need find a kind of material, it be introduced in the detergent for washing clothes product, and they are had an effect with the fiber that adopts this class Betengent product laundering of textile fabrics and textiles, thereby reduces or reduce to be washed the ruined trend of outward appearance of fabric/textile.All these class Betengent product additive materials should be able to help the outward appearance and the globality of fabric certainly, and do not influence the ability that detergent for washing clothes is brought into play its clean fabric function.The objective of the invention is to contain the detergent composition of the fiber substance of some type, it is had an effect in a desired manner.

Summary of the present invention

Laundry detergent composition of the present invention contains the ether of cellulose fabric conditioner of modification of some kinds of the organic or inorganic detergent builder of the detergent surfactant of 1% to 80% weight of having an appointment, about 0.1% to 80% weight and about 0.1% to 8% weight.Detergent surfactant and detergent builder material can be any materials that can be used in the common detergent for washing clothes product.The molecular weight of the ether of cellulose material of modification is about 10000 to 2000000, and has the anhydroglucose unit that multiple replaces, and this unit has general structure I, II and the III in below " detailed description of the present invention " part.(in the listed hereinafter general structure, substituting group is on the specific position of glucose anhydro ring of the cellulose ether polymer that repeats to form replacement.Can think that this only is in order to illustrate, and this class substituting group can find on any carbon atom of glucose anhydro ring.)

Liquid detergent composition can be by mixing main and optional components with required order, makes the composition that contains component with desired concn and prepare.Liquid composition of the present invention also can be " concentrated type ", and in this case, liquid detergent composition of the present invention contains a spot of water of comparing with the conventional liq washing composition.

Adding the ether of cellulose component in the liquid detergent composition of the present invention can finish by mix required ether of cellulose simply in the liquid washing agent aqueous solution.Ether of cellulose can change viscosity or other rheological property of detergent product.Therefore must compensate variation by changing the hydrotropic agent that adopted and/or solvent types and amount by the rheology that adds the caused detergent product of ether of cellulose.

F) Fabric cleaning process

The present invention also provides a kind of method of laundering of textile fabrics, and by this method, cellulose polymer compound of the present invention produces useful effect to the outward appearance of fabric.This method is that this kind fabric is contacted with the aqueous cleaning solution of being made by the previously described detergent composition of significant quantity or made by the single component of said composition.It generally is to carry out under stirring condition that fabric contacts with washing soln, although also can adopt composition of the present invention to make to be used for the immersion aqueous solution that need not stir of clean fabric and processing.

Preferably in washing machine, stir to clean well.Preferably dry in the normal laundry drying machine after the washing.The liquid of the significant quantity in the aqueous cleaning solution in washing machine or granular detergent composition preferably about 500 to about 7000ppm more preferably from about 1000 arrive about 3000ppm.

G) Textile finishing

The ether of cellulose of previously described modification as laundry detergent composition of the present invention also can be used for handling and regulating fabric and textiles under the situation of tensio-active agent that lacks detergent composition embodiment of the present invention and adjuvant component.Therefore, the fabric regulating composition that for example only contains modified cellulose ethers itself or contain the aqueous solution of modified cellulose ethers can add in the rinse cycle process of conventional home laundry operation, is beneficial to required appearance of fabrics and overall performance that the front is put down in writing.
