Abstract

A kind of new prescription that is applicable to the powdery dry cleaning composition of pure wool, regenerated fiber, synthon and blended fibre knitwears carpet and pile fabric, to pollution stain common on the above-mentioned fabrics, has effective and tangible cleaning performance as dish oil saucing, laughable fruit juice stain and particulate dust etc.

Description

The prescription of dry-cleaning powder fo carpets

The present invention relates to a kind of new prescription that utilizes macromolecular organic compound as the carpet dry cleaning agent of carrier.

Existing dry cleaning composition is of a great variety because of carpet and fine hair product, as the fabrics made from pure wool, regenerated fiber, synthon and blending etc. such as tufting, jacquard weave and circle suede, and the dirt kind on these fabrics also constantly enlarges, as cola, fruit juice and oily sauce etc., dry cleaning composition has not originally adapted to above-mentioned variation.

The object of the invention is to provide a kind of carpet and fine hair product that can be applicable to that various materials are made, enlarge its kind that takes out stains, improve the new prescription of cleansing power, various spots such as dish oil saucing, cola, fruit juice and miniature grain dust etc. are had tangible cleanup action, and color and luster, fastness and the shrinking percentage to fabric has no effect after cleaning.

The present invention is achieved in that with the suitable high absorbability carrier of a kind of water ratio and serves as the washing composition medium, and bears the dual function of introducing washing composition and having spot.Thereby make washing and float to wash and be able to disposable finishing.The washings of carrier that the present invention introduces is made of jointly two or more tensio-active agent and other washing auxiliary detergents such as non-ionic type and anionic.

The carrier of one of prescription of its integral part is to adopt the methyne urea with good adsorptive power and wear resistance

Principal goods matter, and when making reaction, entrain into an amount of paper pulp fiber and make basic aggregate.Because of 0.01～0.1mm plant paper pulp fiber has the antistatic preferably performance of gathering, can make carrier be applicable to the carpet and the fuzz fabric of various wools, chemical fibre and blending, staple length is controlled at below standard sieve 250 orders simultaneously, makes dry cleaning composition can infiltrate the various fine hair products of knitting type.

What adopt as the actives of two washing composition of prescription is to make after nonionic surface active agent (6501 or 6502) and anion surfactant (as: Sodium dodecylbenzene sulfonate) confuse effect.The ratio of above-mentioned two kinds of materials is 1.5: 1, i.e. tween 0.15～0.4% in whole powdery dry cleaning composition, anion surfactant 0.1～0.3%.By being used of two kinds of promoting agents, enlarged the scope of washing dirt, strengthened soil removability.

Other washing auxiliary detergents of three as prescription are made of following material:

1. with 0.3% sequestrant, tripoly phosphate sodium STPP, it with dirt is separated after dirt mixes with fabric, and the softening tool of hard water is had certain effect.

2. with 0.17% pH value stabilization agent such as yellow soda ash etc., make washing composition have certain pH value, act on when the alkalescence to guarantee to make actives.

3. with 0.2% pH value buffer reagent, as water glass, it can guarantee that washing composition pH value when change in concentration is relatively stable, is promptly beginning to wash when finishing that the carrier water ratio changes in the whole process of washing, and the pH value still keeps one to fix in the scope.

4. with 0.15% solubilizing agent, sodium sulfate or contain the sodium sulfate of ten crystal water to reduce surface tension and constraint threshold concentration, improves rate of adsorption and adsorptive capacity.

5. use 0.05% whitening agent,, increase the reflexed ability of light, make fabric keep certain vivid degree as the fluorescent brightening powder.

6. spices.Available various spices, Shu Yi is as the criterion with sense of smell.

Below be the ratio prescription of the various materials of the present invention:

1. methyne urea-55%

2. nonionogenic tenside (6520)-0.3%

3. anionic surfactant sodium dodecylbenzene sulfonate-0.17%

4. tripoly phosphate sodium STPP-0.35%

5. yellow soda ash-0.17%

6. water glass-0.2%

7. fluorescent brightening powder-0.05%

8. spices trace

9. water ratio 43%

The present invention makes by the following method:

In reactor with the urea of 37% formaldehyde solution and nitrogen content 46% mixed by 300: 600, stir with 80 rev/mins speed, treat urea dissolving back (generally being cooled to below 10 ℃), the sodium hydroxide solution that is added dropwise to 1N concentration is heated to 60 ℃ of insulation reaction after one hour to pH value=8, treats solution displaing yellow transparence, the cellulose solution 150 that adds 1: 10, mix postcooling to 20～25 ℃ of room temperatures, the dilute sulphuric acid 500 that adds 1.3% concentration then reacts, and reaction promptly comes to an end.This liquid is dewatered, remove mother liquor, its filter cake carrier that promptly is as the criterion.Accurate carrier is put into baking box, and to be baked to water ratio under 105 ℃ ± 2 temperature be to pulverize below 1%, promptly become carrier to standard sieve 35 orders, following material 3% nonionogenic tenside (6502) 2% anion surfactant A.B.S.3.5% tripoly phosphate sodium STPPs, 1.7% water glass, 1.7% yellow soda ash, 2%C.M.S, 1.5% sodium sulfate, 0.5% fluorescent brightening powder and spices trace are dissolved under 40 ℃ of low-grade fevers by top order in 250 the distilled water.With this solution be sprayed on the carrier finished product, purchasing finishes.

When this dry cleaning composition uses this finished product directly is sprinkling upon on carpet or the pile fabric, general consumption is 50g/m ²About (the dirty clean degree of looking fabric is regulated), with dried hairbrush or the electronic blanket machine of washing, as linear reciprocating carpet washing machine (about bowheaviness 5000g), do brush twice by 500 times/minute speed, add powder at the emphasis Polluted area and mend brush one time, leave standstill about 20～30 minutes, get final product with the suction cleaner absorption.

Claims

1, a kind of new powdery carpet and the prescription of pile fabric dry cleaning composition, having has tangible cleanup action to common stain on the various pile fabrics.The invention is characterized in to utilize and be wrapped with the carrier of the macromolecular organic compound methyne urine with adsorptivity and wear resistance of plant paper pulp as washing composition, the various auxiliary agents of tensio-active agent are coated on the carrier, thereby made the dirt removal on the carpet and rinsing is disposable finishes.
