Description

The use in washing machine standard protein pollutes the preparation method of cloth

Technical field

The present invention relates to the manufacture craft that a kind of standard protein for the washing machine Performance Detection pollutes cloth, particularly test the making that cloth is polluted in the special use of washing machine washing (-)off properties, belong to standard and pollute the cloth technical field.

Background technology

At present, China's washing machine industry is in an autonomous innovation, flourish period.Competition between enterprise has entered the white-hot stage, finally sums up in the point that the competition of properties of product.The primary performance of washing machine is the power of washability.All the time, all adopt the artificial pollution cloth of making to simulate the power that true spot is estimated washability in the industry.So the artificial quality quality of polluting cloth of making has very big influence to the power of estimating the washing machine washability.

Abroad artificial manufacturing is polluted research starting that cloth simulates true spot early, and carried out system and deep research has entered the mechanization volume production stage.At present, the pollution cloth technology that Swiss Confederation's material science and technology experiment chamber (EMPA), German washing technology research institute (WFK) and Holland (CFT) produce is skillful, and steady quality occupies the international cloth market overwhelming majority share of polluting.

The domestic research that cloth is polluted in artificial manufacturing is started late, and studies still thoroughly inadequately, is in the laboratory theoretical research stage mostly.It is more skillful that the GB/T4288 GB carbon black with independent intellectual property right that China Household Electrical Appliances Research Institute produces pollutes cloth technology, and quality is more stable, has entered the suitability for industrialized production stage, represented the highest level of homemade pollution cloth, but mechanization degree is lower.At present, it is single that the cloth kind is polluted in homemade artificial manufacturing, seriously restricted the development of washing machine.Therefore, researching and developing novel pollution etamine making process is the only way out.

Summary of the invention

Scourability is the most important performance of washing machine.The kind of the scourability of overall merit washing machine and artificial contamination's cloth and quality have very big relation.The scourability of the multiple pollution cloth of American-European washing machine industry application overall merit washing machine adopts single carbon black pollution cloth to estimate and domestic washing machine industry is general.Process reform of the present invention domestic washing machine industry adopt single pollution cloth to estimate the situation that washing machine is cleaned rate.

Technology of the present invention solves the technical scheme that its technical problem adopts: the roll-in time of the nip pressure of various components in proportions, printing and dyeing machine and printing and dyeing machine in the control protein contamination liquid, its manufacturing process can be divided into following steps:

(1) place demineralized water and soap flakes in container, wherein soap flakes concentration is 1.25g/L;

(2) destarch: container to the water of heating steps (1) seethes with excitement, and cloth is dropped in the container handle, and the processing time is 10min;

(3) cloth after the destarch is carried out rinsing with demineralized water, rinsing time 3min, rinsing number of times 2 times;

(4) cloth cutting: the cloth that will dry is cut into (480 ± 2) mm * (500 ± 2) mm cloth on request;

(5) cloth flatiron: the some cloths of step (4) gained are piled up neatly, and the electric iron temperature controller is arranged on the cotton shelves, and temperature is 250 ℃, by a clean white lining cloth every cloth is soaked the ironing of two sides, back;

(6) cloth drying: after the some cloths of pressing of step (5) gained are wrapped with a clean white lining cloth, be placed on and carry out drying in the drying box and handle, the drying box operating temperature is 105～110 ℃, and be 3h drying time;

(7) preparation protein contamination liquid, wherein composed as follows:

Milk powder: 15～25 parts by mass, egg: 10～30 parts by mass, gum Arabic: 1～4 parts by mass,

Carbon black: 5～10 parts by mass, deionized water: 1000～3000 parts by mass;

(8) printing and dyeing: the protein contamination liquid for preparing is poured in the dyestuff groove, the cloth that cuts is immersed in the dyestuff groove, cloth was at the uniform velocity proposed from contaminated liquid in 3 seconds, place on the roll of dyeing apparatus, press 5 cycles; The cloth of roll-in is immersed in the dyestuff groove again, cloth was at the uniform velocity proposed from contaminated liquid in 3 seconds, place on the roll of dyeing apparatus, press 5 cycles; Take off cloth, be placed in the drying chamber and dry.

Beneficial effect of the present invention:

The invention has the beneficial effects as follows that having changed domestic washing machine industry adopts a plurality of single pollution cloth to estimate the present situation that washing machine is cleaned rate respectively, makes the evaluation of the clean rate of washing machine more perfect.The yield rate that the invention enables protein contamination cloth to make brings up to 90% by 50%, the protein contamination Bu Seze that makes is even, surfacing, reflectivity is in (20-50) % scope, clean rate is 0.2～0.5, adopts pollution cloth of the present invention can estimate the clean ability of washing machine fully according to GB/T4288-2008.
