Description
?
Technical field
The invention belongs to the assessment of articles for washing clean effect and detection technique field, be specifically related to a kind of preparation method who assesses with artificial spot sample that washs.
Background technology
The washing process of fabric is to have used interface phenomena complicated between spot-fiber-washing agent from microcosmic, and therefore, dirt character is very big to the correct evaluation influence of the detergency of various washing agent.The kind of dirt is a lot, almost has the how many kinds of material that how many kinds of dirt even more is just arranged in the world, and various dirt individualism seldom, and they usually are infected with jointly and are adsorbed on the fabric.Being difficult on the fabric be spot again with the dirt that conventional cleaning means are removed, is the idio-morphosis form of dirt.The difference of itself and dirt is that dirt can be washed solution and wash off when washing, and spot then can not be washed off or just can't be washed off at all fully.The same with fabric dirt, the kind difference of spot, it sticks form and sticks intensity different with fabric, and material and process means used when going to steep also should be differentiated.
Principal feature according to common textile stains can be divided into grease class, pigment, protein and colloid class etc., the evaluation method of common fabric detergent detergency has three kinds: the one, and the Actual laundering assessment, be about to end product to be washed and deliver to different consumers' uses, gather the result of consumer's Actual laundering and sum up the result of use of fabric detergent, finally according to clean result fabric detergent is provided the judgement of a reality.The 2nd, the laboratory simulation home washings, namely understand various Actual laundering customs by the mode of factual survey or questionnaire, analyze the back by statistics and carry out the washing evaluation test of fabric detergent at the similar environment of lab design, judged the clean result of fabric detergent by wash result.The 3rd, complete laboratory testing method, namely select people daily in the variety classes spot of normal appearance be coated in and make the test artificially soiled cloth on the fabric, its cleaning strength is judged the clean result of fabric detergent with fabric detergent.Said method respectively has relative merits, and the above two advantages are to approach with actual conditions, but the expense height, and process is longer, is unfavorable for that it applies.The latter is because expense is low, and the time is short, is easy to realize unified and popularization, can be extensive use of in general laboratory and production research unit, and shortcoming is with truth certain discrepancy to be arranged.
What GB GB/T13174-2003 " evaluation of fabric detergent scourability " adopted at present is the lab investigation evaluation methods, namely by selecting carbon black soiled cotton (JB.01), albumen soiled cotton (JB 1) and sebum soiled cotton (JB.03), the test fabric washing agent is to the clean effect of all kinds of spots under certain conditions, makes the result of washing agent detergency ability evaluation and conclusion more near detergent washing effect in the real life.
Along with development of science and technology, the raising of mode of washing mechanization degree, means and the mode of research fabric detergent decontamination evaluation are changing.Simulation artificially soiled cloth based on different spots also constantly is incorporated into the clean result evaluation and test, with the clean result of thoroughly evaluating Related product, makes experimental result can better reflect practical effect.And research and make the soiled cotton of novel kind, the special-purpose washing test equipment of exploitation will become one of key content of fabric detergent detergency test research from now on.The present invention comes therefrom.
Summary of the invention
Fundamental purpose of the present invention is to provide a kind of fabric sample preparation method of the fabric washing recruitment evaluation based on liquid spot, has solved the not good problem of spot sample repeatability in the prior art.
In order to solve these problems of the prior art, technical scheme provided by the invention is: the washing assessment is characterized in that with the preparation method of artificial spot sample, may further comprise the steps:
(1) design and choose suitable cloth sill,
(2) spot specimen preparation: with proper tools with the spot sample through mixing, stir, stablize homogenizing and prepare required liquid spot,
(3) the cloth sill is coated with stain and sample drying, ageing: the liquid spot sample that will prepare is coated with stain or dyes system the cloth sill, then with artificial spot sample by realistic simulation requiredly carry out drying, ageing is handled.
Preferably, described step (2) spot sample preparation steps is: prepare artificial spot liquid according to the kind of selecting spot for use, be placed on 4000r/min in the emulsifier～5000 r/min emulsification 1-3h, make artificial spot liquid stabilising homogenizing, spot liquid after the homogenizing is poured in the container, standby.
Preferably, described step (3) cloth sill is coated with stain and sample drying, aging step are: will be ready to the cloth sill and soak into fully in the spot liquid after a period of time, with small-sized printing and dyeing stitching roll extrusion 3-10 circle, take out and dry rearmounted oven ageing, preserve stand-by with plastic bag sealing.
Preferably, described aging temperature is 50 ℃-70 ℃, and the time is 2-6h.
Preferably, the assay method of liquid stain concentration is in the step (2): after the liquid spot that will extract is diluted to desired concn on request, pasting lining with undressed blank fiber is contrast, measures whiteness value by the spectrophotometric colour photometer and indicates affirmation spot concentration of specimens.
Preferably, the confirmation method that dyes effect processed in the step (3) is: use the comparison of spectrophotometric colour photometer to dye the colourity difference that system front and back sample whiteness value result presents, judge whether the artificial spot sample as the washing assessment meets the requirements.
Preferably, described cloth sill comprises fabric.
Preferably, described fabric is selected from multifilament and pastes lining.
Preferably, the middle surface-coated liquid spot of fabricbase of described step (2) is a kind of or its combination in grease class spot, pigment spot or the protein-based spot.
Preferably, described grease class spot comprises plant oil stain, mineral oil stain; Described pigment spot comprises acid look stain, fat look stain, colloidality look stain; Described protein-based spot comprises bloodstain, milk stain.
Plant oil stain in the described grease class spot is selected from Semen setariae oil or hydrogenated vegetable oil; The mineral oil stain is selected from shell Helix machine oil API:SL/CF or suitable person (viscosity SAE:10W-40); Acid look stain in the described pigment spot is selected from 0.05% erythrosine (C.I. 45430), sodium carboxymethyl cellulose (CMC-Na) 0.10%, honey 2～5% and is dissolved in 1 M acetic acid-sodium acetate buffer solution (pH value: 5.5); Fat look stain is selected from by 60% A-2175 synthetic resin (37%), 12% carbon black, 5% oleum sojae, 7% butyl glycol ether, 16% deionized water formulated; Colloidality look stain is for adding the burnt black ink of 1% gelatin; The bloodstain of described protein-based spot is that 5mL 0.02% erythrosine (C.I. 45430), 0.5mL 0.02% light blue (C.I.Food Blue 2), 1mL ethanol and 500mL corn syrup, 65mL 10% cornstarch, 65mL water are formulated; The milk stain is whole milk.Certainly, above-mentioned spot raw material can also be the substitute of other kind that can expect of the art personnel or the substitute in the known technology.
