Description
Technical field
The invention belongs to the detection technique field, particularly relate to a kind of textile disappear smelly performance detection device and detection method.
Background technology
At present, the increasing smelly textile product that disappears comes into the market, and people are also more and more to the demand of such textile, but ordinary consumer is difficult to distinguish authenticity of products.From protection consumers' rights and interests and environmental harmony factor, should implement the disappear research and the formulation of method of testing and relevant criterion thereof of smelly ability of textile as early as possible, make the smelly produce market transaction standardization that disappears, thereby protect consumer's legitimate rights and interests.
Current is textile one of the smelly detection methods that disappear at the widely used 6 grades of odor strength explicit representations of Japan, promptly through human body the sample smelly effect that disappears is passed judgment in the sense of smell of foul smell.This method is divided into 6 grades with foul smell: 1, odorless; The smell that 2, can perceive slightly (detection critical value); 3, can know it is the faint smell (cognitive critical value) of what smell; 4, the light smell of perception; 5, stronger smell; 6, strong smell.But because everyone sense of smell all has very big-difference, and receive the influence of health and hobby at that time, so deficiency in objective property.Therefore, in " stench prevents method ", numerous data are carried out statistical treatment, in the scope of odor strength 2.5～3.5, stipulated the limit value of composition (specific odorant) concentration and foul smell index.
Fitting and uncomfortable explicit representation, is the method that adopts with uncomfortable degree of fitting for exhibit flavour.At present be 9 grades and fit and uncomfortable explicit representations, promptly 1, extremely uncomfortable what Japan adopted; 2, very uncomfortable; 3, discomfort; 4, sense is uncomfortable slightly; 5, there is not special comfortable or sense of discomfort; 6, feel comfortable slightly; 7, comfortable; 8, as snug as a bug in a rug; 9, extremely comfortable.Consider individual difference and reliability, generally use as auxiliary data.Though in testing repeatedly, individual inner change is very little, can be heard the influence of flavor time length.
The mentality of designing of odor concentration explicit representation test is: the odorous gas of variable concentrations stimulates degree varies appearance to people's olfactory organ; Make the existence of judging stink to the people with certain density odorous gas earlier; If feel the existence of stink, then dilute odorous gas with air, judge to the people again; Move in circles, till imperceptible.The existence of imperceptible stink is then given tacit consent to odorous gas and is lower than a certain critical value, multiply by the concentration that extension rate then draws odorous gas.
The correlated performance index that olfactometry is measured odorous gas has important practical significance, it with people's actual life in consistent to the odorous gas sensory reaction, the information of closing to reality can be provided for disappearing of textile is smelly.But olfactometry relies on people's subjectivity to a great extent, deficiency in objective property, and can only make comprehensive evaluation to odorous gas, and can not accurately judge the odorous gas composition, cause smelly root thereby find out.
Summary of the invention
Technical matters to be solved by this invention provides a kind of textile disappear smelly performance detection device and detection method; Can carry out fast detecting to gas to be measured; Record the concentration of gas to be measured accurately and efficiently; Can measure reliably the textile smelly performance that disappears, the in time and accurately on-the-spot data that detect are provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of textile smelly performance detection device that disappears is provided; Comprise airbag, airbag valve, connecting pipe, glass tube, Gas controller; Described airbag is a rectangular outer frame; Wherein three limit sealings, another side can seal with sealing strip; Place textile to be measured in the described airbag; Described airbag is provided with an airbag valve; Described airbag valve links to each other with the glass tube front end through connecting pipe; Described glass tube rear end links to each other with Gas controller through another connecting pipe.

The inner filling of described glass tube colored indicator, outer wall is printed on concentration scale, and two ends seal with the welding mode, open just now before the use.
Described colored indicator is highly stable and can produces the compound of colour developing chemical reaction to gas to be measured that described compound can be preserved more than 2 years.
But described concentration scale range of readings is 0.25～200ppm.
Described Gas controller volume is 1.5～5L, and is furnished with gas sealing valve.
A kind of textile smelly performance detection method that disappears is provided; Use described a kind of textile smelly performance detection device that disappears; Its operation steps is following: the textile to be measured that, will prepare is put into the airbag of emptying, with sealing strip airbag is sealed, and opens the airbag valve; Charge into foul smell, close the airbag valve; Two, etc. textile to be measured adsorbs gas to be measured after the some time, opens gas valve, from airbag, extracts a certain amount of odorous substance with Gas controller, detects the residual concentration of gas to be measured, the reading of concentration scale on the sight glass pipe; Three, repeat two operation and adsorb gas to be measured up to textile to be measured and reach balance, record the residual concentration of gas to be measured; Four, calculate: the smelly rate %=that disappears (blank gas concentration to be measured-the remaining gas concentration to be measured in smelly back disappears)/blank gas concentration * 100% to be measured.
In the described step 1, the gas volume to be measured that charges into airbag can be 2～6L, and concentration can be 60～200ppm.
In the described step 2, three, from airbag, extract the operation of odorous substance detected gas residual concentration, the time interval can be 1h between per twice.
