Description
Technical field
The invention belongs to product quality detection field, be specifically related to the high flux method for quick limiting the use of Determination of Residual Organic Solvents in a kind of textile.
Background technology
Textile arranges from raw material production and processing to finished product and all inevitably uses a large amount of organic solvent.Existing a series of laws and regulations forbid using the poisonous and hazardous organic solvent of part at textile in the world, be included in process of manufacture and prohibit the use, must not remain on the final product, or on final products, volatilizable organism must not exceed the different statement such as a certain Limited Doses.
The organic solvent that in current textile, regulation limits the use of mainly contains amide solvent, glycol ethers solvent and 1-METHYLPYRROLIDONE solvent.Within 2003, European Union 2003/36/EC instruction is by following material: formamide, N-METHYLFORMAMIDE, N-methylacetamide, N, dinethylformamide, N, the materials such as N-dimethyl acetamide, ethylene glycol monomethyl ether, ethylene glycol ethyl ether, glycol dimethyl ether, diethylene glycol dimethyl ether are listed in REACH instruction restricted substances list, are classified as the inventory of the 2nd class genotoxicity material.Amide solvent (totally 3 kinds), glycol ethers solvent (totally 5 kinds) and 1-METHYLPYRROLIDONE are listed in from year Dec in Dec, 2010 to 2012 and are shown great attention to material SVHC inventory by Europe chemical balance motion office (ECHA) successively, specify that such material could need use through authorizing.International Textile ecological study with detect association issue 2012 ecological textile attestation standard (Oeko-TexStandard100) by N, the Determination of Residual Organic Solvents such as N-dimethyl acetamide and 1-METHYLPYRROLIDONE are listed in sensing range, within 2013, increase N newly again, dinethylformamide, and the requirement of proposition limitation is: 0.1%.
Therefore, need the timely detection technique with independent intellectual property right of setting up badly and limit the use of Determination of Residual Organic Solvents for multiple in mensuration textile, realize textile at the security control produced and in circulation.
Organic solvent is limited the use of, the existing detection method of part for above-mentioned.The people such as Cheng Qun detect with DMF in the ultrasonic extraction textile of methylene chloride, gas chromatograph-mass spectrometer (GCMS), and detection limit can reach 0.5mg/kg.The people such as Xiang Zhongchao set up the detection method of dimethyl formamide and dimethyl acetamide in high effective liquid chromatography for measuring workshop air, for environment measuring and hygienical evaluation.The people such as Lian Qiuyan are by the ultrasonic extraction of methyl alcohol to the hexylene glycol monomethyl ether in textile and ethylene glycol monoethyl ether, and adopt mass spectrometer to carry out analysis and measure, method detects and is limited to 2.0mg/kg ~ 3.5mg/kg.The people such as Kong Xiangwei adopt Headspace-Gas Chromatography Analysis to detect the residual quantity of DMA and 1-METHYLPYRROLIDONE in textile, and detectability is respectively 6.8mg/kg and 11.6mg/kg.The people such as Cheng little Yan establish the high performance liquid chromatography-series connection quadrupole rod measuring method of mass spectrum of 1-METHYLPYRROLIDONE in the gentle sample of water.
There are following three problems in current prior art: 1. issued relevant laws and regulations limits the use of some organic solvent in textile both at home and abroad, but also there is no corresponding detection method at present, as formamide, N-METHYLFORMAMIDE, N-methylacetamide, glycol dimethyl ether, ethylene glycol diethyl ether etc.; 2. existing method can not carry out Simultaneously test to the multiple organic solvent that limits the use of at present.Because the physicochemical property of various organic solvent is different, be difficult to carry out effective qualitative and quantitative analysis in same detection method.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art, sets up a kind of multiple method limiting the use of organic solvent Simultaneously test in textile, and the security performance being applied to textile product detects.
The invention provides the method for quick limiting the use of Determination of Residual Organic Solvents in a kind of textile, utilize extractant to extract, extract gas chromatography-mass spectrum measures.
Further, limit the use of organic solvent in the textile that the present invention limits and comprise formamide, N-METHYLFORMAMIDE, N-methylacetamide, N, dinethylformamide, DMA, ethylene glycol monomethyl ether, ethylene glycol ethyl ether, glycol dimethyl ether, diethylene glycol dimethyl ether and 1-METHYLPYRROLIDONE.
Further, the concrete technical scheme of the present invention is as follows:
(1) configuration standard solution: with extractant as solvent, dissolved by the standard items limiting the use of organic solvent, thus preparation becomes the standard working solution of certain gradient;

A) testing sample is cut into 5cm × 5cm, then accurately takes testing sample 1g, and in testing sample, add the extractant of 10 ~ 30ml, then extract in extraction equipment, filter and be extracted liquid;
B) by steps A) extract of gained, at bath temperature is 20 ~ 70 DEG C, reduced pressure concentration, again after drying up, obtains concentrated residue;
C) by step B) residue obtained use 1 ~ 10ml extractant fully dissolves, and the sample liquid of gained, with after 0.45 μm of membrane filtration, obtains testing sample solution;
(3) gas chromatography-mass spectrometry analysis condition is:
Chromatographic condition: middle polarity chromatographic column; Injector temperature, 230 DEG C, Splitless injecting samples; Temperature programme, initial temperature 60 DEG C, keeps 2min, with the ramp to 260 DEG C of 20 DEG C/min, keeps 5min; Carrier gas is helium, and purity is 99.999%, 1mL/min constant current; Mass Spectrometry Conditions: transmission line temperature, 230 DEG C; Ion gun adopts EI source; Ion source temperature is 250 DEG C; The ionization energy is 70eV; Level Four bar temperature, 200 DEG C; Sweep limit is 35 ~ 350amu;
(4) drawing standard curve
The mixed standard solution prepared in (1), carry out gas chromatography-mass spectrum detection successively from low to high according to concentration, parameter synchronization rapid (3), with regulated substance chromatographic peak area for horizontal ordinate, regulated substance concentration is ordinate, drawing standard curve;
(5) measure
Detect when instrument indices reaches after mensuration requires, accurately sample solution 1 μ L injection gas chromatography-mass spectrum to be tested is detected, parameter synchronization rapid (3), reference standard curve, qualitative features ion according to retention time and correspondence carries out qualitative, carry out peak area quantification calculating according to quota ion, using signal/noise ratio S/N=3 as detection limit, S/N=10 is as quantitative limit.
Further, described extractant is selected from methyl alcohol, ethanol, acetone and acetonitrile; Be more preferably methyl alcohol.
Further, described extraction equipment is selected from ultrasonic extraction instrument, soxhlet extraction instrument and microwave extracting apparatus; Be more preferably ultrasonic extraction instrument.
Further, the extraction conditions in step (2) is in the ultrasound wave of 30 ~ 45kHz, ultrasonic extraction 10 ~ 60min at bath temperature is 20 ~ 70 DEG C, filters and is extracted liquid.
