Description
Technical field
The utility model relates to a kind of formaldehyde fast detecting instrument, relates in particular to a kind of quick detection kit that is applied to free formaldehyde in textile and garment products.
Background technology
Formaldehyde is widely used as finishing agent in fabric printing, its purpose mainly is to improve the permanance of auxiliary agent on fabric by nucleophilic and cross-linking reaction, because it can combine with the cellulose fibre hydroxyl.Its usable range comprises resin finishing agent, colouring stabilizer, water-proofing agent, softening agent, and bonding agent etc. are as in order to cellulose fibre being the crosslinking chemical of main fabrics for shrinkage, wrinkle resistant and wash and wear arrangement.Because the widespread use of formaldehyde, people touch formaldehyde through regular meeting in daily clothing, food, lodging and transportion--basic necessities of life.In textile, some finishing agent is directly to be that raw material is synthetic with formaldehyde, and formaldehyde not only can improve the colour fastness of textile coating, and can make the bright in colour beautiful of textile garment, keeps the permanance of stamp, dyeing.Because many finishing agents are that reversible chemical reaction is so the free formaldehyde release of these auxiliary agents self causes the formaldehyde that contains on the fabric to exceed residual quantity.Also can obtain proof in actual detected, after the processing of crease and shrink resistance, the content of formaldehyde value is relatively all than higher as the non-ironing trousers of cotton textiles, cotton textiles, polyester-cotton blend, flax, ramie cotton shirt, shrinkproof, wrinkle resistant do good more of this series products, and content of formaldehyde is just high more.The reason that causes formaldehyde to exceed standard in addition also has enterprise not have the importance of PARA FORMALDEHYDE PRILLS(91,95) content to cause enough attention, and lacks necessary check and control device, and enterprise only pays attention to the fiber content, pattern, quality of lining itself etc. when ordering lining.
When people's dress contained the clothes of formaldehyde, free formaldehyde produced intense stimulus by human respiratory tract and skin, and concentration causes when low that respiratory inflammation and skin disease, concentration Gao Shihui cause the tissue sudden change and bring out cancer.Formaldehyde can also reduce superoxide dismutase in the human body, make body produce stress situation and lipid peroxidation, thereby cause the decline of histocyte damage and immunity function, simultaneously neurobehavioral functions such as memory, notice, perception velocities are also had to a certain degree influence.
For this reason, developed countries such as America and Europe, Japan have stipulated that in succession the residual of formaldehyde limit the quantity of; The state compulsory standard GB18401-2003 of OeKo-Tex standard 100 and China's issue, residual limiting the quantity of to formaldehyde in the textile made clearly regulation: infant article must not be greater than 20mg/kg, directly the textile of contact skin must not be greater than 75mg/kg, and the textile of non-direct contact skin must not be greater than 300mg/kg.
The conventional method of measuring content of formaldehyde in the textile is generally used large-scale instrument at present.Its major advantage is detection sensitivity height, quantitatively accurate, but the determination step complexity is time-consuming, proving time long, labour intensity is big and mensuration expense height, so be difficult for popularizing.Acetylacetone colorimetry is mainly used in the detection of formaldehyde in the textile at present.In operating process, must be during immersion at (40 ± 2) ℃ water-bath (60 ± 5) min, must in the water-bath of same temperature, place 30min again chromogenic reaction is finished, survey again after cooling off 30min then; And in immersion process must every 5min shake soak sample conical flask once, adopt the absorbance at spectrophotometric determination 412nm wavelength place at last.Its major defect is: 1. operation is wasted time and energy, and work efficiency is lower; 2. be not suitable for carrying out in the routine work analysis of fabric sample in enormous quantities; 3. need to use large-scale instruments such as spectrophotometer, be not suitable for on-the-spot the detection; 4, testing cost is higher.
So current be necessary to develop a kind of easy and simple to handle, result rapidly, reliable cheap formaldehyde device for fast detecting with strong points, be convenient to enterprise, the public uses voluntarily.
