Problems solved by technology
[0005] The technical problem to be solved by the present invention is that, aiming at the defects that the existing methods and systems for measuring the formaldehyde content of fabrics adopt optical methods, which are time-consuming, inconvenient, and high in cost, a method is provided to convert the formaldehyde content of the container by setting a conversion database. A method and system for measuring fabric formaldehyde content by converting the concentration into fabric formaldehyde content. The method and system do not use optical methods, the test time is short, the test method is simple, and no consumables or reagents are required for measurement

Embodiment Construction
[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0028] exist figure 1 In the flowchart of the first preferred embodiment of the method for measuring the formaldehyde content of fabrics shown in the present invention, the method for measuring the formaldehyde content of fabrics starts at step 100, and then executes:
[0029] Step 101, the airtight container 1 receives formaldehyde emitted from the surface of the fabric, while the formaldehyde response module 2 absorbs and consumes the formaldehyde in the airtight container 1;
[0030] Step 102, the formaldehyde response module 2 converts the formaldehyde concentration information in the airtight...

The invention relates to a method for measuring the content of formaldehyde in fabrics, comprising the following steps: S1, an airtight container receives formaldehyde that emits from the surface of fabrics, and simultaneously a formaldehyde response module absorbs and consumes formaldehyde in the airtight container; S2, the formaldehyde response module converts concentration information of formaldehyde in the airtight container into an electric signal; and S3, the electric signal is converted into the formaldehyde content of the fabrics according to the electric signal and a conversion database. The invention also relates to a system for measuring the content of formaldehyde in the fabrics. Without the adoption of an optical method, the method and the system for measuring the content of formaldehyde in fabrics have advantages of short measuring time and simple measuring method, require no consumable or reagent for measurement, and avoid the defect that the optical method adopted by original method and system for measuring the content of formaldehyde in fabrics are time-consuming, are not convenient and require high cost.
Description
technical field [0001] The invention relates to the field of measurement, more specifically, to a method and system for measuring the formaldehyde content of fabrics. Background technique [0002] Because formaldehyde is a gas harmful to the human body, the measurement of formaldehyde concentration in people's daily activities is essential. Many cities and organizations legislate or recommend maximum levels of formaldehyde in items that people can touch and acceptable levels of formaldehyde in enclosed spaces such as shopping malls, homes, and offices. [0003] There are generally two methods for measuring formaldehyde concentration: closed box method and extraction method. In the closed chamber method, described in ISO 15234 (Paints and varnishes - Tests for formaldehyde coatings and melamine coatings - Determination of formaldehyde concentration in a small laboratory), a closed chamber is covered over the material being tested , this method measures the formaldehyde emit...
