Quantitative analysis method of PVC (Poly Vinyl Chloride) film-covered fabric

Abstract

The invention relates to a quantitative analysis method of PVC (Poly Vinyl Chloride) film-covered fabric, comprising the steps of dissolving the fabric containing a PVC covering film by using a solvent, firstly carrying out qualitative detection on the PVC covering film, then dissolving or swelling the PVC covering film by using an appropriate solvent to strip from the base cloth and obtaining the content of the PVC covering film. The method disclosed by the invention has the advantages that a scientific and accurate quantitative detection analysis method is provided for the PVC film-covered fabric; and the problems that as part yarns or fibers are wrapped and covered by the covering film in the coating process of the production process of the fabric, the fiber content cannot be accurately analyzed and the qualitative quantitative detection of the covering film content cannot be carried out are solved. The method is suitable for the inspection of the film-covered fabric and products thereof, is scientific and objective in conclusions and capable of guaranteeing the scientificity and the fairness of detection results.

Description

(1) Technical field [0001] The invention relates to a measurement and analysis method in the field of textiles, in particular to a quantitative analysis method for PVC-coated fabrics. (2) Background technology [0002] Polyvinyl chloride (PVC) coated fabric products, with the application of high-tech in recent years, its quality and performance have been gradually improved, after years of development, it has been widely used, not only widely used in textiles and clothing, but also widely used in bags , shoes and hats, upholstered furniture, etc., the application range is very wide. [0003] With the widespread use of polyvinyl chloride (PVC) coated fabrics, the detection and labeling of the content of such products has become difficult. Since the authorization of professional inspection centers at all levels in my country is divided according to different industries, there is a saying that leather inspection does not care about fabrics, and fabric inspection does not care a...

Problems solved by technology

[0005] The current national standard and national method standard GB / T2910 quantitative chemical analysis method for two-component fiber blended products is a chemical analysis method for fiber fabrics. Due to the production process of vinyl chloride (PVC) coated fabrics, some yarns in the coating process Or the fiber is covered with a film, resulting in an inaccurate analysis of the fiber content and qualitative and quantitative detection of the film content, which cannot be adapted to the inspection of film-coated fabrics and products, resulting in the inspection reports issued by many inspection centers only for the content of the base fabric, and the conclusion is not accurate. Scientific, not objective, seriously affecting the scientificity and fairness of the test results
