Coated fabric component detection method

Abstract

The invention relates to the technical field of textile, and discloses a coated fabric component detection method which comprises the following steps: 1, pretreatment: putting cloth to be analyzed into a washing machine for cleaning, cutting the cleaned cloth into cloth blocks with fixed sizes, and putting the cloth blocks into a constant-temperature and constant-humidity box for pretreatment; 2,preparing a density gradient solution, and 3, analyzing components: preparing the cloth into small balls, putting the small balls into the density gradient solution, and measuring the density of the cloth according to the suspension positions of the small balls after the small balls are balanced so as to judge the components of the cloth. According to the coated fabric component detection method,the adopted detection method can obtain the component composition of the fabric only through a simple physical mode, and is suitable for some small laboratories or laboratories of some fabric use enterprises, and through a simple method and component composition a user can better understand the performance of the cloth, and the cloth is used according to the characteristics of the cloth.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a method for detecting components of coated fabrics. Background technique [0002] A coated fabric is a textile in which a coating-bonding material has been applied in situ in a single or multiple layers on one or both sides of the fabric. Consisting of two or more layers of material, at least one of which is a textile and the other is a completely continuous polymer coating. [0003] When the coated fabric is used, a simple composition analysis of the underlying textile fabric is required for better use. [0004] Chinese patent (notification number: CN103091415A) discloses a method for identifying the blended components of two-component blended fabrics containing polyester and measuring the content of each blended component: the two-component blended fabric sample containing polyester is cut into pieces, and quartz sand is used as Solid mass dispersant, using pyrolysis gas ch...

[0004] Chinese patent (notification number: CN103091415A) discloses a method for identifying the blended components of two-component blended fabrics containing polyester and measuring the content of each blended component: the two-component blended fabric sample containing polyester is cut into pieces, and quartz sand is used as Solid mass dispersant, using pyrolysis gas chromatography-mass spectrometry to measure the pyrolysis spectrum of two-component blended fabric samples containing polyester, and qualitatively characterize the blended fabric samples according to the characteristic cracking peaks of different fibers, and then determine that only appears in polyester The characteristic cracking peak is the quantitative peak, and the peak area of ​​the quantitative peak in the two-component blended fabric sample containing polyester is determined by gas chromatography. The quality of the polyester is taken as the abscissa, and the peak area of ​​the corresponding characteristic cracking peak of the polyester is used as the vertical coordinate to make a standard curve, according to the standard curve and formula (1) to calculate the percentage of polyester in the sample, and then obtain the percentage of another component; the present invention is easy to operate, environmentally friendly, can effectively save experimental time and simplify experimental steps, but the method of the device Too complex for simple fabric analysis
