涤纶印染布甲醛含量检测数据

对本公司印染加工的涤纶面料进行抽样检测，检测项目甲醛含量，甲醛含量是面料印染质量的重要指标，从而为涤纶面料质量分析评价提供事实依据。1.数据统计：随机抽取公司仓库的印染涤纶面料成品，抽样4米，备样2米，从样品上取两块试样剪碎，分别称取1g，精确至0.001g。2.数据处理：2块试样分别进行检测， 按以下公式计算待测样品的甲醛含量： F=c×100÷m，F为样品中的甲醛含量，mg/kg， c为用校正吸光度通过标准曲线计算的甲醛浓度，μg/mL，m为试样的质量，g，取两次检测结果的平均值为试验结果3.85，公式如下：涤纶甲醛含量=（样品1中甲醛的含量+样品2中甲醛的含量）÷2，根据GBT 2912.1-2009 《纺织品 甲醛的测定 第1部分：游离和水解的甲醛（水萃取法）》规定的检出限为20mg/kg，判定该涤纶甲醛未检出，单项判定符合。3.数据应用：纺织品中游离甲醛含量的测定旨在检测纺织品中游离甲醛的含量，确保生产出的纺织品符合国家和国际的相关标准要求，同时也能够保障消费者的健康安全。

Sampling and testing were conducted on polyester fabrics dyed and processed by our company, with formaldehyde content as the test item. Formaldehyde content is a critical indicator of fabric dyeing quality, providing factual evidence for the quality analysis and evaluation of polyester fabrics.
1. Data Statistics: Randomly select finished dyed polyester fabrics from the company's warehouse, with a sampling size of 4 meters and a reserve sample of 2 meters. Cut two test specimens from the sample, weigh 1g each with an accuracy of 0.001g.
2. Data Processing: Detect the two specimens separately, and calculate the formaldehyde content of each test specimen using the formula: F = c × 100 ÷ m, where F is the formaldehyde content of the single specimen (unit: mg/kg), c is the formaldehyde concentration calculated via the standard curve with corrected absorbance (unit: μg/mL), and m is the mass of the test specimen (unit: g). Take the average of the two test results as the final test result, which is 3.85. The calculation formula for the polyester fabric's formaldehyde content is: Polyester Formaldehyde Content = (Formaldehyde Content of Sample 1 + Formaldehyde Content of Sample 2) ÷ 2. According to the detection limit specified in GB/T 2912.1-2009 *Textiles - Determination of Formaldehyde - Part 1: Free and Hydrolyzed Formaldehyde (Water Extraction Method)*, which is 20 mg/kg, it is determined that no formaldehyde was detected in this polyester fabric, and the single-item judgment meets the requirements.
3. Data Application: The determination of free formaldehyde content in textiles aims to detect the free formaldehyde content in textiles, ensure that the produced textiles comply with relevant national and international standard requirements, and also safeguard the health and safety of consumers.
