On the label of clothes, the composition of the fabric will be marked, among which "nylon" appears more frequently. Commonly speaking, nylon is what we often call "nylon", which has the advantages of good wear resistance and high resilience. However, a physical indicator that affects people's wearing comfort is breathability.
The "WPT-304 Water Vapor Transmission Rate Tester" developed by QINSUN Instruments was taken as an example to conduct a special test on the air permeability of nylon fabrics provided by clothing manufacturers. Through the detailed records of the test process, test results and other data, it provides a reference direction and method for the majority of enterprises in need.
1. Key words: water vapor permeability of textiles, nylon fabric moisture permeability tester, water vapor permeability tester, water vapor transmission rate tester, textile water vapor permeability, packaging water permeability tester, moisture permeability tester, resistance Moisture tester, water resistance testing machine
2. Implementation standards
GB/1037-88 "Plastic Film and Sheet Water Vapor Permeability Test Method Cup Method"
3. Test sample
Nylon textile fabric (note: the sample is provided by the customer of QINSUN instrument)
4. Testing equipment
The "WPT-304 Water Vapor Transmission Rate Tester" independently developed by QINSUN Instruments has met and complied with many international standards: GB/T 1037, GB/T 16928, ISO 2528, ASTM E96, ASTM D1653, TAPPI T464, DIN 53122-1, JIS Z0208, YBB00092003\
5. Test principle
WPT-304 water vapor transmission rate tester adopts the test principle of moisture permeable cup weighing method. At a certain temperature, a specific humidity difference is formed on both sides of the sample, and water vapor passes through the sample in the moisture permeable cup. On the dry side, the parameters such as the water vapor transmission rate of the sample can be obtained by measuring the change in weight of the moisture-permeable cup with time.
The "WPT-304 Water Vapor Transmission Rate Tester" developed by QINSUN Instruments adopts the principle of weighing method and can measure 3-6 samples at a time. The data is accurate and reliable. Therefore, it is an ideal testing instrument for major textile manufacturers, quality inspection agencies and other related enterprises and institutions.
Of course, for textile fabrics such as nylon, the water vapor transmission rate is only one of the testing indicators. In addition, there should be testing of tensile strength, thickness, impact resistance, tear resistance and other indicators, and non-standard customization is more acceptable. .
QINSUN Instruments has been committed to providing cost-effective total solutions for customers in most countries. The core purpose of the company is to continue to innovate and create high precision testing instruments to meet the quality control needs of different customers in the industry, and we look forward to improving communication and cooperation with enterprises and institutions in the industry.
