Leather Breathability Testing Ensuring Comfort and Hygiene in Clothing

Product Description

Principle

Under a certain test temperature, a constant humidity difference is generated between two sides of the test specimen. The water vapor permeates through the specimen and into the dry side. By measuring the weight changes of the test dish in different time, water vapor transmission rate and other parameters can be obtained.

Standards

This test instrument conforms to the following standards:
ISO 2528, GB 1037, GB/T 16928, ASTM E96, ASTM D1653, TAPPI T464, DIN 53122-1, JIS Z0208, YBB 00092003

Applications

This instrument is applicable to the determination of water vapor transmission rate of:

Basic Applications
Films Including plastic films, plastic composite films, paper-plastic composite films, geomembranes coextruded films, aluminized films, aluminum foils, aluminum foil composite films and many others
Sheeting Including engineering plastics, rubber and building materials, e.g. PP, PVC and PVDC
Paper and Paper Board Including paper and paper board, e.g. aluminum foil paper for cigarette packages and Tetra Pak materials
Textiles and Nonwovens Including textiles and non-woven materials, e.g. waterproof breathable fabric, non-woven fabric for diapers and hygienic products
Extended Applications
Artificial Skin Artificial skin has to meet standard requirements for water vapor transmission rate to ensure better breath performance. This instrument can be used to test  water vapor permeability of artificial skin
Medical Products and Accessories Including plasters, aseptic wound protecting films, face masks and scar sticks
Solar Back-Sheets Including solar back-sheets
LCD Monitor Films Including LCD monitor films
Paint Films Test water vapor permeability of various sorts of paint films
Cosmetics Test water vapor permeability of cosmetics
