3 PRINCIPLE OF THE METHOD
3.1 Qualitative
Use of polyolefin elastic fiber in appearance form, solubility, and infrared spectra characteristics of qualitative identification textiles polyolefin elastomer
fiber.
3.2 Quantitative
The use of elastic polyolefin fibers and other fibers solubility differences in different solutions, to other soluble fibers, elastic polyolefin fibers collected
Victoria, washed, dried and weighed to calculate its share of the dry mass of the mixture with a percentage of mass corrected by the difference between the results of other fibers
content.
NOTE: If you manually separate mixtures fiber components feasible, priority can be manually decomposition.
