Protein with fibers, polyester, nylon or acrylic
Blend test, polyester wool blend test, polyester nylon blend test, nylon acrylics blend test, nylon woollen blend test, lycra cotton blend test, lycra blend test,spendex(lycra) viscose blend test
In
this method, properly mixed mixed fibers are taken in Conical task and add 5%
(W / W) sodium hydroxide or potassium hydroxide solution to boil for 10
minutes. Protein fibers are dissolved in sodium hydroxide or potassium
hydroxide.
Fill
the remaining fibers and wash thoroughly with water and then wash it with
dilute acetic acid. At the end, they dry up and weigh the percentage of
proteins and other fibers
In
this method, weigh the composted fibers properly and heat it with meta cryssol . In this, polyester fibers are washed off and weigh the other insoluble
fibers thoroughly after washing and drying. In this way polyester removes the
percentage of fibers
Test blend with Elastane (Spandex or Lycra) cotton or viscose fibers:
In
this method, mixed fibers are D. M . F . ( DIMETHYL FORMAMIDE ) With action D. M . F . Elastican
dissolves in In this way, we are able to weigh the remaining fibers thoroughly
and weigh them and remove the percentage of elastane.
