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

blend-testing


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.
