The ratio of the blend fibers
We know that
no single lace cloth can produce all the qualities like strength, comfortable
properties etc. It is therefore necessary that the properties of the need can
be obtained by mixing different fibers.
We know that
the strength in 100% polyester fibers is very high, but it is not
comfortable because it has very little moisture content. Therefore, if it is
mixed with cotton fibers then this reduction of polyester becomes complete. We
can mix different types of fibers based on the things given below.
1. Getting
different properties
2. According to
changing fashion
3. Considering
the price of fibers
It is very
important to know the ratio of fibers in different fabrics. Some ways to get
rid of the ratio of fibers to fabrics are given below.
Polyester and
Cellulose blend Fibers Test:
For this
Weighing .5 to 1.0 grams properly weighing the sample into a flask and
putting 75% percent (W / w) sulfuric acid (M: L, 1: 200) in it and it will be given an hourly water
bath at 50 +
5 degree
centimeter (Water bath). After this, the filtrate which is left is the
polyester. Wash it well with water and neutralize it with thin solution of
ammonia and weigh it by 110 drilling it on drying and cooling it. In this way, the
percentage of polyester is gone, and what remains of the percentage given by 100 is the percentage of cellulose (cotton or
viscose).
