Quality control for spinning

Quality of the yarn is maintained through different lab test in the spinning.

AFIS (Advanced Fiber Information System):
Sample weight taken for this test is 5 gm. Then this sample cotton is rolled up to 31 cm. then it is inserted to the machine. The tested parameters are HVI.

HVI (High Volume Inspection):

Different quality characteristics are measured from this test. These characteristics are mainly SCI (Spinning Consistency Index, Length, Amount of fiber, Uniformity, Short Fiber Index, Strength, Elongation, Moisture Content, Rd, +b, etc.

Yarn Twist Tester:
In this test, the TPI (twist Per Inch) is measured.

Count Measuring Balance:
In this test count is measured automatically by using a120 yards yarn as sample with the help of weight principle. Here 120 yards yarn is called 1 Lea.

Lea Strength Tester:
Through this test the strength of the yarn is measured. The following rule is used here:
C.S.P (Count* Strength*Product)= count* mass of yarn.

Uster Evenness Tester:
The properties which are measured from this test are as followes:
Single yarn strength
Count, count CV%
U%, CVm

Trash Analyzer:
In this testing the trash content (seeds, particles, leaves etc) in the fiber is measured.

Crimp Tester, to calculate the crimp in yarn affected by knitting or weaving by taking apart the yarn from a piece of given-length fabric, unbending it under given force and measuring its length, to determine actual yarn usage.
