Introduction:
In textile industry, row stuff is the most dominant component since it contributes 50-75% of full manufacturing cost. Any errors or negligence inwards pick together with composition of raw stuff cannot move corrected yesteryear whatsoever means. Here omissions are beyond redemption.

In instance of spinning manufacture the basic raw material is fiber which has a really high marking of variability. Its standard is actually a tough draw of piece of job but it is oft said that if 1 tin mensurate it thence together with solely thence he tin create out it.

To discovery the fiber testing instruments together with physical care for nosotros stimulate got visited the Amber Cotton Mills, Banglabazzar, Gazipur which is a leading lift inwards the textile sector of Bangladesh. They make high character knit yarn using the latest machinery. There cotton fiber yarn is automobile conned together with spliced with the best modern machineries. The cotton fiber yarn is Usterised together with electronically cleaned. Amber has a consummate make of latest USTER testing laboratory equipments.

Theory:
The character of cotton fiber varies considerably alongside the dissimilar varieties available. It is non slow to define character inwards absolute terms. The most of import fiber properties which decide the character of cotton fiber are its fiber length, fineness, maturity together with strength.

Testing is a valuable assistance to those connected to the production, distribution together with consumption of textiles, if the instruments together with techniques are used effectively. The right class of activity may move taken from the results of testing. Hence it tin move said that the testing is a agency to an end.
Contribution of fiber properties to yarn character
Testing is useful inwards the pick of raw material, inwards the command of physical care for together with character of the production together with inwards the evolution of the process.

Testing is the application of technology scientific discipline noesis together with scientific discipline to the standard of the properties of textile fibers, yarns together with fabrics. It involves the usage of techniques, tools, instruments inwards the laboratory for the evaluation of the properties of these dissimilar forms of textiles.

Objects of the Assignment:
  1. To know almost diverse testing machines.
  2. To know almost the specifications of testing machines.
  3. To know almost diverse functions of testing machines.
  4. To net noesis almost Q/C department.
  5. To guess proper characters of diverse samples such every bit fiber, yarn, sliver.
  6. To assist diverse query for pick of raw material.
  7. For physical care for command & production control.

  2. Wrap Reel.
  3. Electronic Balance.
  4. Lea Strength Tester.
  5. Twist Tester.
  6. USTER HVI grand
  7. USTER AFIS PRO.

  10. Digital Splicing Strength Tester.
Wrap Block

Machine specification:
  • Name: Wrap block
  • Company: MAG
  • Origin: Republic of Republic of India
Function of the machine:
Used for making Sliver together with roving lea together with count determination.

Necessary parameter:
Sample length (For sliver) = vi Yards
Sample length (For roving) = xxx Yards
Weight unit= Weight both for sliver together with roving is measured inwards grain.

Testing principle:

For sliver

6 yards sample is taken

Wt of sample is measured inwards gr

Then the wt is divided yesteryear vi to become gm/yd

For Roving

xxx yards sample is taken

Wt of sample is taken inwards grain

Then 250 is divided yesteryear the wt of sample to become the hank of sample.


Experimental laid up:
Fig: Wrap block machine
Wrap reel

Machine specification:
  • Machine name: Wrap reel
  • Company: MAG
  • Origin: India
Function of the machine:
Used for making yarn lea together with count measurement.

Necessary parameter:
  • Sample length: 120 yards
  • Reel circumference: 1.5 yards
  • Revolutions for making 120 yards yarn lea: lxxx
  • Traverse length: 1.5 inch
Testing procedure:
120 yards sample is made yesteryear roll reel

Wt of sample is measured inwards gm

Then yesteryear adopting formula count is measured


Formula used:
Count (Ne) = 64.8/Lea weight inwards gram

Experimental laid up:
Fig: Wrap reel machine
Lea forcefulness tester

Machine specification:
  • Machine name: Lea forcefulness tester
  • Model No: EleStretch XT
  • Company: MAG
  • Origin: India
Function of the machine:
Used for determining the forcefulness of yarn lea.

Necessary Parameter:
  • Sample type: Yarn lea
  • Sample length: 120 yards
  • Clamp to clamp distance: 0.75 yards
  • Strength unit: CSP (Count Strength Product)
Testing procedure:

120 yards sample is taken yesteryear Wrap reel

Count is determined

Then sample is laid inwards machine

Machine is run

After the sample beingness broken the reading (breaking tension inwards lb) is taken

Then yesteryear adopting formula CSP is calculated

Formula used for calculating CSP:
CSP=Count (Ne) X Breaking tension (lb)

Experimental laid up:

Automatic twist tester

Machine specification:
  • Machine name: Automatic twist tester
  • Company: MAG
  • Origin: Republic of Republic of India
Function of the machine:
Used for checking the TPI inwards yarn.

Testing procedure:

20 inch sample is laid inwards machine

Respective dead weight is inserted

Machine run

After the yarn beingness completely untwisted the machine is automatically stopped gives reading inwards display that indicates the TPI

Experimental laid up:
Automatic twist tester
