Introduction:
The global spinning industry is currently undergoing big changes, not least towards the use of more modem and faster spinning machinery and computer system. These high-speed machines require much cleaner raw material, and therefore they constantly challenge the testing machinery developers to provide faster and more accurate testers and quality controllers. The equipments described in this report are mainly related with cotton spinning testing lab.

Factory location: DELTA spinning mill, Konabari, Gazipur

Objects:

1. To know about different types of machine used in spinning lab.
2. To know about the specification of different types of textile testing machine.
3. To know about their function.
4. To know about the special purpose of different machine.
5. To know about the machines, which are necessary to develop a good quality control lab (Spg ).

Quality assurance testing equipments in DELTA spinning mill’s lab:

Machine No-01: USTER HVI SPECTRUM

Specification of machine:

• Machine name-USTER HVI SPECTRUM
• Company-Zellweger USTER
• Country – Switzerland
• Software – USTER HVI 1000

Already published another article on USTER HVI 1000: Principles of Fiber Testing

Machine No-02: USTER AFIS PRO

Specification of USTER AFIS PRO:

Function:
The function of this machine is to measure different information about cotton and sliver

Description:
The USTER(R) AFIS PRO comes with different modules e.g. NC module, L & M module and T module.

The NC module measures the following:

• Neps count per gram – nep Cnt/g
• Nep size [micron] – nep size[µm]
• Seed coat nep count per gram – nep Cnt/g
• Seed coat nep Size [micron] – SCN [µm]

The L & M module measures the following:

• Mean length by weight – L(w)
• Length variation by weight – L(w) CV%
• Upper Quartile length by weight – UQL(w)
• Short fiber content by weight – SFC(w)
• Mean length by number – L(n)
• Length variation by number – L(n) CV%
• 5%-Length by number – L(n) 5%
• Short fiber content by number – SFC(n)
• Fineness [militex] – FINE [mtex]
• Maturity ratio – MAT
• Immature fiber content [%] – IFC [%]

The T module measures the following:

• Dust count per gram – Dust Cnt/g
• Dust size [micron] – Dust size[µm]
• Trast count per gram – Trast Cnt/g
• Trast size [micron] – Trast [µm]
• Visible Foreign matter [%] – VFM [%]

Machine No-03: USTER TESTER- 5

Specification of USTER TESTER 5:

Functions:

• Capacitive measurement of mass variations and imperfections in yarn, roving and
• Capacitive measurement of mass variations and imperfections in yarn, roving and sliver of staple fibers.
• Automatic check of all measured values, diagrams and spectrograms.
• Yarn classification based on the USTER

STATISTICS

• Measurement of foreign matters.
• Collection, evaluation and storage of measurement values.
• Quali Profile, graphic presentation of the overall quality.
• Filter functions for quick data retrieval and for the preparation of long-term reports.
• Simulation of yarn boards, woven and knitted fabrics.
• Editor for customizing report layouts.

Types of sensors used in USTER TESTER 5:
There are three types of sensors and work separately

1. Sensor-CS (It identifies the thick and thin place, UV% etc.)
2. Sensor-OH (It measure hairiness)
3. Sensor-FM (It measure amount of foreign matter which present in yarn)

Different test specification:

Sliver test:

• Taken sample: 50 to 100 meters
• Speed: 25 m/min
• Time: 1 minute
• Use sensor: CS only

Note: The test result will be accurate if the large sample is taken.

Roving test:

• Test speed: 50 to 100 m/min, 50 m/min maximum used
• Time: 1 minute
• Use sensor: CS and FM

Yarn test
Taken sample:

• Speed: 400 to 1000 m/min, 400 m/min maximum used
• Time: 1 minute
• Use sensor: CS, OH and FM

Machine No-04: USTER TENSOJET-4

Specification of USTER TENSOJET-4:

• Machine name-single yarn strength tester
• Company- Zellweger uster tester
• Origin – Switzerland

Function of the machine: The USTER TENSOJET-4 is used to measure single yarn strength

Technical data:

• Machine speed: 200 m/min (max 400 m/min)
• No of stock: 1-5, 00,000 but available used 200
• No of feeder: 24 bobbins

The machine shows the diagram of breaking force(N), elongation%, tenacity(cN/tex), breaking work (cN.cm) etc.

Test results of USTER TENSOJET-4:

Machine No-05: ZEIGLE LEA STRENGTH TESTER

Specification of Zeigle lea strength tester:

Function:
This machine is mainly used for measuring yarn strength.

Description:
First take a lee from the wrap reel machine and clamped in this machine, then run the machine according to set program. The gap between two clamps is increased and after sometime breaks the lee. At which load the lee is broke indicate in the display, it is shown into pound (lb). To find out CSP the load is multiplied with yarn count.

Machine No-06: ZEIGLE WRAP REEL(L232)

Specification of Zeigle wrap reel:

Function:
The main function of this machine is to prepare a lee for yarn count test

Description:
It is generally made of steel with a reel. The circumference of the reel is 54 inch and measure 120 yds of yarn then determines the yarn count.

Machine No-07: ZEIGLE WRAP BLOCK(L212)

Specification of Zeigle wrap block:

Function:
Use to measure the hank or count of preparatory process such as sliver, roving.

Description:
It is generally made of steel with a reel. The circumference of the reel is 36 inch and determines the length and weight by balance. Finally measure the weight/unit length.

• Length for sliver-6 yards
• Length for roving-30 yards

Remarks:
The THE DELTA SPINNING MILLS LIMITED is one of the 100% export-oriented mills in Bangladesh. The testing laboratory of this factory to maintain best quality product. For this reason, the modern machine is used in this laboratory. The general manager (Factory) who gave permission to enter in the factory. Beside this the general manager (Laboratory) and Sr. Quality officer also help to collect the necessary information about the testing equipments in those spinning lab. This knowledge will be helpful in future.
