300+ TOP DAE KNITTING ENGINEERS Interview Questions and Answers

DAE KNITTING ENGINEERS Interview Questions for freshers and experienced :-

1) Explain shedding?
Shedding is the act of dividing the warp threads according to design into two parts, to allow the passage of shuttle/weft inserting element from one side of the loom to the other.

2) List down/what are the types of shedding mechanism?

  • Paddle/treadle shedding (used in hand loom)
  • Tappet shedding (used in power loom)
  • Dobby shedding (used in power loom, at past used in hand loom)
  • Jacquard shedding (both hand & power loom are used now)
  • Combined shedding

3) Write down the faults of picking?

  • Early picking
  • Late picking
  • Smash or Bang-off
  • Short picking
  • Harsh picking
  • Shuttle flying out

4) List some abbreviations?

  1. PPM = picks per minute
  2. PPI = picks per inch
  3. EPI = Ends per inch
  4. RS = Reed space

5) List down the types of needle?

  • Latch needle
  • Bearded needle
  • Compound needle

6) List down the weft knitting elements?

  • Needle
  • Sinker
  • Cam

7) List the basic knitted structure?

  • single jersey or plain
  • 1×1 rib
  • 1×1 inter lock
  • 1×1 purl

8) Explain back loop?
The loop where heads are above and hanks are below is called back loop.

9) Explain face loop?
The loop where heads are below and hanks are above is called face loop.

10) Explain warp & weft crimp?
The waviness of the yarns due to interlacing of warp and weft in producing fabric is called crimp.

11) Explain weave?
Interlacement of the ends and picks with each other produces a coherent structure. The repeating pattern of interlacing is called the weave.

12) List down/Classify the types of sett?

  • Warp sett (No. of warp/inch)
  • Weft sett (no. of weft/inch)

13) Explain basic weave structures?
(i) Plain
(ii) Twill
(iii) Satin

14) Explain let-off mechanism?
To unwind the equivalent length of warp sheet from the warp beams with the progress of take-up during weaving.

15) Explain pick spacing?
The space occupied by a pick in fabric.

16) Explain function of take-up mechanism?
To wind the already woven fabric on the cloth roller with the progress of weaving.

17) Explain object of beat-up mechanism?
To push the newly inserted weft yarn (last pick) to the fell of the cloth.

18) Actual production of a m/c is always less than that calculated production?

19) Explain picking?
To propel the shuttle or any other weft inserting elements.

20) List the types of power loom?

  1. Modern/shuttle less loom
  2. Conventional/shuttle loom

21) List the types of loom?

  • Hand loom
  • Power loom

22) Explain sizing?
Sizing is the process of giving a protective coating on the warp yarn to minimize yarn breakage during weaving.

  • Weft stop motion
  • Warp protector
  • Weft protector

34) Explain secondary motion?
The secondary motion are as follows:

  • Let off
  • Take-up
