Functions or objectives of draw frame

Draw frame

Draw-frame is a process by which fiber is done to equalize, parallel, blend and dust remove. Production costs of the draw frame are less than 3% of the total yarn cost. But it has a great influence on yarn quality, especially on evenness. The draw frame is a guaranteed compensation point for removing errors. High-performance drawing frames currently produce 400 kg of sliver per hour in each distribution.

Functions/objectives of draw frame-

1. The main objective of the draw frame is equalizing.

2. One of the main tasks of the draw frame is improving evenness over the short, medium, and – especially – long term.

3. To get optimal value for strength in the yarn characteristics, the fibers must be arranged parallel in the fiber strand.

4. Creating this parallel layout is basically the work of the draw frame.

5. Draw frame fulfills this task by means of the draft since every drafting step leads to the straightening of the fibers.

6. For equalizing effect, doubling also provides a degree of compensation for raw material variations by blending, which occurs simultaneously.

7. Dust is steadily becoming a greater problem both in processing and for the personnel involved. It is important to remove dust at the most practical stage at each possible point in the overall process.
