Spiral needles

螺旋形针.jpg

Characteristic:

1: Equilateral triangle working position, after a specific twist;

2: The size of the hooks on all edges is the same.

3: Number of common hooks: 2 on each edge;

4: The arrangement of hook needles at work site is different from that of common needles.

Advantage:

1: More fibers can be grasped and needling efficiency is higher.

2: Different arrangement of hook and spur makes the final product have higher tensile strength and homogeneity (MD: CD ratio);

3: The surface quality of the final product is optimized.

4. Reducing puncture density can improve production speed.

5: Non-woven fabrics have better myopia.

6: Compared with the common needle, the twisted working position does not cause unfavorable bending fracture characteristics.

7: When using superfine fibers, the opening rate is higher.

Applications:

1: Automobile (visible area)

Specifications are available:

1: Aircraft number: 36-42

2: Needle length: 3", 3.5"

3: Spur type: RF

Other machine numbers, Crochet shape and needle length can also be provided as required.
