4.1 Coordination between needle, thread and sewing
material
Please use needle DP 17,Nm125-180.The coarseness
of needle should be in accordance with the nature of
material. If stitch on heavy duty material with a slim
needle, the needle will be easily bent, skip or thread
breakage occurs, on the contrary, stitch on tightly woven
material with a very coarse needle, the material will
be destroyed with over-big needle. So the needle and
thread should be properly selected.
