Dear Ms. Smornwan,
unfortunately this problem is extremely serious.
Our client worked your yarn to produce tapes as the one we sent you. Now many of his clients are returning the final product due to flaws on the tape.
It is not just one item that presents the problem, but yarns with different numbers of filaments.
It is quite difficult to quantify the damage now, since flaws are visible only after working and sometimes only after dying, but sure enough damages will be huge.
We need to understand what the cause of this problem is and how we can solve the matter.
It would be useful if you could send a technician to examine the issue, as we need your guarantee that this will not happen again in the future.
Moreover, we had more complaints about your rubber lately. I am especially referring to Dear Ms. Smornwan,
one of our clients recently encountered problems with your rubber.
On the final product you can see some flaws, that is, stripings where the count of the rubber seems to be bigger with respect to the rest of the rubber.
I am sending you photos of the boxes that present this problem.
I am referring to Invoice 15E06001 dated 05/06/2015 and Invoice 15E05007 dated 20/05/2015.
I am also sending you sample of the final product by DHL, so that you can check.
Looking forward to your kind feedback.
Best regards,
