Our factory purchased 500 kilograms of aramid yarn from Guangdong Caiyan Co., Ltd. in late March 2007 for weaving base fabric to produce high-temperature needle felt. Due to tight time and trust in Guangdong Caiyan Company, our factory put into production without conducting temperature resistance test on this batch of aramid yarn. After producing a batch of products, after testing, the temperature resistance did not meet the requirements, and it shrank by about 10% at 200 degrees. Therefore, the quality appraisal was submitted to Caiyan Company in mid-April and samples of aramid yarn were sent back.
One month after confirming that Caiyan received the samples, no clear answers and results were obtained. Our factory has no choice but to send samples for testing. After testing in the Southern Science and Technology Testing Center of the textile industry, the result was that the dry heat shrinkage rate of this batch of aramid 1313 yarn reached 6.5% under an environment of 204 degrees for one hour. There are serious quality problems.
Now Caiyan Company also agrees with this test report, admits that aramid yarn has quality problems, aramid yarn is processed outside, not spun by itself, and said that this product meets national standards and corporate standards. Afterwards, our factory asked Caiyan to show the enterprise standard and the national standard. They could not come up with these two standards for various reasons. Before this, Caiyan did not explain to our factory that aramid yarn has a heat shrinkage rate. Later, when we compared it with Yantai's aramid 1313 yarn, Yantai's heat shrinkage rate was 204 degrees. After working for an hour, there was no heat shrinkage. The product introduction of Caiyan Company above is able to work normally under the environment of 220 degrees, and the service life can reach ten years. This is quite different from the actual use of aramid 1313 yarn bought by our factory.
Now Caiyan Company puts forward suggestions on quality issues and compensates our factory for 10% of this batch of goods, which is offset by the goods. In this regard, it is impossible for our factory to purchase raw materials from Caiyan Company.
Excuse me, what are the national standards for aramid 1313 yarn? Now what kind of methods and methods should our factory solve this matter? Please all friends to help us out of opinion!
