Name two types of fabric testers and explain how they work.
Lilit [14]

Answer:

Merchandisers are the key persons in apparel business. They work as a bridge between buyer and seller. Merchandisers have to do various tasks from order execution to final dispatch. Developing Lab dip is one of the primary jobs for a merchandiser to start an order execution. They need to run for lab dip approval. Though this would be an easy task, sometimes big mistakes may occur. They have to do different fabric tests as buyer required. In this article I will briefly described different types of fabric test are completed by garment merchandisers.

It is necessary to validate the information that the mill or manufacturer gives you. This is normally done by having fabric tested by an accredited testing house (internationally recognized) either in the country of manufacturer or locally in your head office. Some companies have their own equipment and employ qualified fabric technicians to carry out the testing at their headquarters. When using an accredited testing house, it will not matter in which country the test is done, because the test has to be carried out to the agreed method, and no matter which country does the test, it will be done in exactly the same way. As the fabric construction is such an important part of the garment, when finalized, the fiber composition, weight, and yarn count should be added to your contract with the supplier.

The testing house will give you guidance on the result you should be achieving and the method that you should be using.
