UK import company requests: fabric

We are currently investigating the best fabrics for the items of clothing we are manufacturing. We are looking for a polyester/spandex blend and also a nylon/spandex. We will be producing multiple items with both the nylon and polyester. We are still deciding what percentage blend we require and also what GSM we require for each product. We are looking to get samples/swatches shipped to us as soon as possible. Can you firstly inform me what polyester/spandex and nylon/spandex blends you have available, plus the GSM, and then I will decide which samples I require. We will be producing sports clothing, and therefore the polyester and nylon blends have to be appropriate to fit this requirement.

Please find attached a document detailing many of the requirements for our planned products.

After extensive research, we have compiled these specifications and would appreciate your comments and expertise on these selections. For example, we would expect to use a different type of polyester and different knit for a hoodie and a pair of shorts. The shorts may be single knit whereas the hoodie is double knit or 3D.

Please make appropriate suggestions for the materials required for each item and the specifications you can provide.
