Flame-retardant 100% staple spun polyester for children's nightwear
Or search via thread type
Coats Astra FR is a spun polyester thread with passive flame-retardant properties. It is produced to conform to the legislation BS EN 14878:2007 (Nightwear Safety Regulations), on flammability in children's nightwear, as adopted by many leading retailers.
Coats Astra FR has been proven to provide satisfactory performance even under difficult flammability conditions. Proper seam construction is an integral part of the testing.
Sewing thread is not the only element that impacts on total garment flammability, and the use of a flame-retardant thread will not help if the fabric itself is flammable. Nevertheless, it has been shown that the use of a standard thread without flame-retardant characteristics can cause the seams of a garment to fail standard flammability tests even when the fabric is flame-retardant.

Since conditions and applications vary considerably in the use of the thread, Coats and its distributors can make no guarantee of results. These recommendations are given in good faith but without warranty or liability on the company or its employees. The thread user should assure herself or himself by preliminarily testing that the thread is suitable for the end use intended. Technical information listed above is based on current averages and should be taken only as indicative.

It is sometimes the practice in many garment manufacturers to add additional lubricants to the thread or fabric prior to or during sewing. This practice can promote flammability in the finished garment and should be prohibited. Coats applies a carefully formulated lubricant in a controlled amount to the thread, and this will permit the thread to be sewn under normal machine conditions and speeds. Coats cannot accept any responsibility for the flammability performance of the product if any additional lubricants and finishes are applied during processing.
Coats Astra FR has been developed to meet the requirements of U.S. Legislation CFR1615 and BS EN 14878:2007 (Nightwear Safety Regulations) test for flame retardancy in finished apparel. Flame retardancy in textile products depends on a complex interaction of variables, and thread and seam performances are highly dependent on other factors, including the type of fabric which is used. It is the responsibility of the thread users to satisfy themselves that the thread meets their particular fire retardant requirements when sewn into a finished product. Whilst Coats accepts that it is able to confirm that the thread supplied will meet the specification as set out in U.S. Legislation CFR1615 and BS EN 14878:2007 (Nightwear Safety Regulations) (when tested using Coats' method for seam evaluation). Coats cannot accept any liability arising from the user's own negligence.
