Ultra soft cotton/nylon blend
The fabric used in all of the Survive Arc clothing range is the ultra soft cotton/nylon blend. This is a premium fabric with many advantages over the synthetic / nomex modacrylics blends that other manufacturers use.
Whilst both types of fabrics are flame resistant, there are many reasons why the ultra soft cotton/ nylon blend are superior to the synthetic/nomex modacrylics blends. The ultra soft cotton/nylon blend is the lowest weight on the market that meets the 8 cal/cm2 threshold as a single layer. It can reach ATPV 24.3 cal/cm2 as a single layer. The synthetic/nomex modacrylics blends have poor characteristics such as poor insulation/heat retention, thermal shrinkage/body burns, skin irritation and poor breathability. These are outlined in the table below.
|APPLICATION||ULTRASOFT – COTTON/ NYLON BLENDS||SYNTHETIC / NOMEX MODACRYLICS BLENDS|
|Washability||200 washes||130 washes|
|Comfort||Excellent cotton next to skin||Not skin friendly|
|Resistance to electric arc flash||Excellent HTN fibre/cotton form a “break open barrier” and the HTN increases ATPV of the fabric||It works|
|Length of life cycle||Longer life cycle||Shorter life cycle|
|Weight v protection||200 gm2 = 8.3 cal/cm2 (single layer)||Heavier|
|Cool to wear||Double Synthetic blends, moisture wicked away||No|
|Heat Attenuation Factor||High – heat blocked out by the fabric||Poor|
|Insulator||Cotton – good in winter||Poor|
|Shrunk||Fabric is double pre-shrunk||n/a|
