Improving fabric durability

Improving fabric durability

(OP)
Folks,

I am developing a medical product, which requires a covering fabric that has to be very durable. The fabric also has very specific stretch and surface towelling effects.

Originally, I contacted a lot of fabric suppliers without success. I then found one company, which were willing to develop a fabric to our specific requirements. The fabrics have been fine except for poor durability, even though the company carried out 'snagging' and 'pilling tests' with good results.

On a 'nuts and bolts' level what should the fabric have to increase durability, by this I mean abrasion resistance.  For example, is it related closely to the tensile strength of the individual yarns?

Appreciate any comments or direction to any relevant websites. Thanks in advance.

I posted this a while back. As you can see there were no replies. I thought I might recycle it and try again.

Thanks in advance.

Does your fabric have nylon fibers in it? It generally provides strength, which equates to durability, and, if smooth, should be resistant to abrasion.

RE: Improving fabric durability

The main test for abrasion resistance is the "Taber" abrasion test.

Without knowing the overall requirements, it is very difficult to make a recommendation.

If you need good absorbency and abrasion resistance, you could try a viscose rayon and nylon blend. Twist level, yarn count, fibre diameter and fibre length will all have an impact, as will chemical treatment and fabric structure.
