The value of wool is as long-lasting as the fibre itself. Inherently flame retardant, resistant to dirt and crushing, it is naturally superior to synthetics. See for yourself!

The Weaknesses of Nylon (polyamide) are:

• Inferior handle (feel) compared to wool
• High affinity for soiling
• Poor resistance to burning (it melts)
• fibre surface damage through use (leads to increased soiling, reduced oil release)
• Damaged by acids (e.g., formic acid).
• Susceptible to degradation by sunlight

The Drawbacks of Polypropylene are:

• Organic solvents and oxidizing agents cause fibre to swell and lose strength
• Lower abrasion resistance than polyamide
• Poor resilience
• Low melting point
• Susceptibility to soiling
• Very poor dye-ability
• Susceptible to oil-based stains

The Disadvantages of Polyester are:

• Less resilient than wool or polyamide
• Range of lustres limited
• Sensitive to cigarette burns
• Lower soil resistance/inferior soil release than wool
• Poorer abrasion resistance than polyamide
• Degraded by ammonia

The Weaknesses of Acrylic are:

• Lower abrasion resilience than polyamide
• High soiling propensity
• Poorer resistance to burning (although flame retardant variants are available), but releases toxic gases (contains cyanide group).
• Fuzzing and pilling in coarse gauge loop pile
• Limited resistance to some organic solvents and strong alkali
