Anti-pilling merino wool fabric, garments comprising thereof, and method of fabrication thereof

An anti-pilling merino wool fabric with pilling resistance of at least 3.5 by JIS L1076 ICI method and less than 0.2% w/w of fiber loss upon home laundry for 15 cycles without the use of laundry net, the anti-pilling merino wool fabric being treated with a polycarbodiimide binder to crosslink polypeptides of the merino wool fabric comprising:

• dipping a merino wool fabric in a polycarbodiimide binder plus buffer solution followed by removing excess solution and drying, the polycarbodiimide binder being formed by:
• reacting isophorone diisocyanate and 1,6-hexamethylene diisocyanate with a first catalyst to form a first reaction product;
• reacting the first reaction product with a polyethylene glycol monomethyl ether water dispersing agent and a second catalyst to form the polycarbodiimide binder and mixing the polycarbodiimide binder with a buffer solution to form the polycarbodiimide binder formulation wherein the binder plus buffer solution comprises approximately 8 to 30% w/w polymer binder in water and approximately 70 to 92% w/w buffer in water, and wherein the buffer is selected from phosphate or borate.
