Washability and antifouling
Affecting these two properties is the cross-sectional shape of the fiber and the antifouling treatment of the subsequent channels. The strength and hardness of the fiber itself have little effect on cleaning and antifouling properties.
Melting point and elasticity
Nylon 6 has a melting point of 220 ° C and nylon 66 has a melting point of 260 ° C. But this is not a difference in terms of the temperature conditions of the carpet. The lower melting point allows nylon 6 to have better resilience, fatigue resistance and thermal stability than nylon 66.
Color fastness is not a property of nylon. It is the dye in nylon rather than the nylon itself that fades under illumination.
Wear resistance and dust resistance
The University of Clemson in the United States conducted a two-and-a-half-year experiment with Zeftron 500 nylon 6 carpet and Antron XL nylon 66 carpet at the Tampa International Airport. The carpet was in a very high flow rate and the results showed that BASF Zeftron 500 nylon is slightly better than Antron XL in terms of color retention and pile wear resistance. There is no difference in the dust resistance of the two yarns.
