Cleanability and antifouling
What affects these two properties is the cross-sectional shape of the fiber and the antifouling treatment in the subsequent process. The strength and hardness of the fiber itself have little effect on cleaning and antifouling properties.
Melting point and elasticity
The melting point of nylon 6 is 220°C and the melting point of nylon 66 is 260°C. However, this is not a difference in terms of the temperature conditions of the carpet. The lower melting point makes nylon 6 have better resilience, fatigue resistance and thermal stability than nylon 66.
Color fastness
Color fastness is not a characteristic of nylon, it is the dye in nylon, not the nylon itself, which fades under light.
Wear resistance and dust resistance
Clemson University in the United States used Zeftron500 nylon 6 carpet and Antron XL nylon 66 carpet to conduct a two-and-a-half-year experiment at Tampa International Airport. The carpet is in a state of extremely high traffic. The results show that BASF's Zeftron 500 nylon is slightly better than Antron XL in terms of color retention and pile abrasion resistance. There is no difference in the dust resistance of the two yarns.
