How do you distinguish nylon 6 and nylon 66

Regarding the difference between the two, there are mainly six points. Here, nylon is temporarily called PA. Easy to remember. Now let me introduce you.


1. Melting point and elasticity. The melting point of nylon 6 is 220C and the melting point of nylon 66 is 260C. However, this is not a difference for the temperature conditions of the carpet. The lower melting point makes nylon 6 have better resilience, fatigue resistance and thermal stability than nylon 66.


2. Properties, PA6 has good toughness, cheapness, and low melting point. Generally, there are more products made with glass fiber, mainly used in electronics, electrical appliances, auto parts, sports equipment, DuPont PA66 has good strength, wear resistance, high melting point, and general There are many products made with glass fiber, mainly used in electronics, electrical appliances, and accessories.


3. Structure, nylon 6 is polycaprolactam, and nylon 66 is polyhexamethylene adipate. Nylon 66 is 12% harder than nylon 6, and theoretically, the higher the hardness of nylon, the more brittle the fiber, and the easier it is to break. But this slight difference in carpet usage cannot be distinguished.


4. Cleaning and antifouling properties. 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 stain resistance.


5. Color fastness. Color fastness is not a characteristic of nylon. It is the dye in nylon rather than the fading of nylon itself under light.


6. Abrasion resistance and dust resistance. Clemson University in the United States used BASF Zeftron500 nylon 6 carpet and DuPont AntronXL nylon 66 carpet for 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 Zeftron500 nylon is slightly better than DuPont Antron XL in terms of color retention and pile wear resistance. There is no difference in the dust resistance of the two yarns.


People are no strangers to nylon, nylon products abound in daily life, but few people know its history. Nylon is the first synthetic fiber developed in the world.
