Assignment 2 -Group 1
Example: Natural Nylon cord for lariatsThe item we chose is nylon cord that is used by ropers for lariats. This particular piece is naturally white, yet yellow and violet are also common colors. The cord is made of Nylon 6 yarn produced by Allied Signal Fibers, now known as Honeywell Fibers.
Nylon is a man made fiber which comes in two forms, Nylon 6 and Nylon 66. Nylon 6 yarn is made of caprolactum,which has six carbons in its structure, hints the name Nylon 6. Nylon 6 is most common in Europe but is becoming more popular in the U.S. This cord has a 1260 denier rate and is twisted in a 2/3 fashion. This means it is composed of two ply yarns twisted in the "S" direction; then three of these cabled yarns are twisted in the "Z" direction. Their twists are parallel for best strength. The breaking strength of Nylon 6 is extremly high at 4 to 7 g/d. This high strength makes it ideal for lariats.
Nylon 6 naturally has a high luster, unless delustered. Nylon can stretch, or elongate, very easily but also recovers well. Another good quality of nylon is that it is chemically stable. This is an advantage to nylon fabrics in that you can dry clean them and they will not be harmed. Finally, this fiber is very resistant to abrasion. This is a major plus given the fact that lariats are drug on the ground so much.
Comments
Group 5: Very well written, and informative. Leaves no doubt that I could manufacture nylon cord in my basement (well, maybe not).
Group 8: Group 1 does a very good job of describing the properties of a nylon fiber. They give a very detailed decription of how the nylon fibers are manufactured into fibers.
