Figure 20 shows the temperature dependence of creep deformation in nylon 6 under a tensile stress of 10 MPa. We would like to use it for Polyamide 6. The members of the family are distinguished from each other by a numbering system indicating the chemical composition of the polymer molecule. Most nylons, including 6 & 66, are semi-crystalline and possess good strength and durability for demanding applications. The spectrum C is for a nylon 6, 10 sample which had been melt-pressed and rapidly quenched to room temperature. When used in clothing, nylon is both lightweight and warm. HIGH POLYMER. However, nylon has many other uses. The growth in the use of polyamides in recent years comes from their increasing use in the automotive industry (for example, battery casings, brake hoses, oil sumps and fenders). Generally color of the nylon 6 is white but it could be colorful by adding different dyes in the solution bath before fiber production. Compared to Nylon 6/6 it can be molded about 80 degrees F (27 degrees C) lower with less mold shrinkage because it is slightly less crystalline. Nylon is a polyamide made from petroleum. Nylon melts and then burns rapidly if the flame remains on the melted fiber. This means it is a man made-chemical made up of two main atoms: carbon and fluorine. Its chemical properties does not allow it to be affected by solvents such as water , alcohol etc . Its properties are determined by the R and R' groups in the monomers.

Nylon is made from two monomers, each containing six carbon atoms, so the product is known as Nylon 6,6. In nylon 6,6, R' = 6C and R = 4C alkanes, but one also has to include the two carboxyl carbons in the diacid to get the number it donates to the chain. It also exhibits high abrasion resistance and self-lubricating properties. The majority of nylons tend to be semi-crystalline and are generally very tough materials with good thermal and chemical resistance. DuPont, founded by Éleuthère Irénée du Pont, first produced gunpowder and later cellulose-based paints. PA66 is still hygroscopic after molding, and the extent depends on the composition, wall thickness, and environmental conditions of the material. It is a very resilient fiber that is often used to make cords and ropes that need to support a lot of weight and withstand wet, hot or dirty conditions. Nylon 6,6 is very difficult to dye but once it is dyed it has a high colorfastness and is less susceptible to fading . Textile fiber consists of some characteristics. Physical Properties of Nylon 6 & Nylon 6,6 Fiber | Comparison/Different between Nylon 6 & Nylon 6,6 Fiber Nylon: Nylon was the first synthetic fibre to go into full-scale production and the only one to do so prior to World War II. With an increase in the nylon number, in the different types as mentioned above, there is a reduction in the values such as specific gravity, melting point, and moisture content. When you hear the word “nylon,” you probably think about a very thin and stretchable fabric for clothing.
