Nylon fabric is famous for its excellent wear resistance. It is not only the best choice for mountaineering clothing material, but also often blended or interwoven with other fibers to improve the strength and fastness of the fabric.
The hygroscopicity of nylon fabric is a better variety in synthetic fiber fabric, so it is more comfortable to wear than polyester clothing made of nylon.
Nylon fabric commonly known as nylon, below, we will introduce what nylon is.
Nylon is the United States outstanding scientist Carothers (Carothers) and his leadership of a scientific research group developed, is the world’s first synthetic fiber.
The appearance of nylon makes textiles take on a new look. Its synthesis is a major breakthrough in synthetic fiber industry and an important milestone in polymer chemistry.
Polyamide fiber commonly known as Nylon, English name Polyamide(PA), density 1.15g/cm3, is the molecular backbone of the thermoplastic resin containing repeated amide group – [NHCO] – general term, including aliphatic PA, adipo-aromatic PA and aromatic PA.
Aliphatic PA has many varieties, large yield and wide application, and its name is determined by the specific number of carbon atoms of the synthetic monomer.
By the famous American chemist Carothers and his scientific research team invented.
Nylon is a term for polyamide fiber (polyamide), which can be made of long or staple fiber.
Nylon is the trade name of polyamide fiber, also called nylon (Nylon).
Polyamide(PA) is an aliphatic polyamide linked by an amide bond (NHCO).
Two, nylon products 1, enhance PA in PA add 30% glass fiber, PA mechanical properties, dimensional stability, heat resistance, aging resistance has been significantly improved, fatigue resistance 2, nylon strength is not enhanced 2.5 times.
The molding process of glass fiber reinforced PA is roughly the same as that of unreinforced PA, but because the flow is worse than that before strengthening, so the injection pressure and injection speed should be increased appropriately, and the barrel temperature should be increased by 10-40¡æ.
Because the glass fiber will be oriented along the flow direction in the injection process, causing mechanical properties and shrinkage in the orientation direction, leading to product deformation and warping, therefore, mold design, the location and shape of the gate to be reasonable, the process can increase the temperature of the mold, the product is taken out into hot water to cool it slowly.
In addition, the greater the proportion of glass fiber added, the greater the wear of the plastic components of the injection molding machine, it is best to use bimetallic screw, cylinder.
