Fabric knowledge: Polyester and Polyamide

  • 1. Features:

     

    High strength, good impact resistance, heat resistance, corrosion resistance, moth resistance, acid and alkali resistance, good light resistance (second only to acrylic), 1000 hours of exposure, 60-70% strength, poor hygroscopicity, dyeing Difficult, the fabric is easy to wash and dry, and has good shape retention. Has a "wash and wear" feature.

     

    2. Purpose:

     

    Filament use: often used as low elastic yarn to make various textiles.

    Short fiber use: blended weave with cotton, wool, linen, etc. industrial: tire cord, fishing nets, ropes, filter cloth, insulation materials, etc. It is currently the largest amount of chemical fiber.

     

    3. Dyeing:

     

    Generally, disperse dyes are used for dyeing, with high temperature and high pressure.

     

     

     

    --Polyamide (Nylon): strong and wear-resistant

     

    the advantage of Nylon

     

    1. Features:

     

    The biggest advantage of nylon is that it is strong and wear-resistant, which is the best one. Low density, light fabric, good elasticity, fatigue resistance, good chemical stability, alkali resistance but not acid resistance.

     

    The biggest disadvantage is that the sun resistance is not good, the fabric will turn yellow after a long time, the strength will decrease, and the moisture absorption is not good, but it is better than acrylic and polyester.

     

    2. Purpose:

     

    Filament, mostly used in knitting and silk industry; staple fiber, mostly blended with wool or wool-type chemical fiber, Industry: cords and fishing nets, can also be used as carpets, ropes, conveyor belts, screens, etc.

     

    3. Dyeing:

     

    Acid dyes are generally used, which can be dyed at room temperature and pressure.
