Outdoor shade sail fabric material

  Outdoor shade sail fabrics generally have two categories of acrylic fiber and polyester fiber fabric

  Acrylic generally refers to polyacrylonitrile fibers, synthetic fibers made of acrylonitrile copolymers with a polyacrylonitrile or acrylonitrile composition greater than 85% (mass percentage). Common second monomers are non-ionic monomers, such as methyl acrylate, methyl methacrylate, etc. The third monomers are ionic monomers such as sodium propylene sulfonate and 2-methylene-1,4- Succinic acid and so on.

  The performance of polyacrylonitrile fiber is very similar to wool, and its elasticity is good. The resilience rate is still 65% at 20% elongation. It is fluffy, curled and soft, and its thermal retention is 15% higher than wool. It is called synthetic wool. The strength is 22.1 ～ 48.5cN / dtex, which is 1 ～ 2.5 times higher than wool. The light resistance is of high quality. It can only be used for curtains, curtains, tarpaulins, cannons, etc. when exposed to the open air for one year, and the strength only drops by 20%. Resistant to acids, oxidants and common organic solvents, but poorly resistant to alkalis. Fiber softening temperature is 190 ～ 230 ℃.

  Acrylic fiber is known as artificial wool. It has soft, bulky, easy to dye, bright color, light resistance, antibacterial, and can be purely spun or blended with natural fibers according to the requirements of different advantages such as being not afraid of insects. Its textiles are widely used in clothing, decoration, industry field. Polyacrylonitrile fiber can be blended with wool into wool, or woven into blankets, carpets, etc., and can also be blended with cotton, man-made fibers, and other synthetic fibers to weave a variety of clothing and indoor products. The bulk of polyacrylonitrile fiber processing can be pure spinning or blended with viscose fiber.
