Description
Technical field
The present invention relates to a kind of manufacture method of functional fibre, especially a kind of manufacture method of white acrylic fibers conductive fiber.
Background technology
Acrylic fibers are polyacrylonitrile fibre trade names in China, have higher elasticity, intensity, heat resistance, light resistance and anti-corrosive properties, are widely used in textile industry.Due to its lovely luster, light weight and softness, outward appearance and feel are all similar to wool, therefore there is the title of " synthetic wool ".But because it is hydrophobic fibre, hygroscopicity is poor, easily play static, and its snugness of fit is far away not as good as wool.
The large molecule of polyacrylonitrile (PAN) in acrylic fibers contains a large amount of hydrophobic groups, makes acrylic fibers have the hygroscopicity of strong-hydrophobicity and extreme difference, and electrostatic phenomenon very easily occurs.In process, can be wound around or stop up parts with the fiber of static; While weaving, be prone to Warp opening unclear, the fabric folded phenomenon such as uneven, what impact was produced carries out smoothly.In use, build-up of static charges easily causes that dust adheres to acrylic fibers textiles, and clothes tangle limbs, produces and adheres to sense of discomfort; And can cause the physiological change such as pH value of blood rising; These have all greatly reduced the wearability of acrylic fibers textiless.In addition, the high potential being produced by static may produce electric shock to human body, also may cause electronic component to damage by breakdown potential sub-element; The electromagnetic radiation meeting that static discharge produces is to various electronic equipments, and information system causes electromagnetic interference.In order to eliminate the static of acrylic fiber and goods thereof, promote that acrylic fiber production process develops rapidly, meet the growing demand for high quality fiber and fabric of people, people start to seek acrylic fibers to carry out the method for modification, strengthen its hygroscopicity and antistatic behaviour, improve its defect in production and application, make it as natural wool, there is good comfortableness and hygroscopicity and can stop electrostatic phenomenon as far as possible, strengthen its development.
The volume resistivity of common acrylic fibers under standard state is 1013 Ω cm, it is generally acknowledged, the volume resistivity of fiber is less than 1010 Ω cm can reach antistatic effect, the volume resistivity of acrylic fibers can be down to below 108 Ω cm by modification, and this acrylic fiber is called as conductive acrylic fibre.Resistant fiber electrostatic technique key is to make fiber to possess lower specific insulation in keeping its original premium properties.
The common method of preparing conductive acrylic fibre has: (1) introduces hydrophilic compounds in copolymer, improves the hygroscopicity of product, thereby makes acrylic fibers have electric conductivity; (2) in acrylic fibers, add the blend of a small amount of carbon black class conductive materials to make durability conductive acrylic fibre; (3) process fiber surface with copper salt solution, make conventional acrylic fibers surface attachment metal coating, make the conductive acrylic fibre that not affected by ambient humidity.
The specific insulation of conductive acrylic fibre fibre prepared by above-mentioned preparation method be generally all greater than 1010 Ω cm and color deep, prepare specific insulation more difficult at the acrylic fibers conductive fiber of 105 ~ 109 Ω cm.
