Problems solved by technology

However, polyacrylonitrile also has many disadvantages: poor hydrophilicity, easy to charge static electricity in dry weather and poor human affinity
However, the production of viscose fiber is easy to cause environmental pollution, and the cost of carboxymethyl chitosan is high, which restricts its development.

Abstract

The invention discloses a polyacrylonitrile-sodium alginate composite fibre. The said fibre is formed from sodium alginate and polyacrylonitrile, the sodium alginate content is 1-20% and the polyacrylonitrile content is 80-99%. Said invention also provides the concrete steps of its production method, and the invented composite fibre can raise human body substantivity of polyacrylonitrile fibre, can make polyacrylonitrile fibre have the special effect of resisting bacteria and relieving itching, raise its dyeability and reduce its pilling property.

Description

technical field [0001] The invention relates to a composite material and a manufacturing method thereof, in particular to a polyacrylonitrile-sodium alginate composite fiber and a manufacturing method thereof. Background technique [0002] Polyacrylonitrile fiber, commonly known as acrylic fiber, is a synthetic fiber with excellent warmth retention, excellent dyeability, and no moth and mildew properties. After dyeing, it can obtain brighter colors than wool. Polyacrylonitrile is widely used. It is used to make wool-like products, so polyacrylonitrile is also called artificial wool. However, polyacrylonitrile also has many disadvantages: poor hydrophilicity, resulting in easy static charge in dry weather and poor human affinity. Sodium alginate is used as a printing aid, which makes the printed pattern clear, bright, high color yield and good hand feeling. By adding sodium alginate, the hairiness of the fiber can also be reduced. [0003] In order to improve the performan...
