BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a textile manufacturing field, in particular relates to a novel knitted fabric.

2. Description of the Related Art

Traditionally, sportswear is majorly fabricated by polyethylene terephthalate and nylon. Polyethylene terephthalate and nylon are petroleum products and most dependently obtained therefrom, but these products surely cause lots of pollutions to our environment. Pure natural cotton fiber is characterized with excellent moisture absorption, moisture retention and skin-friendly effects, but defects such as inferior elasticity, extensibility and strength, tendency to tension fracture, and less wear resistance are relatively existed, incapable of satisfying requirements of sport fabrics. Fabrics made of natural fiber or a viscose mixed with polyurethane fiber can have excellent wearing comfort, but they still have defects of less strength and bursting effect, inferior tension fracture, and tendency to wrinkling and deformation are existed. Fabrics made of nylon, polyethylene terephthalate and polyurethane fiber can have excellent strength, and difficulties of being burst and torn, but they still have less skin-friendly effect and cause serious pollutions to our environment. In America, Du-Pont Company disclosed a sorona polymer which contains a raw material of 37% obtained from nonpetroleum regenerative sources, capable of greatly reducing the human dependency of acquiring materials from limited petroleum sources and therefore obtaining reductions of a source consumption of 30% and a carbon dioxide gas discharge of 63% so that a perfect combination of functionalities of the related textile productions and purpose of environmental protections can be attained. Besides, sorona fiber is characterized with excellent stretchability and recoverability and properties of chloride resistance, ultraviolet resistance and anti-pollution and easy-to-clean effects, thus to be extensively applied on different kinds of clothing fabrics. However, fabrics made by adding sorona into the natural fiber or the viscose only can provide a slight flexibility, i.e., without high flexibility and high recoverability, and imperfect plastic effects. To overcome the above difficulties, technicians in this field shall study and develop how to apply an environmentally-protective fiber materials to allow a knitted fabric for preserving excellent functions of traditional chemical fiber fabrics and how to particularly provide advantages of skin-friendly effects, comforts, natures and environmental protections, which are also the production of the invention accordingly.
