Embodiment Construction

[0026] The following figures and preferred embodiments of the present invention further illustrate the technical means adopted by the present invention to achieve the intended purpose of the invention.

[0027] See figure 1 As shown, the composite fiber 10 of the present invention is composed of a core material 11 and a shell 12, the core material 11 is in the shape of a circular elongated strip, the shell 12 is formed around the core material 11, and the shell 12 The melting temperature is lower than the melting temperature of the core material 11, the strength of the outer shell 12 is higher than the strength of the core 11, and the outer shell 12 of each composite fiber 10 is closely connected with the outer shell 12 of an adjacent composite fiber 10. In addition, the composite fiber 10 is roughly in the shape of a round strip.

[0028] In a preferred embodiment, the core material 11 is made of polypropylene copolymer or polypropylene homopolymer, and the outer shell 12 is made ...

Abstract

The invention discloses a composite fiber, a composite board and a method for preparing the composite board. The composite fiber is composed of a core material and a shell, wherein the shell is encircled and formed around the core material; the melting temperature of the shell is lower than that of the core material; and the strength of the shell is higher than that of the core material. Accordingto the composite fiber, the composite board with high the characteristics such as impact strength, easy molding, low extension, light weight and high heat resistance simultaneously can be prepared, so that the requirement of sport protection is met.

Description

Technical field [0001] The invention relates to a composite fiber, a composite board and a method for preparing the composite board. Background technique [0002] As sports injuries often occur in sports training or sports competitions, the prior art provides a variety of sports protective gear, such as knee pads, ankle pads, elbow pads, etc., for people to choose from. Among them, the prior art sports protective gear is made by weaving and shaping a single component fiber [such as polypropylene fiber]. However, since the prior art protective articles are made of single-component fibers, their strength is limited, so they cannot provide good protection. Summary of the invention [0003] In view of the above shortcomings of the prior art, an object of the present invention is to provide a composite fiber, which can produce a composite board with good impact resistance, so as to meet the requirements of sports protection. [0004] In order to achieve the aforementioned purpose of th...
