The invention provides a formaldehyde-free fiber material and a formation method thereof. The method comprises the following steps: the fiber material is ground into filaments to enable the filaments of the fiber raw material to be loose and basically keep sticky, the filaments and an adhesive are arranged in an alternative manner to form layers, an upper surface layer and a lower surface layer are layers formed by the filaments of the fiber material, and finally hot pressing and cold pressing are sequentially performed, wherein the adhesive comprises LDPE and HDPE. The invention further provides a fiber decorative material and a manufacturing method thereof. According to the fiber decorative material manufacturing method, salix psammophila and a branch material with small diameter are utilized to manufacture the fiber decorative material, and the manufactured fiber decorative material has the advantages of strong nail-holding power, high non-deformability, high resistance to bending and high resistance to tension so as to change salix psammophila and the branch material into valuable things, and the fiber decorative material has great commercial value; in addition, the formaldehyde-free fiber material formation method and the fiber decorative material manufacturing method are simple and have no special requirements for equipment, and the formaldehyde-free fiber material and the fiber decorative material are suitable for large-scale industrial production.
