The present invention belongs to the technical field of helmets, and particularly relates to a sawdust helmet and a manufacturing method.
The existing helmet is generally composed of a helmet body, an inner buffer layer and a wearing device, wherein the helmet body is generally made of hard materials. The buffer layer (body) is arranged on the inner surface of the helmet body for absorbing the impact force generated, and the wearing device is used for fixing the helmet body to the head of a human body.
The buffer layer inside the helmet on the market is basically made of plastic materials, such as EPS, EPP, etc., and there are certain shortcomings in the use process:
The buffer layer has single material and single color. For beautification, the surface is often painted with color ink, film, etc., which increases the processing complexity of the buffer layer and also increases the production cost to a certain extent.
Moreover, the texture of the buffer layer is not particularly good. The texture is single. According to different used materials, the buffer layer is either hard or soft. Based on this, in order to increase the beauty of the buffer layer of the helmet and improve a good feeling of contact between the buffer layer of the helmet and the head (such as softness, comfort, etc.), providing a helmet including a sawdust buffer body has good market prospects.
