[0015] Example one:
[0016] The manufacturing method of the bamboo fiber needled felt of the present invention is realized by the following steps:
[0017] 1) Material preparation: prepare 30wt% bamboo fiber and 70wt% polyester fiber, the fineness of bamboo fiber and polyester fiber is 1-4D, and the length is 25-76mm;
[0018] 2) Opening and mixing: The raw bamboo fiber and polyester fiber are fed into the opening machine to maximize the fluffy state and mix them evenly;
[0019] 3) Carding: Feed the opened and mixed bamboo raw fiber and ester poly fiber to the carding machine for carding to form a fiber web. The feed line speed is 0.5m / min and the feed fiber amount is 2kg / m. 2 , The main cylinder frequency of the carding machine is 400r / min. During this process, the indoor temperature is controlled at 15°C and the relative humidity is controlled at 60%;
[0020] 3) Laying: Repeatedly overlap the fiber web obtained by carding to a weight of 200-450g / m 2 ;
