The invention discloses an uncolored bamboo
fiber with high
antibacterial activity. The beating degree of the
fiber is 16-25 0SR, the fracture length ranges from 4 km to 6 km, the folding number ranges from 65 to 80, the whiteness is 22-25% ISO, the value of
potassium permanganate ranges from 80 to 100, and the antibacterial rate is greater than or equal to 90%. A
processing method of the uncolored bamboo
fiber includes the steps that 1, materials are prepared, wherein bamboo
plant raw materials are processed to be bamboo chips in a wet method; 2, cooking is carried out, wherein the bamboo chips are added into a
potassium hydroxide solution and are heated to be at the temperature of 110-125 DEG C through steam, then the temperature is kept for 50-60 minutes, and a bamboo fiber material is obtained; 3, antibacterial treatment is carried out, wherein high molecular
chitosan is added after the cooked bamboo fiber material is grinded into thick liquid. The uncolored bamboo fiber has the large fiber length, high flexibility and good water absorbing and water-retaining properties, and is soft in texture, fluffy and high in
antibacterial property, the natural color of the bamboo fiber is kept, and the quality of down-
stream products is improved remarkably. The
processing method has the characteristics that operation is easy, production is convenient, the cost is low, and
environmental protection is achieved.
