Embodiment 1
[0032] A method for producing bamboo cotton from bamboo is characterized in that: it follows the steps:
[0033] (1) Processing of bamboo chips
[0034] (1) The felled bamboo is debranched, tipped, and knotted, and the bamboo tube is cut into 2-5 cm wide bamboo slices.
[0035] (2) Put the bamboo slices into a roller compactor to flatten and disperse the bamboo fibers so that the bamboo fibers are preliminarily dispersed.
[0036] The rolling machine adopts multi-roller groups with variable gaps for continuous rolling, and the gaps between the roller groups gradually become smaller.
[0037] (2) Softening and degumming of bamboo chips
[0038] Put the bamboo raw material obtained in step (2) in (1) into an ultrasonic container, add the formula sodium hydroxide, urea and dimethyl sulfoxide aqueous solution, turn on the ultrasonic reaction for two hours, then remove and drain the water.
[0039] The proportion by weight is: 1% sodium hydroxide, 1% urea,
[0040] 0.5% dimethy...
Embodiment 2
[0060] A method for producing bamboo cotton from bamboo, (2) softening and degumming of bamboo chips
[0061] Put the bamboo raw material obtained in step (2) in (1) into an ultrasonic container, add the formula sodium hydroxide, urea and dimethyl sulfoxide aqueous solution, turn on the ultrasonic reaction for two hours, then remove and drain the water.
[0062] The proportion by weight is: sodium hydroxide 2%, urea 2%,
[0063] Dimethyl sulfoxide 1.5%, the balance is water.
[0064] The weight percent of formula is: simethicone 60%, gasoline 40%;
[0065] The weight ratio of the mixed liquid and the thick silk fiber is 3:100.
[0066] (7) Bleaching
[0067] Put step (6) gained raw material into the plastic container that fills 5000ppm chlorine dioxide and bleach, bleach for 8-10 hours, pull out and dehydrate and dry;
Embodiment 3
[0069] A method for producing bamboo cotton from bamboo, (2) softening and degumming of bamboo chips
[0070] Put the bamboo raw material obtained in step (2) in (1) into an ultrasonic container, add the formula sodium hydroxide, urea and dimethyl sulfoxide aqueous solution, turn on the ultrasonic reaction for two hours, then remove and drain the water.
[0071] The proportion by weight is: 1.5% sodium hydroxide and 1.5% urea.
[0072] 1% dimethyl sulfoxide, the balance water.
[0073] (5) Wetting modification improves toughness and strength
[0074] Dry the coarse silk fiber obtained in step 4, and then use a sprayer to spray the mixture of simethicone oil and gasoline. Stop when the surface of the thick silk fiber is wet.
[0075] The weight percentage of the formula is: 50% of simethicone oil, 50% of gasoline;
[0076] The weight ratio of the mixture liquid and the thick silk fiber is 2:100.
[0077] (7) Bleaching
[0078] Put the raw material obtained in step (6) int...
