preparation example Construction

[0020] According to the present invention, a kind of preparation method of whole bamboo fiber is provided, comprising:

[0021] a) soaking process, soaking the pretreated bamboo chips in a neutral aqueous solution containing 0.01% to 0.05% (w / w) penetrating agent for 8 to 11 hours;

[0022] b) Cooking process, the soaked bamboo chips are boiled for 3.0~3.5 hours under normal pressure in the cooking liquid, the bath ratio during cooking is 1:15~60, sodium hydroxide in cooking: 3~125g / l, sodium carbonate 3~135g / l, sodium sulfite 0.4~50g / l, sodium silicate 0.2~50g / l;

[0023] c) fiber opening process, the bamboo fiber after cooking is carried out high-temperature heat preservation under the effect of ultrasonic wave, then release pressure quickly, and cycle this process for many times;

[0024] d) pickling, bleaching, cleaning, dehydrating and drying the bamboo fibers obtained after fiber opening to obtain bamboo fibers.

[0025] According to the present invention, when the fib...

Abstract

The invention discloses a preparation method of all bamboo fibers. The preparation method comprises the following steps: (a) a soaking procedure, namely, soaking preprocessed bamboo pieces in a neutral aqueous solution with 0.01%-0.05% (w / w) of penetrant for 8-11 hours; (b) a cooking procedure, namely, cooking the soaked bamboo pieces in cooking liquor at normal pressure for 3.0-3.5 hours, wherein during cooking, a bath ratio is equal to 1:(15-60), and the cooking liquor per liter contains 3-125g of sodium hydroxide, 3-135g of sodium carbonate, 0.4-50g of sodium sulfite and 0.2-50g of sodium silicate; (2) a splitting procedure, namely, performing high-temperature heat preservation on cooked bamboo fibers under the action of ultrasonic waves, quickly releasing pressure, and circulating the process for multiple times; and (d) picking, bleaching, cleaning, dehydrating and drying the split bamboo fibers to obtain the all bamboo fibers. During the splitting process, the fibers can be fully separated to obtain the fine and soft bamboo fibers through the combination of ultrasonic waves and high-temperature heat preservation as well as quick pressure release.

Description

technical field [0001] The invention relates to the textile field, in particular to a preparation method of whole bamboo fibers. Background technique [0002] Bamboo fiber is a kind of cellulose fiber extracted from naturally growing bamboo, and it is the fifth largest natural fiber after cotton, hemp, wool and silk. Bamboo fiber has good air permeability, instant water absorption, strong wear resistance and good dyeing properties, and at the same time has natural antibacterial, antibacterial, anti-mite, deodorant and anti-ultraviolet functions. Bamboo fiber is a kind of natural and environment-friendly green fiber in the true sense. The textiles made of it completely replicate the inherent characteristics of bamboo fiber. It is known as "breathing ecological home textile" and "fiber queen". The development of bamboo fiber has good economic and social benefits. [0003] The patented technology of multiple bamboo fibers has been disclosed in the prior art, CN1107852C disclo...
