Embodiment 1

[0026] Take a certain quality of fresh red rose petals, add deionized water equivalent to 1 times the dry weight of the petals, soak for 10 min, pour it into a pulverizer, crush the petals at a speed of 200 rpm for 30 min, and obtain Slurry dispersion. Then the dispersion is poured into a high-pressure homogenizer, and homogenized 20 times at 100 bar to obtain a nano-sized flower fiber dispersion ( figure 2 ). Mix the flower fiber dispersion and sodium alginate in water; wherein, the quality of sodium alginate accounts for 5% of the absolute dry weight of the flower fiber, and the concentration of the spinning solution after preparation is 3%. After vacuum degassing, the spinning solution is injected into a coagulation bath (5% calcium chloride solution), and the obtained flower fiber filaments are collected by a reel, and the red rose fiber can be obtained after air drying. The process of this embodiment is as follows figure 1 as shown, image 3 For the obtained red ros...

Embodiment 2

[0029] Take a certain quality of fresh lily petals, pour them into a pulverizer, and crush them for 1 min at a speed of 2000 rpm to obtain a slurry-like dispersion. Then pour the dispersion into a high-pressure homogenizer, and homogenize it five times at 900 bar to obtain a nano-sized flower fiber dispersion. The flower fiber dispersion and natural guar gum are compounded in water; wherein, the quality of guar gum accounts for 50% of the absolute dry weight of flower fiber, and the concentration of the spinning solution after preparation is 3%. After ultrasonic degassing, the spinning solution was injected into a coagulation bath (1wt% borax solution), and the obtained flower fiber filaments were collected by a reel, and lily flower fibers could be obtained after air-drying. The flow of this embodiment is as follows Figure 4 as shown, Figure 5 Be the lily fiber that this embodiment obtains.

Embodiment 3

[0032] Take a certain quality of fresh carnation petals, add deionized water equivalent to 10 times the dry weight of the petals, soak for 16 minutes, pour it into a pulverizer, and crush it at a speed of 700 rpm for 5 minutes to obtain a pulp shaped dispersion. Then pour the dispersion into a high-pressure homogenizer, and homogenize it for 7 times at 300 bar to obtain a nano-sized flower fiber dispersion. The flower fiber dispersion and chitosan were compounded in 2% acetic acid aqueous solution; wherein, the quality of chitosan accounted for 80% of the absolute dry weight of flower fiber, and the concentration of the spinning solution after preparation was 5%. After vacuum degassing, the spinning solution is injected into a coagulation bath (5% sodium hydroxide + 0.5% sodium sulfate solution, or pure water), and the obtained flower fiber filaments are collected by a reel, and the carnation flower fiber can be obtained after air drying.

Abstract

The invention provides a flower fiber filament for weaving, which is prepared by the following method: (1) take an appropriate amount of flower petals, and preliminarily crush them to obtain a slurry-like dispersion; then perform high-pressure homogenization treatment to obtain a flower fiber dispersion. (2) After adding the fresh flower fiber dispersion liquid to the spinning solvent, add functional additives to make it compound with the fresh flower fiber dispersion liquid to obtain the fiber dispersion liquid for spinning. (3) The fiber dispersion used for spinning is degassed, injected into a coagulation bath by a spinning machine, collected by a reel and dried to obtain flower fiber filaments. The present invention realizes the full-component wet spinning of petals for the first time, the preparation process is simple, the conditions are mild, and pollution-free, which reduces the cost of fiber filament preparation; in addition, the final product maintains the natural primary crystal form of cellulose, and also has Natural aromatic scent and color in petals. In summary, the fresh flower fiber filament will have broad market application prospects and huge economic value.

Description

technical field [0001] The invention belongs to the field of materials, and relates to a method for preparing textile fibers, in particular to a method for directly preparing fiber filaments from flower fibers. Background technique [0002] "Try the man with the curtain, but the begonia is still the same. Do you know, do you know, it should be green, fat, red and thin." From ancient times to the present, flowers have always been the object of praise by literati and poets; all because flowers are indeed refreshing and joyful. . In addition to having ornamental value, because flowers are rich in carbohydrates, proteins, amino acids, mineral elements, etc., with the development of science and technology, flowers have more and more uses. At present, research on the application of flowers is mainly concentrated in the fields of decorations, cosmetics, food, and medicine (AVRDC-The World Vegetable Center, 2012, Publication No. 12-758); and these uses are usually through direct co...
