Description

VISCOSE LARGE BIOLOGICAL FIBER CONTAINING ACTIVE INGREDIENTS OF ALBIZIA JULIBRISSIN, OLIVE, PEPPERMINT AND LAVENDER AND METHOD FOR PREPARING SAME TECHNICAL FIELD

This application relates to fiber preparation, and more particularly to a viscose

large biological fiber containing active ingredients of Albizia julibrissin, olive,

peppermint and lavender and a method for preparing the same.

BACKGROUND

Albizia julibrissin, also known as velvet flower tree and Lantana camara, is a

deciduous tree and blooms in summer. It has head-like inflorescence gamopetalous

corolla. The flower has multiple stamens and is light red. The pod is of a strip shape,

and is flat and indehiscent. The tree height is 4-15 meters, and the crown is unfolded.

Branchlets are angular, tender branches, inflorescences and leaf rachis are tomentose

or pubescent. The stipules are linear-lanceolate; the heads are arranged in panicles at

the top of the branches; the flowers are pink; the calyx is tubular. Florescence is from

June, and the fruiting is from August to October.

Olive is an arbor of the olive family, native to southern China, but also cultivated

in northern to central Vietnam, Japan (Nagasaki, Okinawa) and the Malay Peninsula.

The olive is widely used, the olive wood is a good building material, the olive flesh

can be used for food or medicine, and the olives nucleus can be used for carving and

oil-pressing. Olive oil is a light-yellow clear liquid extracted from olive fruits, called "

gold liquid", and rich in vitamins A, D, E, K, and F, which are fat-soluble vitamins

that can be easily absorbed through the skin. Particularly, olive oil has a high vitamin

E content.

Peppermint is the aboveground part of the perennial root herb of the genus

Mentha in the mint family, which is a kind of aromatic crop with special economic

values. Menthol contained in the peppermint can accelerate the circulation in the body,

remove oiliness, relieve abdominal distension, resulting in the dissolving and burning of body fat, and the slimming. The essential oil extracted from peppermint can be used in aromatherapy and in perfumes and cosmetics to protect the skin. Peppermint contains volatile oil, peppermint essence, tannins and other substances, which can help to calm anger, depression and other negative emotions, and is a mental tonic to eliminate fatigue, relieve stress, and calm the mind.

Lavender is a plant of the genus Lavandula in the mint family, known as "quiet

perfume plant", "king of spices" and "queen of the aromatic herbs".

Viscose, the full name of viscose fiber, is extracted from natural lignocellulose

and reshaped with wood as raw materials. In the preparation process, plant cellulose is

alkalified to obtain alkaline cellulose, the alkaline cellulose is reacted with carbon

disulfide to obtain cellulose xanthate, followed by dissolution in dilute lye to obtain a

viscous solution called viscose, and then the viscose is subjected to wet spinning and

a series of processes to obtain a viscose fiber. The moisture absorption of the viscose

fibers can meet the physiological requirements of human skin. The viscose fiber is

smooth and cool, breathable, anti-static, anti-ultraviolet and colorful, and has a good

dyeing fastness. It has the essence of cotton and the quality of silk, and is an authentic

plant fiber. It is derived from natural but better than natural and widely used in

underwear, textiles, clothing, non-woven and other fields.

In the actual application, most of the viscose large biological fibers have good air

permeability and anti-wear effects; however, during the wearing process, the

antibacterial effect will decrease with washing, and in the process of washing, it is

often impossible to protect the skin. The oil produced by the skin can easily lead to

the growth of skin bacteria, and the large viscose biological fibers can easily fade,

resulting in a decrease in aesthetics.

SUMMARY

An object of the present disclosure is to provide a viscose large biological fiber

containing active ingredients of Albizia julibrissin, olive, peppermint and lavender

and a method for preparing the same. Through the viscose large biological fiber and

than 2 h. A concentration of the ethanol solution is 95%; the heated extraction solution

is centrifugated at 500 r/min for 20 min; and the supernatant is obtained after standing

a centrifugated solution for 1 h. The centrifugation can improve the efficiency for

extracting flavone and avoid wasting the active ingredient. The ethanol solution with

the concentration of 95% can efficiently absorb flavone. (3) The active ingredients of

Albizia julibrissin, olive, peppermint and lavender are concentrated through sealing

the supernatant and transporting the supernatant to a macroporous resin under

pressure followed by elution to obtain a concentrated flavone solution. The

supernatant is sealed and pressurized under a pressure of 0.2 MPa. The elution is

performed for no less than 1 h with absolute ethanol passing through the macroporous

resin. (4) A cellulose pulp is impregnated with an alkaline solution to obtain alkali

mesh, 0.005-0.05 g of a coupling agent, 0.006-0.07 g of a surfactant and the

is added followed by a second shear. A stabilizer is added followed by force shear

dispersion to obtain a stable nanocomposite suspension dispersion. A solvent of the

stable nanocomposite suspension dispersion is volatilized to obtain a dry porous

molecular nest containing an extract of the active ingredients of Albizia julibrissin,

olive, peppermint and lavender. A viscose spinning dope is pre-mixed with weakly acidic polyacrylamide. The macroporous adsorbent resin is a porous skeleton structure, and is prepared through cross-linking polymerization of styrene and propionate as monomers. Phenylethylene is used as a crosslinking agent.

Methylbenzene and dimethylbenzene are used as pore-forming agents. Generally,

resin is white spherical particles with a particle size of 20-60 mesh, and is a type of

cross-linked polymer containing ion exchange groups. The resin has stable physical

and chemical properties that the resin is insoluble in acids, alkalis and organics, and

not affected by inorganic salts and strong-ionic low-molecular compounds. The resin

adsorption is based on the van der Waals forces between the resin and adsorbed

molecules (adsorbents). The resin works by physical adsorption through its huge

specific surface, such that organic compounds can be separated by a certain solvent

according to their adsorption capacity and molecular weight to achieve different

purposes such as separation, purification, impurity removal and concentration. (5) The

dry porous molecular nest is modified and protected through adding a sufficient

ethanol solution to the dry porous molecular nest to combine sodium alginate/chitosan

to prepare a protective film, so as to obtain a modified molecular nest. (6) The viscose

is evenly mixed with the modified molecular nest followed by wet spinning to obtain

the viscose large biological fiber containing the active ingredients of Albizia

julibrissin, olive, peppermint and lavender. (7) A sufficient fixing agent is injected

into the viscose large biological fiber followed by steam color-fixing treatment.
