Problems solved by technology

Due to its excellent safety, durability, slow release and chemical stability, and convenient use, inorganic antibacterial materials have been more and more important applications. It is easy to disperse into the plastic, which makes it difficult to play an effective role; at the same time, the inorganic antibacterial agent in the polypropylene fiber masterbatch is easy to cause aggregation, uneven distribution and poor mixing effect, resulting in difficulty in spinning and forming, low fiber strength, and wearing Sensitivity and poor air permeability
The function is also relatively simple, and it is obviously lacking in skin care and health care such as anti-ultraviolet radiation, promoting new cell regeneration, improving cell activity, enhancing skin cell immunity, delaying aging, removing spots and whitening, and cannot promote beneficial changes in human body functions and skin

preparation example Construction

[0040] The antibacterial agent is Fe-doped zinc oxide nanosheets, and the Fe-doped zinc oxide nanosheets are prepared by the following steps:

[0041] S1. Weigh Zn(NO 3 ) 2 ·6H 2 O and Fe(NO) 3 9H2 O, stirred and dissolved in deionized water to obtain Zn 2+ and Fe 3+ The mixed solutions with ion concentrations of 0.3mol / L and 0.1mol / L were added to the mixed solution with a final concentration of 0.7mol / L, and after stirring and dissolving, they were transferred to a reaction kettle with a polytetrafluoroethylene liner and sealed. , reacted at a constant temperature at 120-130°C for 24 hours under autogenous pressure, cooled naturally to room temperature after the reaction was completed, separated the precipitate and washed it with deionized water, dried and ground to obtain powder A;

[0042] S2. Add polyethylene glycol dropwise in deionized water to obtain a mixed solution A, ultrasonically disperse the powder A obtained by grinding in the mixed solution A, transfer it ...

Embodiment 1

[0065] An antibacterial skin care polypropylene fiber masterbatch, by weight, has the following components:

[0066]

[0067] Wherein, the plant extract is centella asiatica extract and honeysuckle extract;

[0068] The preparation method of the centella asiatica extract is as follows: after the dried centella asiatica is crushed, it is extracted by adding ethanol with a volume fraction of 80-90%, the ratio of solid to liquid is 1:40-80, and the extraction is assisted by ultrasonic waves. centrifugation or suction filtration, and collect the filtrate; add activated carbon to the filtrate for decolorization, centrifuge, collect the decolorization filtrate, concentrate the decolorization filtrate, add macroporous adsorption resin for purification, elute with ethanol to obtain an eluent, and After the eluent is concentrated, desalted and dried, the Centella asiatica extract is obtained;

[0069] The preparation method of the honeysuckle extract is as follows: take dried honey...

Embodiment 2

[0079] On the basis of Example 1, the antibacterial skin care polypropylene fiber masterbatch also includes 3 parts of hydrophobically modified polysaccharide derivatives; the preparation method of the hydrophobically modified polysaccharide derivatives is:

[0080] Weigh 4-dimethylaminopyridine and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride respectively and dissolve them in dimethyl sulfoxide. After fully stirring and dissolving, add mass Polysaccharide-dimethyl sulfoxide solution with a fraction of 10%, and then one of the C18 fatty acids was added dropwise, stirred and reacted for 36 hours in a water bath at 36-40°C, and absolute ethanol was added after the reaction was completed, and the precipitate was precipitated after standing, filtered The precipitate was washed successively with absolute ethanol and ether, and vacuum-dried to obtain the hydrophobically modified polysaccharide derivative;

[0081] Wherein, the 4-dimethylaminopyridine and the 1-(3-dime...

Abstract

The invention provides an antibacterial skin-care polypropylene fiber master batch, which belongs to the field of functional fiber master batches and fabrics. The master batch comprises the following components by weight: 30-60 parts of polypropylene resin, 3-15 parts of a plant extract, 8-25 parts of an antibacterial agent, and 2-10 parts of an auxiliary agent. The plant extract is a plant extract with a skin care effect. The antibacterial agent is Fe-doped zinc oxide nanosheets, the Fe-doped zinc oxide nanosheets are prepared by preparing Zn-Fe hydroxides with hydrotalcite-like layered structures through a secondary hydrothermal method and then roasting in high-purity nitrogen to obtain a zinc oxide nanosheet having an oxygen defect, the surface polarity of zinc oxide is reduced, the agglomeration trend is reduced, and the compatibility with polypropylene melt is improved.

Description

technical field [0001] The invention relates to the field of functional fiber masterbatches and fabrics, in particular to an antibacterial and skin-care polypropylene fiber masterbatch and fabrics. Background technique [0002] Polypropylene fiber (polypropylene fiber), commonly known as polypropylene fiber, is a fiber made of propylene as a raw material through polymerization and melt spinning. Because of its rich source of raw materials, low price, simple production process, light weight and softness, and excellent moisture conductivity, perspiration, warmth retention, mildew and moth resistance, etc., it is widely used in clothing, decoration and industrial products. In particular, it is easy to blend with natural fibers or chemical fibers to form fabrics, which is very suitable for making underwear, T-shirts, bed sheets and other textiles that are in direct contact with human skin. However, because the above-mentioned fabrics do not have antibacterial skin care function...
