Description
Technical field
The present invention provides a kind of regenerated celulose fibre and preparation method thereof, and particularly a kind of suppression containing active component adds
Regenerated celulose fibre of age smelly body odour and preparation method thereof.
Background technology
Regenerated celulose fibre, industrialized production is achieved that early in 20 beginnings of the century.Because it has the performance close with cotton,
Regain meets human body skin psychological need, while having the advantages that ventilative, smooth, antistatic, easy dyeing, application field is wide
It is general, there is extensive application in health care, home textile, clothes etc..It is fine using regenerated cellulose with continuing to develop for science and technology
Dimension feature, the various new functional fibers with regenerated celulose fibre as matrix are constantly succeeded in developing, and further expand regeneration fine
Cellulose fiber market.
Functional fiber can improve the added value of its textile product, lift the function and class of textile product, meet many
Unitization takes demand, so design turns into the focus of textile industry with research and development new type functional fiber product.Meanwhile, with people
The improvement of consumption idea, own health is increasingly paid attention to, green, environmental protection, the functional fiber of health will have wide
Market prospects.Human body accumulates one kind and is claimed in order to prevent the dry skin from sebum can be voluntarily secreted out of from sebaceous glands, in sebaceous glands
Be palmitoleic acid（9- gaidic acids）Aging material, the aliphatic acid can give reactive oxygen species, become lipid peroxidation
The stink substance of matter.Particularly after people is 40 years old, the secretory volume of the palmitoleic acid in sebum starts to increase, and anti-oxidant energy
Power declines, and causes palmitoleic acid in human sebaceous to be easier to be oxidized and produce 2- nonenyl aldehydes, give out similar candle, cheese,
The peculiar smell of secondhand book.
In addition human skin's bacterial fermentation can also produce unsaturated aldehyde, emit bad smell.This peculiar smell is commonly called as " plus age
It is smelly " or " old man's taste ".At present, occur in that some reduce perfumed soap, cosmetics, bath foam that body odour occurs on the market.However, these
Product is used and carries inconvenience, it is impossible to suppress peculiar smell in time.
The content of the invention
In view of the shortcomings of the prior art, the present invention is to solve people with age（After 40 years old）Body can dissipate
Send the body odour problem that one kind is referred to as " old man is smelly " or " plus age is smelly ", there is provided a kind of suppression containing active component adds age smelly body
Regenerated celulose fibre of taste and preparation method thereof, to realize following goal of the invention：
（1）The regenerated celulose fibre of obtained suppression plus age smelly body odour containing active component of the invention is to staphylococcus aureus
Bacteriostasis rate, the bacteriostasis rate to Escherichia coli, the inhibiting rate to Candida albicans it is higher；
（2）The regenerated fiber disposition fiber of obtained suppression plus age smelly body odour containing active component of the invention, physical index is very
It is good；
（3）The regenerated celulose fibre of of the invention obtained suppression plus age smelly body odour containing active component, active component content compared with
It is high；
（4）The suppression plus the active component of age smelly body odour that the present invention contains can increase the water lock amount of skin surface, while suppressing
The speed of sebum secretion palmitoleic acid, and ketopalmitic acid oxidation product 2- nonenoic acids are decomposed, reduce the probability of happening for adding age smelly；
（5）The regenerated celulose fibre of suppression plus age smelly body odour containing active component of the invention, is made T-shirt ready-made clothes, wearing one
Zhou Hou, to obvious decrease effect sent with old man plus age smelly body odour, the smell with human body substantially dies down.
