Abstract
The invention discloses a bast fiber fabric with a protective function and a preparation method thereof. The preparation method comprises the preparation steps of bast fiber pretreatment, oxidation treatment, chitosan acetic acid solution preparation, chitosan-modified oxidized bast fiber fabric preparation, chitosan-modified oxidized bast fiber fabric composite finishing through tea polyphenol and the like. According to the preparation method, bast fiber is selectively oxidized through periodic acid or periodate, a generated active group aldehyde group -CHO can generate an imidization reaction with chitosan containing -NH2, chemical bonding is generated between the aldehyde group and chitosan containing -NH2 under the condition that no cross-linking agent or other chemical additive is used, therefore, the tea polyphenol adsorption capacity of the fabric in the subsequent finishing process is enhanced, combination between tea polyphenol and the bast fiber is promoted, and the condition that other reagents are used in the tea polyphenol function finishing process is avoided. The bast fiber fabric has the good multifunctionality such as the antibacterial property, the wrinkle resistance and the ultraviolet resistance; the preparation technology of the bast fiber fabric is simple and convenient to operate, clean production is achieved in the preparation process, and the requirements of ecological textiles are met.
Description
Technical field
The present invention relates to the method for modifying of a kind of ramie cotton fabric, particularly relate to one and to reach the polyfunctional hemps such as antibacterial, crease-resistant, uvioresistant
The processing method of thing.
Background technology
Flaxen fiber is native cellulose fibre, has recyclability, the feature of biological fall nontoxic pollution-free.Flaxen fiber is with the gloss of its gracefulness, good
Good humidity absorption and release and natural antibacterial and be widely used in the textile field such as clothing, domestic and industry use.But flaxen fiber existence creases easily, chi
The shortcomings such as very little instability；And when wearing summer, the ultraviolet resistance of linen also needs to improve further.Along with new varieties, high-performance and many
The textile fiber material of function constantly occurs, more and more higher in objectively requirement to flaxen fiber and goods thereof.Exploitation flaxen fiber and goods thereof are many
Functional modification and improve its added value and performance has become a general orientation of people's research.
Functional finishing agent owing to developing at present relies on physical absorption to be attached to flaxen fiber and product surface thereof mostly, but both combine insecure.
Therefore, in the modification of flaxen fiber tradition, need to use chemical cross-linking agent (resin, Biformyl, organosilicon and polybasic carboxylic acid etc.) or " bridging " of coupling agent
Its functional finishing agent is grafted on flaxen fiber by effect, thus reaches improve flaxen fiber performance and give the purpose of its function durability.But, fiber crops are fine
There is certain drawback in dimension tradition modification, can make remain on linen and discharge formaldehyde, human body is produced bigger harm after arranging such as resin or Biformyl；
And the flaxen fiber surface of cross-linking agent or coupling agent graft modification has inevitably cross-linked one layer of chemical substance, have impact on the excellent spy of natural ramie fiber
Property, and health is had a negative impact.Therefore, traditional modification technology is while giving flaxen fiber cellulose fiber product function, to ecological ring
Border and human health damage are serious, it is difficult to meet ecological, multi-functional and persistent multiple requesting.
Folium Camelliae sinensis is the natural plant resource of China's abundant, and tea polyphenols is again the complex of more than the 30 kind of phenolic compound that separation and Extraction goes out from Folium Camelliae sinensis,
Predominantly flavonol (catechin) class, it accounts for the 60～80% of total amount.Tea polyphenols is many unique physiology owing to its special composition and structure have
Activity, such as functions such as excellent oxidation resistance, radioprotective, anti-inflammation and sterilization, uvioresistants, has been widely used in medicines and health protection, food the most
