Abstract
The invention discloses a kind of linen and preparation method thereof with safeguard function,It include the pretreatment of linen,Oxidation processes,The preparation of chitosan acetic acid solution,The preparation of chitin modified oxidation linen and tea polyphenols are to preparation processes such as the composite finishings of chitin modified linen,The present invention uses periodic acid or periodate to be selectively oxidized linen first,Imidization can be occurred with the chitosan containing NH2 by generating active group aldehyde radical CHO,Under conditions of without using any crosslinking agent or other chemical addition agents,The two produces chemical bonding,Fabric is enhanced during postorder arranges to the adsorption capacities of tea polyphenols,Promote the combination of tea polyphenols and linen,Tea polyphenols finishing functions process is avoided to use other reagents,The product of the present invention has good antibacterial,Crease-resistant and uvioresistant etc. is multi-functional；The preparation process of the product is simple, easy to operate, and cleanly production is also achieved in preparation process, meets the requirement of ecological textile.
Description
Technical field
The present invention relates to a kind of method of modifying of linen, more particularly to one kind to have antibacterial, crease-resistant, uvioresistant etc. more
The processing method of functional linen.
Background technology
Flaxen fiber is native cellulose fibre, has the characteristics that recyclability, biodegradability and nontoxic and pollution-free.
Flaxen fiber is widely used in clothes, household and industry with its graceful gloss, good humidity absorption and release and natural antibacterial
With etc. textile fields.But there is the shortcomings of creasing easily, size is unstable in flaxen fiber；And when wearing summer, linen
Ultraviolet resistance also needs to further increase.As new varieties, high-performance and multi-functional textile fiber material continuously emerge,
Requirement objectively to flaxen fiber and its product is also higher and higher.The multifunction of exploitation flaxen fiber and its product is modified and carries
Its high added value and performance have become a general orientation of people's research.
Since the functional finishing agent developed at present is attached to flaxen fiber and its product surface by physical absorption mostly, still
The two combines insecure.Therefore it during flaxen fiber tradition is modified, needs using chemical cross-linking agent (resin, glyoxal, organosilicon and more
First carboxylic acid etc.) or coupling agent " bridging " effect its functional finishing agent is grafted on flaxen fiber, to reach improvement flaxen fiber
Performance and the purpose for assigning its function durability.However, flaxen fiber product tradition is modified, there are certain drawbacks, such as resin or second two
Aldehyde can make to remain and release formaldehyde on linen after arranging, and larger harm is generated to human body；And crosslinking agent or coupling agent grafting
Modified flaxen fiber surface has inevitably been crosslinked one layer of chemical substance, affects the good characteristic of natural ramie fiber, and right
Health has a negative impact.Therefore, traditional modification technology is while assigning flaxen fiber cellulose fiber product function, to life
The harm of state environmental and human health impacts is serious, it is difficult to meet ecological, multi-functional and persistent multiple requesting.
Tealeaves is the abundant natural plant resource in China, and tea polyphenols are more than the 30 kinds of phenol separated and extracted from tealeaves again
The complex of class compound, predominantly flavanols (catechin) class, accounts for the 60~80% of total amount.Tea polyphenols are special due to its
Ingredient and structure have many unique physiological activity, such as excellent oxidation resistance, radioresistance, anti-inflammation and sterilization, uvioresistant
Etc. functions, be widely used in the fields such as medicines and health protection, food processing, daily-use chemical industry, fine chemistry industry at present.Recent year
Outer researcher has carried out certain research using tea polyphenols as natural dye for textile dyeing and functional treatment, and tea is more
The modification of phenol can not only make fabric have unique color and luster, can also impart to many natural healthcare functions of fabric.But
The binding strength using chemical cross-linking agent or mordant enhancing tea polyphenols and fiber, meeting are usually needed in tea polyphenols dyeing and finishing process
It has a negative impact to environment or health, thus limits the application of tea polyphenols on the textile.
Chitosan is the deacetylated product of chitin, is unique alkaline polysaccharide in nature.Chitosan have it is nontoxic,
