Abstract
The invention provides an ecological method for performing integral dyeing and ultravioresistant finishing on woolen fabrics and silk fabrics by adopting grape seed extract. Safe, nontoxic and environment-friendly ultravioresistant textiles have broad market prospect. The method mainly comprises the following process steps of: pickup of natural grape seeds, extraction, filtration, centrifugal separation, preparation of the grape seed extract, and direct dyeing or aluminum ion and iron ion pre-mordant dyeing and ultravioresistant function finishing of the grape seed extract over the woolen fabrics and the silk fabrics. Compared with untreated woolen fabrics and silk fabrics and fabrics which have the same colors and are obtained by the dyeing of synthetic dyes, the woolen fabrics and the silk fabrics treated by the grape seed extract have high ultraviolet protection coefficients and low ultraviolet UVA and UVB transmittance, and namely have a powerful ultravioresistant function.
Description
Technical field
The present invention relates to the Application Areas of plant extracts, be specifically related to the grape pip extract and on wool, silk fabric, dye and carry out uvioresistant function arrangement, platymiscium dyeing and finishing functions technical field at textiles.
Background technology
Along with industrial expansion, industrial waste gas causes atmosphere pollution, depletion of the ozone layer.Past it is believed that it is to pursue healthy sunbath, nowadays but becomes the mercilessness " sun killer " that threatens human health.Depletion of the ozone layer, ultraviolet ray transmissivity increases, and the human cutaneum carcinoma probability of suffering from increases.Have the expert to foretell, to latter stage in this century, the incidence of disease of cutaneum carcinoma will leap to first of all kinds of diseases, become human No.1 killer.Therefore, people study the protection from ultraviolet rays product just energetically, increase sharply like sales volumes such as uvioresistant cosmetics, antiultraviolet fabrics.The antiultraviolet fabric meets the requirement that people like to be beautiful, keep healthy, and also can improve value-added content of product simultaneously, the enhancing of Along with people's growth in the living standard and health care consciousness, and the antiultraviolet textile product has vast market prospect.
At present; The sun-screening agent that uses in the uvioresistant cosmetics can be divided into two types: one type is ultra-violet absorber; Be organic compound (p-aminobenzoic acid class, salicylic acid, cinnamic acid etc.) can reduce or complete ultraviolet radiation-absorbing, but majority to have excitant; Another kind of is ultraviolet light screener, is nano level TiO
2, ZnO, but the excessive easy obstruction pore of consumption.So the wide and safety of the sun-proof spectrum of screening, active component and develop be the major subjects that cosmetic industry is studied efficiently from plant origin widely.The production of antiultraviolet fabric mainly contains two kinds of methods: a kind of is to make the uvioresistant function fiber earlier, and then processes the antiultraviolet fabric; Another kind is that fabric is carried out anti-ultraviolet finishing and obtains uvioresistant performance.The uvioresistant persistent that the uvioresistant function fiber is obtained, washable, anti-boiling hot property is good, but its production technology more complicated, to the requirement of ultraviolet absorber also than higher.The anti-ultraviolet finishing processing technology is fairly simple, and the range of choice of ultraviolet absorber is wide, but the washing resistance of uvioresistant effect is relatively poor.
Grape is one of whole world fruit of widely cultivating, according to statistics, the whole world year malaga surpass 100,000,000 tons, China's year malaga also surpasses 5,000,000 tons, but also is increasing year by year.Global grape has 80% to be used for brew grape wine approximately, and 7% is used to process fruit juice and other grape product, and grape pip is the accessory substance that in the grape process, produces; Account for the 4%-6% of whole grain grape weight; Therefore, China's grape pip annual production reaches ten thousand tons of 20-30, aboundresources and being easy to get.Contain the 5%-8% OPC in the grape pip; OPC is the general name that is present in the natural polyphenol compound of one big type of biflavone derivative in the plant; Constitute by polyhydroxy flavan-3-alcohol unit; The effect of have strong anti-oxidation, efficiently catching the aqueous favoring free radical and improving microcirculation in human body has purposes widely in fields such as medicine, cosmetics and health foods.
The pigment main component is an OPC in the grape pip extract; Belong to a big flavonoid class compound; Flavone compound can absorb ultraviolet ray, and being considered to has protective effect to plant tissue, makes it avoid ultraviolet ray burn; So the grape pip extract not only has the dyeing function, and has uvioresistant function.Austria Thomas Bechtold etc. has studied the dyeability of grape pip dyestuff to COTTON FABRIC.But up to the present, the research of giving woolen uvioresistant function simultaneously as wool fabric dyeing with the grape pip extract does not also appear in the newspapers.
Summary of the invention
The object of the present invention is to provide a kind of grape pip extract with multiple medicinal efficacy to wool fabric, silk fabric dyeing and make it possess the method for good uvioresistant function; This method existing dyeing installation capable of using; Need not increase new equipment, not increase cost.
For realizing the object of the invention; Adopt following main technique step: natural grape seed → extraction → filtration → centrifugation → grape pip extract → employing grape pip extract carries out direct dyeing or aluminium ion, the preparatory mordant dyeing look of iron ion, uvioresistant function arrangement to wool fabric, silk fabrics, more than the concrete characteristic of each step following:
The first step: natural grape seed extracts
With fresh or dry natural grape seed; Extract with deionized water or deionized water, alcohol mixed solvent; Extraction process is characterized as: deionized water, alcohol quality percentage are 25-100: 0-75; The solvent for use quality is 10-30 a times of grape pip quality, extracts 50-100 ℃ of temperature, extraction time 60-180min;
Second step: grape pip extracting liquid filtering
Adopt 80-200 order metallic sieve that the grape pip extract is carried out coarse filtration, remove filter residue;
The 3rd step: grape pip extract centrifugation
Adopt centrifuge that the grape pip extract is carried out centrifugation at normal temperatures, rotating speed 3000-5000 rev/min, centrifugation time 10-20min collects supernatant, promptly obtains grape pip extract transparent, clarification;
The 4th step: adopt the grape pip extract that wool fabric, silk fabrics are carried out direct dyeing or aluminium ion, the preparatory mordant dyeing look of iron ion, uvioresistant function arrangement
Adopt the grape pip extract; The technology characteristics of wool fabric, silk fabrics being carried out direct dyeing is: grape pip extract consumption is 1g wool fabric, silk fabrics 5-10ml, and bath raio is 20-40, and dye bath pH value is 3-7; Dyeing temperature is 50-100 ℃, and dyeing time is 60-180min.Be wool fabric, the silk fabrics that obtains different colours, can adopt aluminium mordant KAl (SO
