Abstract
The invention discloses a kind of based on fibroin with the weight increasing method of the silk fabric of plasma technology, the method comprises the following steps: first dissolves silkworm silk with commercial run and prepares silk fibroin solution, then silk fabric is immersed in silk fibroin solution after Low Temperature Plasma Treating immediately, taking-up silk fabric is after steam processes, and washing and drying obtains the silk fabric of fibroin weightening finish.This preparation method uses non-thermal plasma trap that fibroin is grafted on the surface of silk fabric, and percent grafting is high, and uniformity is good, and efficiency is high, low cost, environmental protection.Silk fabric prepared by this method not only weight substantially increases, it is ensured that the high-quality performance of silk fabric itself, and water-fastness, beneficially dyeing and finishing post-treatment.
Description
Technical field:
The invention belongs to silk product technical field, particularly to one based on fibroin and plasma
The weight increasing method of the silk fabric of technology.
Background technology:
Silk fabric is always with elegant softness, noble magnificent and beautiful in colour well-known, and silkworm silk is main
Comprising fibroin and sericin, the quality of the silkworm silk after degumming can reduce about 25%, and diameter also can reduce,
Therefore grammes per square metre and the stiffness of silk fabric can be affected, if producing weight pound silk, needs
High weft density, not only spends a large amount of silkworm silk raw material, and strengthens production difficulty.
The weightening finish of silk fabric arranges at present mainly following several ways: stannum weightening finish, tannin increase
The methods such as the weightening finish of weight, Sericin Gumming, glycerol polymerization weightening finish and silk fibroin solution weightening finish.Stannum increased weight
How can affect the dyeability of silkworm silk, and silkworm silk can be made to become fragile variable color；Weighting with Tannic Acid can cause silkworm
The color of silk is the most bright-coloured, is not suitable for the silk fabric of light color；Glycerol polymerization weightening finish is grafting
Uniformity is difficult to control, and is unfavorable for follow-up dyeing；Sericin Gumming weightening finish needs by aldehyde
Analog derivative, heavy metallic salt, tannins, N methylol compound and Cyanuric Chloride class material,
Do not meet the requirement of environment-friendly products, and through the flexibility of silkworm silk of Sericin Gumming and dyeability the most not
Good.
Silk fibroin solution weightening finish is to utilize free amine group in silk fibroin aqueous solution, hydroxyl, carboxyl etc. to live
Property group and silkworm silk macromole on active group form hydrogen bond, sat linkage, ester bond and Van der Waals force
Deng, through the Color increase of the silkworm silk of silk fibroin solution weightening finish, and washing shrinkage significantly declines,
Stiffness and wrinkle resistance have a certain degree of increase.Therefore silk fibroin solution weightening finish is silk fabric
The developing direction that weightening finish is new in arranging.
Chinese patent CN 201220334770.6 (grant date 2013.01.09) discloses one
Durable wire silk shell fabric, covers the mixed layer of one layer of fibroin and chitosan on the surface of silk thread, promotes
Antibody Monoclonal ability, color fastness and the wrinkling resistance of silk fabrics.Chinese patent CN
200910101493.7 (publication date 2009.12.30) discloses the silk egg of a kind of silk relics
White compound system bionic reinforcement method, immerses silk relics silk fibroin solution and shrinks sweet with ethylene glycol bisthioglycolate
The mixed solution of oil base ether soaks, increases the intensity of silk relics, reinforce silk relics
Performance.The method that current silk is reinforced is all that silk fibroin solution is directly overlayed silk fabric
On, or reinforced on silk fabric by chemical cross-linking agent, this reinforcement means not environmentally or is tied
Make a concerted effort the strongest.
Summary of the invention:
It is an object of the invention to provide a kind of silk fabric based on fibroin and plasma technology
Weight increasing method, by the group on non-thermal plasma trap activation silkworm silk surface, by fibroin equably
It is combined in silkworm silk surface, after alcohol steam processes crystallization, obtains the silk fabric of weightening finish.
The method can make silk fabric uniformly combine fibroin, and can guarantee that the quality of silkworm silk
Can, be conducive to dyeing.
The purpose of the present invention is achieved through the following technical solutions:
A kind of based on fibroin with the weight increasing method of the silk fabric of plasma technology, its feature exists
In, the method comprises the following steps:
(1) silkworm silk waste or leftover bits and pieces are gone the removal of impurity, enter with sodium bicarbonate aqueous solution
Row degumming, after calcium chloride water is expanded, is placed in sodium hydrate aqueous solution and dissolves,
Finally neutralizing the Acidity of Aikalinity of solution, dialysis is concentrated to give the silk fibroin solution that mass fraction is 5-10%；
(2) silk fabric is refined, wash, the moisture content that is dried to silk fabric is 10-15%,
It is then placed in Cement Composite Treated by Plasma instrument, is passed through oxygen, nitrogen or air, at the back of the body of 1Pa
Low-temperature plasma under the discharge power of bottom pressure, 150-200Pa operating pressure and 200-300W
Body processes 5-10min, then for 1:40, silk fabric is immersed step (1) with bath raio and prepares
Silk fibroin solution in soak 1-2h, obtain be grafted fibroin silk fabric；
(3) silk fabric of grafting fibroin step (2) obtained is taken out from silk fibroin solution,
Crystallization is obtained through the mixed vapour process 20-30min of the second alcohol and water that volume ratio is 3:2
Silk fabric, finally washes, and 55 DEG C are dried to obtain silkworm silk face based on fibroin and plasma technology
Material.
When above-mentioned Low Temperature Plasma Treating, if discharge power is little, process the time short, to silkworm
The activation on silk surface is inadequate, and percent grafting is undesirable, if it is big to put a power, processes the time long, right
Silk fiber can cause damage.
Compared with prior art, the invention have the advantages that
(1) present invention uses the active group on non-thermal plasma trap activation silkworm silk surface, as
Carboxyl, hydroxyl and amino etc., the power processed by regulation and time chien shih silkworm silk surface activity base
The uniform maximum activity of group.
(2) being mostly fibroin macromole in silk fibroin solution, fibroin macromole is had by silkworm silk surface
Strong adsorption, by soaking, fibroin macromole can be evenly distributed in silk fiber
Surface, is grafted with the active group on silkworm silk surface, and percent grafting is high and is evenly distributed, it is to avoid
The non-uniform phenomenon of chemical graft occurs.
(3) present invention uses fibroin to be solidificated in the surface of silk fabric, while weightening finish not
Change the high-quality character of silkworm silk itself, and processed the silkworm silk crystallization making surface by steam,
Improve the resistance to water of silk fabric.
(4) non-thermal plasma trap is applied to fibroin grafting silk fabric by the present invention, solves
Pollution problem to environment in conventional grafting weight gaining technology, and the silk fabric after being grafted
Composition does not change, and still remains original property, and is conducive to dyeing.
