B finishing agent preparation: shitosan is adopted certain glacial acetic acid dissolving, handle and add hydrogen peroxide solution behind the certain hour and degrade, filter, the collecting precipitation thing makes the shitosan of degraded.
Composite: as B finishing agent and C citric acid slowly to be joined in the A liquid, add auxiliary reagents such as a certain amount of bleeding agent, softener again, fibroin/shitosan that must be stable/citric acid anti-wrinkle shrink-proof finishing agent.
(2) put in order: COTTON FABRIC is put in fibroin/shitosan/citric acid finishing padded, get product after oven dry bakes.
In the step (1), when A liquid prepared, the concentration of NaOH was 1～5mol/L, and the waste silk consumption is 1%～10%, and hydrolysis temperature is 100 ℃, and hydrolysis time is 30～120min; When B arrangement thing prepares, take by weighing certain amount of chitosan, it is added in the entry, add a certain amount of glacial acetic acid again, stir 24h down, shitosan fully is dissolved in the acetum at 30～60 ℃.Slowly add 30% hydrogen peroxide solution then at a certain temperature, behind reaction 1～3h, filter collecting precipitation; B finishing agent and C citric acid are joined in the A liquid, and A and B solid content ratio are 4: 1, and the citric acid consumption is 1%～10%
The concrete grammar of step (2) is: cotton fabric is put into fibroin/shitosan/citric acid finishing working solution pad, pick-up rate is 90%, and padding is two to soak two and roll; Then at 80 ℃ of following preliminary drying 5min, handle 3～5min down at 100～150 ℃ again, wash then, dry product.
Useless silk has a certain amount of free active group through washing the fibroin finishing agent that makes after the hydrolysis, like hydroxyl, phenolic hydroxyl group, amino etc., can form stable combining through covalent cross-linking or physical deposition with cotton fiber is intermolecular.Thereby improve the anti-wrinkle shrink-proof performance of cotton fiber.
The shitosan film forming is strong; And with the cellulose chemistry structural similarity, they have good absorption and compatibility, and the amino hydroxyl with fiber of the hydroxyl of shitosan and a part forms numerous intermolecular hydrogen bondings; Add proper amount of cross-linking agent, make the shitosan arrangement can play certain anti-wrinkle shrink-proof wrinkle effect.
Citric acid has more reactive group, can form covalent cross-linking with hydroxyl on the COTTON FABRIC, simultaneously, and the crosslinking agent that can also close as other finishing agents and cotton knot.
Fibroin hydrolyzate, degradation of chitosan thing and citric acid under certain pH condition, are re-dubbed stable finishing agent by a certain percentage, have cooperative effect, and need not to add in addition crosslinking agent, make the all-cotton fabric after the arrangement have preferable anti-wrinkle shrink-proof effect.
The present invention is a raw material with useless silk, shitosan and citric acid; The three all belongs to the natural green health-oriented products; Using the ecological non-ironing textile high-grade fabric of this finishing agent exploitation to meet the 21 century finishing functions of textile fabrics should carry out as keynote with safety with comfortable, cleaning and put the direction of processing in order; Wherein contain a large amount of fibroin albumens in the fibroin finishing agent, have skin-friendly preferably, and catered to the consumption concept of people " environmental protection, health, fashion ".
The advantage that the present invention is compared with prior art had:
1, finishing agent adopted is product harmless, environmental protection.The consumption concept that meets " environmental protection, health, fashion ".
2, only contain hydroxyl on the all-cotton fabric, after arrangement, contain fibroin albumens such as part amino, phenolic hydroxyl group on the fabric, human body skin is had compatibility preferably.Can improve the sucting wet air permeability and the snugness of fit of cotton fiber.
3, do not add crosslinking agent, adopt citric acid as crosslinking agent, the fabric after the arrangement does not contain has the material that stimulation is toxic or ecological textile is forbidden to human body.
