Abstract
The invention discloses a method for preprocessing mulberry silk by chitosan modified liquid, which relates to preparation of silk and silk products. The method comprises the steps of: dissolving chitosan powder containing water in an acetic acid solution, uniformly mixing the solution with sodium beta-glycerophosphate to obtain mulberry silk fiber modification liquid, immersing mulberry silk fibers in the modification liquid, performing vacuum drying on the fibers and the like. Furthermore, a fabric made of the preprocessed mulberry silk is dyed with acid dyes at a low temperature and under the condition of neutral dye bath. The strength, the creasy recovery angle, the moisture absorption and the water absorption of the fabric are improved, and a dyeing effect, the color fastness and the leveling property of the fabric are satisfactory.
Description
Technical field
The present invention relates to the preparation of silk and goods, especially washable, wrinkle resistant textiles mulberry silk and the preparation method of goods.
Background technology
Shitosan (chitosan) is the chitin deacetylase derivative, is the linear polysaccharide of a kind of natural boiomacromolecule.At occurring in nature, shitosan extensively exists, and annual biosynthetic stock number is the second largest living resources that are only second to string on the earth up to 10,000,000,000 tons.Shitosan can be used as the permanent finiss agent of fabric, occurs to change mutually at fabric with liquid state, forms semisolid preparation, improve the fastness of fabric, make fabric water-fastness, wear-resisting wiping, fixation and humidification are arranged, reduce crimp contraction, and make fabric have smooth bright and clean and well-pressed outward appearance and feel.
Dissaving polymer is different from general linear polymer, has nearly chondritic, low, the terminal features such as a lot " nano-void ", easy film forming that exist with a large amount of groups, intramolecule of viscosity.The dissaving polymer of film-forming can be used as infiltrating and vaporizing membrane (PV), and " nano-void " of hyperbranched polymer molecule inside can make different solution molecules selectively see through, and reaches the purpose of separation.Pertinent literature " preparation of dissaving polymer cross linking membrane and the research of performance " (Wei Yanfei, Zhu Baoku; Zhejiang University) (HPAE) obtains HPAE-GA cross linking membrane and the crosslinked HPG cross linking membrane of dianhydride with the crosslinked HPG of dianhydride with glutaraldehyde (GA) crosslinked hyperbranched poly-(amine-ester) respectively.Wherein, the HPAE-GA cross linking membrane, good hydrophilic property, higher swellbility and increase with solvent polarity, the swelling in water be greater than 66%, fracture strength 13.7Mpa.Be 100pm, aldol when separating the isopropyl alcohol of moisture 10wt% than the crosslinked G4-HPAE-GA cross linking membrane that obtains of 1:1 with thickness, separation factor (α) is 45.1, and permeation flux (J) is 1568g/m ~ 2h.And with 3,3 ', 4,4 '-BPDA (BPDA), 3 ', 4,4 '-benzophenone tetracarboxylic dianhydride (BTDA) and 4,4 '-the two phthalic anhydrides (ODPA) of oxygen are the crosslinked HPG of crosslinking agent, the HPG homogeneous membrane is larger than the TENSILE STRENGTH of glutaraldehyde cross-linking HPAE homogeneous membrane, wherein the hydroxyl acid anhydride than be 4 the crosslinked HPG homogeneous membrane of ODPA fracture strength up to 43.7Mpa, the swellbility of the crosslinked HPG homogeneous membrane of ODPA in water is higher than other two kinds of films.What the document related to is HPG or the research of HPAE dissaving polymer permeable membrane.
Summary of the invention
For the performance of improving silk fiber and the added value that improves silk product, the present invention seeks to by preparing chitin modified liquid, it is applied to cocoon fiber and fabric are carried out in the modification, obtain washable, wrinkle resistant mulberry silk fiber and textiles.
The object of the invention realizes in the following manner:
Moisture chitosan powder is dissolved in the acetic acid solution of 0.1mol/L, the volume ratio of shitosan and acetic acid solution is (3 ~ 4): 1, again with this solution and sodium β-glycerophosphate with volume ratio 10:(1 ~ 2) stir, degas bubble as the mulberry silk fiber modification liquid, mulberry silk fiber is immersed in the modification liquid, 32 ℃ of water-bath 2h ~ 3h, vacuumize obtains the preliminary treatment mulberry silk.
Described method further is to use acid dyeing at a lower temperature with under the condition of neutral dye bath through the fabric of preliminary treatment mulberry silk.
The present invention has following good effect:
Mulberry silk fiber internal structure of the present invention is βization trend, and relative crystallinity and heat endurance improve, and the powerful enhancing of textiles, and creasy recovery angle increases, and hygroscopicity improves, and water imbibition also strengthens.
Fabric of the present invention adopts acid dyeing, can be at a lower temperature with the condition of neutral dye bath under carry out, and Color, COLOR FASTNESS and level-dyeing property are satisfactory.
The specific embodiment
Embodiment 1:
Moisture chitosan powder is dissolved in the acetic acid solution of 0.1mol/L, the volume ratio of shitosan and acetic acid solution is 3:1, again this solution and sodium β-glycerophosphate are stirred with volume ratio 10:1, degas bubble as the mulberry silk fiber modification liquid, mulberry silk fiber is immersed in the modification liquid, 32 ℃ of water-bath 2h ~ 3h make the even adsorption of modification liquid of mulberry silk fiber, and it is dry to take out final vacuum, obtains the preliminary treatment mulberry silk.
Embodiment 2:
The fabric of preliminary treatment mulberry silk is used acid dyeing at a lower temperature with under the condition of neutral dye bath.
Claims (2)
1. the method for a chitin modified liquid preliminary treatment mulberry silk (silk) is characterized in that:
Moisture chitosan powder is dissolved in the acetic acid solution of 0.1mol/L, the volume ratio of shitosan and acetic acid solution is (3 ~ 4): 1, again with this solution and sodium β-glycerophosphate with volume ratio 10:(1 ~ 2) stir, degas bubble as the mulberry silk fiber modification liquid, mulberry silk fiber is immersed in the modification liquid, 32 ℃ of water-bath 2h ~ 3h, vacuumize obtains the preliminary treatment mulberry silk.
2. method according to claim 1 is characterized in that and will use acid dyeing at a lower temperature with under the condition of neutral dye bath through the fabric of preliminary treatment mulberry silk.
