Description
One, technical field
The invention relates to a kind of colouring method of pupa albumen/viscose composite fiber, more particularly about a kind of pupa albumen/viscose composite fiber one-bath two-step process colouring method.
Two, background technology
Pupa albumen viscose glue/long filament is that silkworm chrysalis is extracted pupa albumen through dissolving, pupa casein albumen that obtains after the pulverizing and viscose glue raw material-cotton pulp dregs of rice blend by a certain percentage, the protein-modified viscose filament yarn that is obtained behind spinning moulding.
Because the pupa albumen of blend and the molecular structure of the cotton pulp dregs of rice have than big-difference, make the very easily free skin of pupa albumen that interface interaction power is weak, viscosity is less to viscose filament yarn, after the fiber filament moulding, pupa albumen always is enriched in around the skin of modification viscose filament yarn, thereby give the attribute of viscose filament yarn, become new varieties-pupa albumen/viscose filament yarn with protein fibre style with protein fibre.
But owing to have auburn pupa protein in a large amount of enrichments of fibrous outer, the dyeing that makes pupa protein viscose filament rayon not only Dry Sack is withered secretly, the color and luster that is difficult for dying bright-colouredly especially can not be processed into bright shallow, middle look product, and these have influenced the wearability of pupa albumen/viscose filament yarn greatly.
Pupa albumen/viscose filament yarn is a kind of pupa albumen/viscose composite fiber, and section morphology is the cauliflower shape, and is similar to the irregular zigzag of common viscose fiber.In fact, the forming process of composite fibre is to become fine high molecular concentrated solution to import same spinning head respectively with two kinds, after the suitable position of spinning head meets, sprays from same spinneret orifice, becomes core-skin type, parallel type and islands-in-sea type fibre.Common viscose glue is at ZnSO
4-H
2SO
4When being shaped in the coagulating bath, Zn
++Diffusion velocity is slower than H
+, Zn
++When diffusing to the somewhere arrival critical concentration of rayon spinning liquid stream, form the structuring center through 0.01-0.05 induction duration second, gel solidification becomes the fibrocortex structure.Subsequently, xanthate acid only relies on the H that is diffused into
+Neutralization and solvation and gelation, form core structure.The outermost layer of common viscose fiber is a rete, is cortex below the about 1-2um of thickness, rete, and area accounts for the long-pending 20-60% of entire cross section, and inside is sandwich layer.Therefore, can explain the structure of pupa albumen/viscose composite fiber with two cortexes-core structure model, outermost layer is the protein cortex, and this layer is thinner, and is sticking also with the viscose glue component, is viscose cortex and sandwich layer below.
At 20 ℃, under relative humidity 65% condition, silk regain 9%, and pupa protein viscose filament rayon regain 12.8% are near viscose regain 13%.Because the hygroscopicity of fiber is relevant with macromolecular chain structure, degree of crystallinity etc., the degree of crystallinity of viscose is 30-40%, and the degree of crystallinity of pupa protein viscose filament rayon also belongs to this category.The dry state fracture strength of pupa protein viscose filament rayon is 1.61 (cN/dtex), and common viscose glue is 1.93-2.61 (cN/dtex), and the former is the latter's 61-85%, illustrates that the degree of polymerization of pupa albumen/viscose filament yarn may be lower than about viscose degree of polymerization 250-390.On the other hand, the fracture strength of pupa protein viscose filament rayon is lower, and with degree of crystallinity, the degree of orientation of fibrocortex, and pupa protein molecular aggregated structure is relevant.
Because pupa albumen/viscose filament yarn has core-skin layer structure, cortex construction is tight, hinders the absorption and the diffusion of dyestuff, and core structure is loose, to the adsorbance height of dyestuff.So if with the low temperature short time dyeing, the viscose Dry Sack is shallow, and easily produces the uneven dyeing phenomenon, the dyeing of high temperature long period, viscose gets color depth.
