Description
Technical field
The present invention relates to a kind of production method of textiles, is a kind of production method of metal-modified polypropylene fiber specifically.
Background technology
Polypropylene fibre is to be formed by the propylene monomer isotaxy, does not contain any polar group in the molecule, and the degree of crystallinity height has very high hydrophobicity again, does not especially contain in the molecule to dye seat with dyestuff is had an effect, so polypropylene fibre dyeing is extremely difficult.After polypropylene fibre was succeeded in developing, people were seeking effective colouring method always, and wherein blending method, copolymerization method, grafting method, surface modification etc. demonstrate huge potentiality to be exploited, become dyeable polypropylene hot of research and development in recent years.By introducing the dyeing and finishing expert, integrate school and Enterprise Resource, the great potential that polypropylene fibre is taken decoration market is sought in integrated innovation.
Summary of the invention
Goal of the invention: the objective of the invention is to overcome the deficiencies in the prior art, a kind of production method of metal-modified polypropylene fiber is provided, the polypropylene fiber that this method is produced can dye dark color and COLOR FASTNESS height.
Technical scheme: in order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of production method of metal-modified polypropylene fiber, this method comprises the steps:
1) olefines high polymer and polypropylene fiber are obtained blend polypropylene fibre at 200～280 ℃ of melt blendings, wherein the addition of olefines high polymer is 3～8% of a polypropylene fiber weight;
2) the blend polypropylene fibre that obtains in the step 1) being dropped in the color pond, is to add water at 5: 1 by bath raio then, stirs, and is incubated 30～50min, cooling after being warming up to 80 ℃;
3) hydrosol of adding doped metal ion, the speed with 4～6 ℃/min heats up then, is 90～120 ℃ until temperature, running 30min; The addition of the wherein said hydrosol is 0.6～3% of a blend polypropylene fibre weight;
4) the clear water washing promptly gets described metal-modified polypropylene fiber.
In the step 1), described olefines high polymer is a polyethylene.
The addition of described olefines high polymer is 6% of a polypropylene fiber weight.
In the step 3), metal doping rate≤1% in the described hydrosol.
The olefines high polymer all exists with unbodied state in blended fiber, and polypropylene then great majority is present in the fiber with crystal form.Decline by a big margin along with the increasing gradually of olefines high polymer addition as, the degree of orientation of fiber when adding small amounts of olefins class high polymer, degree of orientation fall reduces gradually.Cause fibre structure loose, have more amorphous region to produce.Because the thermal property and the interfacial property of polypropylene and olefines high polymer there are differences, there is a large amount of boundaries between the inner two-phase of blended fiber, formed a large amount of micropores between the boundary.Especially when olefines high polymer content acquires a certain degree as, micropore in the blended fiber begins mutual perforation, thereby for the diffusion of dye molecule provides the duct, can diffuse into fibrous inside easily, and by means of Van der Waals force, dye molecule is adsorbed in the electron conjugated effect of phenyl ring ∏, thereby reaches the purpose of dyeing.With the isotactic polypropylene co-blended spinning, a spot of olefines high polymer makes in the fiber can produce a large amount of groove and micropore, help the dyeing of fiber, and when olefines high polymer addition position 6%, the micropore of boundary begins to interpenetrate, the degree of crystallinity and the degree of orientation of fiber are more little, and the balance dye-uptake of fiber is the highest.Metal in the fiber can form coordinated complex with the organic compound of polarity.During dyeing, dyestuff and metal-modified polypropylene fibre generation chemical reaction, the dissociation constant of the complex compound of formation is very little, so very stably be present in the fiber, is difficult to take off, so COLOR FASTNESS is very high; The polypropylene fibre that this method of while obtains can be dyed dark color.
Beneficial effect: compared with prior art, the polypropylene fiber that adopts the present invention to produce can dye dark color and COLOR FASTNESS height.
