Abstract
To overcome the defects of indigo dyeing existing in the prior art is not easy deep dye, dyeing temperature is higher, the present invention provides a kind of indigo dyeing method of 56 fiber of polyamide or 56/ cotton blended spinning face fabric of polyamide.Bipseudoindoxyl dye is not required to that, using conventional dip method, ideal dye level just can be reached at normal temperature by extra process.
Description
Technical field
The invention belongs to textile printing and dyeing fields, and in particular to a kind of 56 fiber of polyamide or 56/ cotton blended spinning face fabric of polyamide
Colouring method and products thereof.
Background technique
Polyamide fabric is the first synthetic fibers occurred in the world, its synthesis is the great prominent of synthetic fiber industry
Broken, its appearance makes textile fabric field take on an entirely new look.Relative to traditional pure-cotton fabric, by cotton fiber and polyamide 6, polyamides
The chemical synthetic fibers such as amine 66 or terylene are blended, can enhance the wearability and intensity of fabric.Cotton fiber is blended with spandex, it can
Assign fabric excellent elasticity, but spandex fibre has low strength, easy fracture, easily loses the disadvantages of elasticity.In general, pure cotton
Or cotton blended spinning face fabric indigo dyeing uses room temperature multiple tracks exhaust process, but under normal temperature condition, polyamide 6 in blended fabric,
It is dark that polyamide 66, terylene or spandex component are not easy dye, and Yi Fasheng shows money or valuables one carries unintentionally phenomenon.
" indigo dye and dyeing of nylon fibre, Cao's machine are good etc., " printing and dyeing ", using bipseudoindoxyl dye to poly- in 2014.No.20 "
Nylon is dyed, and the dosage of sodium hydrosulfite, caustic soda, sodium chloride and dyestuff, the works such as oxidization time and dyeing temperature have been inquired into
Influence of the skill parameter to dyed fabric K/S value.The raising (being higher than 60 DEG C) with dyeing temperature is pointed out in document, fabric K/S becomes
Change little, it is contemplated that high temperature is conducive to the infiltration and diffusion of bipseudoindoxyl dye, it is proposed that take 100 DEG C to be used as dyeing temperature.
Summary of the invention
To overcome the defects of indigo dyeing existing in the prior art is not easy deep dye, dyeing temperature is higher, the present invention is provided
A kind of indigo dyeing method of 56 fiber of polyamide or 56/ cotton blended spinning face fabric of polyamide.Bipseudoindoxyl dye is not required to by extra process,
Using conventional dip method, ideal dye level just can be reached at normal temperature.
The present invention provides a kind of indigo dyeing method of 56 fiber of polyamide or 56/ cotton blended spinning face fabric of polyamide, including such as
Lower step:
56 fiber of polyamide or 56/ cotton blended spinning face fabric of polyamide are dyed using bipseudoindoxyl dye；
Dyeing temperature is 20-60 DEG C, preferably 20-30 DEG C；
The bipseudoindoxyl dye includes vegetable indigo dye and/or artificial synthesized bipseudoindoxyl dye；
56 fiber of polyamide is 56 long filament of polyamide and/or short fibre；
56/ cotton blended spinning face fabric of polyamide is polyamide 56 and cotton fiber blended yarn weaved fabric.
The indigo dyeing method of heretofore described 56 fiber of polyamide or 56/ cotton blended spinning face fabric of polyamide specifically include with
Lower step:
(1) by bipseudoindoxyl dye under the conditions of reducing agent and caustic soda abundant reduction of dissolved, be configured to leuco compound dye liquor, it is spare；
(2) 56 fiber of polyamide or 56/ cotton blended spinning face fabric of polyamide are totally submerged the procrypsis described in step (1)
In body dye liquor, sufficiently dye；
(3) 56 fiber of polyamide after sufficiently dyeing or 56/ cotton blended spinning face fabric of polyamide are taken out, are exposed in air,
It is fully oxidized；
(4) fully oxidized 56 fiber of poststaining polyamide or 56/ cotton blended spinning face fabric of polyamide are soaped, drying or from
So dry.
In above-mentioned colouring method, reducing agent described in step (1) is sodium hydrosulfite.
In above-mentioned colouring method, sodium hydrosulfite concentration described in step (1) is 20-30g/L, and the concentration of caustic soda is 2-6g/
L。
In above-mentioned colouring method, the reduction of dissolved time described in step (1) is 20-30min, and reduction of dissolved temperature is 40-
60℃。
In above-mentioned colouring method, dyeing time described in step (2) is 5-30min.
In above-mentioned colouring method, oxidization time described in step (3) is 15-30min.
In above-mentioned colouring method, technique of soaping described in step (4) is soaping agent concentration 2-5g/L, and temperature of soaping is 70-
80 DEG C, the time of soaping is 10-15min；
In above-mentioned colouring method, drying temperature is 50-70 DEG C in the step (4).
The present invention still further provide a kind of 56 fiber of indigo dyeing polyamide prepared by above-mentioned colouring method and/or
56/ cotton blended spinning face fabric of polyamide.
Dyed fabric provided by the present invention, color is uniform, and color fastness to washing can meet subsequent dress or requirement.
The invention has the following advantages:
Polyamide 56 is a kind of novel Fypro, and compared with polyamide 6, polyamide 66, the raw material that it is used is
Ferment from various biomass the pentanediamine of preparation through biological engineering method, belongs to bio-based materials.Biology base fiber has green
The good characteristics such as color, environmental-friendly, raw material be renewable and biodegradable.Polyamide 56 has many excellent characteristics, intensity
Close to polyamide 66, good hygroscopicity, antistatic property is good, and wearability is good, and pliability is close to wool.
Polyamide 56 is odd even type carbon atom arrangement, and non-centrosymmetry is presented in strand, and amido bond density is high, and fiber is non-
There are the more amido bonds for having neither part nor lot in hydrogen bond formation for crystalline region, therefore, in dyeing course, are conducive to hydrone inside and outside fiber and exchange
And dye material diffusion, to have low temperature dyeing characteristic.Bipseudoindoxyl dye leuco compound can diffuse into polyamide at normal temperature
The amorphous area of 56 fibers, on macromolecular chain amino and amide groups occur electrostatic force, Van der Waals force, hydrogen bond the effects of power
In conjunction with, after air oxidation, it is reduced to bipseudoindoxyl dye state in fibrous inside, thus make 56 fibre staining of polyamide, solution
Traditional cotton/synthetic fiber fabric indigo dyeing shows money or valuables one carries unintentionally phenomenon.Dyeing temperature is normal when the indigo dyeing of polyamide 56 of the present invention
Near temperature, the energy is saved, and the low damage to fabric of dyeing temperature is smaller.
