Skill.
Background technique
Terylene is in textile using the synthetic fibers that relatively broad, comprehensive performance is more excellent.Terylene filament fabric is knitted
Starching must be carried out before making, and so that strand surface is coated one layer of smooth, flexible and firm serous coat, to enhance the obvolvent of polyester filament
Power and wearability enable to bear various frictional force and tension in weaving process, weaving production in good quality and high output
It asks down and goes on smoothly.Resistance polyester fiber knitting fabric is more soft relative to terylene woven fabric, is commonly used to production sun protection clothing, therefore polyester knitting
Cloth requires the color fastness after dyeing and finishing very high.
Polyester fiber is the hydrophobic fibre made of polyethylene terephthalate.Since terylene molecular chain structure is tight
It is close, lack the hydrophilic radicals such as carboxyl, sulfonic group and the dyeing such as direct dyes, acid dyes, basic dye cannot be used.Currently,
Dyeing and finishing technology to polyester fabric is first to carry out liquid alkaline desizing to polyester fabric, then will be starched again using after warm water cleaning for several times
The pH of liquid is adjusted to 6-6.5, is then immersed in dye liquor again, and dyestuff uses the simple disperse dyes of structure, after dyeing again
Reduction cleaning is carried out, then carries out neutralization cleaning again.
But disperse dyes molecule does not contain the hydrophilics groups such as carboxyl, sulfonic group, therefore water-soluble poor；Dispersion
Dyestuff is mixed with water, forms the suspension of dye liquor, and disperse dyes are easy to happen sedimentation；To cause the woven dacron after dyeing
Color fastness is low, causes resistance polyester fiber knitting fabric upper color contaminated under the natural environment of exposing to the weather to be easy to happen and fades.
Summary of the invention
The purpose of the present invention is to provide a kind of dyeings of resistance polyester fiber knitting fabric, by adding sulfomethylated lignin in dyestuff
Sour sodium and OP-10 make dyeing assistant, so that Monoazo type dyestuff has good water solubility, meanwhile, OP-10 makes Monoazo type
Dyestuff wetting prevents from agglomerating then generating sedimentation between Monoazo type dye molecule, so that terylene cloth color after dyeing
Fastness is higher, and the upper color contaminated is more longlasting under the natural environment of exposing to the weather.
Above-mentioned technical purpose of the invention has the technical scheme that
A kind of dyeing of resistance polyester fiber knitting fabric, it is characterised in that: fabric is subjected to following steps processing:
S1: fabric is subjected to pre-setting；
S2: the fabric after pre-setting is subjected to desizing；
S3: the fabric after desizing is subjected to washing neutralization；
S4: the fabric after washing is neutralized dyes, and each substance of dyestuff used is by percentage to the quality are as follows: monoazo
Type dye 5%-10%, sodium lignin sulfonate 3%-7%, OP-10 3%-7%, levelling agent 15%-25%, acetic acid 1%-3%
And water 48%-73%.
S5: the fabric after dyeing is subjected to continuous wash；

By using above-mentioned technical proposal, polyester fiber is hydrophobic thermoplastic fibre, and molecules align is neat, crystallinity
Height, the microgap between fiber molecule is small, without containing water soluble groups such as carboxyls, the space not accommodated for dye molecule, and wash
There are also hard-packed epidermis for synthetic fibre fiber surface；Since Monoazo type molecular structure of dye is simple, and relative molecular mass
It is small, so readily diffusing between polyester fiber molecule；The hydrophobicity of Monoazo type dyestuff is strong simultaneously, is more easier to be attached to
On polyester fiber；Sodium lignin sulfonate is the anionic surfactant of natural polymer, its hydrophobic group contaminates Monoazo type
Expect that molecule package can then make Monoazo type dyestuff so that the surface of Monoazo type dye molecule is hydrophilic radical
Molecular melting is in water.After Monoazo type dyestuff is dissolved in water, in the PET fiber surface that is gradually transferred to by solution,
Then when the Monoazo type dyestuff accumulation in PET fiber surface is excessive, Monoazo type dyestuff is from PET fiber surface to terylene
Fibrous inside diffusion, the Monoazo type dyestuff inside the concentration of the Monoazo type dyestuff of PET fiber surface and polyester fiber
Concentration it is identical when, i.e., upper dye reaches balance.So only dye molecule can be dissolved in water well, terylene just can be carried out
The dyeing and weaving of fiber.
OP-10 has good wetability, can be by the Monoazo type dye molecule moistened surface of cohesion, so that wooden
Plain sodium sulfonate can be wrapped up Monoazo type dye molecule with lesser unit, prevent Monoazo type dye molecule from coagulating mutually
Gather and settles.The alkali resistance of polyester fiber molecule is poor, and acetic acid can provide weak acid for the dyeing of polyester fiber molecule
The environment of property, and Monoazo type dyestuff can be stable in acidic environment upper dye between polyester fiber molecule.By
