A kind of Modal/cotton blended fabric dyeing
Technical field
Patent of the present invention is related to a kind of dyeing dyeing and finishing technology and in particular to a kind of Modal/cotton blended fabric dyeing.
Background technology
Modal is a kind of New Regenerated Cellulosic Fibers, the comfortableness of its existing cotton, has the drapability of viscose rayon again
With soft gloss.Modal fibre and cotton blended fabric have good gloss and pendency sense, soft comfortable, lovely luster;
Modal/cotton blended fabric containing spandex, in addition to the above-described advantages, has good elasticity simultaneously, is suitable as high-grade fabric, but should
There is the defects such as easy wrinkle, easily scratch fluffing and strength be not good in fabric, affect Color.
After the dyeing of Modal/cotton blended fabric because of two kinds of fibers the diversity to dyestuff dye uptake, lead to cloth cover color not
Uniformly, become depth fiber crops ash shape, affect guest plain color cloth cover quality.
Content of the invention
The purpose of the present invention is for problem present in above-mentioned, provides a kind of Modal/cotton blended fabric dyeing,
Solve Modal/cotton blended fabric with bath colouring uneven phenomenon, greatly improve the cloth cover quality of product.
The above-mentioned technical problem of the present invention is mainly addressed by following proposal: a kind of Modal/cotton blend is knitted
Thing dyeing, concrete technology comprises the following steps:
(a) pre-treatment: Modal/cotton blended fabric is put into cylinder body, water inlet, keep bath raio 1:9, add 3% white snow net
Cotton enzyme is warming up to 98 DEG C of operation 30min, draining;Water inlet keeps bath raio 1:9, adds 0.4% glacial acetic acid, room temperature cold row 10min;
Draining;Water inlet keeps bath raio 1:9 again, adds 0.12% deoxyenzyme, room temperature cold row 10min;
B () is dyeed: using 60 DEG C of constant temperature dyeing techniques to Modal/cotton blended fabric dyeing, Modal/cotton blend is knitted
Thing is placed in dye vat, and water inlet keeps bath raio 1:9, is warming up to 60 DEG C of holding constant temperature, adds 6% aviterase series dyes, unit
Bright powder 60~120g/l, soda 10~30g/l, dye 60~100min;
C () washes: after consistent with dyed plate contrast after dyeing, use clean water fabric;
(d) post processing: add the alkali liquor of 1% removal of surfactant fabric face, be warming up to 80 DEG C of holding 10min,
Repeat 2~3 times;The glacial acetic acid adding 0.5% adjusts ph to 7~7.5,60 DEG C of keeping temperature;Add 0.2% citric acid again
Adjust ph to 4.5;Add 8~10% soft dose of color and 0.5~1.5% color fixing agent to fabric further fixation, keep temperature
40 DEG C of degree, runs 20min;
E () washes: use clean water fabric;
(f) dewatered drying.
Preferably, adopting 60 DEG C of constant temperature dyeing techniques in described step (b) dyeing to Modal/cotton blended fabric
The concrete steps of dyeing: Modal/cotton blended fabric is placed in dye vat, water inlet keeps bath raio 1:9, is warming up to 60 DEG C and keeps permanent
Temperature, after running 10min, adds 1/3 Matrii Sulfas Exsiccatus in 15min after the avitera se series dyes adding 6% in 15min
Run 5min, the Matrii Sulfas Exsiccatus adding remaining 2/3 again in 15min run 20min;Interpolation soda at twice, wherein 1/3
Soda runs 5min after adding, then runs 80min after adding remaining 2/3 soda and complete to dye.
Because the level-dyeing property of existing dyestuff is poor, avitera se series dyes have that light fastness is excellent and level-dyeing property
Good, add Matrii Sulfas Exsiccatus and soda at twice respectively after adding dyestuff it is therefore prevented that dyeing flower phenomenon in dyestuff fabric in dyeing, shadow
First adjust the ph value of fabric after ringing Color, and dyeing, ph to 7~7.5 is adjusted by glacial acetic acid, due to glacial acetic acid volatility
By force, need to add citric acid to adjust ph to 4.5, after reaching standard, add soft dose of color and the further fixation of color fixing agent again.
Existing technology is compared, and advantages of the present invention is as follows: dyeing condition is gentle, and easy and simple to handle, environmental protection can guarantee that dyeing
Fiber strength, fabric whiteness and capillary effect etc. all reach coloration requirements afterwards.Avitera se series dyes are new high set activity
Dyestuff, substantivity is relatively low, level-dyeing property is good, bright in colour, and after dyeing, fabric items color fastness is more excellent.
Figure of description
Fig. 1 is the schematic diagram of dyeing of the present invention.
Specific embodiment
It is further discussed below the present invention with reference to embodiment and its accompanying drawing, but the present invention should not be limited by the examples:
Embodiment 1: as shown in figure 1, a kind of Modal/cotton blended fabric dyeing, concrete technology comprises the following steps:
(a) pre-treatment: the fabric 167kg of 40s50/50 cotton Modal+20d single jersey is placed in vertical letter eco-38 2t cylinder body
In, water inlet, keep bath raio 1:9, add the 3% net cotton enzyme of white snow to be warming up to 98 DEG C of operation 30min, draining;Water inlet holding bath raio 1:
9, add 0.4% glacial acetic acid, room temperature cold row 10min;Draining;Water inlet keeps bath raio 1:9 again, adds 0.12% deoxyenzyme,
Room temperature cold row 10min;
B () is dyeed: using 60 DEG C of constant temperature dyeing techniques to textile dyeing, using 60 DEG C of constant temperature dyeing techniques to Modal/
The concrete steps of cotton blended fabric dyeing: Modal/cotton blended fabric is placed in dye vat, water inlet keeps bath raio 1:9, is warming up to
60 DEG C of holding constant temperature, in 15min, addition 1.45%avitra se is yellow, 1.9%avitra se is red, 1.75%avitra se
After running 10min after blue series dyes, the Matrii Sulfas Exsiccatus adding 1/3 in 15min run 5min, add surplus again in 15min
The Matrii Sulfas Exsiccatus of remaining 2/3 run 20min;Add soda at twice, wherein 1/3 soda runs 5min after adding, then adds surplus
Run 80min after the soda of remaining 2/3 to complete to dye;
C () washes: after consistent with dyed plate contrast after dyeing, use clean water fabric;
(d) post processing: add the alkali liquor of 1% removal of surfactant fabric face, be warming up to 80 DEG C of holding 10min,
Repeat 2~3 times;The glacial acetic acid adding 0.5% adjusts ph to 7.5,60 DEG C of keeping temperature;The citric acid adding 0.2% again is adjusted
Section ph to 4.5;Add 9% soft dose of the color further fixation to fabric, 40 DEG C of keeping temperature, operation with 1% color fixing agent
20min;
E () washes: use clean water fabric;
(f) dewatered drying.
Because the level-dyeing property of existing dyestuff is poor, avitera se series dyes have that light fastness is excellent and level-dyeing property
Good, add Matrii Sulfas Exsiccatus and soda at twice respectively after adding dyestuff it is therefore prevented that dyeing flower phenomenon in dyestuff fabric in dyeing, shadow
First adjust the ph value of fabric after ringing Color, and dyeing, ph to 7~7.5 is adjusted by glacial acetic acid, due to glacial acetic acid volatility
By force, need to add citric acid to adjust ph to 4.5, after reaching standard, add soft dose of color and the further fixation of color fixing agent again.
Advantages of the present invention is as follows: dyeing condition is gentle, and easy and simple to handle, environmental protection can guarantee that fiber strength, fabric after dyeing
Whiteness and capillary effect etc. all reach coloration requirements.Avitera se series dyes are new high set reactive dye, direct relatively low,
Level-dyeing property is good, bright in colour, and after dyeing, fabric items color fastness is more excellent.
Compare with traditional handicraft color fastness testing result as table 1 using this technique that (color fastness examination criteria is iso 105
B02:2013):
Finally it is pointed out that above example is only the more representational example of the present invention.Obviously, the technology of the present invention
Scheme is not limited to above-described embodiment, can also have many variations.Those of ordinary skill in the art can be from disclosed by the invention
All deformation that content directly derives or associates, are all considered as protection scope of the present invention.
