Abstract
The invention discloses a dyeing technology of polyamide fibers, comprising the following steps: (1) adding soda ash Na2CO3 in water until the pH value of the water is 8.8-9.2, adding the cloth in the water with the ratio of the cloth to the water being 1lg:10L, adding dyes telon yellow, telon blue, telon emerald blue to the water and mixing to form a dye liquor, and adding levelling agent to the dye liquor, wherein weight ratio of the telon yellow to the cloth is 0.045:1, the weight ratio of the telon blue to the cloth is 0.015:1, the weight ratio of the telon emerald blue is 0.24:1, and the weight ratio of the levelling agent to the cloth is 0.04:1; and (2) heating up the dye liquor to 70 DEG C, then adding acid-releasing agent to the dye liquor, wherein the ratio of the acid-releasing agent to the water is 0.4g:1L, and the acid-releasing agent is added to the dye liquor at a speed of 0.0067-0.008g/min to reduce the pH value of the dye liquor to 6.5. According to the invention, the technology dyes the cloth uniformly, and greatly reduces the cost of repair or rework.
Description
Technical field
The present invention relates to a kind of dyeing, specifically a kind of dyeing of nylon fibre.
Background technology
In recent years, increasingly mature along with polyamide fibre elastomer market, the nylon fabric product is more and more used.Because client's demand, nylon fabric can be dyed various colors according to actual needs.In the market the demand of the nylon fabric of bright-colored constantly increased, wherein demand is large especially for the nylon fabric of emerald green blue look.In the process to textile dyeing, need to dye any color, just need to adopt the ACID DYES of corresponding color.Wherein the uneven problem of more dyeing has appearred in ACID DYES with emerald green Lan Sewei representative when in use, causes the fabric quality of finished not high, affects market sales volume.This kind phenomenon is because colouring is too fast after dyestuff reaches the colouring condition, causes local colouring too much, thereby causes whole colouring uneven.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of certain technique of nylon fibre, and it is more even to paint, and has promoted the quality of finished product.
In order to solve the problems of the technologies described above, the present invention takes following technical scheme:
A kind of dyeing of nylon fibre may further comprise the steps:
(1) in water, adds soda ash Na
2CO
3Until the pH value of water is 8.8-9.2, add cloth in water, the proportion of this cloth and water is that 1 kilogram of KG:10 rises L, then adds yellow, day imperial blue and emerald green orchid of day dragon of dyestuff sky dragon in the water, water and dyestuff are mixed into dye liquor, dyestuff sky dragon is yellow counts 0.045:1 by weight with cloth, and the imperial indigo plant in dyestuff sky is 0.015:1 with cloth by weight percentage, and the emerald green orchid of dyestuff sky dragon and cloth are 0.24:1 by weight percentage, also be added with levelling agent in the dye liquor, this levelling agent and cloth are 0.01:1 by weight percentage;
(2) dye liquor is heated to 70 ℃ after, in dye liquor, add acid-releasing agent, the acid-releasing agent of adding and the proportion of water are that 0.4 gram G:1 rises L, join in the dye liquor with the speed of 0.0067-0.008 grams per minute, until the pH value of dye liquor drops to 6.5.
Behind the pH value 6.5 of described dye liquor, heating makes dye liquor be warming up to 95 ℃～98 ℃, and is incubated 30 minutes when temperature is 95 ℃～98 ℃.
The yellow model of dragon was M-5GL in described day, and a day imperial blue model is M-2R, and the model of day emerald green orchid of dragon is M-5G.
The invention solves traditional handicraft and paint too fast and colouring problem of non-uniform that cause, reach the effect of even dyeing, effectively promoted the quality of finished product, greatly reduce the repair rate of cloth and the cost of reforming, for enterprise has reduced production cost.
The specific embodiment
For the ease of those skilled in the art's understanding, the invention will be further described below in conjunction with accompanying drawing.
The present invention has disclosed a kind of dyeing of nylon fibre, may further comprise the steps:
