Description

Novel dyeing and finishing process for polyester fabric
Technical Field
The invention belongs to the technical field of textile fabrics, and particularly relates to a novel dyeing and finishing process for a polyester fabric.
Background
The terylene fabric is a chemical fiber garment fabric made of terylene fibers, has the advantages of good crease resistance and high shape retention, and is widely applied to various coat fabrics. The dyeing and finishing process of the polyester fabric is generally the same as other fabrics, and generally comprises four steps of pretreatment, presetting, dyeing and post-setting, but the dyeing steps in the prior art all have the problem of insufficient color fastness to a certain degree, and finally the fabric fades in a relatively short time, so that a novel dyeing and finishing process which has high color fastness and is difficult to fade after long-term use is urgently needed in the market.
The Chinese patent with patent publication number CN 109440502A and publication number 2019.03.08 discloses a dyeing and finishing process of a terylene sun-shading cloth fabric, which comprises the following steps: turning over cloth and sewing up the ends, pre-treating and removing impurities, pre-shaping, dyeing and fixing color, washing and floating color, post-treating and shaping.
However, the dyeing and finishing process in the patent of the invention has the problem of insufficient dyeing fastness.
Disclosure of Invention
The invention aims to provide a novel dyeing and finishing process for a polyester fabric, which can achieve the effect of effective dyeing by sequentially dividing the dyeing step into five operation modes of dye liquor preparation, dye liquor heating and heat preservation, dyeing, drying and color fixation. The invention has the advantages of reasonable and effective dyeing steps, high dye color fastness after dyeing, difficult fading of the fabric after long-term use, good zoned steam color fixing effect and further improved color fastness.
The technical scheme adopted by the invention for solving the problems is as follows: the utility model provides a novel dyeing and finishing technology for dacron surface fabric, includes these four steps of preliminary treatment, pre-setting, dyeing and back design in proper order, the dyeing step includes in proper order that the dye liquor is prepared, the dye liquor heating keeps warm, dye-uptake, stoving and the five step operations of fixation, in the dye liquor preparation operation, add dyestuff, retardant, fixing agent and softener, the fixation operation adopts the steam heating mode to realize the fixation.
In the invention, the retarding agent is combined with the polyester fiber firstly and then is gradually substituted by the dye in batches, so that the dyeing speed is reduced, the problem of large-range chromatic aberration is avoided, and the relatively low-speed and stable coloring effect is ensured.
The further preferred technical scheme is that the following preparation is carried out in the dye liquor preparation operation by weight:
0.20-0.25g/L of retarding agent;
0.10-0.15g/L of color fixing agent;
0.3-0.8g/L of softening agent,
wherein the dye is a disperse dye, and after the dye solution is prepared, the pH is adjusted to 4.0-4.3 by dripping glacial acetic acid.
The further preferred technical scheme is as follows: the dye retarding agent is an amine salt cationic surfactant, the color fixing agent is a cationic quaternary ammonium salt high polymer, and the softening agent is a cationic long-chain aliphatic softening agent.
In the invention, the retarding agent, the color fixing agent and the softening agent are all cationic and are matched with the disperse dye without water-soluble groups, so that the stable dyeing effect of the dye on the polyester fiber is ensured. On the other hand, under an acidic condition, the main chain of the quaternary ammonium salt high polymer and the polymerization structure of the long-chain fat are more stable and are not easy to dissociate.
The further preferred technical scheme is as follows: in the dye liquor heating and heat preservation operation, the heating temperature of the dye liquor in the high-temperature high-pressure dyeing machine is 130-132 ℃, and the heat preservation and dyeing time is 8.0-8.5 min.
The further preferred technical scheme is as follows: in the drying operation, the drying temperature is 100-120 ℃, and the drying time is 15-18 min.

In the invention, the four color fixing areas are different in steam temperature, fabric passing and color fixing time and color fixing additive composition, so that the dye layer is gradually adhered and solidified on the fiber layer by layer, and the color fastness is further improved.
The further preferred technical scheme is as follows: the steam temperature of the primary color fixing area is 80-85 ℃, the time for passing and fixing the color of the fabric is 15-19min, and the steam color fixing additive of the primary color fixing area comprises acrylic resin accounting for 15-45% of the weight of the steam and cationic polyacrylamide accounting for 2-8%.
In the invention, the acrylic resin has the effects of light and color retention, and the problem of fading gradually caused by illumination in a relatively short time is avoided in the use of the fabric, and the cationic polyacrylamide can prevent the environment of cations of the uncured dye layer main body from being damaged through the property of cations, and the cationic polyacrylamide has the adsorption and adhesion effects to fix dye components on polyester fibers, so that the color fastness is greatly improved.
The further preferred technical scheme is as follows: the steam temperature of the main color fixing area is 115-122 ℃, the steam pressure is 0.3-0.5MPa, the time for passing and fixing the color of the fabric is 25-28min, and the steam color fixing additive of the main color fixing area comprises cationic polyacrylamide accounting for 4-12% of the weight of steam, polyoxyethylene alkanolamide accounting for 1-3% of the weight of the steam and ethylene glycol accounting for 0.1-0.2% of the weight of the steam.
In the invention, compared with the primary color fixing zone, the main color fixing zone increases the steam temperature, the steam pressure and the color fixing time, and the polyoxyethylene alkanolamide and the glycol are additionally added, wherein the polyoxyethylene alkanolamide is a nonionic surfactant and used as a softener and a smoothing agent, and the polyoxyethylene alkanolamide is a wetting agent to ensure the effective adhesion and the function of the polyoxyethylene alkanolamide on the dye layer.
On the other hand, the softener, the smoothing agent and the wetting agent are added after the dye and are used for dip dyeing on the dye layer along with the steam, so that the competition relationship with the retarding agent is avoided, and the interaction of the two functions of retarding and leveling and the auxiliary softening and smoothing is not influenced.
The further preferred technical scheme is as follows: the steam temperature of the rear fixing area is 80-85 ℃, the time for the fabric to pass through and fix the color is 3-5min, the steam fixing additive of the primary fixing area comprises acrylic resin accounting for 15-45% of the weight of the steam and cationic polyacrylamide accounting for 2-8%, and the fabric returns to the steam generation area of the primary fixing area after passing through the main fixing area.
In the invention, the fabric is operated in a loose mode in the color fixing area, the equipment area of the post color fixing area is the same as that of the primary color fixing area, except for the color fixing time, other conditions are the same, and the post curing molding operation is carried out on the outer side of the dye layer.
The steam temperature of the auxiliary color fixing area is 60-62 ℃, the time for the fabric to pass through and fix the color is 25-28min, and the steam color fixing additive of the auxiliary color fixing area comprises acrylic resin accounting for 3-9% of the weight of the steam.
In the invention, the auxiliary color fixing area is positioned at the end, and the outer color fixing is carried out on the dye layer which is cured and formed only by using the acrylic resin used as the auxiliary color fixing together with steam with lower temperature, so that the fading period is further prolonged.
The dyeing method sequentially comprises the steps of dye liquor preparation, dye liquor heating and heat preservation, dyeing, drying and color fixation, so that the effective dyeing effect is achieved. The invention has the advantages of reasonable and effective dyeing steps, high dye color fastness after dyeing, difficult fading of the fabric after long-term use, good zoned steam color fixing effect and further improved color fastness.
