Description
Technical Field
The invention relates to the technical field of color modifiers, in particular to a novel environment-friendly color modifier and a preparation method thereof.
Background
The terylene is an important variety in synthetic fibers and is also the synthetic fiber with the largest market share in the world at present, and is the commodity name of the polyester fiber in China. The basic component of terylene is polyethylene glycol terephthalate with molecular formula [ -OC-Ph-COOCH2CH2O-]nAnd small amounts of monomers and cyclic oligomers. Because of the presence of a large number of ester groups on the molecular chain,and is therefore referred to as polyester fiber (PET). The terylene has compact molecular structure, high crystallinity and orientation degree, the glass transition temperature is higher than 80 ℃, so that the terylene is difficult to dye, and dye molecules are difficult to diffuse into fibers, so disperse dyes with simple structures are usually adopted for dyeing, the dyeing method of the disperse dyes comprises a hot melting method, a carrier dyeing method and a high-temperature high-pressure method, the hot melting method is generally applied to a continuous pad dyeing process for dyeing the polyester-cotton blended woven fabric, the carrier dyeing method mainly aims at an intermittent dyeing process of the polyester-wool blended fabric and the like, the dyeing temperature of which can not exceed 105 ℃, the high-temperature high-pressure method belongs to an intermittent high-temperature dyeing process, the dyeing process is generally completed under the condition of 125 ℃ and 135 ℃, various varieties such as yarns, loose fibers, fabrics and the like can be dyed, and the terylene and the blended fabric thereof are the most extensive dyeing processing mode at present.
In actual production, color spots, stains and stains are problems which are often encountered in high-temperature and high-pressure dyeing methods. The slight color can be repaired in a stripping and re-dyeing mode, and the serious color can not be repaired frequently, so that defects can be picked, trimming can be avoided, goods can be supplemented or the products can be folded in the subsequent process, and great economic loss is caused to a factory.
Cause analysis of color spots, stains and stains: one is that the cyclic trimer (about 75 percent, the solubility is less than 2mg/kg) with low degree of polymerization associated in the process of synthesizing the polyester fiber is gradually resolved and dissociated from the fiber after the dyeing temperature exceeds 120 ℃, because the solubility is ultralow, the cyclic trimer is often combined with dye in the process of dyeing and cooling, and is deposited on the surface of fabric or equipment during liquid discharge to form dyeing defects; and the other is related to the added dispersant in the disperse dye. The molecules of the disperse dye mainly contain hydrophobic groups, the solubility in water is low, and a large amount of anionic dispersant (more than 40-60%) is usually added in the commercialization process to disperse and suspend the disperse dye in an aqueous solution to complete the dyeing process. However, due to cost and market competition factors, different choices of dispersants by various manufacturers result in differentiation of dyes.
In order to achieve better dyeing effect, a proper amount of high-temperature resistant dispersant is usually required to be additionally supplemented during dyeing so as to obtain uniform dyeing effect. Such as carriers, polyepoxide compounds, and other anionic/nonionic type dispersion leveling compounds. The action mechanism is as follows:
a. the polyepoxy compound can increase the solubility of the disperse dye, and the components of the polyepoxy compound contain a large number of polyethylene glycol chain segments, so that the polyepoxy compound has a strong solubilizing effect on the dye and can promote the adsorption of the disperse dye on the fiber surface; but has the disadvantages of low dye utilization rate (low dye uptake percentage), cloud point problem, poor dispersibility at high temperature and easy dye agglomeration;
b. the carrier can plasticize the fiber, reduce the Tg of the fiber, accelerate the diffusion speed of the disperse dye in the fiber and achieve the aim of uniformity; the disadvantages are that the initial dyeing rate is high, the dyeing is easy to cause colored flowers, and the environmental protection performance of part of carriers is not enough (such as large toxicity and odor residue);
c. the anionic component in the anionic/nonionic type dispersing leveling agent can be adsorbed on the surface of dye molecules to form an electric double layer, dye ions form a stable dispersed state due to strong electrostatic repulsion, the nonionic component has a leveling effect, and the two components meet the requirement of dyeing leveling in a copolymerization or compounding manner; the anionic/nonionic disperse leveling agent is a widely used dyeing leveling agent product at present, but has the defects of non-ideal reconditioning effect, capability of guaranteeing normal dyeing requirements and difficulty in meeting the reconditioning requirements once dyeing is reconditioned.
Therefore, it is necessary to develop a novel environment-friendly level dyeing and color modifying agent which can simultaneously realize level dyeing and color modification, does not contain prohibited components, has low (no) air temperature, low ammonia nitrogen and no phosphorus, and meets the market demand.
