Abstract
The invention discloses a low-temperature oxygen bleaching scouring agent and a preparation method thereof, wherein the low-temperature oxygen bleaching scouring agent comprises the following components in percentage by weight: 1-10% of bismuth-based catalyst, 2-12% of crown ether surfactant, 5-15% of Bola surfactant, 10-20% of green surfactant, 1-5% of cosurfactant and 35-80% of water. The low-temperature oxygen bleaching scouring agent prepared by the invention is efficient and environment-friendly, can reduce the scouring and bleaching temperature from 98 ℃ to 45-65 ℃, and can also obviously improve the effective utilization rate of hydrogen peroxide, so that the consumption of the scouring agent is reduced by about 35% compared with that of the conventional scouring agent, and the COD (chemical oxygen demand) of discharged wastewater is reduced by 35-45%; the stability to metal ions in water is strong, the reduction of scouring and bleaching effect and the serious damage to cotton fibers cannot be caused, and the applicability is wide; the whiteness, capillary effect, strength and polymerization degree of the scoured and bleached fabrics are obviously superior to those of the conventional scouring agent.
Description
Technical Field
The invention relates to the field of pretreatment auxiliaries in the printing and dyeing industry, in particular to a low-temperature oxygen bleaching scouring agent and a preparation method thereof.
Background
The cotton fabric is well liked by consumers with excellent performance and occupies a main position in the textile, but the natural cotton fiber contains various impurities and needs to be pretreated, thereby facilitating subsequent dyeing and finishing processing or improving the wearability. The traditional desizing, scouring and bleaching pretreatment process has long route, high energy consumption and large pollution discharge, is gradually eliminated, and is the most commonly used high-temperature strong-alkali scouring and bleaching one-bath process taking hydrogen peroxide as a bleaching agent at present. However, the method is not only easy to damage the fiber, but also not in line with the requirements of energy conservation, emission reduction and environmental protection and the development trend of the industry and the society. Therefore, the low-temperature pretreatment technology of cotton fabrics becomes the key research and development direction of the industry, and receives extensive attention and intensive research.
At present, two methods for low-temperature pretreatment at home and abroad are mainly used, one method is to adopt a biological enzyme preparation for treatment, but conventional desizing enzyme and scouring enzyme cannot be used in one bath with hydrogen peroxide, and need to be carried out step by step, and the treatment effect is not satisfactory, so that the method is only suitable for partially dark-dyed varieties. For example, the cotton fabric treated by neutral low-temperature refined enzyme and its application in the pretreatment of fabric (publication No. CN 102154230B) adopts refined enzyme, has poor wax removability and poor whiteness, and cannot be used for dyeing light-colored or bright-colored fabric. The other method adopts an activation system to realize low-temperature pretreatment, and comprises two main types of activators and catalysts. Wherein the activator comprises acyl, saccharide, guanidine, cyanogen, etcAnd H 2 O 2 The reaction generates a new substance with stronger oxidability, and the bleached cotton fabric is decomposed at low temperature; the catalyst is mainly an enzyme-imitating metal complex which comprises metal phthalocyanines, nitrogen-containing macrocyclic metals and Schiff base metals, and promotes the decomposition of hydrogen peroxide at a lower temperature to achieve the traditional scouring and bleaching effect. However, the activating system also has various problems, or poor water solubility, and is inconvenient to use; or the structure is complex, the price is high, and the industrialization is difficult; or the bleaching effect is not ideal. For example, in the document "structural characterization and application of low-temperature oxygen bleaching activator TAED" (printing and dyeing, 2010, no. 19), the activator TAED is adopted to bleach cotton fabrics, so that the effect is excellent, but the problems of poor water solubility, large dosage and high cost of the TAED exist.
In the research of the low-temperature pretreatment technology, a plurality of scholars mainly research how to promote hydrogen peroxide bleaching at low temperature, but the effective decomposition rate of hydrogen peroxide is easy to ignore. In the high-temperature strong-alkali scouring and bleaching bath, the cotton fabric can be bleached by the effective decomposition of hydrogen peroxide, but the fibers can be damaged by oxygen generated by ineffective decomposition under the conditions of high temperature and strong alkali, so that the fabric is broken, and the strength and the polymerization degree are reduced. In a conventional high-temperature strong-alkali scouring and bleaching bath, the dosage of hydrogen peroxide is 6-8g/L, but the actual decomposition rate of the hydrogen peroxide is only about 70%, the activation system only reduces the decomposition temperature of the hydrogen peroxide but cannot improve the effective decomposition rate, so that the waste of the hydrogen peroxide is caused, the residual hydrogen peroxide can also obviously increase the COD value of wastewater, the subsequent dyeing of fabrics is decolored, and the dosage of dye is increased. In addition, in actual production, due to regional differences, rusty pipeline equipment, different water sources and the like, the water quality used for pretreatment is different, the water quality has great influence on the effectiveness of hydrogen peroxide, the water hardness is high (the contents of Ca and Mg are high), and the efficiency of the hydrogen peroxide can be reduced; heavy metal ions in water, such as Cu, fe, cr and Zn, can catalyze hydrogen peroxide to be rapidly decomposed, so that hydrogen peroxide is wasted, a large number of free radicals can be generated in a short time, and excessive free radicals can act on cellulose to cause serious damage to the fiber and even generate holes.
Therefore, the development of a low-temperature oxygen bleaching scouring agent which can promote the decomposition of hydrogen peroxide under the low-temperature condition, can improve the effective decomposition rate and is suitable for various water qualities meets the requirements of social and industrial development, and is a problem to be solved urgently by technical personnel in the field.
