Abstract

The invention discloses a preparation method and application of a novel defoamer, which belongs to the technical field of application of dyeing auxiliaries. The preparation method includes the first step of preparing raw material components: celery leaves, sugarcane peels, bitter melon, ginkgo leaves, and mulberry leaves. , leaves of Polygonum multiflorum and fig leaves, the addition amount is based on dry matter weight, the second step is to prepare a water extraction concentrate, the third step is to prepare an ethanol extraction concentrate, and the fourth step is to mix the concentrate and add sodium chloride and soybean powder to mix evenly A new type of defoamer is obtained. The defoamer of the present invention uses plant extract flavonoids as the main active ingredient. The processing and preparation method is simple, environmentally friendly and pollution-free, and meets the social needs of sustainable development. It is applied in textile slurry, and its The addition amount is 0.1‑0.5% of the weight of the textile slurry. It has good defoaming effect, strong defoaming power, less dosage, stable chemical properties, good heat resistance and oxidation resistance, and has extremely high ecological and economic benefits.

Description

Technical field: [0001] The invention discloses a preparation method and application of a novel defoamer, belonging to the technical field of application of dyeing auxiliaries. Background technique: [0002] In the process of processing textiles, various dyes and auxiliaries are often added to assist in the processing. The range of additives involved is very large. For example, the additives added to the sizing slurry include penetrating agents, softeners, wetting agents, defoamers, emulsifiers, etc. Most of these additives belong to surfactants. After mechanical vibration, it is easy to generate foam. When processing fabrics, the existence of foam will reduce the contact surface between liquid and fabric, and uneven processing will occur, which will greatly affect the quality of products and the production process, and bring many difficulties and even dangers to production. Therefore, it is necessary to eliminate these harmful foams. attracted more and more people's atten...
