Defoaming agent for spinning

Abstract

The invention belongs to the technical field of textiles. The invention particularly relates to a defoaming agent for spinning. The defoaming agent comprises the following components in parts by weight: 10-20 parts of polydimethylsiloxane, 30-50 parts of hydroxyl-terminated polydimethylsiloxane, 15-35 parts of polyoxyethylene stearate, 25-40 parts of glyceryl monostearate, 0.1-0.5 part of hydroxyethyl cellulose, 5-20 parts of sodium p-styrenesulfonate and 1-5 parts of polysiloxane. The defoaming agent has the beneficial effects that the defoaming rate of methyl silicone oil under a high-temperature condition is increased to a certain extent, and meanwhile, the pore structure of the cellulose is beneficial to converting large foam into small foam, so that the defoaming effect of the defoaming agent is enhanced, the efficiency is improved, and the application prospect is wide.

Description

technical field [0001] The invention belongs to the technical field of textiles, in particular to a defoamer for textiles. Background technique [0002] There are nearly 100 categories of textile printing and dyeing auxiliaries in the world, about 15,000 varieties, with an annual output of 2.8 million tons and a market sales of more than 16 billion US dollars. my country's printing and dyeing industry has developed rapidly in recent years. Although there are still many problems in my country's textile printing and dyeing auxiliaries due to historical reasons, the textile industry is an important livelihood industry in my country. Textile printing and dyeing auxiliaries have broad prospects and great development potential. [0003] However, these auxiliaries used in large quantities in the textile printing and dyeing industry, such as surfactants such as penetrating agents, refining agents, leveling agents, dispersants, and color fixing agents, cause air to enter due to stirr...

Problems solved by technology

[0003] However, these auxiliaries used in large quantities in the textile printing and dyeing industry, such as surfactants such as penetrating agents, refining agents, leveling agents, dispersants, and color fixing agents, cause air to enter due to stirring, transmission, and liquid material transportation, thereby generating a large amount of Foam, which in turn causes various failures, has a negative effect on the dyeing quality and seriously affects the quality of the product
