Description

Oil removing agent for continuously processing polyester/ammonia and nylon/ammonia blended knitted fabric and preparation method thereof
Technical Field
The invention relates to a degreasing agent for continuous processing of textile printing and dyeing open width and a preparation method thereof, in particular to a degreasing agent for continuous processing of polyester/ammonia and nylon/ammonia blended knitted fabrics and a preparation method thereof.
Background
Because of the excellent serviceability of the spandex fiber, the application of the spandex fiber in the chemical fiber blended fabric is continuously expanded, and the content of the spandex fiber is continuously increased from the initial 2-5% to 30-50%. In the weaving process of the fabric, besides various textile oil agents such as mineral oil and knitting oil, the spandex also contains a large amount of organosilicon lubricants. The presence of these oils necessitates removal before the dyeing process, which otherwise leads to various dyeing problems such as color unevenness and mottling.
Compared with intermittent rope-shaped processing, the open-width continuous pretreatment can obviously improve the processing quality: the abrasion and wrinkle are reduced, the fuzzing is not easy to occur, and the surface of the fabric is cleaner; meanwhile, the production efficiency is higher, and the energy consumption can be reduced by about half. Thus, open-width continuous processing has become a trend in the industry. However, compared with the in-cylinder oil removal, the continuous oil removal water washing has the problems that the contact time of liquid distribution is short, the oil removal is not easy to be sufficient, and simultaneously, due to the continuous accumulation of impurities, the oil removal water washing is easy to be reversely stained in the later period of treatment, so that the head and the tail are poor, and the quality is not uniform.
Most of the degreasers commonly used in the market at present are developed on the basis of a processing technology in a rope-shaped cylinder with low spandex content, and cannot completely meet the requirement of open-width continuous oil removal. Firstly, the surface tension of textile oil such as mineral oil, knitting oil and the like is about 30mN/m generally, and the surface tension of organosilicon lubricant for spandex spinning is about 20mN/m generally; the surface tension of the traditional deoiling is generally lower than 30mN/m, and the requirement of deoiling on spandex yarns cannot be met. Thirdly, the problem of continuous accumulation of oil agents does not exist in oil removal in the cylinder, the oil agents are continuously increased along with the passage of time in continuous treatment, the anti-sticking problem is serious, and the oil removal agents are required to have stronger emulsifying and dispersing capacity; finally, the contact time of the open-width continuous processing cloth liquid is short, the penetrating power of the degreaser is required to be better, and the degreasing efficiency is required to be higher.
The degreasing agent is urgently needed in the field, can meet the degreasing requirement of high-content spandex blended fabric, meets the requirements of high permeability and high emulsifying and dispersing power of open-width continuous pretreatment, and meets the development requirement of the market industry; meanwhile, the environment-friendly material does not contain APEO, NPEO and other non-environment-friendly components.
Disclosure of Invention
The invention solves various pretreatment problems caused by insufficient permeability, insufficient emulsifying and dispersing force and insufficient removing force of the silicone oil agent for spinning in the open-width continuous pretreatment process of the traditional degreaser, meets the requirements of dyeing and finishing processing at the later stage, and achieves the aims of improving efficiency, saving energy and reducing emission.
The invention provides a degreasing agent for continuously processing polyester/ammonia and nylon/ammonia blended knitted fabrics, which comprises the following components:
