Description
Technical field
The present invention relates to super (Asia) the critical CO of one kind2Scouring of wool method belongs to hair (suede) fiber scouring of wool field.
Background technique
The purpose of scouring of wool is dust, wool perspiration, dirt, the grease etc. removed on wool, is obtained without entanglement or felting phenomenon
Scoured wool.Scoured wool is the basis of wool spinning product, and the quality of scouring of wool quality has a significant impact the processing of rear road.Sheep was growing
Cheng Zhong, on the one hand due to the influence of feeding environment, rich in mineral and smoits on wool, such as sand, various herbaceous stems, feeding
Material etc..On the other hand, sweat, rouge, scurf, the excrement etc. that sheep excretes during the growth process are accompanied by wool.Scoured wool table
Face amounts of residual contamination content affects scoured wool whiteness, dyeability and drawing-off and spins performance；Scoured wool shatter value and injury tolerance shadow
Ring the combing, spinning, weaving performance of scoured wool.Therefore, status and effect of the scouring of wool technology in wool spinning production are particularly significant.
Traditional scouring of wool method is broadly divided into two methods of aqueous medium scouring of wool and solvent scouring by the difference of scouring of wool medium.Water is situated between
Matter scouring of wool is the effect by surfactant and inorganic salts, so that lanolin is emulsified and is separated from fiber, reaches grease removal
Purpose, it usually needs it is completed under higher temperature and stronger mechanism, general 1t wool needs to consume the water of 15~40t, by
4 × 10 are up in containing organic pollutants, the waste water from washing wool COD values such as lanolin and wool perspiration4~6 × 104Mg/L, lanolin recycling
It is difficult.Though solvent method scouring of wool can effectively recycle lanolin, the device is complicated, and investment cost is high, only several overseas enterprises
Using application is less.
As environmental problem is got worse, explores environmental-friendly cleaning scouring of wool method and have become current research tendency.Benefit
Use CO2Fluid is to clean the processing such as medium progress fibrous material dyeing, modification at home and abroad to achieve stage Journal of Sex Research
Progress.Compared with aqueous medium dyeing course, CO2Nontoxic, nonflammable, cheap, Zero-discharge non-pollution, and there is high dissolution
Property with diffusivity feature, show preferable application prospect in terms of hair (suede) fiber cleaning.
Summary of the invention
