Low-temperature plasma pre-treatment process

Abstract

The invention relates to a low-temperature plasma pre-treatment process which is characterized by comprising the following steps: sorting wool; washing wool; drying; carrying out low-temperature plasma treatment; sizing and the like. The invention is the low-temperature plasma pre-treatment process which is clean and uniform to treat and has water-saving and energy-saving effects, and the surface hydrophilic performance of spinnable blanket wool (yak hair, wool, camel hair and the like) is effectively improved, so that the dyeing property of the wool is improved, and the dyeing, coating and bonding performances are improved.

Description

technical field [0001] The invention relates to the field of textile printing and dyeing, in particular to a low-temperature plasma pretreatment process. Background technique [0002] Plasma refers to a gas that is fully or partially ionized, and gaseous substances produce different degrees of separation of molecules and electrons under the action of energy such as heat and electricity, forming negatively charged electrons and positively charged ions, etc. A mixed gas containing atoms, molecules, electrons, ions, photons, various metastable and excited state particles is called plasma. Plasma is roughly classified into high-temperature plasma and low-temperature plasma. When the electron temperature is very high and the gas temperature is close to normal temperature, the plasma is in a state of thermal imbalance, which is called low-temperature plasma. Traditional dyeing uses water as the medium, the dyeing time is longer, the dyeing temperature is higher, the energy con...

Problems solved by technology

Generally, after the dyeing is finished, the dye in the dyeing residue is not exhausted, or the floating color of the dyed fabric is washed in the post-treatment, which will cause serious water pollution.
