Hair treated with a formulation containing both cationic HEC and high molecular weight PEO showed30%better wet combing reduction than the formulation containing cationic HEC only.

Meanwhile,the effects of cationic cellulose as wet end chemicals on the strengthening and the sizing of different recycled pulps were discussed in detail.

The antibacterial monomer(ETA) was grafted on the cellulose to prepare the cationic cellulose,used NaOH/thiourea aqueous solution as solvent to melt the cationic cellulose in the frost condition,then formed membrane by coagulating with CaCl2/HCl aqueous solution,finally prepared the new type covalent touch antibacterial membrane.

In this paper we have synthesised several cationic cellulose with different degrees of substitution(DS).

The rheological properties of cationic cellulose ether(JR-30M) in aqueous solution were studied and the effects of concentration(ρJR),temperature,pH value and additive salt were discussed.

A kind of cationic hemicelluloses was synthesized by means of quaternization,using sugarcane bagasse hemicelluloses as the raw material,reacting with cationic reagent in alkaline condition.
