ABSTRACT

In recent years, many researches are the target of environment friendly. The digital inkjet printing

gradually attention, the requirement are less dyes, producing a few wastewater. PLA has biodegradable

performance can be decomposed in the soil, the environmental burden small. Chitosan is a

biodegradable polymer, it comes from natural shrimp and crab shell produced when a raw material, it

has a non-toxic, Biodegradable. In the first, the pre-treatment of chitosan ,and then inkjet printing on

pre-treatment of PLA , to explore the effects of processing conditions. The result show pre-treatment

concentration 5 wt%,pre-treatment concentration curing temperature of 150 , paste pH value of 3,

steaming time at 50 min have the best K/S.

Keywords: inject printing, Chitosan, reactive dye
