Eco-friendly dyeing of jute packaging fabrics was evaluated using aqueous extraction of factory tea ( wastes. Jute and factory tea wastes are available in Bangladesh and jute bags are used for packaging of various exportable agricultural commodities. The extract of factory tea waste (FTW) is dark coffee colored and it was characterized by attenuated total reflection-fourier transform infrared (ATR-FTIR) and microbial analysis. Nontoxic, non-allergic and eco-friendly natural dyeing process of jute packaging fabrics using extract of FTW were developed and optimized. Metal mordants 10 % on the weight of fabric was used to get the fastness properties of dyed jute fabric. The methods of application of mordants were pre-mordanting, simultaneous or meta-mordanting and post-mordanting. The color fastness and tensile properties were measured for all jute packaging fabrics and it is found that the dyed jute packaging fabrics showed a slight decrease in tensile breaking force (N) than undyed jute packaging fabric. The highest color fastness obtained with the meta mordanting method with ferrous sulfate mordant in a shade of dark coffee. The results of the color fastness for light and washing showed an excellent value of grade 4-5.

Food packaging industries generally use petroleum-based packaging materials that are non-biodegradable and harmful to the environment. Eco-friendly polymers such as chitosan (CH), gelatin (GE), and cellulose nanocrystals (CNCs) are leading viable alternatives to plastics traditionally used in packaging because of their higher functionality and biodegradability. In this study, an innovative approach has been disclosed to prepare new packaging materials by utilizing chitosan, gelatin, and cellulose nanocrystals (CNCs) through a simple solution casting method.

The present work investigates the phase morphology and properties of biodegradable thermoplastic starch (TPS)-poly(lactic acid) (PLA) blends and their jute fiber (JF) biocomposites. The TPS/PLA blends and TPS/PLA/JF composites were fabricated using a twin-screw extruder and then injection molded into the test specimens, varying the TPS/PLA weight fractions (80/20, 60/40, 40/60, and 20/80) while keeping the JF content constant (10 wt%). At 80 wt% TPS, the TPS/PLA blend showed a co-continuous structure, whereas the remaining blends (20, 40, and 60 wt% TPS) exhibited a TPS droplets-PLA matrix structure.

Eco-friendly materials must replace pure synthetic materials to protect the environment and improve human welfare. This study uses a blow room-integrated carding machine to create a filmy web by properly mixing modified jute and polyester fibers. Jute-polyester fiber blended carded webs have been utilized to produce jute-based hybrid nonwoven fabrics (JHNFs), which are subsequently given an antibacterial treatment by spraying a solution of silver nitrate, ethanol, and ammonia.

Background: Jute fiber is one of the most versatile natural fibers that is widely used as a raw material for packaging, textiles, and construction; and as a reinforcement in composite materials for heavy-duty applications. In the past, acid hydrolysis and mechanical treatment via the ball milling method were common in the extraction of cellulose nanofiber (CNFs) from natural plant fibers. However, there are some drawbacks of using those methods where there will be a huge quantity of acidic wastewater generated when the acid hydrolysis method is performed.
