The present invention relates to the field of textiles. More specifically, it pertains to a process for producing and using fibrillated biodegradable microfibers.

The process involves sourcing and preliminary processing plant materials encompassing cellulose-rich fibers followed by mechanical compression method or a solar powered electric presser to expel surplus moisture. Then, an aqueous immersion technique is employed for thermal processing to obtain thermal processed plant materials. The thermal processed plant materials then undergo a rinsing step and a mechanical disintegration step to reduce the thermal processed plant materials into micro-sized entities while maintaining the integrity of the fibers. Furthermore, matrix forming substances, stabilizer, sealant and preservative to said micro-sized entities subsequently undergoing a blending process to obtain a first mixture. Lastly, the first mixture is exposed to a controlled desiccation regimen followed by implementing a mechanical reduction process resulting in the attainment of said fibrillated biodegradable microfibers with a diameter measurement below the threshold of 10 ?m.

A method for producing shortened anionically modified cellulose fibers having an average fiber length of 1 ?m or more and 500 ?m or less, the method including cleaving sugar chains of anionically modified cellulose fibers by thermal decomposition under temperature conditions of 50? C. or higher and 230? C. or lower, wherein the average fiber length of the anionically modified cellulose fibers is 700 ?m or more and 10000 ?m or less.
