Human-made Eco-friendly Fiber: Find a Better Way to Sustain

Human-made Eco-friendly Fiber: Find a Better Way to Sustain

 

Globally the trend is to go back to nature and patronize the natural product. Green marketing is the most commonly seen in affluent post-industrial societies. Consumers are also much more aware and conscious of what they buy & its real impact.

Synthetic polymers depend upon the resources of oil, gases for their monomer source. These resources take millions of years to regenerate. Also, most of the synthetic polymers are not biodegradable. Regular uses of these resources have created a problem of an energy crisis and environmental pollution. 

So, various efforts have been done to make synthetic polymers ecofriendly. Many kinds of research have been conducted to make the polymers biodegradable.

Biodegradable polymers are those which are completely converted by microorganism to carbon dioxide, water or methane. Attention is focused on synthetic fibers which are based on natural renewable resources. 

 

PLA (Polylactic Acid)

 

PLA belongs to the family of Poly (α hydroxy). It is a biodegradable natural polymer which has wide applications in textiles. The monomer used for the manufacturing PLA is obtained from renewable crops.

PLA not only as a product is biodegradable, it’s raw materials available in nature in the form of corn, sugar beets, wheat, and other starch-rich products are also biodegradable.

It can be processed like other thermoplastic materials to filament or can be molded or blown to produce different plastic products. Since it is biodegradable and can be processed to different products with a variety of properties, it can be used for a wide range of uses from packaging to surgical sutures.

PLA is one of the major substitutes for existing synthetic non-degradable fibers. Source for PLA polymer is corn which is renewable and cheap. Its excellent features may lead to increased demand in the future. 

 

Lyocell

 

Lyocell is a form of human-made fiber that consists of cellulose fiber made from dissolving pulp using a solvent spinning process. It was developed in 1972 by a team at the now-defunct American Enka fibers. "Lyo" comes from the Greek "Lyein", which means to dissolve, "cell" is taken from "Cellulose", the two together are called "Lyocell."

The primary raw material for Lyocell is the cellulose from wood pulp (gotten from managed tree farms) which is chemically broken down in a soupy sludge which is then pumped out through reformed into more easily woven fibers. Thus, Lyocell can be accurately referred to as a recovered or regenerated fiber. The production of Lyocell produces no harmful byproducts.

Lyocell fabric is highly anti-pilling and very resistant to wrinkles. It has a smooth and comfortable feel of cotton fiber and has more excellent moisture absorption than cotton and natural breathability.
