You will have heard of lyocell material, or seen it on a clothes tag, however what precisely is it? And is it sustainable? Effectively, compared to polyester it’s.

Many of the garments we put on right now are produced from polyester, aka plastic. Polyester is produced from non-renewable petroleum (crude oil) that’s extracted from the earth unsustainably.

To create polyester, 70 million barrels of oil are used yearly, and turning this oil into polyester material releases plenty of toxins into the surroundings.

On prime of this, each time polyester items are washed, they shed microplastics into our waterways. An estimated 496,030 polyester microfibers are launched from a 6kg wash – however this could fluctuate primarily based on a number of elements.

Lately, a brand new research discovered we could possibly be ingesting 11,000 microplastics per yr. Microplastics have been present in our lungs, feces, and even our placentas. Whereas the well being results of this are nonetheless unknown, it could’t be good.

A great way to cut back microplastic publicity is to change to extra pure fibers in our clothes. Lyocell is a well-liked new material being touted by sustainable manufacturers. Right here’s what it’s essential find out about lyocell material and which manufacturers are utilizing it.

What’s Lyocell Fabric? And Is It Really Sustainable?

is lyocell synthetic or natural?

Lyocell is a semi-synthetic fiber that’s made primarily from wooden cellulose, often from eucalyptus timber. It’s generally used as an alternative choice to cotton or silk.

Lyocell was initially developed by American Enka in 1972, however solely just lately did it achieve recognition within the 20^th century. With American Enka, lyocell material solely made it by way of the pilot section of growth earlier than it was deserted.

It wasn’t till the Eighties when a British firm known as Courtaulds Fibres created a brand new material known as Tencel primarily based on lyocell analysis. The phrases Tencel and lyocell can be utilized interchangeably now as a result of they’re chemically similar.

Its manufacturing course of does contain some artificial chemical substances, however they’re recycled through the circuit and so they don’t generate by-products.

how is lyocell made?

Wooden is damaged down into chips and loaded right into a vat of chemical digesters. This softens them into pulp.
This pulp is washed in water and could also be bleached to sanitize it. Subsequent, it’s dried in a sheet, and rolled into spools.
These sheets are then damaged into squares and positioned in pressurized and heated vats of amine oxide.
As soon as the cellulose has dissolved into a transparent liquid, it’s filtered and pumped by way of spinnerets.
Because it goes by way of the spinnerets, cellulose is become lengthy, skinny fibers.
The ensuing fibers are immersed in a vat of diluted amine oxide to set, and they’re then washed with demineralized water.
The lyocell fibers are then dried, and a lubricant, similar to silicone or cleaning soap, is added.
Subsequent they’re carded, which seperates and orders the strands.
Lastly, the fibers are reduce and they’re then able to be become an array of merchandise.

is lyocell a great material?

Lyocell is an efficient material when it comes to substituting it rather than cotton or silk. It’s clean fibers are a superb alternative for individuals with delicate pores and skin and it’s mushy to the contact. It’s additionally extra immune to pilling than cotton.

By way of the surroundings, lyocell is an efficient material compared to typical cotton and polyester. The manufacturing course of makes use of much less water and vitality than various materials, like cotton.

One of many important producers of lyocel is TENCEL™ Lyocell: Their fibers are produced in a closed loop course of which recovers water and 99.8% of the solvent, which transforms wooden pulp into cellulosic fibers with excessive useful resource effectivity and low environmental affect.

Moreover, TENCEL™ lyocell is biodegradable and compostable, if it’s not mixed with any polyester, elastane or nylon materials/components.

Nevertheless, you have to be aware that not all lyocell is produced from the identical supplies. Most lyocell is produced from eucalyptus timber, whereas others are produced from bamboo, oak, birch, or different forms of wooden.

Eucalyptus and bamboo are nice selections, as they develop quick, require minimal inputs, and sequester carbon as they develop. Moreover, not like typical cotton, eucalyptus and bamboo don’t require irrigation or pesticides.

If you happen to can, search for lyocell produced from wooden sourced from responsibly managed forests, just like the Forest Stewardship Council (FSC) certification.

is lyocell higher than cotton?

Lyocell is healthier than cotton when it comes to water, land and pesticide utilization.

Cotton is a water-intensive crop. However chemical substances sprayed on the plant will combine with water runoff. This results in groundwater contamination. To provide you an thought of how water-hungry cotton is, it takes 2,500 liters of water to provide one t-shirt.

Cotton can also be one of many prime 4 genetically modified crops on the planet. It’s thought-about the world’s “dirtiest crop” as a result of it requires heavy quantities of poisonous pesticides. These pesticides have poisoned hundreds of cotton farmers, in addition to pollute the surroundings.

On prime of this, cotton wants greater than 5 occasions the land that eucalyptus timber. That’s plenty of house that could possibly be utilized in different, much less water-intensive methods.

This being mentioned, in case you personal any cotton clothes, don’t toss them out in favor of changing them with lyocell merchandise. Essentially the most sustainable factor you are able to do is use what you have got (and at that time, the assets have already been used up).

If you happen to’re serious about getting a brand new merchandise, select to help manufacturers that make the most of lyocell over typical cotton. Nevertheless, selecting natural cotton over typical cotton can also be a significantly better alternative, because it’s grown with out pesticides and with much less water.

Modal can also be one other material you must think about using, as it’s just like lyocell. Right here’s every part it’s essential find out about modal material and the way it’s sustainable.

which manufacturers use lyocell material?

A number of manufacturers have began to see the potential in lyocell material. Listed below are the highest sustainable manufacturers which are using the material.
