Modal Knit Fabric
What is Modal Fabric
Modal fabric is a semi-synthetic textile. It comes from the cellulose of beech trees. Manufacturers get cellulose from hardwood trees like birch and oak. They use chemicals to turn it into fibers. The process uses sodium hydroxide and carbon disulfide. These chemicals are used in lower amounts than in viscose. This means modal rayon makes less toxic waste. It also needs fewer chemical steps. Modal does not have the aging step that viscose rayon has. This makes it faster and better for the environment. The cellulose in modal fabric is changed by chemicals. So, it is not fully organic. But it is still better for the planet than some other semi-synthetic fabrics. Lyocell is another rayon type. It uses a closed-loop process. Lyocell does not change the cellulose with chemicals. This makes lyocell even more eco-friendly. Modal knit fabric is special because of its chemical makeup. It is an improved kind of rayon.
Note: Modal fabric is part of the rayon family. It is softer, stronger, and better for the environment than viscose rayon.
Key Features
Modal knit fabric has many good qualities:
Softness: Modal fabric feels smooth and gentle on your skin. Labs use machines like the M293 FTT fabric touch tester to check softness. These tests look at bending, friction, and thickness. In blindfolded tests, people say modal knit fabric is softer than cotton and polyester.
Breathability: Modal fabric lets air pass through easily. This keeps you cool in warm weather or when you are active.
Stretch: Modal knit fabric stretches well because of its looped yarns. This helps you move freely and feel comfortable.
Durability: Modal rayon does not pill much and lasts through many washes. Tests like the Martindale abrasion test show modal fabric is strong. Polyester is even stronger, but modal is still tough.
Moisture Control: Modal fabric soaks up moisture better than cotton. This helps you stay dry and comfy.
Eco-Friendliness: Modal uses fewer harsh chemicals than viscose rayon. It also makes less waste. The way it is made is better for the planet than many other semi-synthetic fabrics.
Types of Modal Knit
There are different types of modal knit fabric. Each type has its own features and best uses. The table below shows the main types and how they are different:
Type of Modal Fabric | Key Properties and Differences | Common Uses |
|---|---|---|
Regular Modal | Soft, breathable, durable, does not pill easily | General clothing |
MicroModal | Made with finer yarn; softer, lighter, more breathable, does not pill easily | Luxury clothes, light wear |
Modal-Cotton Blend | Soft and breathable like modal, strong and useful like cotton | T-shirts, dresses, underwear |
Modal-Spandex Blend | Stretchy and wicks moisture, stays soft | Sportswear, activewear |
Modal-Polyester Blend | Soft and wicks moisture, strong and resists wrinkles | Dresses, blouses, jackets |
Modal Air and MicroModal | Lighter versions made by Lenzing AG, extra soft and breathable | Light, premium modal fabrics |
Modal knit fabric is often made with jersey knit. This gives it stretch, a nice drape, and helps it keep its shape. Each type’s features depend on the blend and how it is knit. MicroModal is even softer and lighter than regular modal. Blends with spandex add more stretch for sportswear.
Tip: If you want a fabric that is soft, stretches, and keeps its shape, modal knit fabric is a smart pick for clothes and home items.
How is Modal Fabric Made
Beechwood Pulp Process
To make modal fabric, you start with beech trees. These trees grow in special forests that are managed well. Beech trees use less water than cotton. This helps save water. They spread on their own, so you do not need to plant them often. You also do not need to water them much. This makes modal rayon better for the planet than cotton. Workers cut down the trees and chop the wood into small pieces. Next, they get cellulose from the wood pulp. Cellulose is the main part needed for modal rayon.
Note: Getting wood from certified forests helps protect animals and plants. It also helps people who live near the forests. This keeps nature healthy.
Making modal fabric uses fewer chemicals than viscose rayon. But it still needs chemicals like sodium hydroxide and carbon disulfide. These chemicals can hurt the environment if not handled right. Some companies use closed-loop systems to reuse chemicals and stop pollution. If you buy modal fabric with certifications like FSC, you help the planet.
Fiber Production
After getting cellulose, the next step starts. The cellulose is mixed with chemicals. Sodium hydroxide breaks down the pulp. Carbon disulfide changes the cellulose into a thick liquid. This liquid is called viscose. The viscose is pushed through tiny holes in a spinneret. This makes long, thin fibers. The fibers are then put in a bath of sulfuric acid to make them solid.
Chemicals used to make modal fabric are:
Sodium hydroxide (caustic soda)
Carbon disulfide
Sulfuric acid
These chemicals can be dangerous to people and nature. Carbon disulfide is very toxic and can hurt workers if not used safely. Closed-loop systems catch and reuse these chemicals. This makes the process safer and cleaner. Companies like Lenzing use these systems to keep workers and nature safe. Modal rayon with OEKO-TEX or GOTS labels has very little chemical left in it.
Washing new modal clothes before wearing them helps remove leftover chemicals.
The fibers are spun into yarn. This yarn is used to make modal rayon fabric. The process makes fibers that are strong, soft, and soak up water well. Modal rayon can break down in nature, but it may take a long time at home because of the chemicals.
Knit Construction
The modal yarn is knitted to make fabric. Knitting gives modal rayon its stretch, softness, and lets air pass through. Most modal knit fabric uses jersey knit. Some use rib knit or other patterns. The way the yarn is knitted changes how the fabric feels and works.
The knit and how tight it is affects:
How much water it soaks up
How much air can pass through
How long it lasts
How much it pills
A tighter knit soaks up more water but lets less air in. Rib knit modal rayon does not shrink or pill much. Air-jet spun yarn in rib knit modal fabric soaks up water well and does not pill. This makes it good for underwear and lingerie. The way the yarn is spun and knitted changes how the fabric feels and how long it lasts.
Knit Construction Aspect | Effect on Modal Fabric Properties |
|---|---|
Denser knit | Soaks up more water, lets in less air |
Shrinks less, keeps its shape better | |
Air-jet spun yarn | Pills less, soaks up more water |
Makes wider fabric, shrinks more in width | |
Double lacoste structure | Pills the least, shrinks less in length |
Tip: How you knit modal yarn changes how your clothes feel and last. Pick modal knit fabric for comfort and strength.
When you ask how modal fabric is made, every step is important. From beech trees to the final knit, each part changes the fabric’s quality and how it affects the earth. Modal rayon is special because it uses good trees, careful chemical use, and smart knitting.
