The Strength of Hemp Bast Fiber: From Plant to Product

Hemp bast fiber is the stronger longer fiber produced within the hemp stalk. The hemp plant produces two types of fiber: hemp hurd fiber and hemp bast fiber.

The hurd fiber is what’s used in many non-woven applications such as hempcrete, animal bedding, garden mulch and other applications.

In this post I will share a little bit about the strength, durability, versatility and sustainability of hemp bast fiber.

The Craft of Bast Hemp Fiber Production

Fibers, particularly bast hemp fiber, combine historic traditions with new advances from plant to product.

For millennia, this cannabis sativa-derived material has been used in textiles, paper, and building materials.

The art and science of turning raw hemp into usable fiber require meticulous attention at each step to assure quality and sustainability.

What is Hemp Bast Fiber?

The origin of bast hemp fiber is the outer bark of the hemp stalk.

Growing hemp in different climates and soils makes it a versatile and often easier crop to grow than other popular bast fiber crops.

It shows its resilience and thankfully requires zero or very low pesticide use.

It might not be the easiest crop to harvest and process however.

Most farmers can grow hemp for bast fiber production with a little education, and the right equipment.

When to harvest Hemp Bast Fiber?

For fiber, hemp is harvested earlier than if being grown for seeds or Cannabinoid production, like CBD.

Long, robust, and supple fibers are appropriate for subsequent processing with this scheduling. In other words when growing for seed or cannabinoid production you want the plants to fully mature before harvesting.

Whereas when growing for bast fiber you want to harvest after about 110 – 120 days before the stalks get too bulky and the fibers harden.

Retting hemp stalks after harvest is crucial but often overlooked in bast hemp fiber production.

Retting naturally breaks down the pectin, keeping hemp fibers together and separating them from the woody core.

Field retting leaves stalks on the ground to be broken down by dew, rain, and microbes; water retting submerges them in water to speed up the process; and chemical retting employs substances to speed up the process.

Each process has varied effects on fiber quality and texture.

After retting, stalks are malleable and ready for decortication, which separates bast fibers from hurd.

Decorticating stalks by striping them apart and removing the fiber is traditional.

Modern hemp processing technologies minimize waste and process huge volumes efficiently.

Decortication quality influences fiber purity and usage, making it crucial.

Combing or carding the fibers aligns them and removes debris and hurd fibers during processing.

The eventual usage of hemp fiber depends on this stage; finer, longer fibers are used in textiles, while shorter, coarser fibers are used in industry.

The transformation of raw, retted hemp into clean, straight strands is a marvel of human ingenuity and natural processes.

After refining, hemp fibers are spun into yarns or threads.

The spinning process ranges from millennia-old hand-spinning to high-speed, automated equipment.

Finer threads are spun for high-quality fabrics, and coarser threads are spun for hemp rope or industrial materials.

The final phases in bast hemp fiber production are dyeing and finishing.

Hemp textiles are dyed using natural colors and eco-friendly procedures to match the sustainability of hemp fiber production.

Finishing treatments can improve fabric softness, durability, and water and stain resistance.

This phase’s decisions can considerably impact the product’s environmental footprint and performance.

From cultivation to finishing, each step in creating bast hemp fiber contributes to the fiber’s distinctive properties.

As consumers and industry become more environmentally conscious and seek sustainable alternatives, bast hemp fiber will be a natural choice.

The careful transformation of this old plant into modern marvels shows humanity’s respectful, innovative, and sustainable relationship with nature.

Other Common Questions About Hemp Bast Fiber

Is hemp a bast fiber?

Yes. Hemp stalks are considered a bast fiber producing plant.

The hemp plant produces two types of fiber: hurd and bast. bast fiber is the long strong fiber used for woven applications such as ropes, yarn, twine, fabrics and webbing.

how to turm hemp bast fiber into fabric

We actually have an entire post about this very topic, so I suggest you check that out here.

But the basic process is as follows:

Harvesting: Hemp plants are harvested for their stalks, where the bast fibers are located, typically when they reach maturity, about 3-4 months after planting.
Retting: The harvested stalks undergo retting, a process that helps separate the bast fibers from the inner woody core (hurd) through controlled rotting. This can be done through field retting (leaving the stalks in the field to be exposed to dew, rain, and bacteria) or water retting (submerging the stalks in water).
Drying: After retting, the stalks are dried to reduce moisture content.
Decortication: The dry stalks are then processed through decortication, where mechanical action breaks the stalks and separates the bast fibers from the hurd.
Scutching: This step involves beating the separated bast fibers to remove any remaining hurd particles and to begin separating the fiber bundles into individual fibers.
Hackling: The fibers are combed through a series of hackles (combs of increasing fineness) to fully separate the fibers and to align them, making them straight and suitable for spinning.
Spinning: The aligned hemp fibers are spun into yarn, using traditional spinning techniques similar to those used for other natural fibers like cotton or flax.
Weaving/Knitting: The hemp yarn is then woven or knitted into fabric using looms or knitting machines, following patterns and techniques that vary depending on the desired fabric type and texture.
Finishing: The woven or knitted fabric undergoes various finishing processes, which may include washing, bleaching, dyeing, softening, and drying, to enhance the fabric’s appearance, texture, and performance characteristics.
