With the ever-growing interest in sustainable textiles within the fashion industry, many eco-friendly alternatives have sprung up. From organic cotton to bamboo and hemp fabric, designers are prioritizing eco-consciousness. Hemp fabric joins the club and is becoming more popular in apparel making.
Additionally, hemp is popular for many qualities. These include its usefulness, versatility, and durability. Hemp is one of the oldest textile fibers2. Are you Looking to understand this versatile fiber that brands are turning to fabric? This article provides a holistic look at hemp textiles.
Quick links for Hemp Fabric:
Hemp fabric or textile comes from the stalks of the Cannabis Sativa plant. The cannabis Sativa plant is the same plant that produces marijuana and its derivatives. However, farmers breed this plant for various purposes.
Of course, the most well-known category is breeding tetrahydrocannabinol (THC), the chemical that produces a stoned high. This is the primary psychoactive chemical in cannabis and the active ingredient in recreational marijuana.
On the other hand, the breed of cannabis Sativa fiber for eco-friendly clothes contains low THC. The cultivators of such plants deliberately reduce the levels of the psychoactive cannabinoid their crops produce.
The process of cultivating this breed leads to producing stronger fibers for fabric and clothing. This resulting fabric is often called industrial hemp.
Hemp fiber, a renewable resource, has many qualities and benefits that make it versatile. This fiber serves various purposes, from paper and canvas to clothing, ropes, and hemp blankets. More and more sustainable clothing brands are now using hemp fabric to make clothes.
People regard this fabric as one of the most sustainable fabrics. Hemp grows fast, and therefore it requires fewer resources. The hemp crop requires little water to grow from farming and cultivating. Also, the cultivation of organic hemp fabric replenishes soil nutrients which helps to improve soil health.
The process of producing hemp fabric can be a labor-intensive method. The fast-growing hemp plant goes through the following processes to become the fabric for clothes:
People have been cultivating hemp for thousands of years. The pattern of hemp cultivation for hemp seed is different from cultivating hemp for fiber. The farmers sow the seeds close together for fiber use at around 300,000 plants per acre. For seeds, this is only about 150,000 plants per acre.
Farmers harvest the plant during the early to mid-flowering stage. They use a special machine to harvest most plants that they grow for hemp fabric.
Many traditional farmers in the United Kingdom believe that male hemp plants produce finer and silkier fiber compared to female hemp plants. In support of this, a study revealed that the female fiber is a bit stronger while the male fiber is finer.
After the farmers cut the plant, they place the stem on the ground for several weeks. The purpose of this is to allow retting to occur. This is a decay method whereby the pectin, which binds the hemp fiber, decomposes. Alternatively, retting also occurs in water tanks to speed up the action of decay. Sometimes producers use additives and enzymes to speed up the procedure.
Decortication occurs either when the stems are wet from retting or after being dried. Decorticating hemp fiber means removing the central woody core from the stem's outer layer.
When the stems are wet, remove the damp fibers from the core. Then, you dry them. On the other hand, you can dry the stems and run them through a specialized machine. This separates the woody core from the fibers.
The farmers then form the fibers into bales after separating them from the woody core. Afterward, they remove the fibers from the field to take them for processing into yarn. Producers now implement chemical or mechanical processes to make the fibers softer and boost elasticity. Alternatively, some producers just spin the fiber without processing it further.
Removing lignin from hemp fiber is necessary to ensure soft hemp textiles' production. Lignin is an organic polymer that forms a major part of the wood and makes plants woody. This component adds stiffness and compressive strength to a plant cell wall.
Lignin is also responsible for traditional hemp fiber's scratchy and rough texture. This makes the hemp fabric strong and tough to feel. Producers remove the lignin to provide a softer and smoother hemp fabric feel. The resulting hemp fabrics produce skin-friendly hemp clothing.
Machines spin and twist the fibers together to form long threads which are woven into textiles. At this stage, blending can occur whereby other fibers are added and mixed with the hemp prior to turning them into hemp garments. Traditionally, producers used a hand-spinning method to achieve this. They used two tools which are the distaff and drop spindle.
People have grown the crop and used hemp fiber for thousands of years. Cannabis can be traced to the steppes in Central Asia and was initially cultivated in China. At first, people in India and China made use of this plant for human and animal food.
Over time, they discovered the qualities of hemp fiber for making non-food items. In 2000 BC, the people of China considered hemp one of the sacred crops. This was due to its discovered importance and versatility. Its uses included producing building materials, garments, medicine, and paper.
Around 500 to 1000 AD, hemp made its entrance to Europe. At that time, hemp was primarily used to produce paper. It was also used to print Bibles. The popularity of hemp began to spread around the world.
The commencement of the 20th century served as a critical point in the account of hemp. In Utah, in 1915, the government outlawed the use of hemp. The reason was largely due to the known history of the uses of this plant as marijuana. The prejudice against immigrants from Mexico also contributed to this.
The US government had not recognized that hemp or cannabis Sativa had species that have a small amount of tetrahydrocannabinol (THC) and useful breeds not cultivated as a drug for marijuana.
Just before the hearings to outlaw this plant, the American Medical Association (AMA) came out to testify. They had realized that the cannabis plant the government was planning to outlaw was important in the medical field.
Technological advances have made producing several products using the hemp crop possible. People are becoming more knowledgeable about the various uses of hemp, and we can find hemp in a growing number of applications, from hemp oil to hemp seeds.
Hemp fabric is used within the textile industry to make clothes. It embraces hemp clothing for its durability and sustainability. As a naturally strong and lightweight fabric, it is perfect for many clothing applications like sustainable yoga clothes and
One of the reasons that make hemp a sustainable option for clothing is it is a carbon-negative raw material - the crop absorbs more carbon from the atmosphere than it releases.
Also, when compared with cotton, hemp requires less land to grow. Hemp is a high-yielding crop that can produce more on less land. It also requires less water. A study revealed that cotton requires 9,758 kg of water per kg. However, hemp requires 2,401 to 3,401 kg of water per kg1.
One of the biggest wins for hemp materials is that it doesn’t require pesticides, herbicides, or insecticides to grow. These chemicals are toxic to the environment, including the people and animals around the farmland. This distinguishes it from cotton, which requires a significant amount of these chemicals during farming.

Furthermore, hemp has a deep root system. This allows for constant soil improvement. Also, the entirety of the crop is useful. While the stalk is used for fiber, the hurds and leaves can be plowed into the soil to serve as fertilizer. This replenishes soil fertility and aids the growth of upcoming hemp fabric crops. As a result, it is a fact that industrial hemp enriches the soil it grows on.
During production, we can also see more of hemp’s eco-friendly nature. Since the whole plant is useful, it produces no industrial waste by-products. Manufacturers convert the stalks to textile fibers and woody parts into hemp products like eco-friendly dog beds and animal bedding.
However, because hemp can sometimes be rough in feel, manufacturers can blend it with synthetics. As a result, the biodegradability of hemp fabric blends can prove lesser than pure hemp material. Always check the label when looking for pure organic fabrics made from 100% natural fibers.
Clothes made from hemp fabric are often praised for their eco-friendly and beneficial qualities. These are some of the pros of one of the most eco-friendly fabrics in the world:
Highlighted below are the cons of hemp fabric:

This company uses natural and sustainable materials to make its clothes. These include hemp fabric, bamboo, and organic cotton.
Hemp fabric and linen fabric are both breathable and light when worn. However, hemp’s longer fibers make hemp fabric more durable than linen. This is because linen fabric has shorter flax fibers. When growing, farmers require less land to produce hemp. It also has a higher yield than linen.
The procedures of acquiring and manufacturing hemp fabric are more sustainable than bamboo fabric. Bamboo fabric is silkier and softer than hemp.
When comparing the sustainability of the fabrics, hemp is significantly more sustainable. The method of growing hemp requires less water and no synthetic fertilizers or pesticides.
Cotton, on the other hand, requires more of these ingredients for growth. However, cotton fabric is softer on the skin compared to hemp fabric. When it comes to durability, hemp is more durable than cotton.
