From stalk to textile
Textile hemp starts as bast fiber. Long-line fiber can be spun on linen-type systems. Shorter fiber is often degummed or “cottonized”—chemically or mechanically refined so it can run on cotton spinning equipment, usually blended with cotton or other fibers.
Each step—retting, decortication, refining, spinning, weaving or knitting and finishing—may happen at a different company and in a different country. Ask suppliers to describe the whole chain.
Nonwovens, composites and bioplastics
Many industrial uses don’t need spinning. Needle-punched or air-laid nonwoven mats serve insulation, erosion control and molded parts. Fiber-reinforced composites use hemp for interior panels and other molded components. Fiber and hurd are also used as fillers in biobased plastics. These uses depend on consistent fiber length, low dust and controlled moisture.
Labeling and claims
Textile products sold in the U.S. generally must be labeled with their fiber content under the Textile Fiber Products Identification Act, enforced by the Federal Trade Commission. Environmental claims such as “sustainable” or “biodegradable” should be backed by evidence. Ask suppliers for the documentation behind any claim you plan to repeat.
Specifications to request
- Fiber type (long-line, tow or cottonized), length and fineness.
- Yarn count, twist, blend percentages and fabric weight (GSM or oz/yd²).
- Finishing chemistry, dyeing and any certifications claimed.
- Country of origin for each stage, plus traceability documents.
- Capacity, minimum order quantities, sample yardage and lead times.
Quick checklist for suppliers
- Fiber or yarn specification, blend percentage, weight and finish
- Production capacity, sample availability, testing and minimum order quantities
Describe your intended manufacturing process and required quality standards.
Frequently asked questions
What is cottonized hemp?
Cottonized hemp is hemp fiber that has been refined—by degumming or mechanical processing—so it is short and soft enough to spin on cotton spinning equipment, usually in blends.
Can hemp be used in plastics and composites?
Yes. Hemp fiber is used to reinforce molded composite parts, and hemp fiber and hurd are used as fillers in biobased plastics. Consistent fiber length, low dust and controlled moisture are key specifications.
Do hemp textiles need special labeling?
Textile products sold in the U.S. generally must disclose fiber content under the Textile Fiber Products Identification Act, which the Federal Trade Commission enforces. Back any environmental claim with evidence.
