What Is Rayon Fabric Made Of? A Guide for Textile Manufacturers

Rayon has long been celebrated for its silk-like softness, drapability, and breathability, but few stop to ask—what exactly is rayon fabric made of? Behind its luxurious texture lies a fascinating blend of nature and science. While rayon may resemble a natural fiber, its composition reveals a semi-synthetic identity that bridges the gap between organic cellulose and modern innovation.

Rayon fabric is made from purified cellulose, typically derived from wood pulp such as beech, pine, or bamboo. Through a complex chemical process, this natural raw material is transformed into a versatile textile fiber used in fashion, home textiles, and industrial applications.

This unique balance of natural origin and engineered performance makes rayon a compelling option for modern manufacturers who prioritize softness, sustainability, and flexibility in their product lines. But understanding rayon isn’t just about identifying its raw material. It requires a deep dive into fiber chemistry, production technologies, market applications, and environmental considerations.

To illustrate this complexity, consider this: one of SzoneierFabrics’ clients in Italy needed a lightweight, breathable, and biodegradable lining fabric for their luxury jackets. We developed a custom-dyed viscose rayon solution that exceeded both sustainability and performance benchmarks—something no synthetic alternative could offer. Curious how rayon can be adapted to different markets and products? Let’s start by examining the roots—literally—of what this fiber is made from.

1. What Raw Materials Are Used to Make Rayon Fabric?

Rayon originates from cellulose, a natural polymer found in plant cell walls. Most rayon is produced from wood pulp, primarily from fast-growing and renewable tree sources like eucalyptus, pine, beech, or bamboo. The selection of wood source directly impacts the fiber’s sustainability and cost-efficiency. Rayon fabric is made from regenerated cellulose derived from wood pulp—commonly sourced from eucalyptus, pine, beech, or bamboo—processed into fibers through chemical treatment.

Understanding the Origins of Rayon

Sources of Cellulose for Rayon Production

Chemical Ingredients Involved

• Sodium Hydroxide (NaOH) – Used to break down cellulose.
• Carbon Disulfide (CS₂) – Key in forming viscose rayon, but controversial due to toxicity.
• Sulfuric Acid (H₂SO₄) – Reconstitutes fibers during spinning.

Critical Considerations for Sourcing Cellulose

• Forest Certification (FSC): Ensures sustainable harvesting practices.
• Deforestation Risks: Unsustainable sourcing can harm ecosystems.
• Chemical Efficiency: Some processes recover and reuse solvents better than others.

Industry Insight

A 2024 report by Textile Exchange revealed that over 62% of the global rayon supply chain still relies on uncertified wood pulp, creating environmental and brand reputation risks. As demand for eco-textiles grows, manufacturers who source from FSC-certified suppliers can gain a competitive edge.

2. How Is Rayon Fabric Manufactured from Cellulose?

Rayon manufacturing involves chemically converting natural cellulose into a fiber that can be spun into yarn and woven into fabric. There are three major methods: viscose, modal, and lyocell. Each method has unique environmental and performance characteristics.

Rayon is produced by dissolving cellulose from wood pulp and regenerating it into fiber through one of three main methods: viscose, modal, or lyocell.
