Global Raw Material Comparison: PP, PET, Viscose

Introduction: Why raw material selection defines the entire nonwoven industry

In the global nonwoven fabric industry, most buyers focus on:

• GSM

• Fabric type (spunbond, spunlace, SMS)

• Price per kilogram

However, experienced procurement teams know a deeper truth:

More than 70% of nonwoven performance is determined at raw material level.

This is why Global raw material comparison: PP, PET, viscose is not a theoretical material science topic—it is a direct procurement profitability model.

Every decision in hygiene, medical, industrial wipes, agriculture, and filtration products starts from this comparison.

The purpose of this article is to provide a full engineering and procurement breakdown of Global raw material comparison: PP, PET, viscose, based on:

• Fiber physics

• Cost structure

• Processing compatibility

• Application performance

• Lifecycle economics

• Global supply chain behavior

By the end, you will not only understand Global raw material comparison: PP, PET, viscose, but also how to use it for real sourcing decisions.

1. Fundamental material architecture

1.1 PP (Polypropylene) structure behavior

PP is a thermoplastic polyolefin with:

• Hydrophobic surface

• Low density (0.91 g/cm³)

• High processability

• Excellent melt spinning capability

In Global raw material comparison: PP, PET, viscose, PP is the dominant material for spunbond and meltblown nonwovens.

1.2 PET (Polyethylene Terephthalate) structure behavior

PET is a polyester polymer with:

• High tensile strength

• Thermal stability up to ~250°C

• Excellent dimensional stability

• Strong recycling ecosystem

PET is widely used in industrial spunbond and reinforcement layers.

In Global raw material comparison: PP, PET, viscose, PET represents the engineering-grade durability material.

1.3 Viscose structure behavior

Viscose is regenerated cellulose:

• Hydrophilic

• High liquid absorption

• Soft tactile feel

• Biodegradable under certain conditions

In Global raw material comparison: PP, PET, viscose, viscose represents the functional performance fiber for hygiene and wipes.

2. Mechanical performance engineering comparison

Mechanical performance is critical in nonwoven applications such as:

• medical gowns

• wipes

• packaging

• filtration media

7. Supply chain risk analysis

Each material carries different global risk factors:

PP risks

• crude oil dependency

• geopolitical energy fluctuations

PET risks

• recycling cycle dependence

• industrial capacity concentration

Viscose risks

• pulp supply fluctuation

• environmental regulation pressure

This risk layer is critical in Global raw material comparison: PP, PET, viscose.

Procurement teams should not evaluate materials in isolation.

Instead they use:

• cost per functional unit

• absorption per gram

• strength per GSM

• lifecycle durability index

This is the real framework behind Global raw material comparison: PP, PET, viscose.

9. Common procurement mistakes

Many buyers fail due to:

• choosing PP purely for low cost

• overusing viscose without durability consideration

• ignoring PET reinforcement applications

• misunderstanding GSM-material interaction

These mistakes distort Global raw material comparison: PP, PET, viscose decisions.

10. Hybrid material trend (industry evolution)

The market is shifting toward:

• PP + viscose composite spunlace

• PET reinforced spunbond layers

• biodegradable viscose blends

• multi-layer SMS systems

This evolution redefines Global raw material comparison: PP, PET, viscose.

11. Future outlook (2026+)

Expected trends:

• viscose supply tightening
