Elastane vs Lycra vs Spandex: What Are the Real Differences?
In the global textile supply chain, the terms elastane, spandex, and Lycra are often used interchangeably—sometimes even within the same technical document. While this casual usage may seem harmless, terminology accuracy matters in sourcing, specification sheets, labeling compliance, and performance expectations. For textile professionals, the real question is not which fiber stretches more, but whether […]
Is Elastane Good or Bad? Advantages and Disadvantages Explained for Textile Professionals
The debate around elastane—also known as spandex or Lycra®—often falls into an oversimplified trap: labeling it as wholly “sustainable” or “harmful.” For professionals in textile sourcing, development, and production, the real question is more nuanced: Does the functional value of elastane outweigh its trade-offs for my specific application? This analysis moves beyond polarizing takes to […]
How Is Elastane Made? Manufacturing Process, Quality Standards, and Testing Methods

Understanding the “how” and the “why” is crucial for achieving […]
Bio-Based Elastane — What It Is and Why It Matters
As the textile industry works to reduce its dependence on fossil fuels, bio-based elastane has emerged as a promising next-generation material. Made partly from renewable feedstocks such as castor oil or corn-based raw materials, it aligns with the growing sustainability requirements imposed by global brands and regulators. But is it a true breakthrough—or a transitional […]
Elastane Allergy: Causes, Symptoms, Treatment & Prevention
Elastane (commonly known as spandex or Lycra®) is a cornerstone of modern apparel, prized for its exceptional stretch and recovery. Found in everything from high-performance sportswear and comfortable underwear to everyday denim and shapewear, it adds comfort and fit to our wardrobes. While elastane is generally considered safe for most people, a growing number of […]
What is Elastane Fabric? The Complete Guide to the Stretch Fiber Revolution
In the vast tapestry of modern textiles, few fibers have woven themselves into the fabric of daily life as completely as elastane. This synthetic marvel, often hiding behind labels for spandex or Lycra®, is the silent architect of the stretch, fit, and freedom we now expect from everything from yoga pants to denim jeans. Its […]
The Differences Between Elastane vs. Polyester vs. Nylon: A Technical Guide for Textile Professionals
In the vast landscape of synthetic fibers, three titans dominate modern textile manufacturing: Elastane, Nylon and Polyester. While often grouped together as “man-made” materials, their chemical structures, performance characteristics, and optimal applications diverge significantly. Understanding the differences between Elastane vs. Polyester vs. Nylon is not merely academic—it is a critical competency for designers, product developers, […]
Covering Yarn Materials and Characteristics: A Technical Guide
The selection of covering material is a critical determinant in the performance and application of elastic covered yarns.
