At Sky Swallow, we are committed to pushing the boundaries of textile technology to deliver premium-quality tactical and outdoor clothing. One such innovation that helps us stay at the forefront of fabric manufacturing is Sirospun yarn. Known for its superior strength, reduced hairiness, and enhanced durability, Sirospun yarn is a game changer for high-performance garments, especially those used in rugged environments. In this blog, we explore the benefits and applications of Sirospun technology, and why procurement managers seeking cutting-edge textile solutions should consider this yarn for their next clothing line.
What is Sirospun Yarn?
Sirospun, also called parallel-twist spinning, involves feeding two rovings (fiber strands) into the spinning process instead of just one. These rovings remain separate through the drafting zone, forming two small triangular areas before being twisted together into a single yarn. This technique gives the resulting yarn a unique structure with a look and feel similar to plied yarn—but with the efficiency and economy of single-ply spinning.
By using this technique, Sirospun yarn has qualities that set it apart from conventional yarns, especially when it comes to minimizing fiber hairiness, increasing strength, and improving wear resistance.
The Sirospun Process
Dual Fiber Feeding
Two rovings are fed in parallel into the spinning machine, maintaining a slight separation.
Pre-twist Formation
As the fibers move through the drafting zone, the twist begins forming before the two strands come together, resulting in a preliminary twist that reduces hairiness.
Unified Twist
Once the two fiber strands converge, they are fully twisted together, creating a yarn that combines the benefits of single-ply yarn with the strength of a plied yarn.
Benefits of Sirospun Yarn for High-Performance Clothing
For purchasing managers seeking top-tier fabrics for tactical and outdoor apparel, Sirospun yarn offers several advantages that make it an ideal choice for high-quality garments:
Reduced Hairiness
The Sirospun process dramatically reduces fiber hairiness compared to conventional spinning methods, which improves the appearance of the yarn and reduces pilling over time. This is especially important for high-end fabrics where a clean, smooth surface is essential.
Enhanced Durability
Sirospun yarn exhibits greater strength due to its twisted structure, making it more resistant to wear and tear. This quality is critical for tactical gear and outdoor apparel that are subjected to rough use.
Soft Hand Feel
Despite its strength, Sirospun yarn maintains a soft and smooth texture, making it comfortable for extended wear. Whether it’s a tactical uniform or outdoor activewear, garments made from Sirospun yarn strike the perfect balance between strength and comfort.
Breathability and Comfort
The compact structure of Sirospun yarn does not compromise on breathability. It is ideal for activewear and outdoor gear, where moisture-wicking and air circulation are important for wearer comfort.
Applications of Sirospun Yarn
Originally developed for wool spinning, Sirospun technology has evolved to become a favorite for producing high-quality blended yarns such as T/C (polyester-cotton) and CVC (chief value cotton). The yarn’s unique twisting technique also allows for innovative patterns and effects when different colored rovings are fed into the spinning machine, resulting in visually appealing fabrics.
Tactical Clothing
Sky Swallow’s tactical gear benefits greatly from Sirospun yarn’s strength and durability. The reduced hairiness and enhanced wear resistance ensure that the clothing holds up in harsh environments, offering long-lasting performance.
Outdoor Apparel
Sirospun yarn’s softness and breathability make it an excellent choice for outdoor wear like jackets, hiking gear, and activewear. The yarn provides a smooth finish with minimal pilling, ensuring garments look newer for longer, even after repeated use.
Eco-friendly Fibers
Sirospun is also being used to spin natural fibers like modal, Tencel®, and viscose, as well as 100% cotton. These fibers often have a tendency to develop hairiness during spinning, but with Sirospun technology, that issue is mitigated, producing fabrics that are soft to the touch, breathable, and resistant to fraying.
Sirospun vs. Conventional Ring Spun Yarn
While both Sirospun and ring spun yarns are used in high-quality fabric production, there are distinct advantages to choosing Sirospun for specific applications:
Less Hairiness
Sirospun yarn dramatically reduces long fiber hairiness, making it less likely to pill or fuzz, resulting in a cleaner, more polished fabric surface.
Increased Strength
The pre-twist feature of Sirospun yarn increases fiber cohesion, leading to stronger yarn and more durable fabrics, especially important for high-performance textiles.
Enhanced Design Flexibility
The ability to feed different colored rovings into the Sirospun process allows for unique yarn designs, such as AB yarns, which have a twisted, marled effect—ideal for creating visually interesting blended fabrics.
