Typically, the Metric count system is employed for describing synthetic, spun, and corespun threads, whereas the English count system is reserved for cotton threads. For filament threads, Decitex or Denier is commonly used as the unit of measurement.
Thicker fabrics like denim require thicker threads, while delicate fabrics like silk need finer threads. Matching the thread size to the fabric type ensures that your stitches are both strong and aesthetically pleasing. For instance, larger denier sizes correspond to heavier threads, which can affect the appearance of seams and are preferred in specific sewing applications to ensure durability and prominence in the final product.
The Decitex (dtex) system is another variation of the Tex system. It measures the weight of 10,000 meters of thread in grams, often used for materials like polyester thread. Higher dtex values indicate thicker threads. This system is commonly used for sewing threads that require precise measurements.

The weight of a thread is actually a length measurement. Dividing the length of the thread by a set weight derives the exact measurement of a thread weight. A thread is labeled 40 wt. when 40 kilometers of that thread weighs 1 kilogram.
Understanding sewing thread sizes is an essential skill for anyone involved in sewing, whether you’re a hobbyist, fashion designer, or professional tailor. By mastering the various yarn number systems and knowing how to convert between them, you can ensure that your projects turn out perfectly every time.
Molding involves placing the reinforcement within a mold and injecting or pouring the matrix material around it to create complex shapes and structures, such as fiberglass components.
The orientation of Kevlar fibers within the composite is crucial, and unidirectional, bidirectional, or woven patterns can be used to tailor the mechanical properties, such as strength and stiffness, to specific needs.9
Composite materials, particularly carbon fiber, are extensively used in aircraft structures, including wings, fuselages, and interior components. Similarly, fiberglass and carbon fiber composites are used in everything from body panels to interior components, enhancing vehicle performance and safety.13
Each process is chosen based on the specific application and desired properties of the composite material, such as strength, weight, and flexibility.1, 2
The Cotton Count (Ne) system is primarily used for cotton threads. It measures the number of 840-yard lengths of thread in one pound. Higher Ne numbers indicate thinner threads. This system is often used in the United States and some parts of Europe.
Ceramic matrix composites (CMCs) are advanced materials made by embedding fibers within a ceramic matrix. Traditional ceramics are brittle; CMCs are engineered to overcome this limitation by incorporating fibers that enhance their toughness, making them more resistant to cracking and damage under stress.

Always test your chosen thread on a scrap piece of the same fabric. This allows you to see how the thread behaves with the fabric and make any necessary adjustments before starting your project. For instance, some sewists prefer nylon thread to match cotton upholstery, as it can help avoid visibility issues that heavier threads might cause in stitching.
Metal matrix composites (MMCs) combine metal matrices, such as aluminum, with reinforcements like ceramic or carbon fibers. These composites provide enhanced stiffness and wear resistance while maintaining the inherent ductility and thermal conductivity of the metal matrix.
Extrusion, on the other hand, pushes a mixture of the matrix and reinforcement materials through a shaped die to produce long, continuous composite products like pipes and rods.

Concrete, one of the most common and oldest composite materials, is extensively used in construction for its durability and versatility.6 It is created by combining cement as the matrix with aggregates like sand and gravel as reinforcements, allowing it to be molded into various shapes. When mixed with water, the concrete hardens and gains strength over time.
Concrete has several valuable properties, including resistance to weathering, erosion, and chemicals. It also has high thermal mass, allowing it to absorb and slowly release heat, contributing to building energy efficiency. While concrete is strong in compression, it is weak in tension and is often reinforced with steel bars to enhance its tensile strength.7, 8
Carbon fiber composites are extensively used in high-performance applications due to their remarkable strength and lightness. These composites maintain their mechanical properties over time, even under cyclic loading, making them durable in demanding environments.

Consider a thread with a Tex number of 20. Using the table, we can see that this translates to a dtex value of 200, a Denier of 180, an Nm of 50, and an Ne of 29.53. Such conversions are essential for sourcing the correct thread in international markets where different systems are prevalent. Additionally, selecting the right thread size is crucial for ensuring optimal performance with your sewing machine, as mismatched thread can lead to issues like jams or thread breakage.
The Number Metric (Nm) system measures the length of thread in kilometers per kilogram. For instance, an Nm 50 thread, such as certain polyester threads, means that 50 kilometers of this thread would weigh 1 kilogram. Higher Nm numbers indicate thinner threads, making this system opposite to the Tex and Denier systems.
Different stitch types may require different thread sizes. For instance, decorative stitches often use thicker threads to make the design stand out, whereas seams and hems may use standard-sized threads for durability. Lightweight fabrics, on the other hand, require a thinner thread to avoid issues like seam puckering and to ensure proper thread tension adjustments.

Similar to the Tex system, the Denier system measures the weight of 9,000 meters of thread in grams. A higher Denier number indicates a thicker thread. This system is often used for synthetic fibers, such as nylon and polyester, with nylon thread being a common example.
To use the conversion table, locate the thread size in one system, then read across the row to find the equivalent size in another system. This table simplifies the process of selecting the right thread size for your project, ensuring consistency and accuracy. It is especially useful for choosing the appropriate thread for different types of sewing machines, whether for home sewing machines or industrial sewing machines.
