Thread (textiles)

language culture Maturity 11-13 Next article →

Thread is a long, continuous strand of material used for various textile purposes. It is primarily used to join, create, or decorate fabrics.

While terms like yarn, cord, twine, and string are similar, thread is distinct. It is usually fine and smooth enough for delicate tasks like sewing, embroidery, or weaving lace. Yarn is typically thicker and used for knitting or crochet. Cords and strings are generally stronger and used for tying or fastening objects.

Choosing the correct material and strength is a critical part of sewing. If a thread is much stronger than the fabric, the fabric may tear under strain. Because of this, garments are often sewn with threads that are less strong than the fabric itself. This ensures the seam breaks before the garment is ruined. However, heavy-duty items like car seating, tents, and upholstery require extremely strong threads. Using lightweight thread for these heavy goods would result in rapid failure.

Many different materials are used to produce thread.

Cotton is a traditional choice for general sewing. Polyester is a synthetic blend that is stronger and more stretchy than cotton. Nylon is often stronger than polyester and can be transparent. For decoration, people use metallic threads made of fine wire or rayon for high sheen.

Silk is very fine and strong, though it can degrade over time. Linen is a thicker spun thread that can be waxed to resist mildew. Even specialized threads exist, such as water-soluble thread that dissolves in water for temporary basting.

Measuring thread requires understanding several different technical systems. One common method is the weight system, often abbreviated as "wt." In the American standard, a higher weight number indicates a thinner, finer thread. This system is related to the Gunze Count from Japan. The Gunze Count uses two numbers separated by a slash. The first number is the weight, and the second indicates how many strands of fiber make up the thread. For example, a "#60/3" thread has a weight of 60 and uses three strands.

Other systems provide different ways to define thickness and mass. Denier is a specification used for embroidery threads. It measures how many grams a 9,000-meter length of thread weighs. Unlike the weight system, a larger denier number means a thicker thread. In North America and Europe, many use the "tex" system. Tex measures the mass in grams of 1,000 meters of thread. A larger tex number indicates a heavier thread. For instance, a common sewing thread might be tex 25, while heavy-duty topstitching thread might be tex 100.

Specialized industries use even more specific scales and labels. Silk manufacturers often use a scale of "aughts" or zeroes to measure the finest threads. In this system, a higher aught count means a finer thread.

Commercial threads use specific denier-based sizes, such as 138 or 277. For extreme environments, high-temperature threads are necessary. Some threads use a stainless steel core and Kevlar coating to resist temperatures up to 800 °C. Other threads use glass cores with PTFE coatings to handle heat up to 550 °C.

Thread production has a very long history involving many different cultures. Ancient Egyptians were known to create thread using wool, hair, and plant fibers. Over time, the variety of materials has expanded to include highly processed cellulose like rayon and synthetic polymers like polyester. Today, the way thread is labeled provides deep information about its construction. Labels often show the fiber content and the number of "plies," or individual strands, wrapped together. This complex system of materials and measurements allows people to choose the perfect tool for any textile task.
