Yarn is the type of thread used for sewing. It can be made of many different materials including cotton, linen, nylon, and silk.

Ingredients
Yarns are made of various materials. If the thread is stronger than the material used to join, if the suture is placed under the pressure the material may tear before the thread breaks. Clothes are usually sewn with yarn with a lower strength than cloth so that if stressed the seams will break before the garment. Heavy items that must withstand great stresses such as coatings, car seats, tarpaulins, tents, and saddles require very strong threads. Improvement efforts with lightweight threads will usually result in a rapid failure, although again, using a stronger thread than a sewn material may eventually cause a tear in the material before the thread itself gives way.
The polyester/polyester spun yarn is made by wrapping the polyester stapler around the continuous polyester filaments during spinning and plying these threads into a sewing thread. Core Spun Thread

Different weights
Yarn gauge
The yarn is measured by yarn density, which is explained by various textile measurement units related to the standard length per weight. These units do not directly correspond to the thread diameter.
Wt and Gunze sum
The most common weight system determines the length of the yarn within a kilometer required to weigh 1 kilogram. Therefore, greater weight number (indicated in the American standard with abbreviation wt ) indicates thinner and finer threads. The standard American thread weight is adopted from the Japanese Gunze Count standard which uses two numbers separated by forward slashes. The first number corresponds to the wt number of the thread and the second indicates how many fiber strands are used to construct the finished thread. It is common to wrap three strands of the same weight to make one thread, although this is not a formal requirement in US standards (which is therefore less informative).
Denier
The denier specification states how many grams are 9,000 meters of yarn weight. Unlike the general yarn load system, the larger the denier number, the thicker the thread. Heavy denier systems, such as general heavy systems, also determine the number of strands of the specified weight that are wrapped together to make the finished yarn.
Tex
Tex is a mass in grams of 1,000 meters of yarn. If 1,000 meters weighs 25 grams, it is tex 25. The larger tex numbers are heavier threads. Tex is used more commonly in Europe and Canada.
Aughts
Some yarn manufacturers, especially those producing very fine silk threads, apply their own yarn measurement scales using "aughts" or zero (unlike zero used in measuring grain size). In the given producer spectrum, "higher count" shows finer threads: these are usually given as single digits followed by forward and zero slots - for example, 3/0 shows three threads or threads of "000" size, but this figure has only significance when compared to other yarns produced by the same manufacturer: a 4/0 manufacturer will always be better than the same manufacturer it is 2/0, but it will not mean anything when compared to 4/0 of the manufacturer other. Therefore the scale is not suitable for conversion or comparison with other more common weight scales, although this is commonly used.
Conversion information
Conversion weights table
For example: 40 weight = 225 denier = Tex 25. The common Tex number for common sewing thread is Tex 25 or Tex 30. The slightly heavier silk buttons suitable for bartacking, small leather goods, and decorative stitching may be Tex 40 A heavy yarn and durable yarn, Tex 75. Heavy duty yarn for coat, bag, and shoe, Tex 100. A very strong topstitching yarn is suitable for trunk and tarpaulin, Tex 265-Tex 290. But good serging yarn, only Tex 13. For blindstitching and logging machines, Tex 8 is more subtle.
High temperature sewing thread
High temperature sewing thread provides durability and resistance to extreme temperatures. Some threads can be used for applications up to 800 Â ° C (1472 Â ° F). There are a variety of available sewing threads that have different applications and benefits.
Kevlar-coated stainless steel sewing threads have a high-temperature, refractory steel core combined with a Kevlar coating designed to facilitate engine sewing. The stainless steel core has a temperature resistance of up to 800 ° C (1472 ° F) and a heat-resistant Kevlar coating of up to 220 ° C (428 ° F).
PTFE glass-covered sewing threads have excellent temperature resistance combined with the PTFE lining to provide an easier sewing machine. The glass core has a temperature resistance of up to 550 ° C (1022 ° F) and a heat-resistant PTFE coating of up to 230 ° C (446 ° F).
Nomex sewing threads are inherently fireproof and heat resistant with a hard protective coating that is abrasion resistant during sewing operations. Hold the temperature up to 370 ° C (698 ° F).
Strongly bonded nylon sewing threads, coated with abrasion resistance, rotting proof, and have good tensile strength for lower temperature applications. They hold temperatures up to 120 Â ° C (248 Â ° F)
Strong hard bonded polyester threads, coated with abrasion resistance, dental wetting, and have exceptional tensile strength for lower temperatures but heavier sewing operations. They hold temperatures up to 120 Â ° C (248 Â ° F)
