In the garment manufacturing industry<\/strong>, understanding the specifications for sewing threads is extremely important. These specifications help you choose the right type of thread for each product. In this guide, you will learn how to read and analyze values like \u201c60\/3\u201d, \u201c40\/2\u201d, \u201c20\/6\u201d, \u201c40\/3\u201d, etc…, <\/strong><\/em>and understand the fineness, strength and performance characteristics of each type of thread. This knowledge will improve your product quality and optimise your production process<\/a>. Let\u2019s explore the details.<\/p>\n

Construction of Sewing Thread in the Garment Industry<\/h2>\n

Sewing thread<\/a> is made up of multiple single filaments twisted together. The number of filaments involved directly determines the strength and robustness of the thread. The thread\u2019s construction doesn\u2019t only affect strength\u2014it also influences how well the thread works with different types of fabric<\/a>. For example, a \u201c40\/2\u201d thread means<\/strong> that two filaments (of a fineness rating of 40) are twisted together; this is a common type of thread in standard garment manufacturing<\/a>. When choosing sewing thread<\/a>, understanding its construction helps you make more precise decisions.<\/p>\n

\"\"<\/p>\n

Threads that use a larger number of twisted filaments<\/a> (i.e., a higher second number \/ \u201cY\u201d in X\/Y) tend to have better tensile strength and are suitable for products that require high durability. This is an important factor because it influences the final product quality\u2014strong, well-made seams contribute significantly to both durability and appearance.<\/p>\n

Tex \u2013 Thread Thickness<\/h3>\n

\u201cTex\u201d<\/strong> is a unit used to measure the weight of a thread, indicating how many grams 1,000 metres of the thread weigh. When you see values like \u201c18\u201d, \u201c21\u201d, \u201c30\u201d, \u201c40\u201d, etc…,<\/strong> they represent the Tex value and hence the thickness of the thread<\/a>.<\/p>\n
