Simple understanding of the rules of clothing production

202 is a 2-strand thread made by twisting 20 strands of raw yarn into 2 strands. 203 and 402 are written in the same way. The accurate way to write 202 is 20S/2, where S is an imperial unit. Secondly, 202203402 are both short fiber lines, and the unit S is commonly used in short fibers. The larger the value in front of S, the thinner the line. The most famous short fiber thread made is the British coats. Let's talk about long silk threads again. Generally, the unit for long silk threads is D, which is Daniel. The larger the value before D, the thicker the thread (opposite to the unit S). For example, the Japanese made 100 # long thread has a weight of 50D/2, where D represents the weight per 9000 meters of yarn. A roll of 5000 meters of 100 # long thread sewing thread has a weight of (50/9) * 2 * 5=56 grams. The best ones for making long silk threads are GUTERMANN from Germany, AMANN from Germany, and KING from Japan. 

60S/3 is a line consisting of 60 legs and 3 shares And 60S/4 refers to 60 pieces with 4 strands. Generally, 60S/3 is more commonly used on clothes, while 4 strands are rarely used The English for polyester core thread is: POLY/POLY CORE SPUN SEWING THREE. Generally, core thread is a high-end thread that is relatively expensive in price. Japanese customers prefer to use long thread, while European customers prefer to use core thread. Both long thread and core thread are top-quality sewing threads. Strictly speaking, the thickness of the fabric varies depending on the specifications of the thread, and different parts of the clothing also require different specifications of thread But generally, those who don't have strict requirements don't pay much attention to this aspect, the key is to look at the value of the clothing
