A "rubber cord" refers to a type of elastic tape or cord made primarily by inserting natural rubber or polyurethane elastic threads as the core, and then weaving, knitting, or braiding around it with threads made of polyester, nylon, rayon, PP, and other materials. In the industry, it is classified in a bit more detail, and "rubber cord" often specifically refers to flat rubber or round rubber made using a cord-making machine, where several natural rubber or polyurethane elastic threads are intertwined with side threads (such as polyester, nylon, rayon, etc.) in a crossing manner. *For more detailed information, please refer to the related links. Feel free to contact us for further inquiries.*

Call rubber is a product commonly referred to as "rubber cord." It is manufactured using a braiding machine, where several strands of natural rubber or polyurethane elastic thread are intertwined with side threads (such as polyester, nylon, or rayon). In terms of product structure, call rubber corresponds to a braided structure, woven rubber corresponds to a woven structure, and knitted rubber corresponds to a warp-knitted structure. Additionally, call rubber is classified as "flat rubber," but it is also possible to produce "round rubber" using the same type of braiding machine. In the case of round rubber, one or more core rubber strands are bundled together. *For more detailed information, please refer to the related links. Feel free to contact us for further inquiries.

Call rubber is generally referred to as 4-call, 6-call, 8-call, 10-call, and 12-call, but what does "call" mean? (In English, it translates to "code.") "Call" refers to the number of core rubber threads (natural rubber or polyurethane elastic threads) inside. Since rubber threads come in various thicknesses, using thicker threads or rubber threads to make products results in a wider width and greater thickness. It is not measured in millimeters of width, so please do not confuse it. *You can view the detailed content of the article through the related link.

This is one of the finishing methods for call rubber. The call rubber is wound around a core rod and a brim bobbin made of thick paper. There are several sizes of brims available, and the choice depends on the thickness of the product and the number of meters to be wound. Typically, the winding comes in 150m and 300m lengths. We have posted images of the winding process for Lycra call rubber in the related links, so please take a look. *You can view the detailed content of the article through the related links.

A common complaint regarding the sewing of call rubber is the phenomenon known as "slip-in." This phenomenon occurs when the cut edge of the call rubber is stretched several times with strong force, causing the "core rubber" inside to float and lose its ability to return as a rubber cord. Visually, the end of the rubber thread floats and has nowhere to go, resulting in a wavy appearance. This phenomenon is an unavoidable issue due to the characteristics of the structure of call rubber. As a solution, when sewing the cut edge of call rubber, it is important to take as much seam allowance as possible and sew firmly to prevent the rubber thread from coming out. Therefore, during ring processing, we recommend using a longer seam allowance with "ears." *For more detailed information, you can view the related links.

In the textile industry, commonly used units include "denier" and "decitex." These units are often referred to as constant-length counts and are frequently used for long fibers such as synthetic fibers. (However, among natural fibers, silk is considered a long fiber.) Denier is often written as "d," while decitex is written as "T" or "dtex." Denier refers to the weight of the yarn at 9,000 meters; for example, if a polyester yarn weighs 150 grams at 9,000 meters, it is 150d (denier). (If it weighs 1 gram at 9,000 meters, it is 1 denier.) *You can view the detailed content of the article through the related links. For more information, please feel free to contact us.*

This article introduces a simple method for measuring thread thickness. As an example, we will explain how to investigate the thickness of polyester thread, assuming there are two types of thread as shown in the "image," with the thickness of the pink thread being unknown.

The main causes of significant complaints and issues with rubber in apparel products are largely due to the fact that most rubber usage does not undergo testing, particularly as a result of a "cost-focused" approach. If one aims to pursue perfect rubber, it is necessary to conduct all of the aforementioned tests. However, recently, when issues with these tests have arisen, the situation has become increasingly prevalent where consumers do not repurchase those products, indicating that at least minimal testing is now required. *For more detailed information, please refer to the related links.

One of the finishing methods for braided cords and round rubber is called "kase-maki." It is a method of winding using a "waku" that allows for length adjustment. Depending on the thickness of the product, there are 50m rolls and 150m rolls available. We have posted images of the acrylic color code being wound in the related links, so please take a look. *You can view the detailed content of the article from the related links.

One more important aspect of the quality of elastic bands is what I consider to be "wearing comfort." For example, have you ever experienced the following situations? "The waistband of my underwear is too tight and digs into my waist, causing pain." "Even though my underwear is still new, the waistband is loose and keeps slipping down." "I find it comfortable for some reason, so I end up wearing the same underwear all the time." "Even though it's new, there are some underwear I tend to avoid wearing." "I unconsciously end up buying underwear from the same brand." I believe these situations arise because we are subconsciously aware of wearing comfort. Of course, it's not just an issue with the elastic; there are various factors such as design, material, and sewing methods that play a role, but the elastic component is also very important. *You can view more detailed content of the article through the related links.

The machine that makes rubber cords is called a "cord manufacturing machine." When a bobbin with thread is set on the cord manufacturing machine and rubber thread is set and activated, the bobbin spins around the rubber thread at high speed, creating the rubber cord. Rubber cords can be broadly divided into flat rubber and round rubber. Although the appearance of the cord manufacturing machines for flat rubber and round rubber is almost the same, what exactly is the difference? *For more detailed information, you can view it through the related links.

In our industry, the rubber threads (elastic threads) we use can be broadly categorized into "natural rubber," "polyurethane," and "synthetic rubber." Natural rubber, as the name suggests, is made from the latex extracted from rubber trees. Commonly known items like "rubber bands" are made from natural rubber, but since they are made with the raw components, their durability is poor, and they tend to break over time. The rubber threads used by Nisso are manufactured by "Rondex" in Thailand and are known as "SSDX" and "LKX," which incorporate special chemicals along with the rubber latex, providing durability and longevity. Additionally, there is a high-quality rubber thread called "NDX," which is made by mixing synthetic rubber with natural rubber. All of these Rondex rubber threads have a round cross-section. Square rubber is manufactured through a completely different process than round rubber. *For detailed information, please refer to the related links. Feel free to contact us for more details.*

It seems that some customers occasionally use woven rubber by making holes in it. This is a very dangerous usage method that can lead to complaints due to the structure of the woven rubber. The structure of woven rubber consists of threads and rubber threads running vertically, with horizontal threads woven in by crossing them up and down. Therefore, woven rubber stretches in the vertical direction but does not stretch in the horizontal direction. Making a hole in the woven rubber means cutting the rubber threads that run vertically, so when you pull the rubber after making a hole, the rubber threads can slip out, causing it to ripple or stop stretching. Please be careful with any processing methods that cut the rubber threads. *For more detailed information, you can view it through the related links.
