1. High precision detection function One of the characteristics of warp stop strips is the ability to accurately detect whether warp yarns are broken.

1. High precision detection function
     One of the characteristics of warp stop strips is the ability to accurately detect whether warp yarns are broken. It is usually installed on the warp stop frame of the loom, and when the warp yarn is broken, the warp stop strip can sensitively sense the change in warp tension. For example, in high-speed air-jet looms, the warp stop strip can accurately detect the breakage of even very fine warp yarns (such as 50D-100D synthetic filament). Its detection accuracy can reach the millimeter level, which is crucial for ensuring fabric quality. Because once the broken warp yarn is not detected in time, it can lead to defects in the fabric, such as missing warp.
2. Good conductivity (if it is a conductive type stop strip)
     Some stop strips are made of conductive materials. During the working process, when the warp yarn breaks, the circuit state of the stop warp strip will change. For example, in the warp stopping device of a rapier loom, the conductive warp stopping strip detects the state of the warp yarn by forming a conductive circuit with the warp yarn. Under normal circumstances, the warp yarn is connected to the electrode of the warp stop strip, making the circuit conductive; When the warp yarn is broken, the circuit is disconnected, and the warp stopping device can quickly send a signal to stop the loom. This conductivity enables fast and accurate transmission of end signals, ensuring that the loom stops running in a timely manner and reducing the production of defective products.
3. Stable mechanical performance
     The suspension strip needs to have good mechanical stability. It should be able to withstand certain external forces and long-term vibrations without deformation. During the high-speed operation of the loom, the warp stop frame will vibrate, and the warp stop strip must be able to be stably installed on the warp stop frame. For example, stop bars are generally made of high-strength metal or engineering plastics, with a reasonable structural design and sufficient rigidity. Even when the loom speed reaches over 1000 revolutions per minute, it can maintain shape stability and ensure that its detection function is not affected.
4. Wear resistance
     Due to the friction between the warp yarn and the warp stop strip during the weaving process, the warp stop strip needs to have good wear resistance. Especially when using yarns with coarse counts (such as cotton yarn with 40 or more counts) or yarns with relatively rough fiber surfaces, friction is more pronounced. In order to ensure the service life of the warp stop strip, its surface is usually treated with special methods, such as using wear-resistant coatings or selecting wear-resistant materials. For example, some warp stopping strips use ceramic coatings, which have high hardness and good wear resistance, and can effectively reduce the damage of warp friction to the warp stopping strips, making their service life several months or even years, depending on the strength of weaving and the type of yarn.
5. Good compatibility with the amenorrhea device
     The amenorrhea strip should be able to work well with different types of amenorrhea devices. Whether it is a mechanical or electronic stop device, the stop bar can serve as a key detection component. For example, in an electronic warp stop device, the signal output interface of the warp stop strip should be able to match the input interface of the electronic control system, correctly transmit the end signal to the control system, and enable the loom to stop in a timely manner according to the preset program. At the same time, in the mechanical stop device, the size and installation method of the stop bar should be adapted to the mechanical structure for easy installation and maintenance.
6. Strong adaptability (to different warp types and weaving environments)
     It can adapt to different types of warp yarns, including natural fibers (such as cotton, linen, wool) and chemical fibers (such as polyester, nylon, acrylic). Different warp yarns have differences in thickness, elasticity, strength, and other aspects, and stop warp strips can be effectively detected based on these differences. Moreover, the warp stopping strip can also adapt to different weaving environments, such as changes in temperature and humidity. In high temperature and high humidity environments, the physical properties of warp yarn may change, but the warp stop strip can still work normally to ensure the smooth progress of the weaving process.
