A synthetic fiber doubling and twisting machine is a common type of textile machinery.
The synthetic fiber double-twisting machine is a common textile machinery that achieves two twists per revolution during the twisting process, dramatically boosting efficiency. It enables large-capacity, seamless winding and produces high-quality yarns.
Coating wire machine replaces traditional painting processes
The coating wire machine has widely replaced traditional painting techniques in this field, but to achieve optimal results, proper installation is essential before use. So, let us now walk you through the correct installation steps for the coating wire machine:

What is the core function of a sheathing machine?
By precisely controlling the wrapping angle, tension, and thickness, functional materials—such as metal wires, elastic fibers, and conductive yarns—are integrated with base substrates to achieve enhanced strength (e.g., carbon fiber-coated reinforced plastics), tailored elasticity (e.g., spandex-coated yarns for textiles), or specialized functionalities (e.g., conductive-coated filaments for smart wearable devices).
What is the trend of future coating technologies replacing paint?
The trend of future coating technologies replacing paint is shifting—from being driven primarily by cost and environmental pressures toward a focus on technological innovation and collaboration across the entire industry chain. At its core, this shift revolves around three key areas: material upgrades, intelligent process optimization, and expanded application scenarios. The specific trends are as follows:

The spindle of the doubling machine is lacking oil—oil up immediately.
Maintenance of multi-strand double-twist machines: Machine maintenance is an essential part of daily production. The quality of machine upkeep directly affects product quality, making both the content and standards of maintenance critically important.
What are the key steps for starting up a coating machine?
Clear the waste fibers from the suction gun's waste fiber bag to ensure smooth fiber flow.
How can the uniformity of spandex double-covered yarn be controlled?
Core yarn tension: Utilizing a magnetic-damping tensioner (such as the German Karl Mayer system), the spandex core yarn tension is monitored in real time, and the damping force is dynamically adjusted via PLC.
What are the technical advantages of an spandex double-covered yarn machine compared to a single-covered yarn machine?
The residual torsion of double-covered yarns is reduced by 60% compared to single-covered yarns, while the fabric's post-wash shrinkage rate drops from 3%-5% to 1%-2% (tested according to GB/T 8628-2013 standards), effectively addressing the industry challenge of "post-wash deformation" commonly seen in single-covered products.
What are the advantages of edgeless rolls compared to traditional hard-edge rolls?
Smooth unwinding: The soft-edge roll design features a seamless, non-ridged edge, eliminating the sharp protrusions found in traditional hard-edged rolls. This results in unwinding tension fluctuations of ≤±5% even at high-speed weaving speeds—such as 1200 rpm on jet looms—leading to a more than 50% reduction in yarn breakage rates. While conventional hard-edged rolls typically experience 2–3 yarn breaks per 10,000 meters, the edgeless design can reduce this rate to just 0.5–1 break per 10,000 meters or even lower.
