Needle breakage is the most frequent and costly problem for Bangladesh knitting mills. A single broken needle can stop an entire machine for 15-30 minutes, leading to production delays, fabric waste and order rejections. For factories running 24/7 during peak season, just 1 hour of downtime can cost over 50,000 Taka in lost revenue.
Most needle breakage is preventable with proper maintenance and high-quality spare parts. In this guide, we break down the 7 most common causes of needle breakage and provide actionable quick fixes to keep your machines running smoothly.
The single biggest cause of needle breakage is using low-quality, generic needles. These needles are made with inferior materials and poor heat treatment, wearing out 2-3 times faster than premium needles. They are also more likely to snap suddenly during high-speed operation, damaging adjacent needles and sinkers.
Replace all generic needles with high-quality knitting needles for circular knitting machines from reliable suppliers. Premium needles may cost slightly more upfront, but they last 2-3 times longer and reduce downtime by 40%, saving you money in the long run.
Excessive or uneven yarn tension places extreme stress on needles, causing them to bend and break. This is especially common when producing elastic fabrics with spandex yarn, which requires precise tension control.
Inspect and calibrate your yarn feeding system weekly. Upgrade to a high-quality ShengSong electronic yarn feeder motor to maintain consistent, automatic tension control across all production speeds. This will reduce tension-related needle breakage by up to 70%.
Worn sinkers and cams create improper needle movement and excessive friction inside the machine. A single worn cam can cause dozens of needles to break in a single production run, leading to costly repairs and extended downtime.
Inspect sinkers and cams monthly for signs of wear, scratches or deformation. Replace worn components immediately to avoid cascading needle damage. Qattex offers custom cam manufacturing services to match any machine specification.
Incorrect machine timing causes needles to collide with sinkers, cams or other machine parts. This usually happens after maintenance or component replacement when timing is not properly reset.
Always adjust machine timing according to the manufacturer's specifications. Perform a timing check after every major maintenance or component replacement. Keep a timing log for each machine to ensure consistency.
Cotton lint and dust accumulate inside the machine, increasing friction and heat. Without proper lubrication, this friction causes needles to wear out prematurely and break unexpectedly.
Clean your machines daily and install a ShengSong SS30 automatic lubrication system. This system delivers precise, uniform lubrication to all moving parts, reducing friction and extending needle lifespan by up to 50%.
Even high-quality needles will break if installed incorrectly. Common installation mistakes include misaligned needles, loose needles and mixing different needle types in the same machine.
Train your maintenance staff on proper needle installation procedures. Ensure all needles are fully seated and aligned correctly before starting production. Never mix different brands or types of needles in the same machine.
Running machines above their recommended speed limits increases needle stress exponentially. While higher speeds may seem more productive, they lead to more frequent breakages and higher overall downtime.
Operate all machines within the manufacturer's recommended speed range. Monitor machine temperature and vibration regularly, and reduce speed if you notice any signs of excessive stress.
