Elastic Machine Ki Sui – Multi-Needle Chainstitch Needle for Kansai Special & Union Special Machines

Best for garment units and tailoring workshops running Kansai Special or Union Special multi-needle machines for elastic attaching, belt-looping, and chainstitch work on stretch fabric, fine knitwear, and light wovens.

Why This Needle

Elastic and stretch fabric punishes a needle that isn’t matched to it — skipped stitches, thread fusing, and bent points are the usual complaints on multi-needle machines run at factory speed. This needle is stocked genuine across three trusted brands and the full size range factories actually ask for, so one listing covers light innerwear knits through heavier elastic waistband trims without hunting across multiple product pages.

Features

• Genuine stock in three trusted brands: Groz-Beckert, Flying Tiger, Organ
• Straight needle with double long groove for smoother thread feed at high machine speed
• Full size range from 09/65 to 21/130 — one listing, not six separate ones
• Regular round point and Gebedur (gold-titanium coated) options
• Fits both Kansai Special and Union Special brand multi-needle machines

Use Cases

• Elastic attaching on innerwear, sportswear, and lingerie
• Belt-loop and waistband stitching on stretch trims
• Multi-needle chainstitch and decorative stitching on knitwear
• General multi-needle work on fine wovens and thin leather

Benefits

• Matching needle size to fabric weight cuts skipped stitches and thread breaks on elastic material
• The Gebedur-coated option resists heat buildup on synthetic elastics, which is what usually causes thread fusing and burn marks at high speed — useful for multi-shift factory runs
• One needle covers several machine-manual naming conventions, so you’re not guessing whether a different code is a different part (see specs table)

How to Fit This Needle

First, match the needle size to your fabric weight — finer 09/65–11/75 for light knits and elastic, heavier 16/100–21/130 for structured trims and thicker webbing. Next, loosen the needle clamp screw on your Kansai Special or Union Special machine and remove the old needle, noting how the scarf faces. Then, insert the new needle with the scarf oriented per your machine’s manual and push the shank fully into the clamp. Finally, tighten the clamp screw, hand-turn the machine to check clearance, and run a test seam on scrap fabric before starting production.

FAQs

Which machines use this needle system?

This needle is sold under several different reference codes depending on the manufacturer or manual — check the specs table above for the full cross-reference list. It’s the standard needle for Kansai Special and Union Special brand multi-needle machines used for elastic attaching, belt-looping, and multi-needle chainstitch work.

Which size should I use for elastic and stretch fabric?

For light elastic, jersey knits, and fine lingerie fabric, start with 09/65 or 11/75. Mid-weight stretch fabrics and sportswear typically need 14/90, while structured elastic trims and thicker webbing call for 16/100 to 21/130. Too fine a needle on heavy elastic bends or breaks; too heavy a needle on light knits leaves visible holes.

What’s the difference between the regular point and the Gebedur-coated version?

The regular round-point needle handles everyday elastic and knit work fine. The Gebedur (gold-titanium coated) version resists heat buildup and friction better, which matters on synthetic elastics and coated fabrics that tend to fuse or scorch around the stitch at high machine speed — factories running multi-shift production usually get longer needle life from it.

Does this needle work on plain knitwear and light wovens too, not just elastic?

Yes — beyond elastic attaching, this needle system is also rated for fine knitwear, woven fabrics, and thin leather work such as shirts, blouses, and trousers, so the same needle covers both stretch and non-stretch jobs on a compatible multi-needle machine.

Will this needle fit my Kansai Special multi-needle machine?

Yes — this is the standard needle system for Kansai Special multi-needle machines used in elastic attaching and belt-looping. If your machine’s needle chart lists a different reference code, check the specs table above — it’s very likely the same needle, not a different part.

Can I use this on a Union Special machine too?

Yes. This needle system is also the standard fit for Union Special brand multi-needle machines running the same chain-stitch class-400 system — you don’t need a separate needle for each machine brand as long as the system matches.
