How to Select the Right Needle: For Commercial/Industrial Machine Needles
ROUND SHANK NEEDLES
16x257: (Groz-Beckert - Organ) This is the standard sewing machine needle that other needle makers offer for Tajima and similar embroidery machines. It was originally designed for high speed sewing machines and does fine for that purpose.
DB-K5: (Groz-Beckert - Organ) DBxK5 This needle is virtually the same as 16x257 but has a significant feature designed especially for embroidery machines such as Tajima. The DB-K5 needle has a one size larger eye than that found in a 16x257 needle. For example, a DB-K5 size 10/70 needle has an eye which is at least as large as the eye in a 16x257 size 12/80. Unlike sewing thread used for general apparel sewing, embroidery threads are ”fluffier” and have less tensile strength. A larger needle eye, without increased blade diameter, allows the embroidery thread to pass easily through the needle’s eye without fraying or snapping.
DBxK5Z1: This is a modified version of the DB-K5 needle. It has a side scarf, long extended groove, longer deeper scarf and slim Xtra Light Ballpoint. The side scarf allows less interference between the needle and the rotary hook. The long extended groove provides more protection to the top thread. The longer deeper scarf allows the hook point to be adjusted closer to the center of the thread loop and allows for variations in registration from one needle position to the next. The slim point reduces penetration resistance for smoother piercing of the material. This all adds up to smoother, sharper embroidery.
BALL POINT: Ball Point needles are designed to alleviate making holes in knit or loosely woven materials. The cross fibers which constitute the knit or loosely woven materials are relatively far apart as compared to those in tightly woven materials. When a needle with a standard ”set” or "sharp” point encounters one of those fibers in penetrating the fabric, it cuts right through the fiber. This creates a hole in the fabric. The Ball Point needle pushes aside the fiber it encounters in penetration and thereby avoids making a damaging hole in the fabric. (It is also recommended to use the thinnest possible needle for a particular fabric).
DB-K5kk DBxK5KK (Short Shank): The short shank needles are intended for use in machines with raised needle hole throat plates like in ZSK and Singer KSM models. They are also used to allow more needle penetration in very thick materials thus avoiding “shanking.” CAUTION: With a shorter shank length the needle blade has less support and is prone to deflect more than regular needles. When using short shank needles, the use of a thicker size may be required to avoid excessive needle breakage.
DBx9ST: This needle is intended for some extreme situations which have thicker than usual embroidery threads and do not allow you to increase the needle thickness. The eye of a DBx9ST needle is at least two (2) sizes larger than ordinarily found in a given size needle. For instance, a DBx9ST size 9/65 has an eye of at least the size found in a 16x257 size 12/80.
DBx7ST: The eye of the DBx7ST is designed particularly for metallic type embroidery threads. The eye of this needle is shaped like a rectangle. The special eye design facilitates the passage of metallic threads through the needle’s eye.
DB-K5SS: The DB-K5SS needle has all the eye features of the DB-K5, but the point has a very narrow wedge to make penetration through leather, vinyl and similar materials easier and neater. A standard “set” or “sharp” point needle punches its way through leather like materials which may make irregularly or undesirably shaped needle holes. The very narrow wedge point “slices” through the leather like materials while making a cleanly cut needle hole. Other available wedge point needles typically have longer wedges than the DB-K5SS needles. That’s fine for most sewing operations, but in embroidering, the stitches are very close together. The longer wedge point needles will actually punch out the design created by the close pattern of embroidered stitches. The extra narrow wedge point of the DBK5SS leaves enough distance between stitches in embroidered patterns to maintain the strength of the leather like material and avoid punching out the embroidered design.
DB-K5SD1: This needle has all of the features of the DBK5 sharp point needle with the addition of a small triangular tip and a titanium (PD) finish. This very small triangular tip improves the penetration of hard materials like leather, for smoother stitching.
For: FINE KNITS
DBx1KN: This is a modified version of the 16x257 needle specifically for sewing thin knit fabrics. It has a slender, straight blade with a longer, tapered Thin Ball point and a revised profile around the eye. The slender, straight blade acts the same as using a one size thinner needle with a consistent slim shape. The longer taper of the needle point reduces the penetration resistance in fabrics to minimize needle holes. The profile around the eye is reduced, to avoid the extra penetration resistance the normal bulge causes.
DBxK23: This is the large eye version of the DBx1KN. The area of the eye is increased approximately 25% to accommodate heavier, thicker or “fluffier” threads with less stress in an embroidery application.
DF-M20: This needle has all of the features of the DBx1KN needle with the addition of a flat shank and a longer scarf. It is made specifically for the Tajima Hem-Stitching machine.
For: MEISTERGRAM XL & XLC
(Others use DB-K5)
1906: (Groz-Beckert - Organ) This is the heavier shank needle with a special scarf for the large bobbin Meistergram machines. It has a standard eye to blade relationship. It is available in regular and ball point, with chrome, Cool-Sew or PD/titanium finishes.
For: FINE KNITS
DPx5KN: This is the heavier shank needle with a slim blade, larger eye and the longer slimmer KN point. It is currently available in size #9/65, with a Ball Point and PD/titanium finish. It works well for sewing lettering or crisp designs on fine knits.
For: CHAIN STITCH & CHENILLE
PH-C70: CEx3; This is the hook needle for chain stitching with a flat spot on the shank, used in the Tajima.
PH-C70SB: CEx1; This is the hook needle with a short barb for chenille with a flat spot on the shank, used in the Tajima.
PH-C120: This is the hook needle for chenille, with a smaller hook opening to avoid snagging on delicate fabrics, with a flat spot on the shank, used in the Tajima.
253: 137x1; This is the screw shank, hook needle for chain stitching, used in Melco, Cornely, Singer 114, Consew 104 & 133, Treasure, etc.
253SB: This is the screw shank, hook needle with a short barb for chenille, used in Melco, Cornely, Singer 114, Consew 104 & 133, Treasure, etc.
