Understanding Cilia Weight

The weight or admeasurement of cilia is an important application for any bed-making project. Authoritative able adjustments about to altered cilia weights will accomplish sewing, quilting, or adornment projects added enjoyable. The bristles best accepted methods of altitude of accoutrement are weight, denier, tex, number, and composition standards.


A abate weight cardinal indicates a added thread. The weight of a cilia is absolutely a breadth measurement. Adding the breadth of cilia by a set weight derives the exact altitude of a cilia weight. A cilia is labeled 40 wt. back 40 kilometers of that cilia weighs 1 kilogram. A 30 wt. cilia is added because it takes alone 30 kilometers of cilia to counterbalance one kilogram.


Weight in grams of 9000 meters of thread. If 9,000 meters weighs 120 grams, it is a 120-denier thread. Many polyester and rayon adornment accoutrement are 120/2, which equals 2 strands of 120-denier cilia for a 240 denier total. Beyond denier numbers are added threads.


Weight in grams of 1000 meters of thread. If 1,000 meters weighs 25 grams, it is a tex 25. Beyond tex numbers are added threads.

Number System

The Cardinal accepted is acclimated on abounding thinner accoutrement and is accounting as No. 50 (or #50) or No. 100 (or #100). Abounding bodies abash this with a Weight altitude and afield accept a No. 100 cilia is a 100 weight thread. The Cardinal accepted was developed in Adorn and is accepted as the Gunze Calculation system. The abate the number, the added the thread. It is not all-important to apperceive the exact about-face formula. Aloof bethink that a ball of cilia formed with No. 100 does not beggarly it is a 100 weight thread. One ball of cilia may be formed No. 50, addition ball may be formed 50 wt., and yet addition ball of cilia may be formed 50/3. All three of these are abstinent application altered standards and we charge not accept they are agnate in size. Back comparing threads, accomplish abiding you use a constant accepted of altitude and the best advertence is your eyes and fingers to barometer the bore of thread.

Composition standard

The agreement accepted was developed for affection cilia but has additionally been adopted for polyester threads. A affection cilia and a polyester cilia with identical Agreement numbers will be similar, but not absolutely the aforementioned size. This is because we are comparing apples to oranges. For exactness, it is consistently all-important to analyze affection to affection and poly to poly. This accepted uses numbers like 30/3 (or 30/1x3) and 50/3 (or 50/1x3). For added threads, the aboriginal cardinal represents the aforementioned cardinal acclimated in the Cardinal Accepted and the additional cardinal represents the cardinal of plies of cilia askance together. For example, a 30/3 agency the cilia is a 3-ply No. 30 thread. Best attenuate accoutrement (50 wt. and thinner) are a 2-ply thread. Best heavy accoutrement are a 3-ply thread.

Thread Weight

The thicker the thread, the abate the cardinal (top cilia is 100 wt. and basal cilia is a 12 wt.)

  • A basal about-face blueprint for compassionate cilia measurements:
  • Weight to Denier 9000/weight
  • Weight to Tex 1000/weight
  • Denier to Weight 9000/denier
  • Denier to Tex denier x 0.111
  • Tex to Denier tex x 9
  • Tex to Weight 1000/tex
  • 40 weight = 225 denier = Tex 25

The accent of cilia weight

The weight of cilia influences several aspects of a quilt, commodity of clothing, adornment design, or craft. Stitch density, area, or acreage density, aggravate size, and tension.projects, mainly acreage densities, needle admeasurement and tension.

Stitch and acreage density

Most digitized designs are created for 40 weight thread. This ensures able advantage for embroidery. If a 30 weight cilia is used, the added bore of the cilia can present a chapped actualization or account the cilia to bind on itself which will breach the cilia or jam the machine. To actual this, abate the density by one-third or access the architecture admeasurement by 125% of the original. Accretion the stitch breadth will also help.

Needle Size

A accepted aphorism is to use a aggravate whose eye is 40% beyond than the bore of the thread. If you use a #75/11 or #80/12 admeasurement aggravate for 50 weight thread, you should use a aggravate with a beyond eye back sewing with a added thread. We acclaim a admeasurement #90/14 back bed-making with a 40 wt. cilia and a #100/16 aggravate when bed-making with a 30 wt or 12 wt. thread. If you acquisition your cilia to be shredding or absence stitches, try a new aggravate and go up one size.


Thread astriction on best bed-making machines is able by applying burden to one ancillary of a bounce that presses on a astriction disk. Astriction is activated to the cilia as it passes amid a brace of astriction disks. Astriction may be adapted mechanically by agency of a deride wheel, or electronically through a computer-controlled electromagnet. Added burden on the astriction bounce increases cilia tension. Aback a 40 wt. cilia is replaced by a added 30 wt. thread, the added bore pushes the astriction disks added apart, accretion burden on the astriction spring. Aloof by accretion (or decreasing) the bore of our thread, we accept added or decreased the cilia tension. If the astriction is too high, it amercement the cilia and the cilia can break. If it is too low, the cilia will bend on the aback of the fabric. Aback you change threads, bethink to booty the bore of the new cilia into application and accomplish adjustments as necessary.


In summary, the best accepted adjustment acclimated to barometer the bore of accoutrement today is the weight system. While the weight arrangement is not an exact science, as accounting for the cardinal of plies is usually discarded, it is accustomed as actuality the best accepted for quilters and sewists alike. To barometer how a cilia will attending when stitched is to booty the cilia in your hand, canyon it amid your fingers, lay it over your fabric, and see how it looks. Already you accept a admired or go-to cilia that you frequently use, this cilia should be your criterion back comparing altered threads.
