How do you calculate the fabric consumption for knit garments?

Answer:

Firstly, you've to know what you going to make or about the measurement? All measurement has it LENGTH & WIDTH. Equations as bellow-
# Body Length + Sleeve Length + 10 (for folding {sleeve & bottom}) * (Chest width + 4 C.M.) * 2 / 10,000 * G.S.M. (Gram per square meter) Range / 1000 * 12 * 10% (wastages)
= K.G. per Dozen

 How do you calculate woven shirts fabric consumption?
 Answer:

If we see in measurement chart, for size-"L"

1.     
Center back (CB) lenth is 74 cm

2.     
i.e, 74/2.54 inch = 29.13 inch

3.     
Sleeve length is 68 cm

4.     
i.e, 68/2.54 inch = 26.77 inch

5.     
Chest measurement is 58*2 cm = 116 cm

6.     
i.e, 1/2 chest is 116/2 = 58 cm. i.e, 58/2.54 inch = 22.84 inch



Per pc consumption formula is :
(Back length+Sleeve length + 6) * (1/2 chest + 4 ) * 2 / Fabric width * 36 ( in yards )
(Back length+Sleeve length + 6) * (1/2 chest + 4 ) * 2 / Fabric width * 39.37008 ( in meters )
= ( 29.13+26.77+6 ) x ( 22.84+4 ) x 2 / 60 /39.007 =


Weight or Measure
in the Freight Cost Calculation


The freight rate on export goods is often based on W/M (weight or measure), that is, based on the weight or the volume of cargo (the cube or measurement of cargo). The rate uses the comparative relation between weight and volume of cargo. A cargo that is large in relation to its weight is charged according to its total cube, while a cargo that is heavy in relation to its size is charged according to its gross weight.

In general, light cargo is charged based on measure, while heavy cargo based on weight. Most sea consignments are charged based on measure, while most air consignments are charged based on weight.

The freight cost by weight or measure that will give the carrier the higher revenue is the rate that applies.

The unit of ton being used in the freight cost calculation may differ among carriers. It can be a metric ton (2204.6 lbs. or 1000 kgs.), a short ton (2000 lbs. or 907 kgs.), or a long ton (2240 lbs. or 1016 kgs.). The exporter must verify with the carrier which unit is being used. In practice, the most frequently used is the metric ton.

About the CUBIC METER & W/M = Weight or Measurement in respect of shipping ocean freight from the USA

We found that people that shipping freight from or to the USA by sea, using an international ocean freight service, sometimes miss understand meaning of cubic meter. This page is created to help to understand the meaning of cubic meter in respect of international cargo transportation from the USA by sea.

  • One cubic meter is a considerably large volume for your ocean freight shipment
  • A cubic meter is a measurement of volume, that takes your ocean freight shipment, and is equal to space of one meter wide, one meter long, and one meter high.
  • One metric meter = aprx. 3.28 metric feet
  • ONE CUBIC METER = aprx. 35 CUBIC FEET

This image from www.wikipedia.org should help you get a picture of one cubic meter

                                         

A cubic meter is something 1 meter long by 1 meter wide by 1 meter high
(or 3.28 feet long by 3.28 feet wide by 3.28 feet high)

  • 1m * 1m * 1m = 1 CUBIC METER
  • 3.28ft * 3.28ft * 3.28ft = 35 CUBIC FEET = 1 CUBIC METER

Technically cubic meter could be any combination of lengths as long as all three dimensions multiplied together equals 1.

  • 0.5m * 0.5m * 4m = 1 CUBIC METER
  • 5ft * 7ft * 1ft = 35 CUBIC FEET = 1 CUBIC METER

Garment Barcode

 

 

Every garment can be uniquely identified when displayed as Style / Colour / Size. A barcode (Sku, Plu, UPC other terms) can be manually assigned or automatically generated in the Niche Garments application.

 

Niche Garments allows for 2 methods of barcodes. A company should only use one method, either EAN (Australian Standard) or Niche Garments own method (Style / Colour / Size).

 

Which Method

Choosing a format will often be dictated to whom you supply too. Major retail chains may require you to use the EAN standard. Otherwise if you are supplying your style file to others that do not need an EAN you can use Niche Garments own internal method to generate barcodes.

 

Bar-coding is Seasonal

When you generate barcodes only one season at a time can be done.

 

Barcodes can have a maximum length of 15 characters

Niche Garment only supports barcodes up to a maximum length of 15 characters.

 

EAN Method

Generate EAN numbers for every Style / Colour and Size in the current season. See EAN Barcode

 

Style / Colour / Size Method

Use Niche Garments own method to generate barcodes. See Style / Colour / Size.

 

Printing Barcode

Niche Garments currently supports Code 39 for the printing of barcodes. If EAN barcodes are required to be printed then an external report program is used to print these barcodes contact Niche Support for further assistance.

 

Manually Entering Barcodes

Sometimes you need to manually need to type in barcodes. This can be done directly from the Garment Stockview or Style Maintenance screens.

 

Caution

Never delete or change barcode numbers if you have provided an external company with a current barcode list.

 

Duplication of Barcodes

Technically Garments are treated separately between seasons, however a barcode for a garment can be the same between season. However never use an old barcode for a new style.

 

 

 

 Introduction

It is important to know the amount of thread consumed in a sewn product so you can: 1) Estimate the number of cones needed; and 2) Calculate the cost of the thread needed to manufacture the finished product. Thread consumption can be determined in several ways.

To calculate the amount of thread in a seam, you can:

  • Measure the actual amount of thread consumed in a specific length of seam.
  • Calculate the thread consumption by using mathematical stitch formulas based on the thickness of the seam and the number of stitches per inch.
  • Calculate the thread consumption using thread consumption estimates.

Measuring Actual Thread Consumed

 

A specified length of the seam, for example 3 inches, is measured on the seam and then the thread is removed by carefully unraveling the stitch. You can then calculate the amount of thread consumed in one inch and multiply this factor times the total length of the seam measured in inches. (Obviously, you must do this for each seam to determine the total amount of thread consumed in the finished product.)

Example:
  • Length of seam is 42 inches or 1.17 yards.
  • Stitch and seam construction: 401 SSa-1.
  • Specified length of thread removed from a seam equals 3 inches.
  • Needle thread removed = 9 inches
  • Looper thread removed = 8 inches
Calculation:
  • Needle thread factor = 9 ¸ 3 = 3 inches of needle thread per inch of seam.
  • Looper thread factor = 8 ¸ 3 = 2.67 inches of looper thread per inch of seam.
  • Total needle thread consumed = factor 3 X 1.17yds = 3.51 yds
  • Total looper thread consumed = factor 2.67 X 1.17yds = 3.12 yds
  • Total Thread = 3.51 + 3.12 = 6.63 yards per seam.
  • Generally a 15 to 20% waste factor is added due to chaining-off, thread breaks, repairs, etc.
  • If a waste factor of 15% is selected then:
  • 6.63 yards/seam X 1.15 = 7.62 yards/seam including 15% waste factor.

Thread Consumption Formulas

Union Special Machine Company published a "Thread Consumption Booklet" that consists of a number of thread consumption formulas for various stitch types based on the stitch length and thickness of the seam. These mathematically derived consumption factors can be multiplied times the length of the seam to estimate the combined amount of top and bottom thread. On some overedge and coverstitch types it is necessary to also know the seam width or needle spacing to properly calculate the amount of thread consumed.

Example:
  • Stitch and seam: 401 SSa-1
  • Stitches per inch: 8
  • Thickness of the seam: .075 inches (measured with a micrometer)
  • Length of the seam: 42 inches or 1.17 yds.
Calculation (Consumption based on the mathematical equation):

C = 4 + 2ts
C = 4 + 2(.075 X 8) = 5.20

t = thickness of the seam
s = stitches per inch

1.17 yds X 5.20 = 6.08 yds / seam.
6.08 yds/seam X 1.15 = 7.00 yds per seam including a 15% waste factor.


Estimating Thread Consumption

As you can see from the Union Special chart, the more stitches per inch and the thickness of the seam impacts the amount of thread consumed. However, most heavy fabrics are sewn with fewer stitches per inch and most light fabrics are sewn with more stitches per inch. Therefore we have come up with the following estimates based on typical seam thickness and stitch length.

Example:
  1. Stitch & seam: 401 SSa-1
  2. Length of seam: 42 inches or 1.17 yards
  3. Fabric weight: Light weight
  4. Estimated Thread Consumption: 
    • 1.17 yds. X 5.0 (Ratio) = 5.85 yds. / seam
    • 5.85 yds/seam X 1.15 = 6.73 yds/seam, including a 15% waste factor
  5. Estimated needle thread: 6.73 X 40% = 2.69 yds
  6. Estimated looper thread: 6.73 X 60% = 4.04 yds

  1. Use lower estimated thread consumption numbers for light-weight fabrics or long stitch lengths.
  2. On the chainstitch construction, the amount of looper thread does not change unless the stitches per inch changes. On the other hand, the needle thread will change based on the thickness of the seam. Therefore, the percentage of needle thread goes up when the fabric gets heavier. Lt. Wt. (light weight) is generally like shirts and blouses; M. Wt. (medium weight) is generally like slacks or chinos; and H. Wt. (heavy weight) is generally like denim applications.

Average Thread Consumption Totals by Garment

The following is a list of sewn products and thread consumption totals based on thread consumption reports conducted by our Technical Service Department. These thread consumption figures include a 25% waste factor and are based on a typical garment construction.

Estimating Thread Cost

The thread cost can be estimated by multiplying the thread consumed times the cost of thread in the same units. For example:
Men’s Dress Shirt thread consumption:
  1. 25% waste factor = 131 yds.
  2. Average Cost of T-24 Poly Wrapped Core Thread:
    • $4.50 / 6000 yard cone
  3. Cost per yard $4,500:
    • 6000 yard cone = $.00075/yard
  4. Calculation:  
    • 131 yds./shirt X $.00075/yard = $.09825/shirt

Screen Printing


What is it...
Screen-printing is a process where a design, drawing or other format is converted to a film and the film is transferred to a screen. The number of screens for any design is based on the number of colors of the design. Links are then transferred through the screen to the garment in a proper order to achieve the desired result. The process involves exact pressures, specialized links and heat curing to result in a long lasting design.

 

 

 

 

 

Embroidery

Digitizing is a combination of artistic arrangement and computer process that takes a design, photo, drawing etc and converts it to an embroidery design. That design is then programmed into our computerized machines, to produce the desired result, an age-old process of needle and thread called embroidery. It was an art then and is still today.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

How to Take Measurements

 

General Tips

  1. You can view measurement photos to clarify certain measurements.

  2. When you wrap the measuring tape make sure it is not too tight or too loose. There should be no gap between the tape and body, but the tape should not sink into the skin at all.

  3. If you do want a very close fitting garment, just let us know in the comments. In that case accurate measurements are especially important.

Gold measurements are length-wise along or across one side of the body
Details About Measurements

  1. Height - From top of head to the floor (your standard height measurement). [See illustration]

  2. Neck - Around largest part of neck (base of neck). [See Photo | See illustration]

  3. Shoulder Width - Measure across upper back from end of one shoulder bone (top of arm) to the other shoulder bone (top of arm). It's important to stand with your usual posture and shoulder position. [See Photo | See illustration]

  4. Bust - Around the fullest part of bust. It is important to wear a bra to be accurate. [See Photo | See illustration]

  5. Waist - Around narrowest part of waist. [See Photo | See illustration]

  6. Belly - Around fullest part of belly. [See illustration]

  7. Hip - Around fullest part of hips. Please be sure you take the largest measurement in this area. [See illustration]

  8. Armhole - Around shoulder joint. [See Photo | See illustration]

  9. Sleeve Length - From shoulder tip down side of arm to prefered length of sleeves (with arm held straight). The shoulder tip is on top of the shoulder just near the arm. [See illustration]

  10. Around Upper Arm - Around the largest part of upper arm (bicep). [See illustration]

  11. Pants Inseam - From the crotch seam down inner leg to the floor (while barefoot). [See illustration]

  12. Garment Length - The length of the garment can be different for different designs and types of clothing. If you order more than one item, you may need to enter a different Garment Length for each. Here's how to measure Garment Length for a:
    1. Dress - From top of shoulder, down over the tip of one breast and down to the prefered length of the dress.
    2. Top (blouse or jacket) - From top of shoulder, down over the tip of one breast and down to the prefered length of the blouse or jacket. If the top is part of a set, there will also be a Pants/Skirt Length measurement for the bottom part.
    3. Pants or Skirt - Because ensembles (suits and sets) have both a top and bottom, the bottom part is a separate measurement. Please see R. Pants/Skirt Length above.

    [See illustration]

  13. Slit Length - Prefered length of slit of skirt or dress. [See illustration]

About Measurement Set Name

  1. Important - If you've already made a measurement set for a garment, and later you change the name of that set, you'll actually be starting a new set with the new name.

  2. You can have multiple measurement sets. Let's say you want to buy for your daughter Sara, but later you want to also buy for your son Allen. You can start a new set by entering the name Allen in the Name of Set field and then adding his measurements. Any of these names you enter will remain and you can choose them later.

  3. Many measurements are used for different kinds of garments. If you've entered measurements for one type of garment, those can be used for others without having to re-enter them. Whatever measurements apply will be loaded automatically when you choose that "Set Name".

About Measurement Units

  1. Important - If you want to change your units, you should change the name of your measurement set and select the other units. Until we can implement unit conversion safely it will be up to you to retake your measurements in the other units.

Lab dips are done to provide a visual aid on how a color will look when it is dyed. Your actual production sample will vary from the lab dip that is provided. Remember that the lab dip is produced in a beaker and is not an actual production run. It is not possible to lab dip enough fabric for a sample cap or garment. When the goods are dyed in a real production run, the conditions are dramatically different from the laboratory. Production will not begin on your fabric unless a lab dip is approved or the customer waives the lab dip process. Once a lab dip is approved, we will dye only to the lab dip approved. The original color swatch is no longer the target. Do NOT approve a lab dip that you would not be happy with as a production run.
