Basic Consumption on Knit Items Calculator

What is the Basic Consumption on Knit Items?

Basic Consumption on knit items, often abbreviated as CPD (Consumption per Dozen), is a measure used in the textile industry to determine the amount of fabric required for producing a specific quantity of knit items. It calculates the weight of fabric needed to produce one dozen units of a knit item based on its length, width, and GSM (grams per square meter).

Knit Items Consumption Calculator

Formula:

Consumption per Dozen, CPD= L×W× GSM × 12 /1,00,00,000  kg

For Calculation, we have to follow MKS System (MKS: Meter Kilogram Second) or CGS System (CGS: Centimeter Gram Second).

How to Use the Basic Consumption on Knit Items Calculator?

1. Enter the length of the knit item in meters into the “Length” field.
2. Enter the width of the knit item in meters into the “Width” field.
3. Enter the GSM (grams per square meter) of the knit item into the “GSM” field.
4. Click the “Calculate” button to obtain the consumption per dozen (CPD) in kilograms.
5. Click the “Refresh” button to clear all fields and start over.

Neck Height 4 cm (2+2).

Sleeve Length 25 cm

← Bottom Hem (Seam Allowance=2 cm

+ Sewing Allowance=1 cm)

Basic Consumption on Knit items:

Men’s T-Shirt

Points to be Considered:

A. Measurement:

1) HPSL (High Point Shoulder Length)

2) Chest or 1⁄2 chest

3) Armhole

4) Sleeve Length

B. Seam Allowance + Sewing Allowances:

C. Fabric GSM: 165~170 GSM

• Consumption per Dozen, CPD= L×W× GSM × 12 /1,00,00,000  kg

=L×W× GSM × 12 /100 × 100 × 1,000

=L × (1⁄2 Chest × 2) xGSM x12/1,00,00,000 kg

For Calculation we have to follow MKS System (MKS: Meter Kilogram Second) or CGS System (CGS: Centimeter Gram Second).

CPD (Consumption Per Dozen) for Body:

• Length = 72 cm (HPSL) + 5 cm [ In Bottom Hem Sewing Allowance = 3 cm ( Seam Allowance = 2 cm + Sewing Allowance = 1 cm ) + In Neck (Rib) Sewing Allowance = 2 cm] = 77 cm
• Width = 100 cm (Chest) +  6 cm [In Side Seam Sewing Allowance = 3 cm (1.5 cm + 1.5 cm) × 2]= 106 cm or [50 cm (1⁄2 Chest) + 3 cm {In Side Seam Sewing Allowance (1.5 cm + 1.5 cm)}] × 2 = 106 cm

CPD = L×W× GSM x 12 /1,00,00,000 kg

= 77 x 106 x 170 x 12 /1,00,00,000 kg

= 1.67 kg (Body)

CPD (Consumption Per Dozen) for Sleeve:

Sleeve Hem (Seam Allowance 2 cm →

+ Sewing Allowance = 1 cm)

Side Seam

(Sewing Allowance = 1.5 cm)

Sleeve

Side Seam

(Sewing Allowance = 1.5 cm)

Armhole 40 cm (20+20) (Sewing Allowance = 2 cm)

Sleeve Length 25 cm

Application of Basic Consumption on Knit Items:

The CPD calculation is essential for textile manufacturers to accurately estimate the amount of fabric required for producing a certain quantity of knit items such as t-shirts, sweaters, and other garments. By knowing the CPD, manufacturers can optimize their fabric usage, reduce wastage, and streamline production processes to meet demand efficiently.
