Lycra Percentage Formula

The formula for calculating Lycra percentage is derived from key parameters in textile manufacturing. By inputting machine diameter, machine gauge, yarn count, machine S.L, and Lycra C.M into the Lycra Percentage Calculator, you can quickly determine the percentage of Lycra in your fabric.

Other lycra percentage in yarn shortcuts you can use:

1. Lycra Percentage = [(Lycra denier/ lycra draft)/ Resultant yarn denier] × 100%
2. Lycra Percentage = [(Lycra denier/ lycra draft)/5314.9/ Resultant yarn Ne] × 100%
3. Lycra Percentage = [(yarn count (Ne) × lycra denier)/(5314.9 × lycra draft)] × 100℅.

Lycra Percentage Calculation

1. Needle Count Calculation

The total number of needles in the knitting machine is calculated as:

Needle Count =Machine Diameter×Machine Gauge×π

• Machine Diameter: Diameter of the circular knitting machine (in inches).
• Machine Gauge: Number of needles per inch in the machine.
• π (Pi) = 3.1416

This gives the total number of needles available for knitting.

2. Lycra Stitch Length (LycraSL) Calculation

The Lycra stitch length per loop is calculated as:

• Lycra C.M: Lycra consumption per centimeter.
• Needle Count: Total needles in the machine (from Step 1).
• 10: Conversion factor (since Lycra C.M is given per centimeter, and we need per 10 cm).

This determines how much Lycra is consumed per stitch.

3. Lycra Count Calculation

Lycra count is usually calculated based on the denier (D) of Lycra yarn. For example, if 20 Denier Lycra is used, the Lycra count is:

This represents the count of Lycra in textile calculations.

4. Lycra Percentage Calculation

Finally, the Lycra percentage in fabric is given by:

This formula determines how much Lycra is present in the fabric as a percentage of the total material.

Example Calculation

Let’s assume the following values:

• Machine Diameter = 30 inches
• Machine Gauge = 28
• Lycra C.M = 2.5
• Lycra Denier = 20

Step 1: Needle Calculation

Needle Count=30×28×3.1416=2638.94Needle Count=30×28×3.1416=2638.94

Step 2: Lycra Stitch Length Calculation

LycraSL=2.5×102638.94=252638.94=0.00947LycraSL=2638.942.5×10​=2638.9425​=0.00947

Step 3: Lycra Count Calculation

Lycra Count=531520=265.75Lycra Count=205315​=265.75

Step 4: Lycra Percentage Calculation

Lycra Percentage=(0.00947265.75)×100=0.00356%Lycra Percentage=(265.750.00947​)×100=0.00356%

Thus, the Lycra percentage in the fabric is approximately 0.00356%.
