Lycra yarn, also known as spandex or elastane, is a synthetic fiber known for its exceptional elasticity and ability to stretch, making it ideal for activewear and form-fitting garments. Core yarn, on the other hand, refers to a yarn that has a central core of one fiber (often elastane) surrounded by another fiber, providing both strength and stretch while maintaining the appearance of the outer material. Essentially, Lycra is a type of fiber, whereas core yarn is a construction method that incorporates elastic fibers for added functionality.

How do you calculate lycra content in a core yarn?
lycra %ge= yarn count*lycra denier/5315*lycra draft
How do lycra percentag denir yarn count calculate?
To calculate the Lycra percentage in a yarn, you first need to determine the total weight of the yarn and the weight of the Lycra component. The Lycra percentage is calculated by dividing the weight of the Lycra by the total weight of the yarn, then multiplying by 100. For example, if you have 10 grams of Lycra in a 100-gram yarn, the calculation would be (10g / 100g) × 100 = 10% Lycra. Yarn count, on the other hand, is typically expressed in terms of weight per unit length, and can be calculated using specific formulas depending on the measurement system (e.g., metric or imperial) used.
