Fabric choice is crucial for product quality, comfort, and performance. Here is some knowledge you should understand when sourcing fabrics:
- Fabric Weight: Consider the weight of each garment being designed, as it can affect draping and fit. Fabric weight is listed in grams per square meter (GSM), and examples of common weights for different types of knitwear are provided: 200-300 GSM for activewear, 180-250 GSM for lounge pants, 130-180 GSM for standard t-shirts, and 130 GSM or less for lightweight t-shirts. These are guidelines and may vary for your clothing line.
- Fabric Lab Testing: This is a process of testing the physical and chemical properties of a fabric to ensure that it meets the required quality and safety standards. There are several different types of fabric lab testing, including physical testing (such as tensile strength and tear resistance), chemical testing (such as pH and formaldehyde content), and performance testing (such as abrasion resistance and moisture management). This can help to identify any potential issues or defects in the fabric that may affect its performance or appearance.
- Fabric Construction: The process of converting yarns or fibers into fabric and determining its characteristics through the materials and methods used, such as weaving or knitting.
- Fabric Care Instructions: The instructions provide recommendations for washing and caring for a specific fabric based on its content and construction. Different fibers may require different care, such as avoiding high heat or dry cleaning. These instructions are provided to ensure the longevity of your fabric.
