Picks per Inch (PPI)

Definition:

Picks per Inch (PPI) is a textile measurement that indicates the number of weft threads (or “picks”) woven into one inch of fabric. In the context of velvet manufacturing at MTG Velvet, PPI refers to the horizontal threads interlaced through the vertical warp, contributing to the fabric’s density, texture, and overall plushness. For velvet, a fabric renowned for its soft pile, PPI is essential in shaping both the base structure and the luxurious surface that defines our products.

How PPI is Measured:

PPI is determined by counting the weft threads across a one-inch width of fabric, often using a magnifying tool like a pick glass for accuracy. In velvet production, this count is assessed post-weaving, as the weft threads not only form the base fabric but also interact with the pile—whether cut or looped—to create the final texture. At MTG Velvet, we meticulously control PPI during the weaving process to ensure consistency and quality in every yard of fabric.

Role in Velvet Manufacturing:

At MTG Velvet, PPI is a vital factor in crafting velvet’s distinctive character. A higher PPI—such as 80 or more weft threads per inch—produces a tightly woven fabric, resulting in a smooth, dense base that supports a fine, even pile, ideal for lightweight apparel or elegant curtains. A lower PPI, like 40–60, creates a looser weave, often used for thicker, more substantial velvets suited to upholstery or heavy drapes. The balance between PPI and pile density defines the fabric’s softness and durability.

Factors Influencing PPI:

Several elements affect PPI in velvet production. The thickness of the weft yarn, measured in units like denier or tex, determines how many threads can fit per inch—thicker yarns reduce PPI, while finer ones increase it. Loom settings, including the speed and tension of weaving, also play a role. Additionally, the pile’s construction influences PPI, as a denser pile may require a tighter weft to anchor it securely. At MTG Velvet, we fine-tune these factors to align PPI with each fabric’s intended purpose.

PPI and Fabric Quality:

A higher PPI often suggests a smoother, more refined fabric, but quality hinges on application. For example, a high-PPI velvet might excel in a flowing dress for its sleek finish, while a lower-PPI velvet could shine in a plush sofa cover for its heft and resilience. PPI complements ends per inch (EPI)—the warp thread count—to determine the weave’s tightness, making it a key indicator of velvet’s structural finesse.

Comparing PPI to Other Metrics:

PPI pairs with metrics like GSM (Grams per Square Meter) and thread count. While GSM measures total weight, including the pile, PPI focuses on the weft’s contribution to density. Thread count combines PPI and EPI for a broader picture, but PPI alone highlights the horizontal weave’s impact on texture. This precision is critical at MTG Velvet, where every thread enhances the fabric’s appeal.

Practical Use at MTG Velvet:

Though not always highlighted in product listings, PPI underpins the quality of our velvets. A high-PPI fabric might be praised for its delicate sheen, while a lower-PPI option could emphasize rugged luxury. Understanding PPI helps customers grasp the artistry behind MTG Velvet’s offerings.

Conclusion:

Picks per Inch (PPI) is a cornerstone of velvet’s creation, weaving together function and beauty. At MTG Velvet, it guides our craft, ensuring each fabric—from airy elegance to sturdy opulence—reflects our commitment to excellence. PPI isn’t just a number; it’s the heartbeat of our velvet’s texture and soul.
