Calculating the correct amount of fabric for the manufacture of short sleeve T-shirts using efficient formulas is described in this article. To produce a garment, it is necessary to consume a certain amount of fabric. This is known as fabric consumption. A garment’s fabric represents about 70% of its total cost and is therefore considered the most important factor in the cost of the product. The business’s success depends on the ability to control this aspect correctly. A good marker is one of many things that need to be used, but you need to make sure that the fabric is utilized to the maximum extent possible. The merchandiser is responsible for the costing, which is the core of product merchandising, and the responsibility for fabric consumption is in the hands of the merchandiser. As part of the sampling process, the merchandiser will quote the cost of the garment. Thus, merchandisers must know how to calculate fabric consumption based on the calculations. In this article, we will explore how to calculate the consumption of a basic short sleeve T-shirt by using consumption calculations.

Why are T-Shirts Calculated by Weight?

The consumption of T-shirts will be calculated based on the weight of each shirt. As we all know, knitted fabrics can be stretched easily in length and width directions because knitted fabrics get stretched easily in both directions. In the case of knitted fabrics, the width of the knitted fabric is reduced when the fabric is elaborated lengthwise. It is also possible for a supplier to measure knit fabric by stretching it if we buy knit fabric in length from the supplier. When we open the fabric at our factory later on, we will see that the actual length of the fabric is shorter than the length of the fabric we purchased earlier. It is because when the fabric is relaxed, the pressure is released from the fabric. Therefore, it is impossible to measure the knit’s fabric precisely in terms of length. That’s why we will buy knit fabric in weight to get the most out of it. This is why we make a weighted calculation of the fabric consumption for a T-shirt.

Fabric consumption is an essential calculation for a merchandiser in the apparel industry for several reasons:

  1. Costing: Accurate fabric consumption calculation is essential for determining the cost of production. The fabric cost is a significant portion of the total production cost of a garment, and an incorrect calculation of fabric consumption can result in either underestimation or overestimation of the fabric required, leading to a wrong calculation of production costs.
  2. Production planning: Fabric consumption calculation also helps in production planning. It allows the merchandiser to estimate the fabric needed for a particular style, which helps determine the fabric requirements for the production order.
  3. Order placement: When placing an order with the supplier, the merchandiser must provide accurate fabric consumption calculations to ensure the supplier can provide the correct amount of fabric needed for production.
  4. Fabric utilization: An accurate calculation of fabric consumption can help optimize fabric use by reducing wastage. By knowing the exact amount of fabric needed, the merchandiser can plan the marker (a layout of pattern pieces on the fabric) effectively to minimize fabric wastage during the cutting process.

In summary, fabric consumption calculation is crucial for a merchandiser in the apparel industry as it helps determine the cost of production, production planning, order placement, and fabric utilization, which all contribute to the overall efficiency and profitability of the garment manufacturing process. Here I try my best to show the fabric consumption calculation in easy way.

The textile industry is constantly striving to optimize its production processes and increase efficiency, especially when it comes to fabric consumption. To achieve this goal, fabric calculation and consumption techniques have been refined and improved over the years. Today, there are numerous formulas and methods available for calculating fabric consumption in the manufacturing of basic short sleeve t-shirts. Global rankings have been developed to highlight the most efficient and effective formulas for fabric consumption calculation in the production of these popular apparel items. By utilizing these top-ranking formulas, apparel manufacturers can not only reduce fabric waste but also improve their overall production efficiency and profitability. With ongoing efforts to refine and optimize fabric calculation techniques, the textile industry can continue to make strides towards more sustainable and profitable manufacturing practices.
