Does your manufacturing company have control over fabric yield? Although not always monitored, this information has a major impact on costs, as waste is one of the main problems within the textile industry and knowing the yield prevents this waste from occurring.
By knowing data on fabric yields, it is possible to devise strategies that allow better use and obtain a more profitable return on production. Do you want to understand more about the topic and discover how to calculate fabric yield? Check out the article below!
What is the yield of fabrics and knitwear?
The yield of fabrics and knitwear is information expressed through the assessment of the quantity of fabrics that can be transformed into pieces. It makes it possible to calculate costs in a way that, when taking other values into consideration, it is possible to obtain exactly what value is used to produce each part.

How to calculate the yield of fabrics and knits?
The first step in carrying out the calculation is to identify the characteristics of the fabrics that will be used. This information helps guide important decisions, even when choosing the thread and needle used in sewing.
The weight is one of the most important pieces of information and is usually indicated on the material label. If not, it can be calculated using the formula for the relationship between the weight of the fabric and the square meter.
Using weight, it will be possible to classify the fabric as light, medium or heavy, see the table below:
With this information in hand, it will be possible to calculate the linear and technical yield. Check out more about how and why to do this below.
Linear Yield
Linear yield (RL) is the yield per m² of fabric in each linear meter and considers the width of the fabric. It is calculated with the following formula:
RL = 1 x 1000
total width x weight
It is worth mentioning that, if the fabric is tubular, you need to multiply the total width by 2.
Technical performance
Technical yield is information about the area available in each kilogram of fabric and is calculated using the formula:
RT = 1 x 1000
grammage
Did you see how simple the process is? And it can bring excellent changes to clothing processes.

Benefits of knowing your income
Although the calculation seems to be just another step and represents a new task for production, it can provide several benefits that are worth it. To begin with, with the calculations in hand it is possible to know the exact amount of fabric to be purchased. This saves money and avoids costs associated with excessive purchases of fabrics and scraps.
Another point is the possibility of knowing exactly what the productive capacity of the stock is with current inputs. Because of this, one of the advantages is predictability, which prevents production stops due to lack of inputs. It is also possible to better control the quality of purchased inputs, providing an improvement in quality control and avoiding the manufacture of second-quality parts.
There is already equipment that facilitates this process, such as the Mesh and Fabric Reviewer. It has several functions, including collecting data such as meters of usable area, grammage and width. The process is simpler and more automated, being carried out much faster and more effectively than traditional inspection.
In addition to fabric yield, other problems can impact production costs. If your intention is to avoid them and ensure as much predictability and profitability as possible, take advantage and check out the common mistakes when receiving and evaluating fabrics in manufacturing right now.!
