Things to Know About a Stubb Yarn Balance

The Stubb yarn balance is also known as a pocket balance. It is used for determining the weft yarns and the count of warp which is extracted from a small piece of fabric. 

A yarn balance is known as a yarn counting system which is helpful for the textile industry. It helps to determine the characteristics of yarn and how it should be treated during the manufacturing process. 

There are various methods of finding the yarn count of a fabric material and a Stubb yarn balance is one. In this article, we will go through all the required topics about a Stubb yarn balance.  

What is a Stubb Yarn Balance? 

A Stubb yarn balance is like a beesley balance and it is used for finding the count of a fabric sample. It works on the basics of fixed weight and fixed length and you have to take multiple counts to ensure that there is no space for human error. The number of fixed-weight yarn is the count of the yarn.

The yarn count measurement system consists of two categories – analytical system and instrumental system. Under the instrumental system, Stubb yarn count takes its place as it requires an instrument to take the values of the yarn. Other instrumental systems include quadrant, wrap reel, and the Beesley balance.  

How to Use a Stubb Yarn Balance?

Here is a short description of how to use a Stubb yarn balance. Even though we have tried to cover all the parts and utilities of the Stubb yarn balance, it is best to get a first-hand experience to truly understand its mechanism. 

  1. Take a sample fabric of your choice. 
  2. Suspend it at one end of the beam and on the other end, suspend the weight hooks. 
  3. Use a template to cut the yarn up to a fixed length. 
  4. When you are using different materials, also use a different variety of weight hooks. 
  5. Select the material and its respective weight hook and suspend them on either side. 
  6. Ensure both of them are balanced to get the correct result. 
  7. The number of threads needed to balance the beam gives the yarn count of the sample in question. 
  8. To ensure that this task is successful and there are minimal errors, it is best to carry out the task using various fabric samples. 
  9. While keeping the length of all the samples fixed, create a chart to document all the measurements.  

Precautions to Take. 

  1. Cut the fabric carefully along the template. 
  2. Samples should be kept at a standard testing temperature before the test begins. 
  3. Be gentle while removing the yarn from the fabric before the test. 
  4. While noting the readings, be careful with the numbers.  

Final Words:

The Stubb yarn balance is an easy instrument to use if you are accustomed to various textile types of machinery. There is no mechanism that goes out of order since the tool is very self-explanatory. The Stubb yarn balance can be used in weaving laboratories or testing to find the count of weft yarns and warp throughout the cloth analysis.
