When choosing the right needle density for your drum carder, it is important to know what types of fibers you want to process. Needle density is measured in teeth per inch (TPI) and determines how fine or coarse the wool is carded. Here is an overview of the different needle densities and their best applications:
120 TPI – For Fine Wool
The 120 TPI carding cloth is specially designed for processing fine wools such as merino or alpaca. This high needle density allows the fine fibers to be carded without breaking, creating a very fine and uniform bat. This is the best choice when working with luxurious, soft wool that requires extra care and precision. This carding cloth is not suitable for coarse wool. Because of the high needle density, you damage the fibers of coarse wool.
72 TPI – The Versatile Option
With a needle density of 72 TPI, you can do almost anything. This is the most versatile option and works great for most sheep’s wool. It offers a good balance between carding fine and coarse fibers, allowing you to work with a wide range of wool types. This carding hardware is also suitable if you occasionally card merino or alpaca wool.
54 TPI – For Coarse Wool
The 54 TPI carding cloth is perfect for carding coarse wools. If you are working with rougher, thicker fibers, this needle density is the best option. The lower needle density allows the coarse fibers to separate well without too much resistance, resulting in a thick, firm bat.
Conclusion
For those looking for a versatile drum carder that can work with a wide range of wool types, 72 TPI is the best choice. With 72 TPI carding cloth, you can process both fine and slightly coarser fibers with good results. However, if you specifically work with very fine or very coarse fibers, consider the respective 120 TPI or 54 TPI options for optimal performance. Still have questions? Feel free to contact us.
