Preparing raw wool for carding is an essential step in the process of turning a raw fleece into a usable fiber for spinning, felting, or other textile applications. Carding is a process that aligns the fibers in the same direction, producing a rope-like strand called a sliver, which can then be spun into yarn. However, before carding can take place, the raw wool must be properly prepared to ensure that it is clean, free of debris, and in a state that allows for efficient carding. In this article, we will explore the steps involved in preparing raw wool for carding.
Sorting and Skirting the Fleece
The first step in preparing raw wool for carding is to sort and skirt the fleece. This involves removing any debris, dirt, or damaged fibers from the fleece, as well as separating the different grades of wool. Sorting and skirting can be done by hand or using a mechanical sorter.
Hand Sorting and Skirting
Hand sorting and skirting involves manually inspecting the fleece and removing any debris, dirt, or damaged fibers. This process can be time-consuming, but it allows for a more thorough inspection of the fleece and can help to identify any potential problems.
To hand sort and skirt a fleece, start by laying it out on a flat surface and inspecting it for any visible debris or damage. Remove any loose dirt or debris, and then begin to separate the different grades of wool. This can be done by gently pulling the fibers apart and separating them into different piles.
Identifying Different Grades of Wool
When sorting and skirting a fleece, it’s essential to identify the different grades of wool. The grade of wool is determined by its quality, color, and fiber length. The different grades of wool are:
- Prime wool: This is the highest grade of wool and comes from the back and sides of the sheep. It is typically long, fine, and white.
- Second-grade wool: This grade of wool comes from the neck and belly of the sheep. It is typically shorter and coarser than prime wool.
- Third-grade wool: This grade of wool comes from the legs and tail of the sheep. It is typically the shortest and coarsest of all.
Cleaning the Fleece
Once the fleece has been sorted and skirted, it’s essential to clean it thoroughly to remove any dirt, oil, or other impurities. There are several methods for cleaning a fleece, including hand washing, machine washing, and using a fleece cleaning product.
