Basic weaving processes…

Posted in General Information, Bed Linen

We ended off last time with our discussion on percale fabrics and today we’ll be looking at the weaving processes.

In general you will find that a percale weave is much tighter than other fabric weaves.  Specifically we’ll discuss the Cotton Manufacturing Process.

Firstly, cotton fibres are harvested from cotton plants. (Various plants e.g Egytpian cotton plants or up-land cotton). These fibres then undergo a lot of cleaning and sorting processes namely:

The Ginning Process: Fibres are sorted into different catogories e.g. length, strength or thickness while husk and leaves and seeds are also removed as far as possible.

Next is Blending: Various grades of cotton is blended during this process to ensure that a uniform result is achieved on the final yarn/ fabric.

Following this is the Carding & Combing: During these processes, fibres are cleaned even further (remove rest of seeds and husk etc) and fibres are aligned (short ones removed) ready for further processing. This has huge impact on the final quality and strength of the yarn used for weaving.

Next is Spinning: The fibres are twisted together to produce yarns for weaving. Yarns are the building blocks of fabric and should thus be of good quality to ensure good quality fabric. This process also impacts greatly on the final yarn.

Now we reach weaving: The yarns produced during spinning are used in the warp (length of fabric) and weft (picks inserted across) of the fabric. Weaving is a technique where the warp and weft are intertwined to form fabric. A loom is used to weave the fabric on. It keeps the warp threads in place whilst the weft threads are woven through.

There are three basic weaving patterns namely: Plain weave, twill weave and satin (sateen) weave. We will talk about these next time. 

Please let me know whether this all makes sense and whether you want more information on these processes..

Have a good day!
