What is Fibre Morphology? | Microscopic View of Cotton Fibre | Molecular Structure of Cotton Fibre | Morphological Structure of Cotton Fibre | Chemical Structure of Fibre
The cotton fiber is a single plant cell. Its cross section is oval which is compared with the normal hexagonal plant cell. However, like all plant cell cotton has the following cells:
- Primary cell,
- Secondary cell,

All the above cotton cells have explained in the below:
The cuticle is the very outside or skin of the cotton fibre. It is consists of a waxy layer only a few molecular thick. The waxy nature of the cuticle enables it to adhere tenaciously to the primary wall of the fiber.
This type of cell is immediately underneath the cuticle is about 200nm thick. It is consists of very fine threads of cellulose which is known as fibrils.
Beneath the primary cell wall lays the secondary cell wall which forms the bulk of the fiber. Concentric layers of spiraling cellulosic fibers, not unlike the growth rings of trees, make up the secondary cell wall. The more thick of this layer means more matured fiber and thinner of this layer means more immature fiber.
The hollow canal running the length of the fiber is known as the lumen. Its walls are the innermost, concentric layers of spirals of the secondary cell wall. The lumen has once the central vacuole of the growing cotton fibres.

Morphology is the study of the size, shape and structure of a material or textile fibre and the relationship between these properties. The morphology of a textile fiber may be divided into following:
- The macro structure of textile fiber (length, thickness, fineness, color, translucency and lusture etc.)
- The macro structure of textile fiber (Microscopic longitudinal and cross sectional structure and appearance).

I want to to thank you for this wonderful read!! I certainly enjoyed every bit of it. I have got you book marked to look at new stuff you post…
After exploring a handful of the blog posts on your site, I truly appreciate your technique of blogging. I book marked it to my bookmark site list and will be checking back in the near future. Please check out my web site as well and let me know what you think.
