Characteristics of Wool Fiber:

http://textilerawmaterial.blogspot.com/1. Wool is the natural protein fiber obtained from sheep where cashmere from goats, mohair from goats, angora from rabbits and other wool from camels.
2. It is very fine, soft and highly elastic fiber which contains up to 70 percent unnecessary material other than protein or fiber portion.
3.It is structurally very complex fiber and composed essentially of three tissues, the cuticle, the cortex and the medulla.
4. Usually its length is 1 to 14 inch and comparatively has low strength than other natural textile fibers.
5. Scaling and crimp of wool fiber makes it easier to spin the fleece by helping the individual fibers attach to each other.
6. Due to crimp, wool fabrics have a greater bulk than other other textiles, and retain air which causes the product to retain heat, thus it is suitable for making warm cloth as well.
7. Crimp of wool fiber as like as the fineness of the fiber such as merino(fine wool) have up to 100 crimps and Karakul(coarse wool) may have as few as 1 to 2 crimps.
8. This fibers are hydrophilic it means theyr eadily absorb moisture but are not hollow, standard Moisture Regain of wool is 15 percent.
9. Wool is normally a creamy white fiber, although some breeds of sheep produce natural colors, such as black, brown, silver, and random mixes.
10. Wool fibers are affected by fire at higher temperature than cotton as well as many manufactured fibers.


Quality of Wool Fiber:

Quality of wool fiber depends on fiber diameter, crimp, productivity, color and staple length. For better price fiber fineness is single most important characteristic. According to the grading of wool, merino wool is typically 3-5 inches in length and is super fine as its diameter is between 12 to 24 microns. The most valuable and finest wool comes from Merino Hoiggets. Other sheep wools which are collected from meat producing sheep are typically more coarse and have a short staple length.


Uses:

1. Wool is very fine, soft fiber as it is used about 60 percent in the apparel industry. In addition to apparel manufacturing, it is being used for blanks, rugs, carpets, felt, insulating material and domestic purpose.

2. Wool fiber is typically used to cover apparel diapers.

3. Wool fibers are externally hydrophobic and internally hygroscopic in nature, thus it can be used to cover a wet diaper while inhibiting working as a result outer clothes remain dry.

4. It is used to make underwear because it more readily absorbs the moisture that prevents heat and sweat rashes.

5. The most finest merino wool is used to produce infant wear as well.a

Wool is a animal fiber of outstanding importance. It is a protein fiber collecting from fur of sheep. This protein fiber consists of C, H, O, N, S etc. Wool is very fine, elastic fiber. Hair of some animals fibers can be considered as textile fiber but wool has special features which distinguish it from other hairs but which renders it supremely valuable as a textile fiber.  These differences are of a physical nature and the basic tissues and chemical structure of all animal hairs, including wool, are similar.

The wool fiber is complex in structure and composed essentially of three tissues, the cuticle, the cortex and the medulla. Each of these, however is further subdivided by tissue differentiation. A purely diagrammatic illustration of the structure of a non-medullate fiber has shown in image.



The epi-cuticle and exo-cuticles of wool contain a high proportion of sulpher with many cystine cross linkages giving them a high measure of resistance to biological and chemical attack. The endo-cuticle of the other hand is somewhat less resistant. There are inter-cellular membranes which act as a concent holding the cuticle to the adjacent tissues. It is seen from the structural image that the cortical cells are composed of macro-fibrils, each of which contain a number of micro-fibrils lying parallel with each other.
