What is coarse wool used for?

Coarse wool nonwovens can be used to transport fish on ice to pack poultry after coating with superabsorbents to absorb their water and blood. Another possible application for coarse wool nonwovens is floor pads or bath mats. Because wool is hygroscopic and can absorb water, it is well suited for such applications either alone or combined with other natural fibres. Other applications of these coarse wools are in the form of coarse wool felted batts, which may be explored for energy-efficient civil construction, oil spills in the sea, sound absorption and thermal insulation panels for sustainable needs as well as simultaneous wool production. A felt handicraft and its applications are shown in Fig. 4.7.

What is wool made of?

Like all other protein fibres, wool is also derived from the animal hair. Wool is mainly used as a minor blend (up to 10%) with cotton to introduce special properties to the terry fabric. Raw wool contains a wide variety of impurities, which can account for between 30% and 70% of the total mass. The impurities consist of wool grease, secreted from the sebaceous glands in the skin; suint, produced from the sweat gland; dirt and sand. Wool grease consists chiefly of esters, formed from a combination of sterols and aliphatic alcohols with fatty acids. Suints consist primarily of the potassium salts of organic acids.

How is wool determined?

Wool is usually harvested from sheep by annual shearing. Consequently, fibre length is determined largely by the rate of growth , which in turn depends on both genetic and environmental factors. Typical merino fibres are 50–125 mm long. They have irregular crimp (curvature), with the finer fibre generally showing lower growth rates and higher crimp. The fibre surface is rough due to the outer layer of overlapping cuticle cells. By far the most important dimension is the fibre diameter. Wool fibres exhibit a range of diameters, which like fibre length are dependent on both genetics and environment. Coarse wool fibres (25–70 μm diameter) are used in carpets, whereas fine merino fibres (10–25 μm) are used in apparels because of their soft texture. Fibres from an individual sheep also exhibit a range of diameters. The mean diameter is the prime dictator of price; however, the distribution of diameters is also important.

What is the diameter of a microcapsule?

The ability of textile materials to carry bioactive ingredients can be used to micropackage cosmetic ingredients on to textiles. Microcapsules suitable for cosmetotextiles have mean diameters typically ranging from 1 to 10 μm. This compares to a range of 5–30 μm for a single textile fiber, from about 5 μm for microfibers to about 30 μm for coarse wool. Microcapsules can be modified in size, mechanical robustness, and permeability to customize the release profile to fit the intended functionality best.

What are the structures of keratin?

Keratin fibres, such as wool, alpaca and human hair , have complex structures and morphologies. The fibre surface is covered with scales ( Fig. 6.2 ), which are collectively referred to as cuticles. The cuticle cells are attached at the root end and they point towards the tip end of the fibre, like tiles on a roof. Enclosed by the scales is the main body of the fibre, which is an assembly of closely packed cortical cells, known as the cortex. It accounts for approximately 90% by weight of a wool fibre ( Anderson et al. 1972 ). There are three types of cortical cells: ortho-cortical, meso-cortical and para-cortical cells. Intercellular adhesion is provided by the cell membrane complex. Wool fibres have a bilateral structure with an ortho-cortex on one side and a para-cortex on the other. The ortho-cortex and para-cortex have slightly different compositions, structures, and properties, and the radially asymmetric cortical properties result in the unique property of natural crimp for wool ( Morton and Hearle 1993 ). Fibre crimp, with para-cortical cell on the inside of the crimp and ortho-cortical cell on the outside, causes the major axis of elliptical cross-section fibre to rotate along the fibre length, which may influence the evaluation of some fibre properties such as the fibre flexural rigidity. A loosely packed porous region called the medulla is located near the centre of the fibre and is usually found in coarse wool and some hair fibres. Each of the morphological components contains various structural elements which affect the fibre’s fatigue properties.

What is the purpose of a baselayer?

They should not be too thick, as their primary purpose is to keep the body dry; it is not to insulate.

What is the outer surface of animal fibers?

The outer surface of fibers consists of cuticle cells (scales), which overlap like tiles of a roof to give the well-known range of distinctive surface structures of animal fibers ( Fig. 3.5; Dobb et al., 1961 ). The thickness of the cuticle ranges from 1 to 2 scales for fine fibers such as wool, cashmere, and mohair, up to 8–10 cuticle cells for coarser fibers such as goat guard hair. The cuticle constitutes 10%–20% of the weight of a fiber and provides the tough protective layer for the 80%–90% bulk of the fiber, which is composed of long, spindle-shaped cortical cells and medulla cells when these are present.
