The study of human skeletal remains and burial customs provides important information concerning the demography, nutrition, and health status of past populations; they may also provide data about social identity, social organisation, ideology, rituals, religion, and symbolism (Larsen, , Pearson, , Walker, ).Treatment of the corpse after death varied considerably in Cited by:

The hair like fibres, are held together by a gummy substance known as pectin. Linen is composed of 70 percent cellulose, and 30 percent pectin, woody tissue, ash and moisture.

Here, I have written about physical and chemical properties of cotton fiber. Physical Properties of Cotton: Physical properties of cotton fibers are given below: Color: The color of cotton fiber could be white, creamy white, bluish white, yellowish white or grey.

Tensile Strength: Cotton is moderately strong fiber. It has a tenacity of gm/den. Chemical structure and properties of cotton 27 intensities decreased rapidly from 3 dpa to 10 dpa, the cm –1 band, also observed in the spectrum of 3-dpa fibers, increased : You-Lo Hsieh.

Feeding, diet and the general care of children Philadelphia: F. Davis Co., Bell, Robert. Fabric chemical testing is a task requiring a good understanding of chemistry as well as of textiles.

Because many textile chemicals are applied to substrates based on the affinities between the textile material and the chemical, conducting a fiber identification first can often provide a good direction towards the following dye/chemical by: 1.

Scope. These test methods cover procedures for the determination of the fiber blend composition of mixtures of the fibers listed in Procedures for quantitative estimation of the amount of moisture and certain nonfibrous materials in textiles are also described, for use in the analysis of mixtures, but these are not the primary methods for the determination of moisture content for.

In this work, the surface chemistry of cotton and linen fabrics is analyzed with Electron Spectroscopy for Chemical Analysis (ESCA), with special emphasis on the location of the waxes and lignin.

Chemical separation has resulted in successful laboratory results, but at times, fiber properties are less satisfactory than those from other methods. Efforts are reported to be still underway to assess physical and chemical methods to separate fiber.

The use of enzymes, focusing on pectinases, also has been researched for some time [37, Cited by: Chemical separation has resulted in successful laboratory results, but at times, fiber properties are less satisfactory than those from other methods.

Efforts are reported to be still underway to assess physical and chemical methods to separate fiber. The use of enzymes, focusing on pectinases, also has been researched for some time [37, Linen fabric has a number of properties, that makes it highly useful for various applications, in industry, in home furnishings and apparels.

We are discussing in details the linen properties below: Linen Properties. Strength: An important property of linen is its strength.

Linen is a durable fiber, as is two-three times as strong as cotton.
