Specific Gravity
Specific gravity is a term used in the textile industry to describe the density of a material relative to the density of water. It is an important property of textiles, as it can affect the performance and durability of fabrics in a variety of ways.

Specific gravity is expressed as a ratio of the weight of a material to the weight of an equal volume of water. For example, if a material has a specific gravity of 1.5, it is 1.5 times as dense as water. Materials with a specific gravity less than 1 are less dense than water, while those with a specific gravity greater than 1 are more dense than water.

In textiles, specific gravity is often used to determine the fiber content of a fabric. Different types of fibers have different specific gravities, so by measuring the specific gravity of a fabric, it is possible to estimate the proportion of each type of fiber present.

Specific gravity can also affect the performance of fabrics in other ways. For example, fabrics with a higher specific gravity tend to be more durable and resistant to abrasion, as they are more dense and less likely to tear or wear down over time. Conversely, fabrics with a lower specific gravity may be more lightweight and breathable, but may also be less durable.

Another factor that can affect specific gravity in textiles is the presence of moisture. When textiles absorb water, they become heavier and their specific gravity increases. This can affect the way the fabric drapes and behaves, as well as its durability and other properties.

There are several methods for measuring specific gravity in textiles, including the use of specialized instruments such as densitometers or pycnometers. These methods typically involve weighing a sample of the material and comparing it to the weight of an equal volume of water.

Overall, specific gravity is an important property to consider when working with textiles, as it can affect the performance, durability, and other characteristics of fabrics. By understanding how specific gravity works and how it can be measured, textile professionals can make more informed decisions when selecting materials for a particular application.
Specific Gravity
The density of a material divided by the density of water. Expressed as a number greater than 0. Materials with specific gravity less than 1.00 will float and materials with specific gravity greater than 1.00 will sink in water.
