What is moisture regain (R)?

It is defined as the weight of water in a material expressed a percentage of the oven dry weight of the material. Moisture Regain (R) = Weight of Water / Oven dry weight of the material x 100 The temperature of the oven dryer should be 105* ± 3*c. The water partile should be removed and time is 2 hours.

What is moisture regain in textiles?

Moisture regain is defined as the percentage of water present in a textile material of oven dry weight. The percentage of moisture in a textile material brought into equilibrium with a standard atmosphere after partial drying, calculated as a percentage of the moisture-free weight.

What is meant by moisture content?

Moisture content is defined as the weight of water in the material expressed as a percentage of the total weight. Standard Moisture Regain: The moisture absorbed by a particular weight sample in the standard atmosphere after treating at 105±3 oC is called Standard Moisture Regain.

How to calculate moisture regain in oven dryer?

Moisture Regain (R) = Weight of Water / Oven dry weight of the material x 100. The temperature of the oven dryer should be 105* ± 3*c. The water partile should be removed and time is 2 hours. For Example: Initial weight of sample = 10grms.

What is the moisture regain?

A fiber's moisture regain is defined as "the amount of moisture that a material is able to reabsorb after its [sic] has been dried". It is expressed as a weight/weight percentage (w/w%) of water in a fiber versus the fiber's dry weight. Different textile fibers have distinct moisture regain.

What is standard regain?

When the moisture present in a textile material is calculated as a percentage on the oven-dry weight the percentage is known as the regain. If 100 parts by weight of material contain 20 parts by weight of water, the moisture content is 20% and the regain is 100 x 2o-r8o or 25%. Standard Regains.

Why is moisture regain important?

Moisture is reabsorbed by the textile, thus improving the quality and performance of the fabric. This regain also has a direct impact on the weight of the textile.

What is moisture regain of jute?

The moisture regain of jute fibers varies between 5% and 12% (Ali et al. 2016). The presence of large number of hydroxyl groups in the cellulose makes the jute fiber hydrophilic in nature and sensitive to regain moisture present in the atmosphere (Erdogan et al. 2016).
