Log Book Science Fair Project: Take pictures during each step of the project. A science fair project is for learning more about science and you learn more if you enjoy your work. So in addition to the photographs that can be used on your display to show your scientific work, you might add some fun photographs to your journal.

A variety of fabrics were collected in respect to material cotton, polyester and fiber type smooth surfaces, fleece surfaces, knits and woven fabrics. Experiment group strips of fabric were treated with fabric softener.

Whereas the control group of the fabrics were washed without fabric softener.

Each fabric strip was suspended vertically from a constructed apparatus and lit for two seconds burning time before removing the flame. The fabric was allowed to burn for three more seconds. After the total allotted burning time 5 seconds in totalthe fire was extinguished, the fabric strip was removed from the apparatus and the amount of fabric that was burnt off was recorded.

Background Fire retardant fabrics are textiles that are naturally more resistant to fire than others through chemical threatment or manufactured fireproof fibers.

The term fire retardant as applied to organic i. The tests used specified in building codes, such as NFPAare more correctly flame resistance tests, which test a fabric's ability to resist ignition with the flame size and duration in the test conditions.

The result is a comparative test, which provides a measure of the material's resistance to propagating combustion caused by small scale ignition sources. These tests do not predict the burning characteristics of full scale hazards. In many cases, if exposed to a sufficiently large and sustained exposure fire, the fire retardant fabrics will burn vigorously.

Fabric flammability is an important textile issue, especially for stage drapery that will be used in a public space such as a school, theatre or special event venue. Federal regulations require that drapery fabrics used in such spaces be certified as flame or fire retardant.

Although all fabrics will burn, some are naturally more resistant to fire than others. Those that are more flammable can have their fire resistance drastically improved by treatment with fire retardant chemicals. The flammability of fabric can be drastically reduced through the use of fire retardants.

Some polyester fabrics are considered permanently fire retardant.

This is because fire retardant properties are built directly into the molecular structure of the fibers. Fabrics manufactured utilizing Trevira and Avora polyester fibers are considered inherently or permanently fire retardant.

Other synthetic fabrics may be considered durably fire retardant, fire retardant, or non-fire retardant. Durably fire retardant refers to a process in which polyesters are chemically treated during the manufacturing process with a non-water soluble chemical.

In other cases, synthetic fabrics may be topically treated with chemicals after the manufacturing process in the same manner as natural fibers such as cottonor may be untreated or untreatable and therefore considered non-fire retardant.

Aramid, like Twaron is used in modern fabrics to withstand high temperatures in industry and fire-fighting.

When a fabric is designated as inherently fire retardant, permanently fire retardant, or durably fire retardant, the flame retardancy will last for the life of the fabric. The drapery can be laundered or dry-cleaned as recommended by the drapery manufacturer.

In the case of fabrics that are designated as fire retardant, that have been topically treated with chemicals, the flame retardancy of the fabric will dissipate over time, particularly with repeated cleaning. These fabrics must be dry-cleaned with a non-liquid cleaning agent.Get ideas for 8th grade science fair projects.
