What is the tensile strength of cotton in lbs per square inch?
If fiberglass is layed up in one direction only (unidirectional) its strength is greater than 100,000 psi for E glass and 250,000 psi for S glass. If layed up in cross plies like fiberglass cloth (G10) strength in tension is about 40,000 psi
How do you make translucent concrete?
To make translucent concrete, you'll need Fiber Optic Plastic (FOP) and ROCALITE microconcrete (www-rocalite.com) ROCALITE is a very strong mix of concrete in which all the components are micro-metric size and reacts with a very small amount of water, so the paste when wet has is like clay and when sets is stronger than normal concrete. This two factors allows to insert the fibers in the wet mix and keep them in place until the mix sets, about four days later. After that you'll need to polish the surface to let the fibers appears and allow the light passes from one end of the fiber to the other. The concrete keeps its appearance its strength, is characteristics but the light passes through it It is amazing

Which is better wet steam or dry steam?
If by dry steam you mean superheated steam then dry steam because it has a higher calorific value
When does your body conct current more readily?
When its wet
Why wet strength of cotton is higher than viscose fiber?
due to hydrogen bonding no of molecular rearrangement in the structure is more than viscoce in viscose hydrogen bonds break up is more in terms of molecular arrangement so wet strength of cotton is higher than viscose fibre rajarahul28@gmail.com
Is viscose strong?
Viscose has medium strength compared to other fibers like cotton or polyester. It is weaker when wet and can lose strength when exposed to moisture or sunlight over time. However, with proper care, viscose clothing can be durable and long-lasting.
How has paper changed over time?
well perhaps adhesives have been added basically you still grind up wet wood strain out the water and put it in a press cotton adds longer fibers for more strength Linen is a similar fiber to cotton... the seeds make tastier bred
Why is silk weaker when wet than dry?
Silk fibers have a unique structure that weakens when it absorbs water, causing the fibers to swell and lose their strength. The hydrogen bonds in the proteins of silk are disrupted by water molecules, leading to decreased tensile strength compared to when the fibers are dry.
What materials expand when wet?
Materials that expand when wet include natural fibers like cotton, wool, and rayon. When these materials absorb moisture, their individual fibers swell, causing the overall material to expand. This expansion can lead to changes in dimensions and may result in stretching or warping of the material.
Why it is easier to tear wet paper?
Wet paper fibers are weakened by water, making it easier for them to separate when pulled apart. Water molecules disrupt the hydrogen bonds that hold the fibers together, reducing the paper's overall strength and making it more prone to tearing.
Why does wet viscose has less strength than dry viscose?
viscose has 67 % amorphous region & 33% crystalline reason exactly reverse of cotton ,so viscose absorb more moisture than cotton as well as due to hydrogen bonding (formation of hydrogen bonds means addition of bonds) wet strength of cotton increases but in case of viscose no of hydyogen bonding breaks are much more(means break up of hydrogen bonds are much more than addition) so wet strength decreases.
What happens to wet cotton?
Eventually, the wet cotton will dry because of evaporation.
Does cotton shrink more than polyester?
Cotton fibers swell up when wet with water which in effect shortens the length of the fiber. The temperature of the water has no bearing. If the fiber is then dried quickly, the fiber permanently retains the swelled up and shortened attitude. If dried on low heat or no heat cotton will usually not shrink. This removes the water slowly and returns the fibers to their pre-wet size. Dry cleaning solvent evaporates quickly from cotton fibers allowing for a shrink free process. Most manufacturers preshrink cotton fabric prior to constructing garments. However, preshrunk garments may still shrink 2 to 3%. So if it is just right - get the next size.
What weather would stop cotton from growing?
Wet weather would stop cotton from growing because the cotton gets wet.
