Natural cellulose fibres carry a small negative charge (zplateauZ11 mV) due to the presence of some carboxylic acid groups from oxidation at the primary hydroxylic
sites [3].
At a pH higher than 8, some of the hydroxyl groups on the hydroxymethyl side chains may also be ionized increasing the negative charge significantly [4].
The negative charges on the surface of cellulose repel anionic dyes and hence the
efficiency of dye fixation on cellulosic fibres is generally low. To counter this problem, a number of studies on cotton dyeing have been carried out to improve the dye uptake and fastness properties.
What else can I help you with?
Will an object that is negatively charged what will it attract?
Negatively charged objects
Which of the following particles is negatively charged?
An electron is negatively charged.
All compounds are negatively charged.?
No, all compounds are not negatively charged.
What can negatively charged objects?
Negatively charged objects can attract positively charged objects, repel other negatively charged objects, and cause static electricity buildup.
How are cathode charged?
negatively charged
Describe what happen when you rub a pieces of cloth on a balloon?
Rubbing a piece of cloth on a balloon creates static electricity. The friction between the cloth and the balloon transfers negatively charged electrons from the cloth to the balloon, causing the balloon to become negatively charged. This static charge can then attract or repel other objects, such as small pieces of paper or hair.
What is the overall electric charge if any on the balloon and on the cloth in Diagram A?
In Diagram A, the balloon and cloth are neutral overall. The balloon is positively charged (+Q) and the cloth is negatively charged (-Q), but the magnitudes of their charges cancel out, resulting in a net charge of zero.
When a balloon is rubbed against a cloth electrons move because?
When a balloon is rubbed against a cloth, electrons are transferred from the cloth to the balloon. This causes the balloon to become negatively charged and the cloth to become positively charged. The movement of electrons between the objects creates static electricity.
What will happen to the balloon and cloth in Diagram B if they are brought close together without touching?
they will repel
What happens if a balloon and a cloth after rubbing is in contact with a metal strip answers?
The balloon becomes negatively charged due to the transfer of electrons from the cloth. When the negatively charged balloon comes in contact with the metal strip, electrons will flow from the strip to the balloon, neutralizing the charge on the balloon. This process is known as static discharge.
Do balloons rubbed with wool cloth have the same charge?
No, balloons rubbed with wool cloth will have opposite charges. The balloon becomes negatively charged by gaining electrons from the wool cloth, while the wool cloth becomes positively charged by losing electrons to the balloon. This results in the balloons having different charges.
What kind of electric charge gets developed on the glass rod when it is rubbed with a piece of silk cloth?
When glass rod is rubbed with silk cloth it becomes positively charged and the silk cloth becomes negatively charged. This is because the glass rod looses electrons to the silk cloth which makes it positive and the silk cloth becomes negative.
What happens if plastic rod is rubbed with silk cloth?
When a plastic rod is rubbed with a silk cloth, electrons are transferred from the silk to the plastic rod. This results in the plastic rod becoming negatively charged and the silk cloth becoming positively charged. This effect is known as triboelectric charging.
Will rubbing a glass rod with a wool cloth create static electricity?
Yes, rubbing a glass rod with a wool cloth can create static electricity by transferring electrons between the two materials. This process causes the glass to become positively charged and the wool to become negatively charged, resulting in static electricity buildup.
What kind of electricity does the balloon have after it was rubbed on the woolen cloth?
The balloon will have static electricity after being rubbed on the woolen cloth. This results from the transfer of electrons between the balloon and the cloth, causing the balloon to become negatively charged.
Why does a balloon become negatively charged when rubbed with a wool cloth?
When a balloon is rubbed against a wool cloth, electrons are transferred from the wool to the balloon, leaving the balloon with an excess of electrons and a negative charge. This transfer of electrons is due to the difference in the materials' electron affinities, causing one material to lose electrons (becoming positively charged) and the other to gain electrons (becoming negatively charged).
Will an object that is negatively charged what will it attract?
Negatively charged objects
