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.

Which of the following particles is negatively charged?
An electron is negatively charged.
Will an object that is negatively charged what will it attract?
Negatively charged objects
All compounds are negatively charged.?
No, all compounds are not negatively charged.
Does every atom have a negatively charged nucleus surrounded by negatively charged electrons?
No. Every atom has a positively charged nucleus surrounded by negatively charged electrons.Unless you are talking about antimatter. The atoms of antimatter have negatively charged nuclei and surrounded by positively charged positrons
How are cathode charged?
negatively charged
Can a negative charged object attract other negative charged objects?
objects can be negatively charged when it is rubbed with another object; a woolen cloth for example. this is because the electrons from the woolen cloth will be transferred to the object which is being rubbed! only electrons can be transferred to the object and make the object becomes negatively charged.
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 when a charged ebonite rod is brought close to water?
Ebonite rod becomes positively charged and the fur becomes negatively charged. Hold on electrons: Fur > Ebonite rod So, the ebonite rod loses its electrons to the fur and the fur becomes negatively charged.
Is lighting negatively charged or positively charged?
Negatively charge
Which of the following particles is negatively charged?
An electron is negatively charged.
Will an object that is negatively charged what will it attract?
Negatively charged objects
Are electron negatively charged atoms?
No. An electron is negatively charged but it is not an atom. It is a subatomic particle and the negatively charged component of an atom.
When a polythene rod is rubbed with a duster it becomes negatively charged . why?
Because electrons are rubbed off the cloth and build up on the polythene.
A negatively charged particle?
A negatively charged atom is called an electron.
What's negatively charged particle?
A negatively charged partical is an electron.
All compounds are negatively charged.?
No, all compounds are not negatively charged.
Does every atom have a negatively charged nucleus surrounded by negatively charged electrons?
No. Every atom has a positively charged nucleus surrounded by negatively charged electrons.Unless you are talking about antimatter. The atoms of antimatter have negatively charged nuclei and surrounded by positively charged positrons
