Sodium phosphate, usually listed as an ingredient on food labels, can be referring to either monosodium phosphate, disodium phosphate, or trisodium phosphate. It is usually an emulsifier (thickener) or a preserving agent. Disodium is the one most commonly used.
In chemical properties, there is very little difference. They are analagous to sodium chloride, table salt, and potassium chloride, sometimes used as a salt substitute. Sodium tripoly is by far the more common commercially, since it is less expensive to manufacture.

Does it possible use this materail(KTPP) instead of SODIUM TRIPOLYPHOSPHATE at textile process?

In my opinion there is no such difference. The ortho-prefix is added to be more precise (H3PO4 and linear polyphosphates) and to exclude the other possible meta-prefix (for cyclo-polyphosphates: (HPO3)n>2). Of this meta- no disodium-hydrogen salts - (Na2H)3+ - are known)

Monobasic refers to the presence of one electron donor (base), in this case the sodium (Na) so the chemical formula for monobasic sodium phosphate is NaH2PO4. Monohydrate refers to how hydrated, or the number of water molecules attached to this formulation of the monobasic sodium phosphate. Monohydrate means mono (one) water so the entire chemical formula is NaH2PO4 . H2O
Dibasic Sodium Phosphate has two basic atoms attached to it, in this case the sodium (Na), so the forumla is Na2HPO4. The absence of an indication of hydration state in this molecular formula tells us nothing of how many water molecules are associated with the formulation.
* Magnesium phosphate monobasic (Mg(H2PO4)2) -> 15 atoms * Magnesium phosphate dibasic (MgHPO4) -> 7 atoms * Magnesium phosphate tribasic (Mg3(PO4)2) -> 13 atoms
Sodium phosphate is a generic term for the salts of sodium hydroxide and phosphoric acid (soluble in water). They are:sodium dihydrogen phosphate, commonly termed monosodium phosphate, (NaH2PO4), is also known as "sodium phosphate, monobasic".disodium hydrogen phosphate, commonly termed disodium phosphate, (Na2HPO4) is also known as "sodium phosphate, dibasic".Trisodium phosphate, commonly shortened to just sodium phosphate, (Na3PO4), is also known as "sodium phosphate, tribasic".sodium aluminium phosphate, (Na8Al2(OH)2(PO4)4).
copper(II) phosphate can be made by mixing an aqueous copper(II) solution (i.e. CuCl2 or CuBr2) with an aqueous phosphate solution (i.e. monobasic or dibasic phosphate). A fluffy, light blue precipitate forms immediately upon addition of the copper(II) solution to the phosphate solution.

A monobasic acid releases on H+ when dissolved in water. Whereas a dibasic acid will release 2.
No. It is dibasic.

Yes

The first tells you there is 2 hydrogens and one potassium The second tells you there is 1 hydrogen and 2 potassiums
Dibasic potassium phosphate has the chemical formula is KH2PO4. The standardized solutions has a pH between 6 and 8.
Sodium Monohydrogen Phosphate heptahydrate, Sodium phosphate dibasic heptahydrate
No. Na2HPO4 is only a monobasic acid, corresponding to the remaining hydrogen atom. This is a very weak acid.
The number of replacable hydrogen in an acid is termed as its basicity. eg. HCl is monobasic, H2SO4 is dibasic

it is mono basic because it releases one hydrogen ion in solution.
