HTTEX ADC

(Acid buffer)

 

Brief information

-- HTtex ADC is a compound of polymeric organic acid with outstanding wetting, sequestering, dispersing and buffering, which is mainly used for pretreatment, mercerizing, alkali neutralization after dyeing.

 

Main composition

-- Polymeric organic acid.

 

General properties

-- Appearance:                            pale to yellow transparent liquid

-- pH:                                 2 – 3

-- Ionicity:                           anionic

-- Stability:                          stable to acid, alkali and electrolytes

 

Properties and fields of application

-- Outstanding buffer without any direct effect to alkali, but only reactivity. Does not damage the fibre, but retains the good hand fells and elasticity.

-- Outstanding wetting and dispersibility which can completely decompose and neutralize the alkali inside the fibres. It can reduce subsequent alkali wash times that saves water. Easily controls the pH of the fabrics. Avoids pH differences between water and inside-outside of the fabrics due to the strong reaction between other organic acids, inorganic acids and alkali that lock the alkali inside the fibres.

-- Avoids uneven dyeing as normal organic acid which achieves an outstanding leveling and better reproducibility.

-- Completely removes the white spots on the fabrics/yarns after reactive dye fixing with soda ash which helps a good leveling and bright shade.

-- When uses in cotton spandex elastic fabrics, prevents damage to the cotton fibres as excessive amount of other organic/inorganic acids, as well as prevents damage to the spandex fibres as alkalis, which help retain the fabric elasticity.

-- Reactive organic acid that has excellent neutralization to alkali without acid odour.

-- Outstanding sequestering to iron ions that avoids yellowing of fabrics during singeing or curing due to the iron ions.

 

Application

-- Padding:                          0.5 – 0.8 g/L, water retention: 75 – 85%

-- Mercerizing:                     1.5 – 4.0 g/L

-- Dipping:                          0.2 – 0.3 g/L

-- Note: HTtex ADC should avoid use with cationic surfactants in the same bath. HTtex ADC is an acid substance. Please rinse the eyes with plenty of water if splashed into eyes.

 

Packing and storage

-- Packing:                          125 kg/polyethylene drum

-- Storage:                           6 months in sealed container at room temperature.
