Q What is the anti creasing finishing process?
A The anti-creasing resin finishing of cotton fabric is through the active gene of the resin molecule and the hydroxyl of the cellulose molecule, forming molecular bridge or covalent bond under certain conditions, combing with the neighboring macromolecular chains in the fiber, reducing the relative slip motion.

Q What is anti creasing agent?
A Anticrease (conc) is a lubricating and crease preventing agent for natural and synthetic fibres and their blends. The product is recommended for all types of materials which are processed at low liquor ratio on machines with high shear forces in order to prevent the chaffing and crease marks.

Q What is scouring chemical?
A Scouring agent is used to remove naturally derived ipurities adhering to fibers and textiles, oil and paste that adhered to fibers in the spinning process, etc. It reduces troubles in the process of dyeing and finishing. Soaping agent is used to wash out residual dye, dyeing auxiliaries, oil etc.

Q What are soaping agents?
A What is "soaping agent"? Removal of excess unfixed dye present on the fiber surface is an important point to obtain a dyed product with excellent fastness. After dyeing, it is possible to remove unfixed dye by rinsing with a large amount of water.

Q What is the best temperature for soaping?
A 120-130 ° f.
for most soapers, the preferred temperature of soaping lye and oils are 120-130 ° f. In addition, many soapers and books believe it is helpful to have the lye and oil within 10 degrees of each other. The temperature range of 120-130 ° f is popular for several reasons.

Q What is the purpose of soaping?
A When used for cleaning, soap solubilizes particles and grime, which can then be separated from the article being cleaned. In hand washing, as a surfactant, when lathered with a little water, soap kills microorganisms by disorganizing their membrane lipid bilayer and denaturing their proteins.

Q What is the purpose of soaping the fabric after dyeing?
A The main purpose of soaping is exactly in order to remove the hydrolised dye that attaches on fiber, not set dyestuff and other impurity.

Q What are the different types of dispersing agent?
A Several well-known dispersants: polyvinyl pyrrolidone (pvp), sodium hexameta phosphate (shp), the sodium salt of edta (edta-na), sodium dodecyl sulfonate (sds), and sodium dodecyl benzene sulfonate (sdbs), were introduced to obtain a highly dispersed catalyst.
-
Q How do i choose a dispersing agent?
A The first question to answer when selecting your dispersing agent is whether you need electrostatic or steric repulsion. The answer is highly dependent on the system you formulate: is it solvent-based? Water-based? If your paint medium is apolar (solvent-based paints), the answer is simple.

Q What are the functions of dispersing agent in dyeing?
A In this dye bath, dispersing agent which disperses dyestuff evenly in the bath and leveling agent which enables to dye more than some hundred meter of fabric are added with water and disperse dye. Nicca combines these two chemicals in one agent for better workability.
