GENERAL:

Vietan ZR is mainly used for the mild retannage of wet-blue stock. Its application is recommended before neutralization and/or as a fixing agent after the last acid fixation.

ADVISED APPLICATIONS:

It is advised to apply Vietan ZR during the retanning stages, before neutralization. Due to its strong cationic charge it can be used as a fixing agent for dyestuff and/or other anionic retanning agents or fatliquors. In waterproof articles it can be used as a capping agent resulting in high Maeser values, showing clear, bright and intense colours. Vietan ZR can be used in automotive upholstery with no negative effect on fogging values. Vietan ZR can be used for white and lightfast articles.

Vietan ZR may also be used in combination with Chromium Sulphate in the main tannage of wet blue leathers to reduce the amount of Chrome used and ensure total uptake of Chrome and virtually zero discharge of Chrome into the waste water. Add 2-4% Chrome powder at the usual stage after pickling run until fully penetrated 1-2 hours then add 2-4% Vietan ZR and continue usual process, slow basification with Vie Maxitan is highly recommended. Resultant Leathers are full, pass the usual shrinkage temperature and results in much whiter lighter shades.

Vietan ZR may also be sued for wet white tanning. Up to 14% may be used based on pickled pelt weight, addition may be done in one shot or in several shots of around 4% each time and running minimum of 60 minutes between each addition. Final pH should be adjusted to around 4 for optimum fixation.

For Wet white tanning without salt or acid suggest after deliming and bating wash well, new float 50-100% and first add sister product Vietan ZNT 3% run until penetrated, then add 3% Vietan ZR every 1-2 hours up to 9% total, check uptake and penetration and adjust pH to 4. Addition of fatliquors like Catfat or Vie Liquor GP may be added to prevent drying during storage and addition of Viecide Green 88 or Viecide Green Neo 0.3 to 0.5% is necessary to prevent fungus

For retanning:

  • Initial wash

  • Drain

  • Retanning with 2.0 % up to 5.0 % Vietan ZR, run for 60 minutes

  • Neutralize & wash

  • Continue as usual

  • As fixing agent:

  • Final acid fixation

  • Add 0.5 % up to 1.5 % Vietan ZR, run for 30 minutes

  • Drain/wash

As a Synergistic Tanning agent with Chromium Sulphate:

  • Pickle etc as usual

  • Add 2 % up to 3 % Vietan ZR, run for 10 minutes add the Chrome powder 4 % is all that is needed to achieve usual shrinkage temperature

  • Drain/wash

  • Alternatively add Chrome powder first run 30 minutes then add 2% to 3% Vietan ZR continue as usual

  • Up to 99% Chrome is exhausted reducing pollution and wastage of Chrome

As a Wet White Tanning agent:

Vietan AL Application

Vietan AL may be added as a powder or diluted with water then added to the process vessel in the normal way. As Vietan AL is strongly cationic it will precipitate anionic dyes, therefore the product must be always be applied in a fresh bath. It can be applied as either an aftertreatment, to improve fastness properties or as an intermediate to help build up dye shade. When used as an intermediate treatment, the second portion of dye can be added into the same bath.

On upper leathers it can be applied prior to retanning, giving an intensive surface shade with low offers of dye, however penetration will be reduced.

Vietan AL can also be used in chrome tanning, to produce a fuller leather with a pleasant handle and improved dye yield.

It can also be applied as a capping agent for waterproof leathers.

Vietan AL is suitable for tanning all types of fur skins in a bath or by the brushing process. Viebeam Delimer AGS in conjunction with formic acid has proven to be the best option for pickling with regards to handle, lightness and stretchiness of the resultant skins. Tannage with Vietan AL is subsequently carried out in a fresh bath. Incorporation of Viesyn KN enhances the fixation of the aluminium complex to the skin fibres and promotes production of a still softer fur skin leather. For even better results addition of Vietan AP with or after the Vietan AL gives the most overall synergistic results increasing the shrinkage temperature to over 80oC and increasing fullness and softness without the need to basify. 3% Vietan AP is recommended.

When added to a chrome tanning bath it reacts with the acid present, giving a steady, controlled rise in pH. There are no pH peaks to cause un-desirable precipitation of the chrome. The rate of rise in pH is dependant upon temperature, float level and mechanical action. The final pH of the tanning bath can be controlled by the amount offered.

The main characteristics are:

  • Carefully controlled particle size distribution

  • Gradual pH rise

  • Safe and consistent results

  • Uniform chrome distribution in the final wet blue

  • High shrinkage temperature

Properties:

  • Appearance: Off white powder

  • Active substance: circa 84 %

  • pH of 10% solution : 9.5 +- 0.5

  • Shelf life: Minimum 1 year under cool and dry conditions when stored in original, sealed packaging

Vie Maxitan Application

For basification of chrome tanned leathers Vie MaxiTan is best added without dilution as soon as full penetration of the chrome has been achieved. The total amount offered will depend on the pH of the pickle system and the % of chrome powder used, normally an addition of 0.45 – 0.6 % Vie MaxiTan is recommended. As it dissolves slowly, Vie MaxiTan requires a continuous running time of at least 8 hours (depending upon drum speed and bath temperature) to achieve its full effect.

Dye Concentration Viefix T offer:

  1. Produces a gradual increase in pH leading to a perfect chrome distribution throughout the substance of the Leather

  2. The fine particle size eliminates the risk of abrasion to the pelt and ensures consistent results

  3. Vie MaxiTan reacts with acids to give only soluble salts. Alkalis based on calcium lead to residual levels of insoluble calcium sulphate in the pelt, which can have a detrimental effect on the dyeing of leather and often results in white stains and patchiness on the final crust.

  4. Saves time and labour because the need for repeated small additions of alkali is eliminated, reduces human error.

Example Applications:

% based on pelt weight

Full substance buffalo and cow hides: 0.4 – 0.6 %

Lime split buffalo and cow hides: 0.4 – 0.6 %

Sheep & goat skins: up to 0.6 %

Viebeam CO – Bleaching agent

APPLICATION: BLEACHING/PICKLING

Viebeam CO is used as a bleaching agent on hides, skins or pelts. When used in the pickle, it bleaches any remaining hair root pigments giving a clean pelt. It is particularly recommended for use in the production of full aniline, white bleached and pastel coloured leathers.

The main characteristics are:
  • Strong Bleaching Action

  • Promotes Cleaner Pelts

  • Improves Dye Levelness And Brilliance

  • Minimal Effect Upon Leather Strength And Structure

PROPERTIES:
  • Appearance: pale greenish yellow liquid

  • Chemical character: chlorine containing oxidising agent

  • Active substance: approx. 30 %

  • pH value: 13.0 – 14.0

  • Storage stability: min. 1 year under cool, dry conditions when stored in original, sealed packaging. At temperatures below +5 °C some crystallization and deposition on the container bottom may occur.

  • Reaction: Viebeam CO has a strongly alkaline reaction and must not be directly mixed with acids, reducing agents or highly flammable substances acids – chlorine dioxide gas is released with the risk of explosion reducing agents – risk of rapid, exothermic decomposition highly flammable substances – risk of fire and explosion

APPLICATION:

Viebeam CO should be diluted with water before addition of the process vessel. As with all oxidising agents, certain precautions must be observed with Viebeam CO. In an acid medium, Viebeam CO releases chlorine dioxide gas, the active oxidising agent. For this reason, the undiluted product should not be brought into contact with concentrated acids or reducing substances. This can result in spontaneous evolution of gas, sometimes accompanied by ignition. Viebeam CO should therefore be mixed only in diluted form with diluted acids. Spills or splashes of Viebeam CO must be rinsed away with water immediately. Empty containers should be rinsed with water immediately after use. The primary field of application for Viebeam CO is pickle bleaching of heavily pigmented hides and skins. The product is added to the salt bath and run for 15 – 30 mins before addition of acids. Pickling is carried out in the usual way but care must be taken not to open the drum during the process. At the end of pickle bleaching, any excess chlorine dioxide remaining must be neutralised with a reducing agent such as sodium thiosulphate or sodium bisulphite. Potassium iodide-starch paper is used to test for complete removal of the excess oxidising agent. Reptile skins can also be bleached with Viebeam CO . Unlike permanganate bleaching, Viebeam CO bleaching does not impair tensile strength. Viebeam CO can be used to lighten or completely bleach faulty dyeings. In this case, the degree of bleaching will depend on the structure of the dyes to be bleached.

Sample applications:
  • Pickle bleaching of hides: up to 1 %, based on pelt weight

  • Pickle bleaching of lizard and reptile skins: up to 10 %, based on pelt weight

  • Bleaching of vegetable tanned reptile skins: up to 150 %, based on dry weight of skins

Viebeam RS can be diluted with cold water and added to the vessel in the normal way. Suitable for use on all hide or skin types. The reduced swelling effect helps to give a smooth, fine grain on the leathers. The product does possess an unhairing effect, the reduction in swelling also enhances the effect of sulphides if they are used, giving a more effective removal of hair root / scud from the grain. The advantage of their use is that they considerably reduce the amount of sulphide consumed and discharged with the wastewater. On the other hand, these chemicals are much more expensive than sulphides. Owing to their high price, these products are mostly used in instances where effects other than environmental improvement are sought . For example, liming with these compounds yields a lower degree of swelling than using lime and sulphide only. This may be expected to have a positive effect on the area yield and the smoothness of the grain.

GENERAL: Vietan ZNT is mainly used for the mild retannage or neutralization of wet-blue stock. Its application is recommended for neutralization and/or as a retanning agent along with other syntans, polymers etc.

ADVISED APPLICATIONS: It is advised to apply Vietan ZNT during the neutralizing stage, or any time during retanning. Vietan ZNT can be used in automotive upholstery with no negative effect on fogging values. Vietan ZNT can be used for white and lightfast articles.

RECOMMENDATIONS: For Neutralization use 2-4% Vietan ZNT alone or with other masking salts like Sodium Formate run for required time. Advantage is if used alone washing may not be necessary and a compact retanning system may be done in the same bath saving much water in the process

Vietan ZNT may also be used in combination with Chromium Sulphate in the main tannage of wet blue leathers to reduce the amount of Chrome used and ensure total uptake of Chrome and virtually zero discharge of Chrome into the waste water. Add 2-4% Chrome powder at the usual stage after pickling run until fully penetrated 1-2 hours then add 0.5-1% Vietan ZNT and continue usual process, slow basification with Vie Maxitan is possible but may not be necessary recommended. Resultant Leathers are full, pass the usual shrinkage temperature and results in much whiter lighter shades.

Vietan ZNT may also be used for wet white tanning without salt or acid suggest after deliming and bating wash well, new float 50-100% and then add 3-4% Vietan ZNT run until penetrated, then add 3% Vietan ZR every 1-2 hours up to 9% total, check uptake and penetration and adjust pH to 4. Addition of fatliquors like Catfat or Vie Liquor GP may be added to prevent drying during storage and addition of Viecide Green 88 or Viecide Green Neo 0.3 to 0.5% is necessary to prevent fungus

For retanning compact system:
  • Initial wet back/wash/drain

  • Retanning with 2.0 % up to 5.0 % Vietan ZR, run for 60 minutes

  • Neutralize with 2-4% Vietan ZNT check cut and pH

  • Continue retanning as usual

As a Synergistic Tanning agent with Chromium Sulphate: Pickle etc as usual

Add 4-5% Chrome powder run until penetrated add 0.5-1% Vietan ZNT run to completion check final ph 4. Much less chrome is needed to achieve usual shrinkage temperature of over 100oC

  • Up to 99% Chrome is exhausted reducing pollution and wastage of Chrome

  • As a Wet White Tanning agent

  • After Deliming/Bating, drain and wash well, new float 50-100% add 3-4% Vietan ZNT run 1-2 hours until penetrated, add 2-4% Vietan ZR every 2 hours until tannage is complete, check shrinkage 75oC

VIEGETAL BI APPLICATION:


Vietan BI should be diluted with warm water and added to the drum in the normal way. Vietan BI is recommended for use on splits destined for finishing processes. The fibre structure is filled by the impregnating polymer and provides a smooth surface after buffing. This obviates the need for application of a buffing ground followed by rebuffing and dust extraction thus simplifying the finishing operations. It is usually applied either at the end of the process before final acidification or in conjunction with the final fatliquor. It can also be used to achieve a very fine, nubuck like suede on splits.
