Tlp Neutral Is M.l. Latest Development In The Area Of Enzymes For Finishing Of Cellulosic Materials Like Cottons, Viscose, Tencel Etc And Is Widely Used For Giving Stone Washed Effect On Denims. 

Tlp Neutral Is A Neutral Cellulolytic Enzyme. Enzymes Are Obtained On Fermentation Of Genetically Engineered, Non – Pathogenic Moulds. Tlp Neutral Imparts Greyish Cast To The Indigo After Enzyme Washing.

Advantages Of Using Enzymes:

1.Unlike stones, enzymes are specific in action and hence create a very consistent, homogeneous effect.

2.Enzymes are produced by controlled fermentation and hence batch wise quality can be maintained.

3.Fabric damage losses are almost nil.

4.Machine damage does not occur.

5.Enzymes are user friendly and the process is less laborious.

6.Washing discharges are completely biodegradable and hence eco-friendly.

Enzymatic “stone Washing Or Bio Washing” As It Is Referred To Comprises Of 3 Main Steps:

De sizing

Biowashing

Finishing

De sizing :

This Is The First Step In Bio washing And Involves The Removal Of The Starch Size From The Denim Fabric / Garment Using A Starch – Hydrolyzing Enzyme System Such As Del De sizing. De sizing Is Recommended To Be Carried Out At An Optimal Ph Range Of 6.5 - 7.0 And An Optimal Temperature Range Of 65 - 70 Deg C (150 – 160 Deg F) For A Period Of 20 Mins With A Del De sizing Dose Rate Of 4 To 6 Grams Per Kg. Of Denim Fabric / Garment ( 1.4 Oz Per 100 Lbs Of Denim Fabric).

However, The Effective Range Of Temperature And Ph As Well As The Enzyme Dose Level Is Wider Than The Above Optimal Range And May Be Adjusted Based On Individual Requirements. M.l.’s Technical Services Will Be Only Too Pleased To Provide Any Assistance On De sizing.

Tips To Reduce Creases :

1.Denim Trousers etc., can be steam blown before desizing.

2.Pre wetting and soaking can be done with suitable wetting agents.

3.Trousers can be turned inside out while desizing.

4.Lubricators can be used while pre- wetting.

5.Enough water level during Desizing operation has to be ensured.

Biowashing :

On Completion Of De sizing Which Is Traditionally Checked By “ Hand feel” To Observe Absence Of “stickiness”, The Liquor Is Drained And Rinsed With Plain Water. The Fabric / Garment Is Then Steeped In Water At A Ratio Of Approximately 1:5 To 1:10 And The Temperature Is Raised To 55 Deg C. The Starting Ph Of Water Should Be At 6.0 .

Tlp Neutral Is Then Dosed At 5-10 Gms Per Garment. Bio Washing Is Carried Out For A Period Of 60 To 90 Mins Depending On The Tint And Enzyme Effect Desired Ensuring That The Temperature Is Maintained Between 50 - 55 Deg C
