For all other textile processing 3rd sem syllabus for diploma m scheme tndte you can visit Textile Processing 3rd Sem Syllabus for Diploma M Scheme TNDTE Subjects. The detail syllabus for fibre and chemical analysis practical is as follows.
Rationale:
Chemicals used in the processing laboratory should be pure and should have 100% strength. Therefore it is essential to acquire practical knowledge in analyzing the water and chemicals for their purity. In addition, fibre analysis is also an important skill to learn.
Guidelines:
- All the twelve experiments given in the list of experiments should be completed and given for the board practical examination.
- In order to gain in – depth practical knowledge, every student should individually carry out the experiments in the laboratory.
- The external examiners are requested to ensure that a single experimental question should not be given to more than three students while examining a batch of 30 students during Board Examinations.
Allocation of Marks:

Complete List Of Experiments In Details
- Analysis Of Fibres In Blends
- To analyse the fibres in blends such as Polyester/Cotton and Polyester/Wool and Acrylic/wool.
- Estimation Of Hardness, Ph And Efficiency
- To estimate the hardness and pH of water. It imparts the knowledge of estimating the hardness and pH of water.
- Estimation Of Purity
- To estimate the purity of sulphuric acid, hydrochloric acid, caustic soda, sodium carbonate, and sodium hydro sulphite.
- Volumetric Analysis
- To do the volumetric analyze of H2O2 (iodimetry) solution.
- Measurement Of Specific Gravity
- To measure the specific gravity of given solution by using hydro meter.
- Test For Determining Ionic Nature
- To do the test for determination of ionic nature of given substance.
In this test there are two different compositions of fibres from which the individual compositions of fibres can be analysed. Such as Polyester/Cotton and Polyester/ Wool and Acrylic/wool.
This gives the knowledge of estimating the purity of sodium carbonate, caustic soda, sulphuric acid, hydrochloric acid and sodium hydro sulphite.
It gives the knowledge of analyzing the strength of H2O2.
In this experiment the specific gravity of given solution can be measured by using hydro meters.
In this test ionic nature of given substance can be determined.
Specific Questions For The Practical Class Work
- Analysis for individual composition of fibres in blends – Polyester / Cotton fabric.
- Analysis for individual composition of fibres in blends – Polyester / Wool fabric

Safety Precations To Be Followed
- Wearing the gloves in hand while taking and mixing the dyes stuffs and chemicals
- Should wear safe foot wear, preferably shoes.
- Should keep their shirts tucked in.
- Should inform the staff in charge immediately if they find any unsafe condition in the machine.
- Should not wear loose shirts.
- Should not open the doors and covers while the machine is running.
- Should not start running a machines without doing regular safety checks and closing the safety doors.
- Exhaust fans should be provided in the laboratory, so that unwanted smell and toxic air can be forced out
