Classification of Textile Fibre

Textile Fibers is the basic and principle raw materials to produce various types of textile finished products. A fiber that can be spun into yarn or processed into textile such as a woven fabric, knit fabric, lace, felt, non-woven etc by means of an appropriate interlacing method is called as Textile Fibers.

Generally Textile Fibers can be classified into main two types:

👉 Natural fiber And,

👉 Synthetic fiber/Manmade fiber/Artificial fiber.

Textile Fibers can also be classified in the following ways:

✍ Classification of textile fibers based on sources

✍ Classification of textile fibres based on polymer

Textile Fibers and Forensic Science

Textile fibers are a key form of trace evidence, and the ability to reliably associate or discriminate them is crucial for forensic scientists. While microscopic and instrumental analysis can be used to determine the composition of the fiber.

Additional specificity is gained by examining fiber color.

Hello There,

I again want to share This video with those who want to ask if this field is good for them or not.

My team is getting approx 100 queries related to this only (We try to satisfy everyone with our answers but we heartly apologise if we couldn't).

I want to say that no field is good or bad, the choice, interest and time make it work.

Don't go for higher job opportunities, see if you can grab the only available job with your potential.

Is that field or subject suits your personality?

At This time when everyone is struggling with job crisis then no field is going to provide you one without dedication and knowledge and as you know forensic do not seek for knowledge only it also seek for reasoning, logic, sharpness.

So know yourself first so no one can reject you.

Don't forget to like and comment your opinion on this.. We want to make sure that everyone understand the good and bad..

Watch This video to know more...

Footprint Analysis:-

Evaluation of two-dimensional footprint impressions for comparison purposes are carried out in the field of forensic identification by one or more of the following methods; overlay, Robbins, Gunn, Rossi and the Optical Centre Method.

Three methods for barefoot examination are commonly employed–

A.) Gunn Method: One such method devised by Gunn involves taking multiple linear measurements of the footprints that are being compared. Gunn's basic method involves drawing six lines, five of which come from the rear foot and extend to the apex of each digit. A sixth line is then drawn across the ball of the foot at the widest area.

B.) Optical Centre Method: A distinct point on the foot is identified and concentric circles are drawn in its most suitable location. This point is then isolated and then connected to other recognized regions of the footprint by means of lines.

C.) Overlay Method In the overlay method, the forensic practitioner places a sheet of clear acetate over the question print. The question print may be recovered from the crime scene and presented either in its true form (for example a bloody footprint on a piece of flooring, removed in its entirety), or as a latent print (for example on lifting film) but more often than not, as a life-sized evidence photograph. A fine-tipped marker pen is used to trace around the outline of the exemplar print and the acetate then transferred and placed over the question print.

Question- What is Computer Forensics? Answer- Computer forensics applies forensics procedures to digital evidence. This process involves systematically accumulating and analyzing digital information for use as evidence in civil, criminal, or administrative cases. Computer forensics differs from network forensics, data recovery, and disaster recovery in scope, technique, and objective.

Question- What should you know to become a successful Computer Forensic Investigator? Answer- To be a successful computer forensics investigator, you must be familiar with more than one computing platform. To supplement your knowledge, develop and maintain contact with computer, network, and investigative professionals.

Question- What is Different Between Private Computer Investigation and Public Computer Investigation?

Answer- Public and private computer investigations differ, in that public investigations typically require a search warrant before seizing digital evidence. During public investigations, you search for evidence to support criminal allegations While During private investigations, you search for evidence to support allegations of abuse of assets and, in some cases, criminal complaints.

Question- What is Forensic Graphology? Answer- Forensic graphology is the study of handwriting. It is also known as graphoanalysis. Graphology is a process that is used by some to attempt to determine personality traits and details about a person based off of their handwriting. Forensic investigators use handwriting pattern/technology to determine personality traits of an individual.

Question- What is Crime Scene Sketch?

Answer- A crime scene sketch is a permanent record of the size and distance relationship of the crime scene and the physical evidence within it. The sketch serves to clarify the special information present within the photo-graphs and video documentation, because the other methods do not allow the viewer to easily gauge distances and dimensions. A sketch is the most simplistic manner in which to present crime scene layout and measurements. Photographer /camera positions may be noted within a sketch also.

Question- Why is a sketch important to crime scene documentation?

Answer- ■ It accurately portrays the physical facts.

■ It relates to the sequence of events at the scene.

■ It establishes the precise location and relationship of objects and evidence at the scene.

■ It helps to create a mental picture of the scene for those not present.

■ It is a permanent record of the scene.

■ It usually is admissible in court.

■ It assists in interviewing and interrogating.

■ It assists in preparing the written investigative report.

■ It assists in presenting the case in court. Well-prepared sketches and drawings help judges, juries, witnesses, and others to visualize the crime scene.

Question-When should sketches be made?

Answer- Sketch all serious crimes and accident scenes after photographs have been taken and before anything is moved.

Sketch the entire scene, the objects, and the evidence.

Question- How many types of sketches are made of crime scene?

Answer- Two types of sketches are made with regards to crime scene documentation: 1.) Rough sketches, and 2.) Final/finished sketches.
