Textile Job Interview Questions and Answers in the Textile Industry:
These are the Top Textile Interview Questions and Answers for Textile Engineers, you can consider them as exclusive interviews of the textiles industry:
1. What do you mean by After treatment?
Any treatment done after fabric production is termed as after-treatment. In the case of dyeing, it refers to treating dyed material in ways to improve characteristics; in non-woven, it refers to finishing processes carried out after a web has been formed and bonded. Examples are embossing, creeping, softening, printing, and dyeing.
2. What do you mean by Air Brushing?
Blowing color on the fabric or paper with a mechanized pneumatic brush is known as airbrushing.

It is a chemical process for sealing short, fuzzy fibers into a yarn. Fabrics made from air-conditioned yarns are porous. These fabrics are also cooler because they allow more air circulation.
4. What do you mean by Air Jet Spinning?
It is a spinning system where yarn is made by wrapping fibers around a core stream of fibers with compressed air. In case of this case, the fibers are drafted to a perfect sliver size and then fed to the air jet chambers, where they are twisted, at first in one direction, then in the reverse direction in a second chamber.

Fibers of animal origin, such as wool, alpaca, camel hair, and silk, are termed animal fibers.
7. What do you mean by Antifoaming Agents?
It is an additive that reduces the formation of bubbles within or on the surface of a liquid by reducing the forces that support the bubble’s structure.
8. What do you mean by Bar Tack?
Bar Tack is re-stitching over a very short length to increase the area and provide a high load-bearing strength. For example, the bent loop and the corners of the pocket are bar tacked.
9. What do you mean by Back Stitch?
A kind of hand stitch for sewing apparel, which could also be done by machine.
10. What do you mean by Beaming?
In the textile sector, the primary operation of warp knitting, in which ends withdrawn from a warping creel, evenly spaced in a sheet, are wound into a beam of substation length, is termed beaming.
11. What do you mean by ” beating up “?
It is the third of the three primary motions involved in weaving. It consists of forcing the pick of weft yarn left in the warp shed up to fill the cloth.
12. What do you mean by Bobbin?
It is a cylindrical or slightly tapered barrel with or without flanges on which yarn is wound.
13. What do you mean by Backing Warp (Or weft)?
Additional warp or weft on the back of the fabric, bound or stitched to the ground structure, so that it does not interfere with the appearance of the face, giving greater weight, thickness, warmth, etc.
14. What do you mean by Basic Dyes?
It is a class of positive icon-carrying dyes known for their brilliant hues. These types of dyes are composed of large molecules, water-soluble salts that have a direct affinity for wool and silk, and can be applied to cotton with a mordant.
15. What do you mean by Basket Stitch?
In the case of this knit construction, purl and plain loops are combined with a preponderance of purl loops in the pattern courses to give a basket weave effect.
16. What do you mean by Batch?
A batch is normally a group of unit products of the same structure, type, color, and finish, composition, and class manufactured at essentially the same time and submitted at any one time for inspection and testing.
17. What do you mean by Blended Yarn?
It is a thread in which the different component fibers are thoroughly mixed.
18. What do you mean by BOD?
BOD means Biochemical Oxygen Demand. It is a method of measuring the rate of oxygen due to biological oxidation, i.e., the required oxygen to oxidize the organic matter in sewage by bacteria.
19. What do you mean by Bonded Fabric?
Bonded fabric is a layered fabric structure wherein a face or shell fabric is joined to a backing fabric with an adhesive that does not significantly add to the thickness of the combined fabrics.
20. What do you mean by C.B Line?
It is a straight line, bottom up, vertically along the midpoint of the back part of the shirt.
21. What do you mean by Cheeses?
It is a cylindrical-shaped package of thread in which threads are cross-wound, and that package has no flanges.
22. What do you mean by Crocking?
It is the act of taking out color from the dry or wet cloth by rubbing or scouring.
23. What do you mean by combined yarn?
A yarn prepared from a sliver that is first carded and later combed in order to produce a more regular and smoother final product.
24. What do you mean by Carded Yarn?
Carded Yarn is a type of yarn which produced from fibers that have been carded but not combed.
25. What do you mean by Creeling?
The mounting of supply packages in a creel to feed fiber to a process, beaming or warping
26. What is PPM?
The number of grains of calcium carbonate which is present in one million grains of water is termed PPM
27. What is water softening in the Textile Wet Process?
To remove the impurities of hard water by some desirable process is known as water softening.
28. What is a detergent?
The compound that gets oriented at the interface between water and air and reduces interfacial tension or surface is known as a detergent. There are mainly two types: ionic and non-ionic.
29. What is an enzyme?
It is one type of biocatalyst. It is based on protein. It is soluble in water but insoluble in acid and alkali.
30. What is viscosity in a water solution?
It is the ratio of shear stress to the rate of shearing.
31. What is steaming?
This consists of submitting printed fabrics to the action of steam for varying periods at various pressures.
32. What is blotch print?
Prints where both the background and motif color are printed into the fabric using a direct printing process.
33. What is a brand?
A trade name identifying a manufacturer or product.
34. What is color forecasting in a Dyeing Mill?
The selection of ranges of colors that are deemed to be those that will be wanted for a particular product or market at a particular time in the future.
35. What is Acrylic fiber? How is it made?
Acrylic fiber is made from a polymer called polyacrylonitrile (PAN). The manufacturing process involves several steps, including polymerization, wet spinning, drawing, and heat-setting.
36. What is Colour Fastness in the Textile Industry?
The term colour fastness can be described as the ability of colouring matters on the fibre to withstand the physical and chemical actions during the processes of manufacture and in daily use of the dyed material.
37. What is Grey Scale in Color Fastness testing in the Textile Industry?
The visual assessment of colour change caused by a particular agency (apart from light fading) is assessed as the colour contrast between the original and tested sample using a grey scale. Grey scale is a 5 pairs of grey colour chips showing visual differences in colour. The grades are coded from 1 to 5, poor, moderate, good, very good, and excellent, respectively.
38. What is pH? What has a pH of 7?
In practice, the pH of any liquid can be measured directly by using a pH meter. A figure expressing the acidity or alkalinity of an answer on a logarithmic scale on which 7 is neutral, lower values are more acidic, and higher values are more alkaline. But it is a big question what pH means. What is the meaning of 5 or 10? Actually, pH is the relative amount of H+ in a solution. It is defined as the negative logarithm of H+ in a solution. It measures the moles of H+ solution.
39. What is Nylon Fiber?
Nylon fiber is a synthetic polymer made of long chains of polyamides. It has become one of the most widely used synthetic fibers in the world. Nylon is known for its strength, durability, and versatility, and is used in a wide range of products, from clothing and carpets to car parts and toothbrush bristles.
