Top Textile Interview Questions
1. What is Textile Engineering?
Textile Engineering (TE) or textile technology deals with the application of scientific and engineering principles to the design and control of all aspects of fiber, textile, and apparel processes, products, and machinery. These include natural and man-made materials, the interaction of materials with machines, safety and health, energy conservation, and waste and pollution control. Additionally, textile engineers are given training and experience in plant design and layout, machine and wet process design and improvement, and designing and creating textile products.
2. What is Fiber?
Fiber or fibre is a natural or man-made substance that is significantly longer than it is wide. Fibers are often used in the manufacture of other materials.
3. What is Yarn?
Yarn is a long continuous length of interlocked fibres, suitable for use in the production of textiles, sewing, crocheting, knitting, weaving, embroidery, or ropemaking.
4. What is Thread?
Thread is a type of yarn intended for sewing by hand or machine. Modern manufactured sewing threads may be finished with wax or other lubricants to withstand the stresses involved in sewing
5. What is Fabric?
A fabric is a material made through weaving, knitting, spreading, crocheting, or bonding that may be used in production of further goods (garments, etc.)
6. What is Nylon?
Nylon was the first commercially successful synthetic thermoplastic polymer.
It is a thermoplastic silky material that can be melt-processed into fibers, films, or shapes. It is made of repeating units linked by amide links similar to the peptide bonds in proteins.
Nylon polymers can be mixed with a wide variety of additives to achieve many different property variations.
Nylon polymers have found significant commercial applications in fabric and fibers (apparel, flooring and rubber reinforcement), in shapes (molded parts for cars, electrical equipment, etc.), and in films (mostly for food packaging).
7. What is Polyester?
Polyester is a category of polymers that contain the ester functional group in their main chain. Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are not. The material is used extensively in clothing.
Polyester fibers are sometimes spun together with natural fibers to produce a cloth with blended properties. Cotton-polyester blends can be strong, wrinkle- and tear-resistant, and reduce shrinking. Synthetic fibers using polyester have high water, wind and environmental resistance compared to plant-derived fibers. They are less fire-resistant and can melt when ignited.
Depending on the chemical structure, polyester can be a thermoplastic or thermoset.
Fabrics woven or knitted from polyester thread or yarn are used extensively in apparel and home furnishings, from shirts and pants to jackets and hats, bed sheets, blankets, upholstered furniture and computer mouse mats.
8. What is ASTM, ISO, ANSI Stands for?
ASTM: American Society for Testing and Materials.
ISO: International Organization for Standardization.
ANSI: American National Standards Institute.
