Explain weaving operations in fabric productions or types of weaving operations?

Basic Weaving Operation: Basic Loom Operations: Selvedges: Thread Count: Basic Weave Structures: Surface figured weaves: Basic Weaving Operation: The machine used for weaving fabrics is a loom. Before weaving yarns intended forwarp must pass through such operations as spooling, wraping and slashing to preparethem to withstand the strain of weaving process. These processes do not […]

Difference between warp and weft in fabric production

WARP: 1.Most Garments are cut in lengthwise 2.These are parallel to the selvedge 3.Yarns are finer in warp-wise direction as they have higher twist as warps have to go through lots of processing. 4.Filamentous yarns are preferred as warps 5.Yarns are stronger 6.Twist is more and yarns per inch is also more 7.Ply are preffered […]

What is polyester? Manufacturing process of polyester:

POLYESTER: Polyester is sometimes referred to as the “workhorse” fiber of the industry. The filament form of the fiber has been said to be the most versatile fiber and the staple form has been called the “big mixer” because it can be blended with so many other fibers, contributing its good properties to the blend […]

Explain nylon and its manufacturing process in man made fibers

NYLON Nylon was the first synthetic fiber. In 1928 the Dupont company decided to establish a fundamental research program. If anything was discovered it would be good for the company – a means of diversification. It was noticed that when a glass rod was taken out of one of the polyester stills the solution adhering […]

Meaning of acetate and triacetate? Manufacturing process of acetate and triacetate /difference between acetate triacetate?

ACETATE AND TRIACETATE: Acetate, which is properly called cellulose acetate (chemically di-acetate or secondary acetate) was first made by Paul Schutzenberger in 1869. The first use of this substancewas as a coating on cotton fabric or as a film similar to cellophane or plastic wrap. As a coating the substance was applied to fabric used […]

History of silk, growth and production, what are the process of silk?

History: The possibility of making cloth from the filament that the silkworm spins into a cocoon was first discovered in China about 2600 B.C. Legends tells us that a cocoon accidently dropped into a cup of tea that a Chinese Princess was having in her garden. The hot liquid softened and loosened the fiber, which […]

What is animal fibers? What are the animal fibers in textile designing?

ANIMAL FIBERS: High resistance. Good Good Burns readily Natural protein fibers are obtained from animal sources like hair and other secretion, fibers include covering from such animals as sheep, mohair goat, cashmere goat and camel. Secretions are obtained from the larva, or worm stage, of the silkworm, which spins the cocoon from which silk fibers […]

Definition of retting and what are the types or process of retting in flax and linen?

Retting: The bundles of plants are then steeped in water so that the tissue or woody bark surrounding the hairlike flax fiber will decompose, thus loosening the gum that binds the fiber to the stem. The decomposition is called retting. Retting only loosens the woody bark. If flax is not retted enough, the removal of […]

Process involved in Calendaring, Cire effect and moiré effect

It is a mechanical process that finishes the fabric, by passing it between sets of rollers and applying heat and pressure. The outside of the rollers can be smoother or engraved to give the perfect finish to the fabric, the structure of the rollers varies from hardened chromium plated steel to elastic thermoplastic rollers. By […]

What is Cotton Fiber Bleaching, Process of Bleaching, Bleaching Process chemicals

Bleaching Bleach is a chemical that removes colour or whitens a fabric via oxidation or reduction method. Many types of bleach have strong bactericidal properties, and are used for disinfecting and sterilizing. Bleaching is another important pretreatment next to scouring, performed on cotton fibres. This treatment is given to decolourize the natural colouring matter present […]
