Fabric direct from the loom is unattractive. To make the fabric attractive and acceptable to the consumer several finishing processes are applied. Sometimes special finishes are also applied to the fabric to make it serviceable for particular end use.

Garment engineering is a questioning technique, it questions each process/operation of the total work content and by using innovative methods of construction and technology you can reduce the work content and increase profitability.

As is the case with many industries, garment manufacturing requires multiple support operations to enable production in the facility. Many of these support operations are common to any manufacturing industry, such as administrative functions, facility and equipment maintenance, and boiler and backup power generator operation.

A useful filament was not produced until the last part of the 19th century when Swann and de Chardonnet extruded a solution of cellulose nitrate (collodion) through small holes (spinnerets). These pioneer manmade fibers were replaced by rayon fibers which were spun from an alkaline cellulose xanthate solution (viscose), which were in turn supplemented by cellulose acetate and many synthetic fibers.

In the simplest weaving arrangement, alternate warp yarns are over or under the shuttle as it moves in one direction and the warp yarn positions are reversed for the return stroke of the shuttle. This weave can be made on a loom with only two harnesses. In other arrangements, several warp yarns may be moved upward or downward together, or several filling picks may take place before the warp yarns change position.

Yarn making from staple fibers involves picking (opening, sorting, cleaning, blending), carding and combing (separating and aligning), drawing (re-blending), drafting (drawing into a long strand) and spinning (further drawing and twisting). Silk and synthetic filaments are produced by a less extensive procedure. Current high-production yarn-making operations are performed on integrated machines that perform this entire sequence as one combined operation.

Spun yarns, formed by twisting staple fibers together, are a cornerstone of textile manufacturing, valued for their versatility, texture, and strength. This article provides a comprehensive exploration of spun yarns, detailing their characteristics, production methods, types, and applications. By examining the spinning processes, fiber properties, and practical uses, the article equips textile professionals with insights to optimize yarn selection and production for diverse textile applications.
Article
Manmade fibers are manufactured using different mechanical and chemical processes for example Synthetic fibers from thermoplastics are produced by extruding the molten plastic through extrusion dies (spinnerets) into a stream of cold air that cools and solidifies the plastic. (The operation is referred to as melt spinning.)

Textile fibers, the fundamental building blocks of fabrics, must possess specific qualities to meet the demands of various applications, from apparel to technical textiles. This article explores the essential characteristics required for a fiber to be suitable for textile use, including strength, flexibility, length, fineness, absorbency, and durability. By examining these qualities, their measurement, and their impact on performance, the article provides a comprehensive guide for textile professionals to select and optimize fibers for diverse end-uses.

Blended yarns usually offer the best of several worlds i,e the breathability of wool or cotton, the durability of acrylic or nylon. Blends take dye differently and offer different color effects as well.Fiber blending has for a long time been practiced in textile processing. By mixing fibers of different types to form textile yarns, many advantages are achieved, such as property compensation or reinforcement between fibers, cost reduction without significant sacrifice of yarn performance.
