Study Notes

Yarn

Yarn is a continuous strand made from natural or synthetic fibers, essential in weaving and knitting for cloth production.
Defined as a product of significant length and small cross-section, consisting of fibers and/or filaments, with or without twist.

Fabric

Fabric is a textile product formed by combining yarns and/or fibers, providing strength, flexibility and cover for garments.
Produced by woven or knitted methods; non-woven fabrics can be made exclusively from fibers.

Fabric Classification

Woven Fabrics: Created by interlacing two sets of yarn. Require sizing and extensive yarn preparation. Account for approximately 48% of textile production.
Knitted Fabrics: Made by looping yarns together. Do not need sizing and have higher production capacity (about 52% of textile production). More elastic than woven fabrics.
Non-Woven Fabrics: Lack structured internal form, produced by bonding methods. Mostly used for hats and interlining.
Miscellaneous Fabrics: Created from loop stitching through backing fabric, do not require traditional weaving processes.

Comparison between Woven and Knitted Fabrics

Woven fabrics have lower elasticity and require intensive preparation compared to knitted fabrics.
Woven fabrics cost more and have higher dimensional stability, while knitted fabrics offer greater elasticity and production efficiency.

Characteristics of Woven Fabrics

Limited stretching both lengthwise and widthwise.
Known for excellent covering power, ease of processing, long lifespan, and suitability for dyeing and printing.

Weaving Machines

Weaving occurs on looms, which vary based on weft insertion methods.

Uses of Woven Fabrics

Commonly used in apparel, bed linens, upholstery, curtains, towels, carpets, filter cloths, tent materials, and specialty items like astronaut suits.

Types of Woven Fabrics

Includes dress fabrics, denim, terry toweling, velvets, corduroys, jacquard and brocade fabrics.

Woven Fabrics Specifications

Characteristics measured include ends per inch, picks per inch, warp/weft counts, crimp percentage, fabric weight per area, and weave design.

Flow Process of Weaving

Weaving preparation involves warp and weft preparation processes, with warp preparation being more intensive due to its complexity.

Summary of Weaving Preparation

Both yarn types undergo extensive preparation prior to being loaded onto the loom, essential for productive weaving.
