What kind of fabric is the most comfortable, which lining is the most suitable, and how do you choose the right materials for your garments? If you want to master these questions, you should first familiarize yourself with the most basic knowledge of garment materials. Below, we’ve compiled ten key points for everyone to learn together^^

　　1. The concept of apparel materials—apparel materials refer collectively to the various fabrics, trims, and packaging materials used in the manufacture, decoration, and packaging of garments.

　　2. Scope of Apparel Materials — Apparel materials are categorized into the following three areas: (1) Outer fabrics: cotton, linen, wool, silk, synthetic fibers, and various blended fabrics. (2) Apparel trims: linings, padding, interlinings, pocketing fabrics, sewing threads, buttons, and decorative materials. (3) Packaging materials: wood, wrapping paper, paper boxes, cardboard boxes, desiccants, mothproofing agents, and mold‑preventive agents.

　　3. Essential Properties of Apparel Materials — Apparel materials must possess three key characteristics: (1) They must exhibit favorable physiological and hygienic properties, including good thermal conductivity and air permeability, breathability, moisture absorption, radiation resistance, stain resistance, and heat resistance, while maintaining an appropriate weight. (2) Their aesthetic quality must be appealing, meeting consumers’ increasingly high aesthetic expectations in terms of luster, hand feel, dyeability, and durability. (3) Apparel materials must also be practical, offering excellent performance in toughness, elasticity, abrasion resistance, formability, water resistance, resistance to embrittlement, protection against insect damage, mold resistance, lightfastness, and shrinkage resistance.

　　4. Definition and Properties of Textile Fibers — Fibers are defined as filamentous materials whose length is at least a thousand times greater than their diameter, with diameters typically ranging from a few micrometers to several tens of micrometers, and which possess a certain degree of flexibility. In nature, fibers come in a wide variety of materials and forms; however, not all fibrous materials are suitable for spinning into yarns or weaving into fabrics. Only those fibers that meet the performance requirements of textile fabrics—both in terms of end-use applications and processing techniques—are classified as textile fibers.

　　5. Properties of Textile Fibers — Textile fibers must possess the following six properties: (1) They must exhibit adequate physical and mechanical properties, capable of withstanding specified levels of tensile, torsional, and frictional forces. (2) Their length and fineness must meet the requirements of textile processing, enabling them to interlock and form yarns. (3) Textile fibers should be flexible and possess a certain degree of elasticity—easily deformable yet able to recover their original shape effectively. (4) They must be poor conductors of heat, providing a degree of thermal insulation. (5) They must have appropriate moisture-absorbing and air-permeable characteristics, facilitating the absorption of perspiration and supporting dyeing and printing processes in textiles. (6) They must demonstrate chemical stability, exhibiting resistance to light, heat, acids, alkalis, and other environmental factors.

　　6. Classification of Textile Fibers — There are many types of textile fibers, which are generally divided into two major categories. The first category comprises familiar natural fibers such as cotton, wool, silk, and linen. These are fiber materials that grow naturally in the environment and can be directly spun into yarns and woven into fabrics; hence they are called “natural fibers.” Natural fibers are further classified according to their origin into plant‑based fibers and animal‑based fibers. Plant‑based fibers like cotton and linen have cellulose as their primary chemical constituent, so they are also referred to as cellulosic fibers. Animal‑based fibers such as wool and silk contain protein as their main chemical component, and are therefore known as protein fibers. The second category is synthetic fibers. Synthetic fibers are textile fibers produced by chemically processing natural or synthetic polymers. Depending on the raw materials used and the manufacturing processes involved, synthetic fibers are subdivided into man-made fibers and synthetic fibers. Man-made fibers are derived from natural polymers—such as wood pulp or short cotton fibers—and are manufactured through chemical processes to mimic the characteristics of natural fibers like cotton or wool; examples include rayon. In contrast, nylon, vinylon, polyester, and others belong to the synthetic fiber family. These are made from raw materials such as coal, petroleum, and natural gas, which are first converted into basic chemical intermediates and then further processed via complex chemical methods to yield textile fibers.

　　7. Classification of Fabrics — Clothing materials are diverse, with hundreds or even thousands of varieties. Despite their myriad forms, they are systematically categorized according to specific criteria. By composition, fabrics are classified into cotton fabrics, woolen fabrics, linen fabrics, silk fabrics, and synthetic fiber fabrics; by color, they are divided into undyed fabrics, plain‑dyed fabrics (also known as solid‑color fabrics), printed fabrics, and yarn‑dyed fabrics.

　　8. Properties of Cotton Fabrics — Cotton fabric is produced through numerous processes, including spinning and weaving, using cotton fibers. Thanks to the many excellent properties of cotton fibers, cotton fabrics exhibit superior moisture absorption, thermal insulation, and breathability, providing comfortable wear. However, they have certain drawbacks: they are not resistant to sunlight, have relatively poor acid resistance, and are prone to mildew and deterioration.

　　9. Properties of Linen Fabrics — The principal properties of linen fabrics are as follows: (1) They exhibit excellent strength; among natural fibers, hemp fiber boasts the highest strength, with ramie offering the best overall strength, and they also demonstrate good resistance to abrasion and tensile stress. (2) Linen fabrics possess favorable insulating properties and relatively good heat resistance. (3) They absorb moisture effectively and have strong water‑repellent characteristics; however, their elasticity is the poorest among natural fibers, making linen fabrics prone to creasing and wrinkling. Therefore, after washing, they must be starched or ironed to maintain their shape.

　　10. Properties of Worsted Fabrics — The primary raw material for worsted fabrics is wool fiber, with sheep’s wool accounting for approximately 95–97% and camel hair and goat hair making up only 1–3%. Since wool constitutes the main component of worsted cloth, its properties are largely determined by those of wool, and the key characteristics of worsted fabrics reflect wool’s inherent qualities. The principal properties of wool fabrics are as follows: they exhibit excellent moisture absorption, low thermal conductivity, and superior heat‑retaining performance. Based on the textile manufacturing process and the fabric’s visual attributes, worsted fabrics are classified into fine worsted and coarse worsted types. Fine worsted fabrics, also known as combed worsteds, are produced from high‑quality wool spun into combed yarns; these fabrics typically use finer yarn counts and are woven after doubling the yarns. They are characterized by high density, a tightly woven structure, a smooth and lustrous surface, clear patterns, vivid dyed colors, a soft hand, a smooth and crisp body, good elasticity, and resistance to soiling. Coarse worsted fabrics, or carded worsteds, incorporate a proportion of combed short fibers or offcuts in their raw materials. These fabrics are made with coarser yarns and are usually woven using single strands. Their surfaces undergo napping and raising, resulting in an indistinct pattern, a thick and substantial texture, and a fuzzy surface that provides excellent warmth.
