Classification and Inspection of Textile Products
Textile products are an essential part of our daily lives. From clothing to bedding, textiles provide comfort and protection in a variety of settings. However, the production of textiles can be complex and involves various stages of manufacturing. Therefore, it is important to classify and inspect textile products during their production process to ensure they meet quality standards.Textile classification involves categorizing textile products based on factors such as material type, texture, color, and design. This information helps manufacturers determine which steps need to be taken during production. Inspection is also critical in ensuring that textile products meet quality standards. Inspection methods may include visual examination, testing, and measurement.Visual inspection involves assessing the overall appearance of textile products, checking for defects such as holes, wrinkles, and stains. Testing may involve analyzing the chemical composition of the fabric or examining its durability under various conditions. Measurement techniques may include measuring length, width, and thickness of textile products.In conclusion, classification and inspection play a crucial role in ensuring the quality of textile products. By identifying potential issues early on in the production process, manufacturers can take corrective action and produce high-quality products that meet consumers' expectations.

Textbook Introduction to Textiles (Chapter 1): Textiles are a diverse range of natural and man-made materials that are used for clothing, bedding, shelter, and many other household items. They can be made from fibers such as wool, cotton, silk, synthetic fibers, or a combination of these. Textiles come in many different forms, including yarn, fabric, tapestries, embroidery, and weavings. In addition to their functional uses, textiles are also appreciated for their beauty, texture, and color. This chapter introduces the basic properties of textiles, their production processes, and the various applications of different types of fabrics. It also discusses the environmental impact of textile production and consumption.
Section 1: Introduction to Textile Product Classification (Page 2)
Textile products can be classified into several categories based on their properties, composition, and intended use. These categories include:
1、Natural Fiber Textiles: Made from natural fibers such as wool, cotton, silk, flax, hemp, jute, or ramie. These textiles are often soft, breathable, and durable. They are used for clothing, bedding, upholstery, and other household items.
2、Man-Made Fiber Textiles: Made from synthetic fibers such as acrylic, nylon, polyester, rayon, or polypropylene. These textiles are often stronger, more resilient, and easier to clean than natural fibers. They are used for clothing, bedding, insulation, and industrial applications such as filtration and packaging.
3、Textural Textiles: Produced by combining multiple layers of fibers or textures to create a unique visual effect. Examples include velvet, twill, satin, and corduroy. These textiles are often luxurious, comfortable, and resistant to wear and tear.
4、Knitwear: Created by interlocking loops of yarn using knitting needles or machines. Knitwear is often soft, warm, and flexible. It is commonly used for clothing such as sweaters, socks, and scarves.
5、Weaving Textiles: Made by interlacing threads or wires using a loom or other weaving machine. Weaving textiles are often strong, durable, and versatile. They are used for clothing, bedding, curtains, tablecloths, and many other items.
6、Printed Textiles: Decorated with patterns or designs using various printing techniques such as screen printing, dye sublimation, or embroidery. Printed textiles are often eye-catching and can express a wide range of emotions and ideas.
7、Specialty Textiles: Designed for specific purposes such as athletic wear, workwear, or medical uniforms. Specialty textiles may have special features such as moisture-wicking properties or anti-microbial agents.
Section 2: Fabric Properties and Characteristics (Page 3)
In order to classify textile products properly, it is important to understand their physical characteristics such as weight, thickness, texture, colorfastness, breathability, durability, and flame retardancy (if applicable). Here are some key terms related to fabric properties:
1、Weight: The amount of weight per square yard (or meter) of fabric. Lightweight fabrics are typically made from natural fibers such as cotton or linen while medium-weight fabrics are made from synthetic fibers such as polyester or rayon. Heavier fabrics are often used for outdoor wear or heavy furniture covers.
2、Thickness: The distance between two consecutive warp or filling threads in a woven fabric. Thicker fabrics require more warp threads to achieve the desired thickness and strength. Thinner fabrics may have fewer warp threads and may be suitable for light clothing or delicate items such as lingerie or curtains.
3、Texture: The feel or appearance of the fabric when touched. Examples include smooth (such as silk), rough (such as wool), fuzzy (such as flannel), or matte (such as cotton). The choice of texture depends on the intended use of the fabric and personal taste.
4、Colorfastness: The ability of a fabric to remain its original color after being exposed to various environmental factors such as sunlight, water, chemicals, or washing cycles. Some fabrics may lose color over time or become faded more easily than others.
5、Breathability: The ability of a fabric to allow air to pass through and circulate around the body without feeling hot or stuffy. Breathable fabrics are often made from natural fibers such as cotton or linen which allow sweat to evaporate more easily than synthetic fibers such as polyester which trap heat and moisture against the skin.
6、Durability: The ability of a fabric to withstand wear and tear over time without breaking down or losing its shape or structure. Durable fabrics may be more difficult to clean or maintain but can save money in the long run by reducing the need for frequent replacements.
Section 3: Textile Product Testing Methods (Page 4)
In order to ensure that textile products meet certain quality standards and regulations set by governments and industry bodies around the world, they must undergo various tests before they can be sold or exported. Here are some common testing methods used in textile product classification:
1、Weight determination: This method involves measuring the mass of a sample of fabric using a balance or other scale instrument. The weight is usually expressed in grams per square meter (g/m2).
2、Tensile strength test: This method involves stretching a piece of fabric until it breaks under tension using a tensile test machine. The force required to break the fabric is measured in newtons (N) or pounds per inch squared (psf). The higher the tensile strength number, the stronger the fabric is considered to be.
3、Tear strength test: This method involves ripping a piece of fabric along its length using a tear resistance test machine until it starts to fray or break apart at the seamline. The force required to rip the fabric is measured in N or psf again. A higher tear strength number indicates a stronger fabric that is less likely to unravel under stress.
4、Shrinkage test: This method involves exposing a piece of fabric to heat and then measuring how much it shrinks in both width and length after being washed or dried according to the manufacturer's instructions. The shrinkage rate is expressed as percent of its original size before washing or drying.
5、Colorfastness test: This method involves exposing a piece of fabric to various environmental factors such as sunlight or chemicals in order to determine how well it retains its color over time without fading or discoloring. The test is usually conducted using a specialized machine that simulates these environmental factors in order to evaluate the fabric's colorfastness performance.
