Understanding Technical Terms in Nonwoven Fabrics and Textiles

Nonwoven fabrics and textiles are widely used in various industries due to their unique properties such as durability, water resistance, and softness. However, the technical terms used in nonwoven fabrics and textiles can be confusing for many people. In this article, we will provide an overview of some commonly used technical terms in nonwoven fabrics and textiles, including fiber types, weaving techniques, meltblown technology, and nanocellulose.Fiber types refer to the different materials used to make nonwoven fabric. Commonly used fibers include polypropylene (PP), polyethylene (PE), polyvinylidene fluoride (PVDF), and polyamide (PA). Weaving techniques involve the arrangement of fibers into a fabric structure through various patterns such as plain weave, twill, and satin. Meltblown technology involves blowing small particles like glass beads or metal oxides into the fabric stream to create microfibers which improve the filtration efficiency of the fabric. Nanocellulose is a type of nanomaterial that can be added to nonwoven fabric to enhance its water resistance and softness.In conclusion, understanding technical terms in nonwoven fabrics and textiles is essential for choosing the right product for specific applications. By familiarizing yourself with common fiber types, weaving techniques, meltblown technology, and nanocellulose, you can make informed decisions when selecting nonwoven fabrics and textiles for your needs.

Nonwovenfabrics are a type of textile product that have gained immense popularity due to their various applications in industries ranging from healthcare to consumer goods. These products are produced by dissolving fibers in a solvent solution and then extruding the solution through a die to form a flat, non-ribbed sheet. Nonwoven fabrics are often used as substitutes for traditional woven textiles in applications where they offer superior properties such as high strength, moisture resistance, and ease of cleaning. In this article, we will discuss some of the key technical terms commonly used in nonwoven fabric manufacturing and provide an overview of the industry.

1、Fiber

Fiber is the basic structural element of a nonwoven fabric. It can be derived from natural sources such as cotton, bamboo, or hemp, or synthetic materials such as polypropylene, polyamide, or polyester. The choice of fiber depends on the desired properties of the final product, such as durability, softness, or water resistance.

2、Degrease/Sanitizing treatment

This refers to the process of removing impurities or contaminants from the fiber before it is used to produce the nonwoven fabric. This is typically done using a chemical solution that dissolves the impurities, leaving only clean fibers behind. The purpose of degrease/sanitizing treatment is to ensure that the final product is free from harmful substances and meets regulatory standards for hygiene and cleanliness.

3、Meltblown Technology

Meltblown technology is a process used to create microfibers from large globules of polypropylene or polyamide. These tiny fibers are then spun into webs that can be used to manufacture nonwoven fabrics with improved filtration properties, softness, and texture. Meltblown technology is commonly used in applications such as air filter media, surgical dressings, and disposable face masks.

4、Spun Bonded Technology

Spun bond technology is a method of producing nonwoven fabrics by tightly spinning together short fibers of different types or lengths. This results in a continuous sheet of fabric without any distinct edges or seams. Spun bonded nonwovens are commonly used in applications such as wipes, cleaning cloths, and packaging materials.

5、Cutting Machine

A cutting machine is a tool used to cut the nonwoven fabric into specific sizes and shapes. There are several types of cutting machines available, including laser cutters, shears, and rotary cutters. The choice of cutting machine depends on the desired output format and precision requirements.

6、Sewing Machine

A sewing machine is a tool used to stitch together two or more layers of nonwoven fabric to form a structured product. There are several types of sewing machines available, including automatic sewing machines and hand-held sewing machines. The choice of sewing machine depends on the desired production speed and accuracy.

7、Die-cutting Machine

A die-cutting machine is a tool used to cut out specific shapes or designs from a piece of metal or plastic material using a sharp blade. In the context of nonwoven fabric manufacturing, dies can be made from various materials such as steel, aluminum, or silicone to create intricate patterns and designs. Die-cutting machines are commonly used in applications where precise shapes and designs are required, such as in medical device packaging or industrial labels.

8、Weaving Machine

A weaving machine is a tool used to create complex weave structures by interlacing threads or filaments between two or more warp wires. In the context of nonwoven fabric manufacturing, weaving machines can be designed to produce a wide range of weave structures, including plain weave, twill weave, satin weave, or double knit. Weaving machines are commonly used in applications where intricate weave structures are required, such as in carpeting or upholstery materials.

9、Woven Fabric Production Process Overview

The production process for woven fabrics typically involves several steps, including yarn drafting, spinning, weaving, finishing, and packaging. In the case of nonwoven fabrics, some steps may be omitted or modified based on the specific application requirements. For example, meltblown technology may be incorporated into the production process to improve filtration efficiency or add texture. Once the nonwoven fabric has been manufactured, it may be further processed to enhance its mechanical properties or extend its lifespan through treatments such as flame retardant coatings or anti-microbial coatings.
