1. What is non-woven fabric?
Non woven fabric, also known as non-woven fabric, is a type of fabric that can be formed without the need for traditional warp and weft weaving techniques. The production principle is that oriented or randomly arranged fibers are combined with each other through friction, interlocking, bonding, etc., and finally made into sheet materials, fiber webs or flocs.
2. Types of non-woven fabrics
Non woven fabric integrates the processing technology of four flexible materials: textile, papermaking, leather, and plastic, forming a unique new interdisciplinary field. It covers various types of materials, such as hydroentangled non-woven fabric, wet or dry non-woven fabric, spunbond non-woven fabric, and synthetic leather based on sea island fiber materials. The process characteristics of these materials include short process flow, intelligent equipment, high production efficiency, fast production capacity, and wide applicability.
According to the web forming method and reinforcement method, non-woven materials can be further divided into the following categories: dry web forming, such as hot air method, needle punching method, water jet method, etc; Polymer extrusion into a web, such as spunbond and meltblown methods; And wet mesh forming methods, such as circular mesh method, inclined mesh method, etc.
3. Application of non-woven fabric
Non woven fabrics have a wide range of applications in multiple fields. Due to its technological characteristics and material diversity, it plays an important role in industries such as healthcare, hygiene, agriculture, and packaging. For example, in the medical field, non-woven fabrics are often used as materials for surgical gowns, masks, and protective clothing; In agriculture, it is often used to make coverings and soil conservation materials. In addition, non-woven fabrics also have environmental advantages, are biodegradable, and are environmentally friendly.
The uniqueness of non-woven materials endows them with a wide range of application space, and the diversity of their structure, appearance, and performance makes them shine in multiple fields. These applications can be roughly divided into two categories: disposable items and durable products. Next, we will explore in detail the applications of non-woven fabrics in various fields.
1) Health field
Non woven fabrics play an important role in the field of hygiene, and are widely used in incontinence products for infants, women, and adults, such as diapers, sanitary napkins, and care pads. In addition, non-woven materials are often used for tea bags, wiping cloths, wet wipes, and cosmetic materials.
2) Medical field
In the medical industry, non-woven fabrics also play an indispensable role. Surgical caps, surgical gowns, masks, shoe covers, bed sheets, and blood dialysis filtration materials are typical applications of non-woven fabrics.
3) Home Decoration
Home decoration is also an important application area of non-woven fabrics. Dust proof cloth, felt, wall cloth, decorative lining cloth, pillows, pillowcases, curtains, Simmons mattresses, and filter cloth all rely on the contribution of non-woven fabric.
4) In the field of agriculture
The agricultural sector also benefits from the diversity of non-woven fabrics. Crop cover cloth, leather base cloth, fur protective cloth, and root protection bags are all designed to protect crops and increase yields.
5) Industrial sector
In the industrial field, non-woven fabrics also have a wide range of applications. Geotextiles, filter materials, tapes, packaging materials, and fire-resistant materials all use non-woven fabric technology. In addition, automotive materials such as cabin liners and roofs often use non-woven fabrics.
6) Military industry field
Non woven fabrics are also widely used in the military industry. Protective materials such as cut resistant, bulletproof, and radiation resistant materials, as well as aerospace high-temperature resistant materials, anti-counterfeiting materials, and shielding materials, all demonstrate the excellent performance of non-woven fabric technology.
7) Other fields
In addition to the application areas mentioned above, non-woven fabrics also play a role in map fabrics, calendar fabrics, artificial fabrics, oil painting fabrics, and clothing linings. At the same time, artificial materials such as fluff, toe lining, heel lining, and underwear are often produced using non-woven fabric technology.
