The nonwoven fabric subcategory of the textile industry is one of the most recent and exciting new fields to emerge. The industry of non-woven fabrics was slow to get started in my country, but it has made significant progress since then. When they were first being developed, non-woven materials were utilized almost exclusively in the apparel industry for the production of accessories.
As a result of the rapid development of the social economy as well as science and technology, an unending stream of new products and new technologies of non-woven fabrics are emerging. These products and technologies change with each passing day, and the scope of application is becoming an increasingly wider range.
Non-woven fabrics, or simply non-woven fabrics, are the correct terms to use when referring to this type of cloth. The GB/T5709-1997 standard is the national standard in my country. According to the "Textile Nonwovens Terminology," nonwovens are defined as follows: aligned or randomly organized fibers, formed by friction, cohesion, or adhesion, or a combination of these three processes. sheets, webs, or batts, excluding paper, woven, knitted, or tufted felts, wet-laid felts, and wet-laid felts.
It simply orients or randomly arranges textile staple fibers or filaments to form a web structure, which is then reinforced by mechanical, thermal bonding, or chemical methods because it is a fabric that does not require spinning and weaving. This is because it is a fabric that can be made without these processes.
It is possible to break down the manufacturing process of non-woven fabrics into the following stages:
1. Carding and finishing the fibers; 2. Forming the fibers into a web; 3. Fixing the web of fibers; 4. Subjecting the web to heat; 5. Performing any necessary finishing.
Non-woven fabrics can be divided into the following categories according to the factors that led to their production:
(1) Spunlace non-woven fabric: a high-pressure fine water jet is sprayed onto one or more layers of fiber webs to entangle the fibers with one other, which in turn strengthens the fiber web. This process can be repeated as many times as necessary to achieve the desired result.
(2) Heat-bonded non-woven fabrics are created by adding fibrous or powdery hot-melt adhesive reinforcement materials to the fiber web. This causes the fiber web to be heated, melted, and then cooled in order to reinforce it into a cloth. Heat-bonded non-woven fabrics can be used in a variety of applications.
(3) Pulp airlaid non-woven fabrics are also known as dust-free paper and dry-laid non-woven fabrics. These fabrics are made from pulverized wood pulp. It does this by employing a process known as air-laid, which separates the fibers of wood pulp into individual strands. Next, it makes use of airflow to concentrate the fibers on a web-forming curtain, after which the fibers are woven together to form a fabric.
(4) Wet-laid non-woven fabrics: The fiber raw materials that are placed in the water medium are broken down into single fibers. Then, different fiber raw materials are mixed together to make a fiber suspension slurry, which is then transported to the web-forming mechanism, where the web is reinforced while it is still in the wet state. cloth.
(5) Spunbond non-woven fabric: After the polymer is extruded and stretched to form continuous filaments, it is arranged into a web, and the fiber web is bonded or mechanically reinforced to become a non-woven fabric. This method is used to make spunbond non-woven fabric.
(6) Melt-blown non-woven fabric production consists of the following steps: polymer input, melt extrusion, fiber formation, fiber chilling, web forming, and reinforcing into cloth.
(7) Needle-punched non-woven fabric is a type of dry-laid non-woven fabric. This non-woven fabric is made by punching holes through it. The effect of the needle puncturing the web of fluffy fibers results in the web being transformed into cloth.
(8) Stitch-bonded non-woven fabric is a type of dry-laid non-woven fabric that uses the warp-knitted coil structure to reinforce the fiber web, yarn layer, non-woven material (such as plastic sheeting, etc.), or their combination. This type of non-woven fabric can also be called stitch-bonded non-woven fabric. Non-woven.
Non-woven fabrics can be made from a broad variety of fiber raw materials, including cotton, hemp, wool, asbestos, glass fiber, viscose (rayon), and synthetic fibers. Cotton is the most common of these materials (including nylon, polyester, acrylic, polyvinyl chloride, vinyl Wait).
Cotton fibers, however, are no longer the predominant component in the manufacturing of non-woven fabrics; in their stead, other fibers such as rayon have taken over this role.
Non-woven fabrics are a new type of environmentally friendly materials that are flame-retardant, moisture-proof, breathable, elastic, light in weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, inexpensive, and recyclable.
In addition, non-woven fabrics are rich in color, which allows for more design options. extremely general.
Because of their high filtration efficiency, insulation, heat insulation, acid resistance, alkali resistance, and tear resistance, non-woven fabrics are most commonly used in the manufacturing of filter media, sound insulation, electrical insulation, packaging, roofing, and abrasive materials. This is because non-woven fabrics are resistant to acid, alkali, and tear. product. In the industry that deals with things that people use on a daily basis, it can be utilized as a core material for things like apparel, curtains, materials for wall decoration, diapers, travel bags, and so on. It is possible to utilize it in the production of surgical gowns, hospital gowns, masks, sanitary belts, and other items related to medical and health care products.
Non-woven materials used in a variety of applications
1. Geosynthetic materials
Geosynthetics are a high-tech, high-value-added industrial textile material that may be utilized in a variety of different applications. Spunbond geotextiles, staple fiber needle punched geotextiles, hot melt bonded geotextiles, geonets and grids, geomembranes, and composite geotextiles are the primary types of nonwoven geotextiles. Other types include composite geotextiles. In geotechnical construction, the purposes of geotextiles include anti-seepage, filtration, drainage, isolation, and strengthening of the material being constructed.
2. Filtering material made of non-woven materials
In today's world, filtration materials have emerged as an extremely useful and essential category of consumer good. Non-woven filter material, which is a new type of filter material, is gradually replacing traditional textile filter material due to its distinctive three-dimensional three-dimensional network structure, uniform distribution of pores, good filtration performance, low cost, and many different varieties. It is currently the product of filter medium that holds the position of market leader. incredibly quick in speed.
3. nonwoven textiles with applications in the medical and hygienic fields
The development of medical non-woven fabric is one product that has the potential to advance. It makes the most of the benefits that fiber possesses as a material for use in healthcare and is the result of new industrial disciplines that have emerged as a result of the combination and intersection of a number of different technologies and fields of study.
Included in this category are surgical gowns, protective garments, disinfection wraps, masks, diapers, civilian wipes, wipes, wet wipes, magic towels, soft towel rolls, beauty goods, sanitary napkins, sanitary pads, and disposable sanitary cloths.
4. Agricultural nonwovens
Agricultural non-woven materials feature a minimal investment, a long service life, and good results. The dissemination of information regarding agricultural non-woven fabrics is helpful in disseminating information regarding agricultural modernization. Matting, heat insulation, heat preservation, wind barrier, fruit protection, pest management, seedling growing, sowing, covering, and other agricultural applications are the primary purposes for agricultural usage.
5. textiles made of non-woven materials for use in apparel
The non-woven adhesive lining that is used for clothing possesses the qualities of being lightweight, soft, having a low cost, having a wide variation range of thickness and thickness, having a strong adaptability, having a non-directional arrangement of fibers, having a large elasticity, and being easy to be compatible with a variety of different fabrics. This includes the lining, the adhesive lining, the flakes, the styling cotton, and various synthetic leather foundation textiles, among other things.
