Non-woven fabric is a kind of non-woven fabric. It uses high-refractive-index slices, short fibers or filaments to form fibers through airflow or mechanical, and then is reinforced by spunlacing, needle punching, or hot rolling, and finally after finishing The new fiber products with soft, breathable and flat structure have the advantages that they do not produce fibrous debris, are tough, durable, and are silky and soft. They are also a kind of reinforcing material, and they also have a cotton feel, which is proportional to cotton fabrics and non-woven. Cloth bags are easy to form and cheap to manufacture.

advantage:

1. Lightweight: Polypropylene resin is the main raw material for production, with a specific gravity of only 0.9, only three-fifths of cotton, with fluffiness and good feel.

2. Softness: It is composed of fine fibers (2-3D), light spot-like hot-melt bonding molding. The finished product is moderately soft and comfortable.

3. Water-repellent and breathable: polypropylene chips are non-absorbent and have zero water content. The finished product has good water-repellent properties and is composed of 100% fiber. It is porous and has good breathability. It is easy to keep the cloth dry and easy to wash.

4. Non-toxic and non-irritating: the product is produced with FDA food-grade raw materials, does not contain other chemical ingredients, has stable performance, non-toxic, non-odor, and does not irritate the skin.

5. Antibacterial and anti-chemical agents: Polypropylene is a chemically passive substance, not moth-eaten, and can isolate the erosion of bacteria and insects in the liquid; antibacterial, alkali corrosion, and finished products do not affect the strength due to erosion.

6. Antibacterial properties. The product is water-removing, not moldy, and can isolate the erosion of bacteria and insects in the liquid, and is not moldy.

7. Good physical properties. It is made of polypropylene spinning directly laid into a mesh and thermally bonded. The strength of the product is better than that of ordinary staple fiber products. The strength is non-directional and the strength in the vertical and horizontal directions is similar.

8. In terms of environmental protection, the raw material used for most non-woven fabrics is polypropylene, while the raw material for plastic bags is polyethylene. Although the two substances have similar names, they are far from each other in chemical structure. The chemical molecular structure of polyethylene is quite stable and extremely difficult to degrade, so it takes 300 years for the plastic bag to decompose; and the chemical structure of polypropylene is not strong, and the molecular chain can be easily broken, which can be effectively degraded And enter the next environmental cycle in a non-toxic form, a non-woven shopping bag can be completely decomposed within 90 days. Moreover, non-woven shopping bags can be reused more than 10 times, and the environmental pollution after disposal is only 10% of the plastic bags.

Disadvantages:

1) Compared with woven cloth, the strength and durability are poor.

2) It cannot be washed like other fabrics.

3) The fibers are arranged in a certain direction, so it is easy to split from the right angle and so on. Therefore, the improvement of production methods is mainly placed on the improvement of preventing division.

Fabrics are designed and constructed to meet the requirements of different applications; however, all fabrics fall into one of two categories: woven vs non-woven.

Woven Fabrics

Woven fabrics are the most traditional fabrics constructed by weaving yarns together typically at 90° angles. The vertical fibers are called “warp” threads, while “weft” threads weave through the warp threads along the horizontal width of the textile. Woven fabrics can be created from a wide variety of materials and are most commonly used in clothing and various industrial applications. Most clothing fabrics and items, including shirts, pants, and even denim are all woven.

Advantages of Woven Fiber

When considering textile options, it’s essential to weigh the pros and cons of woven vs non-woven fabrics. Woven materials are usually the most cost-effective textiles for a variety of applications. These fabrics can be finished or treated with substances to give them attributes like waterproofing and breathability. They are also readily available and easy to source from a robust and wide-ranging supply chain. Woven fiber comes in a variety of weave types, and custom constructions can be easily engineered to suit various needs. Additionally, woven fabrics provide a wide range of high-performing physical characteristics.

Some industrial applications for woven fabrics include, but are not limited to:

• Composite material components (for example, aircraft internal / external reinforcement)
• Filtration membranes and materials for chemical processing applications
• Automotive applications (for example, insulation or sound absorption)

Non-Woven Fabrics

• PPE and uniforms for military personnel, divers, firefighters, law enforcement, etc.
• Strong safety harnesses and seat belts for recreational, automotive, and aerospace applications
• Upholstery materials for furniture
• Medical fabrics
• Consumer fabrics

Non-woven fabrics are textiles that have been created through a process of bonding fibers together, either by some kind of chemical adhesion, mechanical or heat treatment, or a combination of those. There is no weaving or manual construction involved. Although woven fabrics are usually stronger because of how they are constructed, non-woven fabric can be strengthened by bonding multiple layers or adding support backing.

Non-woven fabrics are long fibers that are bonded together by heat, chemical, or mechanical treatment. There is no weaving or manual construction involved. Non-woven fabrics have many different properties; including liquid resistance, being stretchable, better thermal insulation than woven fabrics, and can be resistant to bacteria. These fabrics can also be made stronger by adding a supportive backing. They also tend to be the more affordable choice, as these fabrics are less expensive to produce and quicker to manufacture. In most cases, woven fabrics are more durable and strong than non-woven. This is because woven fabrics are reinforced by thread crossing thread, which creates a strong barrier.

Advantages of Non-Woven Fiber

Non-woven fabrics are often more cost-effective and can be manufactured more quickly. The many advantages of non-woven fibers include resiliency, enhanced absorbency, improved washability, and bacterial protection. Non-woven fabrics can also be tailored to enhance certain features such as liquid repellency, impact resistance, flame retardancy, electrical insulation, and thermal insulation. Additionally, these soft and flexible fabrics offer improved filtering and sterility.

The versatility of non-woven fabrics makes them suitable for a wide array of industrial applications, including:

• Aerospace applications (such as exterior tiles on spacecraft)
• Acoustic insulation
• Thermal insulation
• Fire retardant mattresses and other fire-retardant materials
• High-temperature industrial filters
• Puncture and cut-resistant materials
• Synthetic and composite materials for industrial use
• Welding protection
• Wall coverings
• Trunk liners and vehicle seats

Woven vs Non-Woven

In summary, the choice between woven vs non-woven textiles hinges on specific needs and characteristics. Woven fabrics offer strength and durability, suited for traditional applications like clothing and industrial components. Non-woven fabrics, on the other hand, provide cost-effectiveness, absorbency, insulation, and more, making them versatile for industries such as aerospace, healthcare, and automotive. Both have their roles in meeting diverse textile demands.
