Filament spunlace nonwoven fabric is a type of nonwoven fabric made from continuous filaments, where fibers are entangled and consolidated through a high-pressure spunlace process. It combines the high strength characteristics of filaments with the soft texture brought by the spunlace process. Here is a detailed analysis:
Types of Raw Materials: It mainly uses continuous filaments of synthetic fibers such as polyester (PET), nylon (PA), and polypropylene (PP) (different from short fibers). Among them, polyester filaments are the most commonly used due to their high cost performance and stable performance.
Structural Features: The filaments themselves are continuous. After being entangled by spunlacing, they form an irregular network structure. There are no obvious joints between the fibers, and the overall structure is more uniform and dense.
The core process of filament spunlace nonwoven fabric is "filament web formation + spunlace consolidation", and the specific process is as follows:
Filament Spinning and Drawing: Polymer chips are melt-spun to form continuous filaments, which are then mechanically drawn to refine the fibers and obtain a certain strength.
Web Formation: The filaments are dispersed through a filament splitting device and evenly laid on the web-forming curtain to form a loose filament web.
Spunlace Consolidation: The fiber web is transported to the spunlace machine. High-pressure water streams (usually with a pressure of 50-300bar) are sprayed onto the fiber web from the fine holes of multiple water jet plates, causing the fibers to entangle and interweave under the impact of the water flow, eventually forming a nonwoven fabric with a certain strength.
Post-treatment: Including dehydration, drying, calendering, winding, etc. Some products will undergo functional finishing such as hydrophilic, antistatic, and antibacterial treatments according to requirements.
High Strength and Tear Resistance: The structure of continuous filaments makes its tensile strength and tear strength much higher than that of short-fiber spunlace fabrics, making it not easy to break and more durable.
Soft and Delicate Touch: The spunlace process uses physical entanglement rather than chemical bonding or hot pressing, avoiding stiffness. The smooth surface of the filaments further enhances the softness and silky touch.
High Air Permeability and Moisture Permeability: The porous structure formed by fiber entanglement allows air and water vapor to circulate freely, making it particularly suitable for scenarios with high air permeability requirements.
Good Dimensional Stability: Filaments are not easy to shrink or deform. After spunlacing, the structure is stable and can maintain its original shape after washing or being stressed.
High Cleanliness: There are no chemical adhesives in the production process, and the filaments themselves have few impurities, making them suitable for fields such as hygiene and medical care that have strict requirements on cleanliness.
Hygiene Products: Such as high-end wet wipes, makeup remover pads, baby wet wipes, etc. Their softness, skin-friendliness, and non-linting properties are non-irritating to the skin.
Medical Field: Can be used to make surgical gowns, surgical drapes, medical masks, wound dressings, etc. The high strength and good air permeability help keep medical staff and patients comfortable, while also playing a role in blocking bacteria and viruses.
Personal Care: Mask substrates (especially suitable for carrying essence and fitting the skin), facial cleansers, etc., with a delicate touch and good water absorption.
Filter Materials: Utilizing its porous structure and filtering performance, it can be used in air filtration, liquid filtration and other fields, such as air conditioning filters, water purifier filters, etc., which can effectively filter dust, pollen in the air and impurities in liquids.
Industrial and Home Furnishing Materials: In industry and home furnishing, it can be used as wipes (such as clean room wipes in the electronics industry), decorative fabrics (such as wall covering substrates), etc., which are wear-resistant and easy to clean.
Comparison Dimension | Filament Spunlace Nonwoven Fabric | Short-Fiber Spunlace Nonwoven Fabric |
Raw Materials | Continuous filaments (no joints) | Cut short fibers (length 38-100mm) |
Strength | Higher (anti-stretching, tear-resistant) | Lower |
Linting Situation | Rare (filaments are not easy to break and fall off) | May lint slightly (short fiber ends are easy to fall off) |
Cost | Higher (filament raw materials and complex processes) | Lower |
Application Scenarios | High-end hygiene, medical care, filtration | Ordinary wet wipes, home cleaning, etc. |
Filament spunlace nonwoven fabric, with the combined advantages of "high strength + high softness + high cleanliness", occupies an important position in the field of high-end nonwoven materials, especially suitable for scenarios with high requirements on performance and experience.
