মেল্টব্লোউন ননওয়েভেন মেশিনগুলি মেল্টব্লোউন ননওয়েভেন কাপড় তৈরিতে একটি গুরুত্বপূর্ণ ভূমিকা পালন করে, যা তাদের লাইটওয়েট দ্বারা চিহ্নিত করা হয়, ছিদ্রযুক্ত গঠন এবং অত্যন্ত সূক্ষ্ম ফাইবার. These machines utilize high-speed hot air to attenuate and entangle extruded thermoplastic filaments, forming a web of fine fibers that is subsequently collected and processed.

Understanding Meltblown Nonwoven Machines

cof

Meltblown machine nonwoven fabric consists of several key components:

  • Extruder: This component melts thermoplastic resin pellets or granules, preparing them for extrusion through fine nozzles.
  • Distribution Plate with Nozzles: The molten resin is forced through thousands of tiny nozzles, creating a multitude of filaments.
  • Hot Air System: A high-velocity hot air system heats up as it passes over a chamber and is then directed onto the extruded filaments.

Key Parameters of Meltblown Machines

The performance and output of meltblown nonwoven machines are influenced by several critical parameters:

  • Nozzle Holes: The number and diameter of nozzle holes determine the fineness of the fibers and the fabric’s basis weight.
  • Air Temperature: Higher air temperatures result in finer fibers but can potentially damage the resin.
  • Airflow: Increased air velocity produces finer fibers but consumes more energy.
  • Resin Type: Different resins, such as PP, PE, and PET, are used based on the desired fabric properties.
  • Production Speed: Higher speeds allow for increased fabric production but may affect fiber fineness.
  • Width: The machine’s width determines the size of the nonwoven fabric produced.

Applications of Meltblown Nonwoven Fabrics

Meltblown nonwoven fabrics possess unique attributes that make them suitable for a wide range of applications:

  • Healthcare: They are extensively used in surgical drapes, gowns, masks, and swabs due to their high barrier properties.
  • Filtration: Meltblown fabrics serve as efficient filter media for air, liquids, and other applications, effectively removing particles and contaminants.
  • Apparel: These fabrics are utilized as interlinings and insulation layers in clothing, providing warmth and structure.
  • Wipes: Meltblown nonwoven fabrics are commonly used to produce wet wipes for personal and industrial cleaning purposes.
  • Acoustics: They are employed as sound insulation in buildings and vehicles, effectively reducing noise levels.
