Nonwoven fabrics are broadly defined as sheet or web structures bonded together by mechanical entanglement, chemical, thermal, or other means. Unlike traditional fabrics, the fibers are not first converted to yarn and then woven or knitted into a fabric. Instead, a porous sheet or web is made directly from separate fibers. The process of manufacturing nonwovens is made up of two basic steps; 1) web forming, where loose fibers are laid out on a moving porous belt, or drums to create a uniform sheet, and 2) web bonding, where an adhesive or entanglement process is applied to bond the laid out fibers together to create a stable web, or sheet, of material. This course covers some of the different web bonding processes which are used.

At the end of this module, you will be able to:

  • List the three general classifications of web bonding used to manufacture nonwovens
  • List the three different techniques for apply binder to a nonwoven web
  • Describe solvent bonding
  • Describe thermal bonding
  • List some of the techniques for heating and bonding a nonwoven web
  • List the three general types of mechanical bonding
  • Describe the two general types of finishing processes
  • List some of the benefits that can come from nonwoven finishing

The following key questions are answered in this module:

What are the three broad classes of bonding use to create nonwoven materials?
Nonwovens can be bonded together using chemical, thermal or mechanical processes.

What are the advantages of using foam to apply binder to nonwoven materials?
Applying binder as a foam leads to higher production rates and lower drying costs than binder application by web immersion. Foam allows low application rates without the need for a containment enclosure which is required by the spray application technique.

How does thermal bonding work?
Thermal bonding works by heating a web and partially melting polymeric fibers, allowing them to bind to each other or to other fibers in a blended material.

What are three mechanical bonding techniques?
Nonwovens can be mechanically bonded together by needlepunching or spunlacing, which are entanglement processes, or by stitchbonding which uses woven threads to help hold fibers together.

What is one advantage of spunlacing?
Spunlacing uses high pressure water to entangle fibers and can be used to create surface patterns in the final web.

Below is a transcript of the video sample provided for this module:

Most of the polymers used in the spun-melt process create fibers that do not wet and are inherently water-repellent or hydrophobic. Many nonwovens are used in diapers, wipes, and other hygiene-related products. For these products, liquid transfer and absorbency are essential to how they function. One of the most important finishing coatings is the addition of a rewetting compound, which converts the sheet into a hydrophilic material, which is one that wets and allows water to pass through. This is typically done by passing the bondage sheet over a roll wetted with the rewetting compound, or a surfactant. After the application, the sheet must be dried before being wound on the parent roll. Other coatings used include antistatic compounds, softeners, and additives to enhance product performance and customer satisfaction.

Sorry, we're missing some information

How do I log in to watch a video that I have already paid for?

Easy! Moments after you purchase your pay-per-view (PPV) course, you'll receive an email with login details. Just click the link and log in with your user name and password and you're on your way!

I would like to have some of my employees take 5 of your driving related courses, how can i set this up?

We're in the process of making bulk purchases and purchases for multiple users easier. But for now, you can order multiple courses and just let us know who you'd like to assign courses to. With an email for each user, we can set up their training plans and make sure everyone gets the eLearning assignments they need.

How can I get your paper-making courses for free?

Well, we can't blame you for asking... And while we're a for-profit company, there are situations with students and certain educational organizations where we can help out with a selection of eLearning. However, our online courses are extremely economical. And our paper industry courses are in very high demand. So, without knowing more about your situation, we think you'll get loads of value from the $39 you'll spend on any of our premium courses.

Do you have eLearning in Portuguese?

Yes, we do! And in addition to primary English narration, we produce many courses in a growing number of languages, including Spanish, Chinese, Dutch, German, Italian, Japanese, Korean, Polish, Russian, Tamil, and Thai.

I'm unemployed, but I really like your eLearning. Do I get a certificate when I complete a course?

Yes! All of our courses allow you to print a completion certficate upon successfully passing the integrated test at the end of eLearning. In the future, we'll have badges for you to use in your LinkedIn profiles.
