Hot Air Through Non Woven Fabric vs. Spun-Bonded Non Woven Fabric
Both hot air through non-woven fabric and spunbond nonwoven are raw diaper material.
Different manufacturing processes give them different characteristics. Their main uses of them are also a bit different. Next, let's show you some basic questions about hot air through non-woven fabric.
Hot air non woven is to use the hot air on the drying equipment to penetrate the fiber web after the fiber is carded, so that it can be heated and bonded together.
What is hot air through non-woven fabric?
The process of belongs to a type of hot rolling non woven fabric manufacturing process. After the fibers are carded, the hot air through non woven fabric is used to penetrate the web through the hot air, so that it can be bonded by heating to generated nonwoven fabric.
Hot air non-woven is to use the hot air on the drying equipment to penetrate the fiber web after the fiber is carded, so that it can be heated and bonded to form air through nonwoven fabric.
Hot air through nonwoven fabric belongs to a type of hot rolling nonwoven fabric. After the fibers are carded, the hot air through nonwoven fabric is used to penetrate the web through the hot air, so that it can be bonded by heating. The generated nonwoven fabric.
Hot air bonding process:
Hot-air bonding refers to a production method in which hot air penetrates the fiber web on the drying equipment to be heated and melted to produce bonding. The heating method used is unreasonable, and the properties and styles of the products produced are also different. Generally, products made by hot-air bonding have the characteristics of fluffy, softness, good elasticity, and strong warmth retention, but their strength is low and they are easy to deform.
Application of hot air through nonwoven fabric use:
Hot-air adhesive products have the characteristics of high bulkiness, good elasticity, soft hand feeling, strong warmth retention, good air and water permeability, but their strength is low and they are easy to deform. With the development of the market, hot-air adhesive products are widely used in the manufacture of disposable products with their unique styles, such as baby raw material diaper, adult incontinence pads, sanitary napkin fabrics, napkins, bath towels, disposable tablecloths, etc.; thick Type products are used to make cold-proof clothing, bedding, baby sleeping bags, mattresses, sofa cushions, etc. High-density hot-melt adhesive products can be used to make filter materials, sound insulation materials, shock-absorbing materials, etc.
Differences between hot air through nonwoven fabric and spun-bonded non woven fabric:
Hot air through nonwoven fabric and Hot-rolled nonwoven fabric are not spunbonded nonwoven fabrics, they are nonwoven fabrics of thermal bonding method, and their raw materials are all short fibers. Spun-bonded non woven fabric is long fiber but its raw material is plastic chips.
spun-bonded non woven fabric: After polymer is extruded and stretched to form continuous filaments, the filaments are laid into a web, and the web is then bonded by itself, thermally bonded, chemically bonded or mechanically reinforced to make the web Become nonwoven fabric.
How to distinguish between hot air through nonwoven fabric and spun-bonded non woven fabric?
1. Hand feeling difference
The most direct way is to touch hot air through top sheet non woven fabric baby diaper with your hands, it will feel softer and more comfortable, spun-bonded non woven fabric will feel harder.
2. Gentally pull
After getting the baby diaper, gently pull up on the top layer of the baby diaper. Hot air through nonwoven fabric can easily pull out silk. If it is Spunlace nonwoven fabric, it is difficult to pull out the whole silk
