NEWBUSI NG4118 series ——Hot air non-woven fabric in Spunbond

updatetime:2021-06-11 17:04:02

# Nonwoven

We have repeatedly compared the characteristics and application of spunbond nonwoven and hot air nonwoven. Generally speaking, hot air nonwoven fabric has the characteristics of high bulkiness, good elasticity, soft feel, strong warmth retention, good air permeability and water permeability, but its strength is low, easy to deform, and the price is usually higher than spunbond nonwoven. Since spunbond nonwoven is directly spun into a web from polymer particles and heated and pressurized by rollers, it has the advantages of excellent mechanical properties, excellent tensile strength, elongation at break and tear strength, etc. But it is soft Degree and air permeability are not so good. Both of them have their own advantages and disadvantages, so is there a nonwoven fabric that combines the characteristics of the two at a reasonable price? Yes! NEWBUSI NG41 cotton soft nonwoven series!


If everyone isn’t familiar with NG4118, then you should have heard of " parallel bicomponent " more or less. The figure below shows the manufacturing principle of NG4118:
 


The parallel bicomponent fiber is an A\B structure with different left and right materials. The principle is to cause the two materials to shrink to different degrees to produce spiral crimps, making them fluffy, soft and elastic. (There are many structures and cross-sectional shapes of bicomponent fibers, and the parallel bicomponent is only one of them)

 

Features of NEWBUSI NG4118

Due to its unique manufacturing principle, NG4118 combines the advantages of hot air nonwoven and spunbonded nonwoven while weakening the shortcomings of the two, and has obvious advantages over the two.

 The following chart shows the physical performance comparison between NG4118 and hot air & spunbond under the same weight:


◆It can be seen from the above figure that NG4118 has better transverse strength than hot-air nonwoven , which means that AB spiral cotton has better dimensional stability than hot-air nonwoven  in actual operation.


◆As can be seen from the above picture, in the softness test, NG4118 AB spiral cotton is softer than the other two nonwoven fabrics, but in fact NG4118 is also very soft.

 



◆The above pictures are the comparison tests of wear resistance of NG4118 AB spiral cotton on two non-woven fabrics after grinding 60 cycles under a 9KG pressure hammer. It can be seen that after wear, NG4118 has little difference with hot air fuzz. Comparabled to spunbond, the fiber length is almost the same, so the wear resistance is good.

In addition to the above 3 features, NG4118 also has the following advantages:

◆Since NG4118 is a pure PP raw material, no matter it is ultrasonic bonding or thermal bonding, it does not affect the production speed (take stretch pants as an example, usually the hot air material is about 300 pieces per minute, while NG4118 can reach 400-580/min)

◆If NG4118 is applied to the outer waist of stretch pants, the special pressure roller design combined with the characteristics of flocking, the touch after gluing is better than the hot air non-woven fabric, and the cost is lower.



Applications of NG4118

It is hard to imagine that NG4118, which has high bulkiness and super softness, is also a kind of spunbond fabric, which completely breaks the stereotype of spunbond, such as rough hand feeling and not skin-friendly. Due to the manufacturing process of NG4118, it can be applied not only to the outer waist circumference of stretch pants, but also to the outer waist circumference of menstrual trousers, the bottom layer of diapers and the sides of sanitary napkins.

NEWBUSI NG4118 is between spunbond non-woven and hot air non-woven. Under the same weight, NG4118 is double thicker than ordinary spunbond. It is softer, fluffy and more wear-resistant than ordinary spunbond, and it is not inferior than hot-air non-woven fabrics, the current price is lower than hot-air nonwoven, which is very cost-effective. It can be said that the bicomponent structure is the next important direction in the field of non-woven fabrics, and it is also a trend. Lets wait and see how it will develop in the future.
