Spunlace Definition:What is spunlace nonwoven Fabric?
Spunlace (Also called Hydroentanglement) is a bonding process for wet or dry fibrous webs made by either carding, airlaying or wet-laying, the resulting bonded fabric being a nonwoven.
It uses fine, high pressure jets of water which penetrate the web, hit the conveyor belt (or “wire” as in papermaking conveyor) and bounce back causing the fibres to entangle.
Spunlace non woven fabric used short staple fibers, the most popular is viscose(38mm*1.67dtex) and polyester staple fibers(38mm*1.56dtex).
Sometimes Polypropylene (PP) also used in spunlace production.
Some other raw material, such as cotton, tencel,chitin etc. These fibers are more natural and they are from plant or animal, which is more expensive.
That is all about spunlace meaning you want to know.
Spunlace Technology :
A spunlace productive line is several machine parts contains, like mixer machine, carding machine, water jets etc.. To invest a spunlace machine is big.
The local China spunlace nonwoven machinery are mainly from Feilong, Zhengfangji etc.
The famous one may be “ANDRITZ” in Europe.
Based on technical reason, imported machine is better than Chinese machine, both output and fabric quality.
Nowadays the most spunlace non woven fabric manufacturers are from US, Europe,China and Turkey, Vietiam, India and Indonesia also have the spunlace machines in currently years. But China should be the most complete types and export the most quantity every year.
Hznonwoven now has 2 imported machine and 1 local machine, satisfied to different customer requirement.
The Characteristic of Spunlace Nonwoven
Flexible entanglement, does not affect the original characteristics of the fiber, does not damage the fiber.
Appearance is closer to traditional textiles than other nonwovens.
High strength, low fluffy.
High moisture absorption, rapid moisture absorption.
Soft, good shape
Various of Patterns
No adhesive reinforcement, washable
Also to produce the spunlace fabric, it is a big investment as mentioned before, the lines is very long and covers an large area.
Spunlace nonwoven Fabric is an important type of non woven fabric.(see what is non woven). The Spunlace process is a nonwovens manufacturing system that employs jets of water to entangle fibers and thereby provide fabric integrity. In last article, we have a photo to show the spunlace process:
In fact, With the development of spunlace nonwoven technology currently, we have some new spunlaced technology, one of the most important is woodpulp spunlace fabric. See the woodpulp spunlace process as below:
Woodpulp Spunlace Fabric now is popular and can replace some normal spunlace fabric, this fabric have 2 types:
Woodpulp Polyester Non woven Fabric & Woodpulp POLYPROPYLENE Non woven Fabric
These wood pulp non woven fabric is cheaper and also a good material for spunlace wipers.
Type of Spunlace Non woven Fabric
Based on the different lapping machine, spunlace have 2 types: Parallel lapped Spunlace Fabric & Cross Lapped Spunlace Fabric. What is the difference of Parallel lapped Spunlace Fabric & Cross Lapped Spunlace Fabric? The main difference is their fabric strength.Take 40gsm 100% polyester spunlace fabric for example, we see their data sheet as below:
The first table is cross lapping spunlace, which MD & CD is both higher than parallel lapping spunlace fabric. For easy understand, we have a photo to show you.
The parallel lapped spunlace can easy tear straight with its vertical direction, and cross lapped spunlace is not so easy to tear, you can not tear it in a straight line. On this occasion, parallel lapped spunlace is mostly used for wet wipes, and cross lapped spunlace are more widely used as dry wiping cloths or leather etc.
Application of Spunlace Non woven
First of all, spunlace non woven fabric is mainly used for wipes: such as home, personal, beauty, industrial, medical wipes, etc.
Too many Wipes both dry and wet are made by spunlace fabric.
Second, medical using is another major market for spun lace fabric: such as disposable surgical clothing, surgical cover cloth, surgical tablecloths, surgical aprons, etc;
And also wound application materials: bandages, gauze, Band-Aid, etc.
Third, spunlace fabric can make for clothes, for example clothing lining, baby clothes, training clothes, carnival night disposable color service, all kinds of protective clothing etc.
At least, it also decorative fabrics such as car interiors, home interiors, stage decoration, etc
How to check spunlace fabric quality?
Some customers told us that they received a wrong or lower quality spunlace non woven fabric. Then how do you check you received the right quality spunlace fabric? It is easy to test by the lab or costs money to by a 3rd party to do that. But here we show you the way to test in very easy way which you do by yourself.
The most important for spunlace fabric is its composition, as viscose fibers is usually more expensive than polyester fiber, viscose made the spunlace better absorbent and higher quality for wiping.
The most easy way to test the blend of viscose & polyester is burned the fabric:
See the fabric after burned:
You can see the obvious difference during the burning.
More polyester the fabric will burn more quick and it is not easy to exterminate.After burning, there is a black induration. But 100% viscose after burning it is only gray,no induration. So burn faster and more induration, then the fabric contains more polyester.
