Special handling items
Ligare is a high-performance conductive composite yarn created by a special composite spinning technology.
More carbon black than the current conductive yarn is placed on the conductive layer, and the effect is high static elimination in any environment regardless of the material used. In addition, it is a new material that can maintain its performance against physical stress such as washing and friction, and can maintain stable conductive performance.
Ligare yarnEnlarged cross-sectional view of
In rigare yarn, the conductive resin is exposed in three places on the yarn surface, and high conductivity is created on the yarn surface.
Other companies' products have one or two parts where the resin is exposed on the surface.
It has three contact surfaces and exhibits high conductivity performance compared to other companies' products.
Since it can be twisted with other fibers, the range of use is expanded.
Ligare Conductivity Features
1, There is almost no dependence on the temperature and humidity of conductivity.
2, Can be mixed with almost any fiber.
3, Excellent durability and semi-permanent effect.
4, Sufficient conductivity can be obtained even when mixed in small amounts in woven and knitted products.
Handling notes
-Because both the conductive layer and the protective layer are polyester, care must be taken in alkaline treatment.
・ Although the mixing ratio varies depending on the purpose and environment, the effect can be obtained with 0.2% to 2% for woven and knitted general clothing and 0.1% to 1 % for carpets.
-The conductive performance depends on the spacing of the conductive threads when woven and knitted in addition to the mixing ratio. When developing the fabric, setting the width spacing to 15 mm or less, preferably 10 mm or less, shows the static elimination effect by corona discharge.
-When conductive yarn is used on the surface of woven and knitted fabrics, it is recognized that the effect is also applied to the other surface.
Technical feature details
Ligare is a black polyester that is a side-by-side type in which two components, a conductive layer in which highly crystalline polyester is mixed with conductive fine particle carbon at a high concentration and a protective layer made of general polyester, are compositely bonded in the process of melt composite spinning. It is a conductive composite fiber.
The conductive layer is connected at the center of the fiber and has three or more exposed parts on the side surface, so charge transfer and diffusion in the axial and diametrical directions of the fiber are easy.
Moreover, self-elimination by corona discharge has a great effect.
Because the surface exposure of the conductive layer is low and the protective layer is general polyester, the strength, friction and durability are not inferior to those of general yarn.
Also, because both the conductive layer and the protective layer are polyester, they have excellent compatibility, and the impact has the feature that peeling and falling off due to friction are extremely small. ..

The closer the order of the Charged charge amount table is, the less likely it is to be charged, but the farther it is, the easier it is to be charged.
Fur and silicone rubber are separated, so they are easily take on electricity.
Custom-made fabrics and knitting are also possible.
It can also be processed into T / C by combining yarns such as polyester yarns and cotton yarns.
Various woven fabrics are available.
As for the characteristics of conductive fibers, the wider the contact area, the more effective it is, but the antistatic effect is also limited.
If you expect 100% static elimination, you must ground the ground.
The resin part on the thread surface is more than that of other companies'threads, and the antistatic effect is about 3 times that of other companies' threads. By reducing the amount of conductive yarn used, the manufacturing cost of the product can be reduced.
About 10% of the conductive resin on the surface of other companies' products is exposed on the surface of the yarn, and 30% of the rigare yarn is exposed on the surface of the yarn.
There are some products that do not prevent 100% static electricity.
The Harm of Static Electricity
Static electricity causes various problems. By taking measures against static electricity in various places, various problems can be prevented.
Reference Example
Semiconductor and liquid crystal industry ⇒ Packages, internal circuits (circuit destruction), characteristic deterioration (reduced yield)
Equipment (malfunction or damage to transistors, etc.) Packaging materials (attraction of dust)
Glass panel ⇒ (Breakage of glass during manufacturing)
Electrical and electronic components ⇒ (circuit, device destruction (circuit malfunction) (computer stop working)
(Robot malfunction)
Fibers ⇒ (poor twisting of raw yarn) (yarn tangles) (yarn breakage)
Film ⇒ (dust adhesion) (wrapping around rollers) (static discharge) (source of arrival, electric shock, pinhole formation)
(Products sticking to each other, repulsion, explosion)
Medical treatment ⇒ (fire/explosion in oxygen tank, ignition of anesthetic glass)
Powder ⇒ (aggregation, scattering, poor sifting, static electricity discharge, powder explosion, electric shock)
Transport pipes ⇒ (dust adhesion, static electricity discharge, ignition source, electric shock)
Paper ⇒ (ink splatter, printing defects, paper crimping, offset)
There are the following types of charges :
Contact electrification : Electrification that occurs when objects come into contact with each other
Frictional electrification : Electrification that occurs when objects rub against each other
Peeling electrification : Electrification that occurs when removing clothing or peeling off a film
Flow electrification : Electrification that occurs during the transportation of liquids or powders, filtration, etc.
Collision electrification ⇒ electrification that occurs during pneumatic transport of powder
Electricity is electricity that is flowing, while static electricity is electricity that is "stationary" - a state in which electricity remains within a substance and the object is either positively or negatively charged.
Will there be an excess of positive charge?
Would there be an excess of negative charge?
The basic state of electrons is one positive and one negative
When something becomes charged, one of the charges increases, causing an imbalance of electrons, resulting in static electricity.
In other words, static electricity occurs everywhere.
It is clear that there are many situations in which static electricity can be suppressed by using conductive thread.
Static electricity builds up on the body and is discharged when the body comes into contact with other objects.
The graph below shows the pain felt during discharge.
Normally, the pain caused by static electricity is up to about 5kV, but anything over 6kV can cause considerable pain.
There are even more powerful static electricity that can occur between materials, which can cause powder explosions and deterioration of products.
Suppressing static electricity also makes it possible to reduce product loss.
The static electricity felt when wearing the mask is about 2000V.
The level of voltage that you can feel on the outside of your finger but does not hurt is 2000V, which is a voltage that you can feel instantly.
You will feel a voltage of 3kv or 5kv when touched, which can make you feel pain.
You will not feel voltages higher than this in your daily life, but it can occur on rare occasions, so be careful.
Depending on the application of the Ligare yarn, it is possible to eliminate the voltage within the range of values shown in this graph.
