1 thing is certain when it comes to blinds cord - one day it
will wear out.
Preferably, of course, you want the wear to be slow and the
blind cord to last as long as possible.
So let's see what the options are and what is the best
choice when you are looking for a new cord for your blinds. We'll look at
material, cord thickness and color options.
Nylon, polypropylene (PP) and polyester cord
Blinds cord is often offered without specifying what
material the cord is made of. We choose polyester as Venetian blind cord because it is
strong and UV resistant. Nylon is also often offered, because it is very strong.
But..it is sensitive to UV light and that has 2
disadvantages:Especially
since blinds hang just where there is a lot of light, it is extra
important that a cord is UV resistant.And that makes nylon the less good
choice.
Polypropylene is also regularly sold as Venetian blind cord.
Mainly because it's a cheaper option than nylon and polyester, which is why it
can be offered cheaply. People who are price sensitive mainly look at that and will
then choose the polypropylene blind cord.
But this cord is not as strong and not as UV resistant as
polyester.
Cheap in this case is expensive, because the cord will wear
out faster and so you will consume more of it.
Plus you lose a lot of time if you regularly have to replace
your blind cord has to replace. Sin.
Electric blinds and blind cord
If you have electric blinds, you still need cord for rolling
them in and out.
When rolling in, the motor turns so that the blind cord is
twisted on a bushing, thus rolling the blind in.
The blind can be rolled down again, as the motor allows the
cord to unwind again.
In an electric blind,there are two louver cords.
One that tilts the slats. It lies loose over the bush, in
such a way that it can tilt the slats, but does not turn any further. but does not rotate further.
Because the motor works this way, you also never see
electric blinds with ladder tape.
The cord that pulls the slats up is attached to the roll-up
box with a knot and is thus rolled in and out.
This is the cord you will usually need to replace. With an
electric blind, this will generally be less often, due to the
constant force and run-in speed, so there will be less
friction.Less friction means less wear and tear.
Venetian blind size and choice of blind cord for electric
blinds
The larger the blind, the thicker the cord should be.
To determine which cord you need, you can look at the blind
body.
If it is 25 mm to 35 mm, then a cord of 1.0 to 1.3 mm will
be enough. If you have a wooden blind with a tray of 50 mm or larger,
then a cord of 2.5 mm will be the right choice.
Not sure which blind cord you need?
Here's how to make the right choice:
- Aluminum Blinds - 1.1 to 1.7 mm diameter
- Wooden Blinds - 2.5 mm diameter
- Flyscreen / mosquito net systems - 1.1 mm diameter
Construction of Venetian blind cord
Venetian blind cord is made of braided polyester with a
core from 1.7 mm diameter. Below that, it is hollow braided
because the diameter is so small.
Polyester is one of the most hard-wearing and UV-resistant
types of rope.
Available in white and black.
0.8 mm diameter polyester is also often used as louver cord,
even though it is not specifically made for that purpose.
This cord is available in many colors; on reels of 90 meters
