Our standard range yarns are always in stock or can be procured at short notice. Low quantities of yarns from the special range are kept in stock, however, they can be procured for manufacture with a delivery lead time of approx. 1 - 3 months. Yarns not listed here can be procured for certain minimum quantities. 

Yarn counts

Normally, a yarn consists of a number of individual filaments or of individual fibres which are held together by twisting. Fibre and filament can have different cross-sections. The number of fibres per yarn length section can vary. Finally, those variations and the yarn manufacturing conditions also mean that the yarn cross-section does not have a constant size. It is therefore difficult to exactly measure the physical dimensions of a yarn in order to derive a fineness gauge.

In practice, the ratio between mass and length of a fibre, yarn or thread is used to specify the fineness. Two numbering systems are in use for the fineness: the weight numbering system and the length numbering system.

The weight numbering system and its units

Weight numbering, also referred to as titration, was introduced in the 1950s and is recommended for international usage. The fineness is defined as mass per length unit. According to this, the fineness specifies the number of mass units which are included in a determined length unit. The fineness is generally referred to as titre

The base unit is tex. It is defined as follows: 

  • tex = g / 1000 m; symbol: Tt

Example: If a 1000 m long yarn weighs 20 g, then the yarn count is 20 dtex.

tex is an internationally recognized SI-unit. tex is preferred in practical applications for fineness specification of spinning yarn and threads made from spinning yarn. Some derived units were allowed for reasons of mathematical simplification and exactness of the figures. 

  • decitex = g : 10,000 m; Symbol: dtex

This unit is mainly used for monofilaments, single filaments and multifilaments. 

  • milliex = mg : 1000 m or g : 1000 km; symbol: mtex
  • kilotex = kg : 1000 m or g : m; symbol: ktex

Apart from these units which are directly derived from tex, the older historic "International Silk Titre" (denier) is also still in use. It is, however, frequently or completely replaced with decitex in the filament area. 

  • denier = g : 9000 m; symbol: Td - or (den)

The tex system for the designation of linear masses of textile products is described in DIN 60 905, part 1.

Belt widths as well as panel widths of our stretch material require different machines. We have the following options depending on the product group:

  • ilira-stretch between 60 and 1200 mm
  • ilira-elastic between 20 and 120 mm
  • ilira-roll between 10 and 35 mm
  • ilira-tech between 4 and 115 mm
  • ilira-automotive between 4 and 115 mm

Just contact us if your desired width is not covered with our standard belts. If there are any options, then we will work on a solution with you.

Order values & minimum quantities


Minimum order value

We supply from our standard delivery range as of a minimum order value of € 200.  - also assorted shipments.


Minimum manufacturing quantities

The amount of work to upgrade a loom increases depending on the belt width. Therefore, belt manufacture only makes sense for all parties once a certain minimum quantity is achieved. Assume approx. 5,000 m to 10,000 m on our machines for simple items with fast turnaround times. More extensive tapes, heavy belts and special articles can be manufactured for you starting from 2,500 m.

The same applies to the unit ranges. Cutting and simple sewing jobs are possible starting at 100 units, since standard processes are used in this case. More extensive setup times for ultrasound and laser technology is only worthwhile for greater unit numbers. This also applies to more extensive setups on sewing workstations with matching insertion tools. 

As part of our offers, we also provide you with simple hand samples and similar items in possibly different width, thickness and colour free of charge. More extensive samples are invoiced with sample flat rates - contact us for details.

Delivery times


We deliver within...

  • 24 hours Express Delivery - order receipt by 12 noon from available range
  • 48 hours from our extensive standard range for delivery locations in Germany
  • 96 hours for international delivery for delivery locations in Europe

We agree suitable delivery times for make-and-hold-orders with you. We ensure repeated delivery from stock within this time frame. Special scenarios can of course be agreed with us.

Woven material which is not part of the standard range can often be realised within 6 - 8 weeks. In rare cases, special items from our belt range require 10 weeks manufacturing time. We will discuss this with you as early as the quotation phase.

Finished goods can usually be delivered within 3 weeks. Special productions or components with additional mounting parts always have to be coordinated separately in the event of an order. International procurement markets repeatedly cause unpredictable delays. 

Thermal finishing


We mainly process yarns made from synthetic multifilament fibres. The thermoplastic properties of these yarns can only be influenced in a certain temperature range. The changed parameters are preserved in the belt once cooled. This process is similar to ironing at home, just much more complex! We can influence many more parameters in the strip range.

With regards to product finishing we generally distinguish between two types of thermal product finishing:

  • Thermal stabilization
  • Thermosetting

Using heat, the belt is brought to a thermal sphere of influence for both process steps. The required temperature for the relevant process depends on the raw material and the belt itself. In any case, the finishing temperature is lower than the melt and decomposition temperature of the material.

Shrinking occurs during heating - we control this material shrinkage by defined tension on the belt. The difference between these two finishes is the duration of the set temperature and the force with which the belt is controlled.

  1. Thermal stabilization 
    During this process, a temperature is applied to the belt for a very short time and the material starts to change slightly. This brief heating up makes the belt surface smoother and softer. The rebound force of the belt increases which is comparable to "ironing". We reduce the stress differences within the belt construction with the retaining forces. The belt becomes visually calmer, its tensile dynamic properties more even. However, it is not possible to make changes to the expansion values of the belt due to the plant construction. 

  2. Thermosetting
    Similar temperatures are used for thermosetting as for thermal stabilisation. The temperature exposure time and the controlled cooling times are, however, much longer for this process. The surface becomes even smoother and the rebound behaviour is further improved.

    Longer temperature exposure times are possible thanks to our large thermosetting plant. With this plant we are able to influence the expansion behaviour of the belt thanks to greater, more exactly defined tensile forces.

    The belt can be shrunk in order to minimise subsequent shrinking when exposed to heat and to allow greater expansion when loaded. 

    The belt can be stretched in order to achieve shorter expansions when loaded.



My [KiiPER] storage net is too small for the markers in the drill template. Have I been supplied with a net which is too small?

No! The net comes out of the package "smaller" since it first has to be stretched to the right length. Stretch widths at a glance:

  • Net [S] has to be stretched by about 3 – 5 cm
  • Net [M] has to be stretched by about 5 – 7 cm
  • Net [L] has to be stretched by about 9 – 11 cm
  • Net [XL] has to be stretched by about 12 – 14 cm

 Further information can be found in our gallery in the [KiiPER] FAQ subsection - CLICK!


How can I remove my [KiiPER] without damaging it?

With some skill, you can make your [KiiPER] removable in three steps. For this purpose, prepare the panels as follows...

  • make 3 small incisions on each of the 4 hook positions on the inside of the panel (as seen from the net side)
  • the incisions have to broken out from the inside outwards
  • the cover can now be "unlocked" again using a screwdriver once the panel has been assembled

We have added a short instruction to the [KiiPER] FAQ subsection to make this clearer - CLICK!

With the exception of this option, it is not possible to dismantle the [KiiPER] without drilling the cover open. The storage net cannot be removed without tools and is therefore theft-proof and also suitable for public areas.


What can I store in my [KiiPER]?

The opening on the bottom of the [KiiPER] has been left intentionally. This means you can stow away more or even stick items through. Once you experienced [KiiPER], you will notice the many advantages.


Does the net wear out?

It is not a rubber net - rubber wears out! We use a technical elastomer. This is far more durable. If you should have a dent in the net because you stored something in it for a whole year, then simply use a normal hair dryer to remove the dent and make the net elastic once more - but be careful and don't heat it up too much!


Which [KiiPER] sizes are currently available?

The [KiiPER] sizes are currently available:

  • S – inner stretch width approx. 20 cm
  • M – inner stretch width approx. 27 cm
  • L – inner stretch width approx. 35 cm
  • XL – inner stretch width approx. 45 cm


What do I get when I order a package?

The delivery scope includes...

  • 1x net with sewn on net holders
  • 2x panels to fit the net
  • 2x covers to fit the net on the panel - can only be dismantled if destroyed
  • 1x drilling template
  • 6x metal screws 4.8x13
  • 6x wood screws 5x17


What are the different patterns of my storage net?

The net is currently only available in linear and chequered versions.


Is the [KiiPER] available in different colours?

Our current net range has the chequered and linear version in black, the linear version is also available in grey.


Do you have any installation ideas for me?

Naturally! [KiiPER] can be installed in any conceivable way. You can install the panel on the bottom and on top (vertical assembly), fit it to the ceiling or the floor or install it at an angle. Look for a free space - that's the space you can install your [KiiPER]!


Can I install the [KiiPER] without drilling?

No! A minimum of 4 drill holes - we recommend 6 - are necessary to install an original [KiiPER] net!

However: The net can be installed on an intermediate element (e.g. wooden board or plastic board) in order to avoid drill holes in the wall / caravan. This is then fitted in the desired space using assembly foam / double-sided tape / Velcro tape / silicone etc.


Can I install my storage net outside?

There is no reason why not. [KiiPER] is mostly weather-resistant and above all theft-proof. Protect it as well as possible against the sun - this will increase the durability.


How long will a [KiiPER] last?

It is impossible to give a general answer to this. The functional efficiency depends on its treatment. As long as [KiiPER] is not deliberately damaged, cut etc., then the net will not wear not. If you protect [KiiPER] against direct sun exposure like any other plastics, then [KiiPER] will last just as long as any other plastic product.
