Made To Last: Why We Make Our Air Socks The Way We Do


At Prihoda, we design all our products from first principles. We carefully select the scope, features, materials, and every detail that makes each product something we can be proud of. This includes the manufacturing methods used for each element. Prihoda has chosen a range of production processes and techniques designed to achieve the best possible results and preserve all the benefits of using fabric ducting.

How do we make our fabric ducts and diffusers?

These are some of the techniques we use in our manufacturing process:


Manufacturing methods: seam sewing of Prihoda fabric diffuser

With textile ducting, sewing represents the bulk of the production process. A duct is only as strong as its weakest seam; that’s why it’s so important to sew the seams well. We use double seaming techniques to achieve a textile strength of 900N at the fabric joints. Sewing is not just for duct seams either: the zippers are also sewn in, as are all nozzles with a diameter above 80mm.
Used for: duct seams, large nozzles, zippers
Advantages: strong seams and attachments

Sonic welding

Manufacturing methods: closeup of sonic welded fabric nozzle on fabric diffuserWe use sonic welding to attach our smaller nozzles onto the ducts. The vibration generated by sound waves creates friction between the nozzle and the duct, causing them to join and form a strong bond. Because both surfaces are made of the same textile material, this method results in firmly attached nozzles that never fall out, melt, or wear down the surrounding material. Pockets, such as those used in our SquAireTex diffusers, are also attached using sonic welding.
Used for: small nozzles, pockets, SquAireTex
Advantages: reliable results, very quick, forms a strong bond

Laser cutting

Manufacturing methods: lasering microperforations on Prihoda air sock. We use lasers to make all our perforations, from the tiniest microperforations to the biggest sizes. And for good reason, too. Laser cutting works exceptionally well with our textile material. It produces very smooth cut edges with no fraying and, therefore, no fibre shedding. Perfect for cleanrooms and anywhere with increased sanitary requirements. It also gives excellent dimensional accuracy and precise positioning, essential factors in our diffuser designs. After all, the airflow pattern made with 3mm perforations is not the same as that made with 4mm perforations. Laser cutting affords us the flexibility to create a truly bespoke airflow distribution every time.
Used for: all perforations, including microperforations
Advantages: clean edges, high precision

Why in-house?

We choose to manufacture in-house to ensure the highest quality standards. By using our own production facilities, we can rapidly identify opportunities for improvement of our manufacturing methods and products. We can also commit to responsible production practices, never compromising on our core values.

Standards we follow: ISO 9001:2015 (quality management), ISO 14001:2015 (environmental management)
