Stains should come out if you use 25% solution of ethanol. Rub gently and wipe dry to remove the rest of the detergent. Please, bear it in mind that some stains might not be completely removed from the cleaned surface. It depends on several factors like active dyers permanently migrating to the material surface, the material composition and finish, or chemical composition of dirt; it is also important how long the soiling has remained on the material surface.

You should pay particular attention to the generally available domestic cleansers whose components might react with the soiling and cause effect contrary to what was originally intended.

All materials produced by Sanwil Polska should be cleaned according to the laundry guide issued by Sanwil.

Remember that coated products made by Sanwil should never be cleaned with domestic cleansers and cleaning agents that are generally recommended for ‘eco-leather’.

All materials produced by Sanwil Polska should be cleaned according to the laundry guide issued by Sanwil.

A working sample is placed in a ring-shaped clamp fixing which keeps the flat surface of the tested sample face up, around its edges. The sample is rubbed across its surface, in a horizontal position, while the rubbing material consists of a wool piece of cloth with the particular rubbing parameters. The test is carried out at the constant pressure of 12±0,2kPa between the sample fixing and the rubbing surface. The sample moves across the rubbing surface in a shape of Lissajous figure.

The tested sample is subject to as many rubs as stated in the Product Card. The test stops after a particular number of rubs and the sample is checked for damages in a bright but not directly positioned light. Each tested sample is compared with a piece of the same kind of material which has not been subject to abrasion resistance test; the changes in its surface are assessed according to table 1 (below).

Abrasion resistance is tested on the basis of norm PN-EN ISO 5470-2: 2005 - Rubber or Plastics Coated Fabrics, Determination of abrasion resistance. Part 2: Martindale Abrader.
At least four pieces are cut out of different places of a tested sample. If a tested material has an irregular embossing or irregularly printed spots, each piece of material must be tested.

0 - No changes - Sample intact
1 - Vary small changes - The colour faded. The print (in case of printed materials) as well as the sample surface remain intact.
2 - Small changes - The colour faded. The print (in case of printed materials) partly or totally damaged. The sample surface intact or only a little disturbed.
3 - Medium changes - The sample surface damaged.
4 - Considerable changes - The sample surface totally damaged and the inner layer or
a foam disturbed.
5 - Complete damage - The product backing shows up.

It is a French symbol describing flammability of public places seats. AM 18 regulation (Spectacle) demands to fulfill two norms:
- NF P92501 and NF P92507 in M3 level
- norm NF D 60013 – pass

M1 and M2 symbols refer to the combustion test classification. They appear in the following norms:
- French norm NF 92-507, which refers to the testing methods depending on the thickness and kind of a tested material. Norms numbers from NF P 92-501 to NF 92-505 refer to fire safety, building materials, reaction to fire, and electrical burner. The norm assesses: dripping of the burning material, maximum burning time, and the destroyed surface of the burning material. On the basis of the results, the material is classified between M1 and M4, where M1 means the highest and M4 the lowest flammability resistance.
- Spanish norm UNE 23721-27, which refers to building and decorative materials, upholstery fabrics, reaction to fire, and electrical burner. Like the French norm, it also assesses the dripping and the destroyed surface of the burning material. On the basis of the results, the material is classified between M1 and M4, where M1 means the highest and M4 the lowest flammability resistance.

Upholstered furniture are subject to flammability test with the ignition source of:
- Smouldering cigarette (according to norm PN-EN 1021-1) – it is often incorrectly called ‘a cigarette equivalent.’ It is a regular cigarette without a filter tip, 70±4 mm long, weighing 1±0,1 g, with a diameter of 8±0,5 mm. A smouldering cigarette is put on the upholstered material surface and the material is tested for ignition. The whole cigarette must burn down.
- A match equivalent (according to norm PN-EN 1021-2) – it is a special ignition source of a gas flame with calorific value similar to a burning match; it is basically a burner (a pipe) with an inner diameter of 6,5 mm supplied with butane gas. When the gas source is set according to the norm, we should achieve a 35 mm long flame. The flame is put against the material for 15 seconds and it is tested if the product catches fire.

Sanwil Polska Sp. z o.o. has a flexible R&D department that can work up a new material or a new colour desired by the customer. The product can be designed on the basis of the required specification, matching a pattern sample, or according to the material purpose. The more details our R&D is familiar with, the sooner the material will be ready, and the customer will be more satisfied with the ready product.

The chemical laboratory allows us to match the colour of every sample sent by the customer (according to RAL or PANTONE colour catalogue).

Gluing is a very popular way of joining plastic, rubber and other non-metallic products. Taking into consideration the general physical and chemical parameters, dissolubility and the tolerance of the substances, it is easy to draw a conclusion that high synthetic materials should be joined with an adhesive made of the same high polymers.

The following adhesives are recommended:
- Phenolic adhesive
- PVC-based adhesives
- Acrylic acid based and metacrylic acid based adhesives
- Epoxy adhesives
- PU-based adhesives
- Natural and synthetic rubber based adhesives

Out of a vast choice of adhesives available on the market, PU and PVC-based adhesives are the most suitable substances to join PVC coated materials with other plastic products, wood or metals.

PVC-based adhesives allow to join PVC materials with metals, wood and plastic products. They are solutions of PVC and organic solvents (ethyl acetate, butyl acetate, dichloroethane, methyl chloride, acetone). They adopt ready-to-use liquid forms or jelly-like masses, which turn into liquids when heated, and can be used for cold pressing of soft and hard PVC. Those substances provide thermoplastic joints resistant to water, acids, alkalis, mineral oil or petrol.

The majority of PU-based adhesives are binary. The binding takes place as a result of a chemical reaction between the adhesive elements. Its liquid form turns into the solid one and this process is irreversible. The adhesive components are selected according to the purpose. PU-based adhesives are suitable for joining products which are usually difficult to glue, like hardened rubber phenol or melamine thermoset plastic mouldings. They are used for joining the soft PVC, polyisobutylene, polyamides and thioplasts, as well as for joining natural leather with wood and plastics. This type of adhesives is also perfect to stick together polyamides, or polyamides with PVC products, phenoplasts, fluoropolymers and polystyrene. PU-based adhesives create joints resistant to different atmospheric and temperature conditions, water, weak acids and alkalis, oil, fat and petrol.

If you want to keep your upholstered furniture original structure and appearance, it is necessary to clean it in an appropriate way. All materials produced by Sanwil Polska should be cleaned according to the laundry guide issued by Sanwil. You should never use domestic cleansers and the ones that are generally recommended for ‘eco-leather’.

Coated materials should be cleaned in neutral pH (7) soap solution applied with a soft sponge or a damp cloth. Rub gently and wipe dry to remove the rest of the detergent. In order to keep the original colour and shine level, the procedure should be repeated every month.

The upholstered furniture will not lose its original colour and gloss if you do not expose it the direct contact with a heat source like a heater or a fireplace, which have a negative impact on the coated fabric visual and aesthetic parameters.
