What kind of bag material is polyurethane?

Bags made of genuine leather are beautiful, durable, but very expensive. In search of an alternative to natural material, designers turned to polyurethane, which has excellent characteristics. Bags made of this material are very practical, durable and cheaper than products made from natural raw materials.

What kind of material is polyurethane?

German chemist Bayer Otto Georg Wilhelm in the 30s of the XX century in the laboratory synthesized a new polymer called polyurethane. It turned out to be a material with a huge range of applications, and its industrial production was soon established in Germany. Now such products are widely used in many industries and in everyday life. One of these uses is sewing bags.

What bags are made of polyurethane?

Recently, a new type of polyurethane called PU 100 has appeared. On product labels, it is indicated under this name or as polyurethane 100 . Sometimes it is positioned as eco-leather.

In fact, this is her excellent imitation. The bottom layer really consists of genuine leather, but with various flaws, tears, and polyurethane is placed on top, which in appearance is indistinguishable from expensive natural raw materials. The advantage of PU-leather is increased elasticity, strength, softness, frost resistance, moisture resistance.

This material inspires renowned designers to create designer collections of bags. Global manufacturers of accessories use PU leather as the basis for sewing fashionable and stylish handbags that are more practical than natural materials and look great.

Material durability

The unique properties of polyurethane allow it to easily replace rubber, rubber, plastic and even metal in many products. Its ability to operate under extreme mechanical loads is used in many industries.

We note its positive qualities as a material for sewing bags:

  • increased strength and elasticity of PU products;
  • resistance to deformation, ultraviolet radiation, microorganisms and moisture;
  • abrasive stability and, as a consequence, low abrasion of the PU surface;
  • highest resistance to aggressive environments: gasoline, various acids, organic solvents and oils do not affect PU-skin;
  • long term of operation.

Important! Polyurethane retains its unique properties and demonstrates tremendous wear resistance in the temperature range of -60 ° C to + 80 ° C.

How to care for her?

Synthetic materials do not require as careful care as is necessary for the skin. Everything is simpler here. Polyurethane is quite undemanding to operate and attention is paid to it only periodically .

The main points of caring for a polyurethane bag are as follows:

  • surface contamination - if liquids such as tea, coffee, juice, milk are spilled on the bag, melted ice cream gets in, just wipe this place with a damp cloth, and then again with a dry one;
  • in the same way the bag is cleaned of dust and other fresh contaminants;
  • complex stains are removed with ammonia or a solution where technical or medical alcohol and water are taken in a ratio of 1: 1. Such use of alcohol is possible because the material is synthetic and does not fear the dehydration of the surface and drying out, as is the case with the skin;
  • old stains of organic origin are removed using skin cleansers.

Important! To extend the life of the polyurethane bag, periodically treat its surface with special water-repellent impregnation for leather products.

How to remove creases on a bag made of polyurethane?

Improper storage can cause bruises and creases on the bag. In this form, you can’t go anywhere with her. Urgent need to seek a panacea for ills. There are several ways to get rid of such troubles:

  1. using a steamer (or an iron with this function). The surface of the bag is processed at a certain distance from the product itself with the help of steam discharged from the device with a minimum temperature. Condensation formed is immediately wiped with a cloth. If the creases are deep, then from the wrong side the hardest places are processed in the same way ;
  2. using the "steam bath". The bag is suspended for half an hour above a basin of hot water, from the surface of which moisture evaporates. Bruises will straighten out faster if you place a heavy object inside the product that slightly pulls the polyurethane down;
  3. using the press. Lightly dampened and leveled by hands surface is covered with a heavy flat object. Previously, something the same heavy and flat is placed in the bag. Bruises are between the two layers of the press. Soak for several hours, occasionally checking readiness. Dry naturally ;
  4. using oil. The folds treated with petroleum jelly, glycerin or castor oil will become softer and gradually straighten out over a couple of days. This technique will improve the overall appearance of the product. Processing is carried out not only in places of creases, but also on the entire surface completely. The product left for several hours should be absorbed, after which at the final stage the surface is polished with a woolen or velvet cloth.
