role of spandex in diapers

Diaper is defined as “a basic garment for infants consisting of a folded cloth or other absorbent material drawn up between the legs and fastened about the waist” by Merriam Webster dictionary.

Now based on the requirement diapers are primarily used for infants and young children but they are also now used for elderly people and for adults suffering with mental or physical disabilities. Now-a-days people have started using them for pets too, so diapers have become an integral part of our lives.

Disposable diapers have now completely replaced the traditional re-usable diapers made of cotton fabric used earlier. Disposable diapers are mostly made using the following components and materials:

1) Polyethylene film

2) Polypropylene Non-woven Hydrophobic and Hydrophilic

3) Absorbent core – Wood pulp fluff

4) Super Absorbent Polymer

5) Elastane /Spandex fiber

6) Quick wicking layer

7) Adhesive Hot melts and Elastomeric

8) Fastening tape Stick type/Hook and loop type

9) Moisturizer lotions and fragrance lotions

10) Breathable/Cloth-like back sheet

Here we will focus on the role of Elastane /Spandex fiber in diapers.

In disposable diapers usually polyurethane or polyester foam elastics, and synthetic rubber or spandex elastics are used. But due to their properties now-days mostly spandex elastics are used.

spandex-journeyIn 1956, a spark was ignited in the form of the invention of a product which was supposed to be the alternative for “Rubber” in that time of war where rubber was getting scarce and expensive; this yarn was given the name of “SPANDEX”.

After a few years of its invention, the first ever use of spandex in clothing was in “Pantyhose” around 1960s. Then later in the ’60s, the spandex was used in swim-wear, due to its high stretch, flexible and comfort providing properties.

Wearing garments having spandex in them by French Olympic ski team for the 1968 Winter Olympic Games, lead to various designers to use it for the garments which need functionality (mainly sportswear).

Amongst various garments where spandex was used in the ’60s and 70’s here are a few prominent ones: women’s pantyhose, swimwear, wetsuits, cycling shorts, bra-straps, leotards, tights, aerobic wear, and athletic clothing.

Then by ’80s many of the prominent designers started to use spandex in fashion clothing and out came the garments like form-fitting dresses, women’s spandex bodysuits.

With the coming of 90’s the spandex use boomed in the garment industry now it was used is – body-shaping foundation garments, shirts, pants, dresses, shoes were made from spandex blends. Soon it progressed into men’s wear market.
