Protective gloves are used every day for a great many activities in a variety of industries. They can be found everywhere from the cleanroom to the testing laboratory, the foodstuffs industry to the chemical industry, and even at the hair dresser's. At the TechTextil 2011 international trade fair from May 24 – 26 in Frankfurt am Main, Germany.
Bayer MaterialScience is presenting Impranil brand polyurethane (PU) dispersions that can be used to coat the textile substrate of lined gloves quickly and easily. Protective gloves made with these products are free of plasticizers and allergenic proteins. They are also tough, abrasion-resistant and very comfortable to wear.
“The grippiness of the glove surface can be precisely adjusted – from sticky to dry and flexible – by the choice of the PU dispersion and the formulation,” says Rolf Irnich, a textile coatings specialist at Bayer MaterialScience. This also applies to fabric-free disposable gloves, which can also be manufactured from PU dispersions. Gloves based on Impranil XP 2772 are very resistant to alcohol-based cleaning agents and solvents.
Gloves based on PU dispersions can be produced on conventional molds in dip processes. “The temperatures required here are not as high as those needed to produce gloves made of conventional materials such as latex and nitrile,” adds Irnich.
If the production process is based on a textile glove, the glove is first dipped into a coagulating agent and then dried for roughly three minutes at 100 °C. It is then dipped in a waterborne PU paste, dried for five minutes, soaked for ten minutes at room temperature, dried again at temperatures up to 100 °C and voilà, the protective, odor-free and resilient coating is finished.
