Caption: The creator of the above label, Avery Dennison, says wet strength
starts with the adhesive.
For the determination of the wet strength
, samples of 50 mm width and a clamping length of 100 mm were soaked in water, dripped off and then measured immediately.
Dry strengths of all the adhesives were very good, but only the soy protein isolate has good wet strength
without PAE polymer (Table 1).
There is no systematic relationship between wet strength
and clay content for either subsoil or saprolite (Fig.
Tests have shown the wet strength
of Tork Premium wipers to be significantly higher than wipers made using other methods.
Bounty Basic has been designed to please those women by providing outstanding wet strength
performance at a great everyday value.
Besides this, we as producers look at the technical sides like how it performs on the machinery: particle retention, wet strength
The beat results were obtained in experimental manufacture by using fiber furnishes of 100-percent strong bleached sulfate pulps with the addition of melamine-formaldehyde resin to increase the wet strength
and titanium dioxide to produce the desired capacity.
Dr Sansom said: "This resin is added to tissues for example to give them wet strength
and make sure they hold together when you blow your nose.
Regular viscose fibre does not have high wet strength
but the polymeric variety of viscose fibre has this property also.
These include formaldehyde for use in manufacture of polymers, urea-formaldehyde concentrate for the fertilizer and resin industries, wet strength
resins for the paper-making industry, and specialty urea-formaldehyde, melamine-formaldehyde and phenol formaldehyde resins for a wide range of uses in both liquid and powder forms.
