21 Citations | This implies that the paper strip can absorb fluids only at a certain maximum rate which decreases with time. |
In general can be inferred that the higher the porosity value of the paper the greater ability to absorb liquids on paper. | |
More absorbent towels may harbor more Staphylococci than less absorbent ones, and may serve as a transmission mechanism for the bacterium. | |
32 Citations | The expenditure analysis indicates that for the preferred functional form, the demand for ecolabeled paper towels is inelastic for environmentally conscious consumers. |
16 Citations | The results indicate that the Porous Plate and Sliding Block Methods have potential for measuring the moisture absorbency of towels. |
Thus, the study showed that nanoparticle selenium-coated paper towels may lead to an increased eradication of bacteria in a wider range of clinical environments and in the food industry, thus improving human health. | |
The present study provides evidence that the triphenylmethane dye (BG) present in green paper towels can migrate through the skin even when the exposure time is short (30-300 s). | |
5 Citations | The result showed that the maximum velocity and the amount of water absorption were greatly affected by the weft yarn density and the mean pile length in towels. Therefore, as the water absorbency of after breaching towels was controlled by changing the weft yarn density and the mean pile length, it can be used for the design of comfort towel. |
Used paper towels may contain high bacterial levels (>4.0 log CFU per towel) when hands are highly contaminated. |

What are the commercial absorbents?5 answersCommercial absorbents commonly used for the removal of acidic gases include alkanolamines such as monoethanolamine (MEA)and 2-(2-aminoethyl-amino ethanol) (AEEA). MEA is a commonly used chemical absorbent in gas treatment units, while AEEA has shown potential as an absorbent for capturing carbon dioxide (CO2) from atmospheric flue gases. AEEA offers high absorption rate and capacity for CO2, as well as higher cyclic capacity and lower regeneration energy requirements compared to MEA. Additionally, absorbent articles designed to provide a more pure end product may leverage plant-based materials in both wearer-facing and garment-facing layers. Polymerized, copolymerized, or vulcanized natural materials derived from vegetable or mineral sources can also be used as absorbents for the selective removal of organic chemical pollutants from gases, liquids, and solid compounds. Adsorbents consisting of filler granules and a binder can be used for adsorbing and/or absorbing organic and/or inorganic substances from liquid or gaseous phases.
How paper towels clean dirt?5 answersPaper towels clean dirt by using various techniques and materials. One method involves using a wet strengthening technology to combine long and short fibers at specific ratios, enhancing the paper's strength and durability. Another approach is to apply a layer of cream coating agent on the surface of the paper, which contains palm moisture preservation ingredients, resulting in soft and moist texture, smoothness, and skin-friendly effects. Additionally, disposable towels can be used with gentle wiping pressure to remove dirt while maintaining skin barrier function. The use of two-dimensional codes can also track and manage the cleaning process of towels, ensuring that only clean and quality-checked towels are used. Furthermore, paper towels can be made from raw wood pulp fibers, wastepaper pulp, protonated chitosan, and AKD, which improve the dry and wet strength of the towels and make them environmentally friendly and safe. Finally, some towels have an integrated cleaning agent in a pocket, which releases a cleaning solution when activated by water.
What are the different types of paper towels?4 answersThere are several different types of paper towels mentioned in the abstracts. One type is the sandwich type paper towel, which is made by layering wet paper sheets and waste paper sheets. Another type is a paper product that includes both hardwood fibers and softwood fibers, with the tissue containing a higher percentage of hardwood fibers. There is also a wet and dry dual-use paper towel, which consists of a wet towel layer and a dry towel layer separated by a plastic film. Additionally, there are paper towels made from raw wood pulp fibers, wastepaper pulp, protonated chitosan, and AKD, which are added to improve the strength and safety of the towels. Finally, there is an antibacterial paper towel made from traditional Chinese medicines, including cane syrup, wood pulp, bamboo pulp, and various herbal ingredients.

How to create absorbent material from fiber?5 answersAbsorbent material can be created from fiber using various methods. One method involves using cellulose from bagasse and combining it with ethylenically unsaturated monomers, free radical initiator, crosslinkers, and distilled water. Another method involves hydrolyzing waste polyacrylonitrile fiber by dissolving it in a solvent, adding lye, performing heating and hydrolysis reaction, and then separating and drying the resulting material. Additionally, a fiber laminate with excellent absorptiveness can be created by forming a top surface layer, a rear surface layer, and an absorption layer with dispersed porous particles. Furthermore, a metal fiber porous absorbent material can be prepared by ultrasonic cleaning, drying, surface leveling, sintering, and rolling metal fiber blank felts. Finally, an absorbent material for absorbent articles can be produced by embossing and cutting a semi-finished absorbent material product containing a fiber laminate.
