Effect of chemical additives on softness components of hygiene paper

Abstract

Chemical additives are used singly or in combination to impart functionality to hygiene paper (suggested). In particular, in the hygiene paper making process, dry strength agent, wet strength agent, softener, and other are widely used. The effects of chemical additives on the softness components were evaluated. In the case of surface softness, there was no change in MMD according to the addition of dry and wet strength agents. The MMD (mean deviation from the average friction of coefficient) was decreased by adding a softener, which is the purpose of its addition to the hygiene paper making process. The softness and wet strength were improved when the wet strength agent was added before the softener. In addition, lotion treatment was applied to the surface of tissue paper. The surface softness component of non-silicone-based lotion was similar or improved, which may overcome the problems of silicon-based lotion.

An Innovative Computational Strategy to Optimize Different Furnish Compositions of Tissue Materials Using Micro/Nanofibrillated Cellulose and Biopolymer as Additives

“…Formulation 4, with the incorporation of both additives, presented higher structure strength improvements by 77% compared with formulation 1. This result was corroborated by the results of the literature as the addition of CMF and chemical additives in the tissue structures improve strength properties of these products [ 13 , 25 , 27 ]. These additives promoted an increase in the surface area of the tissue structures due to the micro/nanofibrils and consequently formed stronger and more stable structures through inter-fiber interaction and hydrogen bonding [ 27 ].…”

“…In addition to the modification of fiber pulps, chemical additives are used to modify properties or improve the production process for different materials. Different chemical additives used in the tissue paper industry are designed and applied according to different needs such as dry strength agents, wet strength agents, softeners and lotions [ 13 , 14 ]. Usually, these additives are cationic as the fibers carry negative charges and they are also more effective in much lower concentrations than anionic polymers.…”

X‐ray diffraction, scanning electronic microscopy, and Fourier transform infrared spectroscopy analysis of toilet paper

“…[1][2][3][4] Allergies can be attributed to formaldehyde, lanolin, and benzocaine composites, which are commonly found only in moist toilet paper. On the other hand, bleach products, such as ClO 2 , H 2 O 2 , NaOH, MgSO 4, and others [5][6][7] are used to produce toilet paper. In addition, paper fillers, such as kaolin, CaCO 3, and TiO 2 , used to improve the paper mechanical properties, [8] can also be present.…”

“…At last, since the paper tensile of stiffness is related to the paper softness [14] and both are related to the different types of the paper components (types of fibers, fillers, bleaches, and softeners), [6,7] tension stress-strain measurements have also been carried out in the five different toilet paper samples in order to try to correlate it with the spectroscopy and XRD measurements.…”

Computational Simulation Tools to Support the Tissue Paper Furnish Management: Case Studies for the Optimization of Micro/Nano Cellulose Fibers and Polymer-Based Additives

“…The additives incorporation is also a strategy to optimize the performance of the enzyme in the tissue field, because they improve the enzymatic activity rate, allowing for a lower end-use enzyme application rate. The polymeric additives improve the tissue softness and/ or absorption properties, maintains or increases the paper strength properties, which can provide energy and cost savings [17][18][19][20]. However, balancing softness and strength properties in tissue paper production is not easy, as actions required to maximize softness are often in conflict with the ones needed to improve strength [3,7,9,10].…”
