The Influence Of Pith Cells On The Papermaking Characteristics Of Pulp From Bagasse, Miguel A. Cabrera

Paper Engineering Senior Theses

Literature Survey

Introduction

The fact that the need for paper products is increasing in an unparallel manner with the wood resources available at the United States market, has open the field for research studies in the development of new raw materials.

Bagasse has been a waste product submitted to intense laboratory investigation due to the fact that is a world available and relatively cheap fiber. Its use as a papermaking material has been investigated over a 100 years. Its development has been attacked by the different and contradictory opinions obtained from pilot plant runs and lack of knowledge techniques in …

Fiber Length As A Variable Influencing Wet Strength, Charles Elliott

Paper Engineering Senior Theses

It was desired to discover the influence of fiber length on wet strength obtained by the addition of a resin. The wet strength tests chosen were the tear and tensile, the retention of the resin was also measured. The resin used was melamine formaldehyde acid colliod.

The wet tensile showed no significant drop with decreasing fiber length until the fibers were cut very short. The wet tear was shown to be very sensitive to any change in fiber length. The retention of the resin was relatively unaffected by the fiber length.

The Influence Of Locust Bean Gum On The Strength Characteristics Of Handsheets Under Varying Ph Conditions. A Study Of The Effect Of Alum Or Hydrogen Ion Concentration, Robert J. Witters

Paper Engineering Senior Theses

A literature survey concerning the addition of locust bean gum to beaten pulp and the resulting strength characteristics imparted to handsheets through the addition of the gum has been undertaken. Although much literature can be found, hardly any detailed information can be extracted on the effect of alum or hydrogen ion concentration. Therefore, the aim of this paper is to draw some conclusion, through laboratory work, as to any possible change, due to pH or alum, in the strength characteristics of handsheets containing locust bean gum.

The first part of this thesis will be a brief review of work that …

The Loss Of Some Strength Characteristics Of Coated Magazine Paper As A Result Of Exposure To Elevated Temperatures, Hugh D. Burnie

Paper Engineering Senior Theses

Introduction

The purpose of this work is to investigate the effect that varying degrees of temperature have on the strength properties of coated magazine stock. Paper of this type encounters high temperature conditions primarily in the ink drying operations following the printing of the web. The strength with which the paper meets the cutting, folding and binding methods which follow the drying operation are of paramount importance to the printer. Throughout the work, attempts were made to assimilate conditions encountered in present day commercial practice.

Acid Treatment Of Pulp At Different Temperatures And The Resultant Change In Pulp Characteristics, Kent Dickerman

Paper Engineering Senior Theses

Literature Survey

The aim of this thesis is to investigate the acid treatment of pulp at different temperatures. In the experimental work, enough sulfuric acid is used to neutralize the mixture of pulp and water and thereafter reach in the pH range of one and eight tenths to two at atmospheric pressure. Temperatures during experimentation range from room temperature to 100° Centigrade.

A Study Of The Effect Of Avoidance On Stuttering Frequency In An Adaptation Situation, Theodore Ray Dixon

Masters Theses

A Study of the Effect of Avoidance on Stuttering Frequency in an Adaptation Situation

I Introduction

Much of the recent research related to stuttering has been concerned with the adaptation effect. The adaptation effect in stuttering refers to the phenomenon in which the frequency of stutterer continues to read the same passage aloud a number of times. During these readings each successive passage evidences fewer stutterings until a plateau is attained.

Much of the literature has ascribed great importance to avoidance mechanisms as maintaining causal factors. These avoidance mechanisms may be generally classified in two categories which are word avoidance …

A Comparison Of The Color Stability Of Certain Rosin Sizing Agents As Influenced By Light And Iron, Raymond L. Janes

Paper Engineering Senior Theses

A literature survey is presented concerning the yellowing of paper with age and the relationships of rosin, light, and iron as factors in inducing this discoloration. The recent chemical modifications of rosin which are applicable for use in the sizing of paper are investigated with the intent of discerning whether or not they exhibit sufficient improvement in color-brightness stability over that of natural rosin to warrant their use in certain high quality papers.

The experimental results indicated only one rosin modification, "Foral", a fully-hydrogenated rosin, having a marked advantage over natural rosin with regard to brightness stability as affected by …

Size Tests Applicable To Writing Surface Versus Aqueous Inks, Md. Mozammel Haque

Paper Engineering Senior Theses

Introduction

Some paper, because of their use requirements are required to be porous and absorbent to liquids, particularly water. Examples of these papers are paper towels, blotters and filter paper. Most papers, however, are required to be resistant to the passage of acquous liquids or vapor. Writing papers, moisture resistant bags, waxed paper and many other classes of paper too numerous to mention fall into the latter groups of papers.

The required degree of resistance to the penetration of aqueous liquids or vapors is brought about through the process of sizing. Sizing may be defined as the addition of materials …

The Problem and Its Background

Introduction

It is common knowledge that education consists of more than training for academic achievement. It consists of teaching whole individuals how to live effectively in their social environments. Although it is almost impossible to teach them all the skills directly they can be helped to learn through experience a great number of them for themselves. These view-points with respect to the teaching of students are held not only by a great number of educational authorities but are also part of the educational practice of a great number of teachers.

An Evaluation of the Universal Magnephot Densichron as a Reflectometer, Opacimeter and Color Analyzing Device

This paper is a report on the evaluation of the Universal Magnephot Densichron, an electronic photocell instrument developed for the photographic industry, for use in the paper industry. This instrument has been found to have several errors which make its use impractical for research work in the laboratory, but it can be used in paper mills for control purposes. If this used for this type of work certain precautions have to be taken as outlined. The major portion of this paper deals with the possibility …
