NEW MULTICLIENT PROJECTS AT THE PTS TECHNIKA
SYNTHETIC FIBRE PULPS • VEGETAL FIBRE SUBSTITUTES
NATURAL FIBRE COMPOSITES • IMPROVED FORMABILITY
Project proposal No. 01/14
The application potential of current synthetic and special-purpose fibre pulps in regard of product optimisation and development
In addition to classical paper fibres, there is also a constantly expanding range of synthetic
special-purpose pulps that can significantly improve the performance of paper as a material.
The studies are intended to focus on bonding fibres, reinforcement fibres, fibrids, and fibres
based on biopolymers and functionalised fibre types, all of which are to be evaluated with
respect to their morphology, applicability in wet processing and their property spectra. Based
on the results, recommendations can then be made for product development and system
optimisation.
Background situation / Project motivation
In the search for new products with high value added, the paper industry has been focusing
to an ever greater extent on the fringes of the textile sector as well as the film and foil industries in which it is of the utmost important to selectively adjust the specific properties of the
products. The material paper constitutes a flexible material base for supplementary products
in the areas of light-weight construction, functional packaging and fibre composites. Synthetic organic fibres are a promising tool for expanding the potential properties of technical specialty paper in respect of strength, convertibility and resistance to chemical attack.
Objectives
The objective is a practice-oriented property mapping of synthetic organic fibres as far
as their impact and processability in wet processing are concerned. The focus will be
placed on those fibres that, until now, have typically not been used or only rarely used
in the papermaking process.
Contents / Solutions / Programmes
Suitable fibres will be proposed, selected and, if need be, provided by the project partners. In
addition to the manufacturer's details, the fibres will undergo supplementary examination
regarding morphology and suspensibility, and initial sheet formation trials will be conducted
using the Rapid Köthen sheet former. Based on these preliminary trials, a decision will then
be taken as to which types of fibre are to be used on the pilot paper machine. The pilot plant
has both a Fourdrinier section and an inclined wire section available. A variety of formulations and target directions are conceivable, depending on the types of fibre. The results are
intended to provide recommendations for the use of synthetic fibres for a variety of different
approaches in product optimisation and product development.

Project proposal no. 02/14
Vegetal fibre substitutes
Background / Motivation
Rising costs for traditional wood-based pulps as well as a strong market interest in ecological products suggest looking for alternative, “green” feedstock for paper manufacture. Materials like straw, grass, pomace or husks are possible options. The partial substitution of
standard feedstock opens up opportunities for cost savings, modified product properties and
environmental benefits.
Objective
The project aims at preparing selected fibre substitutes and testing their suitability. Product
samples shall be produced. The feasibility for defined paper grades shall be demonstrated.
Content / Approach / Programme
Five to eight promising fibre substitutes, preferably agro and agrifood residues and byproducts, will be agreed upon based on input from the project partners and PTS knowledge.
Available mechanical or chemical non-wood pulps could be among these, too. Suitable pretreatment processes will be identified and applied (as far as available at PTS), e. g. dry
grinding, pre-washing or pre-extraction. The materials will be suspended and refined to two
or three freeness levels. The pulps obtained will be characterised.
One or two reference paper recipes will be defined (secondary/virgin fibre based). Lab
sheets will be formed to assess the influence of fibre substitute additions on common optical,
strength and structural properties.
Successful parameter settings will be scaled up to the pilot paper machine. The paper samples produced will be provided.
Based on the results, the partners can decide on further development work. Additional criteria to be evaluated will be highlighted.

Project proposal no. 03/14
Paper-technological production of natural fibre composites for moulded parts
Background / Motivation
Moulded parts can be obtained from papermaking fibres by deep drawing. The resulting
products are mainly used as dishes or containers in the packaging sector, their main advantage over plastic packages being recyclability. Paper-technological methods can also be
used to obtain more durable products similar to applications of natural fibre-thermosetting
plastic composites. Newly developed special fibres based on PLA/PHB/starch, for example,
enable sustainable paper products that surpass conventional PE/PP fibre-based papers in
major converting properties like formability and heat-sealing behaviour, or can be used for
more durable applications in areas like vehicle interior fitting.
Objective
Aim of this project is to investigate the suitability of thermoplastic fibres obtained from renewable raw materials, among other, for improving the formability and further converting
properties of paper, and to prepare suitable sample materials.
Content / Approach / Programme
Suitable fibres will be chosen and/or provided by project partners. Functional fillers can be
investigated as well, to integrate further functions like fire protection or electromagnetic
shielding. The product groups to be produced in pilot paper machine trials will be selected on
the basis of pre-defined pulp formulations. Trials can be performed by means of both fourdrinier and inclined wires. Depending on the forming method used, different pulps and applications are conceivable. The product groups and pulps to be focused on will be selected by
screening.
The materials obtained will be tested by both standard methods and dynamic-mechanical
analysis (DMA) to determine their basic characteristics and thermo-mechanical forming
properties.

Project proposal no. 04/14
Using fillers, additives and fibres to improve the formability of paperboard
Background / Motivation
The deep drawing of paperboard materials to increasingly complex shapes is becoming ever
more important in paper converting. If at all, fillers have rarely been used in these segments
so far. Fillers interacting with fibres and additives can, however, specifically contribute to the
forming process if the anisotropy of fibres and sliding properties of individual plies as well as
the friction coefficients between plies are suitably adapted.
Objective
Relationships between filler properties and forming behaviour are to be identified, focusing
especially on the type, modification and usage point (surface or mass) of fillers in the papermaking process.
Content/ Approach / Programme
Suitable fillers will be selected and/or provided by project partners. Fillers will be screened in
machine trials to select suitable types for further investigations using the pilot paper machine. The latter will focus on different ply structures of the multiply board and, if desired, on
the spraying of fillers on intermediate plies.
