The Heritage of the Textile Industry
No full textNa okładce : Thematic Study for TICCIH - The International Committee for the Conservation of the Industrial HeritageThe textile industry is a global phenomenon. It was the impetus for industrialisation, the growth of cities, the creation of company towns and world-wide trading routes in staple goods: silk, wool, linen, cotton, jute and artificial fibres. Facing global economic changes, textile mills have proved adaptable to new purposes. Many spearhead urban regeneration and secure the future identity of places. Which lessons do mill conversions give?
Which are the pioneers, the flagships, the giants, and the time capsules - machinery, and related skills? Which networks best demonstrate international interchange? Did associated company towns fail or prosper? Some are World Heritage Sites - is the balance correct? What attributes do these places share, what makes them different, and what is missing? This book condenses input by several researchers into the better understanding of textile mills worldwide
Fiber cross-section influence on the deposition of nanofibers on textile weaved structures
No full textRoughness is directly related to the increase of adhesion between surfaces. Different cross section on
fibres implies different longitudinal shape of fibres, altering the roughness of filaments. In this study, a
procedure to evaluate the nanofibers adhesion to the substrate has been designed. In order to test it,
different cross-section shapes are evaluated to demonstrate its influence on the nanofibers net adhesion.
Circular, tetralobal and trilobal fibres were tested. Focused on corroborating it, two yarns with different
filament fineness were also tested. Different weights are placed on an acetate film which is placed on
the nanofibers net. The pressure helps the nanofiber to move to the acetate. This procedure helps to
determine the influence of fibre cross-section or roughness, demonstrating the adhesion of nanofibers
net on the structures is enhanced with higher roughness

No full textPhotocatalytic desizing of pva-sized cotton fabric
No full textSizing is necessary for the weaving preparatory process involving coating warp yarns with a sizing agent
like PVA. The sizing agent improves the weavability during the manufacturing of the cotton fabric.
Before dyeing and printing the fabric, removal of the natural or added impurities is essential. Desizing
is the initial step in the pretreatment of the cotton fabric, where the sizing chemicals are removed.
However, desizing is a water and energy-intensive process. A green methodology is employed here for
desizing PVA-sized cotton fabric using UVC in the presence of potassium persulfate as a photocatalyst
to replace the hazardous chemicals used in the conventional approach. The eco-friendly technology used in this article saves time, water, and energy by 79%, 67%, and 84% of the conventional process with better efficacy of desizing
Determinates of Implementing IT Services
No full textThe quality of implementing IT services may be differentiated on the market.
Nowadays, we have broad access to technology and scientific literature
that support company strategies. What makes the difference is the KPI
of IT service implementation, including (1) Time to deliver, (2) Cost, (3)
Risk management, (4) Flexibility in implementation to react to global drivers
(e.g. epidemic) during delivery.
The purpose of this article is to answer questions regarding the components
of service delivery. A good understanding of each stage and any related risks
is crucial. Each phase has been described in detail with its associated challenges,
starting with analysing the customer’s request and how IT companies
can respond. The prepared analysis of the individual elements of the process
is the basis for preparing the order fulfillment document.
Once the customer and company have signed off, there will be more
information on transitioning to the delivery team. In the delivery part of this
document, we will dive into the implementation details. Descriptions of
available and practically used methodologies and standards are provided.
The summary will collect the results of the incorrectly addressed needs during
the project, such as a wrong tool or methods used to deliver it
Nonverbal Communication as an Element of Image-Building
No full textNonverbal communication plays a crucial role in the modern world. Gestures,
facial expressions, tone of voice, posture, touch, eye contact, clothing and
accessories are just some of the elements that can be used to communicate
nonverbally. This article aims to present issues related to nonverbal communication
in an image-building context. This work will discuss and present
aspects of non-verbal communication, such as facial expressions, kinesics,
eye contact, proxemics, external appearance, touch, chronemics, paralinguistics
and olfactics
Cut protective materials from the point of view of working environment
No full textCut resistance is defined as the ability of material to resist a blade, which may be determined by means
of a variety and evaluation methods, depending on the intended use of the material and the applied
cutting factor. Some of the earliest studies on cutting were conducted in the 1990s involving textile and
polymeric materials. The obtained results were characterized by exponential regression indicating that
blade movement (the length of the cutting path) decreases with increasing loading. Those results were
reflected in the first version of the international standards specifying cut resistance testing [1–2].
Cut resistance tests given in international standards are mostly used for proving that products meet
specific normative requirements, but they fail to account for the complexity of the physics of cutting
and fall short in terms of evaluating advanced materials arising with the fast-paced development of
materials technologies [3]. Moreover, the available literature does not contain many research on the cut
resistance properties of e.g. three-dimensional hybrid textile materials taking into account the real
conditions of use. As a result, it is need to develop more objective methods for evaluating cut resistance
properties, therefore preliminary assumptions for the new method has been described in this paper
Walking simulator for the electrostatic testing of floorcoverings
No full textThe electrostatic characterization was performed using a walking simulator to validate it for a fully
automated test procedure using different dwell times between moves and time of the test. An existing
standard ISO 6356 measures the voltage created by a human walking on a carpet under controlled
settings. To generate the electrostatic charge, a walking person executes the actual test process and
manually calculates the findings. The newly constructed walking simulator, on the other hand, does not
require a person to compute peaks and valleys for the created electrostatic charges, which improves
precision, consistency, and reproducibility while also removing human error. The electronic platform is
supplemented with an automated foot that walks on the floorcoverings for a fully automated exam. Three
different dwell times between the moves of the automated simulator have been examined to see its effect on the electrostatic charge generation waveform amplitude and peaks values. We conclude that the thickness of the waveform is directly related to the dwell time between the move. The peaks voltage and
the amplitude of the electrostatic waveform of the walking simulator are decreased with an increase in
dwell times. The amplitude of the Electrostatic wave increases with the increase in testing time at the
same frequency, pressure, and stepping height, which shows that the generation of electrostatic charges increases until a saturation point
