01To Design & Develop Simulation Model for Phase Change Material based All-Weather-Jacket

Introduction PCM(s)
02
 Phase Change Materials or PCM(s) are those that can absorb, store and release large
amounts of energy, in the form of latent heat, over a narrowly defined phase change
range, during which the material changes state.
 In particular, the energy storage materials such as phase change materials (PCMs) that are
added into textile fibers are also an effective method to fabricate thermo-regulation
smart textiles.

Introduction PCM(s)
03
 More than 500 natural and synthetic PCM(s) are available, based upon:
1. Phase change temperature ranges
2. Heat storage capacities.

Working of PCM(s) in Textiles
 When a PCM based material is facing a rise in temperature due to external or internal
conditions, its solid phase encapsulations starts absorbing heat energy under constant
temperature and change to a liquid phase, thus providing a cooling effect to the user and
vice versa.
 PCM fabric referred as “Active
Smart Textile”, capable of sensing
and reacting to the conditions or
stimulus.

Problem Statement
05
 People living or working in the frosty or hot environment have shown the need for
clothes that can keep them warm in cold season and cool in warm season.
 Traditional clothes are unable to fulfill such requirements, “Smart Textiles” is the only way
to overcome such requirements as these (Smart-Textiles) are capable to sense and
response to the outdoor conditions.
 If PCMs are integrated into the textiles, the insulation capacity of the textiles can be
greatly improved, due to large thermal storage capacity and almost constant phase
change temperature of PCMs.
 People want to wear dress which is suitable and comfortable for all seasons .
 Many attempts have made to develop a jacket that can be worn regardless of any season
of the year as it works in different climate zones.

Aims & Objectives
06
 This research aims to design & develop such PCM(s) based jacket that regulate body
temperature, i-e no change in temperature of the encapsulated PCM(s).
 Based on comfort, geometrical, mechanical, and thermal characteristics, which give
insight into heat management through clothes to produce outdoor and protective clothes.

o Paraffin is the preferred kind of PCMs
for textile applications b/c melting
point of paraffin is very close to
temperature of the body.
o These are enclosed in a microcapsule
to prevent leakage of material during

Design & Material Selection
 Required properties of PCM(s) in Textiles
1. Melting point between 18 and 35 °C.
2. Large heat of fusion.
3. Small temperature d/f between melting and crystallization point.
4. Harmless to the environment.
5. Low toxicity & Non-flammable
6. Good stability for repeated phase change.
7. Large thermal conductivity.
8. Ease of availability & Low price
 Paraffin wax meets most of the mentioned properties, it is an excellent material for storing
heat, with a heat of fusion of 200–220 J g−1.

Design & Material Selection
 Besides, the PCMs with a phase change temperature range from 18 °C to 35 °C is the most
suitable for application in clothing.
 Selected materials is Paraffin wax (or petroleum wax), it is a soft colorless solid derived
from petroleum, coal or shale oil.

Applications
 In future smart textiles with PCM
will play an important role because
interactive smart textiles are
commonly used in healthcare,
performance sportswear and military.
 These fibers also have been used for
producing lightweight all-season
blankets.

Conclusion
 In this study, the fundamental principles and design methods related to the materials like,
Nylon fabric 6,6, Paraffin wax inside polyethylene tubes and bottom layer of Nylon 6,6
were examined, the results identified by carrying out simulation approach are almost equal
to the actual measurements that are taken through the prototype by using the temperature
sensors.
 As per the obtained test results of the prototype and simulation results, selected fabrics are
suitable for design of an all-weather jacket.
 In case of breathable nylon fabric, the purpose of face fabric is to protect and look stylish.
 The most important aspect is that the simulation of the jacket portion (20cmx20cm) that is
carried out by giving the proper properties and specification to the different layer of the
jacket. The simulation results and actual results are almost same.

Conclusion
 The selected paraffin is suitable in all aspects. It can be concluded that, all the basic things
consumers need for a good outdoors jacket for all seasons, that’s not only light weight but
also comfort and very functional.

Recommendations
 The performance of existing model of the Phase change material-based jacket can still be
improved, especially in the aspect of change the material properties of the phase change
material by considering the following aspects.
a) Increasing the performance parameters of the phase change material like latent heat range.
