Polymer Properties When considering a polymer for use in any application it is essential to understand the behaviour of the polymer with respect to variations in temperature. Unlike metals or…
Polymerisation
Polymers are produced from their constituent monomers through a process known as polymerisation. Polymers can be produced through either addition polymerisation or condensation polymerisation. In addition polymerisation the monomers physically…
Polymer Types
There are 3 principal classes of polymers – thermoplastics, thermosets, and elastomers. Differentiation between these classes is best defined by their behaviour under applied heat. · Thermoplastic polymers can be either…
Crystalline or Amorphous
A polymer therefore is a series of long chain molecules composed into a complex arrangement to make a solid. There are two possible arrangements of the molecular chains. They are…
Functional Groups
Different types of polymers are produced when the hydrogen atoms are substituted for other atoms or molecules, called functional groups. One of the most common engineering plastics is polyvinyl chloride,…
Introduction to Polymers
Engineering materials commonly known as plastics, rubbers, and adhesives are all correctly referred to as polymers. Over 15,000 different types of polymers are commercially available and are categorised into 20…
Colour mixing in digital jacquard textile design
The colour mixture theory of woven fabric has to be established based on the employment of the limited colours of warp and weft threads. Among primary colour theories, the digital…
Colour mode changes in digital jacquard textile design
In addition to colour mixture, the change of colour mode as part of the design process of the layered-combination design mode of digital jacquard is of considerable interest. Figure 5.3…
Structure and colour in digital jacquard fabrics
Naturally, the woven structure of jacquard fabric is the foundation for colour mixture theory since the colour mixing of jacquard fabric is based on a woven structure interlaced with warp…
Colour mixture theory for digital jacquard textiles
In the design of digital jacquard textiles, the nature and principle of colour mixture appropriate for the fabric cannot be neglected. Not only do these principles govern the colour expression…
