This chapter reviews relevant findings regarding the activities and contributions of chitosan in different textile processing following the varieties of process, mechanism, and applications. Chitosan is a better candidate in both aspects of biodegradability and efficiency instead of synthetic polymers. The technical and scientific discussions behind the role of chitosan in all the processes   This book forms the proceedings of a workshop held in Hiroshima in June and derive from the work of a Technical Committee of the Japan Concrete Institute.

Textile fabrics have been improved to assist in thermal and moisture regulation to and from human body through engineering of fibers, yarns and fabric construction, and In the first part, a new model for the exergetic analysis of the convective drying of textiles at stenters was presented and the variations of exergetic parameters for each chamber of the stenter Thermophysical parameter estimation of a wool bobbin during convective drying process Article (PDF Available) in Inverse Problems in Science and Engineering 18(2) March with Reads XRD analysis showed that drying had little effect on fiber crystallinity, indicating that drying only leads to changes in the physical properties of wool fabrics instead of changes in the chemical The challenges for convective drying of fruit lead to overcoming the dependence on empirical models for drying parameters determination, the lack of shrinkage inclusion and 3D modelling by means of advanced procedures such as multi-scale and conjugated :// Shock pre-drying is a combination of vacuum extraction and convective drying methods that provides rapid drying due to the synergy between heat energy and mechanical ://   the drying process.

One of the most important drying parameters is the drying rate (Figure 4) which represents the rate of evaporated water from one square meter of drying product. At the beginning of the process the drying rate increases from g/s m2 to g/s m2 and then has a very small decreasing slope.

At the end of the process the   drying of textiles. In chapters 3 and 4, heat conduction and heat radiation in drying process of textiles are presented, respectively.

A dyeing process is the interaction between a dye and a fibre, as well as the movement of dye into the internal part of the fibre. Generally, a dyeing process involves adsorption (transfer of dyes from the aqueous solution onto the fibre surface) and diffusion (dyes diffused into the fibre).

A book which lies between these two extremes would be of value to those with an intermediate understanding of the physical sciences.

Thus this book dis­ cusses textile fibers, dyes, finishes, and processes using this intermediate ap­ proach, presenting in a concise manner the underlying principles of textile chem­ istry, physics, and ~lu/    The Drying Curve For each and every product, there is a representative curve that describes the drying characteristics for that product at specific temperature, velocity and pressure conditions.

Dyeing is a very complicated process with many different phenomena occurring simultaneously. It covers different areas of science including chemistry, physics, mechanics, physical chemistry, fluid mechanics, thermodynamics and others. 1 Devising the most efficient dyeing process typically involves the following concerns: machinery design, pre-selection of dyes of compatible   weight fabrics for outerwear are multi-layered (coated or laminated) and their properties differ from light weight fabrics.

Parameters of these fabrics due to structural difference are highlighted here with specific focus on functional apparel.

The Effects of Different Fabric Types and Seam Designs on the Seams [sic] Efficiency Abstract Fabricated textile products require joining fabric together by some means.

The influence of various factors on the protective and comfort performance of thermal protective clothing is critically reviewed. It has been identified that factors related to the properties and features of fiber (eg, linear density, cross section), yarn (eg, types, twist), fabric (eg, surface properties, structural properties), and garment (eg, fit, design, closures) mainly affect the Wet processing of textile materials consumes a large amount of electricity, fuel, and water.

Therefore, greenhouse gas emissions and contaminated effluent are environmental problem. The most of the governments in the world warn all the industrial sectors containing textile manufacturing to be careful about environmental pollution.
