This volume explains knitting technology in an easily-comprehensible and user-friendly manner. The manufacturing of a cost-effective quality product requires careful planning and thorough knowledge of the product as well as production technology. To achieve the desired functional properties in fabric, the relationship between the raw materials, process and finished product is very important. Knitting has been and remains an important textile technique due to the properties of knitted fabric such as elasticity, stretchability, and comfort. Despite the prominence of knitwear, there has been limited data regarding mechanics of weft knitted fabric and effect of structures on physical, mechanical and comfort properties. This book is an attempt to fill that gap. The book provides knowledge about fabric manufacturing techniques, weft knitting structure, and methods of evaluating knitted fabrics and their applications in technical textiles. It also discusses different types of yarn and their manufacturing processes. Testing and quality control in industrial practice as well as management of a fabric dyeing house are also covered.

A synthetic thermosetting polymer, epoxy consists of two components the resin and the curing agent. The resin provides a sufficient number of highly reactive terminal epoxide groups, and the curing agent is responsible for bonding with the resin at these epoxide groups to form a rigid cross-linked network. Epoxy resins are versatile due to their excellent mechanical, thermal, corrosion-resistant, chemical resistant and adhesive properties. As a result, epoxy composites are widely used in structural applications. Depending on the starting materials and the synthesis method, various epoxy resin types can be synthesized. Epoxy can be categorized into two families, glycidyl and non-glycidyl epoxies, which are further classified into various types. A variety of factors drives the choice of resin. Some of them are the viscosity of uncured resin, epoxy equivalent weight, curing behavior, cross-linking density, glass transition temperature (Tg), and service performance. The epoxy equivalent weight (EEW) is the ratio of the molecular weight of the epoxy monomer to the number of epoxide groups present. It is represented in terms of g/equivalent. EEW of a resin is used to calculate the amount of hardener required to achieve optimal curing in that resin. A stoichiometric or near-stoichiometric quantity of hardener should be added to the epoxy resin to achieve a good quality cured epoxy.Uncured epoxy resins are inadequate for practical applications and therefore need to be cured using a curing agent. A suitable hardening agent can be chosen depending on the type of epoxy being used and the desired end application of the epoxy composite.
