Knitting looping and crocheting involve interlacing loops of yarn which are formed either on a knitting needle needle or on a crochet hook together in a line. The processes are different in that knitting has several active loops at one time on the knitting needle waiting to interlock with another loop while Looping and crocheting never have more than one active loop on the needle. Knitting can be performed by machine but crochet can only be performed by hand.
Since the 1990s with advances in technologies such as permanent press process finishing agents have been used to strengthen fabrics and make them wrinkle free.22 More recently nanomaterials research has led to additional advancements with companies such as Nano-Tex and NanoHorizons developing permanent treatments based on metallic nanoparticles for making textiles more resistant to things such as water stains wrinkles and pathogens such as bacteria and fungi.
Textiles receive a range of treatments before they reach the end-user. From formaldehyde finishes (to improve crease-resistance) to biocidic finishes and from flame retardants to dyeing of many types of fabric the possibilities are almost endless. However many of these finishes may also have detrimental effects on the end user. A number of disperse acid and reactive dyes (for example) have been shown to be allergenic to sensitive individuals.24 Further to this specific dyes within this group have also been shown to induce purpuric contact dermatitis.
