Processes and Machines for Knitwear Production

According to the German Industrial Standard DIN 60000, knits are fabrics, made of one or several threads or one or several thread systems by stitch formation. It should read The respective terminology can be found in (DIN 62050, 1990). For further explanations of knitwear production see Au (2011), Ray (2011), and Spencer (2001). 

Besides the classic fields of application of clothing (pullover, underwear, stockings, sportswear, bathing suit fashions) and home textiles (net curtains, bedspreads, awnings, tablecloths, covers for furniture), knitwear is also used for technical textiles, including for helmet structures, medical textiles, geotextiles for dike and road construction, filter materials, material for insulation, and nets.

In order to form the actual loop and to interconnect the loops, different types of needles are used, as shown in Fig. 5.2. 

For knitting, mostly latch needles are used, whereas in warp knitting, slide needles are predominant. The advantage of latch needles is their flexibility regarding thread material and that there is no additional component needed to close the needle as is the case for slide and spring needles. However, slide and spring needles are cheaper to manufacture.
