Research & Development - R & D in Nitin begins either at customer's feedback i.e. when the customers' demands a change in the material ordered or when an in house observation related to quality is suggested. In such cases trials are made to produce the required output. Once the trial is over processes are optimized to produce results as suggested by trial proceedings. In many cases the yarn is used to produce trial end product by R & D lab. If necessary, weaving, knitting or dyeing is also done to understand the end-users quality requirements. This helps check whether the produced yarn meets the requirements of the end user.
