Top yarn quality from a range of blends

By Irene Muggler

Rieters customer Shangshui Xianghu Textile wants to find a way of efficiently using the cotton noils and cotton waste from the blowroom and the card and to thus profitably optimize their raw material blends. Using rotor spinning machine R 36 has provided the company with an incredibly positive experience.

Shangshui Xianghu Textile Co.， Ltd. is located in Zhoukou City， Shangshui County， in the province of Henan （China）. The company produces 12 million meters of greige fabric and 4 500 tons of cotton yarn per year； its most important products are Ne 16 and Ne 21 yarn.

The Challenge： To produce optimal yarn from cotton noils and cotton waste

The raw materials used are 70% comber noil and 30% cot-ton waste from blowroom and card. The management wanted to use these raw materials to produce high-quality yarn in an economically efficient manner. The aim was on the one hand to maximize profits and on the other hand to bring the yarn fully in line with the requirements of customers of Shangshui Xianghu.

The Solution： Rotor Spinning Machine R 36

Shangshui Xianghu has therefore invested in four semi-auto-mated rotor spinning machines R 36 with 460 rotors each. The machines are easy to operate and offer a direct way to achieve high yields of highquality yarn. The R 36 fulfills every requirement specified by Shangshui Xianghu：

·The two sides of the machine operate fully independently and offer high flexibility.

·The excellent spinning technology， the yarn clearer Q 10 and the perfectly wound bobbins ensure a high quality product for the subsequent finishing process.

·The R 36 offers outstanding energy efficiency. Further-more， the optional automatic piecing technology which Shangshui Xianghu has elected to use has significantly reduced the time taken to restart the machine after power failures.

The benefits for Shangshui Xianghu： outstanding efficiency and reduction of personnel costs

The diverse functions of the R 36 have far exceeded the cus-tomers expectations：

·The efficiency of the machines is up to 99 to 100%， the potential productivity capacity is 2 to 3% higher than with comparable machines.

·The advantages in terms of labor costs are obvious： Fewer than 100 ends down per 1 000 operating hours results in a saving of up to 1 operator per machine compared to the former situation， thus sustainably reducing labor costs at Shangshui Xianghu.

·The companys customers are very satisfied with the yarn quality delivered.

The customer was able to increase its profits and Shangshui Xianghu was convinced by the excellent performance of the R 36 and has invested in two further machines.
