Textile units in Tirupur have asked spinning mills to supply cotton immediately, alleging that the latter stopped supplies without any reasons. Raja M Shanmugham, president, Tirupur Exporters Association (TEA) said that the mills have stopped supplying cotton yarn and are not taking up the fresh orders. “They have not given any reasons, despite the fact that prices have gone up by about Rs 50 a kg the past six months,” said Shanmugham, who has written to all the Textile Mills Associations, SIMA, TASMA and ITF to advise their members to supply the yarn continuously to protect the Tirupur Knitwear Exports sector.
