DTY DTY Ditan DTY Ditan polyester yarn polyester DTY

Polyester filament polyester yarn DTY DTY wire network FDY DTY POY- Hangzhou Rongsheng Chemical Fiber polyester filament yarn FDY DTY POY DTY network 1. spun polyester filament yarn: undrawn yarn (conventional spinning) (UDY), half pre-oriented yarn (spinning speed) (MOY), pre-oriented yarn (high speed spinning) (POY), high oriented yarn (ultra-high speed spinning) (HOY) 2. Tensile wire: drawn yarn (pull low stretch silk) (DY), fully drawn yarn (spinning stretching one-step) (FDY), taking all silk (spinning one-step) (FOY) 3. textured yarn: conventional textured yarn (TY), tensile deformation yarn (DTY), air-textured yarn (ATY). Classification criteria: §1, insurance organizations: to ensure that the solution sparse downstream weaving process, and satisfy the requirements of downstream weaving, continuous filament, which is a basic requirement. If you can not weaving, then regarded silk waste, substandard wire, it is necessary to re-inverted cones or mutilation. Due to lower equipment constantly updated to improve efficiency, this requirement will be higher and higher. §2, Paul color: Dyed must be consistent, that is, hands of customers, that must suck the color is consistent, so that after weaving cloth items can be uniformly dyed. And our general product determines the order of 4 (gray card), special products for the 4.5, and the client because kinds of cloth, or silk processing different specifications, or different uses, color grade on the sentence we must have separated. But the first-class production and processing silk mill no longer has sentenced four colors. Are 4.5 standard so that products can multi-use, but also to avoid staining in sales due to the number of levels causing distress. This is just one part of the sentence, even if the color is also due to 4.5 after processing products have different characteristics can not not classified sales. AAA grade knitting purpose of absorbing cloth color requirements are particularly sensitive species, use and set level. §3, as long as: a consistent length of each yarn, mainly in the warp direction due to warping while there are hundreds of thousands of pieces of yarn while warping the disc head. If the length is different, the warping rate of poor, make yarn short code, resulting in loss of customers, and therefore warp requirements shall be fixed length and fixed weight, the maximum error length is preferably less than 0.5%. §4, fixed weight: AA grade wire, each weighing can be controlled at ± 150g, which is yarn fineness, length, oil is not absolutely consistent rate, the greater the deviation, expressed our products still have shortcomings or small blemishes. Emori Architecture PTA: At present, the Group has in Ningbo and Dalian has built a large-scale production base PTA, PTA production bases in Hainan under construction. Grand Plaza in Dalian Petrochemical Co., Ltd. was established in April 2006, in 2009 was recognized as a national high-tech enterprises. Grand Plaza's main products for purified terephthalic acid, referred to as PTA. The current production capacity of 225 tons / year. Located in Ningbo, Zhejiang Yisheng Petrochemical Co., Ltd. was established in 2003, is focused on supporting Lieruningbo City billion project, is a professional production of purified terephthalic acid (PTA) of the modern large-scale petrochemical enterprises, currently has production capacity of 3.4 million PTA tons / year. Polyester: Currently, the Group has built production capacity of one million tons of polyester in Hangzhou Xiaoshan headquarters. Emori petrochemical and chemical fiber Wing Cheung polymerization project uses DuPont technology is the introduction, by the Chemtex design, polyester plant construction, the reaction over a period of two esterification and polycondensation were completed, with a short process, the production capacity big, raw materials and low utility consumption, is the world's most technologically advanced equipment is currently one of the largest polyester. Shengyuan chemical fiber polyester project uses a direct esterification China Textile Industrial Engineering Institute independent research and development, continuous polycondensation of polyester four reactor process technology, ensuring the stability of product quality and uniformity of the premise of providing operational flexibility, its raw material consumption and product quality have reached the international advanced level, the overall energy consumption in the international advanced level. Spinning: Currently, the Group since the company Emori Sinopec Corp. and its subsidiaries have completed FDY and POY 57 万吨 annual capacity. Emori petrochemical spinning core equipment production lines are from Japan, Germany, the introduction, most of which is polymerized directly spinning, stable product quality, complete specifications. Sheng Yuan project is under construction, the first in China to introduce the German AUTEFA company's high-end industrial automation equipment, with winding automatic doff - Intermediate dimensional storage - automatic packaging, such as automatic integration function, representing the most advanced level, reducing labor intensity and labor costs, as well as producing high-quality products to provide a guarantee. Texturing: Currently, the group and its subsidiaries from the company Emori petrochemical company has built an annual capacity of DTY 25 万吨. Canadian bomb equipment are from Japan, Germany, the introduction, including Germany Barmag texturing, including the world-class equipment. Emori advantage?
