Method for preparing polyester heddle twine for jacquard loom

Abstract

The present invention relates to a production method of jacquard polyester heddle twine. Said invention utilizes selection of industrial polyester multifilament and uses it as new material for makingheddle twine on the lay-over arrangement of jacquard loom, and adopts the processes of improved cabling, sizing and infrared drying so as to obtain the invented product jacquard polyester heddle twine. As compared with existent jacquard polyester heddle twine its tensile breaking strength is raised by once, under the identical test condition its expand and contract amount of reduced by 20-95% andits cost also is reduced by 30%.

Description

Technical field: [0001] The invention belongs to the field of textiles, and relates to a method for manufacturing polyester harness of a jacquard loom. Background technique: [0002] With the gradual increase of the weaving width of the jacquard loom, higher requirements are put forward for the harness on the shedding device of the jacquard loom. It is an important issue that the mouth is clear, weaves smoothly and can effectively reduce the warp defects of the fabric. [0003] At present, the harness on the shedding device of the existing jacquard looms in China is basically to spin the purchased vinylon stretched and cut yarn through the spinning frame into a vinylon single yarn with 430-450 twists / m and a tex of 29.5, and then Three vinylon single yarns with 430-450 twist / m and 29.5 tex are initially combined and twisted by the twisting machine to produce 88.5-tex vinylon strands with 570-590 twist / m, and then three The 88.5-tex vinylon strands are recombined and twiste...

AI Technical Summary

Problems solved by technology

The product was sold to the weaving factory. Due to the large change in the stretching of the harness, it affected normal production. Especially in the season of yellow mildew in the south of the Yangtze River, the factory reflected extremely strongly. During this period of time, the stretching of the harness was particularly large, seriously Affect the shed definition of the loom, greatly reduce the weaving efficiency of the loom, easily cause fabric warp defects, and even break the harness, causing constant disputes between harness manufacturers and harness manufacturers

[0005] In addition, the price of domestic raw materials for the manufacture of vinylon wire for jacquard looms has reached more than 18,000 yuan / ton, resulting in the continuous increase in the production cost of vinylon wire for jacquard looms
