Description
Technical field
The present invention relates to a kind of functional textile, be specifically related to a kind of blended color spinning yarn and production method thereof of Novel polyester imitation cotton fiber.
Background technology
China's textile chemical fiber industry is in the new stage of transition and upgrade innovation and development, and cotton gap problem has become a difficult problem for restriction industry development.For alleviating the deficiency of the natural fabrics such as cotton, country will research and develop a new generation's high emulation differentialand functional fiber further, advance weaving novel high added value, super emulating fabric fabric series of products, as the most important strategic tasks that the weaving of " 12 " period, chemical fibre advance jointly.
The super imitative cotton fiber of existing market is all true qualities yarn varieties, and due to dyeing and spinnability limitation, also effectively not applying in colour-spun yarns field, is a blank.Porel fiber is the modified polyester fiber that fibre technology Development Co., Ltd of Nanjing Donghua University is made by the method for chemical modification, is the Novel polyester imitation cotton fiber of capillary lumen hollow structure.
This fiber belongs to Cationic Dyeable Pet, available cation dyes dye, but when spinning for look, exist dye level low and spin cotton and weave cloth after washing time to be unstained the defect of the easy variable color by staiing of Porel fiber, thus spin in production can not dye to Porel fiber by cation dyes at look.Porel fiber also can be selected to dye by DISPERSE DYES simultaneously, but Porel fiber has the alveolate texture of hollow, after adopting disperse dyeing, the loose colour dyestuff of hollow part is difficult to clean up, and this structure is very easy to again absorption loose colour dyestuff, making the colour-spun yarns made be very easy to when washing stain variable color, thus can not dye with conventional disperse dyestuff.In addition, in stock-dye process, the original finish of fiber has been fully processed totally, again through High Temperature High Pressure, the original performance of fiber and feel all there occurs great changes: look fine powerful obviously decline, and contraction in various degree appears in fibre length, and ratio resistance presents the increase of geometry multiple, partially soft, the partially puckery or cunning excessively of feel, makes the fiber spinnability after dyeing very poor.
