Preparation method and device of composite textured yarn

Abstract

The invention discloses a processing method and a device of composite textured yarn, the device comprises a rack, a heating deformation mechanism arranged on the rack, a yarn guide mechanism arranged on one side of the rack, a yarn coiling mechanism arranged on the other side of the rack, wherein the heating deformation mechanism comprises a driving wheel and a matched yarn pressing wheel, the driving wheel and the yarn pressing wheel are arranged at the left and the right, the yarn pressing wheel is higher than the driving wheel, the connecting line of shaft centers forms an included angle of 20-40 degrees with the horizontal line, and heating devices are arranged on two sides of the driving wheel; the wire guide mechanism comprises a detwisting bobbin creel, a cocoon cooking pot and a tensioner; the yarn coiling mechanism comprises a yarn holding tool, a winding motor connected with the yarn holding tool and a speed regulator; and a special-shaped yarn guide wheel, a yarn storage device and a yarn guide device are sequentially arranged between the heating deformation mechanism and the yarn coiling mechanism. The processing method and the device can carry out composite deformation processing on the yarn with different components, completely realize the winding without tension, realize the continuous production of the composite textured yarn and keep the deformation effect.

Description

technical field [0001] The invention relates to a preparation method and device for yarn, in particular to a preparation method and device for composite textured yarn. Background technique [0002] Deformation processing is a secondary processing method commonly used in the textile industry. Its purpose is to change the appearance geometry of the yarn, so that while obtaining the curl deformation effect, the stretching elasticity and fluffy fullness of the yarn are greatly improved. . Textured yarn has played an important role in enriching the types of textiles, improving fabric feel, increasing fabric elasticity, fullness and hairy feel, the most typical product is synthetic fiber elastic yarn, such as: polyester low elastic yarn, nylon high elastic Silk etc. [0003] For synthetic fiber filaments, physical and mechanical deformation processing is generally carried out by utilizing its thermoplasticity. The existing deformation processing methods mainly include false twis...

AI Technical Summary

Problems solved by technology

[0006] In summary, although deformation processing is an indispensable technical means in the secondary processing of yarns, the current deformation processing methods of real silk and synthetic filaments are mainly based on twisting-setting-untwisting and false twisting. Mainly deformed; in terms of product category, synthetic fiber textured filament yarn is mainly composed of a single component, and real silk composite textured yarn generally has only two components, such as: silk / nylon FDY silk, and others are only a single silk texture or Real silk and synthetic fiber composite, so far there is no report on the processing method and processing device of real silk / synthetic composite textured silk with controllable components and shapes
