Embodiment 1
[0022] Manufacture various functional polyester filaments first:
[0023] 100D / 36F three-lobed special-shaped bright and flame-retardant FDY was prepared on FDY spinning equipment with flame-retardant modified polyester chips;
[0024] 50D / 24F cross cationic FDY was prepared on FDY spinning equipment with cationic modified polyester chips;
[0025] 50D / 36F five-lobed special-shaped bright and anti-ultraviolet FDY was prepared on FDY spinning equipment with anti-ultraviolet modified polyester chips.
[0026] In this example, the manufacture of multi-different and multi-functional polyester composite slub yarn:
[0027] See figure 1 , below the zero roller of the stretching false twist texturing machine, install the pull-down yarn guide 2, which forms an off-angle α with the normal travel path of the filament to be 12°, and the vertical distance h to the pull-down point is 10cm. Open wire guide strut 4 overhanging distance is 15cm.

Embodiment 2
[0033] Manufacture various functional polyester filaments first:
[0034] 50D / 36F five-lobed special-shaped bright and anti-ultraviolet FDY was prepared on FDY spinning equipment with modified polyester chips;
[0035] 75D / 24F cross-shaped cationic FDY was prepared on FDY spinning equipment with cationic modified polyester chips;
[0036] 75D / 24F zigzag special-shaped bright antistatic FDY was prepared on FDY spinning equipment with UV-resistant modified polyester chips.
example 1
[0038] Single polyester filament 75D / 24F cross-shaped cationic FDY is fed from the zero roller of the air transformer as the raw material for the slub cortex, with an overfeed rate of 58.6%; Light antistatic FDY parallel ply is fed from one roller as raw material for slub core yarn. The vehicle speed is 200m / min. The setting temperature is 150°C, and the air variable mixed fiber composite method is adopted. A wool-like multi-differential multi-functional polyester composite slub yarn capable of moisture absorption and perspiration, anti-ultraviolet, dust-proof and anti-static, capable of over-dyeing with cationic dyes and different dyeing is obtained. The length of bamboo joints is 2 cm, and the density of bamboo joints is 8 pieces / m.

Abstract
The invention relates to a multi-hetero multifunctional terylene composite slubby yarn and the manufacturing method, which aims to solve the technical problems that the raw material has a narrow rangeof application, the slub is not firm or smooth and the product has a poor touch of unevenness and ventilation property. The core yarn of the slubby yarn consists of a plurality of combined modified terylene continuous yarns, and the slub cortex is formed by wrapping and winding a single modified terylene continuous yarn repeatedly. The manufacturing method includes the following steps: firstly, the core yarn is pulled down by a pull-down yarn guide (2) to an ante-case yarn guide (3) from a pull-down site (5); secondly, the single continuous yarn is fed in from another system, which has an overfeed rate of 40 to 70 percent compared with the feeding volume of the previous system; and thirdly, a separate opening is formed in front of confluence of the two blended fibers through an opening yarn guide (1) and the single continuous yarn with the overfeed is wrapped and wound on the surface of the core yarn repeatedly to form a discontinuous segmental sheath-core slub structure.
Description
technical field [0001] The invention relates to the field of textile fibers, in particular to a multi-different and multi-functional polyester composite slub yarn and a production method thereof. Background technique [0002] Polyester is a kind of chemical fiber clothing fabric raw material that is widely used in daily life. The biggest advantage of its fabric is that it has good wrinkle resistance and shape retention, and is suitable for outerwear. Generally, polyester fabrics have high strength and elastic recovery capabilities. It's strong, durable, wrinkle-resistant and easy-care. Good heat resistance, good light resistance, and good resistance to various chemicals. Acids and alkalis have little damage to it, and it is easy to dry after washing, and its wet strength hardly decreases, does not deform, has good washability and wearability, and its light resistance is better than natural fiber fabrics. Especially behind glass the light fastness is very good, almost on ...
