Problems solved by technology

For example, fibers with triangular, pentagonal, and trilobal cross-sections all have the characteristics of good hand feeling and silk-like flashing effect, but their water absorption and quick drying, moisture permeability and fluffiness are poor, which limits their applications; and cross-shaped, H Although special-shaped fibers with C-shaped and C-shaped cross-sections have the characteristics of light weight, water and sweat absorption, etc., their fiber luster is not good, and colorful fibers cannot be produced, which affects the wearing performance and style effect of the fabric.
From this point of view, the special-shaped fiber produced by the prior art cannot have the advantages of good luster, water and sweat absorption, light weight and warmth, etc. Therefore, it is urgent to develop a new special-shaped fiber with multifunctional properties to enrich the present There are products to meet people's needs for textiles with multiple functions

Embodiment 1

[0019] This embodiment adopts the one-step method of melt spinning and stretching, and the nylon 6 chips are melted by the screw, and the melt is input into the metering pump and the spinning assembly, and the melt is extruded from the spinneret with 40 spinneret holes to form a melt Fine flow, cooling and solidification in the cooling zone of the surrounding air blowing, clustering and oiling, drafting and heat setting, winding and forming, and a double wavy linear nylon 6 filament is obtained.

[0020] See attached figure 1 , which is a schematic diagram of the cross-sectional shape of a double-wave linear spinneret hole provided in this embodiment; the hole shape of the spinneret hole is a double-wave linear flat shape, and along the length direction of the spinneret hole, both sides are symmetrical waves The wavy line is composed of 3 identical arc-shaped curves, and they are connected to each other; the height of the arc-shaped curve is 0.045mm; the width of the narrow pa...

Embodiment 2

[0025] In this embodiment, after being melted by the screw, the melt is extruded from the spinneret with 40 spinneret holes to form a thin stream of melt, and the spinneret holes are arranged in a centripetal distribution mode; it is cooled and solidified in the cooling zone of the surrounding air blowing. , cluster oiling, drafting and heat setting, to winding forming, and a double-wave linear nylon 6 filament is obtained.

[0026] See attached Figure 4 , which is a schematic diagram of the cross-sectional shape of the double-wavy spinneret hole provided in this embodiment; the spinneret hole is a double-wavy linear flat shape, and along the length direction of the spinneret hole, both sides are symmetrical wavy lines , the wavy line is composed of 4 identical arc-curve connections, and they are connected to each other; the height of the arc curve is 0.045mm; the length of the spinneret hole is 0.90mm, and the aspect ratio of the spinneret hole is 5:1;

Abstract

The invention relates to a double-wave-line-shaped nylon-6 filament and a preparation method thereof. In a melt extrusion process, a spinneret hole is flat double-wave-line-shaped, symmetrically distributed wave lines are arranged on the two sides of the spinneret hole in the length direction, each wave line comprises 3-5 same arc-shaped curved lines which are connected, the arc-shaped curved lines are communicated with each other, and the length-width ratio of the spinneret hole is (4-6) to 1; in a cooling forming process, a cross air blow cooling mode is adopted, the cross air blow speed is 0.4 m / s to 0.6 m / s, and the cross air blow temperature is 20+ / -2 DEG C; in an oiling bundling process, a nozzle and an oil plate are combined for applying oil. The prepared double-wave-line-shaped nylon-6 filament has multifunctional characteristics of large specific surface area, soft luster, good dyeing property, moisture absorption and conduction, moisture conservation and ventilation, capillary tube wicking effect and the like, and endows a fabric with the effect characteristics of large void ratio, softness, light weight, large coverage range, good moisture absorption and ventilation properties, good moisture conservation and conduction properties and the like.

Description

technical field [0001] The invention relates to a special-shaped filament with multifunctional properties and a preparation method thereof, in particular to a double-wave linear nylon 6 filament and a preparation method thereof, belonging to the technical field of differential chemical fibers. Background technique [0002] At present, most of the widely used chemical fibers in the fields of clothing and decoration have circular cross-sections, which have disadvantages such as poor surface gloss, waxy feeling, easy to dirty, easy to pilling, non-absorbent, and small coverage. It is difficult to satisfy people's pursuit of comfort, thus limiting the development of chemical fibers to a certain extent. The special-shaped fiber has a non-circular cross-sectional shape, a large specific surface area and some special physical properties, which can make the gloss, feel, bulkiness, hygroscopicity, anti-pilling, pilling, stain resistance, stiffness, and Elasticity has been improved t...
