Description
Technical Field
The utility model relates to the field of spinning equipment, in particular to a hollow extinction velvet-like fiber spinneret plate.
Background
The spinneret plate is a commonly used product in the textile chemical fiber industry, and comprises a feeding surface and a discharging surface, wherein a feeding hole is formed in the feeding surface, and a discharging hole is formed in the discharging surface. The spinneret plate is used for converting a viscous polymer melt or solution into a thin stream with a specific cross section through micropores, solidifying the thin stream through a solidifying medium such as air or a solidifying bath to form filaments, namely, entering from a feeding hole and exiting from a discharging hole. The discharge hole on the common spinneret plate is circular, and the non-circular spinneret plate is called a special-shaped spinneret plate. The profiled hollow fiber is a chemical fiber with profiled hollow section shape and special function, which is formed by extruding spinning melt through a spinneret orifice with profiled hollow shape, bonding the end parts to form a hollow cavity, and refining and solidifying. Matting fibers, also known as matt fibers, refer to chemical fibers with matt surfaces, and are usually prepared by adding a matting agent (titanium dioxide) to a spinning solution or melt prior to spinning, and spinning to form the fiber, so that the fiber scatters light to eliminate gloss to reduce transparency and increase whiteness.
Profiled fibers having different cross-sectional shapes can be spun using a composite spinneret having spinneret orifices of different shapes and sizes. The cross-sectional shape of the fibers affects the performance of the yarn and the fabric, and the improvement effect of the fibers with different cross-sectional shapes on the yarn and the fabric is different. The Chinese patent with the publication number of CN 202755113U discloses a five-leaf hollow spinneret plate, which consists of a spinneret plate body and spinneret orifices, wherein each spinneret orifice consists of 12-144 spinneret orifices with the same structure, each spinneret orifice consists of five units, each unit is provided with a long slit and two short slits with the same length, a communicated five-leaf shape is formed, the two short slits with the same length of each unit are all arranged inwards, the two adjacent short slits are spaced and are not communicated with each other, a pentagonal hollow is formed inside the hollow spinneret plate, the good spinnability is maintained, the five-leaf hollow structure inside the fiber is provided with capillary pipelines on the surface of the fiber, the cross section of the fiber is special-shaped, and the five-leaf hollow spinneret plate has the characteristics of moisture absorption, sweat release, fluffiness, warmth retention and the like.
However, the current fiber materials are various, and the fiber production process is different, for example, the method disclosed in application publication No. CN1278026A needs to be a dry method of stretching at 50-100 ℃ and then heat-treating at 120-180 ℃ or a dry method of stretching in boiling water at 85-100 ℃, then drying at 95-130 ℃ and then heat-treating at 100-140 ℃. Although the above-described solutions improve the material of the fibers and improve the heat shrinkage, the heat shrinkage during production is still unavoidable. The fiber produced using the disclosed five-bladed hollow spinneret does not actually achieve the desired effect due to the heat shrinkage, because: in the fiber stretching process, the material ejected from the long slit is shortened due to heat shrinkage, and the heat shrinkage degree of the material ejected from one end outside the long slit is larger than that of the material ejected from one end inside the long slit, so that the length of the fluff of the finally formed fiber is shortened, the cross section is in a shape with a narrow outside and a wide inside, and the fluffy warmth retention property and the moisture absorption and sweat release property of the fiber are seriously affected.
