Problems solved by technology

However, the three-roller and four-roller methods hold different lengths for the roving, so it is difficult to achieve synchronous drafting of the roving and drafting at the same point, resulting in a slub-like change in the axial direction of the segmented colored yarn, which restricts the use of the segmented colored yarn in various types. Wide range of applications in fabrics
[0008] Due to the technical defects of the printing and dyeing segment color yarn, it cannot well meet the yarn requirements of occasional color fabrics. Therefore, there is an urgent need to develop a new segment color yarn and a preparation method for occasional segment color fabrics. Make it possible to obtain good occasional color effects, and then weave segment color fabrics that meet the requirements

Embodiment 1

[0045] A segmented color slub fabric, which is prepared by spinning segmental color slub yarn, the preparation steps of the segmental color slub fabric include: preparing segmental color slub yarn, yarn spinning, weaving, finishing; the segmental color slub yarn The preparation method comprises the following steps:

[0046] (1) Drying of polyester slices, hot air drying of polyester slices and color masterbatch respectively; the drying process can also include a pre-crystallization process;

[0047] (2) The polymer slices and masterbatches are mixed in proportion and sent to the screw extruder. The screw extruder is divided into six zones. The first two zones are the feeding section, the middle two zones are the compression section, and the last two zones are the metering section. Mixing section: concave-convex anti-adhesion mechanisms are provided on the surface in contact with the polymer melt inside the screw extruder, and the concave-convex anti-adhesion structures are eve...

Embodiment 2

[0062] Adopt semi-dull polyester chip to prepare yarn and fabric as spinning raw material, its concrete implementation process is identical with embodiment 1, concrete parameter is:

[0063] The temperature during spinning is 250 degrees Celsius, the initial pressure during spinning is 16mpa, and the density of spinneret holes is 3 holes / cm 2 , the diameter of the spinneret hole is 0.35mm, the wind speed of side blowing is 0.6m / s, and the range of wind speed fluctuation is ±0.6m / s.

[0064] According to actual needs, the specification of the single-ply yarn is 20s, and the specification of the double-ply yarn is 20 / 2s.

[0065] The finishing solution includes 10wt% of modified nitrile emulsion, 10wt% of phosphates, 6wt% of nano-silver, and the balance is water.

[0066] In order to improve the appearance of the fabric, calendering and singeing are also included after drying and setting. The calendering temperature is 190°C, the speed is 5m / min, the singeing speed is 15m / min,...

Abstract

Provided is a section-color bamboo joint filament fabric. The fabric is made by adopting section-color bamboo joint filaments. A making method of the section-color bamboo joint filament fabric comprises the making steps of section-color bamboo joint filament preparation, yarn spinning, weaving and after finishing. A cylindrical wall of a spinning and cooling cover housing for making section-colorbamboo joint filaments is provided with a plurality of breathable hollow-out portions, laterally-blown cooling airflow penetrates through the spinning and cooling cover housing through the multiple breathable hollow-out portions to enter the spinning and cooling cover housing and cool spun filaments; the multiple breathable hollow-out portions surround the cylindrical spinning and cooling cover housing and are arranged in spiral line shapes, the starting ends of the breathable hollow-out portions are greater than their tail ends in width, and linear change is formed from the widths of the starting ends of the breathable hollow-out portions to the widths of the tail ends of breathable hollow-out portions in the directions of the spiral lines of the breathable hollow-out portions; the cooledspun filaments are changed to a semi-solidified state. The spun filaments located in other positions in the spinning and cooling cover housing are not fully cooled by the laterally-blown cooling airflow and are still in a sticky-elastic state.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a segment-colored slub silk fabric. Background technique [0002] Colored fabrics have always been the focus of research in the research and development of textile fabrics, and the artistry of colored fabrics is also one of the main indicators for considering their market economic value. In recent years, occasional color fabrics have become more and more popular in the market. The so-called occasional color refers to the phenomenon of open color that causes the color to grow freely due to the intervention of accidental factors during the creation process, showing image dissipation, uneven distribution, and overlapping layers. Occasional color fabrics are endowed with extremely high additional economic value due to their unique artistic value, and are sought after by many fabric manufacturers. [0003] The general means of developing occasional color fabrics include dyeing and w...
