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 liquid 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 shaping. The calendering temperature is 190°C, the speed is 5m / min, the singeing speed is 15m / min, an...

Abstract

A segment-color slub fabric, which is prepared by spinning segment-color slub yarn. The preparation steps of the segment-color slub fabric include: preparing segment-color slub yarn, yarn spinning, weaving, and finishing. Several air-permeable hollows are provided on the cylinder wall of the spinning cooling shell for preparing segmented colorful slub yarns, and the side blowing cooling air flows through the several air-permeable hollows and enters the spinning cooling shell through the spinning cooling shell. The interior of the shell cools the as-spun silk; the several air-permeable hollow parts are arranged in a helical shape around the cylindrical spinning cooling cover, and the widths of the beginning ends of the several air-permeable hollow parts are larger than the width of the tail ends. And the width from the beginning of the air-permeable hollow part to the width of the tail end changes linearly along the direction of the helix of the air-permeable hollow part; the primary filaments after this cooling become semi-solidified; The as-spun silk at other positions cannot be fully cooled by the cooling air flow of the side blowing, and is still in a viscoelastic 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...
