example 1

[0096] Figure 9 is a schematic plan view of the cylindrical outer surface of the heat forming roll in the unfolded state showing the first distribution of the heated and non-heated areas of the heat forming roll. Assuming that the heated forming roll is used as figure 1 The first heated roll shown is used to produce multicolored slub filaments with cycle lengths.

[0097] The diameter of the heating forming roller is Φ=220mm, and the circumference is L=691mm. The surface of the heating forming roller is plated with a heat-conducting ceramic coating with a thickness of 0.2mm by using an ion plating process. The thermally conductive coating on the surface of the heated forming roller is removed by ultra-fine sandblasting to form grooves, and multiple grooves form a non-heating area. Such as Figure 9 As shown, the width of the heating zone formed on the surface of the cylinder is respectively:

[0098] the s 1 =100mm, s 2 =150mm, s 3 =80mm, s 4 =65mm, then: S=s 1 +s 2...

[0113] Figure 10 is a schematic plan view of the cylindrical outer surface of the heat forming roll in the unfolded state showing the second distribution of the heated and non-heated areas of the heat forming roll. Assuming that the heated forming roll is used as figure 1 First hot roll shown, used to produce equidistant and dense slub filaments with cycle lengths.

[0114] The circumference of the heating forming roller is L=720mm, and the surface of the heating forming roller is plated with a heat-conducting ceramic coating with a thickness of 0.2mm by using an ion plating process. The thermally conductive coating on the surface of the heated forming roller is removed by ultra-fine sandblasting to form grooves, and multiple grooves form a non-heating area. Such as Figure 10 As shown, the width of the heating zone formed on the surface of the cylinder is respectively:

[0115] the s 1 = 40mm, s 2 = 40mm, s 3 = 40mm, s 4 = 40mm, s 6 = 40mm, s 7 = 40mm, s 8 = 40mm,...

[0131] Figure 11 is a schematic plan view of the cylindrical outer surface of the thermoforming roll in an unfolded state showing a third distribution of heated and non-heated areas of the thermoforming roll. Assuming that the heated forming roll is used as figure 1 The first heated roll shown is used to produce slub filaments with a period length of thick places and fine spots. In this heated forming roll, the arc length of the non-heating zone is much longer than the arc length of the heat-conducting ceramic layer used as the heating zone.

[0132] The circumference of the heating forming roller is L=720mm, and the surface of the heating forming roller is plated with a heat-conducting ceramic coating with a thickness of 0.2mm by using an ion plating process. In order to form slub filaments with thick places as ground and fine details as spots, the arc length of the non-heated area formed on the circumferential surface of the heated forming roller is several times the arc ...

Abstract

The invention provides a heating forming roller for preparing colorful slub yarn, a spinning device comprising the heating forming roller, a method for manufacturing the heating forming roller and a method for preparing the slub yarn by the spinning device. The heating forming roller comprises a cylindrical main body part, a heating device arranged at the main body part as well as a contact layer, wherein the main body part is covered with the contact layer, so that the contact layer is contacted with to-be-processed yarn; multiple heating zones and multiple non-heating zones are formed on the contact layer, extend in an axial direction of the heating forming roller and are alternately arranged in the circumferential direction, the yarn contacted with the heating zones are heated into a viscoelastic state, the yarn contacted with the non-heating zones keeps a solidification state, and the yarn is stretched into the slub yarn with multiple thick and thin parts which are distributed alternately. Through forming of the heating zones and the non-heating zones on the surface of the heating forming roller, the slub yarn can be formed, the manufacturing technology is simplified, and the manufacturing cost is reduced.

Description

technical field [0001] The present invention relates to a kind of shaping heating roll that is used for forming multicolored slub yarn, especially, relates to a kind of heating shaping roll based on one-step full drawn yarn (Full Drawn Yarn, FDY) slub yarn, and including this A spinning device for heated forming rolls, a method for manufacturing heated forming rolls, and a method for producing slub yarns using the spinning device. Background technique [0002] Colorful slub yarn refers to the filament yarn that has the characteristics of thickness change, crystal orientation change, dyeing depth change, boiling water shrinkage change, initial modulus change and other characteristics in the length direction of a single filament fiber inside the filament yarn. The traditional process is formed by a non-uniform spinning-stretching process, and the filaments with the above-mentioned non-uniform structure (Thick&Thin) characteristics are usually called colorful slub filaments. ...
