Embodiment Construction

[0022] The technical solution of the present invention is described in detail below.

[0023] Example Yarn formation of hollow yarn

[0024] The combed cotton sliver 1 as the outsourcing fiber is fed into the rear roller 3 through the upper bell mouth 2 of the FA506 ring spinning frame for drafting, and at the same time as the 60 core yarn wound on the edged bobbin 4 s The PVA yarn filament 5 is guided by the core yarn unwinding device 6 and the core yarn tension control device 7, and then fed into the nip of the front roller from the rear 9 sides of the front roller, so that the core yarn and cotton fiber strands merge into twisting area, and finally drawn out by the core yarn guide hook 10 to form the core-spun yarn on the bobbin 11.

[0025] The yarn-forming process parameters of the core-spun yarn can be found in Table 2.

[0026] Table 2 Yarn forming process parameters of core-spun yarn

[0028] The structure of the core-spun yarn obtained is shown in figu...

Abstract

The invention discloses a yarn forming method for hollow yarns, which comprises the following steps: making clad yarns in spinning equipment by using water soluble polyvinylalcohol fibers as core yarns and using comed slivers which are clad by fibers according to a ratio of 12 to 15 g / 10m; dissolving the core in water at the temperature of 5 to 100 DEG C; and obtaining 45s to 10s hollow yarns after the polyvinylalcohol dissolves in water from the clad yarns completely. The hollow yarns made by the yarn forming method of the invention has the advantages that: the volume density of the yarns is lowered by 15 to 30 percent; the apparent volume of the yarn aggrdgate is increased by 15 to 30 percent; the water absorptivity of the yarns is improved by 15 to 30 percent; and the bulkiness is improved.

Description

technical field [0001] The invention relates to a method for weaving fibers, in particular to a method for forming a hollow yarn. Background technique [0002] Blending, intertwisting, and wrapping natural fibers such as cotton, wool, silk, and hemp with artificial fibers and synthetic fibers to change their functionality was the main direction of attack in the 1980s and 1990s. In the 21st century, untwisted yarn products appeared in the products, which once caused a sensation in the looping products. Pure cotton towels use untwisted yarn, and the loops of the towel are extremely fluffy and soft. It is used to wipe the face and clean the body, and it feels extremely soft. It is known as a beauty and skin care towel. However, due to the release of the twist that maintains the cohesion of the fibers, the yarn becomes parallel loose fibers, so it is as soft as cotton wool and loses its structural fastness. Therefore, it is only easy to use dry, which greatly reduces the scope...
