Problems solved by technology

[0006] However, conventional long-short composite spinning has the problems of requiring an electrostatic generator and high manufacturing costs (Patent Document 1). The problem that the multifilament fiber partly protrudes to the outside (Patent Document 2), and the problem that the variegated yarn structure is difficult to unwind in normal use (Patent Document 3), etc.

Embodiment 1）

[0081] (1) Manufacture of long-short composite spinning

[0082] The long-short composite spinning of this embodiment is for single-yarn fabrics. pass Figure 2~3 The method shown produces long-short composite spinning. A thick thread of 3.3 metric count (3030 deci tex) of merino sheep wool was supplied as the short fiber bundle 15, and it was drafted to 14 times in the draft zone of the worsting machine. Multifilament fiber 16 Polyethylene terephthalate (PET) multifilament fiber (total fineness: 33 deci tex, number of filaments: 12) is supplied to the upstream of the front roller in a tension-free state (0 to 6.5g) side. Then, on the clamping line of the front roller, the PET multifilament fiber is superimposed on the drawn wool fiber bundle, followed by real twisting to produce long-short composite spinning. The resulting long-short composite spinning is 40 metric count single yarn (expressed as 1 / 40, 250 deci tex), the number of twists is 630 times / m (Z twist, the windi...

Embodiment 2）

[0086] The long-short composite spinning of this embodiment is for ply yarn fabric. pass Figure 2~3The method shown produces long-short composite spinning. As the staple fiber bundle 15, 61% by mass of merino sheep wool and 39% by mass of PET staple fibers (fiber length: 89 mm, single fiber fineness: 3.3 deci tex) were supplied, and thick yarns of 3.3 metric count (3030 deci tex) were supplied. The draft zone of the spinning machine is drafted to 19 times. Multifilament fiber 16 Polyethylene terephthalate (PET) multifilament fiber (total fineness: 33 deci tex, number of filaments: 12) is supplied to the upstream of the front roller in a tension-free state (0 to 6.5g) side. Then, on the clamping line of the front roller, the PET multifilament fiber is superimposed on the drawn wool fiber bundle, followed by real twisting to produce long-short composite spinning. The resulting long-short composite spinning is 52 metric count single yarn (expressed as 1 / 52, 192.3deci tex), t...

Embodiment 3）

[0100] Silk raw silk fiber (total fineness: 16 deci tex, number of multifilaments: 7) was used as the multifilament fiber, wool was used as the short fiber, and 100 metric count single yarn (expressed as 1 / 100, 100deci tex) long and short composite spinning. The twist number of the obtained yarn was 1000 times / m (winding pitch of Z-twisted multifilament fiber: 1.00 mm), twist coefficient K was 100, wool was 82% by weight, and silk raw silk fiber was 18% by weight. Knitted fabrics are made using this long-short composite spinning. Using a 30"-32 needle and row loom, weave into a smooth weave. The number of wales of the braided fabric is 28 / inch, the number of rows is 24 / inch, and the mass per unit area is 176g / m 2 .

[0101] The resulting braid is sewn into a sweater. This knitted sweater has a warm feeling and a very soft touch, and can be worn in the three seasons of autumn to spring. It is light in weight, easy to move around, strong enough to be worn for a long time, wa...

Abstract

The invention provides a length composite spinning and making method thereof, and cloth and cloth material fiber products using same; the length composite spinning is characterized in that a multicord fiber and a short fiber is excellent in consistency, fine wool is less, pilling hardly happens, and handfeeling is soft; the multicord fiber (22) and the short fiber (21) of the length composite spinning (20) are integrated and twisted; when observing a crossing section, the multicord fiber (22) is contained in the length composite spinning (20) and concentrated in a periphery portion; when observed from a side face, the multicord fiber (22) is twisted along a twisting direction of the length composite spinning (20); the making method comprises the following steps: supplying the short fiber bundle to a draft area of a ring spinner; supplying the multicord fiber to an upstream side of a front roller in a tension-less state; stacking the multicord fiber on the drafted short fiber bundle on a clamping line of the front roller, and twisting is carried out.

Description

technical field [0001] The present invention relates to long-short composite spinning ("spinning" is also referred to as "spun yarn") comprising multifilament fibers and short fibers, a method for producing the same, and fabrics and textile products for clothing using the spinning. Background technique [0002] Since long-short composite spinning can utilize the advantages of multifilament fibers and staple fibers, various proposals have been made. For example, the following methods are known. [0003] (1) A method of electrically splitting multifilament fibers, twisting them with short fibers, and producing a uniform blended fiber structure (Patent Document 1) [0004] (2) A method of twisting a single-yarn fiber as a long fiber as a core and spinning fibers as a short fiber as a sheath and covering the outer periphery to produce a core yarn of a core-sheath structure (Patent Document 2) [0005] (3) A method of blending multifilament fibers and staple fibers in differen...
