Abstract

The utility model provides a layer-by-layer wrapping four-ply yarn, including the first yarn, the second yarn, the third yarn and the fourth yarn, wherein the first yarn and the second yarn are yarns with the same twist direction, and the first yarn The second yarn is entangled with the twist direction opposite to its twist direction to form a double-ply yarn, and the third yarn is entangled outside the double-ply yarn with a twist direction opposite to the twist direction of the double-ply yarn to form a three-ply yarn. The four yarns are entangled on the outside of the three yarns in a twist direction opposite to that of the three yarns to form four yarns. The utility model first selects two yarns to reversely intertwine to form a double-ply yarn, then uses the third yarn to reversely intertwine with the double-ply yarn to form a three-ply yarn, and finally adopts the fourth yarn to reversely intertwine with the three-ply yarn to form a four-ply yarn Yarn, so that the yarn has the form of strands, can greatly increase the yarn strength, reduce yarn hairiness, and reduce the overall residual torque of the yarn.

Description

A layer-by-layer wrapping four-ply yarn

technical field

The utility model relates to the field of novel yarns, in particular to a layer-by-layer wrapping four-ply yarn.

Background technique

Sirofil spinning is a new type of spinning method developed on the basis of siro spinning. A filament is fed from the front roller without drafting, and is combined with the sliver after the front roller outputs a certain length. The components are twisted directly, and the yarn is formed in one step. Compared with the traditional spinning process, the cascading and twisting process is omitted, and due to the supporting function of the filament and the special yarn structure, the requirements for fineness such as wool can be greatly reduced. This type of product has a unique style, and the fabric's elasticity, wrinkle resistance, drape, air permeability, anti-pilling, and dimensional stability are all superior to traditional products.

In view of this, the utility model provides a layer-by-layer wrapped four-ply yarn, including the first yarn, the second yarn, the third yarn and the fourth yarn, wherein the first yarn and the second yarn are yarns with the same twist direction, The first yarn and the second yarn are intertwined in the opposite twist direction to form a double-ply yarn, and the third yarn is intertwined outside the double-ply yarn with the twist direction opposite to the twist direction of the double-ply yarn to form a three-ply yarn Yarn, the fourth yarn adopts the twist direction opposite to the twist direction of the three-ply yarn to be entangled outside the three-ply yarn to form a four-ply yarn. The utility model first selects two yarns to reversely intertwine to form a double-ply yarn, then uses the third yarn to reversely intertwine with the double-ply yarn to form a three-ply yarn, and finally adopts the fourth yarn to reversely intertwine with the three-ply yarn to form a four-ply yarn Yarn, so that the yarn has the form of strands, can greatly increase the yarn strength, reduce yarn hairiness, and reduce the overall residual torque of the yarn.

Contents of the invention

The purpose of this utility model is to provide a layer-by-layer wrapping four-ply yarn, by first selecting two yarns to reversely intertwine to form a double-ply yarn, and then using the third yarn to reversely intertwine with the double-ply yarn to form a three-ply yarn, Finally, the fourth yarn is reversely intertwined with the three yarns to form four yarns, so that the yarn has the form of strands, which can greatly increase the yarn strength, reduce yarn hairiness, and reduce the overall residual torque of the yarn.

In order to achieve the above object, the technical scheme adopted by the utility model is as follows: a layer-by-layer wrapping four-ply yarn, including a first yarn, a second yarn, a third yarn and a fourth yarn, and the first yarn and the second yarn are The twist direction is Z-twisted yarn, the first yarn and the second yarn are entangled together by S twist direction to form a double-ply yarn, and the third yarn is entangled outside the double-ply yarn by using Z-twist direction , forming three yarns, the fourth yarn adopts S twist direction to intertwine on the outside of the three yarns to form four yarns; or the first yarn and the second yarn are yarns with S twists in the twist direction, and the second yarn The first yarn and the second yarn are entangled together through the Z twist direction to form a double-ply yarn, the third yarn is entangled outside the double-ply yarn with an S twist direction to form a three-ply yarn, and the fourth yarn adopts a Z twist Intertwine over the outside of the three-ply yarn to form a four-ply yarn.

When spinning, the first yarn, the second yarn, the third yarn and the fourth yarn are spun by an ordinary ring spinning machine, and then the double-ply yarn and the three-ply yarn are spun separately by paralleling and corresponding twisting directions. and four-ply yarn.

The advantages and beneficial effects of the utility model are as follows: firstly, two yarns are reversely intertwined to form a double-ply yarn, and then the third yarn and the double-ply yarn are reversely intertwined to form a three-ply yarn, and finally the fourth yarn and the three-ply yarn are used. The yarn is reversely entangled to form four-ply yarn, which makes the yarn have the form of strands, which can greatly increase the yarn strength, reduce yarn hairiness, and reduce the overall residual torque of the yarn.
