Description

TECHNICAL FIELD

[0001] The present application belongs to the field of fancy yarns, and particularly relates to a weavable loop yarn. BACKGROUND

[0002] Loop yarn belongs to one kind of fancy yarns, and the fancy yarns are mainly composed of core yarn, decorative yarn and fixed yarn. The core yarn and the fixed yarn are often made of chemical fiber filament or acrylic wool spinning raw material to be used as yarns, the decorative yarn is the part of loop on the loop yarn, and can be yarns of various wool spinning raw materials or cotton spinning roving. The finished loop yarn has regular loop effect.

[0003] In the prior art, the fixed yarn is often used to fix the loop effect of the fancy yarn and the core yarn, for example:

[0004] A double-color loop yarn (application number: CN202120233373.9) comprises a core yarn, a first decorative yarn, a second decorative yarn and a pressing yarn. The decorative yarn is spirally wound on the core yarn, the core yarn forms loops in the radial direction, and the pressing yarn is arranged to press the two decorative yarns.

[0005] A loop yarn (application number: CN201720137100.8) comprises a core yarn, a fixed yarn and a decorative yarn. The decorative yarn is tightly attached to the core yarn, the core yarn forms first and second annular loops in the radial direction, and the fixed yarn is spirally wound along the core yarn in the axial direction to realize the tight attachment of the decorative yarn to the core yarn.

[0006] An inner bundle beauty loop yarn (application number: CN200820184183.7) comprises a floating yarn, a core yarn and a pressing yarn. The floating yarn is wrapped around the core yarn and forms loops in the radial direction of the core yarn, and the pressing yarn presses the floating yarn and the core yarn together in the axial direction of the core yarn.

[0007] A three-in-one fancy yarn (application number: CN200120044163.8) displays three kinds of patterns of loop yarn, wave yarn and big-belly yarn on one yarn. The three kinds of patterns are composed of a core yarn, a decorative yarn and a fixed yarn, and respectively form a section of loop yarn, a section of wave yarn and a section of big-belly yarn. SUMMARY

[0008] The present application provides a weavable loop yarn to overcome the shortcomings of the prior art.

[0009] The technical scheme of the present application is as follows:

[0010] A weavable loop yarn is composed of a core yarn and a decorative yarn. The core yarn is an elastic filament, and the decorative yarn is a chemical fiber filament. The decorative yarn is distributed around the core yarn to form a loop effect.

[0011] The core yarn and decorative yarn are woven together in one go to form a loop effect. The size and density of the loops are controllable. The size of the loops can be adjusted by the feeding speed of the decorative yarn, and the density of the loops can be adjusted by the number of decorative yarns and the weaving angle.

[0012] The beneficial effects of this invention are as follows: This invention uses a braiding machine to weave boucle yarn without a fixed yarn. The yarn is formed in one step, with the decorative yarn distributed around the core yarn to create a boucle effect. The yarn is fluffy, has a strong three-dimensional effect, a soft hand feel, and excellent elasticity. This structure achieves fancy effects with only two components: the core yarn and the decorative yarn. It breaks through the conventional structure of core yarn, fixed yarn, and decorative yarn required for fancy yarns. Furthermore, the boucles can be distributed in a single layer or layered, allowing for single-layer same color, single-layer multi-color, multi-layer same color, and multi-layer multi-color boucle effects. The preparation method is simple, and it is applicable to a wide range of raw materials, showing promising application prospects in the fields of clothing and decorative textiles. Attached Figure Description

[0013] Figure 1 This is a diagram of the loop yarn structure.

[0014] Figure 2 This is a flowchart of the boucle yarn manufacturing process. Detailed Implementation

[0015] like Figure 1 As shown, the woven loop yarn in this embodiment consists of a core yarn 1 and a decorative yarn 2. The decorative yarn wraps around the core yarn, creating a loop effect in the radial direction of the core yarn. The core yarn is an elastic filament, and the decorative yarn is a synthetic fiber filament. The decorative yarn is distributed around the core yarn to form a loop effect. The core yarn and decorative yarn form a loop effect in one weaving process. The size and density of the loops are controllable. The size of the loops can be adjusted by the feeding speed of the decorative yarn; when the amount of decorative yarn fed is greater, the loop size is larger. The loop density can be adjusted by the number of decorative yarns and the weaving angle; when the number of decorative yarns is greater, the loop density is greater.

[0016] The core yarn also serves to hold the yarn in place, and there is an even number of core yarns. The even number of core yarns, due to their winding, acts as a bond, allowing the decorative yarn to better integrate with the core yarn. The decorative yarn can be either twisted or untwisted, and there can be one or more strands. The number of decorative yarn strands determines the number of loops around the core yarn.

[0017] The decorative yarn and the core yarn have different elasticity, and the decorative yarn is stacked symmetrically or asymmetrically around the core yarn in a loop shape.

[0018] When the same color decorative yarn and core yarn are selected for weaving, the loops arranged along the direction of the core yarn will produce a single layer of the same color or multiple layers of the same color overlapping effect; when different colors decorative yarn and core yarn are selected for weaving, the loops can present a variety of appearance effects such as single layer of the same color, single layer of multiple colors, multiple layers of the same color, and multiple layers of multiple colors.

[0019] likeFigure 2 The weaving process of the present application is as shown:

[0020] The core yarn 1 and the decorative yarn 2 are respectively wound by using a winder;

[0021] The raw material bobbin form is converted into a winding suitable for the weaving machine;

[0022] The core yarn and the decorative yarn are respectively placed on the weaving machine (1 head, 16 spindles), and the speed of the bobbin is set to 30 revolutions per minute; the loop yarn is woven into shape and wound on the bobbin.

[0023] In summary, for the preparation of fancy yarn, it is usually necessary to introduce a fixed yarn to realize the shaping requirement of the fancy effect. The present application selects two components of core yarn and decorative yarn, which can simultaneously satisfy the fancy effect and its fixing function when woven into shape, greatly shortening the process flow in one-time forming. The equipment that can be used for weaving can be used for the processing of the loop yarn, and the process setting and operation are relatively simple.
