Problems solved by technology

[0003] At present, there is a kind of slub yarn with hemp-like effect on the market, and the slubs are formed by feeding two yarns at the same time, but this preparation process is relatively complicated, the production cycle is relatively long, and more complicated quality control is required in the follow-up process. And the slub formed is relatively thick, so it is not suitable as a yarn for light and thin summer fabrics
[0004] Japanese Patent Publication No. 2000-303287 discloses a polyester fusion-bonded fancy yarn with a hemp-like effect and a processing method thereof. Although the processing technology of the polyester fancy yarn is relatively simple, high-energy consumption and high-temperature setting are adopted. False twist processing method, and difficult to control in production stability

Embodiment 1

[0025] The polyester raw materials of the following two different components are selected:

[0026] Low melting point component: high shrinkage copolyester, softening point 210-230°C; high melting point component: full-dull polyester, melting point 240-260°C.

[0027] 30% by weight of high-shrinkage copolyester and 70% by weight of full-dull polyester are passed through a composite spinning assembly to obtain a bicomponent polyester fiber with a sheath-core structure.

[0028] The two-component polyester fiber of above-mentioned sheath-core structure (low-melting-point polyester is as cortex part, and high-melting-point polyester is core part) is carried out drawing false twist processing, and the condition of processing is as follows:

[0029] Processing speed: 350-450m / min; draft ratio: 1.38-1.48; the first heating box is a 1.2-meter contact heating box, and the temperature setting is: 180-200°C; the second heating box (contact heating box) The temperature setting is: 140~1...

Embodiment 2

[0033] Low melting point component: high shrinkage copolyester, melting point 210-230°C; high melting point component: semi-dull polyester, melting point 240-260°C.

[0034] Others are as in Example 1.

[0035] The physical properties of the obtained fancy yarn are as follows: strength: 1.8-2.3cN / dtex; elongation: 25-35%; boiling yield: 5-6%; average length of untwisted region: 5-15mm; Ratio: 40-60%.

[0036] Plain weave is used for the weaving structure, and the warp and weft yarns are all made of the above-mentioned two-component polyester fusion bonded fancy yarn, which is woven on an air-jet loom. style, while the fabric is light and breathable, suitable for use as a summer fabric.

Embodiment 3

[0038] The polyester raw materials of the following two different components are selected:

[0039] Low melting point component: high shrinkage copolyester, melting point 100-210°C (example 100°C, 160°C, 210°C); high melting point component: full extinction polyester, melting point 240-260°C (example 240°C, 250°C , 260°C).

[0040] 5-40% (example 5%, 20%, 40%) high-shrinkage copolyester and the rest of the full-dull polyester by weight are passed through the composite spinning assembly to obtain the skin-core composite type (or side-by-side composite type, blended fiber type) Composite) structure of bicomponent polyester fibers. In the skin-core composite type, the low-melting point polyester is used as the skin part, and the high-melting point polyester is used as the core part.

[0041] The two-component polyester fiber of above-mentioned sheath-core structure is carried out drawing false twist processing, and the condition of processing is as follows: processing speed: 25...

Abstract

The invention discloses a melting and bond fancy yarn with two-component polyesters, the manufacturing method and the use. Its stock is two-component polyesters fiber and it is made by drafting and false-twisting machining. There are twisting area and no-twisting area with different twisting direction at the same time in the length direction. The twisting area comprises excessive untwisting area and no untwisting area of melting and bond. No twisting area comprises untwisting area. The detail is formed by the no untwisting area of melting and bond, and the slub is formed by untwisting and excessive untwisting areas. The manufacturing method contains choosing polyester stock with two different components, forming compound two-component polyester fiber by compound spinning module, and drafting and false-twisting the compound two-component polyester fiber so on. The yarn in the invention is provided with twisting and no twisting areas with different twisting direction in the length direction, imitating hemp styles and micro concavo-convex feeling in vision after weaving and dyeing, and reasonable manufacturing method.

Description

Technical field: [0001] The invention relates to a fancy yarn and a processing method thereof. Background technique: [0002] The polyester fiber will present a fluffy and elastic form after being processed by drafting and false twisting. The woven or knitted fabrics made of this yarn will have a fluffy and silky touch in hand, and the fabric surface effect after dyeing It is also relatively uniform. Even after the yarn is twisted, the effect of the cloth surface is relatively simple. [0003] At present, there is a kind of slub yarn with hemp-like effect on the market, and the slubs are formed by feeding two yarns at the same time, but this preparation process is relatively complicated, the production cycle is relatively long, and more complicated quality control is required in the follow-up process. And the slubs formed are relatively thick, which is not suitable as a yarn for light and thin summer fabrics. [0004] Japanese Patent Publication No. 2000-303287 discloses a...
