Embodiment 1

[0015] A preparation method of ramie fancy yarn-dyed fabric, using 36Nm long-fiber ramie yarn as raw material, including the following steps:

[0016] Warp and weft fancy yarn treatment: 36Nm single yarn is dyed, and then combined with a dyed yarn and a white yarn. After a two-for-one twister, the twist is 420. The fancy yarn is used as the warp yarn for the fabric. Two-for-one twisting of two yarns of the same color is used to make warp yarns of the same color and weft yarns are generally dyed with two white yarns twisted.

[0017] Yarn-dyed treatment: After the warp and weft yarns are prepared, the yarn-dyed process is used to sequentially divide the warping-sizing-reed-weaving-repair weaving-post-treatment process; the post-treatment process is: singeing-desizing-boiling Refining-adding softener-stenter setting-pre-shrinking-rolling-into a package. Adding a softener is commonly known as soft.

[0018] Because of the long hairiness of ramie, it is usually impossible to weave by c...

Embodiment 2

[0021] A method for preparing ramie fancy yarn-dyed fabric, which uses 24Nm long-fiber ramie yarn as raw material, and is characterized in that it comprises the following steps:

[0022] Warp and weft fancy yarn treatment: 24Nm single yarn is dyed, and then combined with a dyed yarn and a white yarn. After twisting by a two-for-one twister, the twist is 420. The fancy yarn is used as the warp yarn for the fabric. Two-for-one twisting of two yarns of the same color is used to make warp yarns of the same color and weft yarns are generally dyed with two white yarns twisted.

[0023] Yarn-dyed treatment: After the warp and weft yarns are prepared, the yarn-dyed process is used to sequentially divide the warping-sizing-reed-weaving-repair weaving-post-treatment process; the post-treatment process is: singeing-desizing-boiling Refining-adding softener-stenter setting-pre-shrinking-rolling-into a package. Adding a softener is commonly known as soft.

Abstract

The invention relates to the technical field of clothing fabric preparation, and provides a method for preparing ramie fancy yarn-dyed fabrics, using 36Nm or 24Nm long-fiber ramie yarn as a raw material, treating the warp and weft yarns with the fancy yarn, adopting yarn-dyed technology, and sequentially warping in strips - Sizing - Denting - Weaving - Repairing - Post-processing; post-processing: Singeing - Desizing - Scouring - Adding softener - Stentering - Preshrinking - Rolling - Packing. In the present invention, through the special weaving environment, size formula, coating sizing and post-treatment process, while retaining the advantages of the ramie fabric such as breathability and coolness, sweating and non-stickiness, anti-mold, etc., it improves its rough hand feeling and insufficient softness, etc. The problem is to make the fabric meet the needs of the high-end market.

Description

Technical field [0001] The invention relates to the technical field of fabric preparation, in particular to a preparation method of ramie fancy yarn-dyed fabric. Background technique [0002] The fiber length of ramie fabric is several times longer than that of cotton. The ramie fiber after degumming processing has good luster and whiteness. Ramie fabric is characterized by breathability and coolness. This is mainly due to the large gaps in its structure, so it is very breathable, absorbs water and has high moisture dissipation efficiency. Compared with cotton, ramie fiber is more than 7 times stronger than cotton and has low extensibility. , Light, about 20% lighter than cotton, and not afraid of insects and mold. [0003] The shortcomings of ramie fabric are: rough hand feel, not slippery and comfortable to wear, easy to wrinkle, poor drape; hemp fiber is hard steel and has poor cohesion. How to keep its own advantages while improving its rough hand feel and not soft enough is ...
