阅读说明：本技术 一种荷兰绒坯布的生产工艺 (Production process of dutch velvet grey cloth ) 是由 王满如 于 2019-10-18 设计创作，主要内容包括：本发明公开了一种荷兰绒坯布的生产工艺,面纱选用半光扁平DTY丝,底纱选用半光圆孔FDY丝,面纱和底纱分别经整经机整经处理后卷绕在盘头上,然后将盘头按比例安装到经编机经轴上织造成坯布。该荷兰绒坯布的生产工艺生产坯布透气性好,方便后道加工。(The invention discloses a production process of dutch velvet grey cloth, wherein semi-smooth flat DTY (draw textured yarn) yarns are selected as surface yarns, semi-smooth round hole FDY yarns are selected as bottom yarns, the surface yarns and the bottom yarns are respectively wound on a pan head after being subjected to warping treatment by a warping machine, and then the pan head is arranged on a warp beam of a warp knitting machine in proportion to be knitted into the grey cloth. The production process of the Holland velvet grey cloth has the advantages that the grey cloth produced by the production process is good in air permeability, and the subsequent processing is convenient.)

1. The production process of the dutch velvet grey fabric is characterized by comprising the following steps of: the surface yarn is made of semi-smooth flat DTY (draw textured yarn), the bottom yarn is made of semi-smooth round hole FDY (fully drawn yarn), the surface yarn and the bottom yarn are respectively wound on a disc head after being subjected to warping treatment by a warping machine, and then the disc head is arranged on a warp beam of a warp knitting machine in proportion to be knitted into grey cloth.

2. The manufacturing process of dutch-down grey fabric according to claim 1, characterized in that: the mass percent of the surface yarn is 66 percent, and the mass percent of the bottom yarn is 34 percent.

3. The manufacturing process of dutch-down grey fabric according to claim 1, characterized in that: the surface yarn is fully threaded on the warp knitting machine, and the bottom yarn is threaded on the warp knitting machine one time and is empty.

The technical field is as follows:

the invention relates to the field of spinning, in particular to a production process of dutch velvet grey cloth.

Background art:

the Dutch velvet is usually used as curtain cloth and sofa cloth, and the existing Dutch velvet grey cloth is single in raw material and structure, so that limitation is caused to subsequent production, and the requirements of people cannot be met.

The invention content is as follows:

the invention aims to solve the technical problem of providing a production process of dutch velvet grey cloth which has good air permeability and is convenient for subsequent processing.

The technical scheme includes that the production process of the Dutch velvet grey fabric is provided, semi-smooth flat DTY (draw textured yarn) is selected as the face yarn, semi-smooth round hole FDY (fully drawn yarn) is selected as the bottom yarn, the mass percent of the face yarn is 66%, the mass percent of the bottom yarn is 34%, the face yarn and the bottom yarn are respectively wound on a pan head after being subjected to warping treatment by a warping machine, and then the pan head is arranged on a warp beam of a warp knitting machine in proportion to be knitted into the grey fabric.

Preferably, the face yarn is fully threaded on the warp knitting machine and the ground yarn is threaded empty on the warp knitting machine.

The invention has the beneficial effects that: the prior art is improved, and proper raw materials and proportion are selected for weaving to form the Dutch down grey cloth with good air permeability and convenient subsequent processing.

The specific implementation mode is as follows:

the invention will be further illustrated with reference to specific embodiments:

the production process of the dutch velvet grey fabric comprises the steps of selecting semi-gloss flat DTY (draw textured yarn) yarns as surface yarns, selecting semi-gloss round hole FDY yarns as bottom yarns, winding the surface yarns and the bottom yarns on a coil head after warping treatment by a warping machine respectively, and then installing the coil head on a warp beam of a warp knitting machine according to a proportion to be woven into the grey fabric.

Specifically, the guide bar configuration: GB1 and GB6 are elastic guide bars, GB2, GB3 and GB5 are ground guide bars, and GB4 is a spacing yarn guide bar; configuration of gauge length: setting the distance between the front needle bed and the back needle bed to be 3.5 mm; weaving on a loom: the elastic guide bars GB1 and GB6 fully penetrate into 135dtex yarns of semi-optical flat FDY, the ground guide bars GB2 and GB3 adopt 1-penetration and 1-empty-penetration 48dtex FDY yarns of semi-optical round holes, and the yarn laying number of each guide bar is as follows:

GB 1: (0-0-0-0/2-2-2-2) x 6 full penetration;

GB 2: 2-3-2-3/2-1-1/3-3-3-3/2-1-1/2-3-3-3/2-1-1/1-0-0-0/1-2-2/1-0-0/1-2-2-2/1-0-0/1-2-2// 1 punch 1 empty;

GB 3: 1-0-0-0/1-2-1-2/1-0-0-0/1-2-2-2/1-0-0/1-2-2/2-3-3-3/2-1-1-1; 2-3-3-3/2-1-1-1/2-3-1-3/2-1-1-1//1 crosses 1 empty;

GB 4: (1-0-1-1/2-3-1-1) x 6 full penetration;

GB 5: (1-1-1-0/0-0-1-2/2-2-2-1/1-1-1-2/2-2-1-0/0-0-0-1) x 2 full penetration;

GB 6: (1-1-0-0/0-0-2-2/2-2-1-1/1-3-2-2/2-2-0-0/0-0-1-1) x 2 full penetration.

The invention improves the prior art, selects proper raw materials and proportion for weaving, and forms the dutch velvet grey cloth with good air permeability and convenient subsequent processing. Elongation at break (%): 140.0 +/-12.0, and the air permeability can be improved by more than 19% compared with that of a conventional product.
