喷水织造“毛丝”和“断经”六原因及六对策/Six reasons and six countermeasures for water-jet weaving "wool" and "broken"

一、产生毛丝和断经的“六原因”

First, the "six reasons" for producing wool and menstruation

 

1、原料物理机械性能不理想,纤维断裂强度偏低,经丝抱合力差,在织造过程中,经不起钢筘、综丝反复摩擦,导致经丝单纤起毛或断头。

1. The physical and mechanical properties of the raw materials are not ideal, the fiber breaking strength is low, and the warp cohesion is poor. In the weaving process, the steel shovel and the healds are not repeatedly rubbed, resulting in the warp single fiber fluffing or breaking.

 

2、整经、并轴工序导丝器起槽、破损或者经丝退绕时被抖牢、缠牢,使纤维强度、伸长受损伤,机械性能恶化,当生产加工张力超过其强力、伸长的屈服值时,导致单纤断裂而断经。

2. Warping, and shaft process yarn guides are grooved, damaged or warp when they are unwound, and the fiber strength and elongation are damaged, and the mechanical properties are deteriorated. When the production and processing tension exceeds its strength and elongation When the yield value is long, the single fiber breaks and breaks.

 

3、织机钢筘、综丝起槽、损伤,经丝经不起其反复高频率摩擦而起毛断头。织机车速越快则经毛断经现象越严重。

3. Looms steel shovel, healds grooving, damage, warp can not withstand repeated high frequency friction and hair break. The faster the speed of the loom, the more severe the warp phenomenon.

 

4、整经机毛丝监测器失灵,让原料自身的毛丝、长结子逃过或者挡车工断经接头时结子太大、太长,织造时经面经丝被缠牢,造成开口不清、拉断头。

4. The warping machine's hairline monitor fails, so that the raw material's own wool and long knots escape or the blocker is too big and too long when the joint is broken. When the weaving, the warp and warp threads are entangled, causing the opening to be unclear. Pull the broken head.

 

5、织机运行,其经丝的开口高度对经毛、断经影响很大,因为织机开口时,经丝的伸长与开口高度成正比,织机的开口高度大,则经丝的伸长大,过大的伸长造成经丝的起毛、断裂。

5. The operation of the loom, the opening height of the warp yarn has a great influence on the warp and the warp, because the elongation of the warp is proportional to the height of the opening when the loom is opened, and the opening height of the loom is large, then the warp of the loom The elongation is large, and the excessive elongation causes the hair to fluff and break.

 

6、织机运行时,综丝的摩擦动程对经丝经毛断经影响也很大。当综框开口时,经丝向综眼前移动,而梭口闭合时,经丝又从综眼中向后移动,这个前后移动的距离,即为摩擦动程。织机连续运转、开口、闭口不断循环,经丝在综眼中不断往复移动而受摩擦。也是造成经毛断经的重要环节。特别是开口高度偏大、开口部件磨损、综框运动不稳、综丝上下运动发荡、织机车速快,经丝经毛断经的现象更严重。

6. When the loom is running, the frictional stroke of the heald has a great influence on the warp of the warp. When the heald frame is opened, the warp yarn moves toward the front of the eye, and when the shed is closed, the warp yarn moves backward from the eye. This distance of movement back and forth is the friction stroke. The loom continuously runs, the opening and the closed loop continue to circulate, and the warp yarn is continuously reciprocated and rubbed in the eye. It is also an important link that causes warfare. In particular, the opening height is too large, the opening parts are worn, the heald frame movement is unstable, the healds are moving up and down, the loom speed is fast, and the warp yarn passing through the hair is more serious.

 

二、防止毛丝和断经的“六措施”

Second, the "six measures" to prevent hairline and menstruation

 

1、根据不同品种及质量要求优选原料。原料进厂后先抽样做物理机械性能测试,其后到织机上纬向喷射,做原料可织性和吸色试样,为原料投产,合理制定整、浆、并工艺参数打下基础。

1. The raw materials are preferred according to different varieties and quality requirements. After the raw materials enter the factory, the samples are first tested for physical and mechanical properties, and then sprayed onto the weaving machine in the weft direction to make the raw materials woven and absorb the color samples, which lays the foundation for the raw materials to be put into production and rationally formulate the whole, pulp and process parameters.

 

2、对整、浆、并工序导丝部件,毛丝监测器、静电消除器、断头自停等装置,要定期检查,发现问题及时处理。起机后,要再次查看,经轴有无毛丝,如有毛丝,及时挑出,并通知前道工序,分析原因。

2. For the whole, pulp, and process guide wire components, yarn monitors, static eliminators, broken heads and other devices, it is necessary to check regularly and find problems in time. After starting the machine, you should check it again. There is no wool in the warp beam. If there is wool, pick it out in time and inform the previous process to analyze the reason.

 

3、加强对钢筘、综丝的质量验收,做好定期检查、保洁、保养等管理工作。

3. Strengthen the quality inspection of steel shovel and heald, and do regular management such as inspection, cleaning and maintenance.

 

4、定期对织机综框开口装置进行检查、整修,防止开口部件磨损,综框运动不稳、综丝发荡。

 

4. Regularly inspect and refurbish the opening device of the weaving machine heald frame to prevent the opening parts from being worn, the heald frame movement is unstable, and the healds are undulating.

 

5、喷水织造在能保证顺利引纬的情况下,开口高度尽量以小为宜。

5. Spray water weaving in the case of ensuring smooth weft insertion, the height of the opening should be as small as possible.

 

6、各道工序挡车工加强质量意识。提高操作技能,经丝断头接头必须理清丝路,接头时做到结子小、短,不脱结。

6. The various process blockers to enhance quality awareness. Improve the operation skills, the wire break joint must be clear the silk road, the joint is small, short, and does not detach.
