Best splicing methods for traditional and new yarns
Please give guidance to all colleagues in the industry!
1. The yarn splicer is one of the fastest-growing equipment in the modern textile industry
The initial demand for splicers originated from the chemical long fiber production process in the 1960s, when the presence of knots became an undesirable and disadvantageous factor. The successful splicing of short fiber yarns began in the 1970s and 1980s for carpet yarns and coarse wool yarns, but soon replaced the traditional knotting method and became the standard method of splicing yarns. In fact, knotless splicing technology has taken over the market faster than many other innovations in the textile industry: within 3 years about 80% of automatic winders were equipped with splicers. Today, this ratio has exceeded 97%, and only 3% of self-twisting machines still use traditional knotters because they produce yarns that are difficult to twist. Compared with the situation in 1980 when almost 100% of yarns were spliced by knotting, splicing technology can be said to be an innovative technology that has been widely accepted in a very short period of time.
2. Obvious advantages of knotless yarn
Splicing technology greatly benefits the development of the ring spinning process because it no longer has to be constrained by the knots produced when winding low-capacity ring bobbins. In addition, knotless splicing provides a better opportunity to eliminate yarn defects produced on the ring spinning machine and before.
On the other hand, the improvement in the quality and productivity of the downstream processes of spun yarns brought by knotless splicing technology has been widely recognized and appreciated: when yarn users (including knitting and weaving mills) affirm the knotless yarn Advantages (including increased machine efficiency, improved fabric quality and reduced waste, etc.), knotless single yarn is the inevitable choice.
3. Air splicing is a popular yarn splicing technology due to its flexibility, simple operation, high reliability and relatively low maintenance costs.
Although a variety of splicing technologies have been developed since the 1980s, compressed air is used as the splicing media because of its simple operation, reliability and high flexibility that can be applied to various raw materials, yarn counts and twists. Sex is widely used in the industry. Air splicers are believed to ensure stable results over a long period of time. Compared with other splicing technologies, air splicers are easier to maintain and consume less spare parts.
The air splicers produced by MESDAN are branded JOINTAIR, which has been widely recognized in the industry.
4. Due to the rapid development of science and technology in the past 25 years, almost all yarns produced today can be spliced on automatic winding machines, and can be satisfactorily adopted by downstream processes
Due to its extensive experience and superior technology, MESDAN has been at the forefront in the development of splicers and is recognized as a leader in the industry. Since the launch of the original splicer, MESDAN has always been a reliable supplier to famous machine manufacturers and maintained a stable partnership with various users to improve existing splicing technology and provide Develop new splicers for new types of yarns. This long-term cooperation and exchange with machine manufacturers and yarn users has given us a unique know-how that helps us offer a wide range of splicing solutions for almost all yarns.
5. With the application of water mist and hot air, the special air splicer can splice most new (non-traditional) yarns
In order to splice special yarns, ordinary air splicers can be equipped with special components, or other special splicers can be used, such as water mist splicers (using water + air as the splicing media) and hot air splicers ( Heating the air) is.
1) Ordinary air splicers (such as the 498Q type for ESPERO winding machines and the 690 type for ORION winding machines) can splice almost all pure cotton, chemical fiber, wool and various blended single yarns (for example: just adjust With a few settings, it can be changed from twisting 8-count cotton yarn to 110-count cotton yarn); if the air twisting chamber is replaced, the same splicer can even splice most spandex core-spun yarns.
2) The water mist splicer can splice all pure cotton and blended strands, open-end yarns, and even compact yarns. It is also the best choice for splicing denim coarse yarns and cotton/spandex core-spun yarns, and the only solution for splicing linen yarns and mercerized cotton yarns.
3) The hot air splicer can improve the splicing effect of single and double woolen yarns, siro spinning and high twist worsted yarns.
4) For splicing highly elastic yarns and sewing threads, we can also provide special splicers.
6. Recent focus: 498Q type splicer
Type 498Q air splicer is a new type of splicer developed specifically for ESPERO winding machines produced by SAVIO and Qingdao Hongda. It has been launched on the market for nearly two years to replace the old model: 490L, and 490L Has been eliminated and is no longer in production. Our intention is that users of ESPERO winding machines can use this new splicer, like the splicer installed on SAVIO’s ORION winding machine, to splice ordinary yarns and yarns. The same excellent effect can be achieved with spandex core-spun yarn. The 498Q air splicer can completely replace the 490L!
7. Important tips
In the automatic winding machine process, if you want to achieve its optimal function, each splicer must:
A) Stable performance can be maintained on each ingot;
B) Frequent maintenance.
Even if only one or several twisters are insufficiently functionalIt is enough to destroy the quality of the entire batch of yarn, exposing the user to huge risks of returns and claims.
Here are some of our top tips:
1) Monitor the action cycle of the splicer from the winding machine head computer to determine possible damage to some twisters;
2) Frequently check the strength of the spliced section (Mesdan’s portable joint strength meter is a good tool for automatic winding workshops);
3) Replace damaged splicer parts in a timely manner and use original MESDAN spare parts to ensure that each splicer can operate effectively, reliably and for a long time.
8. In addition to single yarn winding, knotless splicing is required when yarns are broken or need to be connected in many textile processes
The quality of the yarn must also remain stable in the downstream processes after winding. In addition to low end-break rates, knotless splicing certainly improves yarn quality. In addition, if the strands are knotted, the knot size will be quite large, so it will be regarded as a defect, and it will also cause breakage in the downstream process.
These downstream processes that require knotless splicing usually include doubling, ply twisting, shaking of hanks, hank winding, warp drawing, etc. In addition, the weft changing device of the loom and the “end-to-end connection” on the creel of the knitting machine also have such needs. In today’s highly competitive open market, the supply of knot-free strands has become an important added value in the overall yarn quality assessment. For example, in Pakistan, knot-free splicing is definitely required in the two-for-one twisting process to maintain its competitiveness. So far, more than 1,000 double twisting machines in the country have been equipped with MESDAN water mist splicers.
In this area, MESDAN can provide manual splicing solutions in all downstream processes after single yarn winding, including the rewinding process after ring twisting, to ensure that 100% supply can be achieved. One hundred knotless veils for the textile industry. e9ccdAH
