Technical Status and Selection Analysis of Rapier Loom


Rapier looms have wide adaptability and high cost performance, and occupy a high proportion in shuttleless looms. This paper will analyze the technical level and development trend of rapier loom at home and abroad, analyze and discuss some problems in the selection of rapier loom, and put forward some suggestions for the application of rapier loom. This paper only takes the numerous rapier looms used in shuttleless looms at home and abroad as an example to illustrate their technical level and selection problems.

Technical Status and Selection Analysis of Rapier Loom

Rapier looms have wide adaptability and high cost performance, and occupy a high proportion in shuttleless looms. This article will analyze the current domestic and foreignrapier loomThe technical level and development trend of rapier loom are analyzed and discussed, and some problems in the selection of rapier loom are analyzed and some suggestions are put forward for the application of rapier loom.

With China's accession to the WTO and the further deepening of the reform of the enterprise system, China's textile industry is facing opportunities and challenges. The main point of competition will be the adjustment of product structure and the improvement of product grade and quality. Reforming traditional handicrafts with new technology is the only way for the development of productive forces. Especially in the rapid development of science, technology update speed today. Therefore, the traditional textile industry also needs to be transformed step by step. How to speed up the pace of technological progress and increase the proportion of China's shuttleless looms is the fundamental shortcut to solve the product. This paper only takes the numerous rapier looms used in shuttleless looms at home and abroad as an example to illustrate their technical level and selection problems.

1. Overview

According to incomplete statistics, by the end of 2004, China had nearly 1.76 million looms of various types, including about 1.09 million shuttle looms, 1.03 million shuttle cotton looms and more than 675000 shuttleless looms. (Among them, there are 720000 projectile looms, 121000 rapier looms, 315000 simple GA74 series rapier looms and 85000 air-jet looms), and the utilization rate of shuttleless looms is 24.83. GA74 series cotton looms are still widely used in the cotton weaving industry.

In the weaving industry, private enterprises have accounted for more than 2/3 of the whole industry through structural adjustment and system adjustment, and the proportion of shuttleless looms in coastal areas has accounted for more than half of the country, and the ability of products to adapt to the market has been improved. There are also a considerable number of enterprises have carried out joint ventures, restructuring and equipment upgrading, with large-scale production capacity of fabrics, and most of the products are exported. However, the country is still dominated by low-level production capacity, high-level production capacity is insufficient, products have not changed for many years, and the level of supporting and serialization is very insufficient.

2, the current domestic and foreign rapier loom and supporting equipment technical level

In a shuttleless loom,rapier loomIt is a universal and reliable loom for weaving small batch, medium batch and frequent replacement varieties. The price of rapier loom is lower than that of projectile loom. In recent years, with the improvement of the weft insertion mechanism, the weft insertion speed has increased, but the acceleration change is relatively gentle; the structure of the rapier weft clamping movement can be applied to yarns of different materials and structures, and there is no need to exchange the sword between 0.7tex ~ 3300tex. The range of fabrics processed by rapier loom has developed from medium-thick fabrics to light and thin fabrics, from clothing fabrics to decorative and industrial fabrics, from single-layer fabrics to pile and double-layer pile fabrics, and from narrow width to 4.6 meters. The breadth of the rapier loom has developed from low speed to high speed. At present, the weft insertion speed of rapier looms has exceeded 1500 m/min, and the color selection of weft yarns has also developed from a single color to about 16 colors, and the adaptability of varieties is not as good as other shuttleless looms.
