The control system is an important symbol of high - end shuttleless loom.The advanced intelligent distributed control system mainly has two functions: loom monitoring and information network management: loom monitoring mainly has real-time monitoring, data monitoring, two-way communication and other functions, is an advanced quality control technology;Information network management Ethernet, CAN bus, fiber optic communication and other components of the local area network, CAN achieve loom group control, real-time weaving parameters CAN use the communication network to achieve global and regional remote control and transmission, CAN timely diagnosis and treatment of problems and faults.
In recent years, domestic high-end shuttle-free looms have adopted multi-cpu distributed control in the control system. In terms of real-time monitoring and data processing functions, the gap with foreign looms has been narrowed. However, the stability and reliability of the information network management technology and the system need to be further strengthened.
Modular design
Modular design fully considers the universality of parts and the convenience of assembly, which can reduce the cost and speed up the market supply of products.At present, European looms are widely used in the concept of modular design, which can be extended and evolved from the original models.In recent years, some Japanese manufacturers have also applied the concept of modular design in the design of water jet loom. Water jet loom is used in some production platforms of air jet loom, thus improving the comprehensive technical performance of products.
Domestic rapier and air jet loom manufacturing is still based on imitation models, limited by this, in the two types of loom in the general, has not yet entered the modular design concept of the field, but the application of universal parts has been involved.
Nc direct drive
In the past two years, the advanced jet and rapier looms have been widely applied to the direct drive technology of the main motor, which has been incorporated into the control system to accelerate the full automation of the loom.With this technology, the main drive system eliminates the main clutch, brake and the slow and weft finding mechanism, and is directly driven by the program digital control, which is conducive to improving the loom speed, operating efficiency, reducing energy consumption and machine material consumption.
Using this driving technology, the main motor is required to have low consumption, high starting torque, good speed regulation performance, frequent starting and braking, and high efficiency.At present, the motors adopted by various manufacturers mainly include switched reluctance motor (Sumo), synchronous variable reluctance motor (DD), independent variable frequency motor, and ac brushless motor (hi-drive).
The new technology
Water jet loom and products
Technology is briefly
Water jet loom is a shuttle-less loom that USES jet water column to draw the weft yarn through the shed.The weft insertion of water jet loom has higher frictional traction force and less diffusivity than air jet loom.
advantage
The width of water jet loom is 230cm~350cm, which can not only weave regular polyester yarn and nylon yarn, but also weave low stretch yarn, strong twist yarn, different shrinkage yarn and super fine denier yarn. The fineness ranges from 10dtex to 167dtex, and the speed of water jet loom can reach 1200r/min.
Examples of application
Super fine denier chemical fiber fabric: in the development process, to solve the strength problem of fine denier 15D, 20D polyester or nylon fabric, at the same time with some printing, dyeing and finishing process, give the fabric fashionable appearance and special functions, improve the added value of the product.
Crepe fabric: crepe DE chine, crepe DE chine, crepe DE Joe fabric, crepe DE chine fabric, etc.Soft linen is composed of a variety of synthetic fiber weaving imitation linen crepe fabric, products are colorful, soft, and excellent permeability, drapability fabric wash and wear, not easy to wear and tear, silken face is double color, a variety of effects such as colour, fillet, has a twill weave, crepe fabric organization, basket weave, the case organization, organize and plainback small jacquard through hole.
Suede fabric: soft silk of fine denier synthetic fiber, woven fabric has a good feel, especially its excellent sense of velvet, can be woven into peach leather fine denier silk, in addition, suede woven with ultra-fine denier silk, is widely used as the fabric of jacket and windbreaker.
Wool - like or hemp - like fabric: a fabric made of wool - like or hemp - like synthetic fibers.Double-color bamboo joint hemp products are woven with two kinds of polyester yarns with bamboo joint effect and woven with warp and weft. After dyeing, the silk face presents a double-color effect. The fabric has excellent drape and air permeability, good drape resistance and smooth hand feel.
Edit comment on
At present, most water jet looms are equipped with two water pumps, which can weave two different weft filaments.The water jet loom is mainly used in the production of synthetic fiber imitation silk, suede, stretch fabric and other products, which can meet the production needs of various kinds of fabric.
Gripper loom and products
Technology is briefly
As the first shuttle-free loom to realize commercial production, the shuttle-free loom is now capable of filling in any order of 6 colors. The shuttle-making machine is electronic, and the position of sensor sensor plate automatically ensures the correct braking and positioning of the shuttle-making machine.
advantage
The width ranges from 190cm to 650cm, and can be woven in multiple pieces. The yarns are suitable for a wide range of applications: 6.4dtex~2000dtex for staple yarns, 12dtex~5550dtex for filament yarns, the density of weft yarns ranges from 0.83 to 181.5 /cm, the insertion speed can reach up to 1200m/min, and the gram weight of fabrics ranges from 40 to 1000g/m2.
Examples of application
With the characteristics of high speed, great power and reliable operation, the gripper loom is especially suitable for weaving wide industrial, construction and agricultural industrial textiles.In the aspect of clothing fabrics, the thin elastic denim produced by the flap-shuttle loom can be woven into light, refreshing and elegant stripes, and can also be woven into or sedate, or lively jacquard, endows denim fabrics with high added value, and improves the grade of products.
