ITMA exhibition has always been a grand event for textile machinery manufacturers, and also a new technology conference for some world-famous textile machinery enterprises. In this ITMA 2019 exhibition, the majority of knitting machinery manufacturers participated in the exhibition with a large number of prototypes, complete varieties, various functions and many technical highlights. The new knitting machine is developing rapidly in the direction of high production efficiency, variety differentiation, management network and product intelligence. The main development direction of knitting equipment technology in recent years is described from six aspects.
Knitting short process production technology
Meyer West, Germany, has demonstrated a circular knitting machine integrating spinning and knitting, which can shorten the production process and obtain special knitted products. The spinit 3.0 e-spinning knitting one-sided jacquard circular weft knitting machine exhibited by Meyer West, which integrates spinning and knitting, saves the process of ring spinning, cleaning and rewinding, greatly shortens the process flow, can sense and automatically clean online, can realize the real-time adjustment of yarn ratio, linear density and other yarn forming processes, and can form stripe, regular or irregular jacquard And so on.
Knitting forming technology
With the increasing shortage of labor and the increasing cost of labor, coupled with the high intensity of some posts in the knitting production and processing process, the production of labor is becoming more and more scarce. In this background, knitting forming and weaving technology has become a promising development direction. In terms of circular weft knitting equipment technology, the representative sm8-tr1s single-sided seamless circular knitting machine exhibited by SANTONI can be used for knitting underwear, Outerwear, sportswear and other fully formed seamless clothing; in terms of horizontal knitting equipment technology, the representative ADF 830-24ki W and CMS 830ki woven wearable computer horizontal knitting machines exhibited by Stoll, mach2vs213 fully formed computer horizontal knitting machine exhibited by Daojing Machine, respectively, can complete the forming knitting of the whole sweater clothing through the weaving wearable technology and the whole garment four needle full forming knitting technology, and can save the expensive and time-consuming process such as back-to-back stitching, so as to realize the true full forming three-dimensional knitting.
Warp knitting traverse control technology
With the continuous development of computer technology and motion control technology, they have been widely used in various control and driving mechanisms of knitting machines, such as the head drive / traverse / yarn feed of computerized flat knitting machines, the warp feed / guide bar traverse / pull of warp knitting machines, etc., among which the electronic guide bar traverse control of warp knitting machines requires high precision and fast response, which has restricted the overall CNC of high-speed warp knitting machines for many years Bottleneck. The hks3-mon high-speed tricot warp knitting machine exhibited by kalmyer in this exhibition is equipped with electronic guide bar traverse device, and the production speed can reach 2900 R / min, which clears the final obstacle for the full realization of computerized control of three guide bar warp knitting machine.
Warp knitting 4D jacquard technology
Rdpj 6 / 2 El double needle bed double jacquard warp knitting machine exhibited by kalmyer in this exhibition can be used to produce fabrics with various 4D patterns on the front and back, and the shape, position and height of concave and convex three-dimensional patterns can be adjusted freely; small and flat relief appearance or large concave and convex vertical design can be produced; in addition, mesh can be freely distributed according to the design needs to obtain penetration Air or light transmission effect.
Knitting intelligent sensor technology
In recent years, with the continuous improvement of the material living standard and the continuous progress of science and technology, the application of intelligent clothing is more and more extensive, and the market potential is huge. Carl Meyer showed off a smart T-shirt made of pure warp knitting. This T-shirt is based on the two-way elastic fabric of warp knitting. In the warp knitting production, the electronic components such as warp knitting temperature sensor, warp knitting humidity sensor, textile flexible electrode and textile wire are weaved by the functional fiber through the steel wire jacquard technology at the required exact position, and the electronic components are integrated into the whole flexible sensor system, thus forming a piece of personnel that can be used to monitor the movement Smart clothing for heart rate, body temperature and body surface humidity.
Knitting Internet application technology
Kalmyer has demonstrated its increasingly mature km.on remote service system, such as hks3-mon high-speed tricot warp knitting machine and RSJ 4 / 1 on jacquard warp knitting machine, which can be connected to the km.on system network, and can connect the machine to the protected cloud safely through k.ey, so that users can view the actual production data of the current factory at any time and place, and can easily realize remote operation Service and maintenance, effectively improve the production efficiency of the machine.
Stoll has demonstrated the knitelligence ® system, from fast photo prototypes to weaving procedures, with personalized push and pattern and production management covering the entire sweater production chain. Artwork processes the design pictures, GKS weaves and pushes the codes, automatically creates m1plus and sin files, enters the PPS production planning system, controls, plans and optimizes the production, and finally conducts the production according to the demand in EKC (extended weaves control system), and the intermediate process does not need human control.
