Wool straight off a sheep,known as"greasy wool“,contains a high level of valuable lanolin,as well as the sheep's dead skin and sweat residue,Before the wool can be used for commercial purposes,it must be scoured,a process of cleaning the greasy wool.Scouring is complicated as an industrial process using detergent in specialized equipment.Then greasy wool will be turned out as white wool.
The project will adopt latest automatic scouring system,it includes greasy feeder,double drum opener,weighbelt,infeed conveyor,washing bowls,squeeze presses,drum dryer,scoured wool opener duster and wool grease recovery plant. The machine is equipped with detergent and PH systems, wool scouring electrical control system,dirt loops system.
The top-making stage essentially prepares the wool for the spinning process,During this process,all fibres are parallel to each other,any short fibres and residual contaminants have been removed;and the sliver formed has a uniform weight per unit length.The top-making process comprises three main steps,which includes Carding,Gilling and Combing.
The project will adopt world-famous machines,such as Italian OMMI blending system,Italian Octir Cards and French NSC gilling machine and combing machineOMMI Wool Blending system is composed of opening,blending,feeding conveyor,automatic bin emptier.
Each single part of Octir Woollen carding sets is produced in Italy and tested to assure the highest reliability and longevity on the heaviest working conditions.Octir is the only company that still manufactures the large dimension parts, such as main and side frames,in cast iron and submits them to a long natural seasoning,to guarantee long dimensional stability and less vibration,and finally the most even yarn during time.
Cashmere is harvested from the goats during their annual molting season through the shedding or the shearing of their down. Cashmere washing is a process of cleaning grease,sweat residue,weeds and other impurities.
Cashmere carding is a process of removing goat hair ,kemp hair,goat’s dead skin from scouried cashmere,then we get dehaired cashmere.
This machine is suitable for carding cashmere, camel hair, yak hair and other raw materials. The cleaned cashmere initially opened by the eco wool machine is evenly fed by the automatic wool feeder of this machine, and then opened, combed, roughened and impurity are removed step by step to make quasi cashless cashmere with high cashmere content for further carding in the next process to make standard cashless cashmere. The machine is mainly composed of two parts: opening carding part and flat carding roughing part, which are connected by a flat curtain in the middle.
Shearing is important and precise process for worsted wool fabrics, which include four shearing heads to treat at three face side and one back side of fabrics, the PC control panel control and monitor the rotating speed of shearing cylinder, velveting brush by inverter, as well as shearing height, which the precision allows 0,03 mm, thanks for exclusive shearing group with vibration free, stable selvedge detector, reliable fabrics thickness measure sensor, seam detector and fabrics tension regulating with control systems.
The scouring process to be needed for worsted wool fabrics to clean the fabric and enhance the handling which the elastic with shine to be given by wool fiber, in order to have rich softness, hygiene, storage, eliminate mildew, worm, the fabrics with pile surface should be given by force treatment under demand condition of temperature and humidity, to has the dimension shrinkage, enhance the thickness & unit weight, construction compactly, fully pile at the surface to cover the weft/warp construction, thanks for the combined milling and scouring machine which can be given scouring and milling treatment.
The project schedule to install milling & scouring machine with multi functions of light and heavy milling, high speed scouring at 0-400 mts/min regulating, to has the high working efficiency, stable quality with improve handling and reduce cycle time.
Decatizing proposed to wind the fabric with wrapper at the large diameter perforated drum and introduce the steam in/out or out/in at desire the condition of temperature and tension, to has the fabric fixing with flatting, in order to has dimension fixing, improve shine and softness for the fabrics.
The project propose to install decatizing machine with main parameters settting such as wrapper tension, pressure cylinder, decatizing cycle time & steam pressure, and auxiliary setting include cycle time of air suction, evacuation from autoclave, condensate discharge, roll in/out autoclave, and fabrics winding, rewinding, outlet of the fabrics, whole of the setting are controllable by PC and has permanent finishing and setting for the fabrics.
The fabric drying process is necessary after various wetting treatments such as scouring, milling, crabbing, some blend fabrics consist synthetic fibers such as polyester fiber that has to be treated at the condition of high temperature under suitable tension, in order to give fabrics dimensional fixing or construction becomes stabilities.
The project considers to install multi-layers stenter, to achieve drying, hot setting, resin curing, it is by gas heating to has the recipes repeatability thanks for advanced automatic recipes management system.
The function of worsted spinning frame is drafting roving to the yarn with required count, and applying twist to the yarn in order get certain strength and elasticity, finally the yarn are wound on the spinning tube in order to be processed for downstreams.
It’s planned to import ring frame from Zinser Germany in this project. Electric drafting, E-control ring rail movement, frequency speed regulation of spindles etc. advance technologies are used in Zinser Ring Frame. It realize the intelligent control functions of spinning. The important technological parameters such as spindle speed, ring rail stroke, yarn twist, drafting fold etc. can be adjusted from control panel, no gears change is necessary anymore. The high reliable auto-doffing technology can further reduce doffing time, labor cost and increase machine productivity.
Auto winder is an important processing to achieve the yarn free of knot. Large package with free of knot can meet the demands of weaving requirement for fine count fabrics, reduce fabric repairing time, control and clean yarn faults. It improves the quality of yarn and the winding productivity. Auto winder is the essential key equipment for producing high quality worsted fabric.
For this project, it is planning to use electronic yarn clearer and air splicer, which can clean yarn faults effectively, reach high quality yarn piecing joint as well as high success rate of piecing.
Rapier loom can weave different fabrics of various weft density, warp density and pattern through flexible rapier, let off, shedding, insertion, beat up and take up devices.
In this project, we plan to import Picanol OptiMax-i rapier loom to weave worsted fabric. This loom can reach a speed of 500 rpm and an insertion rate of 1700 m/min. It has characters of assembly modularity, high quality, low energy cost, automatic operation, intelligent control system and optimized weaving etc.
The advantages of automatic clothing hanging production system: Supporting multi-order,multi-style,small batches production, Increase or transfer the staff flexibly,and good for improving the production process, Shorten the production cycle, Increase the highest production efficiency above 30% under the reasonable arrangement of production process, Easy for real-time production information management, improving the quality properly,etc.
