Optimising Yarn Preparation with New Cross-Winders.

The Hacoba H2000 and H2200P cross winding machines' technological and economic advantages optimize the yarn preparation process. The H2000 random winding machine for cones and cylindrical packages has a two sided or single sided creel layout, grooved cylinders, flange mounted three phase motors, frequency controlled speed regulation, and ..

Optimum Drafting Zone to Produce Quality Yarns in LG5/1 Ring Frames.

Researchers investigated the effect of several ring spinning machine components--guiding elements, drafting, and winding systems--on yarn quality. An experiment entailed spinning three types of Ne 40/1 yarn (cotton carded, cotton combed, and 55/45 polyester/viscose blend) and testing the yarns for Uster percentage and imperfections, singl..

High-Performance Air-Covering Machine.

Scharer Schweiter Mettler AG's DP1-C Digicone uses an air jet to combine two or more yarns into a single yarn with new properties. The air covering process uses higher production speeds and consumes less energy to lower production costs by up to 60 percent. The integrated rotating ceramic yarn guides allow gentle processing of the yarns. ..

Worsted Yarn Spun on the Cotton System.

Ki Whan Kim of the Hanoi Spinning Company Limited patented a new process to manufacture worsted wool yarns on the cotton system at a lower cost with uniform staple lengths. The system includes drawing, roving, and ring spinning machines. A recess cut into the boss deflects the wool sliver, whereas the remaining section of the roll operate..

Automated Sliver Can Handling System.

Cantrac is an automatic circulating system for carrying sliver cans to open end spinning machines or speed frames. The fully automatic system is self contained, requiring the operator to monitor only the replacement of empty cans with full ones in the appropriate creel channels to ensure the number of cans in circulation remains constant...

ComforSpin: A New Spinning Process Makes Its Appearance.

The spinning machine manufacturer Rieter developed a ring spinning process that results in greater yarn quality than conventional ring spun yarns. The comforSpin process uses a pneumatic condensing zone after the main drafting process. The process yields a virtually ideal yarn structure. The new Com4 brand yarn has higher tensile strength..

Effect of Strand Spacing and Twist Multiplier on Cotton Sirospun Yarn.

Researchers investigated how such spinning variables as strand spacing, twist level, and spindle speed affect spinning geometry; the effect of variations in strand spacing and twist factor on the tenacity, hairiness, and abrasion resistance of cotton Sirospun yarn; and the trapped strand twist. Increasing the strand spacing from 3 millime..

Automatic Textile Blowing-Room Machinery.

Ming Chen Machinery Industrial Company of Taiwan manufactures blow room layouts for ring spinning, open end spinning, and manmade fiber extrusion facilities. The company's blowing machinery includes two automatic bale opening machines, premixing hopper feeder, single beater cleaner, MCK super cleaner, AM mixer, VCK super cleaner and flock..

Spinning of Lyocell.

Compared with other cellulosic fibers, the manufacture of lyocell fibers offers reduced energy consumption and a higher level of environmental safety. Optimizing lyocell fiber properties and processing machines decreases problems associated with spinning lyocell fibers. After opening the flocks, the fibers must be mixed and fed to carding..

Entanglement and Neps in Worsted Processing

Researchers tracked neps throughout wool processing, spinning, and weaving to determine the relationship between neps counted in the top and the appearance of the final fabric. Part of the study determined the effects of comb input loading and speed on the generation of fiber faults from recombing through to finished yarns. Data showed th..
