Rabbit Hair-Acrylic Blends.

Rabbit hair is a specialty hair protein fiber than features warmth, soft hand, and luster but lacks good interfiber cohesion, which results in poor spinnability. Acrylic fibers have been blended with rabbit hair to improve the quality of rabbit hair yarns. Researchers blended rabbit hair and acrylic fibers in ratios of 2575, 50/50, and 75..

Model Experiment of Interlaced Yarn. Part 1: Single-Blowing Method

To clarify processing principles of interlaced yarn, researchers examined the effect of air pressure, yarn speed, and feed ratio on yarn tension during processing and the number of resulting tangles. Rather than use a conventional interlacing machine, researchers produced tangling and opening parts in a yarn by aiming an air jet on yarns ..

Automatic Crimping and Innovation for the Future

The Autocrimp system introduced at ITMA 1995 by SCS Consultancy Services of Bradford, United Kindom, is expected to create an entirely new dimension in fiber production. The system automatically provides polypropylene with a three dimension in fiber production. The system automatically provides polypropylene with a three dimensional helic..

Inovation in Draw Texturing.

A steady increase in worldwide production of continuous filament, polyester, and nylon yarns has resulted from the growing demand among developing countries for apparel made from textured yarns. The development of the high temperature 'short' oven has inaugurated a new phase in texturing machine technology. Menegatto has used the new tech..

The Crimp Is Automatic.

Phillip Slack and Extrusion Systems Limited exhibited Autocrimp at ITMA 1995. Autocrimp gives extruded polypropylene and automatic three dimensional helical crimp like that of wool. Autocrimp builds differential shrinkages into the fiber at the time of extrusion, resulting in a permanent crimp that can only be removed by actually destroyi..

Texturing of Yarns.

The unique yarn textures obtained in twist texturing are due to varying amplitudes and wavelengths of unmatched phases in individual filaments, as well as the migratory patterns followed by the filaments. The migratory patterns are influenced by base yarn characteristics and their interactions with texturing conditions. Texturing conditio..

Composite Yarns by a New Technique--Part Ⅰ.

Researchers developed a technique for separating the individual filaments of continuous filament yarns. Researchers treated the yarns with a small amount of Permalose TM antistatic agent and induced electrostatic charges onto the individual filaments. The separated filaments intermingled with a drafted ribbon of fibers at the front roller..

Study about the Influence of Washing and Sizing on the Spinning Stability and Properties of Yarns.

Researchers investigated the influence of the faulty scouring of wool on the spinning stability and properties of yarns. The study evaluated problems caused by the accumulation of nonspinnable residues in the components of the spinning frame that adversely affected spinning and yarn properties.

Yarn Tensile Properties.

The frictional force between fibers determines the strength of staple yarns, which reflects the fiber surface properties and the transverse pressure in the fiber assembly. The conventional method of creating transverse forces of coherence between fibers during the spinning of staple yarn is twisting, either by rotating the output package ..

The Use of Hemp Fibre in Blends with Flax for the Production of Worsted Yarn.

The Institute of Natural Fibers in Pozan, Poland, is investigating the use of hemp fibers for the production of flax/hemp yarns. Researchers blended hackled hemp fiber with flax fiber from a bleached roving. A 30 percent hemp fiber content yielded an 84 tex yarn. Reducing the hemp content to 15 percent yielded a 75 tex yarn with improved ..
