Yarn Characters under Steam Relaxation.

Research on the effect of steam relaxation on yarn propeties sampled acrylic yarns spun on Murata air jet spinning machines. Critical processing conditions were the second nozzle pressure, spinning speed, and the distance between the first nozzle and fron

Redefining the Role of Glass Fiber Tire Cord.

A presentation at Clemson University's October 1984 Tire Technology Conference addresses how Owens-Corning redefined the role of glass fiber tire cord in the early 1980s to focus on improved and more cost effective radial belts and monoply radial carcasses. Vitrex-HMI is Owens-Corning's new high modulus inorganic tire cord product specifi..

KEVLAR Aramid as a Reinforcement for Tires.

A presentation at Clemson University's October 1984 Tire Technology Conference describes the basic processing techniques relevant to the preparation or conversion of tire cords and fabrics from Kevlar yarns, including basic considerations related to cord construction selection, the twisting and weaving processes, and the combined operatio..

An Overview of Polyester in Tires.

A presentation at Clemson University's October 1984 Tire Technology Conference discussed the role of polyester in the United States tire industry as well as basic laboratory tests for assessing tire cord properties. In the 1970s, Celanese introduced a ran

Tire Cord Yarns: Measuring System for Quality Controls and Determining Running Lengths.

Temco's Twistor Evaluation System continuously measures the quality of tire cord during production and triggers the doffing operation when a predetermined running length has been attained. The typical installation comprises eight Twistor systems connected to a central communications box that is interfaced with a personal computer. Rollers..

Benchmarking for Staple Carpet Yarns.

Effective management requires the ability to set baselines, benchmarks, and key operating data for staple carpet yarn production. Manufacturing cost estimates include itemization of all plant processing with regard to personnel, benefits, utilities, fuel,

Advance Look at KAE International: Sweater and Sweater-Type Machinery.

Although the sweater market performed poorly in 1995, machinery manufacturers remain optimistic for 1996. According to manufacturers, selling machines is not a problem, but getting paid is. Financing remains a major challenge. To remain competitive in the sweater market, apparel manufacturers continue to diversify into niche markets. At t..

High-Speed Machines for Tyre Cord and Industrial yarns.

Rieter Chemical Fiber Systems manufactures two types of draw winding machines for the tire cord and industrial yarn industry. Riedraw is an extremely flexible machine due to its modular design. Its main applications are for such end products as air bags, safety belts, and tarpaulins. The heavy duty Riecord machine uses yarn in the 1,100 a..

BCF Yarns: Package to Tufter.

An introduction to bulk continuous filament (BCF) yarns from Clemson University's 1987 conference on carpet manufacturing technology outlines their development, including historical trends and such driving forces as lower processing costs and improved uni

기후 손상을 받은 면의 새로운 처리법(제4보) 직물속의 처리된 면사

수확 전에 손상을 받은 실은 천연 왁스에 영향을 주어 방적공정에서 문제를 발생시킨다. 저자들은 이 문제를 윤활제나 유연제로 처리하여 해결하였다. 이 처리에 의해서 방적사의 인장강도가 미처리 섬유로 만들어진 방적사의 인장강도보다 떨어지는 것이 밝혀졌다. 본보에서는 강도저하의 원인이 방적사 속에 존재하는 윤활제에 의한 것으로 생각하고, 이 사실을 입..
