Study On The Technology And The Properties Of The Tri-component Sirofil Composite Yarn

First, the paper studies the influence of the single-factor--the Pre-tension of the silk, the space between the silk and the roving, the Pre-tension of the polyester filament, the twist of the Sirofil composite yarn on the properties of yarn. The single-factor of these parameters produces corresponding influence on the performances of yarn, such as breaking strength, breaking elongation percentage, hairiness index, yarn unevenness, slipping resistance, etc.Second, by an orthogonal experiment and the analysis of variance, the paper studies the influence of the comprehensive factors— the Pre-tension of the silk, the space between the silk and the roving, the Pre-tension of the polyester filament, the twist of the Sirofil composite yarn on the properties of yarn. then a optimum technical parameters of the Sirofil composite yarn was got by optimum experiment . that is: Pre-tension of silk 15cN, the space 8cm, the Pre-tension of polyester filament 25 cN, the twist of the composite yarn, 73.6tpcm.By comparing the properties of Tri-component Sirofil Composite yarn with the ring yarn, the polyester filament /cotton core-spun yarn and the silk/cotton Sirofil yarn, the relation between Structures and Properties of Tri-component Sirofil composite yarn has been studied.Base on the present Sirofil spinning theoretics, the structure of the...
