Розробка двошарового трикотажу технічного призначення

Abstract

У роботі висвітлено особливості вироблення двошарового кулірного трикотажу технічного призначення з пружними властивостями у напрямку, перпендикулярному до площини полотна. Представлено результати досліджень його фізико-механічних характеристик, зокрема перевірено стійкість армуючого наповнення двошарового трикотажу, сформованого безпосередньо у процесі в'язання, до стискаючого зусилля.

В работе освещены особенности выработки двухслойного кулирного трикотажа технического назначения с упругими свойствами в направлении, перпендикулярном к плоскости полотна. Представлены результаты исследований его физико-механических характеристик, в частности проверено устойчивость армирующего наполнения двухслойного трикотажа, сформированного непосредственно в процессе вязания, к сжимающему усилию.

These days, a tendency of finding out of new opportunities of knitting equipment uses in production of technical knitted fabrics takes place. The production of upholstery textiles of various purposes is in progress. For seat upholstery and car interiors decoration knitted materials are widely used. They can be dual-layer (laminated foam) or three layers. There is a global practice of manufacturing of two-layer warp knitted fabrics of technical use with the elastic properties in the direction perpendicular to the fabric plane, and with the possibility of varying its thickness. However, domestic experience of production of weft-knitted technical fabrics with corresponding properties does not exist. But this trend in knitting industry is clearly promising. A structure of a two-layer technical fabric is developed, and samples are produced on a double-bed circular knitting machine of 10 gauge. As a connecting thread for the elastic properties of the fabric in the direction perpendicular to its surface, a nylon monofilament with diameter d=0,15; 0,20 mm were used. Thus for knitting of technical face as well as for knitting of technical back layers cotton-orlon yarn of linear density 25x2 tex was used. During the process of knitting special features of two-layer knitwear manufacturing of connection of separate layers by additional threads of high elasticity are detected. Parameters of the structure and physical and mechanical properties of knitted fabrics have been investigated. Reinforcing filling of two-layer knitwear stability to compressive force is studied.
