Effect of Raw Material on Changes in the Weft Setting of Fabric

Adomaitienė A., Kumpikaitė E.

Fibres & Textiles in Eastern Europe

2009

Vol. 17, no. 5 (76)

49--51

This article analyses the dependence of changes in the weft setting of fabric on the integrated fabric structure factor j, for woven fabrics of different raw materials. Similar research of the above changes after taking a fabric out of a loom and of the “stabilization in time” a fabric structure has not been conducted so far, despite the importance of trying to precisely evaluate the fabric structure at different stages of its manufacture. Five fabrics of different raw materials were analyzed with respect to changes in their weft setting after taking the fabric out of loom and the ”stabilization in time” of its structure. It was found that the above changes are regular in comparison with fabrics of different raw material.

Artykuł przedstawia analizę zależności pomiędzy zmianami gęstości wątkowej tkaniny a zintegrowanym współczynnikiem strukturalnym tkaniny φ dla tkanin wykonanych z różnych surowców. Badania porównawcze tych zależności prowadzone były dla tkanin bezpośrednio po zdjęciu ich z krosna oraz po stabilizacji tkaniny w czasie. Próbowano określić precyzyjnie strukturę tkaniny w różnych stadiach jej produkcji. Badano 5 tkanin wykonanych z różnych surowców biorąc pod uwagę zmiany gęstości wątkowej po zdjęciu tkaniny z krosna i jej stabilizacji. Stwierdzono wyraźne różnice przy porównaniu tkanin wyprodukowanych z różnych surowców.

Evaluation of the weavability of sized cotton warps

Maatoug S., Ladhari N., Sakli F.

Autex Research Journal

2007

Vol. 7, no. 4

239--244

In weaving, a warp must withstand repeated stretching, caused by shedding and beat-up. It is also subjected to abrasion, which is mainly due to shedding and reed motion. The yarns are therefore sized. Two important reasons for applying sizes to spun warp yarns are to protect them breaking during weaving and to decrease their hairyness so that the tendency for adjacent warp yarns to entangle will be reduced. In this work, we investigated the weaving performance and physical properties of cotton yarn sized at high pressure squeezing. We studied the size penetration, film properties, and the yarn packing density in order to explain the performance of sized yarn.

Effect of sizing on weavability of Dref yarns

Behera B. K., Joshi V. K.

Autex Research Journal

2006

Vol. 6, no. 3

142--147

The optimum-size add-on for corespun Dref yarns and 100% cotton Dref yarns was studied, and was found to be approximately 15%. A rich size recipe consisting of acrylic at high add-on further improves the weavability, although it fails to bring the weaving potential to a par with that of ring- and rotor-yarns sized with normal modified starch at low add-on.
