Title: Effect of Processing Parameters on Incidence of Slubs in Polyester-Viscose Yarn and Fabric Authors: Sharma, I C; Gupta, Narender; Gupta, Dinesh; Vaid, Kallash; Goyal, Surender Kumar Abstract: The effect of blend percentage, yarn count and different processing parameters, viz. spindle speed, break draft, spinning draft and apron spacer size, on the incidence of slubs in polyester-viscose blend yarn and at fabric stage (in weft direction) was studied. With increase in the polyester content in the polyester-viscose blend the number of slubs decreased; increase in spindle speed, break draft and finer count resulted in increase in the number of slubs. Minimum number of slubs occurred at a particular spinning draft and apron spacer size; and if these were increased or decreased, the frequency of slubs increased. However, there was no significant difference in the number of slubs in the fabric state. Page(s): 32-34

Title: Antimony Compounds as Flame Retardants for Cotton Textiles Authors: Jain, J P; Saxena, N K; Saxena, (Km) Abha; Gupta, D R Abstract: To render cotton fabrics fire retardant, three chemical formulations, viz. solvent suspension, emulsion, and titanium-antimony combinations containing some chlorinated compounds, were studied. The treated fabrics were tested for fire performance, tensile strength and effects of laundering. The results show that these treatments could be used to reduce fire hazards in tents, pandals, etc; such treated fabrics may also be useful for military purposes. Page(s): 30-31

Determination of Diameter of Loose Wool by Air Flow Method

Title: Determination of Diameter of Loose Wool by Air Flow Method Authors: Chopra, S K Abstract: The diameter of loose wool was determined using an air flow apparatus and the results were compared with those obtained with a projection microscope. A linear relation was found between the average diameter and the height of air column. The effect of variation of diameter within a sample on the air flow value was also studied. Page(s): 28-29

Effect of Weft Rewinding Tension on Fabric Properties

Fri, 01 Mar 1985 00:00:00 GMT

Title: Effect of Weft Rewinding Tension on Fabric Properties Authors: Sharma, I C; Bhardwaj, S K; Gupta, Narender Kumar; Sharma, Ayush Abstract: The effect of different weft rewinding tensions of texturized polyester filament yarns of 150 and 150/2 deniers on fabric properties, such as tearing strength, breaking strength and dye uptake, has been studied. At both deniers there was no significant effect on the tearing strength and tensile strength in weft direction. The elongation at break decreased with increase in tension in both the cases. The dye uptake, measured in terms of optical density, decreased initially with increase in tension but with further increase in tension, increased in both the cases. Page(s): 26-27
