Jute spun yarn

Catalog	ACMA00031142
Description	Jute is an attractive and versatile fiber with an aesthetic appeal. The Golden Fiber has gained immense popularity around the globe because of its bio-degradable character. It is a natural vegetable fiber which merges with soil and does not emit toxic fumes or residue on combustion.
Application	Luxurious range of Jute home decor products are available to suit different life styles.
Feature	100% bio-degradable recyclable and thus environment friendly Natural fiber with golden & silky shine The second most important and widely cultivated vegetable fiber after cotton High tensile strength with low extensibility this helps to make best quality industrial yarn and fabric for packaging Very versatile natural fibers that has been used in raw materials for packaging, textiles, non-textile, and agricultural sectors Jute stem has very high volume of cellulose that can procured within 4-6 months, and hence it also can save the forest and meet wood requirement

Case Study

Compression Molding of Jute Yarn/PLA Unidirectional Composites

Memon, Anin, et al. Energy Procedia, 2013, 34, 830-838.

Jute yarn/PLA unidirectional composites were prepared by compression molding. With the increase of molding temperature, the impregnation quality and dispersion of the fiber bundles improved, so the elastic modulus achievement rate increased. However, too high a molding temperature will lead to the deterioration of jute fibers, so the optimal molding temperature for preparing jute yarn/PLA unidirectional composites is 185-195°C.
Preparation procedure of jute yarn/PLA composites
· Jute spun yarns were combined with polylactic acid (PLA) fiber for making unidirectional composites. The jute spun yarn had a fineness of about 400 tex, used as reinforcement fibers, while the PLA fibers, in tow configuration, had a fineness of about 56 tex, used as resin fiber.
· The fabrication of jute spun yarn/PLA unidirection composites involved twofold processes. Firstly, the parallel yarn was wound 20 times onto a metallic frame equipped with a spring mechanism to adjust tension due to fiber shrinkage. The yarn was then dried in an oven at 80°C for two hours before being placed in a heated mold for consolidation.
· The consolidation process included three stages - softening of matrix materials, infiltration of liquid matrix into reinforcing fibers, and solidification of the matrix to hold the fibers in place. The most crucial step was when the liquid PLA resin impregnated the jute spun yarn during molding. According to the TGA data of jute and PLA, the compression molding temperature was design at 185, 195, 205, 215, 225 and 235°C. The compression molding time was conducted with the pressure 1.33 MPa for 8 minutes.

Manufacturing and Properties of Jute Core Spun Yarn

Uddin, Md Bashar, et al. Text Leather Rev, 2022, 5, 414-429.

In core spun yarn, filaments as core material are used to provide functional properties, while natural fibers as covering materials are used to provide surface physical properties and natural appearance. In this work, jute core spun yarns containing polyester filaments of different linear densities were manufactured. Jute core spun yarns showed significantly higher strength (233.13% to 315.5%) and elongation at break (257.9% to 367%), and lower unevenness (Um%), defect values, and hairiness compared to 100% jute yarn.
Preparation Procedure of Jute Core Spun Yarn
· After immersing the jute fiber in a 20% emulsion for 48 hours, it underwent processing through a jute breaker, finisher card, and three drawing machines in succession. Subsequently, the third drawn jute sliver with a linear density of 4 gm/yd (43600 dtex) was drafted on the modified jute flyer-spinning machine to create yarn samples.
· To assess how the linear density of the core filament affects the properties of core-spun jute yarns, five different yarn samples weighing 11 lbs/spyndle (3789.5 dtex) were produced, with one sample consisting of 100% jute yarn.
· The spinning draft and filament pre-tension were adjusted to achieve the same yarn linear density with varying filament linear densities. The flyer speed remained at 3500 RPM and the twist factor (K) was maintained at 12, while other process parameters were consistent throughout the yarn production process.
