Evaluating the Physical and Fabric Hand Characteristics of Lyocell Fabrics Made with Different Wood Pulps

Abstract

Four different kinds of wood pulp are used to make lyocell fabric and its intermediate products, and each is evaluated in terms of its physical characteristics and fabric hand values measured with the Kawabata Evaluation System for Fabrics. The rank orders of fiber, yarn, and fabric characteristics as a whole suggest that H4 pulp is ranked highest for its physical characteristics, thus producing textile intermediates with higher strength and dimensional stability than the other pulp types. Comparing such physical results with the KES-FB rank orders, it appears that high strength and stability along with high elongation and crimp factors are less significant for characterizing fabrics with higher hand values. For lyocell fabrics made from yarns with higher CV%, the results are more favorable for increasing the hand values of numeri, fukurami, sofutosa, and shari characteristics, and such fabric hand as a total is an important requirement for women’s suit fabrics.

Recycling of Superbase-Based Ionic Liquid Solvents for the Production of Textile-Grade Regenerated Cellulose Fibers in the Lyocell Process

“…Cold mercerization (NaOH 20⁰ Bé) improved the dye uptake (Goswami et al 2011). The cellulase enzyme wash cleaned the fabric surface (Morgado et al 2000;Carrillo et al 2003). Finally, the fabric was dried and transported to the printing mill.…”

Limitations of Cellulose Dissolution and Fiber Spinning in the Lyocell Process Using [mTBDH][OAc] and [DBNH][OAc] Solvents

“…First, a resin finishing mixture (resin + low density polyethylene resin (LDPE) + MicroSilicone + wetting agent, no acid) improved wrinkle recovery (Jaturapiree et al 2011). A mechanical Pentek finishing gave a soft touch to the fabric, and finally, the sanforizing process reduced the shrinkage of the fabric (Ahn et al 2005).…”

Development of polyester-based bamboo charcoal and lyocell-blended union fabrics for healthcare and hygienic textiles

“…difference ÁT, under steady state conditions, and when heat transfer is dependent only on the temperature gradient [10][11][12][13]. Thermal conductivity = heat flow rate  distance/(area  temperature difference)…”

“…Thermal conductivity (K) is an intensive property of the material that indicates its ability to conduct heat. It is defined as the quantity of heat, Q, transmitted through a thickness, L, in a direction normal to a surface of area A, due to temperature difference ÁT, under steady state conditions, and when heat transfer is dependent only on the temperature gradient [10][11][12][13]. Thermal conductivity = heat flow rate  distance/(area  temperature difference)…”

“…The advantages of lyocell include more softness, gentle to the skin, high absorbency, excellent water management property, cool and dry to touch, strong retardation to bacterial growth, and excellent wet strength. Abu-Rous et al made an effort to explain the functional and wellness properties of lyocell textiles using the nano-and porous structures of lyocell which is radically different from the other known cellulosics [9,10].…”
