“…Moreover, porosity also influenced other functional properties. 21,22 Bending behavior was important for stitchability as well as drape when something was kept inside the bag. 23 A low wetting property was required for most of the carry bags.…”

A thermally bonded biodegradable fabric has been developed using mesta and polylactic acid fibers. The central composite rotatable design has been adapted to understand the effects of the independent variables, that is polylactic acid content, roller temperature and roller pressure on useful functional properties such as bursting strength, bending load, tensile stress relaxation, tensile creep, rate of absorption, absorption capacity, porosity, abrasion resistance, and surface friction. Considering the linear, quadratic, and two-way interactive effects of independent variables, the second-order polynomial has been suggested for each property which proves good association except for absorption capacity and abrasion resistance. The effect of independent parameters has been studied and optimized from contour diagrams. The optimized process parameters for 140 g/m2 fabric are polylactic acid content 30%, mesta content 70%, roller temperature 170°C, and roller pressure 150 N/cm2, which can be used successfully as a shopping bag. The shopping bag was prepared from developed fabric. Its performance test shows no deformation for up to 14 days in the hanging test, resistance up to 10 wetting-drying cycles proves reusability, it sustains up to four drops, and has a slight strength loss in 30 days of atmospheric exposure.

“…The measurement of the bending load was tested in the computerized bending tester developed by ICAR-NIRJAFT, Kolkata. 18,19 A modified hanging loop technique was adopted to test the samples in this instrument. A vertical ring loop of maximum diameter was formed from a rectangular fabric strip (40 Â 5) cm.…”

Mattress plays an important role in the quality of human sleep, warp-knitted spacer fabric (WKSF) is a rather important mattress material, this paper explored the indentation state of WKSFs of 20 mm thickness and 0.12, 0.15, 0.18, and 0.25 mm spacer filaments under the action of curved surface pressure by using spherical compression tests and finite element simulations, with the combination of three-dimensional and non-uniform pressure characteristics exerted on the mattress by the human body when lying down. Tests and simulations analysis would be shown in four aspects: firstly, when the spherical indenter acts on the WKSFs, the compressive stress, Indentation Force Deflection (IFD) and support factor (SF) of the WKSFs increase as the spacer filament fineness increases; secondly, the compression depth of WKSFs should be controlled within 40% when used as mattresses to obtain good compression comfort; thirdly, A warp-knitted spacer fabric with a 0.25 mm spacer filament fineness provides both comfort and pressure resistance and better meets the needs of most people for a spacer fabric for mattresses.

“…Table shows that the FPL printing without binder exhibited a smaller bending rigidity and hysteresis than that of conventional printing. This indicated that a smaller resistance to bending and energy dissipated by the former at time of shear loading than the latter, and inevitably lead to better hand feel . The color strength, washing, and rubbing fastness of the printings were also investigated.…”

The recognized disadvantages of pigment printing are the stiff hand feel owing to the large particle size of the binder and pigments and the crosslinked binder introducing rigidity. In the current study, fluorescent pigment latex (FPL) was prepared via mini-emulsion polymerization and further applied on cotton fabric printing in the absence of binder. The mini-emulsions were prepared by dispersing the fluorescein in the monomers methyl methacrylate (MMA) and butyl acrylate (BA) with DNS-86 as emulsifier, hexadecane as co-emulsifier, and ammonium persulfate as initiator. The Fourier-transform infrared-attenuated total refraction, transmission electron microscopy, differential scanning calorimetry, and thermogravimetric analysis showed that the fluorescein was successfully encapsulated into P(MMA-co-BA) and the polymer content was 91.22%. The surface morphology study revealed that compact and smooth film was formed onto the surface of FPL printings, which resulted in better hand feel and rubbing fastness as compared to the conventional printings with a large amount of binder.
