Effect of Hydrophobic Plant Extract on the Physicochemical Properties of a Transparent Fabric Softener

This article investigates the effect of hydrophobic supercritical CO₂ raspberry seed extracts on the physicochemical and functional properties of a modern, transparent fabric softener. The addition of a hydrophobic extract to a transparent softener formulation increased the turbidity and dynamic viscosity of the product compared to the reference formulation (with no added extract). In addition, fabric rinsed in a bath containing the transparent fabric softener enriched with the hydrophobic extract was characterized by a higher degree of softness and slightly lower values of fabric rewettability (two parameters determining the usable properties of this type products) in relation to the values determined for a fabric exposed to the rinsing process in an aqueous solution of the transparent fabric softener without added extract. The results obtained in the assessment of physicochemical properties point to the modification of the structure of fabric softener resulting from the growth of surfactant aggregates due to solubilization of the hydrophobic extract. As a consequence, the deposit—an adsorption layer of surfactants (responsible for key characteristics relevant to the performance of this type of products) remaining on the fabric after the rinsing process—is modified.

Interaction between the Surface Properties of the Textiles and the Deposition of Cationic Softener

In this study we categorised the surface properties of different knitted fabrics by their electro-kinetic behaviour and liquid up-take phenomena of the knitted textiles in order to understand the interaction of the surface properties of the textiles with cationic softener deposition. The electro-kinetic and liquid uptake properties of textiles were measured by their zeta-potential and liquid absorption ability. We also examined the influence of fabric softener on the surface characteristics of the textiles. We used solvent extraction followed by cationic titration to determine the cationic softener level present on the textiles. The major finding of this study was the different behaviour of individual loads and mixed loads in terms of cationic pick up from the rinse cycle softener. Fibre type plays the most critical role in determining the zeta potential of the fibre, filtration efficiency and water retaining capability of the fabrics, which in turn play the most important role in softener deposition on the textile. The charge on the textile surface is negative; this plays a key role in the deposition of the cationic softener in both kinds of loading conditions. Capillary diffusion could be a key parameter only in the individual load condition. It was found that there is a significant reduction in the liquid adsorption weight when fabrics are treated with levels of softener that are much higher than those associated with normal consumer use. As soon as the fabric comes into contact with the liquid, the fabric softener molecules transfer from the fabric to the liquid and reduce the surface energy of the liquid. This results in an increase in the wetting weight of the fabric.     

Application of polyurethane/citric acid/silicone softener composite on cotton/polyester knitted fabric producing durable soft and smooth surface

Application of softeners on fabrics can usually increase the fabric pilling tendency and it is difficult to obtain a soft handle fabric without pilling during wearing. This research was conducted to use various chemicals to reduce pilling with reasonable softness on the cotton/polyester knitted fabric. Diverse composites of the water‐based polyurethane resin (PU), citric acid (CA) as a crosslinking agent and silicone‐based softener were selected and applied on the fabric through conventional pad‐dry‐cure method. The characteristics of the treated fabrics including pilling rate, pilling density, water droplet adsorption time, bending length, crease recovery angle, tensile strength, and water contact angle were examined and reported. Application of the polyurethane resin along with citric acid reduced the fabric pilling. However, co‐application of resin, CA, and softener improved the fabric crease recovery angle, bending length, and water droplet adsorption time. The preferred formulation was 20 g L^?1 CA, 25 g L^?1PU resin, and 20 g L^?1 silicone softener. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012

Investigation on decontamination mechanism of moisture-wicking fabrics during home laundry

Moisture-wicking clothes are widely consumed in various leisure or sports activities due to their function of moisture absorption and perspiration, which can provide consumers with a good comfortable experience. In this investigation, the stain removal performance of moisture-wicking fabric was investigated, especially the influence of surfactants and hydrophilic finishing agents on its decontamination ability. The results show that moisture-wicking fabric has better decontamination performance than ordinary polyester fabric. The binding force between stains and fibers is calculated by density functional theory (DFT). Compared with ordinary polyester fabric, the binding energy between moisture-wicking fabric and sebum is lower, resulting in stain is more easily to be removed during washing. Different surfactants have a great influence on the decontamination of fabrics, among which the nonionic surfactants with longer carbon chains have the best decontamination performance. Moreover, after finishing with hydrophilic silicone agent, the hydrophilicity of the fabric is significantly improved, and its decontamination performance is also improved. However, this hydrophilic silicone agent will be gradually removed in the subsequent washing process, especially after the first washing, the removal rate reached 75.70%. Therefore, hydrophilic silicone agent can be supplemented in detergent formulation to improve the stain removal performance of moisture-wicking cloths during home laundry.

Antibacterial Cotton Fabrics Coated by Biodegradable Cationic Silicone Softeners

A series of ester-containing cationic silicone softeners with different alkyl chain lengths were successfully synthesized to manufacture antibacterial cotton fabrics. The relationship between the molecular structure and the softener's mechanical and physical properties was investigated. This study demonstrated that the fabrics treated with SiQC_nCl softeners bearing short alkyl chains (n = 9, 11, and 13) showed better instantaneous hydrophilicity, close to that of a pristine cotton fabric. However, the SiQC₁₇Cl-treated fabrics with long alkyl chains showed the best softness, exceeding that achieved with the conventional finishing agent D1821. And the whiteness index of the fabrics decreased with the use of longer fabric finishing times, with the SiQC₁₅Cl-treated fabrics exhibiting the highest whiteness index. Moreover, it was also found that SiQC_nCl-treated fabrics showed higher antibacterial activity against Staphylococcus aureus than Escherichia coli, with the SiQC₁₃Cl-treated fabrics exhibiting the best antibacterial activity. In addition, a model depicting the antibacterial action of the prepared fabrics was illustrated. Finally, it was discovered that the synthesized ester-containing cationic silicone softener showed better primary biodegradability than D1821 and DC-5700, exceeding 80% after a 120-h degradation.
