This study aims at evaluating the properties of cotton fabric after nanofinishing using zinc oxide and silicon dioxide nanoparticles along with dimethylol dihydroxyethylene urea (DMDHEU).

DMDHEU recipes was optimized by Box-Behnken Design before using it with nanoparticles. These nanoparticles were synthesized by sol gel technique and applied to the fabric by pad-dry-cure method. The treated samples were evaluated for functional properties such as self-cleaning, antibacterial and ultraviolet (UV) protection properties.

Due to the use of DMDHEU, crease recovery property was obtained. The results showed good antibacterial property against S-aureus (gram positive) bacteria and E-coli (gram negative). UV protection property of combined nano-finished samples showed good results, as they showed very low transmission of UV-irradiation when exposed to UV-rays compared to single nanoparticle finished samples. Self-cleaning property of finished cotton was found to be good even after five washing cycles.

In this study, nanofinishing of cotton fabric with zinc oxide and silicon dioxide nanoparticles along with DMDHEU was studied to achieve promising functional properties with long durability of nanofinishing not studied earlier.

The purpose of this paper is to show how to remove some dyestuffs, as pollutants, from their aqueous solutions.

To achieve the goal, a water soluble hyperbranched poly (ester‐amide) (HBP) was synthesised using the melt polycondensation method by the reaction of maleic anhydride (MA) and diisopropanol amine (DIPA) at 140°C at a molar ratio of 1:1.3 MA: DIPA, respectively. This HBP was incorporated in the preparation of an effective microcrystalline cellulose (MCC)/dimethyloldihydroxyethylene urea (DMDHEU)/HBP adduct by crosslinking HBP with DMDHEU in presence of MCC. Furthermore, the prepared adduct was characterised by investigation its infra red and then utilised in the removal of three anionic dyestuffs from aqueous solutions, namely Irgalan Blau 3GL (an acid dye), SIRIUS Blau S‐BRR (a direct dye) and Levafix Brill Orange P‐GR (a hydrolysed reactive dye).

The results obtained revealed that the optimum conditions for preparing MCC/DMDHEU/HBP adduct are [HBP], 90 g/l; [DMDHEU], 200 g/l; LR, 1/3.3; [NC₄LH], 20 g/l; a time of 30 min and a temperature of 160°C. Moreover, the results also showed that the extent of removal of such dyestuffs from their aqueous solutions by the prepared adduct follows the order: reactive dye>acid dye>direct dye, it is more pronounced at lower than at higher pH values and the removal of each dye by that adduct follows a first‐order reaction.

Other substrates such as chitosan can be used to prepare more effective adducts.

Hyperbranched polymers can be used effectively to prepare ion exchangers capable of removing the pollutants of dyestuffs from their aqueous solutions.

The aforementioned prepared HBP is a novel hyperbranched polymer and could be applied in the removal of many other pollutants.

The inclusion of softeners (20 g/l), namely, Siligen VN (silicon based), Basosoft SWK (cationic), or Leomin NI (nonionic), in a dimethyloldihydroxy ethylene urea (DMDHEU, 50 g/l) finishing formulation of 65/35 cotton/polyester blended fabric, enhances the resiliency of the fabric, which is expressed as the dry wrinkle recovery angle (WRA). The fabric acquires the ability to keep a rose oil fragrance upon storage up to 3 months. Improving the WRA and acquiring the ability to keep the fragrance can be descendingly arranged as follows: Siligen VN>Basosoft SWK>Leomin NI. Increasing the Siligen VN concentration (0-30 g/l) in the finishing formulation is accompanied by a small increase in the WRA, and a noticeable enhancement in the ability to keep the rose oil fragrance upon storage. By increasing the rose oil concentration (100-300 g/l) in a perfumed bath of cross-linked/Siligen VN, the softened fabric is accompanied by a slight drop in the WRA, and a decreasing ability to keep the fragrance up to 3 months.

However, the extent of the fragrance is higher at higher rose oil concentrations, regardless of the storage time. The ability of the fabric to keep the fragrance can be attributed to solubilization and/or encapsulation of the perfume in the oleophilic segments of the softener, and its slow release with time, so that the smell can be sensed. This ability decreases after increasing the storage time up to 3 months, and depending on the type of perfume oil used, is descendingly arranged as follows: jasmine oil > rose oil > sandal oil.

Optimal conditions for condensation of equimolar ratios of stearic acid (St) and polyethylene glycol (PEG) 400, i.e. 180°C, 8hrs and H₂SO₄, 4g/kg (reactants mixture), were utilized to condensate the equimolar ratio of stearic (St), palmitic (Pa) or myristic (My) acid with PEG 300, 400, 600, 2000 or 6000. Each of the fifteen condensates was formed by total conversion (83.5 to 84.1 %). Monoester–diester ratios of the condensates ranged from 4:1 to 49:1. FT – IR spectroscopy and hydrophilic lipohilic balances (HLB) of the condensates were also examined. The condensates had softening and hydrophilic properties of cotton fabric with no yellowing at concentrations of 30 and 50g/l in the presence or absence of DMDHEU (50g/l). The presence of DMDHEU improved the fabric resiliency.

However, the softening and hydrophilic properties of the fabric were inferior in the presence of DMDHEU rather than the absence. In comparison with a commercial softener, PEG 2000- or 6000-based condensates were higher in fabric wettability and pliability but lower in smoothness. Regarding CRA, only My-2000 was comparable to that of the commercial softener in terms of effect.

Cellulosic fabric and plain weave are the most commonly used material in home textiles. The poor wrinkling, dimensional stability and pilling are some of the problems faced during usage. The textile industries apply resin finish to improve these characteristics. The purpose of this study is to improve pilling resistance, dimensional stability and smoothness appearance (SA) of rayon and rayon/cotton plain fabrics using different concentrations of dimethyloldihydroxyethylene urea (DMDHEU) and acrylic copolymer. The finish was fixed using two different fixation methods.

Three concentrations, 40, 100 and 150 g/l of Arkofix NF (DMDHE based) and Appretan N9211 (acrylic copolymer), were taken. The finish was applied at normal and shock cure. The effects of finish on pilling resistance, dimensional stability, smoothness, tear strength, light fastness, Berger whiteness and yellowness index of plain fabrics were investigated.

The changes in the characteristics of the finished fabrics were compared with unfinished fabrics. This study revealed that at 40 g/l of Arkofix NF and Appretan N9211 using a normal cure would improve the pilling resistance, dimensional stability and SA of the plain fabrics. Whereas, there was no adverse effect observed on tear strength, light fastness, Berger whiteness and yellowness index of plain fabrics at these conditions.

Unlike the previous studies, this paper proposed the single finish formulation where the functional characteristics of the plain rayon and rayon cotton fabrics meet the general requirement of a customer.

This study aims to explore the incorporation of the authors previously prepared chitosan nanoparticles (CNPs) of size around 60-100 nm in the cross-linking formulation of viscose fabrics to see CNPs impact in terms of imparting multi-functional characteristics such as tensile strength, dry wrinkle recovery angles and antibacterial properties.

CNPs of size around 60-100 nm were incorporated in cross-linking formulations for viscose fabrics, including different concentrations of glutaraldehyde as a non-formaldehyde cross-linking agent and magnesium chloride hexahydrate as a catalyst. The formulations were applied at different curing times and temperatures in 100 mL distilled water, giving rise to a wet pickup of ca. 85 per cent. The fabrics were dried for 3 min at 85°C and cured at specified temperatures for fixed time intervals in thermo fixing oven according to the traditional pad-dry-cure method.

The above eco-friendly method for finished viscose fabrics was found to obtain high dry wrinkle recovery angle and maintain the tensile strength of the finished fabric within the acceptable range, as well as antibacterial properties against Escherichia coli and Staphylococcus aureus as a gram-negative and gram-positive bacteria, respectively. Both, scanning electron microscope and nitrogen percent on the finished fabric confirm the penetration of CNPs inside the fabric structure. Finally, viscose fabrics pageant antibacterial activity against gram-positive and gram-negative bacteria assessed even after 20 washing cycle.

CNPs with its flourishing effect with respect to cationic nature, biodegradability, reactivity, higher surface area and antimicrobial activity; in addition to glutaraldehyde as non-formaldehyde finishing agent can be used as multi-functional agents for viscose fabrics instead of DMDHEU, polyacrylate and monomeric composites as hazardous materials.

CNPs as cationic biopolymers were expected to impart multi-functional properties to viscose fabrics especially with obtaining reasonable dry wrinkle recovery angle and tensile strength in addition to antibacterial properties.

The novelty addressed here is undertaken with a view to impart easy care characteristics and antibacterial activities onto viscose fabrics using CNPs as antimicrobial agent and glutaraldehyde as non-formaldehyde durable press finishes to-replace the traditional formaldehyde-based resins. Besides, to the authors’ knowledge, there is no published work so far using the above cross-linking formulation written above.

The purpose of this study was to overcome discomfort associated with it, a resin finish was applied in conjunction with hydrophilic polyurethane.

The process variables included concentrations of polyurethane and resin finishes, and pH under central composite design (CCD). The fabric specimens were assessed for crease recovery angle (CRA), tensile strength and moisture management properties.

Some models were developed for prediction of CRA and overall moisture management capability (OMMC) of treated fabric. It was observed that polyurethane concentration showed a parabolic relationship with CRA and a direct relationship with OMMC, whereas resin concentration showed a parabolic relationship with CRA and an inverse relationship with OMMC. Increase in pH from acidic to alkaline resulted in a decrease in CRA but an increase in OMMC. The untreated specimen had the highest tensile strength, whereas the specimen treated with polyurethane showed the least tensile strength loss, and the one treated with resin showed the highest loss in tensile strength.

As the polyurethane-based finish is soft and hydrophilic, so it was expected that it would overcome the uncomfortable feature of durable press finish, and with its flexibility, the strength losses might reduce.

This is the first report about the investigation of effects of increasing flexibility of the cross-link by incorporating polyurethane compounds into a typical dimethylol dihydroxy ethylene urea durable press resin formulation.

The purpose of this paper is to analyze the effects of chitosan treatments on exerted pressures of nylon 6.6/elastane pressure garments in three different knit structures using wireless pressure sensors for an accurate and a precise scar management for future designs.

Pressure garments designed in different structures consist of 70/30 and 75/25 nylon 6.6/elastane were treated with chitosan and the exerted pressures were analyzed using wireless pressure sensors including ultra-thin and flexible printed circuit sensors in comparison with untreated control samples. Antimicrobial activities and washing tests were also evaluated.

It is found that chitosan treatments have a significant effect on final pressures. Exerted pressures increased significantly for all samples after chitosan treatments. Higher pressures were measured for weft knit structured designs while lower pressures were recorded for powernet structured garments. It is found that the elasticity showed a small significant decrease and it has attributed due to a small significant shrinkage during processes. The mean scores of pressures were found in the acceptable medical range which will continue to help hypertrophic scar management for future designs. The exerted pressures of the fabrics remained constant after five washes and showed a small significant decrease after 10 and 50 washes which will provide a long period of compression. Permanent antimicrobial effectiveness has gained at around 90 percent after five washes and 50 percent after 50 washes. A small significant increase was observed for stiffness (CD, MD) after ten washes.

Chitosan treatments impact exerted pressures of pressure garments significantly. It is a reference to evaluate pressure functions of pressure garments using wireless pressure sensors while imparting antimicrobial activity.

The purpose of this paper is to assess the possibility of cross-linking silk fabric using citric acid (CA) as the cross-linking agent and nano-TiO2 (NTO) particles as a catalyst at low temperature and under UV irradiation. This paper also assesses the possibility of treated samples with suitable combinations of CA and NTO to impart multiple functional properties such as self-cleaning and antimicrobial properties.

In this research, ß-cyclodextrin (ß-CD) grafted onto silk fabric using CA as a crosslinking agent and NTO particles as a catalyst through a pad-dry-cure technique and with UVA irradiation. The effects of different concentrations of CA, ß-CD and NTO particles on some properties of the treated samples are evaluated, and the optimum finishing conditions are obtained. The author also investigated the washing durability of the modified product after ten times of washing.

The results showed that CA plays the role of a linking agent through an esterification reaction with the hydroxyl groups of both ß-CD and silk fabrics and improves the durability of materials on the textile surface. Also, the silk fabrics treated with CA only were found to have excellent photocatalytic properties and better antibacterial activity than the control sample and the fabrics treated with a mixture of ß-CD/CA.

This study was conducted to achieve multiple functions such as antibacterial and photocatalytic activities, good dry crease recovery angle and wet crease recovery angle behavior without a significant adverse effect on the Yellowness index and tensile properties for treated silk fabrics.

The purpose of this paper is to study the effect of matter, laundering types, special treatments and their succession applied during the manufacturing process of garment washing on the cloth shade.

Denim garment manufacturers are interested in finishing cloth to characterizes the aging look of the cloth. The effect of matter, laundering, special treatments and their succession were studied. The treatments have been done on manufactured trousers. One rigorous statistical study is achieved to validate the experimental results.

The mixed washing is the most degrading for the shade of cloth and appearance of the garment's surface and the succession of special treatments of finishing is demanded to have an increasing whiteness. The finishing resin‐treatment realized before any washing process (stone washing or mixed washing) provokes a slight increase of garment colour resistance.

Information from this study will aid manufacturers of garment washing jeans in selecting the finishing method that suits their marketing/manufacturing plants.
