In this study, crease resistance performance of citric acid treated cotton fabrics was studied. The fabric was treated with citric acid for giving crease resistance behavior and the performance of finishing was tested by measuring crease recovery angle of the fabrics. Bending length and tearing strength of the fabrics were also carried out.

Dec 2022

Cotton is an affordable and durable option for clothing. However, cotton garments tend to wrinkle easily. Therefore, cotton fabrics were studied to improve their wrinkle resistance properties. In this work, curcumin was mixed in an aqueous solution of citric acid and its catalyst and applied to cotton fabric using pad-dry-cure process for both the dyeing and finishing properties. Aloe vera extract and chitosan were used to compare for the reaction of their functional groups with carboxyl groups of citric acid on cotton fabrics. The mixture of curcumin and citric acid solution showed anti-wrinkle properties on the treated cotton. There were no functional groups of curcumin detected on the FTIR spectrum of the fabric. Furthermore, acetyl group of chitosan and methyl in acetyl group of aloe vera extract were found on the spectra of the fabrics treated with each compound. It was also found that the treated fabric showed good UV protection properties and good antibacterial gram-positive properties. This fabric has physical potential to be used for healthcare, hygiene and medical textile products.

Effect of construction on some mechanical properties of non-finished and finished cotton fabrics

December 2000

The analysis of fabrics of different woven constructions made of the same count of yarn indicates different wrinkle recovery and other mechanical properties before and after wrinkle resistant treatment. For the plain weave fabrics, parameters of the warp threads and weft threads can influence the effect of wrinkle resistance finishing. When the parameters of warp threads are similar as that of ... [Show full abstract] the weft threads, the even-structure can be obtained. Therefore, the best wrinkle recovery angle can be obtained. With the increasing of warp threads and weft threads, the strength of non-finished and finished fabrics can be increased. When the warp threads are similar as the weft threads, high strength retain can also be obtained.

The effect of various chemical/wet processing on fabric appearance and durability

January 1995

The effect of processing treatments of grey and finished woven plain fabrics on appearance has been analysed in terms of crease recovery, drapability and pilling propensity, and on durability, in terms of tensile strength, tearing strength and abrasion resistance. The influence of yarn and fabric parameters such as yarn count, sett, thickness and weight (g/m"SUP 2" ) on the appearance and ... [Show full abstract] durability of the fabrics was considered. Results showed that fabric appearance and durability are affected by various processing treatments. Better drape, poor crease recovery, higher tensile strength and abrasion resistance and lower tearing strength were obtained.

Tearing strength of cotton fabrics in relation to certain process and loom parameters

Tearing strength of cotton fabrics made of ring- as well as compact-spun weft yarns has been studied in relation to certain process and loom parameters. It is observed that the fabrics made of compact-spun weft yarns are more tear resistant. The tearing strength further improves particularly in the weft-way direction with the increase in weft yarn linear density and weft tex twist factor. There ... [Show full abstract] is an initial increase in strength followed by a decrease as the number of picks/inch is increased in the cotton fabrics made of compact-spun yarns. However, for the fabrics made of ring yarns, it shows a general decreasing trend. The 2/2 designs are found to be superior in warp-way but inferior in weft-way directions. The fabrics woven on air-jet looms show lower tearing strength than those woven on projectile looms. The mechanical finish as well as the variation in shed opening do not affect the tearing strength of cotton fabrics produced from compact-spun weft yarns.

Effect of wrinkle resistance finish on cotton fabric properties

June 2009 · Indian Journal of Fibre & Textile Research

The effect of crease resistant finish on wrinkle recovery, breaking strength, tearing strength and pilling performance of 100 % cotton plain fabrics has been studied. Desizing, scouring and crease resistant finishing have been performed on the fabric and their effects are observed. A statistical analysis using a paired t-test with the significance level of �= 0.05 has been performed to determine ... [Show full abstract] if a statistically significant difference exists among fabric properties using the above processes. It is observed that no statistically significant change occurs on the fabric properties from scouring. However, the changes due to crease resistant finish are found to be statistically significant. In addition, the wrinkle recovery angle increases approximately 50%, and breaking strength and tear strength decrease about 25%, and pilling performance reduces 59% after the crease resistant finishing.
