“…Nevertheless, silk anti-crease finishing with BTCA has the disadvantages of significant strength loss and high cost. Other common formaldehyde-free silk anti-wrinkle agents, such as epoxides [10,11], siloxanes [12], glyoxal [13][14][15], glutaraldehyde [16], and natural or synthetic polymers [17][18][19] have been studied, exhibiting some crease-resistant effects. However, they have various disadvantages.…”

Silk, a natural protein fiber, is widely used in the textile industry and biomedical materials for its excellent properties. However, its application in some fields is seriously restricted due to its poor anti-wrinkle behavior. In this study, 2,4,6-trichloropyrimidine (TLP) was used in the production of anti-wrinkle silk fabrics. The optimum finishing conditions were as follows: 3-g/L 2,4,6-trichloropyrimidine, 6-g/L NaHCO3, 8-g/L Na2SO4, finishing temperature of 65 °C, and finishing time of 40 min. The crease recovery angle of the finished fabric is 16–20% higher than the unfinished fabric, and the finishing process has a small effect on the whiteness of silk while achieving some degree of washing resistance. The morphology and chemical structures of the finished silk fabric were characterized by scanning electron microscopy and Fourier transform infrared spectroscopy. The K/S value of the finished silk fabric dyed with reactive dyes increased compared with the silk fabric only dyed, indicating that the dyeability of the finished fabric was improved. This technology provides a new method for fabricating silk color crease-resistant fabrics.

“…More recently these drawbacks have overcome by using alternative applications of epoxides such as pad‐batch, pad‐dry‐steam, and pad‐dry‐bake 18, 19. Moreover, water soluble multifunctional and silicone‐containing epoxides were synthesized to obtain fabrics with increased wet resiliency without hand worsening 20–26…”

Silk grafting with methacrylic and epoxy monomers was studied with the aim to obtain high graft yields. With both monomer types optimum operating conditions of thermal grafting in water bath were established. In particular, three epoxy monomers were tested at various concentrations, at different temperatures and reaction times, with sodium chloride or sodium thiosulphate as catalysts. Optimum yields (76-82%) were found with Araldite DY-T for 2 h at 708C with 3M sodium chloride. The results were compared with those obtained with the same monomers by UV curing, radical with methacrylates and cationic with the epoxy resin. The UV curing efficiency was tested by gel content determinations. Thermal and UV cured fibers were then subjected to measurements of fibroin solubility in ethanolcalcium chloride-water mixture to evaluate the crosslinking degree. Except in the case of methacrylamide, radical UV curing yielded fibers more crosslinked than thermal treatment, or crosslinked to the same extent, whereas cationic UV curing showed lower crosslinking effects. The grafted fibers were characterized through DSC measurements and FTIR-ATR spectrometry. Finally, surface morphology of UV-cured samples was investigated through SEM analyses which showed that the better products could be obtained with UV curing at low add-on, mainly with dimethacrylates and Araldite DY-T, whereas the thermal grafting seems to be preferable for high add-on.

“…Silk is one of the most luxurious and beautiful natural fibers, possessing excellent luster, wearing comfort, soft handle, good air permeability, superior draping quality, and aesthetic appearance among materials. 1–4 The amino acid compositions of silk protein are close to that of the human skin; hence, it can be used in biomedical applications such as sutures, prosthetic arteries, and bandages. 5 However, unlike polyester or wool fabrics, 3 which maintain their appearance while being worn, silk fabrics suffer from certain disadvantages such as heavy creasing and staining, resulting in considerable inconvenience in the wearing of silk fabrics.…”

“…8,10,11 The conventional crease-resistant finishing of silk fabric is realized by the dip-padding process in which the resin chemicals react on the fibers. 1 A large amount of water is required to prepare the finishing agent in which the silk fabric is dipped and a vast amount of energy is consumed to evaporate the water from the fabric later in the drying and fixation stage. 12 In addition, due to the pick-up of fabric reaching about 80%, the finishing liquid is prone to migration during the curing, which will result in an uneven distribution of finishing agent on the treated fabric and influence the crease resistance.…”

A dual-function silk fabric possessing crease-resistance and hydrophobicity is obtained by one-step foam finishing. A system with a high foaming ratio, containing hydrophobic reagent, crease-resistant agent, and foaming agent, is achieved by optimizing the hydrophobic agent. The results show the foamability and foam stability of finishing solution are enhanced slightly with the increase of the foaming agent dosage. The hydrophobicity and crease-resistance of the treated silk fabric are significantly improved. The contact angle of the treated silk fabric is increased to 132.6 ± 0.7° with the hydrophobic agent addition; meanwhile, the crease recovery angle was improved from 212.5 to 230.3° compared with the silk treated by crease-resistant agent, resulting from the cross-linking reaction of hydroxyls between the hydrophobic agent and silk fabric. SEM images reveal that the surface roughness of the finished silk fabric exhibits an obvious enhancement, indicating a film is formed by the resin curing on the fabric surface, which also explains why the crease-resistance and hydrophobicity of silk fabric are improved. The tearing strength retention ratio is increased 160% after the one-bath finishing of crease-resistant reagent and hydrophobic agent, and the breaking strength of the silk fabric is well maintained. The one-step foam finishing is a facile and energy-saving technology to endow the silk fabric with crease-resistance and hydrophobicity dual-function.
