“…Sredstva na bazi N, N ' -dimetilol-4,5-dihidroksietilen uree (DMDHEU) su komercijalno najzastupljeniji proizvodi jer otpornost na gužvanje koja se dobija njihovom primenom je stabilna u uslovima pranja i mokrog čišćenja, jer ugao gužvanja posle 5 minuta nakon 10 ciklusa pranja se smanjuje za 18-22%, a nakon 10 ciklusa mokrog čišćenja 6-9% [9]. Iako u poređenju sa sredstvima za umrežavanje bez formaldehida uzorci dorađenih tkanina imaju veći ugao oporavka i manje skupljanje [10], zbog rizika za zdravlje čoveka (suzenje oči, glavobolje, poteškoće u disanju i pri većim koncentarcijama alergijske reakcije na koži) tradicionalna sredstva sa sadržajem formaldehida nalaze se na udaru sve strožih ekoloških propisa. U tom smislu proučava se primena novih smola, polikarboksilnih kiselina i biopolimera u formulaciji rastvora za doradu protiv gužvanja.…”

The tendency of textile materials to crease is reduced by the finishing process when cross-linked compounds are incorporated in the amorphous phase, which improve the recovery of material after the elimination of the pressure load. Because of adverse effects on human health conventional formaldehyde-based processing compounds are increasingly substituted by new compounds and by use of biopolymers. In the paper, examined is the possibility of using the biopolymer chitosan in combination with reactive resin to improve the physical properties of fabrics made of blended cotton/PES. The use of chitosan in combination with commercial reactant improves the physical characteristics of fabrics, because increasing the concentrations of biopolymer progressively increases recovery angle (a0), quality number (K) and the bursting strength of the treated fabric.

“…Standard kadar formaldehid bebas yang diizinkan OEKO-TEX untuk kain yang tidak bersentuhan dengan kulit seperti outerwear adalah kurang dari 300 ppm [5]. Penelitian Saleemudin et.al dalam penelitian Farzana et.al menunjukkan bahwa penggunaan DMDHEU pada konsentrasi kurang dari 30g/L memberikan nilai formaldehid bebas yang lebih rendah [6]. Zat pengikat silang DMDHEU juga memiliki hasil penyempurnaan anti kusut yang lebih tahan terhadap pencucian,disebabkan oleh ikatan silang yang terjadi didominasi oleh ikatan silang dengan molekul serat sehingga kekuatan ikatannya tidak mudah terhidrolisis ketika proses pencucian [7].…”

Jenis pengikat silang pada penyempurnaan anti kusut berpengaruh signifikan terhadap ketahanan kusut kain dan sifat fisik kain. Pemakaian Melamin Formaldehid (MF) memberikan ketahanan kusut yang lebih baik namun menghasilkan sifat kaku yang lebih tinggi pada kain, sementara Dimetiloldihidroksietilena Urea (DMDHEU) tidak memberikan sifat kaku berlebihan pada kain namun sifat ketahanan kusut yang dihasilkan tidak sebaik MF.Penelitian ketahanan kusut dan sifat fisik kain poliester-rayon (65%-35%) dengan kombinasi MF dan DMDHEU 2 : 5, 3 : 4, 4 : 3, 5 : 2, 6 : 1 dan 7 : 0 terhadap konsentrasi resin total sebesar 70 g/L menunjukkan pengaruh signifikan terhadap sudut kembali dan kekakuan kain sebelum dan setelah 5 kali pencucian berulang serta kekuatan tarik kain. Makin tinggi konsentrasi resin MF, sudut kembali kain dan kekakuan sebelum pencucian makin besar. Perbandingan variasi konsentrasi resin MF dan DMDHEU optimum adalah perbandingan variasi 4 : 3 dengan nilai sudut kembali sebelum pencucian 136 o arah lusi dan 135,4 o arah pakan, sudut kembali setelah 5 kali pencucian sebesar 131 o arah lusi dan 130,4 o arah pakan, nilai kekakuan kain sebelum pencucian 180,36mg.cm arah lusi dan 169,33 mg.cm arah pakan, nilai kekakuan kain setelah 5 kali pencucian arah lusi 103,22 mg.cm dan arah pakan 100,76 mg.cm. Kekuatan tarik kain arah lusi 39,00 kg dan 38,40 kg arah pakan dengan kadar formaldehid bebas sebesar 292,85 ppm.

 Application of different cross-linkers on viscose surface  Investigation of the effects on formaldehyde amount, color, physical properties, softness and wrinkle recovery  Improvements values of free formaldehyde, tensile and tear strength and higher wrinkle recovery Cellulosic-based surfaces, such as viscose and linen, tend quickly to wrinkle, and this is an undesirable property during uses. In this study, it is aimed to investigate their effects on formaldehyde amount, color, tear and tear resistance, modulus of elasticity, softness, and wrinkle recovery angle of surface after applying three different cross-linking chemicals. It has been observed that cross-linking agents had bound to viscose surface, and cross-links were formed between adjacent fibers. Although free formaldehyde values were positively below 75 ppm in all applications, it was seen that color difference and yellowing continued to be a problem. The improvements in breaking and tearing strength were obtained compared to the untreated surface. While lower bending rigidity values were measured for all applications, surfaces had a softer handle after treatments. The higher wrinkle angle values were achieved on the surfaces with an increase in concentration. It was determined that imidazoline gave the best wrinkle angle values among cross-linkers. Figure A. SEM micrographs and FTIR spectrum of cross-linked viscose surface Purpose: The aim of the study is to investigate the effect of different cross-linking chemicals on formaldehyde amount, color, tear and tear resistance, modulus of elasticity, softness, and wrinkle angle of viscose surface. Theory and Methods: In this study, it was chosen viscose fabric and then it was treated by three different cross-linking chemicals, as 80, 115 and 150 g/L of concentration. It was investigated their effects on surface properties after treatments. Results: SEM and FTIR analysis confirmed that the new bonds formed on viscose surfaces after treatments. Conclusion: The use of cross-linking chemicals caused a significant contribution to the physical and wrinkle properties of the viscose surface. The best wrinkle property has been given imidazoline chemical. Considering the fabric properties, 115 g/L application is recommended for all cross-linkers to improve the wrinkle property.
