Durable Antipilling Modification of Cotton Fabric with Chloropyrimidine Compounds

Abstract

Cotton fabric, a natural cellulose material, is widely used in the textile industry for its excellent properties. However, its application in some fields are seriously restricted because of its poor antipilling behavior. In this study, cotton fabrics were modified with 2,4,6-trichloropyrimidine (TLP), 2,4-dichloro-5-methoxypyrimidine (DMP), and 2-amino-4,6-dichloropyridine (ADP). The surface morphology and chemical structure of the modified cotton fabric were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD). Furthermore, the antipilling behavior, dyeing properties, thermal properties, and mechanical properties of modified cotton fabric were evaluated. The results showed that chloropyrimidine compounds were successfully grafted onto the surface of the cotton fabric, leading to excellent and durable antipilling activity of grade 3–4 even after 10 washes. Moreover, compared with control cotton fabric, the heat release rate (HRR) and total heat release (THR) of TLP-modified cotton fabric decreased to 173.2 W/g (42.3% reduction) and 11.3 KJ/g (13.7% reduction), respectively. In addition, the increased K/S value of modified cotton fabrics dyed with reactive dyes indicated that the modification can enhance the dyability of cotton fabric. This technique provides a simple and versatile method for improving the antipilling behavior of cellulosic materials and supports further preparation of functional textiles.

Dyeing Property Improvement of Madder with Polycarboxylic Acid for Cotton

“…It could be seen from Table 2 that compared with the raw cotton fabric, the crystallinities of the dyed cotton fabrics were changed approximately ±3%, indicating that dyeing processes had little effect for the crystallinity. XRD results showed that the direct, mordant and cross-linked dyeing mainly occurred on the active surface or amorphous areas, and retained the original crystal of the cotton fabrics [ 27 ].…”

“…The maximum decomposition state was observed in the range of 250 ˚C to 350 ˚C. This corresponded to the decomposition of the cotton cellulose chain into small molecules as shown in figure 5 [14]. In this range, the weight loss was 62.49%, 64.39%, 63.24%, 60.87%, and 57.13% for P/C, I1, I2, I3, and I4, respectively.…”

Photochemical Stability of a Cotton Fabric Surface Dyed with a Reactive Triphenodioxazine Dye

“…After cooling, the metal capsules with the paint fleets were removed from the installation. The dyed samples were washed repeatedly with warm water and cold water and finally rinsed for 15-20 min with 60-70 mL of distilled water, at 80 • C, to completely remove the dye not fixed on the textile fabric [20].…”
