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.
Highlights
Cotton fabric, a green natural cellulose product, is highly popular in our daily life due to its outstanding properties, such as softness, high hygroscopicity, biodegradability, air permeability, and comfort [1,2,3,4,5]
We explored a highly stable emulsion of chloropyrimidine compounds to improve the antipilling behavior of cotton fabric without affecting its wearability
The antipilling grade of the modified cotton fabric increased gradually with the concentration of TLP dispersions ranging from 0.5 g/L to 3.0 g/L
Summary
A green natural cellulose product, is highly popular in our daily life due to its outstanding properties, such as softness, high hygroscopicity, biodegradability, air permeability, and comfort [1,2,3,4,5]. Many interesting and advanced applications related to natural cellulose materials have been reported [6,7,8,9,10]. With the improvement of living standards, people have higher and more complete requirements of textile quality and functionality. The poor antipilling behavior of cotton fabric restricts its application in the textile industry. It is meaningful to develop an efficient and industrialized method to produce high quality cotton products with excellent antipilling behavior
