“…Among softwoods, the Pinus, Picea, Larix, Cedrus and Tsuga genus are the most employed in the production of dissolving pulp; and from hardwoods include Eucalyptus, Fagus, Betula, Populus, Acacia, Quercus and Acer genus (Mendes et al 2021). In recent years, investigations have been focused on the use of non-wood raw materials, such as bamboo (Ma et al 2011;Batalha et al 2012;Wu et al 2014Wu et al , 2017Basit et al 2018), bagasse (Andrade and Colodette 2014), jute (Nayeem et al 2017;Sarkar et al 2018), hemp (Zhang et al 2006;Paulitz et al 2017) and corn stalk (Behin and Zeyghami 2009) as potentially suitable raw materials for the production of dissolving pulps (Mendes et al 2021). This is particularly of interest in Asian countries, since the production of dissolving pulp from bamboo has a market in China (Ma et al 2011;Ji and Zhao 2015).…”

The global textile fiber output increased five times from 1975 to 2020. Also, in 2010, the combined demand for man-made and natural fibers was projected to increase by 84% within 20 years. Clothing materials are largely made from cotton or petroleum-based synthetic fibers; both sources, however, have adverse environmental impacts. Thus, cotton requires vast amounts of land, water, fertilizers and pesticides, and synthetic fibers are not biodegradable. This scenario has raised the need for further exploration of cellulose polymers as sustainable sources for the textile industry. Cellulose, the most abundant renewable organic material on earth, is an outstanding polymer that by chemical derivatization or modification can offer a broad range of applications. Dissolving-grade pulp (DGP), which consists of highly pure cellulose, is the most suitable material for manufacturing cellulose derivatives and regenerated fibers. The latter are typically obtained by using the viscose process, which has considerable adverse environmental impacts. Although the textile industry has progressed substantially, further efforts are still needed to make its entire production chain more sustainable. This article provides an in-depth introduction to the potential of fibers with a high cellulose content, known as dissolving-grade pulps. It reviews the properties of DGP, the cooking and purifying methods typically used to obtain it, and the process by which paper-grade pulp can be converted into dissolving-grade pulp. Also, it discusses traditional and recently developed technologies for producing regenerated cellulose fibers. Finally, it examines the potential for recovering cellulose from textile waste as a novel sustainable practice.

“…Proses prehidrolisis kraft melibatkan dua tahapanan yaitu prehidrolisis dan pemasakan kraft. Tahapan prehidrolisis dilakukan sebelum pemasakan kraft, serpih kayu di-steam (Luo, Liu, Wang, Huang, & Chen, 2014) atau diperlakuk an dengan air pada 170 ºC selama 60 menit (Nayeem, Sarkar, Wuadery, & Jahan, 2017) ataupun dengan 0,2%-0,4% asam sulfat 1 N dengan temperatur 160 °C selama 145 menit (Purwita & Sugesty, 2018). Prehidrolisis bertujuan untuk menghidrolisis hemiselulosa dan membantu melonggarkan matriks pulp sehingga meningkatkan aksesibilitas lignin terhadap bahan kimia pemasakan dan pemutihan pulp.…”

<p>Pulp rayon atau pulp larut (<em>dissolving pulp</em>) merupakan pulp dengan kandungan selulosa alfa tinggi dan kandungan komponen lain seperti lignin, abu, abu tak larut asam, kelarutan dalam alkali, dan ekstraktif rendah. Pulp rayon merupakan bahan baku untuk proses pembuatan serat rayon yang digunakan pada industri tekstil dan pakaian jadi. Penelitian ini bertujuan untuk mempelajari karakteristik pulp rayon sulfit asam dan prehidrolisis kraft komersial yang kemudian dibandingkan dengan persyaratan mutu SNI 938:2017 Pulp rayon. Pulp rayon komersial yang diperoleh dari industri pulp rayon dan industri rayon di dalam negeri maupun impor dianalisis sesuai dengan persyaratan mutu SNI 938:2017. Parameter analisisnya adalah kadar air (SNI 08-7070-2005); selulosa alfa (SNI 8400:2017 (T 203 cm-09, IDT)), kelarutan dalam alkali (SNI 692:2010), ekstraktif diklorometana (DCM) (SNI 8401:2017 (T 204 cm-07, IDT)), abu (SNI 0442:2009), abu tidak larut asam (SNI ISO 776:2010), Ca dan Fe (TAPPI T 266 om-18); viskositas (SNI 8402:2017 (T 230 om-13, IDT)); viskositas intrinsik (SNI 5351:2012); dan derajat cerah ISO (SNI 2470-1:2014). Analisis dilakukan dengan 3 ulangan dan hasil dinyatakan sebagai rata-rata. Berdasarkan percobaan, pulp rayon prehidrolisis kraft memiliki kandungan selulosa alfa yang lebih tinggi, S10 dan S18 yang lebih rendah, dan viskositas yang lebih rendah dibandingkan pulp rayon sulfit asam. Dari lima jenis pulp rayon komersial, hanya dua jenis pulp rayon komersial yang memenuhi persyaratan mutu SNI 938:2017. Kedua pulp rayon tersebut merupakan pulp rayon kayudaun proses prehidrolisis kraft.</p>
