### Effect of Liquid Smoke Treatment on Fiber Crystalline Properties  
The XRD test was conducted to see the effect of liquid smoke treatment on the percentage of compound content, peak crystals, and intensity of BSFs. The XRD test generates graphic information on different treatments of BSFs, as shown in Table 2.  
Table 2 shows the differences in compounds between the untreated fiber and the treated fiber for 1, 2, and 3 h. Where in TP fiber, there are compounds (SiO\({}_{2}\) 87%, C\({}_{12}\)H\({}_{8}\) 7.5%, and H\({}_{2}\)O 5.1%), in P1J fiber, there are compounds (SiO\({}_{2}\) 47% and H\({}_{2}\)O 53%). In P2J fiber, there are compounds (SiO\({}_{2}\) 90% and H\({}_{2}\)O 10%), and P3J fiber contains compounds (SiO\({}_{2}\) 48% and H\({}_{2}\)O 52%). The location points of the different compounds are shown in Figure 5.  
Figure 5 shows the percentage of C\({}_{12}\)H\({}_{8}\) compounds found in TP fibers. On the other hand, P1J, P2J, and P3J fibers do not contain C\({}_{12}\)H\({}_{8}\) compounds, which theoretically \begin{table}
\begin{tabular}{c c c c c} \hline \hline
**No** & **Compounds** & **TP (\%)** & **P1J (\%)** & **P2J (\%)** & **P3J (\%)** \\ \hline
1 & SiO\({}_{2}\) & 87 & 47 & 90 & 48 \\
2 & C\({}_{12}\)H\({}_{8}\) & 7.5 & 0 & 0 & 0 \\
3 & H\({}_{2}\)O & 5.1 & 53 & 10 & 52 \\

Table 2: Percentage of compound changes in fiber. Figure 5: BSF Fiber Compounds (TP, P1J, P2J, and P3J). means that the liquid smoke fiber compounds change after treatment. Furthermore, H\({}_{2}\)O compounds are found in all fibers, as related to the results of tensile and morphological tests, where the water content is minor in P2J fiber. This result proves that the theoretical concept of the treatment method is original, and the H\({}_{2}\)O degradation process occurs in the fiber so that the remaining percentage is only 10%, and confirms that the highest fiber crystalline index occurs in P2J fiber and in line with previous research on the effect of liquid smoke on the crystalline properties of fibers [8; 17]. XRD test results also showed that the intensity of the crystals in the fiber experienced a change where P1J, P2J, and P3J fibers increased compared to TP fibers, as shown in Table 3 and Figure 6.  
Table 3 shows that TP fiber only formed 4 peaks 2-theta, and P1J, P2J, and P3J fibers formed 7 peaks 2-theta, and additionally shows that the fiber treated with third-grade liquid smoke formed crystalline on the fiber. The crystal peak points are shown in the following graph:  
Figure 6 shows the fiber crystallization index increased due to changes in fiber structure, where the highest peak TP BSFs occur at point two, while the highest peak BSFs P1J, P2J, and P3J occur at points two and three, respectively. This result proves that the innovation of BSFs treatment with liquid smoke can change the crystalline properties of fibers, so it has become the latest innovative method in changing the crystalline properties of fibers. \begin{table}
