The present application relates to a strain of Inhernia Bacillus and its application in ramie degumming, the strain is preserved in Guangdong Microbial Culture Collection Center on September 15, 2025, and the preservation number is GDMCC NO: 66966. When the strain is applied to ramie degumming, the degumming reaction can be carried out at a higher temperature, the degumming efficiency of ramie is effectively improved, the fiber is not damaged, the quality of the fiber is improved, and the strain has high application value in ramie degumming.

This invention discloses a strain of *Bacillus spp.* from soil, which was deposited at the Guangdong Provincial Center for Microbial Culture Collection on September 15, 2025, with accession number GDMCC NO.66967. This strain exhibits good heat resistance, and the mannanase it produces maintains stable enzyme activity under high-temperature conditions. Compared to hydrolases under ordinary conditions, it has greater plasticity and is suitable for the production of products or by-products in multiple fields. In addition, this strain can also be applied to the degumming process of hemp fibers, demonstrating excellent degumming effects on hemp fibers.

The application discloses a blended antibacterial and anti-wrinkle school uniform fabric and a preparation method thereof, and has the characteristics that the fabric preparation comprises the following steps: S1, fresh first-class flax stalks are washed with clean water, dried and bundled; S2, the flax is retted with warm water; S3, the flax stalks after the warm water retting are washed, dried, mechanically crushed, beaten, combed, graded and cut to collect the flax fibers; S4, the flax fibers and fine cotton are blended to obtain blended yarn; and S5, the blended yarn is woven, and the blended antibacterial and anti-wrinkle fabric obtained by the method can be used for school uniform manufacturing.

This invention belongs to the field of natural fiber processing technology and relates to a natural fiber degumming tank system. It includes a cylinder, a screen, a central perforated column, and a central water distribution pipe arranged sequentially from the outside to the inside. A central support pipe is welded to the cylinder, and the central support pipe has a reflux hole. A lower end cap is connected to the cylinder via a flange, and a heating pipe is arranged on the lower end cap. A flapper level gauge is installed on the cylinder, and a liquid inlet is installed on the cylinder with a solenoid valve at the inlet. The flapper level gauge is linked to the solenoid valve. A flat end cap is welded to the screen, and the screen is fixed to the top of the central support pipe by guide rings and positioning rings. The central perforated column is connected to the central water distribution pipe. The system also includes an external circulation pipeline, which enables the external reflux of the degumming liquid, suppressing turbulence and vortices at the inlet and outlet in traditional internal reflux systems, and reducing the risk of blockage by broken fiber fibers. In this invention, the central perforated column is connected to the central water distribution pipe via a trapezoidal internal thread short connector, forming an embedded structure, which facilitates easy installation and disassembly.
