The application discloses a camel hair fiber degreasing and separating method based on biological enzyme-ultrasonic wave cooperation and belongs to the field of textile processing technology. The method is aimed at the problem of high density and smoothness of camel hair fiber scales and special grease components, and combines specific biological enzymes (lipase / esterase) with ultrasonic wave technology. The camel hair fiber is placed in an enzyme-containing treatment liquid, and is treated under ultrasonic wave field with specific frequency (25-60 kHz) and power (0.3-1.0 W / cm2) and suitable temperature (40-50 DEG C). The cavitation effect of ultrasonic wave promotes enzyme liquid penetration and assists in physically separating dense scales, and biological enzymes efficiently and specifically hydrolyze grease, and the two cooperate to realize deep degreasing, gently open the scale structure, and significantly improve the fiber separation degree and cohesion. The method has high degreasing rate (>85%), and can maximize the protection of fiber length, strength and natural luster, solves the technical bottleneck of poor spinnability of camel hair, and is green and environmentally-friendly.

The application relates to the technical field of biological silk production, and specifically discloses a cocoon low-temperature thread-removing pretreatment process, which comprises the following steps: preparing a nanocomposite with a core-shell structure; dispersing the nanocomposite in water to obtain a pretreatment liquid; immersing cocoon in the pretreatment liquid to remove the nanocomposite floating on the surface and form cocoon objects; irradiating the cocoon objects with near-infrared light to make the temperature-sensitive phase change material layer melt and release low-temperature active protease, and obtain pretreated cocoon; and putting the pretreated cocoon into clean water with a temperature of 38-42 DEG C to remove the thread. The nanocomposite with the core-shell structure is loaded into the cocoon through negative pressure penetration and is differentially distributed by using the structural differences of different parts of the cocoon layer. After being heated to the melting point of the temperature-sensitive phase change material layer, the protease is triggered to be released in situ in the cocoon layer, and the effect that the treatment strength and the adhesion strength of the cocoon layer are automatically matched is achieved.
