The method has the advantages of simple process and high production efficiency, the obtained slenderized wool has silky luster and hand feeling, the fineness, the dispersion rate and the short-haired rate of the wool are equivalent to those of ordinary wool with the same fineness, and the fiber strength of the wool is improved by 20% in comparison with that of the ordinary wool with the same fineness.

The invention discloses a biomodification method of lactic acid fiber with good spinnability, which is prepared by the following method: adding various raw materials into a high-speed mixer, and dispersing at high speed to obtain a modified polylactic acid mixture; uniformly mixing The modified polylactic acid mixture is melt blended and extruded through a twin-screw extruder to obtain a modified polylactic acid masterbatch, and vacuum dried; the modified polylactic acid functional masterbatch chips and vacuum dried ordinary polylactic acid chips are put into high-speed mixing The mixture is evenly mixed in the machine, and the mixture is spun on a melt spinning machine through circular spinneret holes to obtain modified polylactic acid fibers, and then undergoes microbial modification and strictly controls the fermentation parameters. Different from ordinary constant temperature fermentation, certain instantaneous heat treatment is adopted. The purpose of shortening the fermentation time and obtaining an unexpected modification effect can be achieved.

The invention discloses a stone surface protective nano-coating, which comprises the following formula (parts by weight): 24-26 nanometer silicon dioxide; 24-26 butanol; 4.5-5.5 butyl acetate; 4.5; ethyl carbamate 2.5~3.5; methyl methacrylate 1.5~2.5; acrylic acid 14.5~15.5; butyl acrylate 5.5~6.5; hydroxyethyl acrylate 6.5~7.5; Ethylene glycol monobutyl ether 3.5~4.5. The invention also discloses a process for preparing the stone surface protective nano coating. The coating can be applied to the surface protection of various stone products such as building interior and exterior walls, stone floors, stone guardrails, and stone countertops. At room temperature, it can penetrate deeply into the surface of the stone, forming a dense, transparent, hard protective film on the surface of the stone, preventing various diseases of the stone, and improving the fullness, color saturation, texture, permeability and surface of the stone itself. Hardness and has the ability of easy cleaning and stain resistance.

The invention provides a reactive dyeing method for pearl viscose fibers. The reactive dyeing method mainly comprises the following steps of: dyeing, wherein reactive dyes, sodium carbonate and sodium sulfate are added in water to form dye liquor, pearl viscose fiber fabric is put into the dye liquor after the dye liquor is heated to be at a temperature ranging from 50 DEG C to 60 DEG C, the liquor ratio equals to (25-30):1, the pH of the dye liquor equals to 6 to 7.5, and then the dye liquor is heated continually to reach a temperature ranging from 70 DEG C to 100 DEG C and is kept at the temperature for 80 minutes to 100 minutes, thereby dyeing the fabric; washing the dyed fabric till the fabric is neutral; and drying the fabric. According to the dyeing method, the composition and component proportion of the dye liquor are optimized, the parameters of the dyeing process are adjusted, the dyeing is easy, and the dye-uptake and color fastness of the pearl viscose fibers are improved.
