By combining the embodiment 1 and the embodiments 2-3 and combining the table 1, the filler, the viscose fiber spinning solution and the plant extract are matched, so that the finished product has the advantages of good moisture absorption and good bacteriostasis and mite prevention, the fabric can keep fragrance for a long time after being washed and dried, and the change of the fragrance fraction is small along with the prolonging of time, which indicates that the prepared fabric has the purpose of quickly absorbing fragrance substances to keep fragrance for a long time; meanwhile, the fiber has better dry breaking strength.

Combining examples 1 and 4-5 with table 1, it can be seen that the weight ratio of the adsorbing material to the coating liquid is different, which affects the inhibition of the fabric on staphylococcus aureus, escherichia coli and mites, and the fragrance retention of the fabric after washing and drying is affected, and the breaking strength of the fiber is affected.

By combining the examples 1 and 6-7 and combining the table 1, it can be seen that the raw material ratio of the propolis liquid to the plant leaching liquor is different, the prepared coating liquid has different coating effects on the filler, and the filler and the viscose spinning solution have good compatibility when the content of the plant leaching liquor is higher, so that the breaking strength of the finished fiber is not easily influenced; the content of the propolis liquid is high, the coating formed by the propolis in the coating liquid is not easy to break better in the fiber preparation process, and the adsorption of the adsorption material on water-soluble fragrant substances in the laundry detergent is easy to influence, so that the fragrance retention degree of the fabric after washing and drying is easy to influence.

By combining the examples 1 and 8-9 and combining the table 1, it can be seen that the difference of the propolis liquid concentration has an influence on the fragrance retention degree of the fabric, the concentration is higher, the envelope formed by the propolis in the envelope liquid is not easy to be broken better, and the adsorption of the adsorption material on the water-soluble fragrant substances in the laundry detergent is easily influenced.

By combining example 1 with examples 10-13 and table 1, it can be seen that the filler in example 10 is not coated with the adsorbent in the preparation process and is not coated with the coating solution, compared with example 1, the fabric prepared in example 10 has poorer inhibition effects on staphylococcus aureus and escherichia coli than example 1, has poorer inhibition effects on mites than example 1, has a similar fragrance retention degree to example 1, and has lower dry breaking strength than example 1; the propolis liquid and the plant extract liquid in the coating liquid have good antibacterial, bacteriostatic and anti-mite effects, and the antibacterial property, the bacteriostatic property and the anti-mite property of the finished fabric can be improved; the compatibility of the adsorption material coated by the coating liquid and the viscose spinning solution is improved, so that the fiber has better mechanical property.

In the preparation process of the filler in the embodiment 11, the bamboo powder and the shell powder are not stirred after being soaked, and compared with the embodiment 1, the dry breaking strength of the fiber prepared in the embodiment 11 is smaller than that of the embodiment 1; the high-speed stirring operation after soaking is explained, the coating liquid can be promoted to permeate into pore structures of the bamboo powder and the shell powder, and the surface of the ground filler can still be loaded with the coating liquid, so that the compatibility of the filler with viscose spinning solution and plant extract is improved, the antibacterial effect and the fragrance retaining effect are ensured, and meanwhile, the mechanical strength is good.

Example 12 in the raw material of the coating solution, the propolis solution is replaced by the plant leaching liquor with the same mass, compared with example 1, the bacteriostatic rates of the fabric prepared in example 12 on staphylococcus aureus and escherichia coli are both lower than that in example 1, the inhibitory rate on mites is lower than that in example 1, and the dry breaking strength is lower than that in example 1; the plant leaching solution and the propolis solution are matched to prepare the coating solution, and the proper viscosity of the propolis solution is matched with the better compatibility of the plant leaching solution, the viscose fiber spinning solution and the plant extracting solution, so that the adsorbing material is stably adhered to a fiber structure, and the fabric has better bacteriostatic, anti-mite and fragrance-retaining effects and better mechanical strength.

Example 13 the raw materials of the adsorbent are replaced with bamboo powder by shell powder of the same mass, compared with example 1, the bacteriostatic rates of the fabric prepared in example 13 on staphylococcus aureus and escherichia coli are both lower than example 1, the inhibitory rate on mites is lower than example 1, and the fragrance retention degree is worse than example 1; the shell powder and the bamboo powder are matched, so that the finished fabric has the advantages of good bacteriostasis, mite prevention and fragrance retention.

By combining the example 1 and the comparative examples 1-4 and combining the table 1, it can be seen that, compared with the example 1, the fabrics prepared in the comparative example 1 have the inhibition rates on staphylococcus aureus and escherichia coli lower than those of the example 1 and the inhibition rate on mites lower than those of the example 1 when the fillers are replaced by the viscose fiber spinning solution with the same mass in the raw materials of the comparative example 1; the filler influences the bacteriostasis rate and the anti-mite condition of the finished fabric; the fragrance of comparative example 1, whether measured immediately after drying or 24h after standing, was rated less than that of example 1 and lost faster as the standing time extended, indicating that the filling had better fragrance retention and was able to achieve long lasting fragrance retention.

Compared with the example 1, the fabric prepared in the comparative example 2 has the advantages that the inhibition rates of the fabric on staphylococcus aureus and escherichia coli are lower than those of the fabric prepared in the example 1, and the inhibition rate on mites is lower than that of the fabric prepared in the example 1; the fiber prepared by matching the plant extract and the viscose spinning solution has the advantages of good bacteriostasis, antibiosis and mite prevention, so that the fabric has the advantages of good bacteriostasis and mite prevention; comparative example 2 the perfume retention of the washed and dried fabric is lower than that of example 1, which shows that the matching of the viscose spinning solution and the plant extract has influence on the perfume retention of the fabric.

Compared with the example 1, the fabric prepared in the comparative example 3 has the fragrance less than that of the fabric prepared in the example 1 after being washed and dried for 0h or 24h, and the fragrance is rapidly lost along with the prolonging of time; the inner structure of the plant functional fiber prepared by taking the viscose as the framework has more pores and has no function of intercepting and slowly releasing the fragrance, so that the fragrance is not easy to be left on the surface of the fabric after the surface is dried, and the fragrance is not easy to be left on the fabric for a long time.

Compared with the example 1, the viscose fiber spinning solution with the same quality is used for replacing the plant extracting solution and the filler in the raw materials in the comparative example 4, the bacteriostatic rate of the fabric prepared in the comparative example 4 on staphylococcus aureus and escherichia coli is smaller than that of the example 1, the inhibitory rate on mites is also smaller than that of the example 1, and the fragrance score is lower than that of the example 1; the viscose spinning solution, the plant extract and the filler are matched, so that the finished fabric has the functions of bacteriostasis, mite prevention and long-acting fragrance retention.
