Problems solved by technology

[0004] The existing flame-retardant and antibacterial bed sheet fabric uses silver ion antibacterial agent. After the silver ion antibacterial agent is sprayed, dried and washed, it is easy to fall off from the bed sheet, resulting in poor antibacterial properties and antibacterial durability of the bed sheet.

Abstract

The invention discloses an antibacterial bed sheet and a production process thereof. The production process comprises the following steps: (S1) fabric preparation; (2) antibacterial treatment: puttingthe bed sheet fabric into antibacterial treatment liquid, heating the antibacterial treatment liquid to 50-60 DEG C, and soaking for 10-20 hours; (S3) padding an drying: after the antibacterial treatment, padding the bed sheet fabric until the rolling rate is 70%-80%, baking the bed sheet fabric at 80-85 DEG C for 3-5 minutes, and then baking the bed sheet fabric at 100-120 DEG C for 1-3 minutes;(S4) washing and dehydration: washing the dried bed sheet fabric in clean water, and dehydrating the bed sheet fabric until the water content of 50%-60%; (S5) steaming: steaming the dehydrated bed sheet fabric at 100-110 DEG C for 3-5 minutes; and (S6) vacuum microwave drying. The production process has the advantages that the operation process is simple, and the prepared bed sheet has a good antibacterial property and a long antibacterial effect.

Description

technical field [0001] The invention relates to the technical field of fabric processing, more specifically, it relates to an antibacterial bed sheet and a production process thereof. Background technique [0002] The bed sheets are mostly made of cotton. After many times of use and without washing for a long time, a certain amount of bacteria will grow on the sheets, among which E. coli is a great hazard. If Escherichia coli is multiplied in large quantities, it will cause some diseases in the human body. Similarly, the proliferation of Staphylococcus aureus will also increase the risk of people getting sick. When finishing the bed sheets, let the bed sheets have a strong and significant inhibitory effect on Staphylococcus aureus and E. coli, which can reduce the chance of people getting sick. [0003] In the prior art, the Chinese invention patent application document with the application number CN201810548308.8 discloses a method for making a flame-retardant and antibac...
