Embodiment 1

[0035] A process for improving the hygroscopicity of polyester fibers, comprising:

[0036] 1) Preparation of liquid medium

[0037] Take 100 parts by weight of micro-electrolyzed water, 3 parts by weight of brown sugar, 1 part by weight of magnesium chloride, 1 part by weight of calcium chloride, 2 parts by weight of all-purpose flour, 1 part by weight of potassium phosphate and 1 part by weight of zinc sulfate, mix them under a pressure of 0.05MPa, Sterilize at a temperature of 80°C for 15 minutes to obtain a culture medium;

[0038] Add rice vinegar to the culture medium, adjust the pH of the mixture to a slightly acidic environment of 5.6-6.5, and obtain an acidic culture medium; let stand for 24 hours;

[0039] Add the pre-cultivated Myrocaria dewwet seed solution to the acidic culture medium, wherein the amount of the Myrocaria dewwet seed solution is 5% of the volume of the acidic culture medium, and leave it for 48 hours to obtain a liquid culture medium ;

Abstract

The invention discloses a process for improving the hygroscopicity of polyester fibers. The process comprises the following steps: 1) preparation of a liquid culture medium; 2) inoculating: inoculating cellulase strain liquid in the liquid culture medium under the condition that the inoculating volume is 6% of the liquid culture medium, placing the liquid culture medium in an environment at the temperature of 36 DEG C, and standing for 24 h to obtain a treatment stock solution; and 3) treatment: preparing the treatment stock solution with the targeted volume according to step 1) and step 2; and placing to-be-modified polyester fibers in modifying equipment, and soaking for 36 h to obtain the modified polyester fibers. By the process, the activity of the cellulase strain liquid is improvedby a myrothecium roridum seed solution at first, the cellulase strain liquid and the myrothecium roridum seed solution supplement each other and act in a combined manner to modify the surfaces of thepolyester fibers, the hydrophilicity of the surfaces of the polyester fibers is improved effectively, and therefore, the moisture absorption performance is improved.

Description

technical field [0001] The invention relates to the field of polyester fiber modification. More specifically, the present invention relates to a process for improving the hygroscopicity of polyester fibers. Background technique [0002] Polyester fiber (polyester fiber), commonly known as "polyester", is currently the largest variety of synthetic fibers. As an important polymer material, PET is also widely used in many fields such as engineering plastics, biological materials, containers and product packaging. Although it has many excellent properties, its application as information functional materials, biomedical materials and filter materials is limited due to the high hydrophobicity of its surface. Contents of the invention [0003] The invention provides a process for improving the hygroscopicity of polyester fibers, which can effectively improve the hydrophilicity of the polyester fiber surface, thereby improving its hygroscopicity. [0004] In order to achieve th...
