Problems solved by technology

[0005] In order to improve the hygroscopicity of fibers, people will choose fibers with better hygroscopicity, but the fiber structure will be affected to a certain extent during the processing of fibers, which will reduce the hygroscopicity to varying degrees.
Moreover, because fiber products are often rubbed during use, static electricity is easily generated, and the generation of static electricity will directly affect the quality and service life of fiber products

Embodiment 1

[0041] (1) Modification of chitin fiber: Wet 10kg of chitin fiber with water and stir to make a slurry, then add 1.8kg of polyglutamic acid, 0.5kg of EDCI and 0.35kg of HOBt, heat to reflux state and keep warm React for 5 hours. After the reaction is completed, cool naturally to room temperature, filter, and dry the resulting filter residue at 80°C to obtain modified chitin fibers;

[0042] (2) Opening: the modified chitin fiber is initially opened through a coarse opener, and then sent to a fine opener to make the fiber more fluffy through fine opening;

[0043] (3) Carding: The fiber after opening is fed into a carding machine, and is carded into a fiber web, and the weight per unit area of ​​the carded fiber web is 25g / m 2 ;

[0044] (4) Laying: Feed the fiber web into the web-laying machine, and lay it cross-laid into a web, and the number of paving layers is 6 layers;

[0045] (5) Drafting: Slowly draw the laid net through a drafting machine, and the vertical traction m...

Embodiment 2

[0048] Taking Example 1 as a comparison, set Example 2 for antistatic treatment, and the rest of the operations are exactly the same as Example 1. The water-based antistatic agent is prepared by dissolving sodium dodecylbenzenesulfonate in water, and the mass concentration is 10wt%.

[0049] (1) Modification of chitin fiber: Wet 10kg of chitin fiber with water and stir to make a slurry, then add 1.8kg of polyglutamic acid, 0.5kg of EDCI and 0.35kg of HOBt, heat to reflux state and keep warm React for 5 hours. After the reaction is completed, cool naturally to room temperature, filter, and dry the resulting filter residue at 80°C to obtain modified chitin fibers;

[0050] (2) Opening: the modified chitin fiber is initially opened through a coarse opener, and then sent to a fine opener to make the fiber more fluffy through fine opening;

[0051] (3) Carding: Send the opened fibers into a carding machine and card them into a fiber web;

[0052] (4) Antistatic treatment: apply w...

Embodiment 3

[0057] Taking Example 1 as a comparison, set Example 2 for antistatic treatment, and the rest of the operations are exactly the same as Example 1. The water-based antistatic agent is made by dissolving polyglutamic acid in water, and the mass concentration is 10wt%.

[0058] (1) Modification of chitin fiber: Wet 10kg of chitin fiber with water and stir to make a slurry, then add 1.8kg of polyglutamic acid, 0.5kg of EDCI and 0.35kg of HOBt, heat to reflux state and keep warm React for 5 hours. After the reaction is completed, cool naturally to room temperature, filter, and dry the resulting filter residue at 80°C to obtain modified chitin fibers;

[0059] (2) Opening: the modified chitin fiber is initially opened through a coarse opener, and then sent to a fine opener to make the fiber more fluffy through fine opening;

[0060] (3) Carding: Send the opened fibers into a carding machine and card them into a fiber web;

[0061] (4) Antistatic treatment: apply water-based antist...

Abstract

The invention discloses a processing technology of biodegradable medical high-moisture absorption fiber, and relates to the technical field of fiber processing. The processing technology comprises thefollowing steps: (1), modifying chitin fiber, (2), opening, (3), carding, (4), lapping, (5), drafting, (6), reeling. By the processing technology, control condition parameters are clear, the technology is good in repeatability, and the processed fiber is soft in hand feel and excellent in moisture absorption performance and antistatic performance and can be biodegraded after being discarded; theprocessing technology is applicable to processing of various medical products.

Description

[0001] Technical field: [0002] The invention relates to the technical field of fiber processing, in particular to a processing technology of biodegradable medical high hygroscopic fiber. [0003] Background technique: [0004] Fibers are widely used in the medical field and can be made into various medical supplies, including disposable masks, protective clothing, surgical gowns, isolation gowns, surgical kits, maternity kits, first aid kits, diapers, shoe covers, etc. In order to prevent these medical supplies from polluting the environment after they are discarded, people have begun to use biodegradable fiber materials to prepare these medical supplies. [0005] In order to improve the hygroscopicity of fibers, people will choose fibers with better hygroscopicity, but the fiber structure will be affected to a certain extent during the processing of fibers, which will reduce the hygroscopicity to varying degrees. Moreover, since fiber products are often subjected to frictio...
