Problems solved by technology

The construction of a multilayer absorbent core involves a more complex manufacturing process
This fibrous material is generally not available in preformed roll form because it lacks interfiber bonding or entanglement and does not exhibit sufficient web unwinding and processing directly on absorbent pad manufacturing equipment strength
[0003] Fibers with health care functions are currently one of the research directions that relevant researchers are working on. Fibers with antibacterial and anion-releasing functions are particularly important in the medical and health industry and the automotive interior decoration industry, because the textiles used in the medical and pharmaceutical industries have It may become a carrier of bacteria, causing cross-infection, affecting the recovery of patients, and even endangering life

Abstract

The invention discloses a method for modifying an anti-microbial multifunctional fiber material. An anti-microbial multifunctional master batch is subjected to pre-polymerization reaction, chain-expanding reaction and neutral reaction, so that a modified anti-microbial multifunctional fiber material can be obtained. The anti-microbial multifunctional master batch is prepared from the following components: 4-5 parts by pass of inorganic anti-microbial powder, 5-10 parts by mass of inorganic anti-flaming micro-powder, 10-20 parts by mass of polyethylene wax, 20-30 parts by mass of zinc stearate and 20-30 parts by mass of stearic acid.

Description

technical field [0001] The invention relates to a multifunctional fiber structure containing particles, specifically a method for modifying an antibacterial multifunctional fiber material Background technique [0002] In recent years, there has been an increased demand in the market for increasingly thinner and more comfortable absorbent articles. Such articles can be obtained by reducing the thickness of the diaper core, by reducing the amount of fibrous material used in the core while increasing the amount of SAP particles, or by calendering or compressing the core to reduce the thickness of the diaper and thereby increase its density. In order to maintain proper liquid absorption, it is desirable to place a low density layer with a larger pore size over the high density absorbent core to increase the rate of liquid absorption into the absorbent article. The low density layer is often referred to as the capture layer. The construction of a multilayer absorbent core invol...
