Antibacterial fabric made of dimension, compared with final finishing antibacterial fabric, anti-bacterial fibre shows the advantage of bigger, has antibiotic property
Can it is excellent, have the characteristics that persistence (washability), be safe and using comfortable.So far, the research weight in antibacterial field
Point, which is changed into a manner of fiber process, assigns final antibacterial fabric performance, substitutes the antibiotic fabric production based on postfinishing process
The washing resistance performance of product, anti-bacterial fibre and fabric further increases.
For PE/PET core-skin types composite short fiber using PE as cortex, PET is sandwich layer, mainly for the production of hot wind, hot rolling nonwoven
Cloth, hot melt adhesive ingredient of the low melting point component (PE) as non-woven fabrics, main body of the high-melting-point component (PET) as non-woven fabrics, extensively
It is general to be applied to hygienic articles, such as wet tissue, children's diaper, adult-incontinence diaper and feminine sanitary napkin.In order to meet sanitary material
Material safety, comfortable requirement, composite fibre positive function, comfort direction are developed, and each major company passes through different works one after another
Skill means assign fiber special performance, such as antibiotic property, durable hydrophilic, water repellent.Only due to the HDPE in composite short fiber
It is to play heat bonding during making non-woven cloth, antiseptic is added, the spinnability of cortex can be affected to be directed at
Fiber broken skin can only add antiseptic in sandwich layer, that is, PET, since core concentration is big, and have the cortex barrier of outside, cause
The antibacterial effect of fiber is bad.
