Description
Technical field
The invention belongs to fabric preparation technical fields, and in particular to a kind of preparation method of underwear antibacterial blended yarn weaved fabric.
Background technique
Bamboo grows fast, updating decision, is distributed wide, yield height, big etc. with intensity height, good toughness, hardness compared with timber
Feature is the desirable feedstock of structural wood and undulation degree, has been widely used in building industry, handicraft, agricultural and fishery.
Due to bamboo fiber hygroscopicity, gas permeability, in terms of there is more superior performance, research spinnability bamboo is former
Fiber has apparent economic benefit and good social benefit.
The chemical component of natural bamboo fibres is mainly cellulose, hemicellulose and lignin, and three belongs to high glycan, always
Amount accounts for 90% of fiber dry mass or more.Just because of the composition of natural bamboo fibres, manufactured bamboo fibre class fabric, under high temperature,
The internal structure of destructible bamboo fibre, causes bamboo fibre fabric to generate a large amount of contractions, and inconvenience continues to use.Described bamboo fibre fabric
Only washable, dry-cleaning, room temperature washing, are unable to high temperature immersion, and when hand washing can not strongly rub back and forth；It cannot be dried when machine washing, clearly
It is dried at ventilation lucifugal after washing, is unable to exposure, be unable to hot iron.
The main ingredient of cotton fiber is cellulose, and cellulose is natural polymer, the chemical structural formula of cellulose
It is that basic structural unit repeats to constitute by α glucose；Cotton fiber has good hygroscopicity, intensity, comfort strong, but cotton is fine
Dimension itself does not have antibacterial, bacteria resistance function, and cotton products antibiotic property is poor, intolerant to mould.
