Description
Technical field
The invention belongs to regeneration cotton production technical fields, and in particular to a kind of preparation method of antibacterial regeneration cotton.
Background technique
China is textile production big country, therefore can all generate largely discarded cotton, industrial waste and weaving daily
The leftover of bolt of cloth and yarn and thread head of enterprise, these textile wastes are discarded as rubbish or one falls baked wheaten cake, not only cause serious
Waste, and polluted environment, or even generate carcinogenic dioxin, endanger the health of people.With population in the world play
Increase, countries in the world all will control arable land utilization, cotton, fiber crops, sericulture the plantation of mulberry tree be all limited, traditional cotton spinning
Raw material is by multiple restriction, and this promotes the exploitation of regeneration cotton and utilizations.
The development and utilization of regeneration cotton can not only alleviate the status of textile industry shortage of resources, but also can reduce weaving
Product pollution on the environment is benefited the nation and the people containing very big economic benefit and social benefit.General regeneration cotton can be summarized as
Three categories type: the first kind refers to unginned cotton during suede is shelled in cotton ginning, " card sweeps " and " infertile unginned cotton " that process equipment is discharged
Deng.Second class refers to " tack rag " that is formed in the production of cotton mill, " hard waste head " etc..Third class refers to weaving mill defective cloth, clothes
The materials such as the cloth corner material that factory cuts.
Regeneration cotton it is widely used, be usually used in making mop, gloves, towel, bedding, clothing item etc..But due to
Regeneration cotton is cotton made of being re-worked using the textile raw material of recycling, and not only raw material contains impurity, but also the middles such as bleaching
Science and engineering skill can bring pollution to regeneration cotton products, influence the wholesomeness and usage comfort of finished product.In addition, since raw material is by opening
Pine, there is also fibre lengths to shorten, strength decline, light resistance is poor, is easy the defects of mildew, and which limits the benefits of regeneration cotton
With.
Therefore, how to produce durable, the good natural environmental-protective again of antimildew and antibacterial effect regeneration cotton is that people constantly solve
New problem certainly.
