| Personal hygiene products are often used as a disposable product in order to ensure hygiene.For example,clean wipes,women's sanitary pads,baby diapers,adult incontinence,cosmetic cotton and wound dressing.These products for all to use disposable products,and therefore consumption is huge,especially in the current in the stage of population aging in our country,the elderly health care problem gradually,at the same time open two foetuses policy in recent years,making increased neonatal,infant with sales will increase,this type of product market will enter a new round of expansion and upgrade.The present Chinese society into the high speed development stage,the people's living standards improve,consumption level,consumers also have new requirements about the quality of the product,the product's functionality is request for the producer of the market,in the new period has in addition to the basic performance unexpected additional functional products will be more popular with consumers,but also can improve enterprise's profit.With the improvement of people's comprehensive quality,the people also pay more and more attention to environmental protection issue,articles for daily use of the environmental protection is also consumers and manufacturers need to consider the factors,and with excellent properties of natural fiber began to concern,the characteristics of the main natural harmless products also can improve its value,such as pure cotton,no additives for its advantages of time series dry wet cotton.Natural fibers are the earliest textile fibers that humans have started to apply.They are the most precious wealth in nature and one of the most important products of human life.With the gradually deepening understanding of the nature,human understanding of natural fiber and application ability,some difficult to application of the fiber in the past,also due to technical progress and gradually digging out its excellent properties.The resurgence of hemp fibers is the result of new technologies being applied in this area.Marijuana is a traditional,renewable economic crop that has been widely used by humans for thousands of years.But due to its inherent rigidity and wrinkle,it has been replaced by cotton and chemical fiber over the past 100 years,and the application has been declining year by year.But the study found that marijuana has a unique performance,in the textile,food,medicine,paper making,is very wide application prospect in the field of building materials,to adopt new technology,completely changing the hemp fiber image in people's innate in the mind,and make its coruscate gives new luster.The main research content and conclusions of this topic include the following aspects:1.A mix of hemp fibers and cotton fibers is combed into the web.Hemp fiber because of its nature of the technology of fiber is difficult to separate comb into network,mixed with a certain percentage of the cotton fiber can reduce the difficulty of the comb into network and improve the quality of fabric.2.The ratio of hemp fiber to cotton fiber in proportion to the amount of hemp fiber and non-woven materials has its advantages.Hemp fiber in materials for large proportion of the material permeability can be improved,the tensile breaking strength,but the bending stiffness is larger for its application in health materials.3.Due to the existence of the hemp hemp fiber spunlaced nonwoven materials,surface roughness is bigger and more softness,comfort and flexibility in order to improve the surface to the soft finishing materials.The softness and comfort of non-woven hemp fibers were greatly improved after the soft finishing.4.Through the hemp fiber spunlace non-woven materials,multi-faceted performance testing,its performance can basically meet the requirements as a sanitary material.Through the testing of various properties of hemp fiber water stinging non-woven materials,its performance can be met as a requirement of sanitary materials. |
