一、棉柔巾的优势
 
有孩子的家庭,应该都用过棉柔巾。棉柔巾比起传统的纸巾,好在哪里?
 
湿水不易破,不掉屑。婴儿湿巾很常见的用途,就是换洗用,如果掉下来的纸屑黏在宝宝身上,不仅宝宝不舒服,大人也需要更多时间清理。
 
更为柔软。婴儿肌肤娇嫩,一般的纸巾是植物纤维甚至化学纤维做的,不如棉柔巾柔软舒适。
 
随用随扔。比起不那么经常更换的毛巾来说,棉柔巾更适合洗脸后吸干水分,甚至可以做化妆棉使用。
但是,除了这几条之外,往往有一条很重要的因素被大家忽视,也就是,棉柔巾,是不是棉花做的?很多棉柔巾,其实并不是棉花做的!
 
二、无纺布分类介绍
 
拿到一盒棉柔巾,很多时候,材质上写的是无纺布。无纺布是什么呢?无纺布其实是一种制作工艺的总称,而非原料,其原料除了棉花之外,还有竹、木、涤纶等。
无纺布由包括化学纤维和植物纤维等在以水或空气作为悬浮介质的条件下在湿法或干法抄纸机上制成,虽为布而不经纺织故称其为无纺布。无纺布是新一代环保材料,具有强度好、透气防水、环保、柔韧、无毒无味,且价格便宜等优点,又具有拒水、透气、柔韧、不助燃、无毒无刺激性、色彩丰富等特点。
无纺布以其制作工艺的不同,分为以下几种。
水刺无纺布。以高压水流加固纤维网而成,以其强度高、不易起毛、高吸湿性、垂顺度好,成为医用包扎材料及伤口敷料、航空抹布、电子行业高级抹布、毛巾、化妆棉、湿巾、口罩包覆等的主要材料。
 
热合无纺布。以纤网中加入粘合加固材料制制作,多生产婴儿尿片和妇女卫生巾包覆材料、药膏基布等。
 
浆粕气流成网无纺布。以气流冲击加固纤网,吸湿性极强,多用于高吸水性的一次性卫生用品,如尿不湿、卫生巾等。
 
湿法无纺布。用水为介质使得纤维成网,多用于茶叶袋、吸音材料、墙纸等。
 
纺粘无纺布。用长丝制作的特殊无纺布,牺牲了手感,带来了良好的拉伸性能。农用材料、地毯基布、过滤材料很多都用这种。
 
熔喷无纺布。用细丝在高热下挤压而成的无纺布,强度比较差,手感很柔软。服装行业多用这种无纺布。
 
针刺无纺布。利用刺针穿刺做成的无纺布,性能比较均衡,弹性、通透性、手感俱佳,应用也十分广泛。
可以看出,无纺布的工艺已经十分成熟,应用范围也很广泛,覆盖了大多数行业。目前婴儿湿巾优先域,用的比较多的是水刺无纺布和针刺无纺布。那么,问题是什么呢?问题其实是由于成本和工艺技术的问题,无纺布的原料,很多采用的是聚丙烯(pp材质),只有少数用棉质、木浆。
用非天然制作的无纺布,在环保角度考虑,PP材质的回收,还没能达到系统化,对环境有一定影响;在手感和使用性能角度考虑,部分湿巾用无纺布的工艺,确实还差强人意,没有达到母婴行业对无纺布的要求——柔软、吸水、不掉屑。所以,对无纺布的担忧,也是有一定道理的。
 
这方面,全棉时代是如何做的呢?由医疗行业转向母婴行业的全棉时代,用的是全棉无纺布,制作过程申请了专利技术,采用的是100%棉的原料,柔韧经用,干湿两用,吸水不掉屑,完全可降解。棉柔巾真是太神奇了。
I. advantages of cotton soft towel
 
Families with children should have used cotton towels. What's better about cotton soft tissue than traditional paper towel?
Wet water is not easy to break and crumbs will not fall. Baby wipes are commonly used for changing and washing. If the fallen paper scraps stick to the baby, it will not only make the baby uncomfortable, but also make adults need more time to clean them.
 
Softer. Baby's skin is delicate, and the general tissue is made of plant fiber or even chemical fiber, which is not as soft and comfortable as cotton soft tissue.
Throw as you use. Compared with the towel that is not often replaced, cotton soft towel is more suitable for absorbing moisture after washing face, and even can be used as cosmetic cotton.
 
However, in addition to these, there is often a very important factor ignored by everyone, that is, is cotton soft towel made of cotton? Many cotton soft towels are not made of cotton!
 
II. Classification of non-woven fabrics
Get a box of cotton soft napkins, many times, the material is non-woven. What is non-woven fabric? In fact, non-woven fabric is a general term of production technology, rather than raw materials. In addition to cotton, its raw materials include bamboo, wood, polyester, etc.
The non-woven fabric is made of chemical fiber and plant fiber on wet or dry papermaking machine under the condition of water or air as suspension medium. Although it is cloth without spinning, it is called non-woven fabric. Non woven fabric is a new generation of environmental protection material, which has the advantages of good strength, permeability and water-proof, environmental protection, flexibility, non-toxic and tasteless, and low price. It also has the characteristics of water-resistant, breathable, flexible, non combustion supporting, non-toxic and non irritant, rich color, etc.
The non-woven fabrics are divided into the following categories according to their different manufacturing processes.
Spunlaced nonwoven. It is made of fiber mesh reinforced by high-pressure water flow, with high strength, not easy to fluff, high moisture absorption and good verticality. It has become the main material of medical binding materials and wound dressing, aviation dishcloth, advanced dishcloth in electronic industry, towel, cosmetic cotton, wet towel, mask covering, etc.
 
Heat bonded non-woven fabric. It is made by adding bonding and reinforcing materials into the fiber mesh, and more baby diapers, women's sanitary napkins, ointment base cloth, etc. are produced.
 
Pulp air flow into a mesh of non-woven fabric. With the air impact strengthening fiber mesh, the moisture absorption is very strong, and it is mostly used for disposable sanitary products with high water absorption, such as diapers, sanitary napkins, etc.
Wet non-woven fabric. Water as the medium to make the fiber into a net, mostly used for tea bags, sound-absorbing materials, wallpaper and so on.
Spunbond nonwovens. The special non-woven fabric made of filament has good tensile properties at the expense of hand feeling. Many agricultural materials, carpet base cloth and filter materials are made of this kind.
Melt blown non-woven fabric. The non-woven fabric is extruded with fine silk under high heat, with poor strength and soft hand feel. This kind of non-woven fabric is widely used in the clothing industry.
Needled non-woven fabric. The non-woven fabric made of needle puncture has relatively balanced performance, good elasticity, permeability and hand feel, and is also widely used.
It can be seen that the process of non-woven fabric has been very mature, and its application range is very wide, covering most industries. At present, in the field of baby wipes, Spunlaced and needled non-woven fabrics are widely used. So, what's the problem? The problem is actually due to the problems of cost and technology. Many of the raw materials of non-woven fabrics are made of polypropylene (PP), and only a few of them are made of cotton or wood pulp.
From the perspective of environmental protection, the recycling of PP material has not been systematized, which has a certain impact on the environment. From the perspective of hand feeling and use performance, the process of using non-woven fabric for some wet wipes is really unsatisfactory, which does not meet the requirements of the maternal and infant industries for non-woven fabric: soft, water absorbing, and non chip dropping. Therefore, there is a certain reason to worry about non-woven fabrics.
In this regard, how did the cotton age do? In the era of all cotton from medical industry to maternal and infant industry, all cotton non-woven fabric was used. Patent technology was applied in the production process. 100% cotton raw material was used. It is flexible, economical, dry and wet. It can absorb water without removing chips and is completely degradable. Cotton napkins are amazing.
