Description
Technical field
The present invention relates to composite material preparation technical field more particularly to a kind of preparation sides of reverse osmosis compound nonwoven cloth
Method.
Background technique
Regenerated celulose fibre is common fibrous raw material in textile material, is respinned after usually dissolving cellulosic material
Silk is made.Because dissolution process discharges cellulose molecular chain, moisture pick-up properties and skin affinity are improved.Regenerated fiber
It is common in cellulose fiber to obtain kinds of fibers such as Modal fibre, tencel fiber, rich and powerful viscose rayon (rich and powerful viscose rayon) and cuprammonium
Fiber.
Modal fibre is koplon, is regenerated celulose fibre.The fiber is using timber as raw material, through beating
Slurry, spinning form.Unformed area is small in fiber, and macromolecular arrangement is more neat, closely knit；Cross section is circle, and surface is smooth flat
Whole, the official regain of Modal fibre is 13.0%.
Tencel fiber is also known as Lyocell fibers, is to be with wood pulps for solvent with N-methylmorpholine-N oxide (NMMO)
Raw material, using regenerated celulose fibre made of dry-wet spinning method.Lyocell fibers are soft, drapability is good, inhale and put
Wet ability is strong, and possesses preferable hydrophily, hygroscopicity.The regain of Lyocell fibers is up to 13%.
It is wet strong higher than common viscose glue that rich and powerful viscose rayon, that is, polynosic is that a kind of intensity is especially, and elongation at break is smaller
Fiber.The official regain of rich and powerful viscose rayon is 13%.
Copper ammonia fiber is that cellulose pulp (mainly Cotton Pulp) is dissolved in the dense regeneration of Kocide SD or alkaline cupric salt
In cellulose fibre solution, it is made into spinning solution, is filtered with after deaeration, is spun in the coagulating bath of water or dilute alkaline soln
Shape.The hygroscopicity of regenerated celulose fibre is similar to viscose glue, and regain is up to 12~13%.These fibers are in terms of moisture pick-up properties
It is significantly better than that hydrophilic fibers, the water-absorbing-retaining ability of fiber is stronger.
Unidirectional water guide fabric in non-woven material is common type, keeps dry and comfortable with the one side of skin contact, another
Face energy water-absorbing-retaining, to realize the one-way conduction of water.Chinese patent application Authorization Notice No. CN2331362Y, date of declaration
On 08 04th, 1999, entitled amenities surface dry, the unidirectional sepage fiber mesh fabric of innovation and creation, this application
Case discloses a kind of amenities surface dry, unidirectional sepage fiber mesh fabric, and fabric is by hydrophobic fiber layer and hydrophilic fibre
Polymer material layer is pressed from both sides between dimension layer, is bonded or pressed composition.Liquid-leadage hole on hydrophobic layer is processed into shape of various shapes
Shape, and arranged with certain pattern.Its deficiency is: realizing that the key of the unidirectional osmosis of fabric is intermediate high molecular material
Layer, product use big to environmental protection pressure after discarding.
Bombax cotton is silk cotton tree fruit fiber, and longitudinal appearance is cylindrical, and surface is smooth, not aobvious to turn song, good luster；It
Antibiotic rate be 99.4%, drive mite rate be 87.54%.Non-woven cloth is prepared using bombax cotton and is also disclosed report.
Chinese patent application Authorization Notice No. CN1884656B, date of declaration on November 23rd, 2011, the name of innovation and creation
The referred to as production method of kawo fiber spunlaced fabrics, this application discloses a kind of lifes of kawo fiber spunlaced fabrics
Production method mixes kapok with hydrophilic fibers, then carries out spun lacing and obtain kawo fiber spunlaced fabrics.Its deficiency is: wood
Cotton fiber and hydrophilic fibers mixing shredding, fiber are uniformly mixed, and non-woven cloth tow sides are identical to the permeability of water, are not present
Reverse osmosis function.
Chinese patent authorization publication No. CN100491630C, date of declaration on May 27th, 2009, the title of innovation and creation
It is bombax cotton in the manufacturing method and application of non-weave non-woven fabrics field, this application discloses a kind of pair of bombax cottons to carry out
The method that additive, auxiliary agent and the application bombax cotton of pre-treatment manufacture non-weave non-woven fabrics.Using additive to bombax cotton
Pre-treatment is carried out, the raw materials such as bombax cotton and various natural fibers, staple fibre, synthetic fibers are mixed by treated, then
Networking is combed, fibre web reinforcing is carried out, after the completion of fibre web is reinforced, kapok fiber raw material weight 1.5- is added in sizing groove
5% auxiliary agent carries out rubber cement, increases its intensity, gets product using high-temperature shaping.Its deficiency is: by kapok in the patent
Fiber and other fibers are mixed and made into non-woven material, cannot utilize the water repellent characteristic of kapok well.
