Abstract
The present invention is a kind of method of making the polyster fibre sheet material, and it makes raw material with the polyster fibre in the polycot blend fabric angle, sneaks into low-melting fiber, dry-laying, strengthen via yarn respectively, the processing of different operations such as acupuncture, welding, cold rolling, hot pressing promptly makes required polyster fibre sheet material again.This sheet material is not mould not to be eaten into, do not have smell tasteless, have no side effect, hydrophobic, can wash, do soon, resistance to chemical attack, tensile strength be big, sound absorption, heat-proof quality are good, and cheap.Can be widely used in many fields such as backing industry, quilt-mosquito net industry, building materials industry, packing business.
Description
Polycot blend fabric angle (hereinafter to be referred as the polyester-mixed cotton cloth angle) can not be used for papermaking, also difficult shredding.If the thin slim poplin cloth class cloth of shredding angle will be split into the very short short flannel of length.This extremely short fiber not only can not be used for waste spinning and acupuncture, can not be with its production low gear dip bonding nonwoven fabric.The present invention has opened up a kind of approach that utilizes for this resource, is made into outward appearance and the performance polyster fibre sheet material of difference to some extent, and it is bulk that it has, what have is pliable and tough, what have is thin and smooth, and the springiness as the felt densification that has is to satisfy the demand of national economy different field.
Technology of the present invention is: (this operation is with reference to US3937675 to remove the cotton fiber at polyester-mixed cotton cloth angle, just this method is difficult to the cotton fento of hydrolysis is removed from spun polyester thread), add short-staple Dacron oil solution again, the compound that contains low-melting fiber is made in shredding, dry-laying, respectively through the processing of different operations such as acupuncture, yarn reinforcing, hot melt, cold rolling, hot pressing, make required polyster fibre sheet material again.It is existing that details are as follows:
One, raw material
The used main material of the present invention is the polyester-mixed cotton cloth angle, comprises that the residual duds of the cutting leftover pieces of rag trade, social output, the loose thread of weaving industry etc., and its source is wide and cheap.The low-melting fiber that the present invention adopts is the reworked material of polypropylene fibre, polyethylene, polyvinyl chloride fibre and bicomponent fibers, also can adopt the staple fibre virgin material of polypropylene fibre, polyethylene, polyvinyl chloride fibre because of the low-melting fiber usage ratio is less, and prepared polyster fibre sheet material remains cheap.
Two, remove the cellulose fibre at polyester-mixed cotton cloth angle
The purpose of this operation is: produce the pure cloth angle of washing to obtain pure polyster fibre; Make the thin yarn in cloth angle loose, so that can shredding go out long fiber, this is the successful necessary guarantee of invention.
Boil through long period strong acid and to boil, repeatedly washing, the pure cloth angle of washing of gained is very clean, and this has also improved the application performance of the polyster fibre sheet material that finally makes.
Technological process: shearing → acid boils → washes → mechanical treatment → rinse water → dehydration → drying.
Description of the process: earlier 40 millimeters * fritter below 40 millimeters is cut at the polyester-mixed cotton cloth angle, in order to avoid tangle agglomerating overslaugh subsequent technique.The condition that acid is boiled is: 10% aqueous sulfuric acid, bath raio boiled greater than 1: 15 and boil 60 minutes.Sulfuric acid concentration be lower than 9% cellulose hydrolysis must the time oversize, bath raio handle to be difficult for evenly less than 1: 15, boiling temperature is to terylene not damaged still.Cloth angle water flushing after the pickling is to neutral, stirs in cold mixer at plastics, makes bump and friction, loses powerful cotton fiber and will rupture in yarn and move, and the cotton fento is with the polyster fibre separation and be suspended in the water when rinsing water.After centrifugal dehydration, only need airing promptly to get pure dried cloth angle for saving the energy.
Three, shredding
Polyster fibre is made through shredding in the pure cloth angle of washing, and the woven dacron angle should add the short-staple Dacron oil solution of 3-4% before the shredding, stacks 24-48 hour, leaves long fiber to improve opener efficient and to be beneficial to.Add the finish that finish can make the polyster fibre that makes contain before the shredding and be more evenly distributed, this is that lapper runs well and obtains the necessary condition of uniform fiber net.For obtaining than long fiber, what the present invention selected for use is brad cylinder opener.
Four, become net
Fiber web thickness unanimity, fiber is three-dimensional arrangement, and low-melting fiber is evenly distributed, and is into the purpose that net will reach, and is the essential condition of making good polyster fibre sheet material.Select suitable mixing device and technology,, can reduce the mechanical damage of fiber again to greatest extent in the hope of the good mixing of terylene and two kinds of fibers of low melting point.What the present invention selected for use is roller cylinder metal needle cloth combing four curtain laying lappers, and it is strong to the adaptability of fiber, and the web properties that makes is good, be other become net arrangement can not compare.As a production constant volume great than thick sheet the time, from saving the energy and reducing the angle of equipment investment, air lay also is the alternative method that can consider.
Five, acupuncture and yarn reinforcing
Except that bulk polyster fibre sheet material, fiber web is made pliable and tough felted polyster fibre sheet material all through pinprick reinforcement, available pure wash yarn warp-wise or warp-weft two-way reinforcement.The present invention elects the 169DF type and gives needing machine, and it can make acupuncture even, and fiber web is straight and not crooked.To determine needling process according to the fibre web concrete condition.Improve depth of needling and density within the specific limits, the unit weight of sheet material is strengthened, tension force and stiffness strengthen.
Six, hot melt and cold rolling
What the present invention adopted is open width individual layer bimetallic net hot blast drying room fuse machine.According to fibroreticulate constant volume weight, compaction rate and determine the temperature of hot blast by the speed of drying room makes the low-melting fiber fusion and fuses at the contact place of fiber.When preparing the polyster fibre sheet material of frivolous need surfacing, can when low-melting fiber still is molten condition, impose cold rolling.The above two all promptly get required finished product through natural cooling, coiling again.
Seven, hot pressing
Through the fiber web of pinprick reinforcement, be cut into and the matched size of press template, be stacked to the constant volume weight of finished product requirement, last machine progressively pressurizes, and slowly heats up.Pressure is different according to product, and temperature will be a little more than the fusing point of low-melting fiber.Treat to be incubated 5-10 minute after the fine fusion of whole low melting points, can go out machine.Through natural cooling, cutting edge, it is even promptly to get thickness, and surfacing, densification and springiness are as the polyster fibre sheet material of massive industrial felt.
Eight, test data
Sample is pliable and tough felted polyster fibre sheet material, without yarn reinforcing, and the heavy 700g/m of constant volume
