The present invention relates to a nonwoven fabric manufacturing method in a textile manufacturing industry, particularly to the manufacturing method for bicomponent spunbonded nonwoven fabric. The technical scheme of the method is characterized in that a compound spinning device is adopted to manufacture composite fibers, and then, the method for manufacturing the bicomponent spunbonded nonwoven fabric is adopted, namely that two screw extruders, two melt filters and a composite spinning box body are adopted, wherein metering pumps and spinneret plates in the composite spinning box body are respectively added by one time. The bicomponent spunbonded nonwoven fabric manufactured by the technical scheme of the present invention has the advantages of good hand feeling flexibility and good water repellency. The bicomponent spunbonded nonwoven fabric can be high grade auxiliary materials for products of disposable medical insurance articles, sanitary articles, other composite materials, etc.
Description
Technical field
Non-weaving cloth manufacture method, the particularly manufacture method of bicomponent spunbond method non-weaving cloth in the manufacturing industry the present invention relates to weave.
Background technology
Spun-bond process non-weaving cloth production process has been a very ripe technology, but in the past, the production of spun-bond process non-weaving cloth all is one-component, production equipment is comparatively simple, causing the product variety dullness of production, wherein is slim hot rolling polypropylene fibre product more than 90%, mainly is some thick type acupuncture dacron products and a small amount of slim hot rolling dacron product in addition, the feel of the product of producing is harder, and flexibility and WATER REPELLENCY are poor.
Summary of the invention
Technical scheme of the present invention be for can overcome spun-bond process non-weaving cloth kind dullness, feel is harder, the manufacture method of a kind of bicomponent spunbond method non-weaving cloth that flexibility and WATER REPELLENCY are poor, prepared product comfortable feel, WATER REPELLENCY and flexibility are all better, the production-line technique of Jian Liing is reasonable simultaneously, the production process compliance with environmental protection requirements.
The manufacture method of bicomponent spunbond method non-weaving cloth provided by the invention is characterized in that it is realized by following steps:
(1) reinforced fusion: the raw material section of two kinds of components adds feed bin respectively, enters melted by heating in the screw extruder respectively, becomes spinning melt through separately melt filtration again;
(2) composite spinning: spinning melt enters the composite spinning case respectively, and metering converges the formation compound silk more respectively;
(3) divide the silk lapping: compound silk disperses to be paved into silk screen:
(4) hot rolling: silk screen is rolled into non-weaving cloth;
(5) reel: the non-weaving cloth coiling.
The manufacture method of aforesaid bicomponent spunbond method non-weaving cloth is characterized in that, the compound silk of described formation can be the compound silk tow.
The manufacture method of aforesaid bicomponent spunbond method non-weaving cloth is characterized in that, it is characterized in that, the structure of described compound silk can be core-skin type, parallel type, fabric of island-in-sea type, tangerine lobe type.
The manufacture method of aforesaid bicomponent spunbond method non-weaving cloth is characterized in that, described silk screen can be disperseed to be paved into by several compound silks.
The manufacture method of aforesaid bicomponent spunbond method non-weaving cloth is characterized in that, distance equates between the compound silk of described branch silk lapping.
The bicomponent spunbond method non-weaving cloth that technical solution of the present invention is made is compared with common spun-bond process non-weaving cloth, its advantage is that pleasant softness is good, tearing strength is high, WATER REPELLENCY good, and it can be used as the high-quality auxiliary material of products such as disposable medical insurance articles for use, amenities and other composites.
The present invention compares with the non-weaving cloth of staple fibre manufacturing, has following advantage:
1) long fiber nonwoven fabrics is different from staple fibre and makes steps such as non-weaving cloth needs to cut off, packs, transports, compresses, shredding, and it can continuous operation, so high efficiency, staffing is few, can reduce cost.
2) PRODUCTS FIELD of the present invention's production all is higher than the staple fibre product to brute force.
3) product of the present invention does not need to add finish in process of production, and is so product belongs to green product, safe and harmless to human body.

The specific embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is further described:
The manufacturing of polyethylene/polypropylene bicomponent spunbond method non-weaving cloth realizes by following steps:
(1) reinforced fusion: the raw material section of section polypropylene and two kinds of components of section polyethylene adds feed bin 1,2 respectively, enter in the screw extruder 3,4 melted by heating respectively and squeeze out screw extruder, entering becomes polyethylene, polypropylene spinning melt after separately melt filtration device 5,6 filters decontaminations again;
(2) composite spinning: polyethylene, polypropylene spinning melt enter composite spinning case 7 by pipeline respectively, two measuring pumps 11,12, subsequently through two isometric melt pipes 13,14, converge to respectively and form the compound silk tow on the spinnerets 15, two blocks of spinneretss are housed in the composite spinning case, the ejection of every block of spinnerets be two bundle compound silk tow.Present embodiment has 48 composite spinning casees, and just the compound silk tow through spinnerets ejection has 192 bundles, and the distance between the 192 synnema bundles all equates, is uniform with the quality of the non-weaving cloth that guarantees to form.The compound silk structure of present embodiment spinnerets ejection is the core-skin type tow.
(3) divide a silk lapping: the 192 bundle compound silk tow that come out from the composite spinning casing are distributed to lapper 8 by the pendulum wire device uniformly with tow and are paved into silk screen;
(4) hot rolling: silk screen is rolled into non-weaving cloth by hot-rolling 9;
(5) reel: the non-weaving cloth that rolls into is coiling on cylinder 10.
The characteristics of the bicomponent spunbond method non-weaving cloth manufacture method that the present invention proposes are to produce single group for the past The production technology of part product has designed the production method that a cover is fit to produce bicomponent spunbond method non-weaving cloth. According to the characteristics of bicomponent spunbond method non-weaving cloth production procedure, the present invention has adopted compound device for spinning system Get composite fibre, produce then the method for two component non-weaving cloths, namely adopt two screw rods extruding machines, two Fondant filter, composite spinning casing, wherein measuring pump, the spinneret in the composite spinning casing increases respectively One times. Two covering devices of producing bicomponent spunbond method non-weaving cloth are symmetric arrays. Employing the present invention establish Prepare that the bicomponent spunbond method non-weaving cloth pleasant softness of getting is good, to refuse water-based good, it can be used as once The high-quality auxiliary material of the products such as property medical insurance articles for use, amenities and other composites.
