Abstract
The invention relates to a non-woven with online added warp and weft yarn and a production method thereof. The present non-woven has poor intensity and durability, high elongation and poor elastic resilience, and cannot be washed repeatedly like textile fabric. The processing steps of the non-woven provided by the invention comprise: firstly, adopting short fiber, unpacking, opening, feeding by air flow, and carding to form a fiber web, transmitting a warp coil and laying warp automatically by a warp beam of a let-off system on surface of the fiber web, beating-up by an airjet beating-up system, interweaving warp and weft yarn, laying the fiber web produced by a second carding machine on the interwoven warp and weft yarn and the fiber web produced by a first carding machine to form a sandwich structure; then passing through a spun-lacing area, under the effect of high pressure water flow, alternating and entangling the upper and lower fiber webs and the middle warp and weft yarn to tightly combine into a whole body. The invention can increase the production rate and efficiency and lower the production cost, and at the same time, can make the product have advantages of both non-woven and textile fabric.
Description
Technical field
The present invention relates to nonwoven field of new, particularly a kind of nonwoven and production method thereof that woven fabric and nonwoven are combined.
Background technology
Non-weaving cloth (being nonwoven) is different from the processing method of traditional textile, it when producing, abandoned completely traditional textile the drafting aspect spinning, rove, spun yarn, winder and weave aspect warping, sizing, weave operations such as (or knitting), the shredding and the combing fore-spinning that have only retained weaving, because of but a kind of production process is short, automaticity is high, production cost is low efficient production method.Yet traditional nonwoven also has shortcoming, poor with woven fabric phase specific strength and durability, can not as woven fabric, repeatedly clean, percentage elongation is large, and resilience is poor, thereby has limited its application in clothes and some high strength fields.
Summary of the invention
Technical problem to be solved by this invention is to overcome the defect that above-mentioned prior art exists, a kind of nonwoven and production method thereof adding online through, weft yarn is provided, its production method by traditional non-woven fabric production method and woven fabric organically combines, when improving speed of production and efficiency, reducing production costs, make manufactured goods have the advantage of traditional nonwoven and woven fabric concurrently, overcome traditional nonwoven and woven fabric shortcoming separately simultaneously.
For this reason, the present invention adopts following technical scheme: a kind of non-woven fabric production method adding online through, weft yarn, it is characterized in that, the equipment of its use comprises spunlace non-woven cloth equipment, a set of feeding system of warp and a set of jet system of beating up, described spunlace non-woven cloth equipment comprises bale opener, airflow cotton feed machine, carding machine, lapping machine and the spun-laced machine of series connection successively, described carding machine has two, and described feeding system of warp is positioned at First carding machine top, by warp beam, is connected with a motor; The procedure of processing of nonwoven is as follows: first, adopt short fiber through opening bag, shredding, air-flow feeding, to become fibre web after combing successively, feeding system of warp initiatively send the surface of volume lay warp thread at above-mentioned fibre web by warp beam, the jet system of beating up is beaten up simultaneously, now warp, weft yarn produce and interweave, the fibre web of second carding machine output be layered on interweave above, weft yarn and First carding machine output fibre web, form sandwich sandwich structure, i.e. upper and lower layer fibre web and middle filling yarn; Then through water thorn stabilization zone, under High-Pressure Water effect, upper and lower layer fibre web and middle filling yarn intert mutually entwines and is tightly linked and is integrated, due to fibre web and the entanglement that interweaves between weft yarn, manufactured goods have good brute force, make the nonwoven that grammes per square metre is 40-200 gram/square meter.
That makes can high-speed production owing to not needing to carry out cross lapping with the nonwoven cloth material through, weft yarn, and powerful high, the powerful difference of vertical, horizontal is little, and cost of material is low, good springiness.
Above-mentioned non-woven fabric production method, the active warp let-off speed of feeding system of warp is 20-100 m/min, and described warp thread is long filament, and as terylene, polypropylene fibre or polyamide fibre etc., its fineness scope is 30-60D, and warp thread arrangement pitch is 2-20 root/10 centimetre.
Above-mentioned non-woven fabric production method, the jet system of beating up is by being with standoff reed, air nozzle, weft accumulator and air compressor to form, the jet speed of beating up be 400-1000 root/minute, the jet width that beats up is 3.5 meters, with the working width just coincide of nonwoven; Described weft yarn is filament yarn or spun yarn, filament yarn can be terylene, polypropylene fibre or polyamide fibre, fineness scope is 30-60D, spun yarn can be one or both the mixture in the synthetic fibers such as terylene, polyamide fibre, viscose glue, cotton fiber or natural fiber, fineness scope is that 10-60 props up, and weft yarn arrangement is spaced apart 5-50 root/10 centimetre.
The invention has the advantages that:
1, the production method of traditional non-woven fabric production method and woven fabric is combined, improving speed of production and efficiency, when reducing production costs, manufactured goods have had the advantage of traditional nonwoven and woven fabric concurrently, overcome traditional nonwoven and woven fabric shortcoming separately simultaneously, widen greatly application, there is extraordinary market application foreground.
2, can have good shape-retaining ability, washability and satellite for making wiper, clothes and wallpaper, be nonwoven cloth material of new generation.
3, the present invention adopts in nonwoven production process and adds online woven fabric with the form interweaving mutually through weft yarn, thereby can well control through weft count, it is very sparse that interval between warp thread and the interval between weft yarn can be arranged, if warp thread arrangement pitch is 5 pieces/centimetre, warp thread arrangement pitch is 2 pieces/centimetre, and under the condition of same fineness of yarn, the fabric of making is like this that existing loom can not be knitted system, otherwise can produce slippage and splitting, cannot carry out following process.Thereby manufactured goods are when possessing good brute force, are also not easy to produce splitting, greatly improved production efficiency.
4, adopt long filament as centre when the weft yarn, can further reduce production costs.As while adopting polyester filament yarn, its price is 1.2 ten thousand yuan/ton, and be 1.4 ten thousand yuan/ton for the terylene short fiber price of nonwoven, through weft yarn, greatly improved nonwoven powerful, can make nonwoven under the condition of lighter grammes per square metre, just can obtain the brute force of high grammes per square metre nonwoven, thereby greatly reduce production cost.
Below in conjunction with specification drawings and specific embodiments, the invention will be further described.
Accompanying drawing explanation
Fig. 1 is process chart of the present invention.
