Abstract
The present invention relates to a making method for a long fibre net knitting device and long fibre non-woven fabric, which comprises: the long fibre is taken as raw material and is knitted into a fibre net through the long fibre net knitting device; the long fibre non-woven fabric is obtained through consolidating the formed fibre net. The method of the present invention omits an extruding machine and a spinning system of the non-woven fabric creating process in a common spun-bond method, and omits a cotton opening process, a cotton carding process and a cotton stacking process of a traditional short fibre creating process. Therefore, the method of the present invention has simple creating process. Because material selection is variegated, the method of the present invention has wide application range.
Description
The fine manufacture method that becomes net arrangement and long fiber non-woven cloth is grown about a kind of by the present invention system, refers to especially a kind ofly can simplify conventional process, and can be applied to make the method for the long fiber non-woven cloth of diversified product.
On the known techniques, the method that long fiber is made Nonwovens is mainly spun-bond process (spun-bonding), as Fig. 1 (with reference to Fiber producer/1984, February, the 38-41 page or leaf, Spunlaid Fabrics Broadening their horizons in Europe) shown in, its processing procedure binds and closes melt spinning and air lay device to make the long fiber Nonwovens, is a kind of method of directly spinning.Know clearly it, the spun-bond process processing procedure is included in the thermoplastic plastic's raw material of packing in the hopper 1, this raw material is through extruder 2 dissolvings, raw material after the dissolving is delivered to spinning plate 4 and is squeezed into thicker fiber 5 after measuring pump 3 meterings are got, and then extends refinement through air nozzle 7, rapid cooling air 6 is cooled to thinner fiber, and the suction of mat air intake device 8 is adsorbed on into fiber and becomes web 10 on the net conveyer belt 9, through fixed engineering 11 solid works, batches spunbond Nonwovens 12 with coiling machine then again.Because whole processing procedure is complicated, the equipment investment amount of money is huge, utilizes air-flow to extend fiber again, and product elasticity is little, and the higher shortcoming of cost is arranged.
The another kind of known method of making Nonwovens with staple fibre is comb and parallel cotton fibers prior to spinning method (carding), as shown in Figure 2, the system utilize staple fibre 13 through opener 14 with fabric thrashing, through cotton feeder 15 fiber basis weight is fed carding machine 16 again, after making concordantization of fiber, deliver to folded cotton machine 17 and build up the thickness that needs, deliver to needle rolling machine 18 again and roll into Nonwovens.The structure of the Nonwovens of making thus is comparatively bulk, but it is low to have intensity, and degree of stretching height easily spreads the shortcoming of splitting.Therefore, this kind Nonwovens usually needs further by adding the reinforcement material or selecting for use mode such as high-tenacity fiber to improve fibrous physical property.
United States Patent (USP) discloses a kind of device by continuous fibers manufacturing Nonwovens fabric for No. 4999080, and this device also utilizes the design of known spun-bond process, and wherein the spunbond processing procedure by melt spinning and extension reaches the purpose of making the Nonwovens product.
United States Patent (USP) discloses the method that a kind of formation has the nonwoven fabric of excellent uniformity No. 5225018, and the method comprises the phase I of separating fibre bundle with high-speed air flow, and static is opened fine to reach the second stage that fiber evenly separates.This patent mainly ties up to and comprises a static in the device and open fine member, but still does not take off the scope of the spunbond processing procedure of melt spinning.
United States Patent (USP) discloses a kind of device of making nonwoven fabric No. 5108276, and principal character is the design of nozzle, comprises two spinning bundles of single composition or biconstitutent fibre in the processing procedure.The processing procedure of this patent is that the conventional spunbond processing procedure is improved, but still belongs to the spunbond processing procedure of melt spinning.
The present invention system is improved at stating shortcoming on the prior art, and a kind of simplification processing procedure is provided, and reduces cost, and improves the manufacture method of the long fiber non-woven cloth of product diversity and quality.
The present invention's purpose is to provide a kind of long fine one-tenth net arrangement, comprises wire feed roller, air nozzle, conveyer belt and air draught member.
Another object of the present invention is to provide a kind of manufacture method of long fiber non-woven cloth, comprises that the long fiber spinning cake that makes as raw material forms long fibre net via long fine one-tenth net arrangement, and the long fibre net that is formed is again through fixed engineering, and formation long fiber Nonwovens.
