Abstract

The invention discloses a warp-wise laying warp-knitting wood fabric molding process; the warp-wise wood fabric is formed by weaving warp-wise wood strips and flexible fiber warp yarns and weft yarns and can be widely applied to producing various wood-sandwich composite material products, in particular for wood honeycomb cores and wood honeycomb plates and the like.

Description

Warp-wise laying warp-knitting wood fabric molding process

The invention belongs to TECHNICAL FABRIC and make the field, particularly one group of wood warp-wise bar and flexible fiber are woven into warp-wise laying through compiling the moulding process of wooden fabric.

At present, the wood grows amount is big, is one of unique in the world reproducible four big materials, and tradition is to use log, and utilization ratio is low.What the modern times used in a large number is the wood-base fibre and particle panel material product, and the used wood raw material of these wood-base fibre and particle panel materials all has nothing in common with each other, the rotary-cut of glued board class, slicing veneer, the used for shaving board wood shavings, the fibre board use fiber, core-board is fast with veneer and wood, and the fast finger of various wood is integrated timber or the like.It is the directional fiber product that product has integrated timber, ply building blocks, glued laminated wood, Laminated timber, reorganization wood etc.And core-board, glued board, shaving board, oriented wood chipboard, fiberboard etc. are directed not serious product, wherein shaving board, oriented wood chipboard, fiberboard and core-board etc. have destroyed the fibre structure of timber, structural strength reduces greatly, will be it very difficult in many applications as structural material.Product all is real core, and the density of shaving board and fiberboard is also greater than timber, and the timber utilization rate of integrated timber, glued board and core-board is not high.And the same design feature of some wood materials directional fiber product with each diversity with timber and veneer, strength parallel to grain is big, isolating property is big, if directly this does not satisfy the requirements in the use as the wooden reinforced composite of reinforcing material manufacturing and various cellular material with it.Remove fiberboard and wood shavings class sheet material and realize producing continuously, other products all is modular heat pressing process production, inefficiency.

Purpose of the present invention is exactly in order to overcome above-mentioned shortcoming, be made into wooden braided fabric by flexible fiber and strip of sheet batten, thoroughly reduce the big disadvantage of isolating property of wood materials, flexible fiber and wood chip bar are born the pulling force of a direction separately, can fold arbitrarily along batten sheet direction, two-dimensional freedom is arranged, and vertical batten direction batten sheet has certain radius of gyration, and therefore wooden braided fabric has two-dimentional multiple degrees of freedom.Adjustment by flexible fiber can realize with various matrixes compound, and these all are that various wooden reinforced composite Products Development are used and laid the foundation.Produce and lay the foundation in particular for wooden honeycomb core, wooden honeycomb core composite Materials Design.

The present invention solves technology side that its technical problem adopts by being: one group of warp thread is drawn from one group of bobbin or through axle; Each root warp thread is by tensioner, and spider watcher etc. are finished the yarn pad to knitting needle by sley point, is cooperated with other loop-forming element by knitting needle again, yarn is woven on the broadwise lining yarn is made into radially wooden braided fabric; The transverse opening of warp-wise wood braided fabric by forming by the needle plate of forming through density of design and comb plate that corresponding sley point is formed by latch needles; One group of wood is drawn and is passed the broadwise stop through density and enter opening by what equate from beam of a loom through bar; Bar slit, knitting needle corresponding wood footpath, two broadwise lining yarns are laterally sent between wood two openings that directly the bar plane separates when knitting needle is in extreme lower position, catch together by the old coil on the knitting needle and the ew line of sley point, knitting needle rises to move back and encloses the top, the traversing pad yarn of the sley point of comb plate, knitting needle descend and to hook new yarn and slough old coil and wrap two lining yarns; Entangle two stuffer wefts with every wooden directly two Geju City coils of bar both sides and wrap wood footpath bar, realized that radially inlaid thread is through compiling the moulding of wooden fabric; Fabric is pulled away to spooler simultaneously.

The invention has the beneficial effects as follows that radially inlaid thread is used for composite production and is highly susceptible to realizing batten sheet interlayer through compiling wooden fabric, satisfies the requirement that reduces the composite cost; Be used to produce the Wooden honeycomb core product, can save wood usage amount widely; Be used for that curved surface individual layer ventilating structure is compound not to need processing, improved the economic benefit and the social benefit that are realized in the operating efficiency of composite production and the product use greatly.
