Abstract

The invention discloses a weft bamboo-warp knitted fabric forming process, which comprises the step of knitting weft bamboo sheets with flexible fiber warps to make weft bamboo-warp knitted fabrics. The weft bamboo-warp knitted fabrics can be widely applied to producing various types of laminated bamboo composite material products, particularly producing bamboo honeycombed cores, bamboo honeycombed boards and other materials.

Description

Broadwise bamboo tricot moulding process

The invention belongs to TECHNICAL FABRIC and make the field, particularly broadwise bamboo silver becomes the moulding process of broadwise bamboo weaving fabric with one group of flexible fiber warp knit.

At present, produce used various bamboo curtain splints such as summer sleeping bamboo mat, bamboo offset plate, weave every group of spacing of used flexible yarn at least more than 60～80mm, in the middle of the bamboo offset plate of making, only play the operating procedure effect, seldom play the intensity effect, and have only not bamboo fabric continuously radially of the continuous bamboo curtain splint of broadwise, if want to make various composites and honeycomb core will be very limited in the use with bamboo curtain splint, or even impossible.How to utilize the bamboo material resource better, eliminate the big disadvantage of isolating property and with the problem of some thermoplastic matrix material intermiscibility differences, and can not satisfy the requirement of producing various bamboo matter reinforced composites with more matrix material is compound.

Purpose of the present invention: be exactly to weave with strip of sheet bamboo bar or non-wovenly become cloth by flexible fiber, thoroughly eliminate the isolating property of bamboo material and make it have two-dimensional freedom, flexible fiber and bamboo silver are born the pulling force of a direction separately, adjustment by flexible fiber can realize with various matrixes compound, and these all are that various bamboo matter reinforced composite Products Development are used and laid the foundation.

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, are cooperated with other loop-forming element by knitting needle again, yarn is woven on the broadwise bamboo silver is made into the bamboo weaving fabric; The transverse opening of broadwise bamboo weaving 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; Broadwise bamboo silver is laterally sent between the opening 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, and the traversing pad yarn of the sley point of comb plate, knitting needle descend and hook new yarn and slough old coil and wrap the bamboo silver; Fabric is pulled away to spooler simultaneously, is rolled into yardage roll.

The invention has the beneficial effects as follows that broadwise bamboo tricot is used for composite production and is highly susceptible to realizing bamboo silver interlayer, satisfy the requirement that reduces the composite cost; Be used to produce the bamboo honeycomb core product, can save the consumption of bamboo wood 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.

Claims

1. broadwise bamboo tricot moulding process is characterized in that: one group of flexible 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, are cooperated with other loop-forming element by knitting needle again, yarn is woven on the broadwise bamboo silver is made into the bamboo weaving fabric; The transverse opening of broadwise bamboo weaving 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; Broadwise bamboo silver is laterally sent between the opening 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, and the traversing pad yarn of the sley point of comb plate, knitting needle descend and hook new yarn and slough old coil and wrap the bamboo silver; Fabric is pulled away to spooler simultaneously.

2. broadwise bamboo tricot moulding process according to claim 1, it is characterized in that: flexible warp thread can be various fibers such as organic fiber, inorfil, artificial fibre and natural fabric, string and animal fiber, metal fibre and non-metallic fibers; Glass fibre, carbon fiber, aramid fiber, cotton fiber, polypropylene fibre, nylon fiber, polyester fiber, polyacrylonitrile fibre, polyethylene fiber, polyster fibre, acrylic fiber, nylon fibre or the like usable fibers for example: commonly used with inorganic glass fiber; Can be that a kind of raw material warp thread also can be the mixed yarn of two or more raw materials.
