Abstract
The said safe air bag has two layers of fabric with different structure, specification and air permeability and it has excellent performance and small folded volume. The working apparatus is multiple box loom or xiphoid loom with electronic multiple-arm split mechanism and double-shaft automatic warp-feeding mechanism.
Description
The present invention relates to field of textiles, especially the processing method of non-coating full forming type safe air bag fabric and equipment thereof.
During air bag work, one deck fabric is towards the driver and conductor, and another layer deviates from the driver and conductor.Usually, have less air penetrability, make less this layer fabric that see through of working gas in the air bag directly flow to the driver and conductor, reduce the injury of human body towards one deck of driver and conductor; And the air penetrability of another layer is bigger, makes that working gas filters rapidly in the capsule, loss.At present use the disadvantage of coating type gas cell fabric many in the world, so adopt non-coating type safe air bag fabric more, it has two kinds of stitched type and full forming types, and the stitched type safe air bag fabric is by two-layer different size, structure, and the fabric that respectively has required different air penetrabilities is sewed up and formed.And the shortcoming of stitched type safe air bag fabric is that the joining edge thickness around (1) air bag is big, is difficult for folding, and volume after folding is bigger; (2) the sewing material of tape edge and sewing technology are bad all around is the unsafe factor that causes the air bag work mistake.Full forming type safe air bag fabric such as Fig. 1 show that capsule body A is two-layer plain weave fabric, and the upper strata deviates from the driver and conductor towards driver and conductor lower floor, and their systems of once knitting simultaneously on loom form.The two-layer fabrics of capsule body A is linked together by edge sealing B, C simultaneously, thus the harmfulness that it has avoided air bag stitching processing all around to be brought.Also the fabric thickness owing to edge sealing is little, so the full forming type safe air bag fabric volume after folding is less, is the technological development direction of safe air bag fabric.
According to patent WO 92/20847, existing full forming type gas cell fabric changes a certain regional air penetrability in two-layer fabrics or the fabric by changing plain weave pattern point position.Obviously to improving the gas barrier properties of non-coating safe air bag fabric, it is still very unfavorable to reduce its volume and weight.
The objective of the invention is to propose a kind of processing method and equipment thereof of non-coating full forming type safe air bag fabric.
Its equipment of characteristics of the present invention is by the dobby shedding mechanism of monolithic computer control shedding order and the multi-shuttle box mechanism of computer control, also can use rapier weft inserting mechanism and twin shaft active type to regulate warp-feeding mechanism automatically combines, its processing method be on this process equipment, take through, the special number difference of weft yarn, warp, the twist difference of weft yarn, the warp count difference, the two-layer air bag capsule body A with different air penetrability of non-coating full forming type is processed in the identical and combination of weft count, and the left and right sides edge sealing B of air bag capsule body A and last lower sealing edge C be individual layer reed mat twill-weave, and the two-layer fabrics of capsule body A is by edge sealing B, C links together.
The present invention finishes harness motion with 12 pages of heald frames of dobby shedding organization management of existing monolithic computer control shedding order.According to gas cell fabric appearance and size and to the requirement of fabric breathability, should be to fabric tissue through, weft yarn period R

Jl=160～200/10cm.
Use the multi-shuttle box mechanism of existing computer control, also can use rapier weft inserting mechanism, following two purposes are arranged, the first: it is woven that capsule body A goes up lower sealing edge C, and the warp count of fabric equals P
JhWith P
JlSum, for avoiding the edge sealing fabric fine and close difficulty of beating up, the fabric tissue of edge sealing such as Fig. 2 (b) should be different with fabric tissue such as Fig. 2 (a) of capsule body, and the former average float is bigger than the latter.In addition, the weft count P ' of fabric
wAlso to be reduced to and equal P

Wl), use multi-shuttle box mechanism, taking the ratio of real latitude (introducing weft yarn) number of times and empty latitude (not introducing weft yarn) number of times is 2: 2, just can reach to reduce P '
wPurpose.It two is: according to the capsule body A requirement of two-layer fabrics air penetrability difference up and down, adopt multi-shuttle box mechanism can introduce the weft yarn of two kinds of special numbers of difference, the different twists to the two-layer fabrics of capsule body A.As the weft yarn of introducing the upper strata is 420～600d, and filling twist is non-twist, and the weft yarn of introducing lower floor is 300～420d, and filling twist is 0～200 sth. made by twisting/m.
It is to realize that the two-layer fabrics of capsule body A has the another key problem in technology of different size structure, different air penetrabilities that the twin shaft active type that the present invention adopts is regulated warp-feeding mechanism automatically, and the warp thread that forms two-layer fabrics is respectively sent from two different beams of a loom separately energetically.Be wound on two warp thread on the beam of a loom and have different special numbers, the different twists.As the warp thread that the beam of a loom that is used for knitting system capsule body A upper layer of fabric is reeled is 420～600d, and warp twist is non-twist, and knitting the warp thread of reeling in the beam of a loom of system capsule body A layer fabric is 300～420d, and warp twist is 0～200 sth. made by twisting/m.
Because introduce the special number difference of warp, weft yarn of capsule body A levels fabric, twist difference, and the warp count difference of capsule body A levels fabric, so this two-layer fabrics has different fabric specifications, structure, and then the fabric air-permeability rate is also different.
Twin shaft active type of the present invention is regulated warp-feeding mechanism automatically, and it is combined by two cover warp-feeding mechanisms arranged side by side, sees Fig. 3.One cover is to adopt the active type of existing technology 1511S-110 (1 * 4) box-loom to regulate warp-feeding mechanism automatically, shown in the figure right side is divided, this mechanism with the swing of the right lay sword 1 of loom as let-off motion power; Use manual type, acting force arm length by changing tension weight 2 (1) and tension weight quality control beam of a loom 3 (1) the tension force of the warp thread of sending 4 (1); The back rest 5 (1) is as the tension force sensing element of warp thread 4 (1), and the warp run-in of beam of a loom 3 (1) is automatically adjusted, and makes warp tension keep constant.The another set of active type of then having transplanted existing technology K251 silk loom is regulated warp-feeding mechanism automatically, shown in the figure left part, it with the swing of loom left side lay sword 6 (projection of left and right lay sword overlaps) as let-off motion power; Be with manual type equally, acting force arm length by changing weight 2 (2) and tension weight quality control beam of a loom 3 (2) the tension force of the warp thread of sending 4 (2); The back rest 5 (2) and press support roller 7 respectively as the sensing element of the diameter of the tension force of warp thread 4 (2) and beam of a loom 3 (2) automatically adjusts to the warp run-in of beam of a loom 4 (2), makes warp tension keep constant.Warp thread 4 (2) is through before being sent to machine behind the fixing lease rods 8,9,10,11, and before warp thread 4 (1) passed through fixedly and to be sent to machine behind the lease rods 12,13, warp thread 4 (1), 4 (2) entered the shed open zone after converging.
Advantage of the present invention is: the two-layer fabrics of (1) capsule body has different air penetrability, and the serviceability of full forming type safe air bag is improved greatly; (2) safe air bag fabric security performance height is easy to fold, volume is less; (3) eliminated the processing of the stitching around the air bag, avoided sewing material and the bad unsafe factor that causes the air bag work mistake of sewing technology; (4) employed loom equipment all is that prior art is fairly simple, is beneficial to popularization; (5) with low cost.
