Abstract

The invention discloses a technique for weaving air bag restraint system (ABRS) fabric, which comprises only four steps as follows: a) beam-warping; b) water-jet looms weaving; c) setting; and d) checking of finished products. The warp can be weaved without sizing, and the rotation speed can be above 900 RPM while the maximum rotation speed of a rapier looms is 510RPM in the prior art. The water jetted by the water-jet looms in the weaving process has a self-cleaning effect on cloth cover, so that a procedure of hot-water washing and dirty removing can be avoided. Therefore, compared with therapier loom, the water-jet looms can greatly shorten processes and improve manufacturing capacity due to the above advantages. All yarns are immersed into water when the fabric is weaved by the water-jet looms, and the volume thereof is increased due to wicking and swelling, so that interweaving of warp and weft of the fabric is much closer after battening, thus improving the performance of smaller needle fleece of the finished product fabric to achieve the purpose of improving defects in current rapier weaving.

Description

A kind of weaving process of air bag lining

Technical field

The present invention relates to a kind of weaving process of air bag lining.

Background technology

In recent years along with the develop rapidly of automobile industry, also emerge rapidly as the air bag product of automobile passive safety system, particularly at home as a kind of emerging strong footpath of rising industry growth momentum thereupon.But the air bag product is because the starting of making at home is late, and technology weakness, and the technical requirement strictness of this safety member are so running into a lot of bottlenecks aspect the production of product.The weaving process of lining particularly, the improper performance indications of product that all can cause of a lot of weaving process do not reach, weaving process abroad mainly is to weave with Rapier looms at present, it is relatively poor that but the anti-pin of the woven lining of arrow shaft is grabbed strength character, static air permeability and coefficient of friction are generally also higher, this all is more disadvantageous factor in the blasting process of airbag, and the production efficiency of Rapier looms is lower, warp thread will just can be weaved after starching is handled on the one hand, the slurry of cloth cover also will be handled through destarch and hot water wash more on the other hand, long flow path has influenced the making production capacity of product greatly.The technological process of prior art as shown in Figure 1: warp thread is the process warping earlier, and then does the pulping axle through the starching processing, is merged into beam of a loom to the warp rebeaming machine platform; Then could arrive on the loom and weave cotton cloth, the rotating speed of loom generally can only be about 450RPM; Carry out destarch to desizing machine again behind the cropping, dispose on the cloth cover slurry and and dirty; Last shaping and drying is to finished product inspection.

Summary of the invention

At the deficiencies in the prior art part, the invention provides provide a kind of and have industrial value, be convenient to produce, meet safety standard, cost is lower, can add the novel air bag face weave technology of producing extensively production capacity and enhancing product performance.

For achieving the above object, technical solution of the present invention is:

A kind of weaving process of air bag lining, its processing step is as follows:

A) warping: under the 400-500m/min speed of beaming, be wound on the former silk thread cake of some on the beam of a loom uniformly by warping machines;

B) water jet looms is weaved cotton cloth: under the loom rotating speed more than the 600rpm, weft yarn the moving up and down of warp thread on beating motion by reed and heald frame after the traction of water under high pressure makes through weft yarn to interweave mutually;

C) typing: under 40～65m/min speed, 130-200 ℃ temperature, cloth is in baking oven HEAT SETTING about 1min time;

D) finished product inspection: the outward appearance and the service check that carry out finished product by technological requirement.

The usefulness of technique scheme is:

Significantly improved the pin of lining grabs intensity, has reduced static air permeability and skin-friction coefficient according to the made air bag lining of weaving process of the present invention.This is produced, and the weaving process flow process is simple and easy, cost is lower, superior performance, and the industrial value height helps the demand of growing automobile industry to airbag safety spare.

Description of drawings

Fig. 1 is the prior art processes schematic flow sheet;

Fig. 2 is a process flow diagram of the present invention.

The specific embodiment

The present invention now is described in conjunction with the accompanying drawings and embodiments.

The air bag lining adopts a kind of novel water jet looms to weave, and warp thread can just can be weaved without starching, and rotating speed can reach more than the 900RPM, and about the highest 510RPM of rotating speed of the Rapier looms of prior art.And the water that this water jet looms ejects in weaving process can reach self-cleaning effect to cloth cover, so can remove dirty operation through one hot water wash again, so water jet looms can shorten flow process greatly because of the relative Rapier looms of above advantage is arranged, and improves and makes production capacity.Cloth all is dipped into water at yarn when water jet looms is weaved, and it is big that yarn water absorption and swelling volume becomes, and it is more tight to interweave at the longitude and latitude that makes lining after beating up, and grabs less performance thereby can improve lining finished product pin.Reach the woven defective of the present arrow shaft of improvement with this.

Process chart as shown in Figure 2 as seen, as long as flow process of the present invention is through 4 steps, that is, a) warping, b) water jet looms is weaved cotton cloth, c) typing, d) finished product inspection.

Below 4 processing steps are elaborated:

A) warping: under the 400-500m/min speed of beaming, by warping machines the former silk thread cake of some is wound on beam of a loom uniformly and exists.Beam of a loom need meet density, hardness, tension force and warping bar and count requirement, satisfies condition for the back segment working procedure processing provides.

B) water jet looms is weaved cotton cloth: under the loom rotating speed more than the 600rpm, weft yarn the moving up and down of warp thread on beating motion by reed and heald frame after the traction of water under high pressure, make through weft yarn to interweave mutually, be made into the cloth of the institutional framework of corresponding requirements, arrange regularly with certain space through weft yarn.

C) typing: under 40～65m/min speed, 130-200 ℃ temperature, under certain setting fabric width, certain force of strain condition, cloth makes cloth dimensionally stable, good air permeability in baking oven HEAT SETTING about 1min time.

D) finished product inspection: the outward appearance and the service check that carry out finished product by technological requirement.
