Problems solved by technology

[0003] As a result, many disadvantages
Therefore, in the above-mentioned positions or parts, the crimping of the yarn in weaving and the shrinkage in the subsequent process may deviate from the surface area of ​​the fabric without wrinkles, with the result that the specific technical properties in these positions cannot meet the requirements
[0004] In addition, superimposed wrinkles can impair the strength of the fabric in the aforementioned locations
[0005] In addition to this, the airbag may not be able to deploy due to the aforementioned creases, which will result in reduced airbag protection
[0006] Another disadvantage is that the tack of the film laminated to the fabric may be damaged by the irregular surface areas of the corrugated parts where the coating film that may be placed deviates from the irregular surface areas of the corrugated parts, and / or the rough seams of the coated film may be compromised
This can also lead to failure of technical performance and products and articles with the above-mentioned defects will become scrap

Embodiment Construction

[0015] see now figure 1 , which shows the interweaving of a two-ply part 2 and a four-ply part 4 in an airbag woven by methods known in the prior art in which a plain weave is used in the two parts 2 and 4 of the fabric shown Fabric L1 / 1, due to the difference in fabric sets in the two parts of the airbag woven by this method, the finished product was severely wrinkled.

[0016] see figure 2 , showing the interweaving of two-ply parts and four-ply parts in an airbag woven according to the method of the present invention. exist figure 2 In the two-layer part 12 shown on the left of figure 2 In the four-ply part 14 shown on the right, plain weave L1 / 1 is used. Produced by applying the method of the present invention such as figure 2 The fabric shown is characterized by a uniform set obtained by reducing the set of two-ply parts 12 according to the method of the invention so as to adapt it to a set of four-ply part 14 . By utilizing the method of the present invention, ...

Abstract

The invention relates to a method for weaving fabrics that comprise in at least some sections multiple layers, especially one-piece woven (OPW) airbags comprising single-layer, double-layer and multi-layer sections. According to the inventive method, weaves or weave combinations are produced in the double- or multi-layer sections that are different from the plain weave.

Description

technical field [0001] The present invention relates to a method of weaving a fabric constructed in multiple layers at least in some parts, in particular integrally woven airbags (OPW stands for integral weave) comprising interweaving upper and lower layers into a single layer at the selvage portion. Background technique [0002] When making multiple layers of woven fabric with a certain construction (such as an integrally woven (OPW) airbag), when constructing multiple parts with different numbers of fabric layers (such as with interwoven spacers, and / or using different materials and / or or different fineness), in each case the individual layers of the parts in contact with each other have different sets and cover factors, with the result that wrinkling is possible. This is because: when the existing mass of yarn material is distributed in more or less layers than before, or when coarse yarns (i.e. yarns with a greater mass) are used in the same group, The ratio of mass to ...
