UA80225C2 - Woven welt strip - Google Patents

Abstract

Woven welt strip is proposed, with cotton yarn in warp and polyamide threads in weft. Structure of strip is made by interweaving on the wrap of broken reinforced serge 2/2, this consists of two parts, in left part diagonals of twill weave are directed from left to right, and in right part -from right to left, there warp threads have only twin and single overlap and form strong and stable structure. At that ratio of linear density of warp thread (tex) and linear density of weft threads is within 2.1:1, and ratio of density of weft threads per 1 cm and linear density of warp threads is 1:4.1.

Description

Description of the invention

The invention relates to textile and haberdashery products for household use and can be used as a structural element in the manufacture of shoes or as an independent product.

The technical solution of the structure of the belt woven tape is known. The tape contains synthetic complex main and weft threads and drawing threads made of high-volume polyacrylonitrile yarn with a linear density of 31 tex xg.

This tape cannot be used as a structural material in the manufacture of shoes, as the structure of the tape does not provide adhesive properties and consists entirely of synthetic threads.

The closest in terms of technical essence, purpose and final result is shoe edging tape |2). The tape consists of a welt and fastening part, the weft of which is made of cotton yarn, the basis for the welt part consists of synthetic threads. The tape is interlaced with the surface covering with basic synthetic threads, which do not have good adhesive properties and do not ensure the strength of the connection of the shoe parts.

The basis of the invention is the task of creating a tape structure that has good adhesive properties and ensures the necessary strength of the connection between the top and the bottom of the shoe.

The specified goal is achieved by the fact that the woven welt tape, which is claimed, contains the main cotton threads and weft polyamide threads connected to each other, the ratio of the weave on the base is equal to four threads, the tape is made from one base on four straps, in the tooth of the berd along the background 8 threads.

The structure of the welt tape is woven on the basis of broken reinforced twill 2/2.

This weave consists of two parts, in the left part the diagonals of the twill weave are directed from left to right, and in the right part - from right to left. At the border of the weaving parts, the diagonals are shifted relative to each other so that the weft overlaps of one part border the main overlaps of the other part. p 29 Thanks to this, a clearer border between the interweaving of individual parts is obtained, and the transition section does not have long Ge) overlaps. When using this weave, a woven pattern is formed on the tape in the form of longitudinal strips, which differ from each other in the direction of the twill diagonals.

Figure 1 shows a diagram of the structure of a woven welt tape.

The warp threads 1 and the weft threads 2 have only double and single overlaps, which creates a strong and resistant structure to the relative displacement of both the main and weft threads, which provides the necessary strength of the product. Ha

Good adhesive properties of the tape are provided by the cotton yarn of the base, which interacts with the glue, which creates the necessary strength of the connection between the top and the bottom of the shoe. high school

Fig. 2 shows a pattern of interweaving and Fig. 3 is a cross-section of the tape, from which it can be seen that the first thread (from the third weft threads pass alternately under two (one) main threads, then above two (one) main threads, the second and fourth weft threads are located in the opposite direction, go around the two main threads and pass under the two main threads.

Figure 3 shows a longitudinal section of the tape, where each main thread is interwoven with the weft threads through two threads with a shift to the right by one thread. This arrangement of the main and weft threads provides "the formation of the weave of broken reinforced twill 2/2 and creates the necessary strength and density of the product. C 70 During the production of the tape, the warp threads are subjected to the greatest load in the longitudinal direction, so the ratio of the linear density (tex) of the main threads to the linear density of the weft threads is in

From" within 2.1:1, and the ratio of the density of the weft threads per 1 cm to the density of the main threads per 1 cm is 1:4.1, which ensures the necessary density of the product.

The linear filling of the tape with fibrous material on the base is 20795, and on the weft - 7295, the surface filling of the tape with fibrous material is 130905. The width of the tape depends on the type of footwear for which it is intended. aw! The developed woven welt tape is produced in production conditions on a shuttleless tape weaving equipment. o Sources of information: ka 20 1. USSR.

Claims (2)

The formula of the invention GF) 1. Woven welt tape with cotton yarn in the base and polyamide threads in the weft, which is distinguished by the fact that the structure of the tape is made by weaving on the basis of broken reinforced twill 2/2, consisting of two parts, in the left part of the diagonal of the twill the weaves are directed from left to right, in the right part - from right to left, where the main threads have only double and single overlaps and create a strong and stable 60 structure. 2. Tape according to claim 1, which differs in that the ratio of the linear density of the main threads (tex) to the linear density of the weft threads is within 2.1:1, and the ratio of the density of the weft threads per 1 cm and the linear density of the main threads is 1:41. b5
