Polyester fiber/silk union adhesive fastening strip and preparing technology and equipment thereof

Abstract

The present invention discloses a kind of polyester fiber and nylon interwoven self-gripping fastener tape and its production process. The working layer of said self-gripping fastener tape adopts nylon material and its base layer adopts polyester fiber material. The described self-gripping fastening layer is transversally and longitudinally alternatively distributed hooked surface structure, looped height is 1.4-1.6mm, and the described another self-gripping fastening layer is transversally and longitudinally alternatively distributed pile face structure, looped height is 2.4-2.6mm. said invention also discloses a dyeing vessel for dyeing blank tape and a hook-cutting drying device.

Description

Technical field: [0001] The invention relates to a production method of a Velcro belt, in particular to a production method of a polyester-brocade interwoven Velcro belt. Background technique: [0002] Velcro, also known as Velcro, can be widely used as bonding materials for clothes, shoes and hats, bags, sports equipment, medical equipment, etc. The hook and loop fastener is composed of the bottom layer and the working surface layer, that is, the hook and loop layer. The hook and loop layer has a hook surface and a suede surface. The production of Velcro usually needs to go through processes such as warping, weaving, dyeing, raising (suede), gluing, breaking hook (hook surface), and rolling. The indicators to measure the quality of hook and loop products are mainly quality indicators and appearance defects. The so-called quality indicators refer to the strength of the hook and loop and the number of times of fastening. determined. Therefore, the requirements for dyeing, ...

AI Technical Summary

Problems solved by technology

[0004] However, the Velcro made of all-nylon material, because the working surface and the bottom layer are all made of nylon material, its cost is relatively high

On the other hand, since the resin used for gluing all-nylon products uses ketone products as diluents, it will have an impact on the production environment, the health of employees and the atmospheric environment.

[0005] Compared with nylon material, polyester material has the advantages of low price and good moisture resistance, especially when used underwater, it has little effect on adhesion, but it also has the disadvantage of poor durability

However, due to the full polyester Velcro or polyester interwoven Velcro, it is more complicated in dyeing, gluing and other processes, and there are few mature technologies to solve it, and more are only under research and development.
