Abstract

The invention discloses a manufacturing method of a sulphur resistant Velcro, including procedures as follows: the Velcro is put into a tincture machine to be cleaned, then the Velcro is bleached; and then the bleached Velcro is dehydrated by a hydroextractor, and is friezed by a friezing machine; then the bleached and friezed Velcro undergoes sulphur resistant treatment and gum with a gum machine, and finally is dried by baking. When the sulphur resistant Velcro manufactured by the method of the invention is used as a Velcro for products such as rubber products, the Velcro can not turn yellow, which is caused by the sulphur contained gas released during the processing process of the rubber products; therefore, the utility model has the characteristics of beautiful appearance and durable use.

Description

1. Technical field: [0001] The invention relates to a processing method for a buckle, in particular to a method for manufacturing a sulfur-resistant nylon hook and loop. 2. Background technology: [0002] When the existing ordinary nylon hook and loop is used for the hook and loop of rubber products, because the gas released during the processing of rubber products contains sulfur, the nylon hook and loop will turn yellow, which will seriously affect the appearance and durability of the hook and loop . 3. Contents of the invention: [0003] Aiming at the defects in the prior art, the invention provides a method for manufacturing sulfur-resistant nylon Velcro. After the nylon Velcro is subjected to sulfur-resistant treatment by the method of the present invention, the nylon Velcro produced has the property of not changing color. And beautiful, durable features. [0004] The manufacturing method of the sulfur-resistant nylon Velcro provided by the present invention is to f...
