Degradable fastening tape and manufacturing method thereof

Abstract

The invention relates to a degradable fastening tape, characterized in that: the fastening tape comprises a velvety surface belt formed by weaving 60-75% of polyvinyl alcohol short fiber, 24-40% of nylon 6 long fiber and 0-1% of polypropylene long fiber, and a folded surface belt formed by weaving 60-75% of polyvinyl alcohol short fiber, 24-40% of nylon 66 long fiber and 0-1% of polypropylene long fiber, wherein the percent represents weight percent. The manufacturing method of the degradable fastening tape comprises the following steps: A, adding 80 to 100 parts by weight of water and 6 to 10 parts by weight of polyvinyl alcohol into a steam-type reaction kettle at room temperature in order to prepare adhesive; B, weaving a velvety surface blank belt by using the polyvinyl alcohol short fiber, the nylon 6 long fiber and the polypropylene long fiber; C, raising and glue-applying the velvety surface blank belt to obtain the velvety surface belt; D, weaving a folded surface blank belt by using the polyvinyl alcohol short fiber, the nylon 66 long fiber and the polypropylene long fiber; and E, glue-applying and fold-cutting the folded surface blank belt to obtain the folded surface belt. The degradable fastening tape has the advantages of good environmental friendliness, convenient degradation and recyclability.

Description

technical field [0001] The invention relates to the field of Velcro technology, in particular to a degradable Velcro and a manufacturing method thereof. Background technique [0002] Velcro, also known as Velcro, can be widely used in clothing, clothing, luggage, sports equipment, medical equipment and other products. The hook and loop fastener includes a hook surface strip and a suede surface strip, and the hook surface strip and the suede surface strip can be bonded to play the role of a zipper, which is very convenient and fast to use. The production method of the hook and loop fastener usually needs processes such as warping, weaving, dyeing, raising, gluing, breaking hooks, and rolling. The quality of the Velcro is mainly determined by the strength of the Velcro and the number of fastening times. As long as the existing Velcro is all nylon products, the glue used for gluing is mainly polyurethane resin, usually acetone is used as a diluent , easy to volatilize, and ca...
