Preparation method of brushing cloth for ultra-thin fastening tape

Abstract

The invention relates to a preparation method of brushing cloth for an ultra-thin fastening tape, which is characterized by comprising the steps of: applying oil and ester on 170D / 24F polyvinyl alcohol short fiber; then neatening the 170D / 24F polyvinyl alcohol short fiber with 170D / 24F nylon 6 to form a warp disc and neatening the 170D / 24F polyvinyl alcohol short fiber with 150D / 10F nylon 6 to form a wool yarn disc; weaving warp, weft yarn and wool yarn into base ribbon by a ribbon loom; dyeing the base ribbon at a temperature higher than 98 DEG C; carding and brushing looped piles by using a 35# stainless steel needle; and then coating, drying and standing to obtain the brushing cloth for the ultra-thin fastening tape. The preparation method of brushing cloth for the ultra-thin fastening tape provided by the invention has the advantages of simple process. The brushing cloth for the ultra-thin fastening tape prepared by the method provided by the invention is only 1.1+ / -0.1mm thick which is 45% of that of the brushing face of current fastening tape and is used as the brushing face of the fastening belt. The brushing cloth for the ultra-thin fastening tape peeled circularly for more than 10000 times still has good fastening force, and the brushing cloth for the ultra-thin fastening tape has a long service life compared with that of current brushing cloth for the fastening tape.

Description

technical field [0001] The invention relates to the technical field of hook and loop fasteners, in particular to a method for preparing a raised cloth for ultra-thin hook and loop fasteners. 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. The existing Velcro mainly includes nylon Velcro and polyester Velcro. The Nylon Velcro has strong fastening force and its service life c...

AI Technical Summary

Problems solved by technology

The quality of the Velcro is mainly determined by the strength of the Velcro and the number of fastening times. The existing Velcro mainly includes nylon Velcro and polyester Velcro. The Nylon Velcro has strong fastening force and its service life can reach More than 5,000 cycles of peeling, but its thickness is generally above 2.5mm, the product is relatively thick, and feels hard. The glue used for gluing is mainly polyurethane adhesive, but it needs to be diluted with acetone

Polyester hook and loop fasteners have weak fastening force and short service life. The service life is generally less than 500 cycles of stripping and the feel is poor.

The existing nylon hook and loop generally uses 170D / 12F nylon 6 as the warp yarn, 300D / 12F nylon 6 as the wool yarn, and 170D / 24F nylon 6 as the weft yarn. The warp yarn twist generally reaches 280 twists / meter during the weaving process. It can be woven, otherwise it is difficult to weave, and it is easy to break the yarn

The high twist of the warp leads to high hardness of the product, weak fastening force and poor fastening effect

Ordinary fleece cloth for hook and loop is generally more than 2.4mm in thickness. After comparison, it feels very hard and is not suitable for close-fitting use. There are also some thinner fleece cloths in the market, but the service life is short. Generally, after 150 cycles of peeling, the hair will start to be removed. , or pilling, loss of buckle force
