Abstract
Description
Technical Field
[0001] This utility model relates to the field of shoulder strap technology, and in particular to a silicone-bonded micro-elastic shoulder strap of different thicknesses. Background Technology
[0002] Shoulder straps, also called shoulder garments, once referred to the clothing of the Greeks. In modern times, they are part of clothing. Shoulder garments were clothing worn by the Greeks in the sixth century BC. They were strips of cloth woven from wool or linen, with one end hanging down from the left shoulder and the rest going around to the back, turning from under the right armpit to the front, and then hanging down from the left shoulder, with the other end hanging down at the back.
[0003] Existing shoulder straps have low adhesion strength and are prone to separation after repeated washing. This invention can effectively increase the adhesion strength of shoulder straps. Utility Model Content
[0004] The purpose of this invention is to provide a silicone-bonded micro-elastic shoulder strap of different thicknesses, thereby solving the problem of low adhesion strength of the shoulder strap.
[0005] To achieve the above objectives, a silicone-bonded micro-elastic shoulder strap of varying thickness is provided, comprising: a base layer and a foam intermediate layer, wherein a second adhesive layer is coated on the lower surface of the foam intermediate layer, a hot melt adhesive film is adhered to the lower surface of the second adhesive layer, and hook and loop fasteners are adhered to the lower surface of the hot melt adhesive film, which can effectively increase the bonding strength between the hook and loop fasteners and the foam intermediate layer and improve product quality.
[0006] According to the aforementioned silicone-bonded micro-elastic shoulder strap of different thicknesses, the lower surface of the base layer is coated with a first adhesive layer, and the lower surface of the first adhesive layer is bonded to the upper surface of the foam intermediate layer, forming a flexible buffer layer through the foam intermediate layer.
[0007] According to the aforementioned method of silicone bonding micro-elastic shoulder straps of different thicknesses, both the first adhesive layer and the second adhesive layer are PUR adhesive. A layer of PUR adhesive is applied by a PUR bonding machine to facilitate bonding.
[0008] According to the aforementioned method of using silicone to bond micro-elastic shoulder straps of different thicknesses, the base layer is a silicone layer.
[0009] According to the aforementioned silicone-bonded micro-elastic shoulder straps of varying thicknesses, the hook-and-loop fabric fleece surface is softer and more comfortable to use.
[0010] The above solution has the following benefits: applying a layer of PUR adhesive using a PUR laminating machine and then backing it with hot melt adhesive film can effectively increase the bonding strength between the hook and loop fastener and the foam interlayer, thereby improving product quality.
[0011] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0020] Reference Figure 1-4 This utility model embodiment provides a silicone-bonded micro-elastic shoulder strap of different thicknesses, comprising: a base layer 1 and a foam intermediate layer 3. The lower surface of the foam intermediate layer 3 is coated with a second adhesive layer 4. A hot melt adhesive film 5 is adhered to the lower surface of the second adhesive layer 4. A hook and loop fastener 6 is adhered to the lower surface of the hot melt adhesive film 5. The second adhesive layer 4 and the hot melt adhesive film 5 can increase the bonding strength between the foam intermediate layer 3 and the hook and loop fastener 6.
[0021] The lower surface of the base layer 1 is coated with a first adhesive layer 2, and the lower surface of the first adhesive layer 2 is bonded to the upper surface of the foam intermediate layer 3.
[0022] Both the first adhesive layer 2 and the second adhesive layer 4 are made of PUR adhesive.
[0023] Base layer 1 is a silicone layer, which is used to provide support.
[0024] Hook and loop fasteners with a softer fleece side can be made from soft materials such as nylon or cotton.
[0025] Working principle: First, the foam intermediate layer 3 is bonded to the base layer 1 through the first adhesive layer 2. Then, the hook and loop fastener 6 is bonded to the foam intermediate layer 3 using the second adhesive layer 4 and the hot melt adhesive film 5. This can effectively increase the bonding strength of the hook and loop fastener 6 to the foam intermediate layer 3.
[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
