Problems solved by technology

However, the disposable shoe cover has the following disadvantages during use: the disposable shoe cover made of plastic film has poor air permeability, especially in summer, it will seriously cover the feet, and the comfort is poor; while the disposable shoe cover made of nonwoven fabric Although the shoe cover is breathable and comfortable, due to the micropores at the bottom of the shoe cover, the dust on the sole will fall to the floor when people walk around, causing pollution to the indoor environment
[0003] In order to solve the shortcomings of existing disposable shoe covers that are airtight and prone to sweaty feet, patent ZL 200520099119.5 invented a method of directly pasting high-quality sole stickers on the soles, but the sole stickers must have suitable adhesive strength and poor dust resistance.

Embodiment 1

[0022] Accompanying drawing 1 is the structural representation of disposable composite shoe cover material, and shaded part is sole material, is formed by plastic film and non-woven fabric compound, and it can be the circular shape that sole needs, ellipse or other irregular shape; The rest are nonwovens. Cut the composite material along the dotted line in the figure, and then sew rubber bands around it to make a disposable composite shoe cover whose bottom is made of plastic film and non-woven fabric, and the upper is made of non-woven fabric.

Embodiment 2

[0024] The polypropylene film that width is 1m is unrolled with the speed of 5m / min, is cut into two circular composite film soles through two circular cutters of 0.08m at the distance of each 0.25m from two edges of the film. Adjust the falling speed of the cutter so that the distance between the front and rear two film soles is 0.5m, and the structure of the gained film is as shown in Figure 3.

[0025] The polypropylene spun-bonded non-woven fabric with a width of 1m enters the composite device at a speed of 5m / min. In the ultrasonic bonding composite device, the circular plastic film and the non-woven fabric are composited and wound up to become a one-time composite. For the shoe cover material, the excess plastic film is peeled off and rolled up as scraps.

Embodiment 3

[0027] Unwind a polypropylene film with a width of 1m at a speed of 20m / min, and cut it into an elliptical composite film at a distance of 0.25m from the two edges of the film through an oval cutter with a major axis of 0.2m and a focal length of 0.1m soles. Adjust the falling speed of the cutter so that the distance between the front and back two film soles is 0.5m, and the structure of the gained film is as shown in Figure 1.

[0028] The polypropylene spunbonded nonwoven fabric with a width of 1m enters the composite device at a speed of 20m / min. In the ultrasonic bonding composite device, the oval plastic film and the nonwoven fabric are composited and wound up to become a one-time composite. For the shoe cover material, the excess plastic film is peeled off and rolled up as scraps.

Abstract

The present invention relates to a material and preparation method of a one-off composite overshoe. A sole is compounded by a layer of plastic film and a layer of nonwoven fabric, and an upper is the composite structure of the nonwoven fabric. The preparation of the overshoe includes that firstly the on-line or unwound plastic film is cut and shaped by a cutting tool and is put into a compound device; secondly the on-line or unwound nonwoven fabric is put into the compound device at the same speed; thirdly the plastic film and the nonwoven fabric are compounded and taken up inside the compound device by the agglutinating technology, and the composite overshoe material is obtained. The present invention is air permeable and dustproof and hardly causes sweaty feet, and the preparation method of the present invention is simple and costs little time and is fit for the industrialized production.

Description

technical field [0001] The invention belongs to a disposable shoe cover material and a preparation method thereof, in particular to a disposable composite shoe cover material made of plastic film and non-woven fabric and a preparation method thereof. Background technique [0002] Disposable shoe cover is a bag made of plastic film or non-woven fabric, with an elastic band on the edge to make it have an elastic shrinkage mouth. Because of its good toughness, wear resistance, softness, and easy use, it is widely used in computer centers, computer rooms, hotels, hospitals, and family rooms. However, the disposable shoe cover has the following disadvantages during use: the disposable shoe cover made of plastic film has poor air permeability, especially in summer, it will seriously cover the feet, and the comfort is poor; while the disposable shoe cover made of nonwoven fabric Although the shoe cover has good air permeability and comfort, due to the micropores at the bottom of t...
