Embodiment 1

[0030] Accompanying drawing 1 is the structural schematic diagram of powder-spot coated disposable non-woven shoe cover material, the shaded part is the sole material, which is composed of a layer of powder-spot coating and a layer of non-woven fabric, which is a powder adhesive that passes through a duster. The powder dots are formed on the non-woven fabric and obtained after heating and setting, which can be circular, oval, or other irregular shapes required by the sole; the rest is non-woven fabric. The composite material is cut along the dotted line in the figure, and then a rubber band is sewn around to make a disposable non-woven shoe cover with a powder-dot-coated sole.

Embodiment 2

[0032] The width is 0.5m and the areal density is 25g / m 2 The polyethylene spunbond non-woven fabric was unwound at a speed of 100m / min and entered the duster. A controllable fixed-point duster with a vibrating screen radius of 0.1m was used, and low-density polyethylene powder was used as a binder. The residence and departure times of the receiving plate under the screen holes were 0.3 seconds and 0.12 seconds, respectively. The powder binder forms approximately circular powder dots with a spacing of 0.5 m on the longitudinal centerline of the nonwoven fabric. The above-mentioned non-woven fabric continues to enter an oven with a temperature of 95 ° C at a speed of 100 m / min, heat and shape, and coil to obtain a width of 0.5 m, a powder coating radius of 0.1 m, and the center of the coating is 0.25 m away from the edge of the non-woven fabric. The powder-dot-coated disposable non-woven shoe cover material with a spacing of 0.5m is shown in Figure 4 for the structure.

Embodiment 3

[0034] The width is 0.5m and the areal density is 25g / m 2 The polypropylene spunbond nonwoven was unwound at a speed of 5m / min into the duster. A controllable fixed-point duster with a vibrating screen radius of 0.1m was used, and low-density polyethylene powder was used as a binder. The residence and departure times of the receiving plate under the screen holes were 6 seconds and 2.4 seconds, respectively. The powder binder forms approximately circular powder dots with a spacing of 0.5 m on the longitudinal centerline of the nonwoven fabric. The above-mentioned non-woven fabric continues to enter the oven with a temperature of 95 ℃ at a speed of 5m / min, heat-setting, and coiling to obtain a width of 0.5m, a powder coating radius of 0.1m, and the center of the coating is 0.25m away from the edge of the non-woven fabric. Powder-dot-coated disposable non-woven shoe cover material with a pitch of 0.5m.

Abstract

The present invention relates to a material and preparation method of a one-off powder point coated nonwoven fabric overshoe. A sole of the material is a layer of the powder point coated nonwoven fabric and an upper is the nonwoven fabric, which are formed by thermal shaping. The preparation method of the present invention includes that firstly the on-line or unwound nonwoven fabric is put into a powdering machine; secondly the time that an accepting board at the powdering machine stays at and departs from the position below sieve pores is adjusted according to the space of the coated sole, which ensures that the powder points of the required shape are formed at the nonwoven fabric by a powder bond; thirdly the powdered nonwoven fabric is put into an oven for thermal shaping and taking up. The overshoe prepared by the material is synchronously provided with the characteristics of being air permeable, comfortable, dustproof etc. and improves the use functions of the one-off overshoe, and the preparation method of the overshoe is simple and costs little time and is fit for the industrialized production.

Description

technical field [0001] The invention relates to a disposable shoe cover material and a manufacturing method thereof, in particular to a disposable powder-dot-coated non-woven shoe cover material and a manufacturing method thereof. Background technique [0002] Disposable shoe cover is a kind of bag body which is made of plastic film or non-woven fabric, and is equipped with elastic band on the edge to make it have elastic shrinkage. Because of its good toughness, wear resistance, softness and convenience, it is widely used in computer centers, computer rooms, hotels, hospitals, family rooms and so on. However, the disposable shoe covers made of plastic film have poor air permeability, which will cause the problem of covering the feet during wearing; while the disposable shoe covers made of non-woven fabrics are breathable and comfortable, but due to the existence of microscopic particles at the bottom of the shoe covers Holes, the dust on the soles will fall to the floor wh...
