Embodiment 1

[0037] Raw materials: 82% (weight ratio) of wood pulp fluff pulp, 18% (weight ratio) of 919 glue.

[0038] Non-woven production: After air-laid to form a fiber web, the weight of the fiber web is 45GSM, dilute the 919 glue by one time, spray on one side of the fiber web, then dry, and then spray the other side, control the amount of spraying, so that the non-woven fabric Weight at 55GSM.

[0039] Liquid wipes

[0040] 1. Normal dosing 1.5 parts of EDTA

[0041] Lecithin 0.8 parts

[0042] Aloe Vera Extract 10 parts

[0043] 3 parts glycerin

[0044] 1 part lanolin

[0045] 1.2 parts of citric acid

[0046] Add 80.5 parts of deionized pure water

[0047] 2. Passivation:

[0048] boric acid 2 parts

[0049] Cut the non-woven fabric into 150*200mm slices, fold them in a Z shape first, and then fold them in half. Folded 50 pieces of non-woven fabrics were folded neatly. Soak it in the wet wipe solution, put it into a plastic bag of appropriate size, and heat seal it. ...

Embodiment 2

[0051] Raw materials: 78% (weight ratio) of viscose fiber, 22% (weight ratio) of SKJ glue.

[0052] Non-woven production: After combing into a web to form a fiber web, the weight of the fiber web is 24GSM, dilute the SKJ glue twice, spray on one side of the fiber web, then dry, and then spray the other side, control the amount of spraying, so that the non-woven fabric Weight at 28GSM.

[0053] Liquid wipes:

[0054] 1. Normal dosing 1.5 parts of EDTA

[0055] Lecithin 0.8 parts

[0056] 3 parts glycerin

[0057] 1 part lanolin

[0058] 2 parts citric acid

[0059] Add 85.7 parts of deionized pure water

[0060] 2. Passivation: 6 parts of table salt

[0061] Cut the non-woven fabric into 150*200mm slices, fold them in a Z shape first, and then fold them in half. Soak the folded piece of non-woven fabric in the solution, put it into a plastic bag of appropriate size, and heat seal it.

Embodiment 3

[0063] Raw materials: 92% (weight ratio) of PLA biodegradable polymer, 8% (weight ratio) of SKJ type glue.

[0064] Non-woven production: In the spunbond method, after the polymer is spun, it is air-laid to form a fiber web. The weight of the fiber web is 20GSM. Dilute the SKJ type glue by one time, spray on one side of the fiber web, then dry, and then spray On the other hand, control the amount of spraying so that the weight of the nonwoven fabric is 22.5GSM.

[0065] Liquid wipes:

[0066] 1. Normal dosing 1.5 parts of EDTA

[0067] Lecithin 0.8 parts

[0068] 3 parts glycerin

[0069] 1 part lanolin

[0070] 2 parts citric acid

[0071] Add 90.7 parts of deionized pure water

[0072] 2. Passivation: Calcium chloride 1 part

[0073] Cut the non-woven fabric into 150*200mm slices, fold them in a Z shape first, and then fold them in half. Soak the folded nonwoven fabric in a stack of 30 pieces in the solution, put it into a plastic bag of appropriate size, and heat se...

Abstract

The invention discloses a fully flushable and biodegradable nonwoven wet tissue and a production method thereof, belonging to the technical field of new textile materials. The completely flushable and biodegradable nonwoven fabric wet wipes include wet wipe formulations and nonwoven fabrics soaked in wet wipe formulations, and are characterized in that: the nonwoven fabrics are made of 100% biodegradable fibers The fiber web made of raw materials is bonded by a passivable water-soluble glue, and the wet wipe formulation contains 1-10% passivation by weight. The wet wipes of the invention are completely flushable and biodegradable, and can solve the problem of discarding the wet wipes in urban drainage systems.

Description

technical field [0001] The invention relates to a fully flushable and biodegradable nonwoven wet tissue and a production method thereof, belonging to the technical field of new textile materials. Background technique [0002] In the past two decades, the non-woven fabric industry has developed rapidly and technology is changing with each passing day. Non-woven fabric industrial products have entered thousands of households, especially in developed countries in Europe and the United States with high consumption levels. Dry and wet wipes, female sanitary napkins, children's diapers, etc. made of non-woven fabrics have entered people's daily life because of their low price, convenience, practicality, cleanliness and sanitation. However, the currently used non-woven fabric products, especially the wet wipes used in wet conditions, if discarded in the toilet, will block the bottom hole of the toilet, household drainage pipes and urban sewage pipe systems, which will bring inconve...
