Problems solved by technology

However, this water-soluble film also has disadvantages. It needs mold casting, blow molding, extrusion or inflation extrusion, which is inconvenient to process, and the thickness is very thin, and the mechanical strength is not enough. It is easy to be damaged during transportation and handling, resulting in detergent leakage.
[0004] Therefore, the inventor thinks of using the higher water-soluble non-woven fabric of mechanical strength to replace water-soluble film to make detergent packaging bag, but the weight fraction of water-soluble polyvinyl alcohol fiber in the traditional water-soluble non-woven fabric raw material is only 65- 80%, after dissolving in water, there will be a small amount of insoluble impurities, which are easy to adhere to the clothing, causing inconvenience to cleaning, or adhere to the washing machine, causing long-term accumulation to cause machine failure

Embodiment 1

[0043] Such as figure 2As shown, the detergent packaging bag of the present invention includes a bag-shaped main body 2 composed of two layers of the above-mentioned water-soluble non-woven fabrics superimposed, and a reinforcement sheet arranged on one side of the main body 2, and the reinforcement sheet is a strip-shaped reinforcement sheet 4 . The main body 2 has a rectangular shape as a whole, with a sealed compartment 6 in the middle, and a sealing portion on three edges, and the sealing portion is a strip-shaped sealing portion 8 . Specifically, the strip-shaped sealing portion 8 extends from one long side of the main body 2 to the other long side through a short side. A strip-shaped reinforcing sheet 4 adapted to the shape of the strip-shaped sealing portion 8 is hot-pressed on the outside of the strip-shaped sealing portion 8. The strip-shaped reinforcing sheet 4 is made of a non-woven auxiliary cloth, and the raw material fiber of the auxiliary cloth includes the abo...

Embodiment 2

[0046] Such as image 3 As shown, the only difference from Embodiment 2 is that the four corners of the inner edge of the strip-shaped sealing part 8 are rounded corners 12, and the rounded corners 12 can be obtained by controlling the shape of the strip-shaped sealing part 8 during hot pressing. Since the corners of the inner edge of the strip-shaped seal 8 are directly in contact with the detergent, they are easier to damage than the corners of the outer edge, and once damaged, the detergent will directly leak out, so rounded corners 12 are designed on the inner edge of the strip-shaped seal 8 More immediate protection against detergents in the compartment.

Embodiment 3

[0048] Such as Figure 4 As shown, the difference from Embodiment 1 is that not only the four corners of the outer edge of the strip-shaped sealing part 8 are rounded corners 12, but also the four corners of the inner edge are rounded corners 12, which can better protect the detergent, prevent leakage and cause loss, and stick Attached to the outside of the packaging bag affects sales.

Abstract

The invention relates to a water-soluble non-woven fabric. The water-soluble non-woven fabric is manufactured by processing polyvinyl alcohol vinylon fiber at least comprising vinyl alcohol-vinyl acetate copolymer through a hot rolling method, and is characterized in that the weight part content ratio of the polyvinyl alcohol vinylon fiber in the water-soluble non-woven fabric is 95 to 100 percent. When the water-soluble non-woven fabric is used for manufacturing a detergent packaging bag, on the one hand, less or even no undissolved impurity cannot exist in water, and cannot be adhered to clothes through washing water to avoid new contamination brought to the clothes to be washed, and on the other hand, the water-soluble non-woven fabric has necessary mechanical strength for ensuring safe transportation and storage. Moreover, a layer of auxiliary cloth containing a small amount of non-water-soluble fiber can be arranged on a sealed part of the detergent packaging bag to enhance the local strength of the sealed part, so that the sealed part is firm enough during hot pressing formation.

Description

technical field [0001] The invention relates to a non-woven fabric and a detergent packaging bag made of it. Background technique [0002] Water-soluble non-woven fabrics are usually made of polyvinyl alcohol fibers through bonding and hot-rolling methods, and can be dissolved in water at a certain temperature, so they are commonly used as interlinings for embroidery. [0003] As an indispensable daily necessities in modern life, detergents come in various forms including liquid, powder and granules. The traditional packaging bag is a large-dose package designed for long-term use. There is a problem that the dosage is not easy to control. Too little dosage will cause dirty washing, and too much dosage will damage hands and clothing. On some specific products, such as shampoo, there are also small-dose packaging bags, one-time use, quantitative and convenient. But also there is the shortcoming that is easily contaminated with detergent when opening the packaging bag, an...
