[0002] Non-woven fabrics, also known as non-woven fabrics, are composed of directional or random fibers. They are a new generation of environmentally friendly materials. Low cost, recyclable, etc. For example, polypropylene pp pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. Because of the appearance of cloth and certain It is called non-woven fabric because of its performance. Traditional non-woven fabrics are generally made of polypropylene fibers, so the softness of traditional non-woven fabrics is not very good. Traditional non-woven fabrics generally do not have silk fiber layers, so the texture effect is not good. very good

Embodiment Construction
[0018] refer to figure 1 , a method for preparing a soft hot-rolled non-woven fabric of the present invention, comprising a silk fiber non-woven fabric layer 1 and a composite fiber non-woven fabric layer 2, and the composite fiber non-woven fabric layer 2 is sandwiched by hot-rolled bonding In the middle of two layers of silk fiber non-woven fabric layer 1, said silk fiber non-woven fabric layer 1 is formed by mixing silk fiber 11 and a small amount of ES adhesive fiber 12, and said composite fiber non-woven fabric layer 2 is made of Polypropylene fiber 21, polyester three-dimensional crimped hollow fiber 22 and a small amount of ES adhesive fiber 12 are mixed, and the production process of the soft hot-rolled non-woven fabric includes the following steps:
[0019] a. Making the silk fiber non-woven fabric layer: mix silk fiber 11 and ES bonding fiber 12 according to the ratio of 80 to 90 parts of silk fiber and 10 to 20 parts of ES bonding fiber, and then go through cotton b...

The invention discloses a soft hot-rolled non-woven fabric and a preparation method thereof. The soft hot-rolled non-woven fabric comprises silk fiber non-woven fabric layers and a composite fiber non-woven fabric layer, wherein the composite fiber non-woven fabric layer is clamped between two silk fiber non-woven fabric layers in a hot-rolled bonding manner; the silk fiber non-woven fabric layers are formed by blending silk fibers with a small amount of ES bonding fibers; the composite fiber non-woven fabric layer is formed by blending polypropylene fibers, polyester three-dimensional crimp hollow fibers and the small amount of ES bonding fibers. According to the soft hot-rolled non-woven fabric disclosed by the invention, the polypropylene fibers of a traditional non-woven fabric are replaced with composite fibers consisting of the polypropylene fibers and the polyester three-dimensional crimp hollow fibers, so that the softness of the traditional non-woven fabric is improved; in addition, the silk fiber layers are additionally arranged on the surface of the traditional non-woven fabric, so that the texture effect of the traditional non-woven fabric is improved.
