[0002] For the convenience of carrying, gift boxes and small and medium-sized packaging boxes usually have a handbag on the box. Most of the current handbags are made of single-layer plastic injection molding. Although the plastic handbag has high strength, it feels stiff and poor in comfort. A handbag made of PE and PET glued together. This kind of handbag has good hand feeling and strong toughness. However, due to the use of glue, it is easy to delaminate in high temperature weather or when it is heated, making the appearance fuzzy, unsightly and reducing Strength, most of the common handbags on the market are made of non-woven fabrics. Non-woven handbags are made of non-woven fabrics. Easy to decompose, no

Example Embodiment

[0050] The second embodiment: The difference from the first embodiment is that PET / PET is selected in step S1, and the temperature of the hot rolling mill in step S5 is 110°C, which can produce a hard-handed, thin, and high-strength fabric. Acoustic stitching, and since the melting point of PET is 110°C, the temperature of the hot rolling mill is controlled at 110°C to ensure that PET / PER can melt and bond during hot rolling.

Example Embodiment

[0051] The third embodiment: the difference from the first embodiment is: PET / PP is selected in step S1, wherein the weight of PET is 70%-90%, the weight of PP is 10%-30%, and the temperature of the hot rolling mill is 150℃, select PET / PP composite materials for mixed spreading, and the weight of PP accounts for 10%-30%. The fabric produced is made of PET on one side and PP on the other side. When making a packaging bag, the material is When one side of PP touches, it can be heat-sealed by the sealing machine, and the packaging bag after heat-sealing has a firm structure and is not easy to be damaged. The melting point of PP is 150°C. Therefore, when the fabric enters the 150°C hot rolling mill, PP melts and other The fibers are bonded into sheets.

Example Embodiment

[0052] The fourth embodiment: the difference from the first embodiment is that PET / PERPE is selected in step S1, wherein the weight ratio of PET is 70%-90%, and the weight ratio of PETPE is 10%-30%. The temperature is 130°C, PETPE has a skin-core structure, the outer layer is PE with a lower melting point, and the inner layer is PET with a higher melting point, so that the melted PE can be used as an adhesive to bond the fibers together; the melting point of PE When the cotton web enters the hot rolling mill at 130°C, PE melts and acts as a binder to bond the fibers into a sheet-like cloth without adding other binders, thus realizing the lightweight of the cloth and making the cloth Lighter and thinner.

Abstract

The invention discloses a light and high-strength non-woven fabric production process and aims to solve the problem that traditional non-woven fabric is thick and not enough in strength. According tothe technical scheme, the process mainly includes the following steps of opening, cotton blending, carding, cross lapping, drawing, shaping, cloth storage, rolling and slitting; cross lapping includesthe step that a cotton web is sent from a first carding machine to a lapping machine, the discharge direction of the lapping machine is perpendicular to the feeding direction of the lapping machine,and the web sent from a cross lapping machine is a web having cross texture. According to the light and high-strength non-woven fabric production process, the produced non-woven fabric has the advantages of being light and uniform in strength, meanwhile reinforcement is conducted in the longitudinal direction, and the process is widely applied to packaging and other fields.

Description

technical field [0001] The invention relates to the field of non-woven fabrics, more specifically, it relates to a light, thin and high-strength non-woven fabric production process. Background technique [0002] For the convenience of carrying, gift boxes and small and medium-sized packaging boxes usually have a handbag on the box. Most of the current handbags are made of single-layer plastic injection molding. Although the plastic handbag has high strength, it feels stiff and poor in comfort. A handbag made of PE and PET glued together. This kind of handbag has good hand feeling and strong toughness. However, due to the use of glue, it is easy to delaminate in high temperature weather or when it is heated, making the appearance fuzzy, unsightly and reducing Strength, most of the common handbags on the market are made of non-woven fabrics. Non-woven handbags are made of non-woven fabrics. It is easy to decompose, non-toxic and non-irritating, rich in color, low in price, an...
