Nonwovens and machining method thereof

Abstract

The invention discloses a non-woven cloth and relative production, wherein the non-woven cloth is formed by non-hot-melt staple fiber whose mass content is not lower than 30% and hot-melt composite staple fiber, via thermal adhesive fixing method. And the invention utilizes the character that the surface of the hot-melt composite staple fiber has heated fusion function, and the invention uses thermal adhesive fixing method to fuse the face of hot-melt composite staple fiber to adhere the non-hot melt staple fiber to form non-woven cloth, therefore, the produced non-woven cloth has damp adsorption property, soft property, and flexibility, without sensibility on human body. And the invention utilizes the hot-wind non-woven device or thermal rolling non-woven device with low energy consumption and low cost.

Description

technical field [0001] The invention relates to the textile field, in particular to a nonwoven fabric and a processing method thereof. Background technique [0002] For non-hot-melt staple fiber, such as cotton fiber, viscose fiber, vinylon staple fiber, bamboo fiber, soybean fiber, etc., due to its good hygroscopicity, softness, no allergic reaction to the human body and natural biodegradation Nonwovens are very popular when they are used as disposable sanitary materials. However, since the surface of the non-thermofusible short fiber will not melt when heated, the fiber web cannot be reinforced by thermal bonding, but can only be reinforced by mechanical reinforcement. At present, the most widely used mechanical reinforcement method is the hydraulic acupuncture method, which uses water to spray the fiber web laid on the supporting screen, so that the fibers are entangled with each other under the action of jets in different directions (direct and reflection, refraction). ...

Problems solved by technology

However, since the surface of the non-thermofusible short fiber will not melt when heated, the fiber web cannot be reinforced by thermal bonding, and can only be reinforced by mechanical reinforcement.

At present, the most widely used mechanical reinforcement method is the hydraulic acupuncture method, which uses water to spray the fiber web laid on the supporting screen, so that the fibers are entangled with each other under the action of jets in different directions (direct and reflection, refraction). The fiber web is reinforced, but in the production of spunlace nonwovens, high-energy processes such as high-pressure water, water purification, and drying must be used, so its production cost is still lower than that of traditional thermally bonded reinforced nonwovens. Very expensive, and the equipment investment and maintenance costs of spunlace nonwovens are also very expensive

[0003] For thermally bonded nonwovens, because the fibers used are thermally meltable synthetic fibers, such as ES fibers, PP staple fibers, polyester staple fibers, etc., there are defects such as poor heat absorption, poor hand feeling, and poor skin-friendly properties.
