Abstract

The invention discloses a method for producing nonwoven fabric by thermal-calendering soft and smooth finishing. The method comprises the following steps: 1) mixing and opening fiber, and then transferring the opened fiber to a precision feeder; 2) forming a fiber layer in the precision feeder, transferring the fiber layer to a carding machine, finely carding the fiber layer into a single fiber status, forming a fiber net on a delivery net and then outputting the fiber net; 3) atomizing finishing liquor to the fiber net by a sprinkling device of an on-line finishing liquor applying device, and sucking below the fiber net by a suction device; 4) carrying out far infrared drying; and 5) carrying out thermal-calendering consolidation, coiling and splitting the finished product. The on-line finishing liquor applying device comprises the sprinkling device, a pressurizing device, a solution tank and the suction device which are sequentially connected together via a pipe, wherein, the sprinkling device is arranged above the delivery net in a finishing liquor applying area, and the suction device is arranged below the delivery net in the finishing liquor applying area. The nonwoven fabricproduced by the method provided by the invention has the advantages of low cost, high product efficiency and high profit under the same condition of 4-grade hand feel.

Description

Technical field [0001] The invention relates to a production method and device for a soft-finished hot-rolling nonwoven fabric. Background technique [0002] The production and processing of modern clothing cannot do without clothing interlining. The application of clothing interlining is a technological revolution in the clothing industry worldwide. Its application can not only replace sewing, simplify the process, and improve the grade, but also reflect the wisdom, inspiration and style of clothing design. It is the modern clothing Soul and essence. [0003] In the actual application process, the physical and chemical properties of the clothing lining and the fabric are required to be close, and the mutual affinity and compatibility are better, so that the spirit of the clothing can be more prominent. [0004] With the continuous improvement of people's clothing requirements and the development of textile technology, soft and slippery clothing fabrics that are post-finished by fi...
