Embodiment 1

[0018] refer to figure 1 It is the embodiment one of a kind of hot-rolled thin nonwoven production process of the present invention, comprises the following steps successively:

[0019] A. Cotton feeding and cotton blending: put 75% polyester fiber, 5% nylon fiber, 7% viscose fiber and 13% ES fiber into the conveyor belt of the cotton feeding machine;

[0020] B. Cotton opening: the fiber raw material is transported from the cotton feeder to the cotton opener, and the fiber raw material is broken up;

[0021] C. Carding: Straighten out the fiber raw materials scattered in step B;

[0022] D. laying the net: superimposing the fiber raw materials straightened out in step C vertically and horizontally into multiple layers;

[0023] E. hot rolling: the fiber raw material stacked into multiple layers in step D is sent to a hot rolling mill, and the multi-layer fiber raw material is hot rolled into a nonwoven fabric by the hot rolling mill roll;

[0024] F. Cooling, inspection, c...

Abstract

The invention discloses a process for producing hot rolling thin nonwoven fabric, sequentially comprising the following steps of: feeding cotton, mixing cotton, adding ES fiber (ethylene-propylene side by side) in fiber raw material, opening, carding, lapping, hot rolling, cooling, testing, reeling into products, weighing and warehousing. The process disclosed by the invention has the advantages that: ES fibers are added, thus washing fastness of the supported hot rolling thin nonwoven fabric is greatly improved compared with a common nonwoven fabric, and the supported hot rolling thin nonwoven fabric is resistant to pilling; the cloth cover of a base fabric is smoother and the fastness is greatly improved, the washing fastness, washing shrinkage and heating shrinkage are all obviously improved, and the quality is above the national textile industry standard FZ / T6004-93.

Description

technical field [0001] The invention relates to a production process of hot-rolled thin nonwoven fabric. Background technique [0002] my country is a big garment producing country, with an annual garment output of about 45 billion pieces and a required interlining of about 4.5 billion meters. Its national interlining export has exceeded 600 million meters. According to expert estimates, the amount of clothing consumption in 2020 will be about 300% of that in 2010, that is, the average annual growth rate will be 8%. Therefore, the consumption amount of interlining will also "rise with the tide" of clothing, which can increase by 8% every year. [0003] The current hot-rolled thin nonwoven fabric is easy to destroy the good characteristics of the original base fabric in the production process, and is prone to problems such as pilling and washability. Contents of the invention [0004] The purpose of the present invention is to provide a production process of hot-rolled t...
