Embodiment 1

[0022] A production process of cold pile method pure cotton spunlace nonwoven fabric, the production technique of the cold pile method pure cotton spunlace nonwoven fabric comprises the following steps:

[0023] S1: Cleaning and opening of raw cotton: Before opening the raw cotton, the foreign fiber detection machine is used to remove impurities from the raw cotton to ensure that the raw cotton is free of impurities. The raw cotton after rough opening is discharged through two pressure rollers, and then finely opened by the opener, and the fine fibers produced during rough opening and fine opening are absorbed into the dust bag on the outer wall by the vacuum cleaner;

[0024] S2: Carding into a web: Feed cotton into the cotton feeding box by weighing and feeding the cotton with a weighing curtain. The cotton feeding box is a two-way feeding airflow vibrating cotton box. The rotating speed of the roller is 120m / min, and the rotating speed of the stripping roller is 240m / min; ...

Abstract

The invention discloses a production technology of pure-cotton spunlace non-woven fabric by means of the cold-batch method in the technical field of non-woven fabric production. The production technology of the pure-cotton spunlace non-woven fabric by means of the cold-batch method comprises the following steps that S1, raw cotton is subjected to impurity cleaning and opening; S2, card web forming is conducted; S3, spunlace is conducted; S4, immersion and press-rolling are conducted; S5, primary batching is conducted; S6, stacking is conducted at normal temperature; S7, washing is conducted with water; S8, drying is conducted; S9, a finished product is obtained through batching. The process method that the pure-cotton spunlace non-woven fabric obtained after spunlace are directly subjected to cold-batch is adopted, on high temperature or high pressure is needed in the degreasing process, and the pure-cotton spunlace non-woven fabric is degreased at normal temperature; degreasing compositions and the pure-cotton non-woven fabric are combined in the immersion process, and the degreasing aim can be achieve through stacking at normal temperature under the action of the degreasing compositions. The inevitable requirement of a pre-degreasing technology for secondary drying and the inevitable requirement of a post-degreasing technology for high temperature and high pressure are met, energy saving is achieved, and the suitability and interactivity of the production environment are improved.

Description

technical field [0001] The invention relates to the technical field of non-woven fabric production, in particular to a production process of pure cotton spunlace non-woven fabric by cold pile method. Background technique [0002] Cotton spunlace non-woven fabric is also called pure cotton spunlace non-woven fabric. Cotton spunlace non-woven fabric is made of natural fiber pure cotton, through opening and loosening cotton, using cutting-edge carding machine, web laying machine and drafting machine After the pure cotton is sorted into a net, the cotton fiber is entangled into a cloth through a hydroentanglement machine by using the dense and numerous needle-shaped water columns formed after pressurization. It takes only 5 minutes from raw cotton to cloth, which saves spinning and weaving links compared with traditional weaving cloth, shortens working hours, saves a lot of energy consumption, labor and equipment, low-carbon environmental protection, energy saving and emission r...
