Embodiment Construction

[0012] The key to the design concept of the present invention is that the method for manufacturing shaped cotton with specific shape microgroups is composed of raw material preparation (1), raw material mixing (2), uniformity (3), preparation of microgroups (4), heating and shaping of microgroups (5), micro-aggregate shaped product (6), weighing (7), specific shape pre-pressing (8), specific shape heating and shaping (9), specific shape shaping product (10), process composition.

[0013] The key to the design idea of ​​the present invention is: the raw material preparation (1) adopts two kinds of fibers with different high and low melting points to feed according to the ratio set by the final finished product, and the high melting point fiber is the skeleton of the shaped cotton product The ratio of raw materials is 50%-95%, and the low-melting fiber is a hot-melt setting adhesive, and the ratio is 5%-50%.

[0014] The key point of the design concept of the present invention i...

Abstract

A method for preparing microbial insulating padding of special shaped type includes using fiber material containing high melting point fiber and low melting point fiber to prepare micro-hairball then obtaining micro ball insulating padding of special shaped type after process of gathering, compressing and heat-setting.

Description

technical field [0001] The invention relates to the technical field of non-woven shaped cotton. Background technique [0002] The invention relates to a method for manufacturing specific-shaped microgroup shaped cotton. The existing technologies for non-woven shaped cotton all use carding to form a web, and make products of equal width and thickness after shaping according to the thickness required by the shaped cotton or the thickness of the technical limit. If a product with a specific shape is required, it needs to undergo secondary processing such as cutting to obtain the final product with a specific shape. [0003] The existing technical process is long and complicated, the rate of raw materials is low, the cost is high, and it is impossible to produce products with special shapes at one time, and it is difficult for the final finished product to meet the use requirements of basically the same deformation resistance in different directions.
