Embodiment 1

[0038] The manufacturing process of a kind of highly elastic PP cotton provided by the present invention uses two kinds of raw materials of polyester and nylon. When processing, the use ratio of these two kinds of raw materials is 1:1, and its processing steps are as follows:

[0039] In the first step, the polyester raw material and the nylon raw material are respectively put into the screw extruder for heating and melting, so that both materials are in a state that can be molded.

[0040] In the second step, the melted polyester raw materials and nylon raw materials are respectively fed into the spinning box for filtration to filter out the impurities inside each.

[0041] The third step is to put the polyester raw material and nylon raw material filtered by the spinning box into the metering pump for quantitative feeding, so that the ratio of the two is strictly controlled to keep the amount of the two at 1:1, and at the same time control each The content of polyester and n...

Abstract

The invention discloses a manufacturing process of high-elasticity PP cotton and the manufactured PP cotton. The manufacturing process comprises the following processing steps: respectively heating and melting a polyester raw material and a chinlon raw material; respectively filtering the molten polyester raw material and chinlon raw material; respectively feeding the filtered polyester raw material and chinlon raw material into a metering pump for quantitative material taking; feeding the polyester raw material and the chinlon raw material which are quantitatively taken into a spinneret plate respectively to be converged at a yarn outlet panel of the spinneret plate; adhering each group of converged polyester raw material and chinlon raw material through heat setting and hot pressing to form integral fiber; perforating the formed integral fiber through a perforating wire to form a through hole; enabling the integral fiber with the through holes to pass through shaping filaments capable of extending out of convex points to form concave parts; and enabling the integral fiber forming the concave parts to pass through a molding sleeve capable of extending out of convex strips to form an air duct. The manufactured PP cotton has the following beneficial effects that the compression elastic recovery rate is high, the product stress intensity is high, and the elastic recovery rate and the bulkiness are not changed after multiple times of compression and water washing.

Description

technical field [0001] The invention relates to the technical field of manufacturing PP cotton used in bedding, in particular to a manufacturing process of high-elastic PP cotton and the manufactured PP cotton. Background technique [0002] The structural strength of the existing PP cotton is average, and after a long time of use, it will collapse and deform. At the same time, when using traditional PP cotton, the comfort is not high, and it cannot bring users a better experience. Contents of the invention [0003] 1. The technical problem to be solved by the invention [0004] In view of the above-mentioned existing PP cotton, the structural strength is average, and after a long time of use, it will collapse and deform, and the traditional PP cotton does not have a high sense of comfort when used, and cannot bring a better experience to users. To solve the problem, this application provides a manufacturing process of high elastic PP cotton and the manufactured PP cotton...
