Problems solved by technology

[0003] The back panel of the backpack in the prior art generally uses EVA material and pearl cotton material as the internal filler, which lacks air permeability, resulting in the accumulated sweat not being able to evaporate in time, and the long-term accumulation of sweat produces peculiar smell and leads to the growth of bacteria, which in turn leads to skin problems ; so a new solution is needed to solve this problem

Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] A production process for the back panel of a backpack, comprising the following steps: step S1, carding DuPont sorona fibers into a thin net state through a roller carding machine, and sending them to a web laminating machine for standby, mixing oyster fibers with a roller carding machine and hot-melting short The fiber is carded into a thin net state, sent to the web-laying machine and laid on the top of the sorona fiber, and the fiber web with a grammage of 10-40 grams per square meter is obtained from the web-laying, and the fiber web is finally wound up; DuPont sorona fiber is used as the basic material Lay the net to prepare the fiber web, so as to make use of its excellent stretchability and recovery ability to ensure the elasticity of the fiber web, and then meet the elastic requirements of the backpack back panel 4, add hot-melt short fibers, so...

Abstract

The invention discloses a production process of a back piece of a backpack, relates to a backpack and aims to solve the problem of lack of breathability. The technical scheme of the production processof the back piece of the backpack is characterized by comprising steps as follows: S1, Dupont sorona fiber is carded in a thin net state through a roller carder and sent into a net paving machine onstandby, oyster fiber mixed hot-melt short fiber is carded in a thin net state by a roller carder, sent into the net paving machine and paved above sorona fiber, and a fiber net with 10-40 g / m<2> is prepared from the paved net and finally coiled to form a fiber net; S4, an inner-core blank is sent into a hot cutting press and is cut into a required appearance by a hot cutting die of the hot cutting press, and a filling inner core is prepared; and S5, the filling inner core is wrapped with fabric, and the back piece of the backpack can be made. By means of the production process of the back piece of the backpack, the breathability of the back piece of the backpack is effectively improved, so that the sweating capability is improved, and the hidden danger of breeding of bacteria is further reduced.

Description

technical field [0001] The invention relates to a backpack, more specifically, it relates to a production process of the back panel of the backpack. Background technique [0002] Backpacks are a general term for backpacks that are carried on the shoulders. According to the different uses of the backpacks, they are divided into computer backpacks, sports backpacks, fashion backpacks, school backpacks, back strap bags, military backpacks, mountaineering bags, etc.; The back panel of the backpack is the part of the backpack that fits the back of the user, and it cooperates with the straps to bear the weight of the entire backpack. [0003] The back panel of the backpack in the prior art generally uses EVA material and pearl cotton material as the internal filler, which lacks air permeability, resulting in the accumulated sweat not being able to evaporate in time, and the long-term accumulation of sweat produces peculiar smell and leads to the growth of bacteria, which in turn l...
