Abstract
The invention relates to a method for producing composite needle punched cotton through pneumatic lapping. Blend staple fiber with the length smaller than 100 mm and larger than 5 mm is selected, the staple fiber polyester, waste cotton and other raw materials are mixed in any proportion, and the mixture is processed sequentially through a cotton feeder, an opener and a pneumatic lapper and then processed sequentially through pre-needling, down needling, up needling, reeling, packaging and storage. Through the technical scheme, the staple fiber is carded for lapping through the pneumatic lapper, so that the produced composite needle punched cotton is light and thin but high in density, good in breathability, not prone to deformation and the like; the needle punched cotton can be packaged in an evacuated mode so that stock area can be reduced, and transportation and storage can be facilitated; waste cotton in the production process is fully utilized, environmental pollution is reduced, and resources can be effectively allocated.
Description
Technical field
The present invention relates to acupuncture cotton technical field, particularly relate to a kind of air pressure and become the manufacture method of net composite acupuncture cotton.
Background technology
The fabrication processing of traditional acupuncture cotton is to feed cotton machine → pre-comb → opener → carding machine → lapping machine → pre-thorn → lower thorn → upper thorn → clot → packaging → warehouse-in.It is to make to interconnect winding between fiber by combing that traditional handicraft is produced the combing of acupuncture cotton, and fibre length is had to certain requirement, so just can make to interconnect between fiber winding, carding.And for the imitative silk flosssilk wadding of a large amount of production, gum sprayed cotton, without the company of collodion, acupuncture cotton, a lot " waste cotton " can drop on machine, the leftover pieces that also have cutting to get off, because these " waste cotton " fibre lengths are shorter, cannot again be used traditional carding machine carding, so can not recycle, enterprise will spend certain energy to process these " waste cottons " it is transported to soot or burns, and can cause like this waste of environmental pollution and resource.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, our company adopts random web-laying equipment to become net to fiber.The present invention by the following technical solutions, a kind of air pressure becomes the preparation method of net composite acupuncture cotton, the raw material arbitrary proportions such as staple fibre terylene and waste cotton are mixed, through feeding cotton machine → opener → air pressure lapper → pre-thorn → lower thorn → upper thorn → clot → packaging → warehouse-in, key step is as follows successively:
(1) select materials: choose the fiber that mixes short fiber material fibre length <100mm and >5mm, the raw material arbitrary proportions such as staple fibre terylene and waste cotton are mixed;
(2) shredding: mixed batching is sent into opener and carry out shredding, in shredding process, fiber is fully mixed, and sends in hopper and stores after shredding;
(3) air pressure becomes net: raw material is pressed to lapper by the junction inhaling air of the gentle pressure lapper of opener, air-flow blows from the top down, fiber is produced to pressure, again by the discaling roll of 0.35 meter of two diameter by fiber extrusion out, make bat basic forming, and the thickness of bat can regulate by the distance of controlling between fiber speed and two discaling rolls that be inhaled into;
(4) acupuncture: to becoming the fiber after net to carry out acupuncture, adopt lower thorn-upper thorn-lower thorn-upper thorn to carry out, form certain thickness acupuncture cotton; Pressure grenadine and web by acupuncture are combined with each other smoothly, web and grenadine can not only be combined firmly by intensive acupuncture, and intensive pin hole has also ensured the gas permeability of composite acupuncture cotton;
(5) formed package: reference product require to baking oven cotton out cut, cutting edge, carry out simultaneously reel and packaging.
Compared with prior art, our company adopts air pressure lapper to carry out carding to staple fibre, the composite acupuncture cotton that makes to produce had both had frivolous but density is high, good permeability, the feature such as not yielding, thereby can reduce stock's area by the packaging of finding time again, is convenient to transport and stores; And fully " waste cotton " in production process used, reduce environmental pollution, resource can effectively be configured.
Detailed description of the invention
This air pressure becomes the preparation of net composite acupuncture cotton, and the raw material arbitrary proportions such as staple fibre terylene and waste cotton are mixed, and through feeding cotton machine → opener → air pressure lapper → pre-thorn → lower thorn → upper thorn → clot → packaging → warehouse-in, key step is as follows successively:
(1) select materials: choose the fiber that mixes short fiber material fibre length <100mm and >5mm, the raw material arbitrary proportions such as staple fibre terylene and waste cotton are mixed;
(2) shredding: mixed batching is sent into opener and carry out shredding, in shredding process, fiber is fully mixed, and sends in hopper and stores after shredding;
(3) air pressure becomes net: undertaken by suction (0.8-2.5kg), fiber being pressed to lapper by the junction inhaling air of the gentle pressure lapper of opener after shredding by opener.Ensure that fiber evenly enters air pressure lapper.Air pressure lapper is a cuboid, high 1.2 meters, wide 2.8 meters, long 0.4 meter, air-flow blows from the top down, and fiber is produced to pressure, again by the discaling roll of 0.35 meter of two diameter by fiber extrusion (up-down rollers pressure 0.2-0.8kg) out, make bat basic forming, do not need, through lapping and combing, to save time and the energy.And the thickness of bat can regulate by the distance of controlling between fiber speed and two discaling rolls that be inhaled into;
(4) should frame one reel wire yarn below lapping machine, when the web of completing transports while entering the acupuncture stage from lathe above, grenadine should be entered to pressure roller from below traction together and overlap with web, and pressure by the pressure roller tractive force during with rolling just can web and grenadine overlap and bring the acupuncture stage into;
(5) acupuncture: to becoming the fiber after net to carry out acupuncture, adopt lower thorn-upper thorn-lower thorn-upper thorn to carry out, form certain thickness acupuncture cotton; Pressure grenadine and web by acupuncture are combined with each other smoothly, web and grenadine can not only be combined firmly by intensive acupuncture, and intensive pin hole has also ensured the gas permeability of composite acupuncture cotton;
(6) formed package: reference product require to baking oven cotton out cut, cutting edge, carry out simultaneously reel and packaging.
