Abstract
The invention relates to a production process of high-gram-weight high-simulation multifunctional base cloth, which comprises the following process flows of: weighing and unpacking the raw materials in various proportions in corresponding weighing and unpacking machines respectively, feeding the raw materials into a long curtain, passing through a horizontal opener and a cotton mixing box, then feeding the raw materials into an independent vertical opener, a corresponding fine opener, a pneumatic cotton box and a carding machine respectively, wherein one path of the raw materials passes through a cross lapping machine and a drafting machine and then is converged and superposed with the other path of the raw materials in a conveying long curtain, and then the raw materials are wound into a finished product on a winding machine after being subjected to spunlace machine, drying machine and detection. The process solves the technical difficulties of unstable tearing, layering and winding effects and the like of high gram weight, so that the tearing strength, the breaking strength and the elongation of the product can be harmonious and uniform.
Description
One, technical field
The present invention relates to a kind of non-cloth production technology of spinning, relate in particular to a kind of production technology of high gram weight high imitation multi-functional base cloth.
Two, background technology
Since China's reform and opening-up, national economy improves day by day, and people's living standard has had significant raising, and it is material benefit again attractive in appearance that people develop into from simple availability the daily necessities demand.Particularly tangible consumption idea is being arranged aspect clothes, shoes and hats, the case and bag.And the eighties to the nineties this section in the period country such as America and Europe go out continuously crazy year sick, cause corium market to have a greatly reduced quality, and artificial leather market obviously is tending towards ascendant trend, this also is the big good opportunity that once develops.Along with the increase of market consumption, the product specification utmost point need improve at present.But all existing, existing artificial leather base fabric such as present most popular water acupuncture manipulation leather base cloth peel off defectives such as poor, that tearing strength is not high, the product isotropism is poor, feel emulation is relatively poor.This has become the key factor of restriction artificial leather healthy development of market.
Three, summary of the invention
The object of the present invention is to provide a kind of production technology of tearing height, intensity is good, flatness is good, simulated effect is good high gram weight high imitation multi-functional base cloth that has.
For achieving the above object, technical scheme of the present invention is: the described technological process of production is: at the bale opener 1 of weighing, the bale opener 2 of weighing, weigh and to be the raw material 1 of block short fiber in the bale opener 3 respectively, raw material 2, raw material 3 is opened into fiber bundle-like, and take by weighing the weight of fiber according to production requirement, then with raw material 1, raw material 2, the long curtain of raw material 3 feedings, these three kinds of raw materials are superimposed supply with horizontal opener and carry out shredding, littler fibre bundle after the shredding is supplied with blending box, in blending box, three kinds of raw materials are evenly mixed, supply with vertical opener 1 respectively in required ratio then, vertical opener 2, at vertical opener 1, shredding and supply with refined opener 1 respectively once more in the vertical opener 2, refined opener 2, at refined opener 1, in the refined opener 2 further shreddings so that raw material reaches tiny fibre bundle, send into air pressure hopper 1 then respectively, air pressure hopper 2, at air pressure hopper 1, get rid of the fibre bundle inner air in the air pressure hopper 2, the conpressed fibers layer, make the arranging density of fiber even, guarantee to feed carding machine 1, even and stable during carding machine 2, at carding machine 1, after carding machine 2 is carded to uniform fibre web with fibrage, the fibre web of carding machine 1 is delivered to cross lapping machine equably and carries out cross lapping, send into drawing machine then and carry out drawing-off, fibre web after drawing-off is finished is sent into and is carried long curtain, being delivered to the fibre web of carrying long curtain with carding machine 2 superposes and compresses, the fibre web of stack and compression is delivered to spun-laced machine, in spun-laced machine, carry out physical entanglement effectively, wet cloth after will reinforcing then is delivered to oven dry in the dryer stably, detect then, clot is shaped as finished product on coiling machine at last.
Described raw material 1 stings and accounts for the leather base cloth special polyester of proportioning 30% for the water of 2.2Dtex*51mm.
Described raw material 2 stings and accounts for the leather base cloth special polyester of proportioning 35% for the water of 1.67Dtex*38mm.
Described raw material 3 stings and accounts for the leather base cloth special polyester of proportioning 35% for the water of 2.22Dtex*51mm.
After the present invention adopts technique scheme, its advantage is: at the bottom of adopting this production technology successfully to solve high grammes per square metre tearability, layering, twine technological difficulties such as connecing effect shakiness, cloth cover out-of-flatness, cloth cover fluffing, thereby make MD, the CD of product can reach harmony to tearability and MD, CD to ultimate strength and percentage elongation.Product detects with dying material inspection center through Zhejiang Province's weaving, and the Main physical index all reaches and part surpasses FZ/T64012.2-2001 " People's Republic of China's textile industry method Non-Woven Fabric Industry check ".
Four, the specific embodiment
The present invention is a kind of production technology of high gram weight high imitation multi-functional base cloth, and its technological process is:
Each proportioning raw materials in the bale opener 1 of weighing, the bale opener 2 of weighing, the bale opener 3 of weighing is:
Water thorn, the leather base cloth special polyester of bale opener 1:2.22Dtex*51mm of weighing accounts for 30% of proportioning.
Water thorn, the leather base cloth special polyester of opening bag 2:1.67Dtex*38mm of weighing accounts for 35% of proportioning.
