Background technology
The filtering material being generally used for filter bag is formed by holding knoisphere, filter course and supporting layer, wherein hold knoisphere to play a part to collect dust, filter course plays filter dust, and supporting layer holds knoisphere and filter course in order to support, and ensures that filter bag has enough intensity in use simultaneously.Hold one deck that knoisphere is most critical in filter bag, play a decisive role to the life-span of filter bag, dust containing capacity is higher, illustrate that it can hold the ability of fine dust stronger, the ability slowing down the rising of filter course resistance is also stronger, and the life-span of filter bag is just long, otherwise the life-span of filter bag is shorter.In prior art, hold knoisphere and be limited to material and manufacture craft, dust containing capacity is difficult to improve.
Summary of the invention
The present invention mainly solves the technical problem existing for prior art, provides a kind of height for filter bag and holds dirt filtering material.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of height for filter bag holds dirt filtering material, there are the three layers of iterative structure holding knoisphere in the middle of upper overcoat and the clamping of lower overcoat, three layers adopt acupuncture or ultrasonic welding process to be combined into one, and total grammes per square metre that described height holds dirt filtering material is 50-200g/m
2, wherein overcoat adopts grammes per square metre to be 10-30g/m up and down
2polypropylene spun-bonded non-woven fabrics make, object gives high holding the certain intensity of dirt filtering material, clamps appearance knoisphere simultaneously, plays anchoring fiber and prevent the effect of fibre shedding; Holding knoisphere is the high key stratum holding dirt filtering material, and grammes per square metre is 30-140g/m
2, adopt polypropene staple raw material, height is fluffy, the 3-D solid structure of high voidage to utilize mechanical carding and mechanical net-forming technology to be made into.
As preferably, described appearance knoisphere adopts the curling polypropene staple of 30-70% weight content and the plain polypropylene short fiber mixing of 30-70% weight content, wherein the fiber string diameter of curling polypropene staple is 1.5D-15D, and the string diameter of plain polypropylene short fiber is 1.5D-15D; Utilize the curl characteristics of curling polypropene staple, ensure that filter material is fluffy, have higher voidage, plain polypropylene short fiber is used for filling space, makes it have more fiber to hold dust.Also single curling polypropene staple or plain polypropylene short fiber can be selected to make and to hold knoisphere.
Height for filter bag holds a dirt filtering material, and preparation method is: curling polypropene staple and plain polypropylene short fiber mix by certain weight ratio by a., then by fiber opening, then by mechanical carding, fiber is carded to uniform fibrage; B. become net by machinery, Thin fiber layers is layered on from level to level on lower overcoat, then cover upper overcoat, then by acupuncture or ultrasonic welding process, trilaminate material is combined into one; C. required door width is finally cut into, and rolling.Wherein adopt acupuncture or ultrasonic bonding combination process, three layers are simply reinforced by object, be unlikely to layering, so that processing and manufacturing, so combination process is worthy of careful study very much: if take acupuncture combination process, needling density can not be too high, in order to avoid affect fluffy degree and the porosity of material, needling density is uniform 10-100 pin/cm
2; If adopt ultrasonic bonding combination process, pad area is the 0.5%-5% of equal cloth filter area, guarantees that material has high-loft and high porosity.
Adopt technique scheme, make the present invention have following characteristics: 1, high dust containing capacity, hold knoisphere and select polypropylene short fiber to be raw material, adopt mechanical carding and mechanical net-forming technology, form the 3-D solid structure of high fluffy and voidage, have larger volume, higher pulp freeness, fluffy degree is high, porosity is large, can hold more dust, every square metre of dust containing capacity can reach 800-1200g, and only has 200-600g with other material every square metre dust containing capacity of grammes per square metre; 2, highly-breathable, production technology adopts mechanical carding and mechanical net-forming technology, and fiber distributes in a jumble and piles up in a jumble, thus forms high fluffy and high porosity 3-D solid structure, gives this material highly-breathable; 3, high working property energy, upper and lower surface respectively has one deck overcoat, and giving this material has good mechanical performance, is convenient to add unreel man-hour and draw, and this material material used is polypropylene simultaneously, meets filter bag machine-shaping and adopts ultrasonic welding process.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention.
Detailed description of the invention
