Description

A kind of preparation method of hollow warm-keeping material
Technical field
The present invention relates to heat insulating material preparation field, in particular to a kind of preparation method of hollow warm-keeping material.
Background technique
The preparation of heat insulating material, especially warming hollow yarns mainly utilizes composite spinning technology and solvent wet type gel Water-soluble fibre made of spin processes (generally based on vinylon fibre) is combined, i.e., structure is cotton fiber in outer layer, water-soluble Property fiber in internal layer, form double-layer structure.By the adjustment of spinning process, water-soluble fibre is effectively and uniformly coated on cotton The inside of fiber dissolves inner fiber using post-processing (moving back dimension), forms circular hollow yarn.Its resultant yarn feature be it is bulk, Lightweight, softness, but in sizing process, water-soluble vinylon fibre can be heated atrophy, the strength of yarn can drastically reduce from And influence weaving.So hollow yams fail to be developed and utilized well always, such product is limited in market into one Step exploitation.
Summary of the invention
To overcome above-mentioned technical problem, the present invention provides a kind of preparation method of new hollow warm-keeping material, this method Without using soluble vinylon fiber, will not lead to the problem of because moving back the strength of yarn caused by dimension can be drastically reduced.
Process flow of the invention are as follows: sliver through dissipating fibre dye, be dehydrated, drying, being packaged, grab cotton, mixing, shredding, at Volume, combing after formed the cotton carded sliver, hollow terylene through grabbing cotton, mix, open give, in rolls, combing after formed polyester fiber item, It is characterized in that, by the cotton carded sliver and polyester fiber item with quantity than forming ripe bar after 30: 70 draftings, drafting is mixed, again through rove, thin Outsourcing yarn is made in yarn, which is coated on stainless steel filament, semifinished material is made, then will be coated with spun yarn Stainless steel filament extraction in semifinished material, obtains hollow warm-keeping material.
Wherein, the diameter of the stainless steel filament is 0.1-1mm, and the surface of the stainless steel filament is coated with lubricating oils, The lubricating oils is and crude oil.
Using cotton fiber and the blended production outsourcing material of hollow terylene, it is coated on stainless steel filament surface, then will not Become rusty the extraction of steel long filament, form the hollow material structural body of cotton fiber and hollow terylene composition, inside hoarded it is a large amount of Still air can achieve relatively good warming effect.Also, due to not using soluble vinylon fiber, without moving back dimension Process will not have a negative impact to the strength of yarn.
Specific embodiment
The present invention is described further below with reference to embodiment: the process flow of the embodiment are as follows: sliver is by dissipating Fibre is dyed, is dehydrated, drying, being packaged, grabbing the formation cotton carded sliver after cotton, mixing, shredding, coiled, combing, and hollow terylene is by grabbing Cotton, mix, open give, in rolls, combing after formed polyester fiber item, which is characterized in that by the cotton carded sliver and polyester fiber item with quantity Than forming ripe bar after 30: 70 draftings, again through rove, spun yarn outsourcing yarn is made in mixed drafting, which is coated on stainless Semifinished material is made on steel long filament, then the stainless steel filament being coated in the semifinished material of spun yarn is extracted out, obtains hollow Heat insulating material.
Wherein, the diameter of the stainless steel filament is 0.1-1mm, and the surface of the stainless steel filament is coated with lubricating oils, The lubricating oils is and crude oil.
The carding process of cotton fiber and hollow terylene is the key procedure in production process, controls the weight of strip Irregularity and undercoat coefficient are crucial.In carding process, licker-in and the speed of doffer are suitably reduced, increase cylinder and licker-in Linear velocity ratio, the appropriate gauge reduced between cylinder and doffer, the appropriate speed for reducing cover board and cylinder can reduce fibre damage Increase with short flannel, reduces cotton net and float the bad phenomenons such as head and broken end, the relative velocity in workshop will be controlled 60 ~ 70%, quiet to reduce The adverse effect of electricity.
62 ~ 75%, temperature is controlled at 22.5 ~ 24 DEG C for the relative humidity control in workshop in mixed mixing in doubling step；Head simultaneously uses 6 Root simultaneously closes, and two Dao Yu tri- are using 8 and close, and speed is unsuitable excessively high, and speed uses 159 ~ 185m/min, the suitably relatively low control of speed System, can be effectively reduced broken end；It is mixed simultaneously using three, advantageously reduces weight unevenness.Roll surfaces will carry out antistatic agent material Processing, can effectively inhibit winding etc. bad phenomenons, head simultaneously using 6 feeding, shaping 16.8 ~ 17.0g/5m of weight, gauge 14.1 × 20 mm, bell mouth diameter 3.6mm；Two and using 8 feeding, shaping weight 15.8g/5m, 14 × 20 mm of gauge, loudspeaker Bore 3.4mm；Three and using 8 feeding, shaping weight 15.0g/5m, 13.5 × 19.5mm of gauge, bell mouth diameter 3.4mm.
Relative humidity control in workshop is 60 ~ 65% in Roving Frames, and to guarantee that production can be normally carried out, fiber is in rove Process is in sucting wet state, and 5.2 ~ 6.4 times of drafting multiple, 4.96 ~ 5.54g/10m of regular roving feeding, roller gauge rationally increases, Nip gauge suitably reduces, the appropriate pressure for increasing reel cage, is increased using low speed using the slightly larger antistatic rubber roll of hardness To the curable grip of fiber, it is ensured that drawing-off is gone on smoothly, flat with the solid carbon dioxide for improving rove, 23.5 × 33.0mm of gauge, twist factor 54 ~ 68,3.215 ~ 3.335 circles of axial winding density/cm, 550 ~ 690 r/min of ingot speed, 165 ~ 172 r/min of front roller speed, Operation element is done a good job of it, details caused by switch vehicle is avoided, appropriate adjustment tension guarantees that production is normally carried out；In spinning process According to the characteristic of fiber, appropriate back zone roller gauge bigger than normal, smaller back zone drafting multiple, again pressurization and appropriate low vehicle are taken Speed improves a solid carbon dioxide and puts down, reduce thickness section, reduce spinning end breaking and hairiness number, the twist to increase the cohesive force between fiber 930 ~ 1120 twists/m, 13900 ~ 17350r/min of ingot speed, at 22 ~ 25 DEG C, relative humidity is controlled 60 ~ 70% for temperature control；Carefully When yarn coats stainless steel filament, ramie yarn twist is 470~520 twirls, and orientation is that S is twisted, and semifinished material is obtained, finally by leading It draws equipment to pull out stainless steel filament, hollow warm-keeping material is made.
Using cotton fiber and the blended production outsourcing material of hollow terylene, it is coated on stainless steel filament surface, then will not Become rusty the extraction of steel long filament, form the hollow material structural body of cotton fiber and hollow terylene composition, inside hoarded it is a large amount of Still air can achieve relatively good warming effect.Also, due to not using soluble vinylon fiber, without moving back dimension Process will not have a negative impact to the strength of yarn.
