1, high product strong/high force methods

a, increase large hot amount （ fiber fine, 缠绕 结点 more, fiber force uniform, strong/high force increase large, is increase large to 一定程 degree rear 反而会 decline ）;

c, increase product heavy （ in inner scope/range inner ）;

d, improve/increase 模头（模尖） and other temperature degree （同a）;

e, reduce output/production volume;

f, decrease small DCD（不 can small, 反而布脆 strong/high force decline, combined its it parameters 共同运 use ）;

g, increase large 网底吸风（ large heavy relatively obvious ）;

h, use MFI relatively low raw materials.

2, improve/increase product elongation methods

a, reduce hot amount or temperature degree （结点 slip 移路径变 large, 手感变 hard ）;

b, reduce 模头（模尖） 工 as temperature degree （同 upper ）;

c, decrease small output/production volume;

d, increase large DCD（ and a or b配 combined use more obvious ）;

e, reduce ring temperature degree （纺 filament ring temperature degree ）;

f, increase large 网底吸风（效果不太 obvious, large heavy relatively good ）;

g, fiber degree （改变 fiber structure, commonly used ）

h, improve/increase output/production volume （此 methods formed its it material indicators reduce, commonly used ）.

3, decrease small retardant force methods

a, reduce hot amount or temperature degree （ fiber coarse, rate large, retardant force small, efficiency 变差）;

b, increase large DCD（ increase fiber property, rate large, efficiency 变差）;

c, reduce filament ring temperature degree （ fiber cooling separation, structure 蓬松, rate increase large, combined hot gas can to reduce retardant force, improve/increase efficiency 目 ）;

d, decrease small 网底吸风（ fiber 由密变蓬松, rate large, large heavy relatively obvious ）;

e, reduce 模头（模尖） and other add hot 区 工 as temperature degree （ fiber coarse, rate large ）;

f, increase large amount 泵（ extrusion amount large fiber coarse, rate increase large, generally in fast speed mono use ）;

g, decrease small heavy （ in inner scope/range inner ）.

4, improve/increase efficiency methods

a, increase large hot amount or temperature degree （ increase fiber fine degree, decrease small rate, improve/increase can force, retardant force increase ）;

b, increase large electrical electrical pressure （ electrical 流）（极化 fiber, increase large fiber electrical can, improve/increase its can force ）;

c, in raw materials in add powder material or its it 驻极体（ improve/increase fiber electrical can force and electrical time, let fiber belt/tape more more electrical and belt/tape electrical time ）;

d, add large 网底吸风（ increase large fiber 密实程 degree, improve/increase fiber can force. large heavy obvious, commonly used ）;

e, reduce output/production volume （同 process lower, extrusion amount small, fiber fine, retardant force increase large ）;

f, improve/increase 模头（模尖） and other 区 工 as temperature degree （ melt flow property good, fiber fine ）;

g, improve/increase filament ring temperature degree （ fiber fine, generally is in room temperature rise high lower, retardant force increase relatively obvious, its it material indicators decline ）;

h, increase large powder material add amount.

5, can decrease small retardant force, also can improve/increase efficiency methods

a, increase large DCD meanwhile, increase hot amount or temperature degree, decrease small 网底吸风（ increase fiber fine degree and degree ）;

b, improve/increase fiber fine degree meanwhile reduce filament ring temperature degree （ ratio add cold plant/unit ）;

c, improve/increase fiber degree meanwhile, add large electrical electrical pressure （ electrical 流）, increase large powder 末 添 add amount;

d, improve/increase fiber fine degree, decrease small heavy （不 commonly used ）.

6, can improve/increase strong/high force, also can improve/increase elongation methods

a, reduce hot amount or temperature degree, decrease small DCD, increase large 网底吸风（ used for ring temperature degree high, raw materials MFI high formed material indicators combined 格）;

b, increase large hot amount or temperature degree, increase large DCD, decrease small 网底吸风（ used for ring temperature degree low, raw materials MFI low formed material indicators combined 格）;

c, decrease small output/production volume;

d, increase fiber fine degree meanwhile reduce filament ring temperature degree.

7, decrease small product CV value methods

a, for 应改变模头各区 工 as temperature degree （克 heavy small rise temperature, drop temperature ）;

b, local efficiency, retardant force and CV value 矛盾时 can using/adopting in its add upper sheet/plate （ improve/increase local filament ring temperature degree ）;

d, toward heavy CV value main/primary and formed system speed degree stability property has 关.

8, 出现“Shot” causes

a, as temperature degree setting 不当（ high or low, generally high easy 出现）;

b, raw materials or masterbatch 太脏（ generally overall, or large 面积出现）;

c, use rear 期, 模尖脏（ has is local filament defect or large 面积出现, can using/adopting 刮刀刮模尖 solution ）;

d, 模尖周围 has carbon material or 脏堵造 formed filament defect （ usually is 异常停 machine formed. generally is local a small amount of 出现, can using/adopting 刮刀刮模尖 solution ）;

e, local or has material loss 伤（ effect/influence positive filament gas uniform property, local 出现并伴 has toward thin 沟出现）;

f, output/production volume high or low （ generally is large 面积出现, reduce or improve/increase output/production volume solution ）;

g, raw materials MFI high or low （ usually high easy 出现）;

h, raw materials in has water.

9, 出现“飞花” causes

a, hot amount large or temperature degree high （断 fiber more ）;

b, 各区工 as temperature degree high （断 fiber more ）;

c, DCD太 small （布太密实, effect/influence efficiency ）;

d, filament ring temperature degree high （同a）;

e, in add recycling material 时, recycling amount large recycling material MFI 不定;

f, output/production volume low;

g, 网底吸风 parameters setting or 网帘太脏（吸风 small, fiber can by separation in upper, 脱离网帘）;

h, raw materials MFI high.
