Description

Comprise a kind of blending type aramid fibre containing sulfuryl fibre blend and by its yarn, fabric and preparation method

Technical field

The fibre blend comprising a kind of blending type aramid fibre containing sulfuryl and the yarn, bondedfibre fabric and the goods thereof that are obtained by it, and their preparation method.

Background technology

Current textile fabric gets more and more, and function is also varied, and people are obtained by the combination of different product and upgrade better properties of product, and security performance is our another pursuit outside the performance such as attractive in appearance, warming, fashion, function.Although flat textile product can realize many functions, often very easily burn when running into high heat, flame, the flame spread can be burnt, skin ambustion, and the chemical fibre high temperature drop of melting drippage also can cause huge injury to human body skin.Flame retardant textiles becomes people to be pursued one of textiles safety and selects greatly.

Flame retardant textiles can select Final finishing converted products also can select inherent flame retardant product.Final finishing converted products is by impregnating method, the chemical reagent with anti-flaming function is coated in the surface of fabric, makes textiles obtain fire-retardant performance; Inherent flame retardant is by the improvement to material, is joined in chemical fibre by the material with anti-flaming function, or design and synthesis has the new chemical fibre of inherent flame retardant characteristic.

But, through the fire resistance fibre that flame-retardant after-finishing obtains, there is Flame Retardancy can be unstable, flame-retardancy requirements is low, durability, water-wash resistance are poor, and can constantly decline in fire resistance after washing, properties of product cannot keep, produce the possibility of a large amount of particular matter during burning, in use still there is very large potential safety hazard.Simultaneously, conventional chemical fibre easily produces melting drip phenomenon when burning, even if add fire retardant matter be also difficult to burn when avoiding flame contact and produce melt drip, the drips of melting is at human body surface, cause the damage of human body skin, muscle, multiple soft tissue irrecoverability, even threat to life.Limit the application of product, too increase the processing of product, replacement cost.

There is inherent flame retardant performance, do not produce and melt the optimal selection that the chemical fibre dripped is processing flame retardant textiles.But because mostly above-mentioned inherent fire-retardant fiber is, for the product of commercial Application, special dimension exploitation, the wearability of fiber to have some problems, as product is comparatively hard, comfort is poor, it is low to get damp again, dyeability is poor.

Therefore, durable flame-proof performance has excellent handle softness concurrently simultaneously, cunning is glutinous, warmth retention property good, regain is high to the object of the present invention is to provide one to have, and has excellent ABRASION RESISTANCE, more comfortable feel simultaneously, lower smoke toxicity, the yarn in service life more of a specified duration, fabric and goods thereof.

Summary of the invention

The present invention adopts a kind of blending type aramid fibre (A) containing sulfuryl of the inherent fire-retardant fiber with durable flame-proof performance to carry out hybrid process with animal protein fiber (B), because a kind of blending type aramid fibre (A) containing sulfuryl has soft, sliding glutinous, warmth retention property is good, regain is high, the features such as dyeability is good, with the blending of natural animal protein fibre after, product is while the long-term inherent flame retardant performance of acquisition, wiriness can not be produced, the problems such as degree of comfort decreased, fabric still has comfortableness specific to animal protein fiber, reflecting feel and sliding glutinous feel, can be applicable in various high-grade fabric, be particularly suited for uniform, Western-style clothes, overcoat, the high-grade garment industry such as Men's Shirt, and sweater trousers, the wool spinnings such as woolen stockings are woven, knit product, also can be used as aircraft, high ferro, public transport, the seat be equipped with in the vehicles such as steamer, curtain, wall cloth, the textiless such as bed clothes.

Preferably, the method forming described bondedfibre fabric is water acupuncture manipulation, needle point method or glue spraying method.

The present invention " water acupuncture manipulation " used is known, is mainly used in reinforcing, being particularly useful for pre-reinforcement nonwoven fabric.For to reinforce or the hydraulic pressure of pre-reinforcement is usually about 150 bar or is less than 50 bar.Facts have proved, for generation of the hydraulic pressure of the pore structure of the nonwoven fabric of fiber web of the present invention or loose combination within the scope of 60 ~ 120 bar.The technique of water acupuncture manipulation of the present invention is exemplified below, but is not limited to following technological process: fibrous raw material → bale opener → mixed long curtain → first shredding → blending box → smart shredding → air pressure cotton box → carding machine becomes net → cross lapping → water thorn → oven dry → trimming package.When adopting water jet process, the fineness of optimum fiber is 1.5D.

The present invention " needle point method " used refers to that comprising fiber interweaving instruments such as making such as pin thrusts and extract the bedding and padding autofrettage of the step of bedding and padding.The present invention does not limit the quantity of acupuncture.But, the same with other acupuncture manipulation, optimization must be carried out to provide the binding capacity between required pore structure and each layer fabric to many factors.These factors comprise the size of pin and type, acupuncture amount, depth of needling, according to fiber type, length, Denier unit and web density to coarse-fibred suitable selection.Consider the performances such as the intensity of filtering material of thermal stability, apparent density, throughput, during acupuncture, needling density is more satisfactory at 800 pin/more than cm2.Needling density is too low, and the complexing of fiber and fiber is poor, the trend that the intensity of producing the filtering material of thermal stability obtained reduces, apparent density also has reduction simultaneously.End product filtering material, pinprick is thick, Air permenbility is too high, to the arresting efficiency of dust in the trend reduced, such filtering material is undesirable.On the contrary, needling density is too high, can be caused because acupuncture causes the damage of fiber or reinforced textile fabric (aggregate), finally cause the intensity step-down of filtering material of thermal stability by needling process.In addition, needling density improves, and the contraction of filtering material of thermal stability increases, and the apparent density of filtering material improves, thus filtering material is promoted the arresting efficiency of dust.But the corresponding reduction of the Air permenbility of filtering material, easily cause filtering material to use the pressure loss at initial stage to improve at real machine, finally cause shorten the service life of filtering material, such filtering material of thermal stability is also undesirable.The technique of needle point method of the present invention is exemplified below, but is not limited to following technological process: needling process flow process: fibrous raw material → bale opener → mixed long curtain → first shredding → blending box → smart shredding → air pressure cotton box → carding machine becomes net → cross lapping → acupuncture → trimming package.

The technique of glue spraying method of the present invention is exemplified below, but is not limited to following technological process: fibrous raw material → bale opener → mixed long curtain → first shredding → blending box → smart shredding → air pressure cotton box → carding machine becomes net → cross lapping → rear road laying to required width and thickness → spray adhesive → oven dry → trimming package.When adopting acupuncture or spray-bonding craft to make bondedfibre fabric, optimum fiber fineness is 5-10D.
