Abstract
The invention relates to dying project field for weaving industry manufacturing, especially relates to fixed island type island short fiber separating technology. Fixed island type island short fiber is a new kind fiber, when using the normal fiber separating method to take separating processing, and the PET island fiber would be decomposed. The invention supplies a fixed island type island short fiber separating technology that is low energy consumption, little sewage to release, and low harm to fiber. Separating agent is used in the method.
Description
Technical field
The present invention relates to the dyeing and finishing engineering field of caused by spinning industrial production, relate in particular to a kind of fiber opening process of figured islands-in-sea short fiber.
Background technology
Sea-island composite fiber has begun commercialization production in Japan as far back as the sixties in 20th century, and worldwide maintains the leading position always.China begins the production of islands-in-sea type fibre in the nineties in 20th century.But be filament fiber basically.
The superfine islands-in-sea bicomponent staple fibre is divided into figured type and figured type not, island ultrafine fiber is not a sea component with high polymers such as polystyrene usually, utilize the incompatibility of two kinds of high polymer moltens to form the island in the fibre section and distribute, go sea component is molten with solvent, fiber is mainly used in the footwear synthetic leather.
The figured islands-in-sea short fiber is the novel kind of research and development in nearly 2 years, the figured islands-in-sea short fiber reaches below the 0.06dtex owing to its fibre fineness, so counter-bending rigidity is low, have soft, drapability good, hygroscopicity significantly improves, and than fabric of island-in-sea type long filament better bulkiness, flexibility, hygroscopicity arranged.The figured islands-in-sea short fiber applicable to purely spin, also can with synthetic fiber, natural fibre blended, interweave, opened up the mutual supplement with each other's advantages between the fiber greatly, can improve the qualities such as gloss, feel, brute force, outward appearance of fabric, be applied to novel high-grade wearing fabric.Its adaptability is more extensive, at non-weaving cloth and garment material application facet vast market prospect is arranged.
Figured islands-in-sea short fiber structure is 3D38mm, 3D51mm, 4D51mm etc.Sea/island is than 37/63.Marine origin part is COPET (water-soluble polyester), and the island composition is PET (polyester).In the fibre section decentralized photo PET be " island " state parent COPET then+be equivalent to the state in " sea ".Every fiber has 37 islands.
Fiber opening process is crucial link in the dyeing and finishing technology of islands-in-sea type fibre, opens fibre and promptly by post processing extra large component is dissolved, and remaining is the superfine fibre of one-component, opens outward appearance and inherent quality that fine effect will directly have influence on finished product.
Existing conventional fiber opening process is a high temperature highly basic method, this technology is used for the figured islands-in-sea short fiber when opening fibre, high temperature highly basic is no doubt favourable to the dissolving fully of sea component, but conventional PET island fiber has also been produced decomposition, and the shortcoming of high temperature highly basic fiber opening process is exactly that energy resource consumption is big, sewage discharge is many, fibre damage is big.
Summary of the invention
The object of the present invention is to provide the low alkali fiber opening process of figured islands-in-sea short fiber low temperature that a kind of energy resource consumption is little, sewage discharge is few, fibre damage is little.
Fine agent is opened in the present invention utilization, and designing optimal process conditions, technological parameter through sample repeatedly, obtain the low alkali of low temperature and open fine reliable process, make the low alkali of low temperature can meet or exceed high temperature highly basic and open fine effect.
The invention provides a kind of fiber opening process of figured islands-in-sea short fiber, the present invention is the low alkali fiber opening process of low temperature for conventional fiber opening process, and process conditions are that 98%NaOH 6 is to 8g/l, open fine agent 4 to 6g/l, 80 ℃ to 90 ℃ of temperature, time 20-40 minute, bath raio 1: 15-30.
Wherein open fine agent can be vapour Bagong department, the M-1100 of Hangzhou Meigao Huayi Chemical Industry Co., Ltd.
Fiber opening process of the present invention obtains by following repeatedly sample:
One, sample fabric:
Figured islands-in-sea short fiber 3D51mm 100% knitting single jersey that Shanghai Institute of Synthetic Fiber produces.
Two, test sample devices:
Normal temperature and pressure dyes model machine
Three, sample auxiliary agent:
Open fine agent printing and dyeing assistant
The commercially available analysis of NaoH is pure
Four, sample technology preparation:
1, existing conventional fiber opening process
98%NaOH temperature-time bath raio
100 ℃ of 15g/l 30 minutes 1: 20
2, the low alkali of low temperature is opened fine sample combination
Bath raio 1: 20
98%NaOH opens fine agent temperature-time
100 ℃ of 10g/l 8g/l 40 minutes
90 ℃ of 8g/l 6g/l 30 minutes
80 ℃ of 6g/l 4g/l 20 minutes
Five, coupon results
A、NaOH
From 6g/l to 10g/l, increase the molten increase of alkali, but the above increase of 8g/l consumption is not obvious with concentration.
B, open fine agent
From 4g/l to 8g/l, increase the molten increase of alkali, but the above increase of 6g/l is not obvious with concentration.
C, temperature
With the molten increase of temperature rising fabric alkali, but increase not obvious more than 80 ℃.
D, time
The time lengthening from 20 minutes to 40 minutes and the molten increase of alkali, alkali was molten more abundant in 30 minutes.
E, conventional fiber opening process:
Weight-loss ratio 34.8% is opened fine rate 93.3%, decreases 6.5% by force
F, the best fiber opening process of the low alkali of low temperature:
At 98%NaoH 8g/l, open fine agent 6g/l, 80 ℃ of temperature, under the 30 minutes time process conditions, weight-loss ratio 34.6% is opened fine rate 94.1%, decreases 0.3% by force
Beneficial effect of the present invention is as follows:
1, open fine agent by use, the NaoH consumption can reduce by 46.6%, and temperature drops to 80 ℃ by 100 ℃, the molten weight-loss ratio of alkali with open fine rate and all meet or exceed routine and open fine effect.
2, owing to the client can be adjusted accordingly feel, the molten fiber opening process of appearance requirement Different Alkali of island short fibre fabric, but the low alkali of low temperature is practical.
3, facts have proved that but low temperature hangs down alkali fiber opening process energy efficient, auxiliary agent reduces cost.And split fine effect better controlled can be arranged.
4, open fine agent by use, fabric strength is largely increased, for the strength damage of back road sanding operation provides basic guarantee.
The present invention has good society and economic benefit.
