Description

A kind of wrinkle resistant soft finishing agent at soybean fiber fabric

Technical field

The present invention relates to field of fabric producing technology, in particular, is a kind of post-finishing agent that soybean fiber and BLENDED FABRIC thereof is carried out wrinkle resistant soft treatment.

Background technology

Soybean fiber quilt is called the new century " ecological spinning fiber ", and main raw material comes from soybean meal, and its fibre single thread fiber number is thin, and proportion is little, the strength and elongation height.The main component of soybean fiber and cashmere, silk like are seemingly, it is a kind of aftergrowth azelon, contain 18 seed amino acids and carbohydrate, inorganic matter, vitamin etc., owing to contain the hydrophily gene mostly on these amino acid whose molecular structures, make feel as the existing cashmere of soybean fiber, softness and gloss as the silk have the mechanical performance of synthetic fiber and good hygroscopicity and lead moist again, its drapability is also splendid, gives elegant sensation free from vulgarity; With the fabric that high grade yarn is made into, surface pattern is carefully clean, clear, is high-grade underlinen fabric, wears very comfortable.Pay close attention to today of quality of life, health awareness more the mankind.Its appearance had both met the trend that clothes are non-ironing, can wash, and had satisfied the pursuit of people to comfortable and easy to wear, attractive in appearance and healthy green again, will bring new selection to people, led one " green agitation ".

Although the knit fabric that with the soybean fiber is raw material has many advantages, also occurred in use some defectives as: coefficient of friction is little, elasticity is little, shrinking deformation is big, thermo-labile, easy fluffing, wrinkle resistance difference or the like.

At present, on the market there be much the crease proofing agent of fiber species, as: silicone based, epoxy resin, water-based polyurethane, polycarboxylate class or the like, but they are to the wrinkle resistant soft treatment of soybean fiber and BLENDED FABRIC and be not suitable for, and mainly are because permeability, adhesiveness and film forming are unsuitable for the molecular structure of soybean fiber.Therefore, its proprietary wrinkle resistant soft finishing agent that is used for soybean fiber and BLENDED FABRIC is not found as yet in the market.

Summary of the invention

The objective of the invention is to, overcome the defective of the wrinkle resistant soft finishing agent of above-mentioned textiles, provide a kind of, non-environmental-pollution nontoxic, security good to human body, have good hygroscopicity and gas permeability, fabric color, whiteness are not had the wrinkle resistant soft finishing agent that soybean fiber and BLENDED FABRIC are handled that is exclusively used in of influence, soft, wrinkle resistant good endurance.

The objective of the invention is to be achieved by the following technical programs:

A kind of wrinkle resistant soft finishing agent at soybean fiber fabric is characterized in that it is made up of following raw material:

Glyoxal 1-30g/L;

MgCl ₂·6H ₂O 1-18g/L；

Aqueous polyurethane concentration 0.2-20%;

Triethanolamine 0.01-5%;

Softener ZH-S40 1-40g/L;

Penetrating agent JFC 1-10g/L;

Wherein, regulate pH4.5-5 with acetic acid; Can any ratio water-soluble be colourless to light yellow solution.

The prescription of preferable wrinkle resistant soft finishing agent is as follows:

Glyoxal 5-20g/L;

MgCl ₂·6H ₂O 5-10g/L；

Aqueous polyurethane concentration 1-10%;

Triethanolamine 0.1-5%;

Softener ZH-S40 5-25g/L;

Penetrating agent JFC 1-5g/L.

The prescription of even more ideal wrinkle resistant soft finishing agent is as follows:

Glyoxal 18g/L;

MgCl ₂·6H ₂O 8g/L；

Aqueous polyurethane concentration 8%;

Triethanolamine 1%;

Softener ZH-S40 20g/L;

Penetrating agent JFC 2g/L.

Soybean fiber fabric of the present invention generally refers to soybean fiber and forms BLENDED FABRIC with materials such as cotton, fiber crops, hair, cashmere, artificial fibres, wherein the textiles that mixes with cashmere with soybean fiber adopts finishing agent of the present invention to handle its wrinkle resistant soft effect the best.

Penetrating agent JFC of the present invention is meant undressed commercial goods, and it refers to fatty secondary alcohol polyoxyethylene ether, belongs to nonionic surface active agent, as JFC-1, JFC-2 etc.

Softener ZH-S40 of the present invention by: amido silicon oil, alkyl phenol, fatty alcohol polyethenoxy ether class, alkylphenol polyoxyethylene class and deionized water are formed.Wherein said alkyl phenol, fatty alcohol polyethenoxy ether class are: its carbon number is 3-12 fatty alcohol polyethenoxy ether class such as AEO-4, AEO-7, AEO-9 etc., and carbon number is a 3-12 alkylphenol polyoxyethylene class, as OP-4, OP-7, OP-10 etc.Softener ZH-S40 optimum formula is by: amido silicon oil 45 grams, OP-7 10 grams, and AEO-4 5 grams, deionized water 100 grams are formed, and are made into clear microemulsion solution after mixing.

Owing to contain more active group in the wrinkle resistant soft finishing agent provided by the invention, as amino, hydroxyl, phenolic hydroxyl group, acylamino-etc. can with active group reaction in the natural fabric molecules such as soybean fiber and BLENDED FABRIC, cotton, wool, cashmere, especially good intermiscibility and adhesion are arranged with soybean fiber and BLENDED FABRIC.When fabric being carried out the back arrangement, in oven dry and the dehydration of training baking stage, the intermolecular formation of finishing agent and soybean fiber is partial cross-linked, perhaps this finishing agent is penetrated into the deposition curing of the fine place of fiber, has increased intermolecular frictional resistance, gives soybean fiber and BLENDED FABRIC good do, wet pincher elasticity and washability, it is constant that fabric size keeps, wrinkle resistance is also very outstanding, and easily washes, does soon, is a kind of desirable " green " wrinkle resistant soft finishing agent.

This finishing agent generally adopts conventional method to comprise that step is as follows to the technology of soybean fiber and BLENDED FABRIC arrangement thereof: soybean fiber and BLENDED FABRIC thereof are handled with diluted acid, for example organic acid such as acetic acid, formic acid is pressed bath raio: 1: 20 adding soybean fiber fabric during use.Two soak two roll, 2.0 * 10 ^-3Ml/L, pick-up 96%, two soak two and roll dressing liquid, room temperature, and pick-up is 98%, preliminary drying (70 ℃ * 5min) bake (100 ℃ * 4min) soap (2g/L soap powder, 30 ℃ * 15min) oven dry (70 ℃ * 5min) normal temperature cooling.This operation also is suitable for one and soaks and one roll, two soak one and Collator Mode such as roll.

To textiles, after particularly soybean fiber and BLENDED FABRIC thereof were handled, textiles had significant good effect with wrinkle resistant soft finishing agent provided by the invention: do not contain formaldehyde, and non-stimulated to human body; Doing, wet, it is all higher (dried: 193-258 to play recovery angle; Wet: 145-220, measurement standard: GB3819-83), whiteness is unaffected substantially, and pliability improves, and washability is good.Table 1 is a test result, wherein does, wets and rebound multiple angular measurement test-object standard with reference to GB3819-83; The drapability testing standard is with reference to FJ539-76; The gas permeability testing standard is with reference to GB5453-85.Table 1

Sample title situation project testing	The fabric former state	After the textile finishing
			Creasy recovery angle (degree) (do, wet)	193 (doing) 145 (wetting)	258 (doing) 220 (wetting)
(do, the wet) creasy recovery angle (degree) of soaping 50 times	193 (doing) 145 (wetting)	240 (doing) 210 (wetting)
			Suspended coefficient (%)	30	31
Gas permeability (cc/cm 2/s)	361	349

Soybean fiber and BLENDED FABRIC thereof after wrinkle resistant soft finishing agent is handled as can be seen from Table 1 done, wet crease recovery angle (degree) increases, and the elasticity raising of fabric is described, wrinkle resistance is good; Crease recovery angle after soaping is constant substantially, illustrates that the crease-resistant washability persistence of fabric is good; And that the suspended coefficient of fabric, gas permeability change is little, this shows soybean fiber and BLENDED FABRIC thereof after wrinkle resistant soft finishing agent is handled, kept soft, smooth, lead wet, ventilative, warming, electrostatic effect is little, sun-proof, anti-ly damage by worms, anti-mould, characteristic that drapability is good, comfortable and easy to wear.
