Description

The method for sizing of camp bed OXFORD

Technical field

The present invention relates to a kind for the treatment of process of fabric, be specifically related to a kind of method for sizing of camp bed OXFORD.

Background technology

OXFORD is as a kind of fabric of high strength, also be widely used in except daily case and bag in the outdoor goods such as tent and camp bed, the high strength of OXFORD itself can keep long-term effectively under indoor environment, but out of doors under service condition, be subject to sunshine direct projection, thermal shock, and light, heat, wet comprehensive function, easily cause fading of dyestuff to decline with the intensity of fabric fibre, at present the weather resisteant adopting the mode of coating to strengthen OXFORD more.No matter adopt roller coat or the mode sprayed, the complexity of its equipment, technique is all higher.And clothes arrange the sizing technique operation relative ease of the maturation adopted at present, but formula of size significantly can increase the weight of fabric, and to fabric intensity, the humidification of surface coverage is limited, limits application.

Summary of the invention

Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides the high method for sizing that also can increase the camp bed OXFORD of fabric intensity of a kind of coverage rate.

Technical scheme: for solving the problems of the technologies described above, the method for sizing of camp bed OXFORD provided by the invention, comprises the following steps:

1) preparation of performed polymer, by the polyethylene glycol 3 ~ 6 parts according to weight proportion, ethyl acrylate 0.7 ~ 2 part, polyvinyl acetate 4 ~ 7 parts, toluene di-iso-cyanide ester 1 ~ 3 part, adds reactor, add 10 ~ 15 parts of acetone and make solvent, stirring is warming up to 70 DEG C of reaction 4h and obtains performed polymer;

2) preparation of slurry, by the weight ratio thin up of step 1) gained performed polymer according to 1:50 ~ 70, and add in solution after dilution percetage by weight be 2% ~ 4% crosslinking agent obtain slurry;

3) preliminary treatment of OXFORD, adopts the N-methyl oil acylamino-ethylsulfonic acid sodium water solution of 2% to carry out rinsing to OXFORD;

4) slashing operation, immerses step 2 by OXFORD rinsed for step 3)) in the slurry prepared, heat slurry and maintain the temperature at 40 ~ 60 DEG C, dip time is 1.5 ~ 3h;

5) suspension drains, and the OXFORD after dipping is hung on the top of heating tank, utilizes heating tank to reclaim slurry, utilizes gravity-flow ventilation to dry.

As preferably, the temperature of flooding in step 4) is 50 DEG C.

As preferably, in described slurry, the concentration of crosslinking agent is 3%.

Beneficial effect: the present invention adopts the method for operating of starching to arrange OXFORD, simplifies the technique of arrangement, and after process, weight increases few, coverage rate is high, and humidification is remarkable.

Detailed description of the invention

2) preparation of slurry, by the weight ratio thin up of step 1) gained performed polymer according to 1:50, and add in solution after dilution percetage by weight be 2% crosslinking agent obtain slurry;

3) preliminary treatment of OXFORD, adopts the N-methyl oil acylamino-ethylsulfonic acid sodium water solution of 2% to carry out rinsing to OXFORD;

4) slashing operation, immerses step 2 by OXFORD rinsed for step 3)) in the slurry prepared, heat slurry and maintain the temperature at 60 DEG C, dip time is 3h;

5) suspension drains, and the OXFORD after dipping is hung on the top of heating tank, utilizes heating tank to reclaim slurry, utilizes gravity-flow ventilation to dry.

Embodiment 2

Get the 420D OXFORD of 2m*2m, adopt following steps to carry out starching:

1) preparation of performed polymer, by the polyethylene glycol 6 parts according to weight proportion, ethyl acrylate 2 parts, polyvinyl acetate 7 parts, toluene di-iso-cyanide ester 3 parts, adds reactor, adds 15 parts of acetone and makees solvent, and stirring is warming up to 70 DEG C of reaction 4h and obtains performed polymer;

2) preparation of slurry, by the weight ratio thin up of step 1) gained performed polymer according to 1:70, and add in solution after dilution percetage by weight be 3% crosslinking agent obtain slurry;

3) preliminary treatment of OXFORD, adopts the N-methyl oil acylamino-ethylsulfonic acid sodium water solution of 2% to carry out rinsing to OXFORD;

4) slashing operation, immerses step 2 by OXFORD rinsed for step 3)) in the slurry prepared, heat slurry and maintain the temperature at 50 DEG C, dip time is 1.5h;

5) suspension drains, and the OXFORD after dipping is hung on the top of heating tank, utilizes heating tank to reclaim slurry, utilizes gravity-flow ventilation to dry.

Wherein crosslinking agent can be the conventional various crosslinking agents in this area, as based on 1,3-dihydroxymethyl-4,5-dihydroxy ethylene carbamide resin (DMDHEU) and derivative thereof.

Weigh before and after starching process, test intensity, obtain data as follows:

	Before process	Embodiment 1	Embodiment 2
				Weight	402g	410g	413g
Tensile strength	198NT	220NT	241NT

Visible, the weightening finish of method for sizing of the present invention to OXFORD is not obvious, effectively improves tearing strength and fracture strength.
