CN1174139C - Dipping liquid for increasing strength of raw silk - Google Patents

Abstract

The present invention relates to a dipping aqua for improving the strength of raw silk, which is used for dipping treatment before weaving the raw silk. The aqua is prepared from refined vegetable oil or mineral oil, one or more kinds of polyoxyethylene alxylphenol ether, sorbitol fatty acid ester, polyoxyethylene 20 sorbitan fatty acid ester, one or more kinds of anionic surfactants, silicon latex, antistatic agents, water, etc. The present invention has the advantages of long storage time, low dosage, low cost for dipping per unit of raw silk, favorable clarification of the dipping liquid after the raw silk is dipped, favorable permeability, etc., can not only be used for traditional dipping in a round vat and dipping in a square tank, but also can be used for dipping in automatic silk damping equipment.

Description

A kind of dipping liquid that improves strength of raw silk

The present invention relates to a kind of dipping liquid that improves strength of raw silk, be used for the preceding impregnation process of raw silk weaving.

Raw silk must by dipping, be given organizine with flatness and ABRASION RESISTANCE through impregnation process before weaving, give tram with flexibility.Simultaneously,, make the strand retraction, improve TENSILE STRENGTH and elongation at break, reduce the internal stress in the silk process because the dipping auxiliary agent infiltrates raw silk inside; Also can eliminate at preparatory construction and weave the static that produces in the engineering, be convenient to weave smoothly.It is the oiling treatment agent of feature with the cationic surfactant that Chinese patent CN1040465C discloses a kind of.Though this auxiliary agent good penetrability, because the scouring assistant of silk is based on anion, the cation easily in this finishing agent combines the reduction scouring result with anion in the scouring assistant.And at present a lot of commercially available aquas, though based on anion and non-ionic surface active agent, owing to cooperate unreasonable, finishing agent is being joined when diluting in the dip tank, or have flocculent deposit to separate out, or have grease swim in cylinder above, be unfavorable for the dipping; Maceration extract behind the dipping raw silk is muddy, the wastewater treatment trouble.In addition, some auxiliary agent is placed for a long time, particularly summer, is easy to generate and goes mouldy.

The purpose of this invention is to provide a kind of dipping liquid that improves strength of raw silk, shortcoming at existing commercially available silk damping aqua, optimization of C reasonably, the organizine property endured, flatness behind the dipping are improved, intensity improves, the flexibility of tram increases, and the maceration extract behind the dipping is still clarified.

The dipping liquid of the raising strength of raw silk that the present invention selects has following component (percentage by weight):

(1) 5%～50% refined plant oil or mineral oil, wherein vegetable oil is soybean oil, cottonseed oil, rapeseed oil, palm oil, coconut oil, mineral oil is machinery oil, bobbin oil, refining white oil;

(2) 0.5%, the alkane of one or more of 20% is for phenol polyethenoxy ether, and wherein alkyl is octyl group, secondary octyl, nonyl etc., oxyethylene group (CH ₂-CH ₂O-) the degree of polymerization is 2-50;

(3) 0.5%～20% D-sorbite fatty acid ester;

(4) 0.5%～20% polyoxyethylene sorbitan fatty acid ester;

The anion surfactant of one or more of (5) 0.5%～5% is as sodium alkyl sulfate, sodium alklyarylsulfonate, sodium alkyl sulfonate;

(6) 0.5%～20% silicon breast is as hydroxy silicone emulsion, amino silicon breast, silicone emulsion;

(7) 0.1%～2% antistatic additive;

(8) 5%～90% water;

The present invention puts each component together by above-mentioned prescription, fully mixed milky body of paste or the emulsion of getting under the room temperature.

The dipping liquid of the raising strength of raw silk that employing is made by the present invention is handled the raw silk of different purposes by following method.

1) traditional cylinder impregnation and square-groove impregnation technology

(temperature of water is generally 34～40 ℃ in that 300 kilograms of running water or distilled water are housed, decide with weather conditions) soak the silk damping aqua (concentration of body lotion is about 0.1%～2%) that makes by the present invention that adds 0.3～6 kilogram in the cylinder, after fully stirring, scoop out about 50 kilograms body lotion with bucket, directly in cylinder, add behind 60 kilograms the raw silk again to the body lotion of going into to scoop out, flooded oven dry again after the dehydration 30～60 minutes.

2) impregnation technology on the automatic silk soaking machine equipment

A. centrifugal automatic silk soaking machine: first silk dipping auxiliary dosage 1-6 kilogram, temperature 34-40 ℃, dip time 20-50 minute, later on second and third, four, five silks dippings only add 0.25-1 kilogram auxiliary agent.

B. adding pressure type automatic silk soaking machine: per 20 kilograms of silks, auxiliary dosage 0.5-3 kilogram, dip time 5-15 minute.

The dipping liquid storage time of the raising strength of raw silk of the present invention's preparation is long, not stratified, does not go mouldy; Consumption is low, and the required expense of dipping unit raw silk is low; Nontoxic pollution-free, maceration extract is clarified behind silk damping; Good penetrability, flexibility, flatness improve behind the silk damping, and intensity increases.
