The cotton fabric rationality energy before and after the processing of table 1
By table 1 and Fig. 1-2 it is found that the method for the invention can lead to acrylic ester monomer and improved silica
It crosses electron radiation technology to be grafted on cotton fabric, the fabric (embodiment 1-3) that the method for the invention arranges has preferable quiet
State water contact angle, resistance to water drenching performance and resistance to hydrostatic pressure performance, and after being equivalent to average family washing of drum type washing machine 30 times, preparation
Fabric still there is extraordinary hydrophobic performance.It can also be seen that the cotton fabric (embodiment 3 for not adding silicon ball by the table
1) with control, hydrophobic effect is modified the finishing effect of silicon ball significantly lower than adding, and adds the titanium dioxide modified without double bond
The finish fabric of silicon silicon ball does not have any hydrophobic effect (embodiment 3 and control although hydrophobic effect is good before washing after washing
2), show that silica can not be chemically grafted to cotton fabric, only physical attachment, fall off after washing, while taking away low-surface-energy
Acrylate analog assistant, cause fabric restore hydrophily.
The uniformity test of cotton fabric hydrophobic effect: 5 different locations of sample test after managing are rounded according to embodiment 3
Static water contact angles, fluctuation range be 152 ± 4 °, there is not water droplet penetration phenomenon in sample, and hydrophobic effect is preferable.This
Outside, other schemes of Examples 1 to 2 are repeated, as a result almost the same with table 1, fluctuation range very little.
The reperformance test of cotton fabric hydrophobic effect: the hydrophobic cotton fabric prepared according to embodiment 3 arranges 10 in batches
It is secondary, the Static water contact angular region of every batch of sample is tested at 152 ± 5 °.In addition, other schemes of Examples 1 to 2 are repeated,
As a result almost the same with table 1, fluctuation range very little.
Embodiment 5: influence of the technique to hydrophobic effect
(1) esters of acrylic acid concentration
Fixed modified silicon spherolite diameter is 200nm, and when octadecyl acrylate concentration is 5%, contact angle reaches 145 °, has
Preferable hydrophobic effect；With the increase of octadecyl acrylate concentration, contact angle is gradually increased, when concentration is 30%, contact
Angle reaches 152 °；Continue to increase octadecyl acrylate concentration, fabric hydrophobic effect is basically unchanged after arrangement.But since monomer is dense
It spends greatly, in radiative process, monomer autohemagglutination increases, difficulty is caused for subsequent cleaning cloth specimen, meanwhile, the utilization rate drop of monomer
Low, increased production cost.
(2) silicon ball concentration
Securing unit is octadecyl acrylate, when silicon ball mass concentration modified in treatment fluid is 1%, cotton after radiation arranges
Fabric contact angle is lower than 140 °, and main cause is that silicon ball content is less, cannot effectively be covered on fabric surface, can not significantly improve
The roughness of fabric surface, the surface free energy for relying solely on this low-surface energy substance reduction fabric of acrylic ester monomer come
Improve hydrophobic effect.With the increase of modified silicon ball concentration, contact angle increases, and reaches 152 °.Main cause may be modified silicon
Ball increases in the quantity of fabric surface, and Roughness is caused to increase.When modified silicon ball concentration is greater than 10%, contact
Angle does not change substantially.
(3) irradiation dose
When irradiation dose is crossed lower than 16kGy, the hydrophobic effect of fabric is poor, and main cause is that radiation energy is too low, insufficient
To cause acrylic ester compound and the graft polymerization reaction containing double bond modified silicon ball and cotton fabric, affects hydrophobic monomer and exist
The covering of fabric surface, grafting rate are lower.When dose of radiation is more than 65kGy, monomer homopolymerization increases, and system viscosity increases, together
Sample can have an adverse effect to hydrophobic effect.Moreover, radiation not only can excitation fiber, monomer and modified silicon ball occur it is anti-
It answers, also can act on cellulose, when radiation energy is excessive, cellulose molecular chain is broken, and is caused under fabric mechanics
Drop.
Although present invention preferred embodiment discloses as above, it is not intended to limit the invention, any to be familiar with this technology
People can all do various change and modification, therefore protection scope of the present invention without departing from the spirit and scope of the present invention
It should subject to the definition of the claims.
