Abstract
The present invention relates to a silkworm chrysalis albumen spinning solution, which contains silkworm chrysalis albumen, acrylamine or acrylonitrile, soft water, sodium hydroxide and oxydol. The solution is conditionally co-mixed with TVA, viscose, orlon, etc. for spinning.
Description
The present invention relates to the new material and the manufacture method thereof of textile industry, particularly silkworm chrysalis albumen spinning solution body and manufacture method thereof.
At present, with soybean protein, peanut protein, zein is raw material, the albumen spinning solution body of making carries out spinning, all too low because of its fiber wet strength of making, and eliminated by other fibers, composite fibre is made in people's albumen spinning solution spinning of attempting again making with the milk casein then, but the milk casein costs an arm and a leg, the production cost height.And China has a large amount of silkworm chrysalises, and as the waste material of silk weaving, great majority are used as feed and fertilizer, and contains a large amount of available natural pupa albumen in the silkworm chrysalis.In the prior art, people utilize silkworm chrysalis to extract pupa protein production food, tonic beverage, compound amino acid etc., and extract the pupa casein process hides with silkworm chrysalis, (see the open CN1071209A of Chinese invention patent with the pupa protein liquid spinning that pupa casein is made, inventions such as the inventor), but its technological process is long, the PVA shrinkage is big, and hygroscopicity is bad, and dyeability is bad.
The object of the present invention is to provide a kind of silkworm chrysalis albumen spinning solution that utilizes pupa albumen to make, can with co-blended spinnings such as PVA, viscose glue, acrylic fibers.
Silkworm chrysalis albumen spinning solution body of the present invention includes pupa albumen 15～20%, acrylamide or acrylonitrile 1.5～6%, soft water 77～80%, NaOH 0.7～4%, hydrogen peroxide 0.05～0.1%.The process for making of this silkworm chrysalis albumen spinning solution body is as follows:
(1) with molecular weight between 1～80,000, protein content is at the pupa albumen more than 75%, put into temperature and be 60 ± 5 ℃ soft water rinsing repeatedly, up to the abundant swelling of pupa albumen, the pH value of rinsing liquid is 6～7, dehydration then obtains the pupa albumen after the rinsing.
(2) press pupa albumen: NaOH=1: 0.08～0.2 (solid weight ratio), it is that 60 ± 5 ℃, concentration are in the sodium hydrate aqueous solution of 1.2～2% (weight ratios) that pupa albumen after the rinsing is dissolved in temperature, constant temperature stirred 3～5 hours, obtained pupa albumen liquid.
(3) above-mentioned pupa albumen liquid is cooled to 40～45 ℃, after the hydrogen peroxide of adding 0.05～0.1% causes, press pupa albumen again: acrylamide or acrylonitrile=1: 0.1～0.3 (solid weight ratio) adds acrylamide or acrylonitrile, obtains the silkworm chrysalis albumen spinning solution body through fully stirring.
The present invention has the following advantages and effect:
Pupa albumen for spinning, under alkali condition, dissolubility is good, and its solution viscosity is stable, and same PVA, viscose glue, acrylic fibers etc. have common solvent, the co-blended spinning of having ready conditions.
The manufacture method of silkworm chrysalis albumen spinning solution body provided by the invention turns waste into wealth silkworm chrysalis, has made full use of the protein resource of China, has promoted COMPREHENSIVE UTILIZATION OF SILKWORM CHRYSALIS.
Below the invention will be further described with embodiment.
