Abstract
The invention provides special denim size and a preparation method and application thereof. The starch and modified starch size needs boiling and braising for about an hour, and at the same time, higher size temperature needs maintaining during sizing, thus the energy consumption is higher. The special denim size comprises the following components in parts by weight: 70-90 parts of polyurethane, 7-9 parts of polyacrylic ester, 3-5 parts of smoothing agent, 3-5 parts of amphipathic silicone oil, 1-3 parts of low-temperature crosslinking agent and 1-3 parts of acrylate-methacrylate thickening agent. The special denim size is used for dyeing and sizing denim warps.
Description
Technical field:
invention relates to a kind of extraordinary slurry of cowboy, preparation method and its usage of the cowboy's of being used for warp sizing.
Background technology:
are present, and the slurry of sizing part is all selected starch, converted starch for use in cowboy's warp thread sizing-dyeing machine, and emulsification butter, PVA, glue, emulsifying wax etc. are as the starching raw material.The stewing slurry of mashing off back is through the effect of padding: infiltration and being overlayed on the yarn, and improve the tensile strength and the smooth property of yarn, thereby when weaving cotton cloth, reduce the broken end of yarn, improve loom efficient etc.Although through the technological improvement of nearly half a century, all oneself solves problems such as the feature of environmental protection and environment friendly to above-mentioned slurry, also can reach and improve yarn strength and the problem that improves loom efficient, when practical application, also has a lot of shortcomings.
for example: act on single problem, as the yarn slurry, starch, converted starch, emulsification butter, glue, emulsifying wax etc. all belong to very easily water-soluble water-soluble substances.After the yarn sizing, only can improve yarn strength and reduce broken end, improve loom efficient, but weave next cloth, cloth cover is coarse, also need pass through destarch or mercerized finish, is unfavorable for reducing technological process, energy-saving and emission-reduction.After slurry has all moved back simultaneously, can not reach and improve yarn luster degree, the purpose of compliance and COLOR FASTNESS.
conventional method energy consumption is bigger, and starch and converted starch class slurry all need about one hour mashing off, and stewing slurry all need keep higher slurry temperature during starching simultaneously, so energy consumption is higher.
owing to above-mentioned technology, the COLOR FASTNESS of formation is lower.Because the higher temperature of process in the starching process; Indigo dye on slurry and the yarn or SULPHUR DYES have certain oxidation polymerization, be made into cloth after owing to need through the destarch arrangement; Slurry takes off also can take off when moving back and moves back the part dyestuff, causes the not enough color of color fastness to shoal.Also restricted simultaneously the application of follow-up garment wash technology.
Summary of the invention:
The purpose of
invention provides a kind of combination reaction that need not carry out complicacy, and production technology is simple, the preparation method and the application thereof of the extraordinary slurry of the cowboy of constant product quality.
Above-mentioned purpose realizes through following technical scheme:
