Description
Technical Field
The invention relates to the technical field of fabric processing, in particular to a carbon sanding process for all-cotton poplin.
Background
The poplin is a plain fine fabric woven by cotton, polyester, wool and cotton-polyester blended yarns, and is a plain cotton fabric with fine texture, smoothness and glossiness. As the warp density of the poplin is obviously larger than the weft density, diamond grains formed by the raised parts of the warp yarns are formed on the surface of the fabric. The poplin fabric is woven by using pure cotton or polyester cotton fine yarn.
The poplin is made up by using warp and weft yarns with uniform yarn levelness, weaving them into grey cloth with compact structure, singeing, refining, bleaching, printing, dyeing and finishing. The poplin fabric has the characteristics of clean and flat cloth cover, fine texture, full grain, bright, smooth and soft luster and the like, is suitable for being used as clothes such as shirts, coats and the like, and can also be used as embroidery base fabric. The poplin is divided into warp and weft yarn raw materials, such as common poplin, fully combed poplin, half-line poplin and the like; the weaving patterns are divided into hidden-stripe hidden-lattice poplin, satin stripe satin lattice poplin, jacquard poplin, yarn-dyed poplin, color stripe color lattice poplin, flash color poplin and the like; the printing and dyeing processing is divided into bleached poplin, variegated poplin, printed poplin and the like; some varieties are also finished by rain-proof, non-ironing, shrink-proof and the like. The above various poplin uses pure cotton yarn as raw material, so that the all-cotton poplin is knitted.
Because the cloth surface of the all-cotton poplin is too smooth and tight, the all-cotton poplin is easy to feel stiff and dry, and the quality of the all-cotton poplin is affected.

The present invention in a preferred example may be further configured to: the carbon grinding rod comprises the following components in parts by weight: 50-70 parts of modified ceramic powder, 20-30 parts of resin and 10-20 parts of carbon fiber.
By adopting the technical scheme, the ceramic powder has the advantages of high strength and strong wear resistance, the ceramic micro powder is an inert material and has good corrosion resistance and chemical stability, and the grinding rod made of the ceramic micro powder has longer service life; the carbon content of the carbon fiber is more than 90 percent, the carbon fiber is a fiber with high strength and high modulus, the high temperature resistance of the carbon fiber is the first of chemical fiber, but the carbon grinding rod prepared by singly using the carbon fiber has poor grinding effect;

a4. and carrying out curing compression molding treatment on the preformed product to obtain the nitrile rubber/phenolic resin.
The present invention in a preferred example may be further configured to: the cloth feeding tension in the step 1 is 0.3-0.5 MPa.
By adopting the technical scheme, the cloth feeding tension is as large as possible in a proper range, the higher the tension is, the tighter the fabric is contacted with the grinding rod, the deeper the sand grains on the surface of the carbon grinding rod are embedded into the fabric, the more the effective sand grains are, the more fibers are hooked, and the better the sanding effect is; however, the degree of damage to the fabric due to excessive tension is also large, and wrinkles are easily generated on the fabric, so that the tension should be controlled within a proper range.
The present invention in a preferred example may be further configured to: the pressure of the grinding rod in the step 1 is 15-25 Kg.
Through adopting above-mentioned technical scheme, the size of surface fabric cladding angle on the grinding rod can be influenced to the size of grinding rod pressure to and the contact surface size on fabric and grinding rod surface, and pressure is big more, and area of contact is big, and the sanding effect is better, but when pressure was too big, the easy fraying of fabric, consequently, need be with grinding rod pressure control in suitable within range.

By adopting the technical scheme, the larger the difference between the rotating speed of the grinding rod and the advancing speed of the fabric is during sanding, the shorter, dense and uniform fuzz is easy to generate, and the fabric surface of the fabric is plump; on the contrary, the produced fuzz is long and thin, and the hand feeling is hard. However, the larger the difference between the speeds of the two, the more the strength of the fabric to be reduced by the sanding machine is, and therefore, both the speeds need to be controlled within a proper range.

Performance test
All-cotton poplin produced in examples 1 to 12 and comparative examples 1 to 6 were sampled, and the samples were subjected to the following property test tests.
Hand feeling detection: randomly selecting 100 passers to respectively touch the 18 groups of samples, and recording the touch handfeel; the number of soft pedestrians recorded in each group of samples was divided by the total number of pedestrians to obtain the softness, the hand feeling of the samples was represented by the softness, and the softness was recorded in table 1.
And (3) observing the quality of the sample: and (3) observing the cloth surface condition of each group of samples by naked eyes by taking whether the samples have wrinkle marks, streaks, broken holes and whether the fluff is flat and uniform as indexes, and recording the observation results in the table 1.
TABLE 1-various Performance test indexes of the samples
From the sample detection data in table 1, it can be seen that:
the sanding process is favorable for improving the touch softness of the all-cotton poplin;
the sanding effect of the carbon grinding rod is better than that of the carbon fiber grinding rod;
the cloth feeding tension, the pressure of the grinding rod, the advancing speed and the rotating speed of the grinding rod in the grinding process have certain influence on the grinding quality of the all-cotton poplin, so the parameters need to be controlled in a proper range;
the sanding effect of the sanding bar made of titanium dioxide/alumina composite powder is better than that of the sanding bar made of alumina powder;
the sanding effect of the sanding bar made of the nitrile rubber/phenolic resin is better than that of the sanding bar made of the phenolic resin;
the sanding effect of the sanding bar made of the added copper-chromium alloy powder is better than that of the sanding bar made of the powder without the added copper-chromium alloy powder.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
