Embodiment 1

[0016] Embodiment 1: take sisal as raw material to prepare carpet

[0017] 1. Dyeing process:

[0018] First put the divided hemp into the vat to be dyed, then add water and dye to mix. Then, put the vat to be dyed into the main dyeing vat, heat up, and start to keep warm and fix the color when the temperature reaches 60 degrees Celsius. Generally, light colors need to be kept warm for 30 minutes, and dark colors need to be kept warm for 60-90 minutes. Then wash the dyed raw materials for 1-2 days. times to remove unpigmented dye. Afterwards, dehydrate the dyed sisal, and then dry it at 110, 130, and 145 degrees Celsius for three times, each time for about 5 minutes, and the moisture content after drying is below 13%.

[0019] 2. Spinning process:

[0020] 1) Rima

[0021] Divide the dyed sisal in units of 1 kg. The dyed sisal is stretched and combed to make hemp balls, each 175 meters long, and usually combed twice to remove 75% of impurities and hemp bran. The prepared...

Embodiment 2

[0034] Dyeing, spinning and weaving process are identical with embodiment 1.

[0035] 4. Post-processing procedure:

[0036] 1) Preparation of rubber lining

[0037] This foam rubber based on 100 parts by weight contains 35 parts by weight of natural rubber, and 57 parts by weight of calcium carbonate, 2 parts by weight of carbon black, 2 parts by weight of zinc oxide, 0.5 parts by weight of sulfur, 1 part by weight of oil Potassium acid, and the rest are auxiliary materials. Make the density of the glue 230g / L.

[0038] 2) Glue

[0039] Foam the above-prepared glue. In addition, conventional auxiliary materials such as softeners can also be added during foaming. And use a scraper to coat the back of the woven sisal carpet with a thickness of 1mm, and then irradiate with infrared rays to form a semi-dry film. The surface temperature is 300 degrees, irradiated for 25 seconds. Then the patterns are pressed out by pressing rollers to make the rubber surface wear-resistant a...

Embodiment 3

[0041] Dyeing, spinning and weaving process are identical with embodiment 1.

[0042] 4. Post-processing procedure:

[0043] 1) Preparation of rubber lining

[0044] This foam rubber based on 100 parts by weight contains 43 parts by weight of natural rubber, and the calcium carbonate of 49 parts by weight, the carbon black of 3 parts by weight, the zinc oxide of 2.5 parts by weight, the sulfur of 0.8 parts by weight, the oil of 1.6 parts by weight Potassium acid, and the rest are auxiliary materials. Make the density of the glue 500g / L.

[0045] 2) Glue

[0046] Foam the above-prepared glue. In addition, conventional auxiliary materials such as softeners can also be added during foaming. And use a scraper to coat the back of the woven sisal carpet with a thickness of 4mm, and then irradiate with infrared rays to form a semi-dry film. The surface temperature is 300 degrees, irradiated for 35 seconds. Then the patterns are pressed out by pressing rollers to make the rubber...

Abstract

This invention provides a foaming rubber for carpet manufacture. This foaming rubber comprises 35~45wt% natural rubber, 47~57wt% calcium carbonate and some carbon black, zincum oxide, sulfer and potassium oleate. This invention also provides a method for producing bast carpet with wear resistance and embossability with the foaming rubber mentioned above, which comprises pigmentation, spinning, weaving and postprocessing. In the postprocessing step, bast carpet semi-products are coated with the foaming rubber, dried and sulfurated, with an adhesive density range of 160~520g / L and an underlay rubber thickness range of 1~4mm. Bast carpets manufactured with the foaming rubber in this invention performs excellent wear resistance and can be embossed into kinds of figures. Besides, it is also antistatic.

Description

technical field [0001] The invention relates to the field of woven fabric manufacturing, in particular, the invention relates to a foamed rubber used for making carpets and a method for making hemp carpets by using the foamed rubber. Background technique [0002] Carpets are known to consist of a carpet and a backing. China's carpet processing technology has a long history. For a long time, various carpets woven from wool and blends have occupied the carpet consumer market. This is because the process of preparing carpets from wool and blended fabrics is relatively mature, and carpets with various patterns can be woven. But wool and blended carpets have the problem of high cost, thus limiting their widespread popularity. Recently, carpets prepared from hemp, especially sisal and green hemp, have attracted people's attention. This is because such carpets are cheap and suitable for use in hot and humid areas where wool carpets are not suitable. However, hemp carpets have ...
