Background
In recent years, with the vigorous development of domestic real estate and urban construction and the higher requirements of people on living environments, the usage amount of roller brushes (also called roller brushes) for decoration is gradually increased, and the requirements of people on the style and fineness of decoration are more and more strict. At present, rolling brushing velvet is generally used for painting the wall surface, and the requirements of customers on the resilience performance of a roller brush and the hand feeling of the velvet are stricter and stricter.
The existing rolling brushing velvet is generally made of wool, acrylic fibers, polyester nitrile, chinlon and the like, and has various defects. For example, the acrylic fiber rolling brush has a large paint absorption amount, but is easy to fall off, so that the brushing effect is influenced; the nylon rolling brush has no hair falling but high price; some products have uneven suede, poor elasticity and poor antibacterial effect, are uneven when brushed out of the wall or furniture coatings, and influence the house decoration effect. Chinese patent document CN107557899A discloses a process for preparing nylon rolling brush velvet, wherein bristles of the invention are prepared from raw materials such as nylon, and the raw materials in parts by weight are as follows: 100-180 parts of chinlon master batch, 0.05-0.2 part of vitamin C, 0.01-0.7 part of vitamin E, 0.5-2 parts of nicotinic acid, 2-5 parts of jellyfish powder, 8-20 parts of PBT (polybutylene terephthalate) particles, 2-6 parts of nano silver particles, 2-7 parts of nano pearl powder, 2-6 parts of traditional Chinese medicine residues, 2-6 parts of aloe peel dry powder, 3-8 parts of aluminum oxide, 2-7 parts of straw powder, 2-7 parts of kaolin, 0.1-1 part of nano titanium oxide and 0.1-1 part of nano zinc oxide; the nylon rolling brush velvet has good pulp absorption and good antibacterial effect. Chinese patent document CN1776053A (hengtai patent) discloses a process for manufacturing nylon roller brushing velvet, which uses a double-layer rapier loom as a processing tool, nylon as a velvet raw material and terylene as a base fabric raw material, and adopts the procedures of spooling, warping, weaving, combing and sizing. The nylon roller brush has uniform paint, but has high cost, high price and high contrast, is difficult to be widely accepted in the market and has low utilization rate.
At present, the equipment of domestic brush velvet production enterprises is relatively lagged behind, and the deep processing operation of products cannot be realized due to low technical level of the process, so that the added value of the products is reduced, the utilization rate is low, and the profit margin is small. The method is mainly embodied in the following points: (1) the post-finishing procedures are not fine enough in process control, so that the suede is uneven, poor in elasticity, rough in hand feeling, not full enough and low in product grade; (2) the traditional sizing cloth drying process does not consider the thermal stability and glass transition temperature of the synthetic fiber and does not give full play to the performance of the fiber.

Polyester high stretch yarn and low stretch yarn: the polyester fiber filament is made into a spiral ring shape through one-time heating deformation, has high elastic expansion rate, and is called as high stretch yarn. Generally speaking, the difference between low stretch yarn and high stretch yarn means that when ordinary polyester is textured, the second hot box of the texturing machine is opened to form low stretch yarn, and the second hot box is not opened to form high stretch yarn (the elasticity is better than the low stretch yarn).
Polyester interlaced yarn: when the common polyester filament yarn passes through a network nozzle, several single filaments are intertwined with each other under the action of jet air flow to form a polyester processing yarn with slight elasticity and fluffiness and a periodic 'network point'.

The terylene roller brushed warp knitting product with high resilience suede performance mainly comprises the following components: pile warp and ground warp.
Pile warp: the adopted 300D/96F polyester high stretch yarn has the advantages of high modulus, high strength, high elasticity, good shape retention, good heat resistance and the like.
Ground warp: a division into outer and inner filaments, also known as chaining and weft insertion, is shown in fig. 4. The same raw material 150D/35F polyester filament yarn is adopted for the chaining and the weft insertion, and the polyester filament yarn has small elasticity and high strength. The dimensional stability of the fabric can be effectively improved by inserting the yarns with smaller elasticity and extensibility. The tearing strength and the stability of the fabric can be improved by utilizing the high-strength chaining.
Weaving by adopting a double-needle bed warp knitting machine; setting 12 small warp beams at the front and the back of the double-needle bed warp knitting machine together, and warping separately; the pile warp can be hung on a creel by a warping beam or directly by cone yarn; the used double needle bar warp knitting machine consists of 5 guide bars, the knitting wool height is 4.5-50mm, and the speed is between 300 and 800 r/min; in the looping configuration, guide bars GB1, GB2, GB5 and GB6 are fixed on a frame, and during weaving, 4 guide bars are transversely moved left and right without swinging back and forth; the movement condition of the guide bar GB3 is determined by the distance between the knockover plates, GB3 does left-right shogging movement and also does back-and-forth swing in the opposite direction of the knockover plates, so that the problems of distance increase and speed reduction of the knockover plates are solved.
